The logic behind it was to be softer to devices;\nhowever, this doesn\u0027t really help much. Rationales for the change:\n\n* BIOS may freeze lock certain things during boot and softreset can\u0027t\n unlock those. This by itself is okay but during operation PHY event\n or other error conditions can trigger hardreset and the device may\n end up with different configuration.\n\n For example, after a hardreset, previously unlockable HPA can be\n unlocked resulting in different device size and thus revalidation\n failure. Similar condition can occur during or after resume.\n\n* Certain ATAPI devices require hardreset to recover after certain\n error conditions. On PATA, this is done by issuing the DEVICE RESET\n command. On SATA, COMRESET has equivalent effect. The problem is\n that DEVICE RESET needs its own execution protocol.\n\n For SFF controllers with bare TF access, it can be easily\n implemented but more advanced controllers (e.g. ahci and sata_sil24)\n require specialized implementations. Simply using hardreset solves\n the problem nicely.\n\n* COMRESET initialization sequence is the norm in SATA land and many\n SATA devices don\u0027t work properly if only SRST is used. For example,\n some PMPs behave this way and libata works around by always issuing\n hardreset if the host supports PMP.\n\n Like the above example, libata has developed a number of mechanisms\n aiming to promote softreset to hardreset if softreset is not going\n to work. This approach is time consuming and error prone.\n\n Also, note that, dependingon how you read the specs, it could be\n argued that PMP fan-out ports require COMRESET to start operation.\n In fact, all the PMPs on the market except one don\u0027t work properly\n if COMRESET is not issued to fan-out ports after PMP reset.\n\n* COMRESET is an integral part of SATA connection and any working\n device should be able to handle COMRESET properly. After all, it\u0027s\n the way to signal hardreset during reboot. This is the most used\n and recommended (at least by the ahci spec) method of resetting\n devices.\n\nSo, this patch makes libata prefer hardreset over softreset by making\nthe following changes.\n\n* Rename ATA_EH_RESET_MASK to ATA_EH_RESET and use it whereever\n ATA_EH_{SOFT|HARD}RESET used to be used. ATA_EH_{SOFT|HARD}RESET is\n now only used to tell prereset whether soft or hard reset will be\n issued.\n\n* Strip out now unneeded promote-to-hardreset logics from\n ata_eh_reset(), ata_std_prereset(), sata_pmp_std_prereset() and\n other places.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\n" }, { "commit": "526917641aa50eb852591cc3953a92374bedc836", "tree": "38d2033ed637a54ff607e4c1adf861fb3b90f44a", "parents": [ "a34c4e98367965402134f2e66c3cdc4416f109e4" ], "author": { "name": "FUJITA Tomonori", "email": "fujita.tomonori@lab.ntt.co.jp", "time": "Tue Mar 25 09:26:51 2008 +0900" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@HansenPartnership.com", "time": "Mon Apr 07 12:19:02 2008 -0500" }, "message": "[SCSI] libata: use scsi_build_sense_buffer\n\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Jeff Garzik \u003cjeff@garzik.org\u003e\nCc: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\n" }, { "commit": "aacda37538e7f9cf2148eedf3766239829e51ba4", "tree": "0206d2db8ce636aadabf8e3effd1ee3114ccff2a", "parents": [ "cc7feea39bed2951cc29af3ad642f39a99dfe8d3" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Tue Mar 18 17:47:43 2008 +0900" }, "committer": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Mon Mar 24 22:09:12 2008 -0400" }, "message": "libata: implement ata_qc_raw_nbytes()\n\nImplement ata_qc_raw_nbytes() which determines the raw user-requested\nsize of a PC command.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n" }, { "commit": "e3790c7d42a545e8fe8b38b513613ca96687b670", "tree": "0b849ba46007c4d7f7a34271a76d58e7406cbad7", "parents": [ "7a85f8896f4b4a4a0249563b92af9e3161a6b467" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Tue Mar 04 11:18:17 2008 +0100" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Tue Mar 04 11:18:17 2008 +0100" }, "message": "block: separate out padding from alignment\n\nBlock layer alignment was used for two different purposes - memory\nalignment and padding.
