[PATCH] libdrm: vblank wait on crtc > 1
Hi Alex,
Below is a patch against the master branch of libdrm that adds support
for waits for vblank events on CRTCs that are greater than 1 (and thus
cannot be represented using current primary/secondary flags interface).
The patch adds a new DRM_CAP so that the application can check whether the
new vblank interface is supported and also adds the new DRM_VBLANK mask
and shift value so that the application can construct vblank_wait ioctls
that refer to crtc > 1
