connector_id in the uapi actually means drm_connector->base.id, which
is something entirely different. And ->index is also consistent with
plane/encoder/CRTCS and the various drm_*_index() functions.
While at it also improve/align the kerneldoc comment.
v2: Mention where those ids are from ...
v3: Add -ing to supporting and try to not break the world.

The drm_irq docs want one function from drmP.h, but that one is a
serious mess. Extract it, and while at it improve the docs a bit.
There's a bit a header loop issue since core data structures like
drm_device and drm_driver aren't in their own headers yet, which means
the drm_irq.h include in drmP.h needs to be in just the right spot :(
Also noticed that drm_vblank_crtc->last_wait is entirely unused,
remove it.

This has now been removed from all drivers as it is performed centrally
as a part of device unregistration for modesetting drivers. With the last
user gone, we can unexport it from the DRM module. That requires us to
move the code slightly to avoid the need for a forward declaration.

vGEM buffers are useful for passing data between software clients and
hardware renders. By allowing the user to create and attach fences to
the exported vGEM buffers (on the dma-buf), the user can implement a
deferred renderer and queue hardware operations like flipping and then
signal the buffer readiness (i.e. this allows the user to schedule
operations out-of-order, but have them complete in-order).
This also makes it much easier to write tightly controlled testcases for
dma-buf fencing and signaling between hardware drivers.
v2: Don't pretend the fences exist in an ordered timeline, but allocate
a separate fence-context for each fence so that the fences are
unordered.
v3: Make the debug output more interesting, and show the signaled status.
v4: Automatically signal the fence to prevent userspace from
indefinitely hanging drivers.

Userspace needs to know if it can create shaders that do branching.
Otherwise, for backwards compatibility with old kernels it needs to
lower if statements to conditional assignments.
Signed-off-by: Eric Anholt <eric@anholt.net>
We're already checking that branch instructions are between the start
of the shader and the proper PROG_END sequence. The other thing we
need to make branching safe is to verify that the shader doesn't read
past the end of the uniforms stream.
To do that, we require that at any basic block reading uniforms have
the following instructions:
load_imm temp, <next offset within uniform stream>
add unif_addr, temp, unif
The instructions are generated by userspace, and the kernel verifies
that the load_imm is of the expected offset, and that the add adds it
to a uniform. We track which uniform in the stream that is, and at
draw call time fix up the uniform stream to have the address of the
