2020-02-06drm/vram: Add helpers to validate a display mode's memory requirementsThomas Zimmermann3-23/+71
Devices with low amount of dedicated video memory may not be able to use all possible display modes, as the framebuffers may not fit into VRAM. The new helper function drm_vram_helper_mode_valid() implements a simple test to sort out all display modes that can not be used in any case. Drivers should call this function from struct drm_mode_config_funcs.mode_valid. The functionality was originally implemented by the ast driver, which is being converted as well. v2: * WARN_ON if VRAM memory manager has not been initialized * documentation fixes * unexported drm_vram_helper_mode_valid_internal() Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20200203155258.9346-2-tzimmermann@suse.de

2020-02-05drm: Remove the dma_alloc_coherent wrapper for internal usageChris Wilson4-36/+15
Internally for "consistent" maps, we create a temporary struct drm_dma_handle in order to use our own dma_alloc_coherent wrapper then destroy the temporary wrap. Simplify our logic by removing the temporary wrapper!

2020-02-05drm: Remove PageReserved manipulation from drm_pci_allocChris Wilson1-21/+2
drm_pci_alloc/drm_pci_free are very thin wrappers around the core dma facilities, and we have no special reason within the drm layer to behave differently. In particular, since commit de09d31dd38a50fdce106c15abd68432eebbd014 Author: Kirill A. Shutemov <kirill.shutemov@linux.intel.com> Date: Fri Jan 15 16:51:42 2016 -0800 page-flags: define PG_reserved behavior on compound pages As far as I can see there's no users of PG_reserved on compound pages. Let's use PF_NO_COMPOUND here. it has been illegal to combine GFP_COMP with SetPageReserved, so lets stop doing both and leave the dma layer to its own devices.
