Reverted due to conflicts with the endian fix patches. Please rebase these two on top of them. Will do that .. I should have wait for the endian patch getting accepted. Sorry for that. On Mon, Jan 5, 2015 at 7:29 PM, Tejun Heo wrote: > On Mon, Jan 05, 2015 at 08:30:05AM -0500, Tejun Heo wrote:

[PATCH 2/2] ahci_xgene: Implement the workaround to support PMP enumeration and discovery for APM X-Gene SoC AHCI SATA Host Controller driver.

2015-01-05 Thread Suman Tripathi
Due to H/W errata, the controller is unable to save the PMP field fetched from command header before sending the H2D FIS. When the device returns the PMP port field in the D2H FIS, there is a mismatch and results in command completion failure. The workaround is to write the pmp value to PxFBS.DEV f
