- There are many external CD-ROM and disk devices that connect through

- using a parallel port IDE adapter. This option enables the PARIDE
- subsystem which contains drivers for many of these external drives.
- Read <file:Documentation/admin-guide/blockdev/paride.rst> for more information.

- If you have said Y to the "Parallel-port support" configuration
- option, you may share a single port between your printer and other
- parallel port devices. Answer Y to build PARIDE support into your
- kernel, or M if you would like to build it as a loadable module. If
- your parallel port support is in a loadable module, you must build
- PARIDE as a module. If you built PARIDE support into your kernel,
- you may still build the individual protocol modules and high-level
- drivers as loadable modules. If you build this support as a module,

-Lemma 1:
- If ps_tq is scheduled, ps_tq_active is 1. ps_tq_int() can be called
- only when ps_tq_active is 1.
-Proof: All assignments to ps_tq_active and all scheduling of ps_tq happen
- under ps_spinlock. There are three places where that can happen:
- one in ps_set_intr() (A) and two in ps_tq_int() (B and C).
- Consider the sequnce of these events. A can not be preceded by
- anything except B, since it is under if (!ps_tq_active) under
- ps_spinlock. C is always preceded by B, since we can't reach it
- other than through B and we don't drop ps_spinlock between them.
- IOW, the sequence is A?(BA|BC|B)*. OTOH, number of B can not exceed
- the sum of numbers of A and C, since each call of ps_tq_int() is
- the result of ps_tq execution. Therefore, the sequence starts with
- A and each B is preceded by either A or C. Moments when we enter
- ps_tq_int() are sandwiched between {A,C} and B in that sequence,
- since at any time number of B can not exceed the number of these
- moments which, in turn, can not exceed the number of A and C.
- In other words, the sequence of events is (A or C set ps_tq_active to
- 1 and schedule ps_tq, ps_tq is executed, ps_tq_int() is entered,
- B resets ps_tq_active)*.
-
-
-consider the following area:
- * in do_pd_request1(): to calls of pi_do_claimed() and return in
- case when pd_req is NULL.
- * in next_request(): to call of do_pd_request1()
- * in do_pd_read(): to call of ps_set_intr()
- * in do_pd_read_start(): to calls of pi_do_claimed(), next_request()
-and ps_set_intr()
- * in do_pd_read_drq(): to calls of pi_do_claimed() and next_request()
- * in do_pd_write(): to call of ps_set_intr()
- * in do_pd_write_start(): to calls of pi_do_claimed(), next_request()
-and ps_set_intr()
- * in do_pd_write_done(): to calls of pi_do_claimed() and next_request()
- * in ps_set_intr(): to check for ps_tq_active and to scheduling
- ps_tq if ps_tq_active was 0.
- * in ps_tq_int(): from the moment when we get ps_spinlock() to the
- return, call of con() or scheduling ps_tq.
- * in pi_schedule_claimed() when called from pi_do_claimed() called from
- pd.c, everything until returning 1 or setting or setting ->claim_cont
- on the path that returns 0
- * in pi_do_claimed() when called from pd.c, everything until the call
- of pi_do_claimed() plus the everything until the call of cont() if
- pi_do_claimed() has returned 1.
- * in pi_wake_up() called for PIA that belongs to pd.c, everything from
- the moment when pi_spinlock has been acquired.
-
-Lemma 2:
- 1) at any time at most one thread of execution can be in that area or
- be preempted there.
- 2) When there is such a thread, pd_busy is set or pd_lock is held by
- that thread.
- 3) When there is such a thread, ps_tq_active is 0 or ps_spinlock is
- held by that thread.
- 4) When there is such a thread, all PIA belonging to pd.c have NULL
- ->claim_cont or pi_spinlock is held by thread in question.
-
-Proof: consider the first moment when the above is not true.
-
-(1) can become not true if some thread enters that area while another is there.
- a) do_pd_request1() can be called from next_request() or do_pd_request()
- In the first case the thread was already in the area. In the second,
- the thread was holding pd_lock and found pd_busy not set, which would
- mean that (2) was already not true.
- b) ps_set_intr() and pi_schedule_claimed() can be called only from the
- area.
- c) pi_do_claimed() is called by pd.c only from the area.
- d) ps_tq_int() can enter the area only when the thread is holding
- ps_spinlock and ps_tq_active is 1 (due to Lemma 1). It means that
- (3) was already not true.
- e) do_pd_{read,write}* could be called only from the area. The only
- case that needs consideration is call from pi_wake_up() and there
- we would have to be called for the PIA that got ->claimed_cont
- from pd.c. That could happen only if pi_do_claimed() had been
- called from pd.c for that PIA, which happens only for PIA belonging
- to pd.c.
- f) pi_wake_up() can enter the area only when the thread is holding
- pi_spinlock and ->claimed_cont is non-NULL for PIA belonging to
- pd.c. It means that (4) was already not true.
-
-(2) can become not true only when pd_lock is released by the thread in question.
- Indeed, pd_busy is reset only in the area and thread that resets
- it is holding pd_lock. The only place within the area where we
- release pd_lock is in pd_next_buf() (called from within the area).
- But that code does not reset pd_busy, so pd_busy would have to be
- 0 when pd_next_buf() had acquired pd_lock. If it become 0 while
- we were acquiring the lock, (1) would be already false, since
- the thread that had reset it would be in the area simulateously.
- If it was 0 before we tried to acquire pd_lock, (2) would be
- already false.
-
-For similar reasons, (3) can become not true only when ps_spinlock is released
-by the thread in question. However, all such places within the area are right
-after resetting ps_tq_active to 0.
-
-(4) is done the same way - all places where we release pi_spinlock within
-the area are either after resetting ->claimed_cont to NULL while holding
-pi_spinlock, or after not tocuhing ->claimed_cont since acquiring pi_spinlock
-also in the area. The only place where ->claimed_cont is made non-NULL is
-in the area, under pi_spinlock and we do not release it until after leaving
-the area.
-
-QED.
-
-
-Corollary 1: ps_tq_active can be killed. Indeed, the only place where we
-check its value is in ps_set_intr() and if it had been non-zero at that
-point, we would have violated either (2.1) (if it was set while ps_set_intr()
-was acquiring ps_spinlock) or (2.3) (if it was set when we started to
-acquire ps_spinlock).
-
-Corollary 2: ps_spinlock can be killed. Indeed, Lemma 1 and Lemma 2 show
-that the only possible contention is between scheduling ps_tq followed by
-immediate release of spinlock and beginning of execution of ps_tq on
-another CPU.
-
-Corollary 3: assignment to pd_busy in do_pd_read_start() and do_pd_write_start()
-can be killed. Indeed, we are not holding pd_lock and thus pd_busy is already
-1 here.
-
-Corollary 4: in ps_tq_int() uses of con can be replaced with uses of
-ps_continuation, since the latter is changed only from the area.
-We don't need to reset it to NULL, since we are guaranteed that there
-will be a call of ps_set_intr() before we look at ps_continuation again.
-We can remove the check for ps_continuation being NULL for the same
-reason - the value is guaranteed to be set by the last ps_set_intr() and
-we never pass it NULL. Assignements in the beginning of ps_set_intr()
-can be taken to callers as long as they remain within the area.

- pcd.c (c) 1997-8 Grant R. Guenther <grant@torque.net>
- Under the terms of the GNU General Public License.
-
- This is a high-level driver for parallel port ATAPI CD-ROM
- drives based on chips supported by the paride module.
-
- By default, the driver will autoprobe for a single parallel
- port ATAPI CD-ROM drive, but if their individual parameters are
- specified, the driver can handle up to 4 drives.
-
- The behaviour of the pcd driver can be altered by setting
- some parameters from the insmod command line. The following
- parameters are adjustable:
-
- drive0 These four arguments can be arrays of
- drive1 1-6 integers as follows:
- drive2
- drive3 <prt>,<pro>,<uni>,<mod>,<slv>,<dly>
-
- Where,
-
- <prt> is the base of the parallel port address for
- the corresponding drive. (required)
-
- <pro> is the protocol number for the adapter that
- supports this drive. These numbers are
- logged by 'paride' when the protocol modules
- are initialised. (0 if not given)
-
- <uni> for those adapters that support chained
- devices, this is the unit selector for the
- chain of devices on the given port. It should
- be zero for devices that don't support chaining.
- (0 if not given)
-
- <mod> this can be -1 to choose the best mode, or one
- of the mode numbers supported by the adapter.
- (-1 if not given)
-
- <slv> ATAPI CD-ROMs can be jumpered to master or slave.
- Set this to 0 to choose the master drive, 1 to
- choose the slave, -1 (the default) to choose the
- first drive found.
-
- <dly> some parallel ports require the driver to
- go more slowly. -1 sets a default value that
- should work with the chosen protocol. Otherwise,
- set this to a small integer, the larger it is
- the slower the port i/o. In some cases, setting
- this to zero will speed up the device. (default -1)
-
- major You may use this parameter to override the
- default major number (46) that this driver
- will use. Be sure to change the device
- name as well.
-
- name This parameter is a character string that
- contains the name the kernel will use for this
- device (in /proc output, for instance).
- (default "pcd")
-
- verbose This parameter controls the amount of logging
- that the driver will do. Set it to 0 for
- normal operation, 1 to see autoprobe progress
- messages, or 2 to see additional debugging
- output. (default 0)
-
- nice This parameter controls the driver's use of
- idle CPU time, at the expense of some speed.
-
- If this driver is built into the kernel, you can use the
- following kernel command line parameters, with the same values
- as the corresponding module parameters listed above:
-
- pcd.drive0
- pcd.drive1
- pcd.drive2
- pcd.drive3
- pcd.nice
-
- In addition, you can use the parameter pcd.disable to disable
- the driver entirely.

-/*
- pd.c (c) 1997-8 Grant R. Guenther <grant@torque.net>
- Under the terms of the GNU General Public License.
-
- This is the high-level driver for parallel port IDE hard
- drives based on chips supported by the paride module.
-
- By default, the driver will autoprobe for a single parallel
- port IDE drive, but if their individual parameters are
- specified, the driver can handle up to 4 drives.
-
- The behaviour of the pd driver can be altered by setting
- some parameters from the insmod command line. The following
- parameters are adjustable:
-
- drive0 These four arguments can be arrays of
- drive1 1-8 integers as follows:
- drive2
- drive3 <prt>,<pro>,<uni>,<mod>,<geo>,<sby>,<dly>,<slv>
-
- Where,
-
- <prt> is the base of the parallel port address for
- the corresponding drive. (required)
-
- <pro> is the protocol number for the adapter that
- supports this drive. These numbers are
- logged by 'paride' when the protocol modules
- are initialised. (0 if not given)
-
- <uni> for those adapters that support chained
- devices, this is the unit selector for the
- chain of devices on the given port. It should
- be zero for devices that don't support chaining.
- (0 if not given)
-
- <mod> this can be -1 to choose the best mode, or one
- of the mode numbers supported by the adapter.
- (-1 if not given)
-
- <geo> this defaults to 0 to indicate that the driver
- should use the CHS geometry provided by the drive
- itself. If set to 1, the driver will provide
- a logical geometry with 64 heads and 32 sectors
- per track, to be consistent with most SCSI
- drivers. (0 if not given)
-
- <sby> set this to zero to disable the power saving
- standby mode, if needed. (1 if not given)
-
- <dly> some parallel ports require the driver to
- go more slowly. -1 sets a default value that
- should work with the chosen protocol. Otherwise,
- set this to a small integer, the larger it is
- the slower the port i/o. In some cases, setting
- this to zero will speed up the device. (default -1)
-
- <slv> IDE disks can be jumpered to master or slave.
- Set this to 0 to choose the master drive, 1 to
- choose the slave, -1 (the default) to choose the
- first drive found.
-
-
- major You may use this parameter to override the
- default major number (45) that this driver
- will use. Be sure to change the device
- name as well.
-
- name This parameter is a character string that
- contains the name the kernel will use for this
- device (in /proc output, for instance).
- (default "pd")
-
- cluster The driver will attempt to aggregate requests
- for adjacent blocks into larger multi-block
- clusters. The maximum cluster size (in 512
- byte sectors) is set with this parameter.
- (default 64)
-
- verbose This parameter controls the amount of logging
- that the driver will do. Set it to 0 for
- normal operation, 1 to see autoprobe progress
- messages, or 2 to see additional debugging
- output. (default 0)
-
- nice This parameter controls the driver's use of
- idle CPU time, at the expense of some speed.
-
- If this driver is built into the kernel, you can use kernel
- the following command line parameters, with the same values
- as the corresponding module parameters listed above:
-
- pd.drive0
- pd.drive1
- pd.drive2
- pd.drive3
- pd.cluster
- pd.nice
-
- In addition, you can use the parameter pd.disable to disable
- the driver entirely.

-/*
- pf.c (c) 1997-8 Grant R. Guenther <grant@torque.net>
- Under the terms of the GNU General Public License.
-
- This is the high-level driver for parallel port ATAPI disk
- drives based on chips supported by the paride module.
-
- By default, the driver will autoprobe for a single parallel
- port ATAPI disk drive, but if their individual parameters are
- specified, the driver can handle up to 4 drives.
-
- The behaviour of the pf driver can be altered by setting
- some parameters from the insmod command line. The following
- parameters are adjustable:
-
- drive0 These four arguments can be arrays of
- drive1 1-7 integers as follows:
- drive2
- drive3 <prt>,<pro>,<uni>,<mod>,<slv>,<lun>,<dly>
-
- Where,
-
- <prt> is the base of the parallel port address for
- the corresponding drive. (required)
-
- <pro> is the protocol number for the adapter that
- supports this drive. These numbers are
- logged by 'paride' when the protocol modules
- are initialised. (0 if not given)
-
- <uni> for those adapters that support chained
- devices, this is the unit selector for the
- chain of devices on the given port. It should
- be zero for devices that don't support chaining.
- (0 if not given)
-
- <mod> this can be -1 to choose the best mode, or one
- of the mode numbers supported by the adapter.
- (-1 if not given)
-
- <slv> ATAPI CDroms can be jumpered to master or slave.
- Set this to 0 to choose the master drive, 1 to
- choose the slave, -1 (the default) to choose the
- first drive found.
-
- <lun> Some ATAPI devices support multiple LUNs.
- One example is the ATAPI PD/CD drive from
- Matshita/Panasonic. This device has a
- CD drive on LUN 0 and a PD drive on LUN 1.
- By default, the driver will search for the
- first LUN with a supported device. Set
- this parameter to force it to use a specific
- LUN. (default -1)
-
- <dly> some parallel ports require the driver to
- go more slowly. -1 sets a default value that
- should work with the chosen protocol. Otherwise,
- set this to a small integer, the larger it is
- the slower the port i/o. In some cases, setting
- this to zero will speed up the device. (default -1)
-
- major You may use this parameter to override the
- default major number (47) that this driver
- will use. Be sure to change the device
- name as well.
-
- name This parameter is a character string that
- contains the name the kernel will use for this
- device (in /proc output, for instance).
- (default "pf").
-
- cluster The driver will attempt to aggregate requests
- for adjacent blocks into larger multi-block
- clusters. The maximum cluster size (in 512
- byte sectors) is set with this parameter.
- (default 64)
-
- verbose This parameter controls the amount of logging
- that the driver will do. Set it to 0 for
- normal operation, 1 to see autoprobe progress
- messages, or 2 to see additional debugging
- output. (default 0)
-
- nice This parameter controls the driver's use of
- idle CPU time, at the expense of some speed.
-
- If this driver is built into the kernel, you can use the
- following command line parameters, with the same values
- as the corresponding module parameters listed above:
-
- pf.drive0
- pf.drive1
- pf.drive2
- pf.drive3
- pf.cluster
- pf.nice
-
- In addition, you can use the parameter pf.disable to disable
- the driver entirely.

-/*
- pg.c (c) 1998 Grant R. Guenther <grant@torque.net>
- Under the terms of the GNU General Public License.
-
- The pg driver provides a simple character device interface for
- sending ATAPI commands to a device. With the exception of the
- ATAPI reset operation, all operations are performed by a pair
- of read and write operations to the appropriate /dev/pgN device.
- A write operation delivers a command and any outbound data in
- a single buffer. Normally, the write will succeed unless the
- device is offline or malfunctioning, or there is already another
- command pending. If the write succeeds, it should be followed
- immediately by a read operation, to obtain any returned data and
- status information. A read will fail if there is no operation
- in progress.
-
- As a special case, the device can be reset with a write operation,
- and in this case, no following read is expected, or permitted.
-
- There are no ioctl() operations. Any single operation
- may transfer at most PG_MAX_DATA bytes. Note that the driver must
- copy the data through an internal buffer. In keeping with all
- current ATAPI devices, command packets are assumed to be exactly
- 12 bytes in length.
-
- To permit future changes to this interface, the headers in the
- read and write buffers contain a single character "magic" flag.
- Currently this flag must be the character "P".
-
- By default, the driver will autoprobe for a single parallel
- port ATAPI device, but if their individual parameters are
- specified, the driver can handle up to 4 devices.
-
- To use this device, you must have the following device
- special files defined:
-
- /dev/pg0 c 97 0
- /dev/pg1 c 97 1
- /dev/pg2 c 97 2
- /dev/pg3 c 97 3
-
- (You'll need to change the 97 to something else if you use
- the 'major' parameter to install the driver on a different
- major number.)
-
- The behaviour of the pg driver can be altered by setting
- some parameters from the insmod command line. The following
- parameters are adjustable:
-
- drive0 These four arguments can be arrays of
- drive1 1-6 integers as follows:
- drive2
- drive3 <prt>,<pro>,<uni>,<mod>,<slv>,<dly>
-
- Where,
-
- <prt> is the base of the parallel port address for
- the corresponding drive. (required)
-
- <pro> is the protocol number for the adapter that
- supports this drive. These numbers are
- logged by 'paride' when the protocol modules
- are initialised. (0 if not given)
-
- <uni> for those adapters that support chained
- devices, this is the unit selector for the
- chain of devices on the given port. It should
- be zero for devices that don't support chaining.
- (0 if not given)
-
- <mod> this can be -1 to choose the best mode, or one
- of the mode numbers supported by the adapter.
- (-1 if not given)
-
- <slv> ATAPI devices can be jumpered to master or slave.
- Set this to 0 to choose the master drive, 1 to
- choose the slave, -1 (the default) to choose the
- first drive found.
-
- <dly> some parallel ports require the driver to
- go more slowly. -1 sets a default value that
- should work with the chosen protocol. Otherwise,
- set this to a small integer, the larger it is
- the slower the port i/o. In some cases, setting
- this to zero will speed up the device. (default -1)
-
- major You may use this parameter to override the
- default major number (97) that this driver
- will use. Be sure to change the device
- name as well.
-
- name This parameter is a character string that
- contains the name the kernel will use for this
- device (in /proc output, for instance).
- (default "pg").
-
- verbose This parameter controls the amount of logging
- that is done by the driver. Set it to 0 for
- quiet operation, to 1 to enable progress
- messages while the driver probes for devices,
- or to 2 for full debug logging. (default 0)
-
- If this driver is built into the kernel, you can use
- the following command line parameters, with the same values
- as the corresponding module parameters listed above:
-
- pg.drive0
- pg.drive1
- pg.drive2
- pg.drive3
-
- In addition, you can use the parameter pg.disable to disable
- the driver entirely.

-/*
- pt.c (c) 1998 Grant R. Guenther <grant@torque.net>
- Under the terms of the GNU General Public License.
-
- This is the high-level driver for parallel port ATAPI tape
- drives based on chips supported by the paride module.
-
- The driver implements both rewinding and non-rewinding
- devices, filemarks, and the rewind ioctl. It allocates
- a small internal "bounce buffer" for each open device, but
- otherwise expects buffering and blocking to be done at the
- user level. As with most block-structured tapes, short
- writes are padded to full tape blocks, so reading back a file
- may return more data than was actually written.
-
- By default, the driver will autoprobe for a single parallel
- port ATAPI tape drive, but if their individual parameters are
- specified, the driver can handle up to 4 drives.
-
- The rewinding devices are named /dev/pt0, /dev/pt1, ...
- while the non-rewinding devices are /dev/npt0, /dev/npt1, etc.
-
- The behaviour of the pt driver can be altered by setting
- some parameters from the insmod command line. The following
- parameters are adjustable:
-
- drive0 These four arguments can be arrays of
- drive1 1-6 integers as follows:
- drive2
- drive3 <prt>,<pro>,<uni>,<mod>,<slv>,<dly>
-
- Where,
-
- <prt> is the base of the parallel port address for
- the corresponding drive. (required)
-
- <pro> is the protocol number for the adapter that
- supports this drive. These numbers are
- logged by 'paride' when the protocol modules
- are initialised. (0 if not given)
-
- <uni> for those adapters that support chained
- devices, this is the unit selector for the
- chain of devices on the given port. It should
- be zero for devices that don't support chaining.
- (0 if not given)
-
- <mod> this can be -1 to choose the best mode, or one
- of the mode numbers supported by the adapter.
- (-1 if not given)
-
- <slv> ATAPI devices can be jumpered to master or slave.
- Set this to 0 to choose the master drive, 1 to
- choose the slave, -1 (the default) to choose the
- first drive found.
-
- <dly> some parallel ports require the driver to
- go more slowly. -1 sets a default value that
- should work with the chosen protocol. Otherwise,
- set this to a small integer, the larger it is
- the slower the port i/o. In some cases, setting
- this to zero will speed up the device. (default -1)
-
- major You may use this parameter to override the
- default major number (96) that this driver
- will use. Be sure to change the device
- name as well.
-
- name This parameter is a character string that
- contains the name the kernel will use for this
- device (in /proc output, for instance).
- (default "pt").
-
- verbose This parameter controls the amount of logging
- that the driver will do. Set it to 0 for
- normal operation, 1 to see autoprobe progress
- messages, or 2 to see additional debugging
- output. (default 0)
-
- If this driver is built into the kernel, you can use
- the following command line parameters, with the same values
- as the corresponding module parameters listed above:
-
- pt.drive0
- pt.drive1
- pt.drive2
- pt.drive3
-
- In addition, you can use the parameter pt.disable to disable
- the driver entirely.

+ * Packet writing layer for ATAPI and SCSI CD-RW, DVD+RW, DVD-RW and
+ * DVD-RAM devices.
+ *
+ * Theory of operation:
+ *
+ * At the lowest level, there is the standard driver for the CD/DVD device,
+ * such as drivers/scsi/sr.c. This driver can handle read and write requests,
+ * but it doesn't know anything about the special restrictions that apply to
+ * packet writing. One restriction is that write requests must be aligned to
+ * packet boundaries on the physical media, and the size of a write request
+ * must be equal to the packet size. Another restriction is that a
+ * GPCMD_FLUSH_CACHE command has to be issued to the drive before a read
+ * command, if the previous command was a write.
+ *
+ * The purpose of the packet writing driver is to hide these restrictions from
+ * higher layers, such as file systems, and present a block device that can be
+ * randomly read and written using 2kB-sized blocks.
+ *
+ * The lowest layer in the packet writing driver is the packet I/O scheduler.
+ * Its data is defined by the struct packet_iosched and includes two bio
+ * queues with pending read and write requests. These queues are processed
+ * by the pkt_iosched_process_queue() function. The write requests in this
+ * queue are already properly aligned and sized. This layer is responsible for
+ * issuing the flush cache commands and scheduling the I/O in a good order.
+ *
+ * The next layer transforms unaligned write requests to aligned writes. This
+ * transformation requires reading missing pieces of data from the underlying
+ * block device, assembling the pieces to full packets and queuing them to the
+ * packet I/O scheduler.
+ *
+ * At the top layer there is a custom ->submit_bio function that forwards
+ * read requests directly to the iosched queue and puts write requests in the
+ * unaligned write queue. A kernel thread performs the necessary read
+ * gathering to convert the unaligned writes to aligned writes and then feeds
+ * them to the packet I/O scheduler.

- * Theory of operations
- * ====================
- *
- * Clock scaling can be used to lower the power consumption of the CPU
- * core. This will give you a somewhat longer running time.
- *
- * The SA-1100 has a single register to change the core clock speed:
- *
- * PPCR 0x90020014 PLL config
- *
- * However, the DRAM timings are closely related to the core clock
- * speed, so we need to change these, too. The used registers are:
- *
- * MDCNFG 0xA0000000 DRAM config
- * MDCAS0 0xA0000004 Access waveform
- * MDCAS1 0xA0000008 Access waveform
- * MDCAS2 0xA000000C Access waveform
- *
- * Care must be taken to change the DRAM parameters the correct way,
- * because otherwise the DRAM becomes unusable and the kernel will
- * crash.
- *
- * The simple solution to avoid a kernel crash is to put the actual
- * clock change in ROM and jump to that code from the kernel. The main
- * disadvantage is that the ROM has to be modified, which is not
- * possible on all SA-1100 platforms. Another disadvantage is that
- * jumping to ROM makes clock switching unnecessary complicated.
- *
- * The idea behind this driver is that the memory configuration can be
- * changed while running from DRAM (even with interrupts turned on!)
- * as long as all re-configuration steps yield a valid DRAM
- * configuration. The advantages are clear: it will run on all SA-1100
- * platforms, and the code is very simple.
- *
- * If you really want to understand what is going on in
- * sa1100_update_dram_timings(), you'll have to read sections 8.2,
- * 9.5.7.3, and 10.2 from the "Intel StrongARM SA-1100 Microprocessor
- * Developers Manual" (available for free from Intel).

+ *
+ * Util-awareness mechanism:
+ *
+ * The idea behind the util-awareness extension is that there are two distinct
+ * scenarios for the CPU which should result in two different approaches to idle
+ * state selection - utilized and not utilized.
+ *
+ * In this case, 'utilized' means that the average runqueue util of the CPU is
+ * above a certain threshold.
+ *
+ * When the CPU is utilized while going into idle, more likely than not it will
+ * be woken up to do more work soon and so a shallower idle state should be
+ * selected to minimise latency and maximise performance. When the CPU is not
+ * being utilized, the usual metrics-based approach to selecting the deepest
+ * available idle state should be preferred to take advantage of the power
+ * saving.
+ *
+ * In order to achieve this, the governor uses a utilization threshold.
+ * The threshold is computed per-CPU as a percentage of the CPU's capacity
+ * by bit shifting the capacity value. Based on testing, the shift of 6 (~1.56%)
+ * seems to be getting the best results.
+ *
+ * Before selecting the next idle state, the governor compares the current CPU
+ * util to the precomputed util threshold. If it's below, it defaults to the
+ * TEO metrics mechanism. If it's above, the closest shallower idle state will
+ * be selected instead, as long as is not a polling state.

+/**
+ * DOC: Theory of operation
+ *
+ * When enabled the SCMI Raw mode support exposes a userspace API which allows
+ * to send and receive SCMI commands, replies and notifications from a user
+ * application through injection and snooping of bare SCMI messages in binary
+ * little-endian format.
+ *
+ * Such injected SCMI transactions will then be routed through the SCMI core
+ * stack towards the SCMI backend server using whatever SCMI transport is
+ * currently configured on the system under test.
+ *
+ * It is meant to help in running any sort of SCMI backend server testing, no
+ * matter where the server is placed, as long as it is normally reachable via
+ * the transport configured on the system.
+ *
+ * It is activated by a Kernel configuration option since it is NOT meant to
+ * be used in production but only during development and in CI deployments.
+ *
+ * In order to avoid possible interferences between the SCMI Raw transactions
+ * originated from a test-suite and the normal operations of the SCMI drivers,
+ * when Raw mode is enabled, by default, all the regular SCMI drivers are
+ * inhibited, unless CONFIG_ARM_SCMI_RAW_MODE_SUPPORT_COEX is enabled: in this
+ * latter case the regular SCMI stack drivers will be loaded as usual and it is
+ * up to the user of this interface to take care of manually inhibiting the
+ * regular SCMI drivers in order to avoid interferences during the test runs.
+ *
+ * The exposed API is as follows.
+ *
+ * All SCMI Raw entries are rooted under a common top /raw debugfs top directory
+ * which in turn is rooted under the corresponding underlying SCMI instance.
+ *
+ * /sys/kernel/debug/scmi/
+ * `-- 0
+ * |-- atomic_threshold_us
+ * |-- instance_name
+ * |-- raw
+ * | |-- channels
+ * | | |-- 0x10
+ * | | | |-- message
+ * | | | `-- message_async
+ * | | `-- 0x13

+ * |-- max_msg_size
+ * |-- max_rx_timeout_ms
+ * |-- rx_max_msg
+ * |-- tx_max_msg
+ * `-- type
+ *
+ * where:
+ *
+ * - errors: used to read back timed-out and unexpected replies
+ * - message*: used to send sync/async commands and read back immediate and
+ * delayed reponses (if any)
+ * - notification: used to read any notification being emitted by the system
+ * (if previously enabled by the user app)
+ * - reset: used to flush the queues of messages (of any kind) still pending
+ * to be read; this is useful at test-suite start/stop to get
+ * rid of any unread messages from the previous run.
+ *
+ * with the per-channel entries rooted at /channels being present only on a
+ * system where multiple transport channels have been configured.
+ *
+ * Such per-channel entries can be used to explicitly choose a specific channel
+ * for SCMI bare message injection, in contrast with the general entries above
+ * where, instead, the selection of the proper channel to use is automatically
+ * performed based the protocol embedded in the injected message and on how the
+ * transport is configured on the system.
+ *
+ * Note that other common general entries are available under transport/ to let
+ * the user applications properly make up their expectations in terms of
+ * timeouts and message characteristics.
+ *
+ * Each write to the message* entries causes one command request to be built
+ * and sent while the replies or delayed response are read back from those same
+ * entries one message at time (receiving an EOF at each message boundary).
+ *
+ * The user application running the test is in charge of handling timeouts
+ * on replies and properly choosing SCMI sequence numbers for the outgoing
+ * requests (using the same sequence number is supported but discouraged).
+ *
+ * Injection of multiple in-flight requests is supported as long as the user
+ * application uses properly distinct sequence numbers for concurrent requests
+ * and takes care to properly manage all the related issues about concurrency
+ * and command/reply pairing. Keep in mind that, anyway, the real level of
+ * parallelism attainable in such scenario is dependent on the characteristics
+ * of the underlying transport being used.
+ *
+ * Since the SCMI core regular stack is partially used to deliver and collect
+ * the messages, late replies arrived after timeouts and any other sort of
+ * unexpected message can be identified by the SCMI core as usual and they will
+ * be reported as messages under "errors" for later analysis.

+/**
+ * DOC: dsi bridge operations
+ *
+ * DSI host interfaces are expected to be implemented as bridges rather than
+ * encoders, however there are a few aspects of their operation that need to
+ * be defined in order to provide a consistent interface.
+ *
+ * A DSI host should keep the PHY powered down until the pre_enable operation is
+ * called. All lanes are in an undefined idle state up to this point, and it
+ * must not be assumed that it is LP-11.
+ * pre_enable should initialise the PHY, set the data lanes to LP-11, and the
+ * clock lane to either LP-11 or HS depending on the mode_flag
+ * %MIPI_DSI_CLOCK_NON_CONTINUOUS.
+ *
+ * Ordinarily the downstream bridge DSI peripheral pre_enable will have been
+ * called before the DSI host. If the DSI peripheral requires LP-11 and/or
+ * the clock lane to be in HS mode prior to pre_enable, then it can set the
+ * &pre_enable_prev_first flag to request the pre_enable (and
+ * post_disable) order to be altered to enable the DSI host first.
+ *
+ * Either the CRTC being enabled, or the DSI host enable operation should switch
+ * the host to actively transmitting video on the data lanes.
+ *
+ * The reverse also applies. The DSI host disable operation or stopping the CRTC
+ * should stop transmitting video, and the data lanes should return to the LP-11
+ * state. The DSI host &post_disable operation should disable the PHY.
+ * If the &pre_enable_prev_first flag is set, then the DSI peripheral's
+ * bridge &post_disable will be called before the DSI host's post_disable.
+ *
+ * Whilst it is valid to call &host_transfer prior to pre_enable or after
+ * post_disable, the exact state of the lanes is undefined at this point. The
+ * DSI host should initialise the interface, transmit the data, and then disable
+ * the interface again.
+ *
+ * Ultra Low Power State (ULPS) is not explicitly supported by DRM. If
+ * implemented, it therefore needs to be handled entirely within the DSI Host
+ * driver.

+ *
+ * 0. Unbind all objects that do not match the GTT constraints for the

*
- * 1. Unbind all objects that do not match the GTT constraints for
- * the execbuffer (fenceable, mappable, alignment etc).
- * 2. Bind new objects.
+ * 1. Reorder the buffers, where objects with the most restrictive
+ * placement requirements go first (ignoring fixed location buffers for
+ * now). For example, objects needing the mappable aperture (the first
+ * 256M of GTT), should go first vs objects that can be placed just
+ * about anywhere. Repeat the previous pass.
*
- * This avoid unnecessary unbinding of later objects in order to make
- * room for the earlier objects *unless* we need to defragment.
+ * 2. Consider buffers that are pinned at a fixed location. Also try to
+ * evict the entire VM this time, leaving only objects that we were
+ * unable to lock. Try again to bind the buffers. (still using the new
+ * buffer order).
*
- * Defragmenting is skipped if all objects are pinned at a fixed location.
+ * 3. We likely have object lock contention for one or more stubborn
+ * objects in the VM, for which we need to evict to make forward
+ * progress (perhaps we are fighting the shrinker?). When evicting the
+ * VM this time around, anything that we can't lock we now track using

+ * the access to the MMIO bar, which means we need to do it as part of

+ * An alternative approach to the FLR would be to use a memory location
+ * that survives driver unload, like e.g. stolen memory, and keep the

- * the change the muxing between FIFOs and outputs in
- * the HVS accordingly.
- *
- * It would be pretty hard to come up with an
- * algorithm that would generically solve
- * this. However, the current routing trees we support
- * allow us to simplify a bit the problem.
- *
- * Indeed, with the current supported layouts, if we
- * try to assign in the ascending crtc index order the
- * FIFOs, we can't fall into the situation where an
- * earlier CRTC that had multiple routes is assigned
- * one that was the only option for a later CRTC.
- *
- * If the layout changes and doesn't give us that in
- * the future, we will need to have something smarter,
- * but it works so far.

+ * Field only valid when flow_override_enable is set to FP_USE_OVERRIDE
+ * TCL uses this to select the flow pointer from the peer table,

+ * that cannot be parsed for UDP or for other MLO
+ * 0 - FP_USE_NON_UDP: Use the non-UDP flow pointer (flow 0)
+ * 1 - FP_USE_UDP: Use the UDP flow pointer (flow 1)
+ *
+ * pmac_id
+ * TCL uses this PMAC_ID in address search, i.e, while
+ * finding matching entry for the packet in AST corresponding
+ * to given PMAC_ID
+ *
+ * If PMAC ID is all 1s (=> value 3), it indicates wildcard
+ * match for any PMAC
+ *
+ * vdev_id
+ * Virtual device ID to check against the address search entry to
+ * avoid security issues from transmitting packets from an incorrect
+ * virtual device
+ *
+ * search_index
+ * The index that will be used for index based address or
+ * flow search. The field is valid when 'search_type' is 1 or 2.
+ *
+ * cache_set_num
+ *
+ * Cache set number that should be used to cache the index
+ * based search results, for address and flow search. This
+ * value should be equal to LSB four bits of the hash value of
+ * match data, in case of search index points to an entry which
+ * may be used in content based search also. The value can be
+ * anything when the entry pointed by search index will not be
+ * used for content based search.
+ *
+ * index_loop_override
+ * When set, address search and packet routing is forced to use
+ * 'search_index' instead of following the register configuration
+ * seleced by Bank_id.
+ *
+ * ring_id
+ * The buffer pointer ring ID.
+ * 0 refers to the IDLE ring
+ * 1 - N refers to other rings
+ *
+ * looping_count
+ *
+ * A count value that indicates the number of times the
+ * producer of entries into the Ring has looped around the
+ * ring.
+ *
+ * At initialization time, this value is set to 0. On the
+ * first loop, this value is set to 1. After the max value is
+ * reached allowed by the number of bits for this field, the
+ * count value continues with 0 again.
+ *
+ * In case SW is the consumer of the ring entries, it can
+ * use this field to figure out up to where the producer of
+ * entries has created new entries. This eliminates the need to
+ * check where the head pointer' of the ring is located once
+ * the SW starts processing an interrupt indicating that new
+ * entries have been put into this ring...
+ *
+ * Also note that SW if it wants only needs to look at the

- * BadgePAD 4 Details
- *
- * PCM Vcc:
- *
- * PCM Vcc on BadgePAD 4 can be jumpered for 3v3 (short pins 1 and 3
- * on JP6) or 5v0 (short pins 3 and 5 on JP6).
- *
- * PCM Vpp:
- *
- * PCM Vpp on BadgePAD 4 can be jumpered for 12v0 (short pins 4 and 6
- * on JP6) or tied to PCM Vcc (short pins 2 and 4 on JP6). N.B.,
- * 12v0 operation requires that the power supply actually supply 12v0
- * via pin 7 of JP7.
- *
- * CF Vcc:
- *
- * CF Vcc on BadgePAD 4 can be jumpered either for 3v3 (short pins 1
- * and 2 on JP10) or 5v0 (short pins 2 and 3 on JP10).
- *
- * Unfortunately there's no way programmatically to determine how a
- * given board is jumpered. This code assumes a default jumpering
- * as described below.
- *
- * If the defaults aren't correct, you may override them with a pcmv
- * setup argument: pcmv=<pcm vcc>,<pcm vpp>,<cf vcc>. The units are
- * tenths of volts; e.g. pcmv=33,120,50 indicates 3v3 PCM Vcc, 12v0
- * PCM Vpp, and 5v0 CF Vcc.

+ * intel-tpmi : Driver to enumerate TPMI features and create devices
+ *
+ * Copyright (c) 2023, Intel Corporation.
+ * All Rights Reserved.
+ *
+ * The TPMI (Topology Aware Register and PM Capsule Interface) provides a
+ * flexible, extendable and PCIe enumerable MMIO interface for PM features.
+ *
+ * For example Intel RAPL (Running Average Power Limit) provides a MMIO
+ * interface using TPMI. This has advantage over traditional MSR
+ * (Model Specific Register) interface, where a thread needs to be scheduled
+ * on the target CPU to read or write. Also the RAPL features vary between
+ * CPU models, and hence lot of model specific code. Here TPMI provides an
+ * architectural interface by providing hierarchical tables and fields,
+ * which will not need any model specific implementation.
+ *
+ * The TPMI interface uses a PCI VSEC structure to expose the location of
+ * MMIO region.
+ *
+ * This VSEC structure is present in the PCI configuration space of the
+ * Intel Out-of-Band (OOB) device, which is handled by the Intel VSEC
+ * driver. The Intel VSEC driver parses VSEC structures present in the PCI
+ * configuration space of the given device and creates an auxiliary device
+ * object for each of them. In particular, it creates an auxiliary device
+ * object representing TPMI that can be bound by an auxiliary driver.
+ *
+ * This TPMI driver will bind to the TPMI auxiliary device object created
+ * by the Intel VSEC driver.
+ *
+ * The TPMI specification defines a PFS (PM Feature Structure) table.
+ * This table is present in the TPMI MMIO region. The starting address
+ * of PFS is derived from the tBIR (Bar Indicator Register) and "Address"
+ * field from the VSEC header.
+ *
+ * Each TPMI PM feature has one entry in the PFS with a unique TPMI
+ * ID and its access details. The TPMI driver creates device nodes
+ * for the supported PM features.
+ *
+ * The names of the devices created by the TPMI driver start with the
+ * "intel_vsec.tpmi-" prefix which is followed by a specific name of the
+ * given PM feature (for example, "intel_vsec.tpmi-rapl.0").
+ *
+ * The device nodes are create by using interface "intel_vsec_add_aux()"
+ * provided by the Intel VSEC driver.

- * The stk webcam laptop module is mounted upside down in some laptops :(
- *
- * Some background information (thanks to Hans de Goede for providing this):
- *
- * 1) Once upon a time the stkwebcam driver was written
- *
- * 2) The webcam in question was used mostly in Asus laptop models, including
- * the laptop of the original author of the driver, and in these models, in
- * typical Asus fashion (see the long long list for uvc cams inside v4l-utils),
- * they mounted the webcam-module the wrong way up. So the hflip and vflip
- * module options were given a default value of 1 (the correct value for
- * upside down mounted models)
- *
- * 3) Years later I got a bug report from a user with a laptop with stkwebcam,
- * where the module was actually mounted the right way up, and thus showed
- * upside down under Linux. So now I was facing the choice of 2 options:
- *
- * a) Add a not-upside-down list to stkwebcam, which overrules the default.
- *
- * b) Do it like all the other drivers do, and make the default right for
- * cams mounted the proper way and add an upside-down model list, with
- * models where we need to flip-by-default.
- *
- * Despite knowing that going b) would cause a period of pain where we were
- * building the table I opted to go for option b), since a) is just too ugly,
- * and worse different from how every other driver does it leading to
- * confusion in the long run. This change was made in kernel 3.6.
- *
- * So for any user report about upside-down images since kernel 3.6 ask them
- * to provide the output of 'sudo dmidecode' so the laptop can be added in
- * the table below.

-This is one of the few drivers still not using the vb2
-framework, so this driver is now deprecated with the intent of
-removing it altogether by the beginning of 2023.
-
-In order to keep this driver it has to be converted to vb2.

- * Driver name : VPFE Capture driver
- * VPFE Capture driver allows applications to capture and stream video
- * frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
- * TVP5146 or Raw Bayer RGB image data from an image sensor
- * such as Microns' MT9T001, MT9T031 etc.
- *
- * These SoCs have, in common, a Video Processing Subsystem (VPSS) that
- * consists of a Video Processing Front End (VPFE) for capturing
- * video/raw image data and Video Processing Back End (VPBE) for displaying
- * YUV data through an in-built analog encoder or Digital LCD port. This
- * driver is for capture through VPFE. A typical EVM using these SoCs have
- * following high level configuration.
- *

- * V |
- * SDRAM |

- * SDRAM
- * The data flow happens from a decoder connected to the VPFE over a
- * YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
- * and to the input of VPFE through an optional MUX (if more inputs are
- * to be interfaced on the EVM). The input data is first passed through
- * CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
- * does very little or no processing on YUV data and does pre-process Raw
- * Bayer RGB data through modules such as Defect Pixel Correction (DFC)
- * Color Space Conversion (CSC), data gain/offset etc. After this, data
- * can be written to SDRAM or can be connected to the image processing
- * block such as IPIPE (on DM355 only).
- *
- * Features supported
- * - MMAP IO
- * - Capture using TVP5146 over BT.656
- * - support for interfacing decoders using sub device model
- * - Work with DM355 or DM6446 CCDC to do Raw Bayer RGB/YUV
- * data capture to SDRAM.
- * TODO list
- * - Support multiple REQBUF after open
- * - Support for de-allocating buffers through REQBUF
- * - Support for Raw Bayer RGB capture
- * - Support for chaining Image Processor
- * - Support for static allocation of buffers
- * - Support for USERPTR IO
- * - Support for STREAMON before QBUF
- * - Support for control ioctls
