drm: drop use of drmP.h in drm/*

2019-05-27T16:07:03Z

The use of the drmP.h header file is deprecated. Remove use from all files in drm/* so people do not look there and follow a bad example. Build tested allyesconfig,allmodconfig on x86, arm etc. Including alpha that is as always more challenging than the rest.

Pull drm updates from Dave Airlie: "This has two exciting community drivers for ARM Mali accelerators. Since ARM has never been open source friendly on the GPU side of the house, the community has had to create open source drivers for the Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx series. Well done to all involved and hopefully this will help ARM head in the right direction. There is also now the ability if you don't have any of the legacy drivers enabled (pre-KMS) to remove all the pre-KMS support code from the core drm, this saves 10% or so in codesize on my machine. i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo moves out of staging. There are also some rcar-du patches which crossover with media tree but all should be acked by Mauro.

drm: introduce a capability flag for syncobj timeline support

2019-05-02T02:36:47Z

Unfortunately userspace users of this API cannot be publicly disclosed yet. This commit effectively disables timeline syncobj ioctls for all drivers. Each driver wishing to support this feature will need to expose DRIVER_SYNCOBJ_TIMELINE. v2: Add uAPI capability check (Christian) Signed-off-by: Lionel Landwerlin Reviewed-by: Christian König (v1) Cc: Dave Airlie Cc: Daniel Vetter Cc: Christian König Cc: Chunming Zhou Reviewed-by: Dave Airlie Reviewed-by: Chunming Zhou Signed-off-by: Dave Airlie Link: https://patchwork.freedesktop.org/patch/msgid/20190416125750.31370-1-lionel.g.landwerlin@intel.com

drm: report consistent errors when checking syncobj capibility

We've been somewhat inconsistent when adding the new ioctl and returned ENODEV instead of EOPNOTSUPPORTED upon failing the syncobj capibility.
