linux-stable.git/drivers/ata, branch v3.2.52 Linux kernel stable tree libata: apply behavioral quirks to sil3826 PMP 2013-09-10T00:57:26+00:00 Terry Suereth terry.suereth@gmail.com 2013-08-17T19:53:12+00:00 343077dc5d8ec1fe65caf734d5d4205ac35b3ab2 commit 8ffff94d20b7eb446e848e0046107d51b17a20a8 upstream. Fixing support for the Silicon Image 3826 port multiplier, by applying to it the same quirks applied to the Silicon Image 3726. Specifically fixes the repeated timeout/reset process which previously afflicted the 3726, as described from line 290.

libata: make it clear that sata_inic162x is experimental 2013-09-10T00:57:04+00:00 Tejun Heo tj@kernel.org 2013-07-22T20:53:36+00:00 d2f1837b4bfeca92b188de170a6abd1ee4514dbc commit bb9696192826a7d9279caf872e95b41bc26c7eff upstream. sata_inic162x never reached a state where it's reliable enough for production use and data corruption is a relatively common occurrence. Make the driver generate warning about the issues and mark the Kconfig option as experimental. If the situation doesn't improve, we'd be better off making it depend on CONFIG_BROKEN.

libata: skip SRST for all SIMG [34]7x port-multipliers 2013-07-27T04:34:09+00:00 Tejun Heo tj@kernel.org 2013-06-11T07:11:36+00:00 c2ecb14d22b1e99a9dcdef8d20a37762c45e6e67 commit 7a87718d92760fc688628ad6a430643dafa16f1f upstream. For some reason, a lot of port-multipliers have issues with softreset. SIMG [34]7x series port-multipliers have been quite erratic in this regard. I recall that it was better with some firmware revisions and the current list of quirks worked fine for a while. I think it got worse with later firmwares or maybe my test coverage wasn't good enough. Anyways, HPA is reporting that his 3726 setup suffers SRST failures and then the PMP gets confused and fails to probe the last port. The hope was that we try to stick to the standard as much as possible and soonish the PMPs and their firmwares will improve in quality, so the quirk list was kept to minimum. Well, it seems like that's never gonna happen. Let's set NO_SRST for all [34]7x PMPs so that whatever remaining userbase of the device suffer the least. Maybe we should do the same for 57xx's but unfortunately I don't have any device left to test and I'm not even sure 57xx's have ever been made widely available, so let's leave those alone for now.
