drm/amdgpu:use work instead of delay-work

2017-03-30T03:53:11+00:00

no need to use a delay work since we don't know how much time hypervisor takes on FLR, so just polling and waiting in a work. Signed-off-by: Monk Liu Reviewed-by: Alex Deucher Reviewed-by: Xiangliang Yu Signed-off-by: Alex Deucher

drm/amdgpu:add lock_reset for SRIOV

2017-03-30T03:52:46+00:00

this lock is used for sriov_gpu_reset, only get this mutex can run into sriov_gpu_reset. we have couple source triggers gpu_reset for SRIOV: 1) submit timedout and trigger reset voluntarily 2) invalid instruction detected by ENGINE and trigger reset voluntarily 2) hypervisor found world switch hang and trigger flr and notify guest to do reset. all need take care and we need a mutex to protect the consistency of reset routine.
