2020-11-09drm/gem: Use struct dma_buf_map in GEM vmap ops and convert GEM backendsThomas Zimmermann1-4/+6
This patch replaces the vmap/vunmap's use of raw pointers in GEM object functions with instances of struct dma_buf_map. GEM backends are converted as well. For most of them, this simply changes the returned type. TTM-based drivers now return information about the location of the memory, either system or I/O memory. GEM VRAM helpers and qxl now use ttm_bo_vmap() et al. Amdgpu, nouveau and radeon use drm_gem_ttm_vmap() et al instead of implementing their own vmap callbacks. v7: * init QXL cursor to mapped BO buffer (kernel test robot) v5: * update vkms after switch to shmem v4: * use ttm_bo_vmap(), drm_gem_ttm_vmap(), et al. (Daniel, Christian) * fix a trailing { in drm_gem_vmap() * remove several empty functions instead of converting them (Daniel) * comment uses of raw pointers with a TODO (Daniel) * TODO list: convert more helpers to use struct dma_buf_map Signed-off-by: Thomas Zimmermann <[email protected]> Acked-by: Christian König <[email protected]> Tested-by: Sam Ravnborg <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2020-11-06drm/<drivers>: Constify struct drm_driverDaniel Vetter1-1/+1
Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const. Only cc'ing the driver people who've not been converted (everyone else is way too much). v2: Fix one misplaced const static, should be static const (0day) v3: - Improve commit message (Sam) Acked-by: Sam Ravnborg <[email protected]> Cc: kernel test robot <[email protected]> Acked-by: Maxime Ripard <[email protected]> Reviewed-by: Alex Deucher <[email protected]> Signed-off-by: Daniel Vetter <[email protected]> Cc: Sam Ravnborg <[email protected]> Cc: Dave Airlie <[email protected]> Cc: Gerd Hoffmann <[email protected]> Cc: [email protected] Cc: Harry Wentland <[email protected]> Cc: Leo Li <[email protected]> Cc: Alex Deucher <[email protected]> Cc: Christian König <[email protected]> Cc: Eric Anholt <[email protected]> Cc: Maxime Ripard <[email protected]> Cc: Ben Skeggs <[email protected]> Cc: [email protected] Signed-off-by: Daniel Vetter <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

Because it is. Huge congrats to everyone who made this kind of refactoring happen!
