* iommu sg merging: call dma_set_seg_boundary in __scsi_alloc_queue()FUJITA Tomonori2008-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a one-line patch to add the following to __scsi_alloc_queue(): dma_set_seg_boundary(dev, shost->dma_boundary); This is the simplest approach but the result looks odd, __scsi_alloc_queue() does: blk_queue_segment_boundary(q, shost->dma_boundary); dma_set_seg_boundary(dev, shost->dma_boundary); blk_queue_max_segment_size(q, dma_get_max_seg_size(dev)); I think that it would be better to set up segment boundary in the same way as we did for the maximum segment size. That is, removing shost->dma_boundary and LLDs call pci_set_dma_seg_boundary (or its friends). Then __scsi_alloc_queue() can set up both limits in the same way: blk_queue_segment_boundary(q, dma_get_seg_boundary(dev)); blk_queue_max_segment_size(q, dma_get_max_seg_size(dev)); killing dma_boundary in scsi_host_template needs a large patch for libata (dma_boundary is used by only libata and sym53c8xx). I'll send a patch to do that if it is acceptable. James and Jeff?

* iommu sg merging: call blk_queue_segment_boundary in __scsi_alloc_queueFUJITA Tomonori2008-02-05
| | | | | | | | | | | | | | | | request_queue and device struct must have the same value of a segment size limit. This patch adds blk_queue_segment_boundary in __scsi_alloc_queue so LLDs don't need to call both blk_queue_segment_boundary and set_dma_max_seg_size. A LLD can change the default value (64KB) can call device_dma_parameters accessors like pci_set_dma_max_seg_size when allocating scsi_host.

* pcmcia: convert some internal-only ioaddr_t to unsigned intOlof Johansson2008-02-05
| | | | | | | | | | | | | | | | | | | | | | | | Convert the io_req_t members to unsigned int, to allow use on machines with more than 16 bits worth of IO ports (i.e. secondary busses on ppc64, etc). There was only a couple of places in drivers where a change was needed. I left printk formats alone (there are lots of %04x-style formats in there), mostly to not change the format on the platforms that only have 16-bit io addresses, but also because the padding doesn't really add all that much value most of the time. I found only one sprintf of an address, and upsized the string accordingly (I doubt anyone will have anywhere near INT_MAX as irq value, but at least there's room for it now).

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building the aic7xxx driver includes the copy of an .h file from a _shipped file. In a highly parallel build Ingo saw that the build sometimes failed (included distcc usage). It was tracked down to a missing dependency from the .c source file to the generated .h file. We started to build the .c file before the copy (cat) operation of the .h file completed and we then only got half of the definitions from the copied .h file. Add an explicit dependency from the .c files to the generated .h files so make knows all dependencies and finsih the build of the .h files before it starts building the .o files. Ingo tested this fix and reported: good news: hundreds of successful kernel builds and no failures overnight.

* [SCSI] bidirectional command supportBoaz Harrosh2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* [ETH]: Combine format_addr() with print_mac().Michael Chan2008-01-28
| | | | | | | | | | | | | | | | | | | print_mac() used many most net drivers and format_addr() used by net-sysfs.c are very similar and they can be intergrated. format_addr() is also identically redefined in the qla4xxx iscsi driver. Export a new function sysfs_format_mac() to be used by net-sysfs, qla4xxx and others in the future. Both print_mac() and sysfs_format_mac() call _format_mac_addr() to do the formatting. Changed print_mac() to use unsigned char * to be consistent with net_device struct's dev_addr. Added buffer length overrun checking as suggested by Joe Perches.

| * blktrace: Add blktrace ioctls to SCSI generic devicesChristof Schmitt2008-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the SCSI layer uses the request queues from the block layer, blktrace can also be used to trace the requests to all SCSI devices (like SCSI tape drives), not only disks. The only missing part is the ioctl interface to start and stop tracing. This patch adds the SETUP, START, STOP and TEARDOWN ioctls from blktrace to the sg device files. With this change, blktrace can be used for SCSI devices like for disks, e.g.: blktrace -d /dev/sg1 -o - | blkparse -i - Signed-off-by: Christof Schmitt <christof.schmitt@de.ibm.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

* | SG: work with the SCSI fixed maximum allocations.James Bottomley2008-01-28
| | | | | | | | | | | | | | | | | | | | | | | | SCSI sg table allocation has a maximum size (of SCSI_MAX_SG_SEGMENTS, currently 128) and this will cause a BUG_ON() in SCSI if something tries an allocation over it. This patch adds a size limit to the chaining allocator to allow the specification of the maximum allocation size for chaining, so we always chain in units of the maximum SCSI allocation size.
