drm/amdgpu: fix device attribute node create failed with multi gpu

2020-05-26T19:51:45Z

the origin design will use varible of "attr->states" to save node supported states on current gpu device, but for multi gpu device, when probe second gpu device, the driver will check attribute node states from previous gpu device wthether to create attribute node. it will cause other gpu device create attribute node faild. 1. add member attr_list into amdgpu_device to link supported device attribute node. 2. add new structure "struct amdgpu_device_attr_entry{}" to track device attribute state. 3. drop member "states" from amdgpu_device_attr. v2: 1. move "attr_list" into amdgpu_pm and rename to "pm_attr_list". 2. refine create & remove device node functions parameter. fix: drm/amdgpu: optimize amdgpu device attribute code Signed-off-by: Kevin Wang Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Move EEPROM I2C adapter to amdgpu_device

2020-03-16T20:21:32Z

Puts the i2c adapter in common place for sharing by RAS and upcoming data read from FRU EEPROM feature. v2: Move i2c adapter to amdgpu_pm and rename it. v3: Move i2c adapter init to ASIC specific code and get rid of the switch case in amdgpu_device Signed-off-by: Andrey Grodzovsky Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amd/powerplay: cover the powerplay implementation details V3

2020-01-14T15:18:08Z

This can save users much troubles. As they do not actually need to care whether swSMU or traditional powerplay routine should be used. V2: apply the fixes to vi.c and cik.c also V3: squash in oops fix Signed-off-by: Evan Quan Reviewed-by: Alex Deucher 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. V2: strip the lock protection for all swSMU internal APIs Signed-off-by: Evan Quan Acked-by: Andrey Grodzovsky Acked-by: Feifei Xu Acked-by: Alex Deucher Signed-off-by: Alex Deucher
