* [SCSI] Add Documentation and integrate into docbook buildRob Landley2008-01-1115-288/+411
| | | | | | | | | | | Add Documentation/DocBook/scsi_midlayer.tmpl, add to Makefile, and update lots of kerneldoc comments in drivers/scsi/*. Updated with comments from Stefan Richter, Stephen M.

* [SCSI] zfcp: Reduce flood on hba traceChristof Schmitt2008-01-111-6/+0
| | | | | | | | | | | | | | | Remove tracing for request with a "qualifier" field set in the response. The protocol status qualifier now contains measurement data for "good" commands, so this check would trace every response by default. The fix is to simply remove the "qual" tracing: The responses with an interesting status are also traced as "ferr" or "perr" and all responses can be traced as "norm" with a higher trace level.

* [SCSI] zfcp: Fix deadlock when adding invalid LUNChristof Schmitt2008-01-114-10/+0
| | | | | | | | | | | | | | | When adding an invalid LUN, there is a deadlock between the add via scsi_scan_target and the slave_destroy handler: The handler waits for the scan to complete, but for an invalid unit, scsi_scan_target directly calls the slave_destroy handler. Fix the deadlock by removing the wait in the slave_destroy handler, it was not necessary anyway.

* [SCSI] zfcp: Remove SCSI devices when removing complete adapterChristof Schmitt2008-01-111-0/+3
| | | | | | | | | | | The common I/O layer can call remove a handler to inform zfcp that a device disappeared. The handler zfcp_ccw_remove then removes all unit, port and the adapter data structures. Removing the units requires that the SCSI devices are removed first.

* [SCSI] aacraid: forced reset overrideSalyzyn, Mark2008-01-114-13/+19
| | | | | | | | | | | | | | | | | | | | | | Some of our vendors have requested that our adapters ignore the hardware reset attempts during recovery and have enforced this with changes in Adapter Firmware. Some of our customers have requested the option to be able to reset the adapter under adverse adapter failure, we even had a few defects reported here considering it a regression that the Adapter could not be reset. This patch addresses this dichotomy. The user can force the adapter to be reset if it supports the IOP_RESET_ALWAYS command, in cases where the adapter has been programmed to ignore the reset, by setting the aacraid.check_reset parameter to a value of -1. The driver will not reset an Adapter that does not support the reset command(s). This patch also fixes and cleans up some of the logic associated with resetting the adapter.

* [SCSI] add DID_REQUEUE string to scsi_show_result host tableMike Christie2008-01-111-1/+1
| | | | | | | | | | | | | I was working on patches which add new transport error values, when I noticed that DID_REQUEUE was not in the hostbyte_table. I do not think there is any way to hit the code path where scsi_show_result is called and where you return DID_REQUEUE, because DID_REQUEUE causes scsi-ml to always requeue the command. However, for completeness and because I want to one day send a patch that tries to add new host bytes values, I am sending this patch.

The aic994xx will accept "update bios_file" and "verify bios_file" commands to perform update and verify BIOS image . For example: Type "echo "update asc483c01.ufi" > /sys/devices/.../update_bios" to update BIOS image from /lib/firmware/as483c01.ufi file into HBA's flash memory. Type "echo "verify asc483c01.ufi" > /sys/devices/.../update_bios" to verify BIOS image between /lib/firmware/asc48c01.ufi file and HBA's flash memory. 4.

* | ps3fb: fix deadlock on kexec()Jeremy Kerr2008-01-111-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the introduction of the acquire_console_sem calls in 0333d83509c7d8496c8965b5ba9bc0c98e83c259, kexecing can cause the kernel to deadlock: ps3fb_shutdown() -> unregister_framebuffer() -> fb_notifier_call_chain(FB_EVENT_FB_UNBIND) -> fbcon_fb_unbind() -> unbind_con_driver() -> bind_con_driver() [ acquires console_sem ] -> fbcon_deinit() -> fbops->fb_release(newinfo, 0) -> ps3fb_release() -> ps3fb_sync() [ acquires console_sem ] This change avoids the deadlock by moving the acquire_console_sem() out of ps3fb_sync(), and puts it into the two other callsites, leaving ps3fb_release() to call ps3fb_sync() without the console semaphore. [Geert] - Corrected call sequence above - ps3fb_release() may be called with and without console_sem held. This is an inconsistency that should be fixed at the fb level, but for now, try to acquire console_sem in ps3fb_release(). I think it's safer to let ps3fb_release() try to acquire console_sem and not refresh the screen if it fails, than to call ps3fb_sync() without holding console_sem, as ps3fb_par may be modified at the same time, causing crashes or lockups. Besides, ps3fb_release() only calls ps3fb_sync() to refresh the screen when display flipping is disabled, which is an uncommon case (except during shutdown/kexec).

* | ps3fb: prevent use after free of fb_infoJeremy Kerr2008-01-111-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | In ps3fb_shutdown, freeing the framebuffer will cause fb_info (in dev->core.driver_data) to be free()ed, which we potentially access from the ps3fbd kthread. This change frees the framebuffer after stopping the ps3fbd kthread.
