2022-04-07dma-buf: add enum dma_resv_usage v4Christian König
This change adds the dma_resv_usage enum and allows us to specify why a dma_resv object is queried for its containing fences. Additional to that a dma_resv_usage_rw() helper function is added to aid retrieving the fences for a read or write userspace submission. This is then deployed to the different query functions of the dma_resv object and all of their users. When the write paratermer was previously true we now use DMA_RESV_USAGE_WRITE and DMA_RESV_USAGE_READ otherwise. v2: add KERNEL/OTHER in separate patch v3: some kerneldoc suggestions by Daniel v4: some more kerneldoc suggestions by Daniel, fix missing cases lost in the rebase pointed out by Bas.

2021-06-04radeon: use memcpy_to/fromio for UVD fw uploadChen Li
I met a gpu addr bug recently and the kernel log tells me the pc is memcpy/memset and link register is radeon_uvd_resume. As we know, in some architectures, optimized memcpy/memset may not work well on device memory. Trival memcpy_toio/memset_io can fix this problem. BTW, amdgpu has already done it in: commit ba0b2275a678 ("drm/amdgpu: use memcpy_to/fromio for UVD fw upload"), that's why it has no this issue on the same gpu and platform.

2014-02-28drm/radeon: use variable UVD clocksAlex Deucher
Now that Christian fixed the performance problems with the feedback buffer in mesa, we can enable variable UVD clocks. There are multiple UVD power states associated with different types and numbers of streams. This uses the appropriate state based on that information rather than always using the fastest UVD clocks which saves some power. One possible downside is that this may adversely affect decode benchmarks since these power states target specific playback requirements rather than maximum performance. If that becomes an issue, we can add a sysfs attribute to force the max UVD state. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>
