      "message": "ahci: start engine only during soft/hard resets\n\nThis is another attempt at fixing the same problem that 270dac35c2\n(libata: ahci_start_engine compliant to AHCI spec) tried to solve.\nUnfortunately, 270dac35c2 created regressions for a lot more common\ncontrollers and got reverted.\n\nThis specific AHCI IP block becomes a brick if the DMA engine is\nstarted while DRQ is set.  It is not possible to avoid the condition\ncompletely but the most common occurrence is caused by spurious use of\nahci_start_engine() from ahci_start_port() during init sequence.\n\nDMA engine is started after both soft and hard resets and\nahci_start_port() is always followed by resets, so there is no reason\nto start DMA engine from ahci_start_port().\n\nThis patch removes ahci_start_engine() invocation from\nahci_start_port().  This change makes failure path of\nahci_port_suspend() leave engine stopped without following resets.\nThis is resolved by replacing ahci_start_port() call with\nata_port_freeze() which forces resets afterwards, which is the better\nbehavior anyway.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReported-by: Brian Norris \u003ccomputersforpeace@gmail.com\u003e\nReported-by: Jian Peng \u003cjipeng2005@gmail.com\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n"

      "message": "libata: reimplement link power management\n\nThe current LPM implementation has the following issues.\n\n* Operation order isn\u0027t well thought-out.  e.g. HIPM should be\n  configured after IPM in SControl is properly configured.  Not the\n  other way around.\n\n* Suspend/resume paths call ata_lpm_enable/disable() which must only\n  be called from EH context directly.  Also, ata_lpm_enable/disable()\n  were called whether LPM was in use or not.\n\n* Implementation is per-port when it should be per-link.  As a result,\n  it can\u0027t be used for controllers with slave links or PMP.\n\n* LPM state isn\u0027t managed consistently.  After a link reset for\n  whatever reason including suspend/resume the actual LPM state would\n  be reset leaving ap-\u003elpm_policy inconsistent.\n\n* Generic/driver-specific logic boundary isn\u0027t clear.  Currently,\n  libahci has to mangle stuff which libata EH proper should be\n  handling.  This makes the implementation unnecessarily complex and\n  fragile.\n\n* Tied to ALPM.  Doesn\u0027t consider DIPM only cases and doesn\u0027t check\n  whether the device allows HIPM.\n\n* Error handling isn\u0027t implemented.\n\nGiven the extent of mismatch with the rest of libata, I don\u0027t think\ntrying to fix it piecewise makes much sense.  This patch reimplements\nLPM support.\n\n* The new implementation is per-link.  The target policy is still\n  port-wide (ap-\u003etarget_lpm_policy) but all the mechanisms and states\n  are per-link and integrate well with the rest of link abstraction\n  and can work with slave and PMP links.\n\n* Core EH has proper control of LPM state.  LPM state is reconfigured\n  when and only when reconfiguration is necessary.  It makes sure that\n  LPM state is reset when probing for new device on the link.\n  Controller agnostic logic is now implemented in libata EH proper and\n  driver implementation only has to deal with controller specifics.\n\n* Proper error handling.  LPM config failure is attributed to the\n  device on the link and LPM is disabled for the link if it fails\n  repeatedly.\n\n* ops-\u003eenable/disable_pm() are replaced with single ops-\u003eset_lpm()\n  which takes @policy and @hints.  This simplifies driver specific\n  implementation.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n"
