Currently PEBS/BTS buffers are allocated when we instantiate the first event, when this fails everything fails. This is a problem because esp. BTS tries to allocate a rather large buffer (64K), which can easily fail. This patch changes the logic such that when either buffer allocation fails, we simply don't allow events that would use these facilities, but continue functioning for all other events. This logic comes from a much larger patch proposed by Stephane.

ATA devices don't send D2H Reg FIS after an successful ATA PIO data-in command. The host is supposed to take the TF and E_Status of the preceding PIO Setup FIS. Update ahci_qc_fill_rtf() such that it takes TF + E_Status from PIO Setup FIS after a successful ATA PIO data-in command. Without this patch, result_tf for such a command is filled with the content of the previous D2H Reg FIS which belongs to a previous command, which can make the command incorrectly seen as failed. * Patch updated to grab the whole TF + E_Status from PIO Setup FIS instead of just E_Status as suggested by Robert Hancock.

Now that libata provides proper cross-port EH exclusion. The SIDPR locking added by commit 213373cf (ata_piix: fix locking around SIDPR access) is no longer necessary. Remove it. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

Tejun Heo authored
In libata, the non-EH code paths should always take and release ap->lock explicitly when accessing hardware or shared data structures. However, once EH is active, it's assumed that the port is owned by EH and EH methods don't explicitly take ap->lock unless race from irq handler or other code paths are expected. However, libata EH didn't guarantee exclusion among EHs for ports of the same host. IOW, multiple EHs may execute in parallel on multiple ports of the same controller. In many cases, especially in SATA, the ports are completely independent of each other and this doesn't cause problems; however, there are cases where different ports share the same resource, which lead to obscure timing related bugs such as the one fixed by commit 213373cf (ata_piix: fix locking around SIDPR access). This patch implements exclusion among EHs of the same host. When EH begins, it acquires per-host EH ownership by calling ata_eh_acquire(). When EH finishes, the ownership is released by calling ata_eh_release(). EH ownership is also released whenever the EH thread goes to sleep from ata_msleep() or explicitly and reacquired after waking up. This ensures that while EH is actively accessing the hardware, it has exclusive access to it while allowing EHs to interleave and progress in parallel as they hit waiting stages, which dominate the time spent in EH. This achieves cross-port EH exclusion without pervasive and fragile changes while still allowing parallel EH for the most part.

The current LPM implementation has the following issues. * Operation order isn't well thought-out. e.g. HIPM should be configured after IPM in SControl is properly configured. Not the other way around. * Suspend/resume paths call ata_lpm_enable/disable() which must only be called from EH context directly. Also, ata_lpm_enable/disable() were called whether LPM was in use or not. * Implementation is per-port when it should be per-link. As a result, it can't be used for controllers with slave links or PMP. * LPM state isn't managed consistently. After a link reset for whatever reason including suspend/resume the actual LPM state would be reset leaving ap->lpm_policy inconsistent. * Generic/driver-specific logic boundary isn't clear. Currently, libahci has to mangle stuff which libata EH proper should be handling. This makes the implementation unnecessarily complex and fragile. * Tied to ALPM. Doesn't consider DIPM only cases and doesn't check whether the device allows HIPM. * Error handling isn't implemented. Given the extent of mismatch with the rest of libata, I don't think trying to fix it piecewise makes much sense. This patch reimplements LPM support. * The new implementation is per-link. The target policy is still port-wide (ap->target_lpm_policy) but all the mechanisms and states are per-link and integrate well with the rest of link abstraction and can work with slave and PMP links. * Core EH has proper control of LPM state. LPM state is reconfigured when and only when reconfiguration is necessary. It makes sure that LPM state is reset when probing for new device on the link. Controller agnostic logic is now implemented in libata EH proper and driver implementation only has to deal with controller specifics. * Proper error handling. LPM config failure is attributed to the device on the link and LPM is disabled for the link if it fails repeatedly. * ops->enable/disable_pm() are replaced with single ops->set_lpm() which takes @policy and @hints. This simplifies driver specific implementation. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

This is often seen when error handling in the init function uses functionality in the exit path.

This change enables my x86 machine to recognize and talk to a "Native 4K" SATA device. When I started working on this, I didn't know Matthew Wilcox had posted a similar patch 2 years ago: http://git.kernel.org/?p=linux/kernel/git/willy/ata.git;a=shortlog;h=refs/heads/ata-large-sectors Gwendal Grignou pointed me at the the above code and small portions of this patch include Matthew's work. That's why Mathew is first on the "Signed-off-by:". I've NOT included his use of a bitmap to determine 512 vs Native for ATA command block size - just used a simple table. And bugs are almost certainly mine. Lastly, the patch has been tested with a native 4K 'Engineering Sample' drive provided by Hitachi GST.

Currently, sata_fsl, mv and nv call ata_qc_complete() multiple times from their interrupt handlers to indicate completion of NCQ commands. This limits the visibility the libata core layer has into how commands are being executed and completed, which is necessary to support IRQ expecting in generic way. libata already has an interface to complete multiple commands at once - ata_qc_complete_multiple() which ahci and sata_sil24 already use. This patch updates the three drivers to use ata_qc_complete_multiple() too and updates comments on ata_qc_complete[_multiple]() regarding their usages with NCQ completions. This change not only provides better visibility into command execution to the core layer but also simplifies low level drivers. * sata_fsl: It already builds done_mask. Conversion is straight forward. * sata_mv: mv_process_crpb_response() no longer checks for illegal completions, it just returns whether the tag is completed or not. mv_process_crpb_entries() builds done_mask from it and passes it to ata_qc_complete_multiple() which will check for illegal completions. * sata_nv adma: Similar to sata_mv. nv_adma_check_cpb() now just returns the tag status and nv_adma_interrupt() builds done_mask from it and passes it to ata_qc_complete_multiple(). * sata_nv swncq: It already builds done_mask. Drop unnecessary illegal transition checks and call ata_qc_complete_multiple(). In the long run, it might be a good idea to make ata_qc_complete() whine if called when multiple NCQ commands are in flight.
