* [SCSI] st: add struct rq_map_data supportFUJITA Tomonori2009-01-022-0/+13
| | | | | | | | | | | This adds struct rq_map_data and the array of pointers to store fragment buffers to struct st_buffer. This patch doesn't remove st_buf_fragment but the latter patch does.

* [SCSI] st: make all the fragment buffers the same sizeFUJITA Tomonori2009-01-021-9/+9
| | | | | | | | | | | | This patch simiplifies the fragment buffer management a bit, all the buffers in the fragment list become the same size. This is necessary to use the block layer API (sg driver was modified in the same way) since the block layer API takes the same size page frames instead of scatter gatter.

* [SCSI] block: make blk_rq_map_user take a NULL user-space buffer for WRITEFUJITA Tomonori2009-01-021-0/+1
| | | | | | | | | | | | | | | | The commit 818827669d85b84241696ffef2de485db46b0b5e (block: make blk_rq_map_user take a NULL user-space buffer) extended blk_rq_map_user to accept a NULL user-space buffer with a READ command. It was necessary to convert sg to use the block layer mapping API. This patch extends blk_rq_map_user again for a WRITE command. It is necessary to convert st and osst drivers to use the block layer apping API.

* [SCSI] block: fix the partial mappings with struct rq_map_dataFUJITA Tomonori2009-01-021-0/+1
| | | | | | | | | | | | This fixes bio_copy_user_iov to properly handle the partial mappings with struct rq_map_data (which only sg uses for now but st and osst will shortly). It adds the offset member to struct rq_map_data and changes blk_rq_map_user to update it so that bio_copy_user_iov can add an appropriate page frame via bio_add_pc_page().

* [SCSI] ibmvscsi: Make max_requests module parameter more accurateBrian King2009-01-021-6/+10
| | | | | | | | | | | | In a previous patch to fix an issue with error recovery, the behavior of the max_requests module paramater was also changed. If, for some reason, max_requests is set to one by the user, we will end up with a negative number for can_queue. Fix this by making max_requests not include the two event structs needed to do error recovery.

* [SCSI] sgiwd93: Fix compilation warningDmitri Vorobiev2009-01-021-1/+2
| | | | | | | | | | | | | | | | | The remove() callback in platform drivers should return int in accordance to the definition of the platform_driver structure. However, the SGI-specific WD93 SCSI controller driver defines the callback as a void function, which causes the following compilation warning: drivers/scsi/sgiwd93.c:314: warning: initialization from incompatible pointer type This patch fixes the warning by changing the return type of the remove() callback to what the core driver code requires.

* [SCSI] ibmvfc: Fixup command response translationBrian King2009-01-021-5/+5
| | | | | | | | | | | | If a link down event is received, outstanding commands may get returned to the ibmvfc driver with a "transaction cancelled implicit" response. This is currently translated to DID_ABORT, which does not get retried by SCSI core, but rather passes the failure up the stack. This can result in I/O errors at the filesystem level. Fix up this response a well as a few other error responses. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

The upper 4 layers are fc_lport, fc_disc, fc_rport and fc_fcp. A LLD that uses libfc could choose to either use libfc's block, or using the transport template defined in libfc.h, override one or more blocks with its own implementation. The EM (Exchange Manager) manages exhcanges/sequences for all commands- ELS, CT and FCP. The framing library frames ELS and CT commands. The fc_lport block manages the library's representation of the host's FC enabled ports. The fc_disc block manages discovery of targets as well as handling changes that occur in the FC fabric (via. RSCN events). The fc_rport block manages the library's representation of other entities in the FC fabric. Currently the library uses this block for targets, its peer when in point-to-point mode and the directory server, but can be extended for other entities if needed. The fc_fcp block interacts with the scsi-ml and handles all I/O.

| * [SCSI] ibmvscsi: Don't fail EH due to insufficient resourcesBrian King2008-12-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ibmvscsi driver currently has a bug in it which can result in it using up all its event structs for commands. If something results in all those commands timing out, we won't have any resources left to send aborts or resets. This results in escalating to a host reset in order to recover, which is a bit heavy handed. This fixes it by reducing can_queue by two in order to have resources to do EH. It also changes the max_requests module parameter so that it is not writable at runtime, since the code really does not handle it changing at runtime.

| * [SCSI] st: add st_scsi_kern_execute helper functionFUJITA Tomonori2008-12-291-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | st_scsi_kern_execute is a helper function to perform SCSI commands synchronously. It supports data transfer with a liner in-kernel buffer (not scatter gather). st_scsi_kern_execute internally uses scsi_execute(). The majority of st_do_scsi can be replaced with st_scsi_kern_execute. This is a preparation for rewriting st_do_scsi to remove obsolete scsi_execute_async().

| * [SCSI] lpfc 8.3.0 : Add active interrupt test for enabling MSI/MSI-X/INTxJames Smart2008-12-294-154/+302
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per the recent discussions at the Linux Plumbers Conference, when enabling MSI or MSI-X, generate a test interrupt to verify the interrupt routing is working properly. If the test interrupt fails, fall back to MSI first, and if that fails as well, to INTx. If the interrupt test fails with INTx, log an error and fail the PCI probe. Also changed the use of spin_(lock|unlock) to the _irq(save|restore) variants in the interrupt handlers because with multi-message MSI-X, both interrupt handlers can now run in parallel.
