+ * ACPICA policy for new _OSI strings:
+ *
+ * It is the stated policy of ACPICA that new _OSI strings will be integrated
+ * into this module as soon as possible after they are defined. It is strongly
+ * recommended that all ACPICA hosts mirror this policy and integrate any
+ * changes to this module as soon as possible. There are several historical
+ * reasons behind this policy:
+ *
+ * 1) New BIOSs tend to test only the case where the host responds TRUE to
+ *    the latest version of Windows, which would respond to the latest/newest
+ *    _OSI string. Not responding TRUE to the latest version of Windows will
+ *    risk executing untested code paths throughout the DSDT and SSDTs.
+ *
+ * 2) If a new _OSI string is recognized only after a significant delay, this
+ *    has the potential to cause problems on existing working machines because
+ *    of the possibility that a new and different path through the ASL code
+ *    will be executed.
+ *
+ * 3) New _OSI strings are tending to come out about once per year. A delay
+ *    in recognizing a new string for a significant amount of time risks the
+ *    release of another string which only compounds the initial problem.
+ *

+ * xgene_ahci_do_hardreset - Issue the actual COMRESET
+ * @link: link to reset
+ * @deadline: deadline jiffies for the operation
+ * @online: Return value to indicate if device online
+ *
+ * Due to the limitation of the hardware PHY, a difference set of setting is
+ * required for each supported disk speed - Gen3 (6.0Gbps), Gen2 (3.0Gbps),
+ * and Gen1 (1.5Gbps). Otherwise during long IO stress test, the PHY will
+ * report disparity error and etc. In addition, during COMRESET, there can
+ * be error reported in the register PORT_SCR_ERR. For SERR_DISPARITY and
+ * SERR_10B_8B_ERR, the PHY receiver line must be reseted. The following
+ * algorithm is followed to proper configure the hardware PHY during COMRESET:
+ *
+ * Alg Part 1:
+ * 1. Start the PHY at Gen3 speed (default setting)
+ * 2. Issue the COMRESET
+ * 3. If no link, go to Alg Part 3
+ * 4. If link up, determine if the negotiated speed matches the PHY
+ *    configured speed
+ * 5. If they matched, go to Alg Part 2
+ * 6. If they do not matched and first time, configure the PHY for the linked
+ *    up disk speed and repeat step 2
+ * 7. Go to Alg Part 2
+ *
+ * Alg Part 2:
+ * 1. On link up, if there are any SERR_DISPARITY and SERR_10B_8B_ERR error
+ *    reported in the register PORT_SCR_ERR, then reset the PHY receiver line
+ * 2. Go to Alg Part 3
+ *
+ * Alg Part 3:
+ * 1. Clear any pending from register PORT_SCR_ERR.
+ *
+ * NOTE: For the initial version, we will NOT support Gen1/Gen2. In addition
+ *       and until the underlying PHY supports an method to reset the receiver
+ *       line, on detection of SERR_DISPARITY or SERR_10B_8B_ERR errors,
+ *       an warning message will be printed.

+ * Each clock can have zero, one, or two dividers which change the

+ * variable.  If there are two dividers, they are the "pre-divider"
+ * and the "regular" or "downstream" divider.  If there is only one,
+ * there is no pre-divider.
+ *
+ * A fixed divider is any non-zero (positive) value, and it
+ * indicates how the input rate is affected by the divider.
+ *
+ * The value of a variable divider is maintained in a sub-field of a
+ * 32-bit divider register.  The position of the field in the
+ * register is defined by its offset and width.  The value recorded
+ * in this field is always 1 less than the value it represents.
+ *
+ * In addition, a variable divider can indicate that some subset
+ * of its bits represent a "fractional" part of the divider.  Such
+ * bits comprise the low-order portion of the divider field, and can
+ * be viewed as representing the portion of the divider that lies to
+ * the right of the decimal point.  Most variable dividers have zero
+ * fractional bits.  Variable dividers with non-zero fraction width
+ * still record a value 1 less than the value they represent; the
+ * added 1 does *not* affect the low-order bit in this case, it
+ * affects the bits above the fractional part only.  (Often in this
+ * code a divider field value is distinguished from the value it
+ * represents by referring to the latter as a "divisor".)
+ *
+ * In order to avoid dealing with fractions, divider arithmetic is
+ * performed using "scaled" values.  A scaled value is one that's
+ * been left-shifted by the fractional width of a divider.  Dividing
+ * a scaled value by a scaled divisor produces the desired quotient
+ * without loss of precision and without any other special handling
+ * for fractions.
+ *
+ * The recorded value of a variable divider can be modified.  To
+ * modify either divider (or both), a clock must be enabled (i.e.,
+ * using its gate).  In addition, a trigger register (described

+ * To keep it simple, let the GMAC use either the MII TX clock for MII mode,
+ * and its internal TX clock for GMII and RGMII modes. The GMAC driver should

+ * Only the GMAC should use this clock. Altering the clock so that it doesn't

+* Comments about DRXDAP_MAX_WCHUNKSIZE in single or multi master mode and
+* in combination with short and long addressing format. All text below
+* assumes long addressing format. The table also includes information
+* for short ADDRessing format.
+*
+* In single master mode, data can be written by sending the register address
+* first, then two or four bytes of data in the next packet.
+* Because the device address plus a register address equals five bytes,
+* the mimimum chunk size must be five.
+* If ten-bit I2C device addresses are used, the minimum chunk size must be six,
+* because the I2C device address will then occupy two bytes when writing.
+*
+* Data in single master mode is transferred as follows:
+* <S> <devW>  a0  a1  a2  a3  <P>
+* <S> <devW>  d0  d1 [d2  d3] <P>
+* ..
+* or
+* ..
+* <S> <devW>  a0  a1  a2  a3  <P>
+* <S> <devR> --- <P>
+*
+* In multi-master mode, the data must immediately follow the address (an I2C
+* stop resets the internal address), and hence the minimum chunk size is
+* 1 <I2C address> + 4 (register address) + 2 (data to send) = 7 bytes (8 if
+* 10-bit I2C device addresses are used).

+   Implementation notes.
+
+   NTSC/FM AGCs
+
+      Four AGCs are used for NTSC:
+      (1) RF (used to attenuate the input signal in case of to much power)
+      (2) IF (used to attenuate the input signal in case of to much power)
+      (3) Video AGC (used to amplify the output signal in case input to low)
+      (4) SIF AGC (used to amplify the output signal in case input to low)
+
+      Video AGC is coupled to RF and IF. SIF AGC is not coupled. It is assumed
+      that the coupling between Video AGC and the RF and IF AGCs also works in
+      favor of the SIF AGC.
+
+      Three AGCs are used for FM:
+      (1) RF (used to attenuate the input signal in case of to much power)
+      (2) IF (used to attenuate the input signal in case of to much power)
+      (3) SIF AGC (used to amplify the output signal in case input to low)
+
+      The SIF AGC is now coupled to the RF/IF AGCs.
+      The SIF AGC is needed for both SIF ouput and the internal SIF signal to
+      the AUD block.
+
+      RF and IF AGCs DACs are part of AFE, Video and SIF AGC DACs are part of
+      the ATV block. The AGC control algorithms are all implemented in
+      microcode.
+
+   ATV SETTINGS
+
+      (Shadow settings will not be used for now, they will be implemented
+       later on because of the schedule)
+
+      Several HW/SCU "settings" can be used for ATV. The standard selection
+      will reset most of these settings. To avoid that the end user apllication
+      has to perform these settings each time the ATV or FM standards is
+      selected the driver will shadow these settings. This enables the end user
+      to perform the settings only once after a drx_open(). The driver must
+      write the shadow settings to HW/SCU incase:
+	 ( setstandard FM/ATV) ||
+	 ( settings have changed && FM/ATV standard is active)
+      The shadow settings will be stored in the device specific data container.
+      A set of flags will be defined to flag changes in shadow settings.
+      A routine will be implemented to write all changed shadow settings to
+      HW/SCU.
+
+      The "settings" will consist of: AGC settings, filter settings etc.
+
+      Disadvantage of use of shadow settings:
+      Direct changes in HW/SCU registers will not be reflected in the
+      shadow settings and these changes will be overwritten during a next
+      update. This can happen during evaluation. This will not be a problem
+      for normal customer usage.

+ * Read-only block devices on top of UBI volumes
+ *
+ * A simple implementation to allow a block device to be layered on top of a
+ * UBI volume. The implementation is provided by creating a static 1-to-1
+ * mapping between the block device and the UBI volume.
+ *
+ * The addressed byte is obtained from the addressed block sector, which is
+ * mapped linearly into the corresponding LEB:
+ *
+ *   LEB number = addressed byte / LEB size
+ *
+ * This feature is compiled in the UBI core, and adds a 'block' parameter
+ * to allow early creation of block devices on top of UBI volumes. Runtime
+ * block creation/removal for UBI volumes is provided through two UBI ioctls:
+ * UBI_IOCVOLCRBLK and UBI_IOCVOLRMBLK.

+/* There are 3 ways the host can communicate with the trf7970a:
+ * parallel mode, SPI with Slave Select (SS) mode, and SPI without
+ * SS mode.  The driver only supports the two SPI modes.
+ *
+ * The trf7970a is very timing sensitive and the VIN, EN2, and EN
+ * pins must asserted in that order and with specific delays in between.
+ * The delays used in the driver were provided by TI and have been
+ * confirmed to work with this driver.
+ *
+ * Timeouts are implemented using the delayed workqueue kernel facility.
+ * Timeouts are required so things don't hang when there is no response
+ * from the trf7970a (or tag).  Using this mechanism creates a race with
+ * interrupts, however.  That is, an interrupt and a timeout could occur
+ * closely enough together that one is blocked by the mutex while the other
+ * executes.  When the timeout handler executes first and blocks the
+ * interrupt handler, it will eventually set the state to IDLE so the
+ * interrupt handler will check the state and exit with no harm done.
+ * When the interrupt handler executes first and blocks the timeout handler,
+ * the cancel_delayed_work() call will know that it didn't cancel the
+ * work item (i.e., timeout) and will return zero.  That return code is
+ * used by the timer handler to indicate that it should ignore the timeout
+ * once its unblocked.
+ *
+ * Aborting an active command isn't as simple as it seems because the only
+ * way to abort a command that's already been sent to the tag is so turn
+ * off power to the tag.  If we do that, though, we'd have to go through
+ * the entire anticollision procedure again but the digital layer doesn't
+ * support that.  So, if an abort is received before trf7970a_in_send_cmd()
+ * has sent the command to the tag, it simply returns -ECANCELED.  If the
+ * command has already been sent to the tag, then the driver continues
+ * normally and recieves the response data (or error) but just before
+ * sending the data upstream, it frees the rx_skb and sends -ECANCELED
+ * upstream instead.  If the command failed, that error will be sent
+ * upstream.
+ *
+ * When recieving data from a tag and the interrupt status register has
+ * only the SRX bit set, it means that all of the data has been received
+ * (once what's in the fifo has been read).  However, depending on timing
+ * an interrupt status with only the SRX bit set may not be recived.  In
+ * those cases, the timeout mechanism is used to wait 5 ms in case more
+ * data arrives.  After 5 ms, it is assumed that all of the data has been
+ * received and the accumulated rx data is sent upstream.  The
+ * 'TRF7970A_ST_WAIT_FOR_RX_DATA_CONT' state is used for this purpose
+ * (i.e., it indicates that some data has been received but we're not sure
+ * if there is more coming so a timeout in this state means all data has
+ * been received and there isn't an error).  The delay is 5 ms since delays
+ * over 2 ms have been observed during testing (a little extra just in case).
+ *
+ * Type 2 write and sector select commands respond with a 4-bit ACK or NACK.
+ * Having only 4 bits in the FIFO won't normally generate an interrupt so
+ * driver enables the '4_bit_RX' bit of the Special Functions register 1
+ * to cause an interrupt in that case.  Leaving that bit for a read command
+ * messes up the data returned so it is only enabled when the framing is
+ * 'NFC_DIGITAL_FRAMING_NFCA_T2T' and the command is not a read command.
+ * Unfortunately, that means that the driver has to peek into tx frames
+ * when the framing is 'NFC_DIGITAL_FRAMING_NFCA_T2T'.  This is done by
+ * the trf7970a_per_cmd_config() routine.
+ *
+ * ISO/IEC 15693 frames specify whether to use single or double sub-carrier
+ * frequencies and whether to use low or high data rates in the flags byte
+ * of the frame.  This means that the driver has to peek at all 15693 frames
+ * to determine what speed to set the communication to.  In addition, write
+ * and lock commands use the OPTION flag to indicate that an EOF must be
+ * sent to the tag before it will send its response.  So the driver has to
+ * examine all frames for that reason too.
+ *
+ * It is unclear how long to wait before sending the EOF.  According to the
+ * Note under Table 1-1 in section 1.6 of
+ * http://www.ti.com/lit/ug/scbu011/scbu011.pdf, that wait should be at least
+ * 10 ms for TI Tag-it HF-I tags; however testing has shown that is not long
+ * enough.  For this reason, the driver waits 20 ms which seems to work
+ * reliably.

+ * The APM X-Gene PHY consists of two PLL clock macro's (CMU) and lanes.
+ * The first PLL clock macro is used for internal reference clock. The second
+ * PLL clock macro is used to generate the clock for the PHY. This driver
+ * configures the first PLL CMU, the second PLL CMU, and programs the PHY to
+ * operate according to the mode of operation. The first PLL CMU is only
+ * required if internal clock is enabled.
+ *
+ * Logical Layer Out Of HW module units:
+ *
+ * -----------------
+ * | Internal      |    |------|
+ * | Ref PLL CMU   |----|      |     -------------    ---------
+ * ------------ ----    | MUX  |-----|PHY PLL CMU|----| Serdes|
+ *                      |      |     |           |    ---------
+ * External Clock ------|      |     -------------
+ *                      |------|
+ *
+ * The Ref PLL CMU CSR (Configuration System Registers) is accessed
+ * indirectly from the SDS offset at 0x2000. It is only required for
+ * internal reference clock.
+ * The PHY PLL CMU CSR is accessed indirectly from the SDS offset at 0x0000.
+ * The Serdes CSR is accessed indirectly from the SDS offset at 0x0400.
+ *
+ * The Ref PLL CMU can be located within the same PHY IP or outside the PHY IP
+ * due to shared Ref PLL CMU. For PHY with Ref PLL CMU shared with another IP,
+ * it is located outside the PHY IP. This is the case for the PHY located
+ * at 0x1f23a000 (SATA Port 4/5). For such PHY, another resource is required
+ * to located the SDS/Ref PLL CMU module and its clock for that IP enabled.
+ *
+ * Currently, this driver only supports Gen3 SATA mode with external clock.

+/*
+ *      In the original out of kernel Digi dgap driver, firmware
+ *      loading was done via user land to driver handshaking.
+ *
+ *      For cards that support a concentrator (port expander),
+ *      I believe the concentrator its self told the card which
+ *      concentrator is actually attached and then that info
+ *      was used to tell user land which concentrator firmware
+ *      image was to be downloaded. I think even the BIOS or
+ *      FEP images required could change with the connection
+ *      of a particular concentrator.
+ *
+ *      Since I have no access to any of these cards or
+ *      concentrators, I cannot put the correct concentrator
+ *      firmware file names into the firmware_info structure
+ *      as is now done for the BIOS and FEP images.
+ *
+ *      I think, but am not certain, that the cards supporting
+ *      concentrators will function without them. So support
+ *      of these cards has been left in this driver.
+ *
+ *      In order to fully support those cards, they would
+ *      either have to be acquired for dissection or maybe
+ *      Digi International could provide some assistance.

+Linux Driver Source for Xilinx FPGA firmware download

+TABLE OF CONTENTS.
+
+1.  SUMMARY
+2.  BACKGROUND
+3.  DESIGN
+4.  HOW TO USE
+5.  REFERENCE
+
+1. SUMMARY
+
+	- Download Xilinx FPGA firmware
+	- This module downloads Xilinx FPGA firmware using gpio pins.
+
+2. BACKGROUND
+
+	An FPGA (Field Programmable Gate Array) is a programmable hardware that is
+	used in various applications. Hardware design needs to programmed through
+	a dedicated device or CPU assisted way (serial or parallel).
+	This driver provides a way to download FPGA firmware.
+
+3. DESIGN
+
+	- load Xilinx FPGA bitstream format[1] firmware image file using 
+	  kernel firmware framework, request_firmware()
+	- program the Xilinx FPGA using SelectMAP (parallel) mode [2]
+	- FPGA prgram is done by gpio based bit-banging, as an example
+	- platform independent file: gs_fpgaboot.c
+	- platform dependent file: io.c
+	
+
+4. HOW TO USE
+
+	$ insmod gs_fpga.ko file="xlinx_fpga_top_bitstream.bit"
+	$ rmmod gs_fpga
+
+5. USE CASE (from a mailing list discussion with Greg)
+
+	a. As a FPGA development support tool,
+	During FPGA firmware development, you need to download a new FPGA
+	image frequently.
+	You would do that with a dedicated JTAG, which usually a limited
+	resource in the lab.
+	However, if you use my driver, you don't have to have a dedicated JTAG.
+	This is a real gain :)
+
+	b. For the FPGA that runs without config after the download, which
+	doesn't talk to any of Linux interfaces (such as PCIE).
+
+	We download FPGA firmware from user triggered or some other way, and that's it.
+	Since that FPGA runs on its own, it doesn't require a linux driver
+	after the download.
+
+	c. For the FPGA that requires config after the download, which talk to
+	any of linux interfaces (such as PCIE)
+
+	Then, this type of FPGA config can be put into device tree and have a
+	separate driver (pcie or others), then THAT driver calls my driver to
+	download FPGA firmware during the Linux boot, the take over the device
+	through the interface.
+

 TODO:
 - get DRM Maintainer review for this code
-- Wait for common display framework to hit mainline and update the IPU
-  driver to use it. This will most probably make changes to the devicetree
-  bindings necessary.
-- Factor out more code to common helper functions
 - decide where to put the base driver. It is not specific to a subsystem
   and would be used by DRM/KMS and media/V4L2
 
 Missing features (not necessarily for moving out of staging):
 
-- Add i.MX6 HDMI support
 - Add support for IC (Image converter)
 - Add support for CSI (CMOS Sensor interface)
 - Add support for VDIC (Video Deinterlacer)

+
+Since none of these devices can function without having a valid
+address, the way this should work is that we should not register the
+HCI device when probing the platform device.
+    
+The HCI device should be registered once a valid address has been
+written into the sysfs file. I do not want to play the tricks with
+bringing up the device without a valid address.

+hdev->setup does. It gets executed once.

+
+Overview
+
+This document describes the driver set for Unisys Secure Partitioning (s-Par®).
+
+s-Par is firmware that provides hardware partitioning capabilities for
+splitting large-scale Intel x86 servers into multiple isolated
+partitions. s-Par provides a set of para-virtualized device drivers to
+allow guest partitions on the same server to share devices that would
+normally be unsharable; specifically, PCI network interfaces and host
+bus adapters that do not support shared access via SR-IOV. The shared
+device is owned and managed by a small, single-purpose service
+partition, which communicates with each guest partition sharing that
+device through an area of shared memory called a channel. Additional
+drivers provide support interfaces for communicating with s-Par
+services, logging and diagnostics, and accessing the Linux console
+from the s-Par user interface.
+
+The driver stack consists of a set of support modules, a set of bus
+modules, and a set of device driver modules. The support modules
+handle a number of common functions across each of the other
+drivers. The bus modules provide organization for the device driver
+modules, which provide the shared device functionality.
+
+These drivers are for the Unisys virtual PCI hardware model where the
+hypervisor need not intervene (other than normal interrupt handling)
+in the interactions between the client drivers and the virtual adapter
+firmware in the adapter service partition.
+
+Driver Descriptions
+
+Device Modules
+
+The modules in this section handle shared devices and the virtual
+buses required to support them. These modules use functions in and
+depend on the modules described in the support modules section.
+
+visorchipset
+
+The visorchipset module receives device creation and destruction
+events from the Command service partition of s-Par, as well as
+controlling registration of shared device drivers with the s-Par
+driver core. The events received are used to populate other s-Par
+modules with their assigned shared devices. Visorchipset is required
+for shared device drivers to function properly. Visorchipset also
+stores information for handling dump disk device creation during
+kdump.
+
+In operation, the visorchipset module processes device creation and
+destruction messages sent by s-Par's Command service partition through
+a channel. These messages result in creation (or destruction) of each
+virtual bus and virtual device. Each bus and device is also associated
+with a communication channel, which is used to communicate with one or
+more IO service partitions to perform device IO on behalf of the
+guest.
+
+virthba
+
+The virthba module provides access to a shared SCSI host bus adapter
+and one or more disk devices, by proxying SCSI commands between the
+guest and the service partition that owns the shared SCSI adapter,
+using a channel between the guest and the service partition. The disks
+that appear on the shared bus are defined by the s-Par configuration
+and enforced by the service partition, while the guest driver handles
+sending commands and handling responses. Each disk is shared as a
+whole to a guest. Sharing the bus adapter in this way provides
+resiliency; should the device encounter an error, only the service
+partition is rebooted, and the device is reinitialized. This allows
+guests to continue running and to recover from the error.
+
+virtnic
+
+The virtnic module provides a paravirtualized network interface to a
+guest by proxying buffer information between the guest and the service
+partition that owns the shared network interface, using a channel
+between the guest and the service partition. The connectivity of this
+interface with the shared interface and possibly other guest
+partitions is defined by the s-Par configuration and enforced by the
+service partition; the guest driver handles communication and link
+status.
+
+visorserial
+
+The visorserial module allows the console of the linux guest to be
+accessed via the s-Par console serial channel. It creates devices in
+/dev/visorserialclientX which behave like a serial terminal and are
+connected to the diagnostics system in s-Par. By assigning a getty to
+the terminal in the guest, a user could log into and access the guest
+from the s-Par diagnostics SWITCH RUN terminal.
+
+visorbus
+
+The visorbus module handles the bus functions for most functional
+drivers except visorserial, visordiag, virthba, and virtnic. It
+maintains the sysfs subtree /sys/devices/visorbus*/. It is responsible
+for device creation and destruction of the devices on its bus.
+
+visorclientbus
+
+The visorclientbus module forwards the bus functions for virthba, and
+virtnic to the virtpci driver.
+
+virtpci
+
+The virtpci module handles the bus functions for virthba, and virtnic.
+
+s-Par Integration Modules
+
+The modules in this section provide integration with s-Par guest
+partition services like diagnostics and remote desktop. These modules
+depend on functions in the modules described in the support modules
+section.
+
+visorvideoclient
+
+The visorvideoclient module provides functionality for video support
+for the Unisys s-Par Partition Desktop application. The guest OS must
+also have the UEFI GOP protocol enabled for the partition desktop to
+function.  visorconinclient The visorconinclient module provides
+keyboard and mouse support for the Unisys s-Par Partition Desktop
+application.
+
+sparstop
+
+The sparstop module handles requests from the Unisys s-Par platform to
+shutdown the linux guest. It allows a program on the guest to perform
+clean-up functions on the guest before the guest is shut down or
+rebooted using ACPI.
+
+visordiag
+
+This driver provides the ability for the guest to write information
+into the s-Par diagnostics subsystem. It creates a set of devices
+named /dev/visordiag.X which can be written to by the guest to add
+text to the s-Par system log.
+
+Support Modules
+
+The modules described in this section provide functions and
+abstractions to support the modules described in the previous
+sections, to avoid having duplicated functionality.
+
+visornoop
+
+The visornoop module is a placeholder that responds to device
+create/destroy messages that are currently not in use by linux guests.
+
+visoruislib
+
+The visoruislib module is a support library, used to handle requests
+from virtpci.
+
+visorchannelstub
+
+The visorchannelstub module provides support routines for storing and
+retrieving data from a channel.
+
+visorchannel
+
+The visorchannel module is a support library that abstracts reading
+and writing a channel in memory.
+
+visorutil
+
+The visorutil module is a support library required by all other s-Par
+driver modules. Among its features it abstracts reading, writing, and
+manipulating a block of memory.
+
+Minimum Required Driver Set
+
+The drivers required to boot a Linux guest are visorchipset, visorbus,
+visorvideoclient, visorconinclient, visoruislib, visorchannelstub,
+visorchannel, and visorutil. The other drivers are required by the
+product configurations that are currently being marketed.

+ s-Par Proc Entries
+This document describes the proc entries created by the Unisys s-Par modules.
+
+Support Module Entries
+These entries are provided primarily for debugging.
+
+/proc/uislib/info: This entry contains debugging information for the
+uislib module, including bus information and memory usage.
+
+/proc/visorchipset/controlvm: This directory contains debugging
+entries for the controlvm channel used by visorchipset.
+
+/proc/uislib/platform: This entry is used to display the platform
+number this node is in the system. For some guests, this may be
+invalid.
+
+/proc/visorchipset/chipsetready: This entry is written to by scripts
+to signify that any user level activity has been completed before the
+guest can be considered running and is shown as running in the s-Par
+UI.
+
+Device Entries
+These entries provide status of the devices shared by a service partition.
+
+/proc/uislib/vbus: this is a directory containing entries for each
+virtual bus. Each numbered sub-directory contains an info entry, which
+describes the devices that appear on that bus.
+
+/proc/uislib/cycles_before_wait: This entry is used to tune
+performance, by setting the number of cycles we wait before going idle
+when in polling mode. A longer time will reduce message latency but
+spend more processing time polling.
+
+/proc/uislib/smart_wakeup: This entry is used to tune performance, by
+enabling or disabling smart wakeup.
+
+/proc/virthba/info: This entry contains debugging information for the
+virthba module, including interrupt information and memory usage.
+
+/proc/virthba/enable_ints: This entry controls interrupt use by the
+virthba module. Writing a 0 to this entry will disable interrupts.
+
+/proc/virtnic/info: This entry contains debugging information for the
+virtnic module, including interrupt information, send and receive
+counts, and other device information.
+
+/proc/virtnic/ethX: This is a directory containing entries for each
+virtual NIC. Each named subdirectory contains two entries,
+clientstring and zone.
+
+/proc/virtpci/info: This entry contains debugging information for the
+virtpci module, including virtual PCI bus information and device
+locations.
+
+/proc/virtnic/enable_ints: This entry controls interrupt use by the
+virtnic module. Writing a 0 to this entry will disable interrupts.
+
+Visorconinclient, visordiag, visornoop, visorserialclient, and
+visorvideoclient Entries
+
+The entries in proc for these modules all follow the same
+pattern. Each module has its own proc directory with the same name,
+e.g. visordiag presents a /proc/visordiag directory. Inside of the
+module's directory are a device directory, which contains one numbered
+directory for each device provided by that module. Each device has a
+diag entry that presents the device number and visorbus name for that
+device. The module directory also has a driver/diag entry, which
+reports the corresponding s-Par version number of the driver.
+
+Automated Installation Entries
+
+These entries are used to pass information between the s-Par platform
+and the Linux-based installation and recovery tool. These values are
+read/write, however, the guest can only reset them to 0, or report an
+error status through the installer entry. The values are only set via
+s-Par's firmware interface, to help prevent accidentally booting into
+the tool.
+
+/proc/visorchipset/boottotool: This entry instructs s-Par that the
+next reboot will launch the installation and recovery tool. If set to
+0, the next boot will happen according to the UEFI boot manager
+settings.
+
+/proc/visorchipset/toolaction: This entry indicates the installation
+and recovery tool mode requested for the next boot.
+
+/proc/visorchipset/installer: this entry is used by the installation
+and recovery tool to pass status and result information back to the
+s-Par firmware.
+
+/proc/visorchipset/partition: This directory contains the guest
+partition configuration data for each virtual bus, for use during
+installation and at runtime for s-Par service partitions.

+ * We need a radix tree for mapping physical addresses of TRBs to which stream

+ * event data TRB, but that doesn't help us for the cancellation case, since the
+ * endpoint may stop before it reaches that event data TRB.
+ *
+ * The radix tree maps the upper portion of the TRB DMA address to a ring
+ * segment that has the same upper portion of DMA addresses.  For example, say I
+ * have segments of size 1KB, that are always 1KB aligned.  A segment may
+ * start at 0x10c91000 and end at 0x10c913f0.  If I use the upper 10 bits, the
+ * key to the stream ID is 0x43244.  I can use the DMA address of the TRB to
+ * pass the radix tree a key to get the right stream ID:
+ *
+ *	0x10c90fff >> 10 = 0x43243
+ *	0x10c912c0 >> 10 = 0x43244
+ *	0x10c91400 >> 10 = 0x43245
+ *
+ * Obviously, only those TRBs with DMA addresses that are within the segment
+ * will make the radix tree return the stream ID for that ring.
+ *
+ * Caveats for the radix tree:
+ *
+ * The radix tree uses an unsigned long as a key pair.  On 32-bit systems, an
+ * unsigned long will be 32-bits; on a 64-bit system an unsigned long will be
+ * 64-bits.  Since we only request 32-bit DMA addresses, we can use that as the
+ * key on 32-bit or 64-bit systems (it would also be fine if we asked for 64-bit
+ * PCI DMA addresses on a 64-bit system).  There might be a problem on 32-bit
+ * extended systems (where the DMA address can be bigger than 32-bits),
+ * if we allow the PCI dma mask to be bigger than 32-bits.  So don't do that.

- * event data TRB, but that doesn't help us for the cancellation case, since the
- * endpoint may stop before it reaches that event data TRB.
- *
- * The radix tree maps the upper portion of the TRB DMA address to a ring
- * segment that has the same upper portion of DMA addresses.  For example, say I
- * have segments of size 1KB, that are always 64-byte aligned.  A segment may
- * start at 0x10c91000 and end at 0x10c913f0.  If I use the upper 10 bits, the
- * key to the stream ID is 0x43244.  I can use the DMA address of the TRB to
- * pass the radix tree a key to get the right stream ID:
- *
- * 	0x10c90fff >> 10 = 0x43243
- * 	0x10c912c0 >> 10 = 0x43244
- * 	0x10c91400 >> 10 = 0x43245
- *
- * Obviously, only those TRBs with DMA addresses that are within the segment
- * will make the radix tree return the stream ID for that ring.
- *
- * Caveats for the radix tree:
- *
- * The radix tree uses an unsigned long as a key pair.  On 32-bit systems, an
- * unsigned long will be 32-bits; on a 64-bit system an unsigned long will be
- * 64-bits.  Since we only request 32-bit DMA addresses, we can use that as the
- * key on 32-bit or 64-bit systems (it would also be fine if we asked for 64-bit
- * PCI DMA addresses on a 64-bit system).  There might be a problem on 32-bit
- * extended systems (where the DMA address can be bigger than 32-bits),
- * if we allow the PCI dma mask to be bigger than 32-bits.  So don't do that.

+	 *
+	 * The v2 version of this interface intends to be more deterministic.
+	 * Unmap requests must fully cover previous mappings.  Multiple
+	 * mappings may still be unmaped by specifying large ranges, but there
+	 * must not be any previous mappings bisected by the range.  An error
