drm: Add DRM_MODE_PAGE_FLIP_TARGET_ABSOLUTE/RELATIVE flags v2

2016-08-10T18:28:09+00:00

These flags allow userspace to explicitly specify the target vertical
blank period when a flip should take effect.

v2:
* Add new struct drm_mode_crtc_page_flip_target instead of modifying
  struct drm_mode_crtc_page_flip, to make sure all existing userspace
  code keeps compiling (Daniel Vetter)

drm: Make uapi headers C89 pendantic compliant

2016-03-31T05:57:50+00:00

This ports the below libdrm commit to the kernel

commit 0f4452bb51306024fbf4cbf77d8baab20cefba67
Author: Daniel Kurtz 
Date:   Mon Aug 26 23:39:16 2013 +0800

    libdrm: Make some drm headers compatible with gcc -std=c89 -pedantic

    The following minor changes were needed to these headers:
     * Convert // comments to /* */
     * No , after final member of enum

    With these changes, these header files can be included by a program that
    is built with gcc options:
      -std=c89 -Werror -pedantic

drm: Untangle KERNEL guards

2016-03-30T19:09:33+00:00

make headers_install can't handle fancy conditions, so let's simplify
things for it a bit.

drm: align #include directives with libdrm in uapi headers

2016-03-30T19:08:09+00:00

We can't use  because that upsets the serach paths in libdrm.
Also, drop the circular inclusion in drm_mode.h.

v2: Actually change the right headers.

v3: Drop the #include removal per Emil's request.

drm: Make drm.h uapi header safe for C++

2016-03-30T19:07:45+00:00

virtual is a protected keyword in C++ and can't be used at all. Ugh.

This aligns the kernel versions of the drm headers with the ones in
libdrm.

v2: Also annote with __user, as request by Emil&Ilia.

drm: prime: Honour O_RDWR during prime-handle-to-fd

2016-02-09T08:25:12+00:00

Currently DRM_IOCTL_PRIME_HANDLE_TO_FD rejects all flags except
(DRM|O)_CLOEXEC making it difficult (maybe impossible) for userspace
to mmap() the resulting dma-buf even when this is supported by the
DRM driver.

It is trivial to relax the restriction and permit read/write access.
This is safe because the flags are seldom touched by drm; mostly they
are passed verbatim to dma_buf calls.

v3 (Tiago): removed unused flags variable from drm_prime_handle_to_fd_ioctl.

drm/mode: Add user blob-creation ioctl

2015-05-22T14:18:28+00:00

Add an ioctl which allows users to create blob properties from supplied
data. Currently this only supports modes, creating a drm_display_mode from
the userspace drm_mode_modeinfo.

v2: Removed size/type checks.
    Rebased on new patches to allow error propagation from create_blob,
    as well as avoiding double-allocation.

drm: add support for tiled/compressed/etc modifier in addfb2

2015-02-13T22:28:12+00:00

In DRM/KMS we are lacking a good way to deal with tiled/compressed
formats.  Especially in the case of dmabuf/prime buffer sharing, where
we cannot always rely on under-the-hood flags passed to driver specific
gem-create ioctl to pass around these extra flags.

The proposal is to add a per-plane format modifier.  This allows to, if
necessary, use different tiling patters for sub-sampled planes, etc.
The format modifiers are added at the end of the ioctl struct, so for
legacy userspace it will be zero padded.

v1: original
v1.5: increase modifier to 64b

v2: Incorporate review comments from the big thread, plus a few more.

- Add a getcap so that userspace doesn't have to jump through hoops.
- Allow modifiers only when a flag is set. That way drivers know when
  they're dealing with old userspace and need to fish out e.g. tiling
  from other information.
- After rolling out checks for ->modifier to all drivers I've decided
  that this is way too fragile and needs an explicit opt-in flag. So
  do that instead.
- Add a define (just for documentation really) for the "NONE"
  modifier. Imo we don't need to add mask #defines since drivers
  really should only do exact matches against values defined with
  fourcc_mod_code.
- Drop the Samsung tiling modifier on Rob's request since he's not yet
  sure whether that one is accurate.

v3:
- Also add a new ->modifier[] array to struct drm_framebuffer and fill
  it in drm_helper_mode_fill_fb_struct. Requested by Tvrkto Uruslin.
- Remove TODO in comment and add code comment that modifiers should be
  properly documented, requested by Rob.
