From 5aa83a4c0a1568257ff7e249d39af64f75978b97 Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Thu, 12 May 2005 22:27:35 -0400 Subject: [PATCH] remove two obsolete net drivers The options FMV18X and SK_G16 do depend on the non-available CONFIG_OBSOLETE even in kernel 2.4 - IOW, the last time it was able to select them was in kernel 2.2 (or even before). Since it seems noone misses these drivers, this patch removes them.

FR Cisco LMI production-tested. Please apply to Linux 2.6. Thanks. Changes: - doc updates - added Cisco LMI support to Frame-Relay code - cleaned hdlc_fr.c a bit, removed some orphaned #defines etc. - fixed a problem with non-functional LMI in FR DCE mode. - changed diagnostic messages to better conform to FR standards - all protocols: information about carrier changes (DCD line) is now printed to kernel logs.

This removes that "detach_state" mechanism; net code shrink, as well as a per-device saving in the driver model and sysfs.

It is *not* supported to work with +common small CD-ROM changers, neither one-lun-per-slot SCSI changers +nor IDE drives. + +Userland tools available from here: + http://linux.bytesex.org/misc/changer.html + + +General Information +------------------- + +First some words about how changers work: A changer has 2 (possibly +more) SCSI ID's. One for the changer device which controls the robot, +and one for the device which actually reads and writes the data. The +later may be anything, a MOD, a CD-ROM, a tape or whatever. For the +changer device this is a "don't care", he *only* shuffles around the +media, nothing else. + + +The SCSI changer model is complex, compared to - for example - IDE-CD +changers. But it allows to handle nearly all possible cases. It knows +4 different types of changer elements: + + media transport - this one shuffles around the media, i.e. the + transport arm. Also known as "picker". + storage - a slot which can hold a media. + import/export - the same as above, but is accessable from outside, + i.e. there the operator (you !) can use this to + fill in and remove media from the changer. + Sometimes named "mailslot". + data transfer - this is the device which reads/writes, i.e. the + CD-ROM / Tape / whatever drive. + +None of these is limited to one: A huge Jukebox could have slots for +123 CD-ROM's, 5 CD-ROM readers (and therefore 6 SCSI ID's: the changer +and each CD-ROM) and 2 transport arms. No problem to handle. + + +How it is implemented +--------------------- + +I implemented the driver as character device driver with a NetBSD-like +ioctl interface. Just grabbed NetBSD's header file and one of the +other linux SCSI device drivers as starting point. The interface +should be source code compatible with NetBSD. So if there is any +software (anybody knows ???) which supports a BSDish changer driver, +it should work with this driver too. + +Over time a few more ioctls where added, volume tag support for example +wasn't covered by the NetBSD ioctl API. + + +Current State +------------- + +Support for more than one transport arm is not implemented yet (and +nobody asked for it so far...). + +I test and use the driver myself with a 35 slot cdrom jukebox from +Grundig. I got some reports telling it works ok with tape autoloaders +(Exabyte, HP and DEC). Some People use this driver with amanda. It +works fine with small (11 slots) and a huge (4 MOs, 88 slots) +magneto-optical Jukebox. Probably with lots of other changers too, most +(but not all :-) people mail me only if it does *not* work... + +I don't have any device lists, neither black-list nor white-list. Thus +it is quite useless to ask me whenever a specific device is supported or +not. In theory every changer device which supports the SCSI-2 media +changer command set should work out-of-the-box with this driver. If it +doesn't, it is a bug. Either within the driver or within the firmware +of the changer device. + + +Using it +-------- + +This is a character device with major number is 86, so use +"mknod /dev/sch0 c 86 0" to create the special file for the driver. + +If the module finds the changer, it prints some messages about the +device [ try "dmesg" if you don't see anything ] and should show up in +/proc/devices. If not.... some changers use ID ? / LUN 0 for the +device and ID ? / LUN 1 for the robot mechanism. But Linux does *not* +look for LUN's other than 0 as default, becauce there are to many +broken devices. So you can try: + + 1) echo "scsi add-single-device 0 0 ID 1" > /proc/scsi/scsi + (replace ID with the SCSI-ID of the device) + 2) boot the kernel with "max_scsi_luns=1" on the command line + (append="max_scsi_luns=1" in lilo.conf should do the trick) + + +Trouble? +-------- + +If you insmod the driver with "insmod debug=1", it will be verbose and +prints a lot of stuff to the syslog. Compiling the kernel with +CONFIG_SCSI_CONSTANTS=y improves the quality of the error messages alot +because the kernel will translate the error codes into human-readable +strings then. + +You can display these messages with the dmesg command (or check the +logfiles). If you email me some question becauce of a problem with the +driver, please include these messages. + + +Insmod options +-------------- + +debug=0/1 + Enable debug messages (see above, default: 0). + +verbose=0/1 + Be verbose (default: 1). + +init=0/1 + Send INITIALIZE ELEMENT STATUS command to the changer + at insmod time (default: 1). + +timeout_init= + timeout for the INITIALIZE ELEMENT STATUS command + (default: 3600). + +timeout_move= + timeout for all other commands (default: 120). + +dt_id=,,... +dt_lun=,,... + These two allow to specify the SCSI ID and LUN for the data + transfer elements. You likely don't need this as the jukebox + should provide this information. But some devices don't ... + +vendor_firsts= +vendor_counts= +vendor_labels= + These insmod options can be used to tell the driver that there + are some vendor-specific element types. Grundig for example + does this. Some jukeboxes have a printer to label fresh burned + CDs, which is addressed as element 0xc000 (type 5). To tell the + driver about this vendor-specific element, use this: + $ insmod ch \ + vendor_firsts=0xc000 \ + vendor_counts=1 \ + vendor_labels=printer + All three insmod options accept up to four comma-separated + values, this way you can configure the element types 5-8. + You likely need the SCSI specs for the device in question to + find the correct values as they are not covered by the SCSI-2 + standard. + + +Credits +------- + +I wrote this driver using the famous mailing-patches-around-the-world +method.

- - - - - Introduction - -This document outlines the interface between the Linux scsi mid level -and lower level drivers. Lower level drivers are variously called HBA -(host bus adapter) drivers, host drivers (HD) or pseudo adapter drivers. -The latter alludes to the fact that a lower level driver may be a -bridge to another IO subsystem (and the "ide-scsi" driver is an example -of this). There can be many lower level drivers active in a running -system, but only one per hardware type. For example, the aic7xxx driver -controls adaptec controllers based on the 7xxx chip series. Most lower -level drivers can control one or more scsi hosts (a.k.a. scsi initiators). - - -This document can been found in an ASCII text file in the linux kernel -source: Documentation/scsi/scsi_mid_low_api.txt . -It currently hold a little more information than this document. The -drivers/scsi/hosts.h and -drivers/scsi/scsi.h headers contain descriptions of members -of important structures for the scsi subsystem. - - - - - Driver structure - -Traditionally a lower level driver for the scsi subsystem has been -at least two files in the drivers/scsi directory. For example, a -driver called "xyz" has a header file "xyz.h" and a source file -"xyz.c". [Actually there is no good reason why this couldn't all -be in one file.] Some drivers that have been ported to several operating -systems (e.g. aic7xxx which has separate files for generic and -OS-specific code) have more than two files. Such drivers tend to have -their own directory under the drivers/scsi directory. - - -scsi_module.c is normally included at the end of a lower -level driver. For it to work a declaration like this is needed before -it is included: - - static Scsi_Host_Template driver_template = DRIVER_TEMPLATE; - /* DRIVER_TEMPLATE should contain pointers to supported interface - functions. Scsi_Host_Template is defined hosts.h */ - #include "scsi_module.c" - - - -The scsi_module.c assumes the name "driver_template" is appropriately -defined. It contains 2 functions: - - - init_this_scsi_driver() called during builtin and module driver - initialization: invokes mid level's scsi_register_host() - - - exit_this_scsi_driver() called during closedown: invokes - mid level's scsi_unregister_host() - - - - -When a new, lower level driver is being added to Linux, the following -files (all found in the drivers/scsi directory) will need some attention: -Makefile, Config.help and Config.in . It is probably best to look at what -an existing lower level driver does in this regard. - - - - - Interface Functions -!EDocumentation/scsi/scsi_mid_low_api.txt - - - - Locks - -Each Scsi_Host instance has a spin_lock called Scsi_Host::default_lock -which is initialized in scsi_register() [found in hosts.c]. Within the -same function the Scsi_Host::host_lock pointer is initialized to point -at default_lock with the scsi_assign_lock() function. Thereafter -lock and unlock operations performed by the mid level use the -Scsi_Host::host_lock pointer. - - -Lower level drivers can override the use of Scsi_Host::default_lock by -using scsi_assign_lock(). The earliest opportunity to do this would -be in the detect() function after it has invoked scsi_register(). It -could be replaced by a coarser grain lock (e.g. per driver) or a -lock of equal granularity (i.e. per host). Using finer grain locks -(e.g. per scsi device) may be possible by juggling locks in -queuecommand(). - - - - - Changes since lk 2.4 series - -io_request_lock has been replaced by several finer grained locks. The lock -relevant to lower level drivers is Scsi_Host::host_lock and there is one -per scsi host. - - -The older error handling mechanism has been removed. This means the -lower level interface functions abort() and reset() have been removed. - - -In the 2.4 series the scsi subsystem configuration descriptions were -aggregated with the configuration descriptions from all other Linux -subsystems in the Documentation/Configure.help file. In the 2.5 series, -the scsi subsystem now has its own (much smaller) drivers/scsi/Config.help -file. - - - - - Credits - -The following people have contributed to this document: - - -Mike Anderson andmike@us.ibm.com - - -James Bottomley James.Bottomley@steeleye.com - - -Patrick Mansfield patmans@us.ibm.com - - - - - -

Since the hotplug code is holding a spinlock at this point, we cannot take the cpuset semaphore, cpuset_sem, as would seem to be required either to update the tasks cpuset, or to scan up the nested cpuset chain, looking for the nearest cpuset ancestor that still has some CPUs that are online. So we just punt and blast the tasks cpus_allowed with all bits allowed. This reverts these lines of code to what they were before the cpuset patch. And it updates the cpuset Doc file, to match. The one known alternative to this that seems to work came from Dinakar Guniguntala, and required the hotplug code to take the cpuset_sem semaphore much earlier in its processing. So far as we know, the increased locking entanglement between cpusets and hot plug of this alternative approach is not worth doing in this case.

Because the design of ATI chipset follows intel HD Audio specification 1.0, the programming method is the same as that of intel HD Audio device exception one minor change which requires to enable snoop for DMA transport. There are 3 changes that have been made to hda_intel.c file. 1. Added device ID for ATI HD Audio device; 2. Increase maximum CODEC supported to 4; 3. Enable snoop during the driver initialization.

The patch includes the WM-codec initialization fix by Jaanus Kivistik . Since both AV-710 and AMP Audio2000 have the same SSID, initialize WM codecs as default for both devices. In case it breaks Audio2000, you can pass 'model=amp2000' option to avoid WM codec initialization.
