2006-06-10[SCSI] drivers/scsi: Use ARRAY_SIZE macroTobias Klauser1-10/+10
Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]) and remove duplicates of the macro. Signed-off-by: Tobias Klauser <tklauser@nuerscht.ch> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-04-13[SCSI] aic79xx bus reset updateHannes Reinecke1-0/+4
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>
2006-03-12[SCSI] aic79xx: use BIOS settingsHannes Reinecke1-7/+28
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: 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: Remove dead codeHannes Reinecke1-59/+0

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 Reinecke1-78/+26
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>
2006-01-31[SCSI] aic79xx: Fix timer handlingHannes Reinecke1-11/+15
Fix the timer handling in aic79xx to use the SCSI-ML provided handling instead of implementing our own. It also fixes a deadlock in the command recovery code. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-01-31[SCSI] aic79xx: SLOWCRC fixHannes Reinecke1-0/+17
This patch introduces the SLOWCRC handling for certain buggy chipsets. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-01-12[SCSI] aic79xx: Sequencer updateHannes Reinecke1-11/+51
Update sequencer code to Adaptec version 2.0.12-6.3.9. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-15[SCSI] handle scsi_add_host failure for aic79xx and fix compiler warningJesper Juhl1-2/+9
Add scsi_add_host() failure handling for aic79xx Also silence a compiler warning : drivers/scsi/aic7xxx/aic79xx_osm.c: In function `ahd_linux_register_host': drivers/scsi/aic7xxx/aic79xx_osm.c:1099: warning: ignoring return value of `scsi_add_host', declared with attribute warn_unused_result Signed-off-by: Jesper Juhl <jesper.juhl@gmail.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-11-28[SCSI] aic7xxx: reset handler selects a wrong commandVasily Averin1-1/+1
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. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-11-06[SCSI] aic79xx: remove scsi_assign_lock usageChristoph Hellwig1-23/+14
just take the internal lock in queuecommand instead. also switch the only direct use of the internal lock to the wrappers used elsewhere. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-10-29[SCSI] use scmd_id(), scmd_channel() throughout codeJeff Garzik1-5/+6
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. There are a couple sdev_id() and scmd_printk() updates thrown in as well. Rejections fixed up and Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-10-29[SCSI] use sfoo_printk() in driversJeff Garzik1-19/+9

2005-10-03[SCSI] aic7xxx/aic79xx: fix module removal path not to panicJames Bottomley1-5/+3
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. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-09-05[SCSI] aic7xxx: remove aiclib.cChristoph Hellwig1-12/+84
#include of C files and macro tricks to rename symbols are evil and just cause trouble. Let's doublicate the two functions as they're going to go away soon enough anyway. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-15[SCSI] aic79xx: sane pci probingChristoph Hellwig1-88/+20
remove ahd_tailq and do sane pci probing. ported over from aic7xxx. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-09[SCSI] aic79xx: fix boot panic with no hardwareJames Bottomley1-3/+1
There's a spurious (and illegal since it's marked __exit) call to ahc_linux_exit() in ahc_linux_init() which causes a double list deletion of the transport class; remove it. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-06[SCSI] aic7xxx/79xx: fix another potential panic due to a non existent targetJames Bottomley1-2/+2
I ran into this one sending bus resets across the hardware. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-05[SCSI] aic79xx: fixup DT settingHannes Reinecke1-2/+3
this patch is just a cross-port of the fixup for aic7xxx DT settings. As the same restrictions apply for aic79xx also (DT requires wide transfers) the dt setting routine should be modified equivalently. And an invalid period setting will be caught by ahd_find_syncrate() anyway. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-04[SCSI] aic79xx: add hold_mcs to the transport parametersJames Bottomley1-1/+37
since this card can support the setting, add it to the parameter list. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-03[SCSI] aic79xx: fix up transport settingsJames Bottomley1-30/+9
There's a slight problem in the way you've done the transport parameters; reading from the variables actually produces the current settings, not the ones you just set (and there's usually a lag because devices don't renegotiate until the next command goes over the bus). If you set the bit immediately, you get into the situation where the transport parameters report something as being set even if the drive cannot support it. I patched the driver to do it this way and also corrected a panic in the proc routines. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-03[SCSI] aic79xx: DV parameter settingsHannes Reinecke1-13/+218
This patch updates various scsi_transport_spi parameters with the actual parameters used by the driver internally. Domain Validation for all devices should now work properly. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-03[SCSI] aic79xx: update to use scsi_transport_spiHannes Reinecke1-2662/+759
This patch updates the aic79xx driver to take advantage of the scsi_transport_spi infrastructure. Patch is quite a mess as some procedures have been reshuffled to be closer to the aic7xxx driver. Rejections fixed and Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-08-03[SCSI] aic79xx: Remove busyqHannes Reinecke1-686/+138
From: Jeff Garzik <jgarzik@pobox.com> This patch removes the busyq in aic79xx and uses the command-queue from the midlayer instead. Additionally some dead code is removed. Signed-off-by: Hannes Reinecke <hare@suse.de> Fixed rejections Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2005-04-18[PATCH] remove old scsi data direction macros1-9/+9
these have been wrappers for the generic dma direction bits since 2.5.x. This patch converts the few remaining drivers and removes the macros. Arjan noticed there's some hunk in here that shouldn't. Updated patch below: Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+5017
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
