drm/ttm: cleanup BO size handling v3

2020-12-14T13:20:46Z

Based on an idea from Dave, but cleaned up a bit. We had multiple fields for essentially the same thing. Now bo->base.size is the original size of the BO in arbitrary units, usually bytes. bo->mem.num_pages is the size in number of pages in the resource domain of bo->mem.mem_type. v2: use the GEM object size instead of the BO size v3: fix printks in some places Signed-off-by: Christian König Reviewed-by: Huang Rui (v1) Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/406831/

drm/amdgpu: free the pre-OS console framebuffer after the first modeset

2020-12-09T04:06:30Z

Rather than in late_init to avoid race conditions between freeing the buffers and the initial modeset. Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/ttm/drivers: remove unecessary ttm_module.h include v2

2020-12-01T16:43:46Z

ttm_module.h deals with internals of TTM and should never be include outside of it. v2: also move the file around Signed-off-by: Christian König Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/404885/

drm/prime: split array import functions v4

2020-11-30T14:00:45Z

Mapping the imported pages of a DMA-buf into an userspace process doesn't work as expected. But we have reoccurring requests on this approach, so split the functions for this and document that dma_buf_mmap() needs to be used instead. v2: split it into two functions v3: rebased on latest changes v4: update commit message a bit Signed-off-by: Christian König Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/403838/
