[PATCH] Add drm ioctl DRM_IOCTL_MODE_GETFB2 & associated helpers.
...eOS gfx team. I am currently
working on display testing and reporting. An important part of this is
our screen capture tool, which works by querying drm for crtcs, planes, and
fbs. Unfortunately, there is only limited information available via
drmModeGetFB(), which often wrong information when drmModeAddFB2() was used
to create the fbs. For example, if the pixel format is NV12 or YUV420,
the fb returned knows nothing about the additional buffer planes required
by these formats. Ideally, we would like a function (e.g. drmModeGetFB2)
to return information symmetric with drmModeAddFB2 including the p...

[PATCH] Add drm ioctl DRM_IOCTL_MODE_GETFB2 & associated helpers.
New getfb2 functionality uses drm_mode_fb_cmd2 struct to be symmetric
with addfb2. Also modifies *_fb_create_handle() calls to accept a
format_plane_index so that handles for each plane can be generated.
Previously, many *_fb_create_handle() calls simply defaulted to plane 0 only.
