2019-05-27drm: make drm_legacy.h self-containedSam Ravnborg1-0/+4
Do not require users of drm_legacy.h to include other files just to let it build Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Daniel Vetter <daniel@ffwll.ch> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <maxime.ripard@bootlin.com> Cc: Sean Paul <sean@poorly.run> Cc: David Airlie <airlied@linux.ie> Link: https://patchwork.freedesktop.org/patch/msgid/20190526173535.32701-6-sam@ravnborg.org
2019-05-09drm: Some ocd in drm_file.cDaniel Vetter1-0/+2
Move the open helper around to avoid the forward decl, and give drm_setup a drm_legacy_ prefix since it's all legacy stuff in there. v2: Move drm_legacy_setup into drm_legacy_misc.c (Chris). The counterpart in the form of drm_legacy_dev_reinit is there already too, plus it fits perfectly into Dave's work of making DRIVER_LEGACY code compile-time optional.

2019-04-24drm/legacy: remove some legacy lock struct membersDave Airlie1-0/+6
This removes these unless legacy is enabled. The lock count init is unneeded anyways since it's kzalloc. Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>
2019-04-24drm/legacy: place all drm legacy members under DRM_LEGACY.Dave Airlie1-0/+9
This places a bunch of the legacy members of drm_device into only being there when legacy is enabled. Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>
2019-04-24drm: allow removal of legacy codepaths (v4.1)Dave Airlie1-2/+51
If you don't want the legacy drivers, then lets get rid of all the legacy codepaths from the core module.

2019-04-24drm/legacy: move init/destroy of struct members into legacy fileDave Airlie1-0/+3
This introduces drm_legacy_misc.c as a place for some misc legacy code, eventually I want to give the option to remove this from the build. Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>

2017-07-04switch compat_drm_mapbufs() to drm_ioctl_kernel()Al Viro1-0/+4

2017-01-06drm: compile drm_vm.c only when neededBenjamin Gaignard1-0/+7
drm_vm.c functions are only need for DRM_LEGACY and DRM_NOUVEAU. Use a new DRM_VM to define when drm_vm.c in needed. stub drm_legacy_vma_flush() to avoid compilation issues version 4: - a "config DRM_VM" in Kconfig Signed-off-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> [danvet: Fix conflict.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2016-06-16drm: Hide hw.lock cleanup in filp->release betterDaniel Vetter1-6/+2
A few things: - Rename the cleanup function from drm_master_release to drm_legacy_lock_release. It doesn't relase any master stuff, but just the legacy hw lock. - Hide it in drm_lock.c, which allows us to make a few more functions static in there. To avoid forward decl we need to shuffle the code a bit though. - Push the check for ->master into the function itself. - Only call this for !DRIVER_MODESET. End result: Another place that takes struct_mutex gone for good for modern drivers. v2: Remove leftover comment.

2014-09-12drm: Create drm legacy driver headerDaniel Vetter1-0/+1

2014-09-10drm: move drm-lock API to drm_legacy.hDavid Herrmann1-0/+9

2014-09-10drm: move AGP definitions harderDavid Herrmann1-0/+15
Move drm_agp_head to drm_agpsupport.h and drm_agp_mem into drm_legacy.h. Unfortunately, drivers still heavily access drm_agp_head so we cannot move it to drm_legacy.h. However, at least it's no longer visible in drmP.h now (it's directly included from it, though).
