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: Forbid legacy MAP functions for DRIVER_MODESET

2016-04-27T08:05:54Z

Like in commit 0e975980d435d58df2d430d688b8c18778b42218 Author: Peter Antoine Date: Tue Jun 23 08:18:49 2015 +0100 drm: Turn off Legacy Context Functions we need to again make an exception for nouveau, but everyone else really doesn't need this. Dave Airlie dug out again why we need this: The problem is the legacy dri1 open function the nouveau ddx called, and the problematic code is actually in the X server itself.

drm: Move drm_getmap into drm_bufs.c and give it a legacy prefix

2016-04-27T06:42:48Z

It belongs right next to the addmap and rmmap functions really. And for OCD consistency name it drm_legacy_getmap_ioctl.

drm: Remove __OS_HAS_AGP

2015-09-30T08:44:48Z

We already express the drm/agp depencies correctly in Kconfig, so we can rip this remnant from the shared drm core days. Aside: Pretty much all the #ifdefs in radeon/nouveau could be killed if ttm would provide dummy functions. I'm not going to volunteer for that though. v2: Use IS_ENABLED(CONFIG_AGP) as suggested by Ville v3: Polish from Ville's review.

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: Move dma functions into drm_legacy.h

2014-09-12T09:08:53Z

Also drop the unneeded EXPORT_SYMBOL and sprinkle drm_legacy_ prefixes where missing. v2: Drop the confusing _core_ and drop extern, both suggested by David. Cc: David Herrmann Signed-off-by: Daniel Vetter
