* [SCSI] aic7xxx: remove scsi_assign_lock usageChristoph Hellwig2005-11-061-23/+16
| | | | | | | | 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>
* [SCSI] use scmd_id(), scmd_channel() throughout codeJeff Garzik2005-10-281-5/+5
| | | | | | | | | | | 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>

* [SCSI] aic7xxx/aic79xx: fix module removal path not to panicJames Bottomley2005-10-021-5/+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.

* [SCSI] aic7xxx: move to dma_get_required_mask() and correct 39 bit assumptionsJames Bottomley2005-09-131-9/+0
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | 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>

* | [SCSI] fix aic7xxx performance issues since 2.6.12-rc2James Bottomley2005-08-041-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several people noticed we dropped quite a bit on benchmark figures. OK, it was my fault but unfortunately I discovered I ran out of brown paper bags a while ago and forgot to reorder them. The issue is that a construct introduced in the conversion of the driver to use the transport class keyed off whether the block request was tagged or not. However, the aic7xxx driver doesn't properly set up the block layer TCQ (it uses the wrong API), so the driver now things all requests are untagged and we keep it to a queue depth of a single element. Oops. The fix is to use the correct TCQ API. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* | [SCSI] aic7xxx: final fixes for DT handlingJames Bottomley2005-08-021-4/+4
| | | | | | | | | | | | | | | | The aic7xxx can support Data Group transfers at periods > 12.5, so eliminate that restriction. Additionally wide is a requirement for DT so ensure wide is set if users request DT. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* | [SCSI] aic7xxx: fix bug in DT handingJames Bottomley2005-07-301-4/+6
|/ | | | | | | | | | | Basically DT isn't reported or handled at all. The problem is that lines of code like this: spi_dt(starget) = tinfo->curr.ppr_options & MSG_EXT_PPR_DT_REQ; don't do what you think they do when spi_dt is a single bit variable.

* [SCSI] aic7xxx: fix boot hang with Fujitsu drivesJames Bottomley2005-07-031-0/+8
| | | | | | | | | | Apparently these are the only drives that try to negotiate IU and QAS at u160 speeds. The aic7xxx driver can't cope with this. The fix is to eliminate the IU and QAS setting routines. I've #if 0'd them out, just in case we ever get the sequencer documentation out of Adaptec, since we'd then be able to fix the driver.

* [SCSI] fix aic7xxx coupled parameter problemJames Bottomley2005-06-031-13/+13

* [SCSI] aic7xxx: remove separate target and device allocationsJames Bottomley2005-05-261-374/+201
| | | | | | | | | | Since the aic driver is now taught to speak in terms of the generic linux devices, we can now also dispense with the transport class get routines (since we update the parameters when the driver sees they change) and also plumb it into the spi transport transfer agreement reporting infrastructure.

* [SCSI] aic7xxx: fix U160 modeJames Bottomley2005-05-201-0/+11
| | | | | | | | | | The new period/dt setting routines don't get the coupling of these parameters correct. This means that Domain Validation never gets DT set, and thus the drive gets restricted to U80. Fix this by restoring the couplings in the set routines.

* [SCSI] aic7xxx: add back lockingJames Bottomley2005-05-201-4/+11
| | | | | | | | Tampering with the settings has to be done under the host lock ... slave_alloc isn't called under any lock, so this has to be done explicitly. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] aic7xxx: make correct use of slave_alloc/destroy and remove the per ↵James Bottomley2005-05-201-104/+79
| | | | | | | | | | | | | | | | | | | | | | | device timer The allocation of all of our components should be done in slave alloc. Currently it's rather fancifully refcounted in the queuecommand callback. This patch moves allocation and destroy to their correct places in slave_alloc/slave_destory. Now we can guarantee that everywhere a device is requested, it's actually been allocated, so don't check for this anymore. Additionally, the per device busy timer was the only source of potential use after free. It's been deleted because Linux does the correct thing with busy returns, so there's no need to implement a separate timer in the driver. Finally, implement code that forces all the device parameters to zero (i.e. async and narrow) in the slave alloc, inform the spi class of the bios recorded maximums and wait until slave configure before trying anything more adventurous.

* [SCSI] aic7xxx: remove the completeqJames Bottomley2005-05-201-119/+2

* [SCSI] remove aic7xxx busyqJames Bottomley2005-05-201-435/+190
| | | | | | | | | | | | | The aic7xxx driver has two spurious queues in it's linux glue code: the busyq which queues incoming commands to the driver and the completeq which queues finished commands before sending them back to the mid-layer This patch just removes the busyq and makes the aic finally return the correct status to get the mid-layer to manage its queueing, so a command is either committed to the sequencer or returned to the midlayer for requeue.

* aic7xxx: convert to SPI transport class Domain Validation2005-04-181-1671/+10
| | | | | | | | | | | Now that we export all the parameters, this is easy to do. It also means that we can dump about 2000 lines of code that were dedicated to doing this internally. Additionally, this removes all the aic7xxx driver abuse of SCSI timers which were embedded in the DV routines. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* aic7xxx: add support for the SPI transport class2005-04-181-0/+261

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!
