It\u0027s done this way for two reasons.\n\nFirst, the ops table already contained too many methods and adding\nfour more of them would noticeably increase the amount of necessary\nboilerplate code all over low level drivers.\n\nSecond, as -\u003eerror_handler uses those reset methods, it can get\nconfusing. ie.

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": "1892225f788a73beae2ec26f6f2fa4cd2e5868d0", "tree": "b177522cdb32df406a8f0ee084e1170383f6daaf", "parents": [ "aeb74914ef0e6746f15b11c0399048de9c5c05b8" ], "author": { "name": "Adrian Bunk", "email": "bunk@kernel.org", "time": "Fri Apr 11 20:28:27 2008 +0300" }, "committer": { "name": "Jeff Garzik", "email": "jgarzik@redhat.com", "time": "Sat Apr 12 00:16:49 2008 -0400" }, "message": "[libata] make ali_atapi_dma static\n\nThis patch makes the needlessly global ali_atapi_dma static.\n\nSigned-off-by: Adrian Bunk \u003cbunk@kernel.org\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n" }, { "commit": "aeb74914ef0e6746f15b11c0399048de9c5c05b8", "tree": "9de73c3f15118beef91aac63168ca6a36c389306", "parents": [ "f4be31ec9690cfe6e94fcbed6ae60a6a38b3c3ed" ], "author": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Sat Apr 12 00:11:35 2008 -0400" }, "committer": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Sat Apr 12 00:11:35 2008 -0400" }, "message": "[libata] sata_svw: fix reversed port count\n\nAccording to Broadcom, two chips have their port counts flipped.

(Promise\u0027s driver does this too.)\n\nThis patch adds SATA-specific versions of -\u003efreeze() and -\u003ethaw()\nthat also disable and enable hotplug events. PATA ports continue\nto use the old versions of -\u003efreeze() and -\u003ethaw().\n\nAccesses to the hotplug register must be serialised via host-\u003elock.\nWe rely on ap-\u003elock \u003d\u003d \u0026ap-\u003ehost-\u003elock and that libata takes this\nlock before -\u003efreeze() and -\u003ethaw().
