From 759eb040901af60d8a1a2b59b93805521b156cbb Mon Sep 17 00:00:00 2001 From: Sonic Zhang Date: Wed, 21 Nov 2007 17:00:32 +0800 Subject: Blackfin Serial driver: Fix bug - serial driver in PIO mode cant handle input very quickly Output as many bytes as possible in PIO tx handler. This reduce the number of tx interrupts and shorten the delay to handle rx interrupt. So, rx overrun disappears.

If the SCSI INQUIRY failed and hence __scsi_add_device failed due to a bus reset, we tried a logout and then waited for the already scheduled login work to happen. So far so good, but the generation used for the logout was outdated, hence the logout never reached the target. The target might therefore deny the subsequent relogin attempt, which would also leave the target inaccessible. Therefore fetch a fresh device->generation for the logout. Use memory barriers to prevent our plan being foiled by compiler or hardware optimizations.

The fix is obvious: Free the minor number *after* instead of *before* device_unregister(). This requires to take an additional reference of the fw_device as long as the IDR tree points to it. And while we are at it, we fix an additional race condition: fw_device_op_open() took its reference of the fw_device a little bit too late, hence was in danger to access an already invalid fw_device.

They are therefore unable to respond to SCSI INQUIRY immediately, and the SCSI core has to retry the INQUIRY. One of these retries is typically successful, and all is well. But in case of Momobay FX-3A, the INQUIRY retries tend to fail entirely. This can usually be avoided by waiting a little while after login before letting the SCSI core send the INQUIRY. The old sbp2 driver handles this more gracefully for as yet unknown reasons (perhaps because it waits for fetch agent resets to complete, unlike fw-sbp2 which quickly proceeds after requesting the agent reset). Therefore the workaround is not as much necessary for sbp2.

In those cases, __scsi_add_device succeeded and returned the pointer to the existing scsi_device. fw-sbp2 then continued orderly, except that it missed to call sbp2_cancel_orbs. SCSI core would call fw-sbp2's eh_abort_handler eventually if there had been an outstanding command. This patch avoids the needless lookups and temporary allocations in SCSI core and I/O stall and timeout until eh_abort_handler hits. Also, __scsi_add_device tolerating calls for devices which already exist is undocumented behavior on which we shouldn't rely.

Also, don't retry reconnects in this situation. The retries won't succeed either. These changes improve chances for successful re-login and shorten the period during which the logical unit is inaccessible.

They are all immediately completed with host busy status, and application clients or filesystems will break quickly. The SCSI device might even be taken offline: http://bugzilla.kernel.org/show_bug.cgi?id=9734 The only remedy seems to be to block the SCSI device until reconnect. Alas the SCSI core has no useful API to block only one logical unit i.e. the scsi_device, therefore we block the entire Scsi_Host. This currently corresponds to an SBP-2 target. In case of targets with multiple logical units, we need to satisfy the dependencies between logical units by carefully tracking the blocking state of the target and its units. We block all logical units of a target as soon as one of them needs to be blocked, and keep them blocked until all of them are ready to be unblocked. Furthermore, as the history of the old sbp2 driver has shown, the scsi_block_requests() API is a minefield with high potential of deadlocks. We therefore take extra measures to keep logical units unblocked during __scsi_add_device() and during shutdown. This avoids I/O errors during reconnect in many but alas not in all cases. There may still be errors after a re-login had to be performed. Also, some bridges have been seen to cease fetching management ORBs if I/O went on up until a bus reset. In these cases, all management ORBs time out after mgt_orb_timeout. The old sbp2 driver is less vulnerable or maybe not vulnerable to this, for as yet unknown reasons.

That's nice, but most SATA devices which need it will tell us about it in their IDENTIFY PACKET response, as bit-15 of word-62 of the returned data (as per ATA7, ATA8 specifications). So for those which specify it, we should automatically use the DMADIR bit. Otherwise, disc writing will fail by default on many SATA-ATAPI drives. This patch adds ATA_DFLAG_DMADIR and make ata_dev_configure() set it if atapi_dmadir is set or identify data indicates DMADIR is necessary. atapi_xlat() is converted to check ATA_DFLAG_DMADIR before setting DMADIR. Original patch is from Mark Lord.

This behavior has been confirmed by Marvell with a SATA analyzer. The Marvell port-multiplier apparently likes to see clean HOB information when accessing PMP registers. Since sata_mv uses PIO shadow register access, this doesn't happen automatically, as it might in a more purely FIS-based driver (eg. ahci). One way to fix this is to flag these commands with ATA_TFLAG_LBA48, forcing libata to write out the HOB fields with known (zero) values.

Use GPIO to clear all previous configurations before changing link parameters. Shut down the external PHY in case of fan failure. Reducing the MDC/MDIO clock to 2.5MHz due to problems with some devices. Resolve the flow control response according to autoneg with external PHY. Unmasking all PHY interrupts in single write to prevent a race in the interrupts order. LASI indication fixes to work with peculiarities of PHYs. Disable MAC RX to avoid a HW bug when closing the MAC under traffic. Disable parallel detection on HiGig due to HW limitation. Updating the shared memory structure to work with the current bootcode.

configuration of RX filtering needed the following corrections: Drop flags need to be set per Rx queue. Have to tell the microcode to collect drop stats, and properly wait for them to complete when going down. Sometimes we failed to detect proper completion due to a logical error in the wait loop.

Corrected order of traffic disabling to prevent race when going down under traffic. - first have the microcode drop all incoming packets - then do the slowpath stuff - only then reset the MAC Got rid of in_reset_task.

RIP [] RSP CR2: ffffffff8807b455 ---[ end trace c7366c6657fe5bed ]--- Note that this crash happened _after_ firewire-core was unloaded. The shared workqueue tried to run firewire-core's device initialization jobs or similar jobs. The fix makes sure that firewire-ohci and hence firewire-core is not unloaded before all device shutdown jobs have been completed. This is determined by the count of device initializations minus device releases. Also skip useless retries in the node initialization job if the node is to be shut down.
