drm/amdgpu: Fix oops when pp_funcs is unset in ACPI event

2020-04-03T21:24:10Z

On ARCTURUS and RENOIR, powerplay is not supported yet. When plug in or unplug power jack, ACPI event will issue. Then kernel NULL pointer BUG will be triggered. Check for NULL pointers before calling. Signed-off-by: Aaron Ma Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amd/powerplay: enable pp one vf mode for vega10

2019-12-11T20:22:07Z

Originally, due to the restriction from PSP and SMU, VF has to send message to hypervisor driver to handle powerplay change which is complicated and redundant. Currently, SMU and PSP can support VF to directly handle powerplay change by itself. Therefore, the old code about the handshake between VF and PF to handle powerplay will be removed and VF will use new the registers below to handshake with SMU. mmMP1_SMN_C2PMSG_101: register to handle SMU message mmMP1_SMN_C2PMSG_102: register to handle SMU parameter mmMP1_SMN_C2PMSG_103: register to handle SMU response v2: remove module parameter pp_one_vf v3: fix the parens v4: forbid vf to change smu feature v5: use hwmon_attributes_visible to skip sepicified hwmon atrribute v6: change skip condition at vega10_copy_table_to_smc Signed-off-by: Yintian Tao Acked-by: Evan Quan Reviewed-by: Kenneth Feng Signed-off-by: Alex Deucher

drm/amd/powerplay: add lock protection for swSMU APIs V2

2019-10-25T20:50:09Z

This is a quick and low risk fix. Those APIs which are exposed to other IPs or to support sysfs/hwmon interfaces or DAL will have lock protection. Meanwhile no lock protection is enforced for swSMU internal used APIs. Future optimization is needed.
