When EH\nbegins, it acquires per-host EH ownership by calling ata_eh_acquire().\nWhen EH finishes, the ownership is released by calling\nata_eh_release(). EH ownership is also released whenever the EH\nthread goes to sleep from ata_msleep() or explicitly and reacquired\nafter waking up.\n\nThis ensures that while EH is actively accessing the hardware, it has\nexclusive access to it while allowing EHs to interleave and progress\nin parallel as they hit waiting stages, which dominate the time spent\nin EH.

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.

In libata, this timeout is determined by\nATA_TMOUT_FF_WAIT. Quantum GoVault is the worst requring about 2s for\nreliable detection. However, because 2s 0xff timeout can introduce\nrather long spurious delay during boot, libata has been compromising\nat the next longest timeout of 800ms for HHD424020F7SV00 iVDR drive.\n\nNow that parallel scan is in place for common drivers, libata can\nafford 2s 0xff timeout. Use 2s 0xff timeout if parallel scan is\nenabled.\n\nPlease note that the chance of spurious wait is pretty slim w/ working\nSCR access so this will only affect SATA controllers w/o SCR access\nwhich isn\u0027t too common these days.\n\nPlease read the following thread for more information on the GoVault\ndrive.\n\n http://thread.gmane.org/gmane.linux.ide/14545/focus\u003d14663\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Gary Hade \u003cgaryhade@us.ibm.com\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n" }, { "commit": "294440887b32c58d220fb54b73b7a58079b78f20", "tree": "83ad03746ca4e7e34fb74cdb2e42b075e085d4da", "parents": [ "4f2c774856708bccecb74c0e6296e9e2c9136ee1" ], "author": { "name": "Sergei Shtylyov", "email": "sshtylyov@ru.mvista.com", "time": "Thu Apr 22 20:03:35 2010 +0400" }, "committer": { "name": "Jeff Garzik", "email": "jgarzik@redhat.com", "time": "Fri May 14 17:08:02 2010 -0400" }, "message": "libata-sff: kill unused ata_bus_reset()\n\n... since I see no callers of it.\n\nSigned-off-by: Sergei Shtylyov \u003csshtylyov@ru.mvista.com\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n" }, { "commit": "445d211b0da4e9a6e6d576edff85085c2aaf53df", "tree": "039ade5b49cb0bbd388babc369f28f541c76ec96", "parents": [ "68b0ddb289220b6d4d865be128939663be34959d" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Mon Apr 05 10:33:13 2010 +0900" }, "committer": { "name": "Jeff Garzik", "email": "jgarzik@redhat.com", "time": "Tue Apr 06 10:55:33 2010 -0400" }, "message": "libata: unlock HPA if device shrunk\n\nSome BIOSes don\u0027t configure HPA during boot but do so while resuming.\nThis causes harddrives to shrink during resume making libata detach\nand reattach them.
