* [SCSI] ipr: Fixup device type checkBrian King2006-04-13

* [SCSI] ipr: Disk remove path cleanupBrian King2006-04-13
| | | | | | | | | | | Instead of NULLing the resource entry pointer when a disk goes away to prevent any new commands being sent to it, set the adapter resource handle to an invalid value so new ops getting sent to it will fail with a selection timeout response. This patch is needed for future SATA patches. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

* [SCSI] for_each_possible_cpu: scsiKAMEZAWA Hiroyuki2006-04-13
| | | | | | | | | | | | | | | | for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future. This patch replaces for_each_cpu with for_each_possible_cpu.

* [SCSI] Enable clustering and large transfersMatthew Wilcox2006-04-13
| | | | | | | | | | | This patch enables clustering and sets max_sectors to 0xffff to enable reading and writing of large blocks with tapes (and large transfers with sg). This change is needed after the sg and st drivers started using chained bios through scsi_request_async() in 2.6.16.

* [SCSI] Simplify error handlingMatthew Wilcox2006-04-13
| | | | | | | | | | | | | | | | | | Use wait_for_completion_timeout() instead of using a timer (as Christoph Hellwig did for aic7xxx). That lets me eliminate the sym_eh_wait structure; the struct completion, the old_done pointer and the to_do flag can be folded into the sym_ucmd (which overrides the scsi_pointer in scsi_cmnd). The sym_eh_done() function becomes much simpler as the timeout handling is done in sym_eh_handler() directly. The host_lock can be unlocked earlier, and I cache the host in a local variable to make accesses to it quicker.

* [SCSI] unify SCSI_IOCTL_SEND_COMMAND implementationsChristoph Hellwig2006-04-13
| | | | | | | | | | | | | | | | | | | | | | We currently have two implementations of this obsolete ioctl, one in the block layer and one in the scsi code. Both of them have drawbacks. This patch kills the scsi layer version after updating the block version with the missing bits: - argument checking - use scatterlist I/O - set number of retries based on the submitted command This is the last user of non-S/G I/O except for the gdth driver, so getting this in ASAP and through the scsi tree would be nie to kill the non-S/G I/O path.

| * IB/mthca: Fix max_srq_sge returned by ib_query_device for Tavor devicesJack Morgenstein2006-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver allocates SRQ WQEs size with a power of 2 size both for Tavor and for memfree. For Tavor, however, the hardware only requires the WQE size to be a multiple of 16, not a power of 2, and the max number of scatter-gather allowed is reported accordingly by the firmware (and this is the value currently returned by ib_query_device() and ibv_query_device()). If the max number of scatter/gather entries reported by the FW is used when creating an SRQ, the creation will fail for Tavor, since the required WQE size will be increased to the next power of 2, which turns out to be larger than the device permitted max WQE size (which is not a power of 2). This patch reduces the reported SRQ max wqe size so that it can be used successfully in creating an SRQ on Tavor HCAs.

| | | | | | | | | | | | | | | | We know ipoib_flush_paths() is called from plain process context with interrupts enabled, since it does wait_for_completion(). So there's no need to use spin_lock_irqsave() -- spin_lock_irq() is fine. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| * IB/mthca: Disable tuning PCI read burst sizeMichael S. Tsirkin2006-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCI spec recommends against drivers playing with a device's PCI read burst size, and says that systems software should configure it. And we actually have users that report that changing it from the default set by BIOS hurts performance and/or stability for them. On the other hand, the Mellanox Programmer's Reference Manual recommends turning it up all the way to the maximum value. Some tests conducted here in the lab do not show performance improvement from this tuning, but this might be just me. As a work-around, make this tuning an option, off by default (safe value), with an eye towards removing it completely one day if no one complains. Signed-off-by: Michael S.

| | | | | | | | | | | | | | | | | | | | | | ipoib_mcast_restart_task() might free an mcast object while a join request is still outstanding, leading to an oops when the query completes. Fix this by waiting for query to complete, similar to what ipoib_stop_thread() is doing. The wait for mcast completion code is consolidated in wait_for_mcast_join().

| * IB: simplify static rate encodingJack Morgenstein2006-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Push translation of static rate to HCA format into low-level drivers, where it belongs. For static rate encoding, use encoding of rate field from IB standard PathRecord, with addition of value 0, for backwards compatibility with current usage. The changes are: - Add enum ib_rate to midlayer includes. - Get rid of static rate translation in IPoIB; just use static rate directly from Path and MulticastGroup records. - Update mthca driver to translate absolute static rate into the format used by hardware. This also fixes mthca's static rate handling for HCAs that are capable of 4X DDR. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
