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).

drm: Hide master MAP cleanup in drm_bufs.c

2016-04-27T08:14:17Z

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

2014-09-24T01:43:07Z

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

drm: Move LOCK_TEST_WITH_RETURN to

2014-09-12T13:28:13Z

Unfortunately we can't move struct drm_lock_data easily since it's embedded into struct drm_master. And figuring out where exactly this struct should be allocated isn't that simple ... Signed-off-by: Daniel Vetter

drm: Move legacy buffer structures to

2014-09-12T13:28:12Z

A few odd cases: - mgag200 someho had a totally unused drm_dma_handle_t. Remove it. - i915 still uses the legacy pci dma alloc api, so grows an include. Everything else fairly standard. v2: Include "drm_legacy.h" in drm.ko source files for consistency. Signed-off-by: Daniel Vetter

drm: Move drm_memory.c map support declarations to

2014-09-12T13:28:12Z

And replace the drm_core_ prefix with drm_legacy_ since really, this isn't core stuff. Also drop drm_core_dropmap since it's unused. v2: Fix up i810.ko fully which somehow slipped through. Signed-off-by: Daniel Vetter

drm: Move __drm_pci_free to drm_legacy.h

2014-09-12T09:08:56Z

Also sprinkle the customary legacy_ prefix. Unfortunately we can't move the other functions since i915 is still using them. Shame on me for that one :( v2: Fix patch subject as spotted by David Herrmann. Signed-off-by: Daniel Vetter

drm: Create drm legacy driver header

2014-09-12T09:08:55Z

And move a few legayc functions to start things over there. It compiles ... Inspired by a patch from Dave Airlie, but with a split between drm.ko private legacy functions and stuff used by drivers. Signed-off-by: Daniel Vetter
