drm/amd/pm: optimize the power related source code layout

2020-08-14T20:22:41Z

The target is to provide a clear entry point(for power routines). Also this can help to maintain a clear view about the frameworks used on different ASICs. Hopefully all these can make power part more friendly to play with. Signed-off-by: Evan Quan Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: move i2c bus lock out of ras structure

2020-07-21T19:37:40Z

It's not really ras related. It's just a lock for the bus in general. This removes the ras dependency from the smu i2c bus. Reviewed-by: Andrey Grodzovsky Signed-off-by: Alex Deucher

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
