* [SCSI] remove use_sg_chainingJames Bottomley2008-01-3039-96/+18
| | | | | | | | | | | With the sg table code, every SCSI driver is now either chain capable or broken (or has sg_tablesize set so chaining is never activated), so there's no need to have a check in the host template. Also tidy up the code by moving the scatterlist size defines into the SCSI includes and permit the last entry of the scatterlist pools not to be a power of two.

* [SCSI] bidirectional command supportBoaz Harrosh2008-01-302-15/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the block level bidi request uses req->next_rq pointer for a second bidi_read request. At Scsi-midlayer a second scsi_data_buffer structure is used for the bidi_read part. This bidi scsi_data_buffer is put on request->next_rq->special. Struct scsi_cmnd is not changed. - Define scsi_bidi_cmnd() to return true if it is a bidi request and a second sgtable was allocated. - Define scsi_in()/scsi_out() to return the in or out scsi_data_buffer from this command This API is to isolate users from the mechanics of bidi. - Define scsi_end_bidi_request() to do what scsi_end_request() does but for a bidi request. This is necessary because bidi commands are a bit tricky here. (See comments in body) - scsi_release_buffers() will also release the bidi_read scsi_data_buffer - scsi_io_completion() on bidi commands will now call scsi_end_bidi_request() and return. - The previous work done in scsi_init_io() is now done in a new scsi_init_sgtable() (which is 99% identical to old scsi_init_io()) The new scsi_init_io() will call the above twice if needed also for the bidi_read command. Only at this point is a command bidi. - In scsi_error.c at scsi_eh_prep/restore_cmnd() make sure bidi-lld is not confused by a get-sense command that looks like bidi. This is done by puting NULL at request->next_rq, and restoring.

* [SCSI] implement scsi_data_bufferBoaz Harrosh2008-01-306-74/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for bidi we abstract all IO members of scsi_cmnd, that will need to duplicate, into a substructure. - Group all IO members of scsi_cmnd into a scsi_data_buffer structure. - Adjust accessors to new members. - scsi_{alloc,free}_sgtable receive a scsi_data_buffer instead of scsi_cmnd. And work on it. - Adjust scsi_init_io() and scsi_release_buffers() for above change. - Fix other parts of scsi_lib/scsi.c to members migration. Use accessors where appropriate. - fix Documentation about scsi_cmnd in scsi_host.h - scsi_error.c * Changed needed members of struct scsi_eh_save. * Careful considerations in scsi_eh_prep/restore_cmnd. - sd.c and sr.c * sd and sr would adjust IO size to align on device's block size so code needs to change once we move to scsi_data_buff implementation. * Convert code to use scsi_for_each_sg * Use data accessors where appropriate. - tgt: convert libsrp to use scsi_data_buffer - isd200: This driver still bangs on scsi_cmnd IO members, so need changing [jejb: rebased on top of sg_table patches fixed up conflicts and used the synergy to eliminate use_sg and sg_count] Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* [SCSI] tgt: use scsi_init_io instead of scsi_alloc_sgtableBoaz Harrosh2008-01-302-34/+14
| | | | | | | | | | | | | | If we export scsi_init_io()/scsi_release_buffers() instead of scsi_{alloc,free}_sgtable() from scsi_lib than tgt code is much more insulated from scsi_lib changes. As a bonus it will also gain bidi capability when it comes.

| * [SCSI] use dynamically allocated sense bufferFUJITA Tomonori2008-01-233-3/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes static array sense_buffer in scsi_cmnd and uses dynamically allocated sense_buffer (with GFP_DMA). The reason for doing this is that some architectures need cacheline aligned buffer for DMA: http://lkml.org/lkml/2007/11/19/2 The problems are that scsi_eh_prep_cmnd puts scsi_cmnd::sense_buffer to sglist and some LLDs directly DMA to scsi_cmnd::sense_buffer. It's necessary to DMA to scsi_cmnd::sense_buffer safely. This patch solves these issues. __scsi_get_command allocates sense_buffer via kmem_cache_alloc and attaches it to a scsi_cmnd so everything just work as before.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cards being added are supported in a limited sense already through family matching, but we needed to add some functionality to the driver to expose selectively the physical drives. These Physical drives are specifically marked to not be part of any array and thus are declared JBODs (Just a Bunch Of Drives) for generic SCSI access. We report that this is the second patch in a set of two, but merely depends on the stand-alone functionality of the first patch which adds in that case the ability to report a driver feature flag via sysfs. We leverage that functionality by reporting that this driver now supports this new JBOD feature for the controller so that the array management applications may react accordingly and guide the user as they manage the controller.

Breaking from the one-line output typical of sysfs entries, newline was added to tailor for grep, or simple gets line by line string match within an application. I added one for a compiler time check for existence of debug print output, one for an optional manifest defined enhanced status reporting in the logs, and one for runtime reporting whether the controller and driver supports arrays larger than 2TB. Adaptec's storage management software uses the last flag to determine whether to make available the creation of arrays larger than 2TB, otherwise a warning is posted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FCE support enables the firmware to record FC extended link services and basic link services frames which have been transmitted and received by the ISP. This allows for a limited view of the FC traffic through the ISP without using a FC analyzer. This can be useful in situations where a physical connection to the FC bus is not possible. The driver exports this information in two ways -- first, via a debugfs node exported for all supported ISPs under: <debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce where a read of the 'fce' file will provide a snapshot of the firmware's FCE buffer; and finally, the FCE buffer will be extracted during a firmware-dump scenario.
