drm/amdgpu: free handles after fini the context

2016-07-29T18:37:05Z

This will make sure all the submissions from different contexts gets finished, and then we close the session and free up the handles. This will fix the issue that session clean-up is not get done properly, when with the command `kill -9' Signed-off-by: Leo Liu Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Forbid runtime pm on driver unload

2016-06-24T06:49:32Z

The PCI core calls pm_runtime_forbid() on device probe in pci_pm_init(), making this the default state when amdgpu is loaded. amdgpu_driver_load_kms() therefore calls pm_runtime_allow(), but there's no pm_runtime_forbid() in amdgpu_driver_unload_kms() to balance it. Add it so that we leave the device in the same state that we found it. This isn't a bug, it's just good housekeeping. When amdgpu is first loaded with runpm=1, then unloaded and loaded again with runpm=0, pm_runtime_forbid() will be called from amdgpu_pmops_runtime_idle() or amdgpu_pmops_runtime_suspend(), so the behaviour is correct. If there ever is a third party driver for AMD cards, this commit avoids that it has to clean up behind amdgpu.

drm/amdgpu: Don't leak runtime pm ref on driver load

2016-06-24T06:49:31Z

If an error occurs in amdgpu_device_init() after adev->rmmio has been set, its caller amdgpu_driver_load_kms() will skip runtime pm initialization and call amdgpu_driver_unload_kms(), which acquires a runtime pm ref that is leaked. Balance by releasing a runtime pm ref in the error path of amdgpu_driver_load_kms().

drm/amdgpu: Don't leak runtime pm ref on driver unload

2016-06-24T06:49:30Z

amdgpu_driver_load_kms() calls pm_runtime_put_autosuspend() if amdgpu_device_is_px(dev), but amdgpu_driver_unload_kms() calls pm_runtime_get_sync() unconditionally. We therefore leak a runtime pm ref whenever amdgpu is unloaded on a non-PX machine or if runpm=0. The GPU will subsequently never runtime suspend after loading amdgpu again. Fix by taking the runtime pm ref under the same condition that it was released on driver load.
