This updates bsg entry in Kconfig: - bsg supports sg v4 - bsg depends on SCSI - it might be better to mark it experimental for a while Signed-off-by:

This enables bsg to handle SCSI transport-level request like SAS management protocol (SMP). - add BSG_SUB_PROTOCOL_{SCSI_CMD, SCSI_TMF, SCSI_TRANSPORT} definitions. - SCSI transport-level requests skip blk_verify_command(). Signed-off-by: -

bsg uses the rq->next_rq pointer for a bidi request. Signed-off-by:
-
FUJITA Tomonori authored
This adds a struct request pointer to the request structure for the second data phase (bidi for now). A request queue supporting bidi requests sets QUEUE_FLAG_BIDI. This prevents sending bidi requests to a non-bidi queue. Signed-off-by:

This patch fixes a bug that read() returns ENODATA even with a blocking file descriptor when there are no commands pending. This also includes some cleanups. Signed-off-by:

This patch addresses on two issues on bsg device allocation. - the current maxium number of bsg devices is 256. It's too small if we allocate bsg devices to all SCSI devices, transport entities, etc. This increses the maxium number to 32768 (taken from the sg driver). - SCSI devices are dynamically added and removed. Currently, bsg can't handle it well since bsd_device->minor is simply increased. This is dependent on the patchset that I posted yesterday: http://marc.info/?l=linux-scsi&m=117440208726755&w=2Signed-off-by:

This patch binds bsg to all SCSI devices (their request queues) like the current sg driver does. We can send SCSI commands to non disk and cdrom scsi devices like OSD via bsg. This patch removes bsg_register_queue from blk_register_queue so bsg devices aren't bound to non SCSI block devices. If they want bsg, I'll send a patch to do that. Signed-off-by:

This patch binds bsg devices to request_queue instead of gendisk. Any objects (like transport entities) can define own request_handler and create own bsg device. Signed-off-by:
-
FUJITA Tomonori authored
bsg uses scsi_cmd_ioctl() for some SCSI/sg ioctl commands. scsi_cmd_ioctl() gets a request queue from a gendisk arguement. This prevents bsg being bound to SCSI devices that don't have a gendisk (like OSD). This adds a request_queue argument to scsi_cmd_ioctl(). The SCSI/sg ioctl commands doesn't use a gendisk so it's safe for any SCSI devices to use scsi_cmd_ioctl(). Signed-off-by:

FUJITA Tomonori authored
This patch replaces SG v3 in bsg with SG v4 (except for SG_IO). Signed-off-by:
-
FUJITA Tomonori authored
This patch adds sg_io_v4 structure that Doug proposed last month. There's one major change from the RFC. I dropped iovec, which needs compat stuff. The bsg code simply calls blk_rq_map_user against dout_xferp/din_xferp. So if possible, the page frames are directly mapped. If not possible, the block layer allocates new page frames and does memory copies. Signed-off-by:

It depends on tristate I2C and it's trivial to make modular. The current Kconfig allows I2C=m, I2C_ACORN=y, which doesn't work at all; alternatives are dependency on I2C=y and making I2C_ACORN itself a tristate. The latter is the right thing to do... Signed-off-by:
