2008-04-25sata_mv: re-enable hotplug, update TODO listMark Lord1-50/+29
Re-enable hotplug, now that the interrupt/error handling are mostly sane. Also update the TODO list at the top. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-04-25sata_mv: leave SError bits untouched in mv_err_intrMark Lord1-21/+19
Here it is again, minus the checkpatch.pl complaint: Rework mv_err_intr() to leave the SError bits as-is, so that libata-eh has a chance to see/use them. We originally thought that clearing them here was necessary before writing back to edma_err_cause (per the Marvell datasheets), but we will end up reseting the chip regardless in those cases.

2008-04-25sata_mv: more interrupt handling reworkMark Lord1-48/+58
Continue fixing the interrupt handling logic. Get rid of mv_intr_pio(), by using ata_sff_host_intr() for PIO.. Add a mv_unexpected_intr() catch-all for "impossible" scenarios, where we get an interrupt that shouldn't have happened (never seen in testing, but just in case..). Rearrange the logic so that we always process completed response queue entries before looking for other events, This avoids having to re-issue commands that had already succeeded. As part of this, we split out some duplicated functionality into a new function, mv_get_active_qc(). Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-04-25sata_mv: tidy host controller interrupt handlingMark Lord1-62/+45
Tidy up host controller interrupt handling, by moving the weirdo bit shifting from mv_interrupt() to mv_host_intr(). This lets us take advantage of the MV_PORT_TO_SHIFT_AND_HARDPORT() macro from an earlier patch to greatly simplify the port numbering logic. Also, defer reading the hc_irq_cause (one per hc) until it is actually proven to be needed. This may save a microsecond or so per interrupt, on average (a later patchset will further reduce unnecessary register reads throughout the driver). Apart from that, we still leave the actual IRQ handling logic alone. Subsequent patches in this series will address that.

2008-04-25sata_mv: simplify request/response queue handlingMark Lord1-53/+56
Try and simplify handling of the request/response queues. Maintain the cached copies of queue indexes in a fully-masked state, rather than having each use of them have to do the masking. Split off handling of a single crpb response into a separate function, to reduce complexity in the main mv_process_crpb_entries() routine. Ignore the rarely-valid error bits from the crpb status field, as we already handle that information in mv_err_intr(). For now, preserve the rest of the original logic. A later patch will deal with fixing that separately. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-04-25sata_mv: simplify freeze/thaw bit-shift calculationsMark Lord1-16/+26
Introduce the MV_PORT_TO_SHIFT_AND_HARDPORT() macro, to centralize/simplify various scattered bits of logic for calculating bit shifts and the like. Some of the places that do this get it wrong, too, so consolidating the algorithm at one place will help keep the code correct. For now, we use the new macro in mv_eh_{freeze,thaw}. A subsequent patch will re-use this in the interrupt handlers Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-04-25libata-eh set tf flags in NCQ EH result_tfMark Lord1-0/+1
Fix mis-reporting of NCQ errors by ensuring that result_tf->flags is properly initialized in libata-eh. This allows ata_gen_ata_sense() to report the failed block number correctly to SCSI after a media error during NCQ. This patch may also be a candidate for backporting to earlier kernels. Without this fix, SCSI will fail I/O on the entire request rather than just the bad sector. That can be bad for a request that was merged from many independent read reads from different tasks.

2008-04-25sata_sis: SCR accessors return -EINVAL when requested SCR isn't availableTejun Heo1-5/+7
sis_scr_cfg_read() can't access SError and was incorrectly returning -1 instead of -EINVAL. This went unnoticed because SError used to be cleared in @postreset() and it didn't care about how scr_read() failed but commit ac371987 moved SError clearing into sata_link_resume() and SCR access failure other than -EINVAL is considered an error condition and exposes the incorrect return value bug as detection failure. Fix it. Also, scsi_scr_cfg_write() was incorrectly returning 0 after it ignored the request to write to SError. Make it also return -EINVAL. This was bisected and reported by Patrick McHardy.

Frank Bennett reported that ivtv was causing skype to crash. With help from one of their developers he showed it was a kernel problem. VIDIOCGCAP copies a name into a fixed length buffer - ivtv uses names that are too long and does not truncate them so corrupts a few bytes of the app data area.

And worse still, actual effort is being expended to sweep this change throughout the kernel source tree. Don't these people have better things to do? So...

2008-04-24V4L/DVB (7714): pvrusb2: Fix hang on module removalMike Isely1-1/+18
The pvrusb2 driver was getting had by this scenario: 1. Task A calls kthread_stop() for task B. 2. Before exiting, then Task B calls kthread_stop() for task C. The problem is, kthread_stop() wants to allocate an internal resource to itself (i.e. acquire a lock), which won't be released until kthread_stop() returns. But kthread_stop() won't return until task B is dead. But task B won't die until it finishes its call to kthread_stop() for task C, and that will block waiting on the resource already allocated inside task A. Deadlock. With the pvrusb2 driver, task A is the caller to pvr_exit(), task B is the control thread run inside of pvrusb2-context.c, and task C is any worker thread run inside of pvrusb2-hdw.c. This problem got introduced by the previous threading setup change, which was itself an attempt to fix a module tear-down race (which it actually did fix). The lesson here is that a task being waited on as part of a kthread_stop() simply cannot be allow to also issue a kthread_stop() - or we make sure not to issue the enclosing kthread_stop() until we know that the inner kthread_stop() has completed first. The solution for the pvrusb2 driver is some hackish code which changes the main control thread tear down into a two step process. This then makes it possible to delay issuing the kthread_stop() on the control thread until after we know that everything has been torn down first. (And yes, we really need that kthread_stop() because it's the only way to safely guarantee that a module-referencing kernel thread has safely returned back out of the module before we finally remove the module.)

2008-04-24V4L/DVB (7711): pvrusb2: Fix race on module unloadMike Isely3-51/+174
The pvrusb2 driver - for basically forever - was not enforcing a proper module tear-down. Kernel threads are used inside the driver and all must be gone before the module can be safely removed. This changeset reimplements a chunk of pvrusb2-context.c to enforce this correctly. Unfortunately this is not a simple fix. The new implementation also cuts back on kernel thread usage; instead of there being 1 control thread per instance now it's just 1 control thread shared by all instances. (By dropping to a single thread then the module exit function can block on its shutdown and the thread itself can monitor and cleanly shut down all of the other instances first.)

2008-04-24V4L/DVB (7702): pvrusb2: Rework USB streaming start/stop executionMike Isely1-15/+37
The commands to start / stop USB streaming for an analog device are fairly standard, owing to the fact that all supported devices apparently started from the same common reference design. However with digital mode, the commands seem to vary by vendor. This change makes that variance more explicit. It also cleans up a related problem for OnAir devices which prevented digital mode from working at all.
