| * ieee1394: sbp2: enable auto spin-up for all SBP-2 devicesStefan Richter2006-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a follow-up to patch "ieee1394: sbp2: enable auto spin-up for Maxtor disks". When I 'ejected' an OXUF922 based HDD from a Mac OS X box, it was spun down by the Mac and did not spin up by itself when attached to a Linux box right after that. The first SCSI command that required the bridge to access the drive ended in sda:<6>sd 18:0:0:0: Device not ready: <6>: Current: sense key: Not Ready Additional sense: Logical unit not ready, initializing cmd. required Therefore the flag which instructs scsi_mod to send START STOP UNIT with START=1 ("make medium ready") after such a condition is now enabled unconditionally for all FireWire storage devices.

| * ieee1394: sbp2: don't prefer MODE SENSE 10Stefan Richter2006-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the old days, sbp2 used to coerce all MODE SENSE commands into the 10 bytes version. When all command set conversions were removed from sbp2 several months ago, sdev->use_10_for_ms = 1 was added. Meaning, higher SCSI layers preferred the 10 bytes version but would try the 6 bytes version if the former failed. Recently, a problem with the 10 bytes version was discovered. An Initio INIC-1530 firmware accepted the 10 bytes version but replied with bogus data, showing the HDD incorrectly as write-protected. Since RBC actually mandates MODE SENSE (6), I checked which version was sent by Windows XP and Mac OS X 10.3 to an SBP-2 target hosted by Linux --- it was the 6 bytes version. (Exception: OS X sent the 10 bytes version to an MMC target. RBC and SBC got MODE SENSE (6).) Therefore, drop the use_10_for_ms flag from sbp2. Now the upper layers will try MODE SENSE (6) before MODE SENSE (10) on all SBP-2 devices. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

| * ieee1394: sbp2: prevent rare deadlock in shutdownStefan Richter2006-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Scsi_remove_device() may go into uninterruptible sleep if blocked. Therefore sbp2_remove() unblocks the Scsi_Host before the device is requested to be removed. But there could be another 1394 bus reset after that which would block the host again. The 1394 subsystem won't call sbp2_update() concurrently to sbp2_remove(), which is why there is no chance for sbp2_remove() to be unblocked by sbp2_update(). The fix is to tell sbp2's bus reset handler when a device is to be shut down so that it skips scsi_block_requests() on that host. As before, any new commands after a reset without reconnect will be failed quickly by sbp2scsi_queuecommand(). In the long term, means to go without scsi_block_requests() should be found.

| * ieee1394: sbp2: handle "sbp2util_node_write_no_wait failed"Stefan Richter2006-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix for http://bugzilla.kernel.org/show_bug.cgi?id=6948 Because sbp2 writes to the target's fetch agent's registers from within atomic context, it cannot sleep to guaranteedly get a free transaction label. This may repeatedly lead to "sbp2util_node_write_no_wait failed" and consequently to SCSI command abortion after timeout. A likely cause is that many queue_command softirqs may occur before khpsbpkt (the ieee1394 driver's thread which cleans up after finished transactions) is woken up to recycle tlabels. Sbp2 now schedules a workqueue job whenever sbp2_link_orb_command fails in sbp2util_node_write_no_wait. The job will reliably get a transaction label because it can sleep. We use the kernel-wide shared workqueue because it is unlikely that the job itself actually needs to sleep. In the improbable case that it has to sleep, it doesn't need to sleep long since the standard transaction timeout is 100ms. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

| * ieee1394: sbp2: more checks of status blockStefan Richter2006-09-17

TODO: Check if 'src'==1, then withhold the respective ORB from reuse until status for any subsequent ORB was received. This is an old bug whose fix requires more complex command queue handling.

| * ieee1394: sbp2: safer initialization of status fifoStefan Richter2006-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sbp2's copy of the status fifo was cleared when management ORBs or new command ORBs were prepared. The latter had potential for a race condition if the block layer's soft IRQ and the 1394 LLD's interrupt handler ran on different CPUs. It would also yield wrong status if a command was completed with non-zero completion status before other commands that had zero completion status, and no new command was enqueued in the meantime. Now, the status buffer is cleared right before it is written. Thus it ends up in the following simpler and safer access pattern: - sbp2_alloc_device: allocates and implicitly clears once, - sbp2_handle_status_write: clears, writes, and reads, - sbp2_query_logins, sbp2_login_device, sbp2_reconnect_device: read. The latter three do not race with sbp2_handle_status_write because of how the protocol works. As a tiny optimization, the first two quadlets of the status never need to be cleared.

| * ieee1394: sbp2: optimize DMA direction of command ORBsStefan Richter2006-09-17
| | | | | | | | | | | | | | | | Only the driver writes ORBs, the device just reads them. Therefore PCI_DMA_BIDIRECTIONAL can be replaced by PCI_DMA_TODEVICE which may be cheaper on some architectures. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
| * ieee1394: sbp2: discard return value of sbp2_link_orb_commandStefan Richter2006-09-17

| * ieee1394: sbp2: safer last_orb and next_ORB handlingStefan Richter2006-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sbp2 initiator has two ways to tell a target's fetch agent about new command ORBs: - Write the ORB's address to the ORB_POINTER register. This must not be done while the fetch agent is active. - Put the ORB's address into the previously submitted ORB's next_ORB field and write to the DOORBELL register. This may be done while the fetch agent is active or suspended. It must not be done while the fetch agent is in reset state. Sbp2 has a last_orb pointer which indicates in what way a new command should be announced. That pointer is concurrently accessed at various occasions. Furthermore, initiator and target are accessing the next_ORB field of ORBs concurrently and asynchronously. This patch does: - Protect all initiator accesses to last_orb by sbp2_command_orb_lock. - Add pci_dma_sync_single_for_device before a previously submitted ORB's next_ORB field is overwritten. - Insert a memory barrier between when next_ORB_lo and next_ORB_hi are overwritten. Next_ORB_hi must not be updated before next_ORB_lo. - Remove the rather unspecific and now superfluous qualifier "volatile" from the next_ORB fields. - Add comments on how last_orb is connected with what is known about the target's fetch agent's state.

| * ieee1394: shrink tlabel pools, remove tpool semaphoresStefan Richter2006-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reduces the size of struct hpsb_host and also removes semaphores from ieee1394_transactions.c. On i386, struct hpsb_host shrinks from 10656 bytes to 6688 bytes. This is accomplished by - using a single wait_queue for hpsb_get_tlabel instead of many instances of semaphores, - using a single lock to serialize access to all tlabel pools (the protected code regions are small, i.e. lock contention very low), - omitting the sysfs attribute tlabels_allocations. Drawback: In the rare case that a process needs to sleep because all transaction labels for the node are temporarily exhausted, it is also woken up if a tlabel for a different node became free, checks for an available tlabel, and is put to sleep again. The check is not costly and the situation occurs extremely rarely. (Tlabels are typically only exhausted if there was no context switch to the khpsbpkt thread which recycles tlables.) Therefore the benefit of reduced tpool size outweighs this drawback. The sysfs attributes tlabels_free and tlabels_mask are not compiled anymore unless CONFIG_IEEE1394_VERBOSEDEBUG is set. The by far biggest member of struct hpsb_host, the struct csr_control csr (5272 bytes on i386), is now placed at the end of struct hpsb_host. Note, hpsb_get_tlabel calls the macro wait_event_interruptible with a condition argument which has a side effect (allocation of a tlabel and manipulation of the packet). This side effect happens only if the condition is true. The patch relies on wait_event_interruptible not evaluating the condition again after it became true.

The role of the semaphore's counter is taken over by a direct check of what was really counted: The presence of items in the list of completed requests. Notes: - raw1394_release() sleeps uninterruptibly until all requests were completed. This is the same behaviour as before the patch. - The macros wait_event and wait_event_interruptible are called with a condition argument which has a side effect, i.e. manipulation of the requests list. This side effect happens only if the condition is true. The patch relies on the fact that wait_event[_interruptible] does not evaluate the condition again after it became true. - The diffstat looks unfavorable with respect to added lines of code. However 19 of them are comments, and some are due to separation of existing code blocks into two small helper functions.

| * | [PATCH] ieee1394: skip dummy loop in build_speed_mapStefan Richter2006-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | The last loop in ieee1394 core's speed calculation is not required unless ieee1394.h::IEEE1394_SPEED_MAX is changed from its current value of 3.

| * | [PATCH] ieee1394: sbp2: enable auto spin-up for Maxtor disksStefan Richter2006-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least Maxtor OneTouch III require a "start stop unit" command after auto spin-down before the next access can proceed. This patch activates the responsible code in scsi_mod for all Maxtor SBP-2 disks. https://bugzilla.novell.com/show_bug.cgi?id=183011 Maybe that should be done for all SBP-2 disks, but better be cautious.

| * | [PATCH] ieee1394: fix cosmetic problem in speed probeStefan Richter2006-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If ieee1394.h::IEEE1394_SPEED_MAX is bigger than the actual speed of an 1394b host adapter and the speed to another 1394b node was probed, a bigger speed than actually used was kept in host->speed[n]. The only resulting problem so far was sbp2 displaying bogus values in the syslog, e.g. S3200 for actual S800 connections if IEEE1394_SPEED_MAX was S3200. But other high-level drivers which access this field could get into more trouble. (Eth1394 is the only other in-tree driver which does so. It seems it is not affected.) Nodemgr now clips this value according to the host adapter's link speed. A pointer expression in nodemgr_check_speed is also changed for clarity.
