2020-11-24drm/shmem-helper: Use cached mappings by defaultThomas Zimmermann1-2/+2
SHMEM-buffer backing storage is allocated from system memory; which is typically cachable. The default mode for SHMEM objects is writecombine though. Unify SHMEM semantics by defaulting to cached mappings. The exception is pages imported via dma-buf. DMA memory is usually not cached. DRM drivers that require write-combined mappings set the map_wc flag in struct drm_gem_shmem_object to true. This currently affects lima, panfrost and v3d. The drivers mgag200, udl, virtio and vkms continue to use default shmem mappings. The drivers cirrus and gm12u320 change caching flags. Both used writecombine and now switch over to shmem defaults. Both drivers use SHMEM objects as shadow buffers for internal video memory, so cached mappings will not affect them negatively. v3: * set value of shmem pointer before dereferencing it in __drm_gem_shmem_create() (Dan, kernel test robot) v2: * recreate patch on top of latest SHMEM helpers * update lima, panfrost, v3d to select writecombine (Daniel, Rob) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Maxime Ripard <mripard@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20201117133156.26822-2-tzimmermann@suse.de

2020-11-11drm/ttm: add multihop infrastrucutre (v3)Dave Airlie1-1/+6
Currently drivers get called to move a buffer, but if they have to move it temporarily through another space (SYSTEM->VRAM via TT) then they can end up with a lot of ttm->driver->ttm call stacks, if the temprorary space moves requires eviction. Instead of letting the driver do all the placement/space for the temporary, allow it to report back (-EMULTIHOP) and a placement (hop) to the move code, which will then do the temporary move, and the correct placement move afterwards. This removes a lot of code from drivers, at the expense of adding some midlayering. I've some further ideas on how to turn it inside out, but I think this is a good solution to the call stack problems. v2: separate out the driver patches, add WARN for getting MULTHOP in paths we shouldn't (Daniel) v3: use memset (Christian) Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: hristian König <christian.koenig@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201109005432.861936-2-airlied@gmail.com

2020-11-09drm/cma-helper: Make default object functions the defaultThomas Zimmermann1-5/+0
As GEM object functions are now mandatory, DRM drivers based on CMA helpers either set them in their implementation of gem_create_object, or use the default via drm_gem_cma_create_object_default_funcs(). Simplify this by setting the default CMA object functions for all objects that don't have any functions of their own. Follows the pattern of similar code in SHMEM and VRAM helpers. The function drm_gem_cma_create_object_default_funcs() is redundant and therefore being removed.

2020-11-09drm/fb_helper: Support framebuffers in I/O memoryThomas Zimmermann1-12/+0
At least sparc64 requires I/O-specific access to framebuffers. This patch updates the fbdev console accordingly. For drivers with direct access to the framebuffer memory, the callback functions in struct fb_ops test for the type of memory and call the rsp fb_sys_ of fb_cfb_ functions. Read and write operations are implemented internally by DRM's fbdev helper. For drivers that employ a shadow buffer, fbdev's blit function retrieves the framebuffer address as struct dma_buf_map, and uses dma_buf_map interfaces to access the buffer. The bochs driver on sparc64 uses a workaround to flag the framebuffer as I/O memory and avoid a HW exception. With the introduction of struct dma_buf_map, this is not required any longer. The patch removes the rsp code from both, bochs and fbdev. v7: * use min_t(size_t,) (kernel test robot) * return the number of bytes read/written, if any (fbdev testcase) v5: * implement fb_read/fb_write internally (Daniel, Sam) v4: * move dma_buf_map changes into separate patch (Daniel) * TODO list: comment on fbdev updates (Daniel) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Tested-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20201103093015.1063-11-tzimmermann@suse.de

2020-10-29drm/ttm: new TT backend allocation pool v3Christian König2-0/+93
This replaces the spaghetti code in the two existing page pools. First of all depending on the allocation size it is between 3 (1GiB) and 5 (1MiB) times faster than the old implementation. It makes better use of buddy pages to allow for larger physical contiguous allocations which should result in better TLB utilization at least for amdgpu. Instead of a completely braindead approach of filling the pool with one CPU while another one is trying to shrink it we only give back freed pages. This also results in much less locking contention and a trylock free MM shrinker callback, so we can guarantee that pages are given back to the system when needed. Downside of this is that it takes longer for many small allocations until the pool is filled up. We could address this, but I couldn't find an use case where this actually matters. We also don't bother freeing large chunks of pages any more since the CPU overhead in that path isn't really that important. The sysfs files are replaced with a single module parameter, allowing users to override how many pages should be globally pooled in TTM. This unfortunately breaks the UAPI slightly, but as far as we know nobody ever depended on this. Zeroing memory coming from the pool was handled inconsistently. The alloc_pages() based pool was zeroing it, the dma_alloc_attr() based one wasn't. For now the new implementation isn't zeroing pages from the pool either and only sets the __GFP_ZERO flag when necessary. The implementation has only 768 lines of code compared to the over 2600 of the old one, and also allows for saving quite a bunch of code in the drivers since we don't need specialized handling there any more based on kernel config. Additional to all of that there was a neat bug with IOMMU, coherent DMA mappings and huge pages which is now fixed in the new code as well. v2: make ttm_pool_apply_caching static as reported by the kernel bot, add some more checks v3: fix some more checkpatch.pl warnings Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Madhav Chauhan <madhav.chauhan@amd.com> Tested-by: Huang Rui <ray.huang@amd.com> Link: https://patchwork.freedesktop.org/patch/397080/?series=83051&rev=1

2020-10-21drm: Introduce plane and CRTC scaling filter propertiesPankaj Bharadiya2-0/+37
Introduce per-plane and per-CRTC scaling filter properties to allow userspace to select the driver's default scaling filter or Nearest-neighbor(NN) filter for upscaling operations on CRTC and plane. Drivers can set up this property for a plane by calling drm_plane_create_scaling_filter() and for a CRTC by calling drm_crtc_create_scaling_filter(). NN filter works by filling in the missing color values in the upscaled image with that of the coordinate-mapped nearest source pixel value. NN filter for integer multiple scaling can be particularly useful for for pixel art games that rely on sharp, blocky images to deliver their distinctive look. changes since: v6: * Move property doc to existing "Standard CRTC Properties" and "Plane Composition Properties" doc comments (Simon) changes since v3: * Refactor code, add new function for common code (Ville) changes since v2: * Create per-plane and per-CRTC scaling filter property (Ville) changes since v1: * None changes since RFC: * Add separate properties for plane and CRTC (Ville) Link: https://github.com/xbmc/xbmc/pull/18194 Link: https://github.com/xbmc/xbmc/pull/18567 Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Acked-by: Simon Ser <contact@emersion.fr> Acked-by: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Pankaj Bharadiya <pankaj.laxminarayan.bharadiya@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201020161427.6941-2-pankaj.laxminarayan.bharadiya@intel.com
