drm/legacy: Fix type for drm_local_map.offset

2020-04-09T07:06:45Z

drm_local_map.offset is not only used for resource_size_t but also dma_addr_t which may be of different sizes.

drm: Remove the dma_alloc_coherent wrapper for internal usage

2020-02-04T23:57:26Z

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!

drm/pci: Hide legacy PCI functions from non-legacy code

2019-12-05T07:44:04Z

Declarations of drm_legacy_pci_{init,exit}() are being moved to drm_legacy.h. CONFIG_DRM_LEGACY protects the implementation.

drm: un-inline drm_legacy_findmap()

2019-01-02T09:37:11Z

Un-inline drm_legacy_findmap() to not depend on struct drm_device definition within drm_legacy.h, so that a forward declaration suffices. Also include drm_hashtab.h in drm_legacy.h to make it more self-contained. Make it easier to drop drmP.h includes. v2: avoid including drm_device.h by un-inlining (Daniel) [Updated commit message per Laurent's review while applying.] Cc: Sam Ravnborg Cc: Daniel Vetter Cc: Laurent Pinchart Reviewed-by: Daniel Vetter Reviewed-by: Laurent Pinchart Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20181228130446.22141-1-jani.nikula@intel.com

drm: document drm_auth.c

2016-06-21T20:10:55Z

Also extract drm_auth.h for nicer grouping. v2: Nuke the other comments since they don't really explain a lot, and within the drm core we generally only document functions exported to drivers: The main audience for these docs are driver writers. v3: Limit the exposure of drm_master internals by only including drm_auth.h where it is neede (Chris). v4: Spelling polish (Emil).
