YangtzeSataResetService implements the SataSetMaxGen2 double. The value should be only set, if the condition is met. For testing, add FchParams_env->Sata.SataMode.SataSetMaxGen2 = FALSE; to your BiosCallOuts.c, which enables GEN3 for the SATA ports. Patch is tested with bap/e20xx board, Lubuntu 16.04 Kernel 4.4. $ dmesg | grep ahci #before patch ahci 0000:00:11.0: AHCI 0001.0300 32 slots 2 ports 3 Gbps 0x3 impl SATA mode $ dmesg | grep ahci #after patch ahci 0000:00:11.0: AHCI 0001.0300 32 slots 2 ports 6 Gbps 0x3 impl SATA mode BUG=None BRANCH=None TEST=None Change-Id: I17a493b876a4be3236736b2116b331e465b159af Original-Signed-off-by: Fabian Kunkel <fabi@adv.bruhnspace.com> Original-Reviewed-on: https://review.coreboot.org/15728 Original-Tested-by: build bot (Jenkins) Original-Reviewed-by: Nico Huber <nico.h@gmx.de> Original-Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Signed-off-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/362842 Reviewed-by: Furquan Shaikh <furquan@chromium.org> |
