2006-06-10[SCSI] aic7xxx: expose the bus setting to sysfsJames Bottomley3-7/+92
Read the transciever register and display in the host transport properties. I'm still not entirely sure what this does for multiple transciever adapters (like some 160 ones) however, I suspect it displays the transciever state of the switchable bus segment.

max_id now means the maximum number of ids on the bus, which means it is one greater than the largest possible id number. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-04-13[SCSI] aic79xx: target hotplug fixesHannes Reinecke2-44/+10
When a target is added aic79xx tries to be overly clever: it changes the command on the fly to TEST UNIT READY and tries to requeue the original command. Sadly this breaks SCSI compability and of course the midlayer is getting a bit confused by it. So we're just removing that bit of code and let the midlayer deal with it. It's clever enough by now. And the driver code is getting simpler. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-04-13[SCSI] aic79xx bus reset updateHannes Reinecke3-62/+58
As James B. correctly noted, ahd_reset_channel() in ahd_linux_bus_reset() should be protected by ahd_lock(). However, the main reason for not doing so was a deadlock with the interesting polling mechanism to detect the end a bus reset. This patch replaces the polling mechanism with a saner signalling via flags; it also gives us the benefit of detecting any multiple calls to ahd_reset_channel().

2006-03-12[SCSI] aic79xx: Avoid renegotiation on inquiryHannes Reinecke1-24/+0
Because of some quirk in the SCSI spec the aic79xx driver chose to force a renegotiation when sending an inquiry. This should better be handled by the upper layers if required at all. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

This patch fixes the aic79xx driver to properly respond to BIOS settings. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-03-12[SCSI] aic79xx: Invalid Sequencer interrupt occuredHannes Reinecke1-2/+6
On certain systems the driver seems to hit upon some "scsi0: Invalid Sequencer interrupt occurred." problem and dumps card state. According to Adaptec engineers this message is harmless. So as not to confuse user we can as well disable the internal card state dump and just print out the message itself.

2006-03-12[SCSI] aic79xx: Update error recoveryHannes Reinecke1-124/+201
This patch updates the error recovery. Routines for TARGET RESET and ABORT COMMAND are split up as the logic is quite dissimilar. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-03-12[SCSI] aic79xx: use tcq functionsHannes Reinecke1-9/+5
This patch converts aic79xx to use the midlayer-supplied tcq functions. We also set the queuedepth to '1' if tcq is disabled; the aic79xx driver gets confused otherwise. Will set it back to '2' once I figure out how to queue requests in the driver. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-03-12[SCSI] aic79xx: remove qfrozenHannes Reinecke2-82/+27
This patch removes the need for platform_data->qfrozen. We're now using complete() instead of semaphores thus simplifying ahd_freeze_simq() quite a lot. This also fixes some deadlocks in the recovery code (again). Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

New version that switches to the common onstack completion and just a pointer in the platform_data struct idiom. This gets rid of all the flags fiddling.

2006-01-12[SCSI] aic7xxx: fix timer handling bugJames Bottomley3-41/+16
The driver is doing a rather stupid mod_timer allegedly to "give request sense more time to complete". This is illegal and pointless, so just eliminate it. Also eliminate all the other uses of struct timer_list in the driver, which are mostly bogus. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2005-11-28[SCSI] aic7xxx: reset handler selects a wrong commandVasily Averin2-2/+2
To transport scsi reset command to device aic7xxx reset handler looks at the driver's pending_list and searches any proper command. However the search condition has been inverted: ahc_match_scb() returns TRUE if a matched command is found. As a result the reset on required devices did not turn out well, a correctly working neighbour device may be surprised by the reset. aic7xxx reset handler reports about the success, but really the original situation is not corrected yet. Signed-off-by: Vasily Averin <vvs@sw.ru> Naturally, there's a corresponding problem in the aic79xx driver, so I've also added the same fix for that.

2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering2-2/+0
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Wrap a highly common idiom. Makes the code easier to read, helps pave the way for sdev->{id,channel} removal, and adds a token that can easily by grepped-for in the future.

2005-10-03[SCSI] aic7xxx/aic79xx: fix module removal path not to panicJames Bottomley5-10/+15
In these drivers, scsi_remove_host() is called too late, at the point it is called, the driver has already shut down too far to accept any I/O that the shutdown might generate. Any generated I/O actually triggers a panic. Fix this by calling scsi_remove_host() as early as possible and not calling scsi_host_put() until just before we kfree the ahc_softc.

2005-09-13[SCSI] aic7xxx: move to dma_get_required_mask() and correct 39 bit assumptionsJames Bottomley3-14/+5
This patch moves aic7xxx over to the dma_get_required_mask() API and dumps its open coded memory check. It also appears from this bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=167049 That 39 bit addressing doesn't work on older cards. I surmise that the AHC_LARGE_SCBS flag is the one that marks cards capable of using 39 bit addressing, so I also folded that check into the code.
