libata: disable forced PORTS_IMPL for >= AHCI 1.3 2016-02-19T22:22:41+00:00 Tejun Heo tj@kernel.org 2016-01-15T20:13:05+00:00 f6c2bfd8a8829cc0cddefe6f952b7436b875cd18 commit 566d1827df2ef0cbe921d3d6946ac3007b1a6938 upstream. Some early controllers incorrectly reported zero ports in PORTS_IMPL register and the ahci driver fabricates PORTS_IMPL from the number of ports in those cases. This hasn't mattered but with the new nvme controllers there are cases where zero PORTS_IMPL is valid and should be honored. Disable the workaround for >= AHCI 1.3.

AHCI: Fix softreset failed issue of Port Multiplier 2016-02-19T22:22:41+00:00 Xiangliang Yu Xiangliang.Yu@amd.com 2015-11-26T12:27:02+00:00 d2b76ee2681e369a0ab38fdd7df9ea3ea94c2bd2 commit 023113d24ef9e1d2b44cb2446872b17e2b01d8b1 upstream. Current code doesn't update port value of Port Multiplier(PM) when sending FIS of softreset to device, command will fail if FBS is enabled. There are two ways to fix the issue: the first is to disable FBS before sending softreset command to PM device and the second is to update port value of PM when sending command. For the first way, i can't find any related rule in AHCI Spec. The second way can avoid disabling FBS and has better performance.

I have a ST4000DM000 disk. If Linux is booted while the disk is spun down, the command that sets transfer mode causes the disk to spin up. The spin-up takes longer than the default 5s timeout, so the command fails and timeout is reported. Fix this by increasing the timeout to 15s, which is enough for the disk to spin up.
