drm/legacy: Fix type for drm_local_map.offset

2020-04-09T07:06:45+00:00

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

2020-02-04T23:57:26+00:00

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

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()

2019-01-02T09:37:11+00:00

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

2016-06-21T20:10:55+00:00

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).

drm: Hide master MAP cleanup in drm_bufs.c

2016-04-27T08:14:17+00:00

And again make sure it's a no-op for modern drivers. Another case of dev->struct_mutex gone for modern drivers! Note that the entirety of the legacy addmap interface is now protected by DRIVER_MODESET. Note that just auditing kernel code is not enough, since userspace loves to set up legacy maps on it's own for various things - with ums userspace and kernel space share control over resources. v2: Also add a DRIVER_* check like for all other maps functions to really short-circuit the code. And give drm_legacy_rmmap used by the dev unregister code the same treatment. v3: - remove redundant return; (Alex, Chris) - don't special case nouveau with DRIVER_KMS_LEGACY_CONTEXT. v4: Again special case nouveau. The problem is not directly in the ddx, but that it calls dri1 functions from the X server. And those do call drmAddMap.

drm: move drm_mmap to

2014-09-24T01:43:07+00:00

Now that we've removed the copypasted users in gem/ttm we can relegate the legacy buffer mapping support to where it belongs. Also give it the proper drm_legacy_ prefix. While at it statify drm_mmap_locked, somehow I've missed that in my previous header rework. Signed-off-by: Daniel Vetter Reviewed-by: David Herrmann Acked-by: Alex Deucher Signed-off-by: Dave Airlie
