    vc4: Flip which primitives are considered front-facing.
    
    This mostly fixes glxgears rendering.

    vc4: Don't forget to set the depth clear value in the packet.
    
    This gets glxgears partially rendering again.

    vc4: Add support for gl_FragCoord.
    
    This isn't passing all tests (glsl-fs-fragcoord-zw-ortho, for example),
    but it does get a bunch more tests passing.
    
    v2: Rebase on helpers change.

    vc4: Refactor shader input setup again.
    
    This makes some space for handling special inputs like fragcoords.

    vc4: Clean up the tile alloc buffer size.
    
    This prevents some simulator assertion failures, but it does mean (since
    I've dropped the "* 16" padding) that on real hardware you need a kernel
    that does overflow memory management (currently, "drm/vc4: Add support for
    binner overflow memory allocation." in my kernel tree).

    vc4: Clarify some values implicitly chosen for binning config.
    
    These #defines are 0, but it should help make math above make more sense.

    vc4: Improve simulator memory allocation.
    
    This should reduce a bunch of spurious failures in sim.

    vc4: Stash some debug code for looking at what BOs are at what hindex.
    
    When you're debugging validation, it's nice to know what the BOs are for.

    vc4: Use GEM under simulation even for non-winsys BOs.
    
    In addition to reducing sim-specific code, it also avoids our local handle
    allocation conflicting with the host GEM's handle numbering, which was
    causing vc4_gem_hindex() to not distinguish between winsys BOs and the
    same-numbered non-winsys bo.

    vc4: Don't forget to unmap the GEM BO when freeing.
    
    Otherwise it'll stick around forever.

Date:   Sat Aug 2 21:28:34 2014 -0700

    vc4: Add validation of raster-format textures.
    
    ... and reject everything else, for now.
    
    v2: Rebase on v2 of the rendering config validation change.

Date:   Sat Aug 2 21:23:20 2014 -0700

    vc4: Drop VC4_PACKET_PRIMITIVE_LIST_FORMAT.
    
    It's not relevant to our command streams any more.
    
    v2: Fix indentation and a typo in the comment.

    vc4: Fix the shader record size for extended strides.
    
    It turns out they aren't packed when attributes are missing, according to
    both docs and simulation.

Date:   Fri Aug 1 20:23:31 2014 -0700

    vc4: Validate that the same BO doesn't get reused for different purposes.
    
    We don't care if things like vertex data get smashed by render target
    data, but we do need to make sure that shader code doesn't get rendered
    to.
    
    v2: Fix overflowing read of gl_relocs[] that incorrect flagged of some
        VBOs as shader code.

    vc4: Rename GEM_HANDLES to be in a namespace.
    
    It's not a real VC4 hardware packet, but I've put in a comment to explain
    it.

    vc4: Clean up TMU write validation.
    
    The comment conflicted with the support in the code, so I moved the TMU
    write validation to where the comment was, and dropped some dead arguments
    from the functions while changing their signatures.

    vc4: Add proper translation from Zc to Zs for vertex output.
    
    This fixes the remaining failure in depthfunc.

Date:   Fri Aug 1 13:32:49 2014 -0700

    vc4: Add support for depth clears and tests within a tile.
    
    This doesn't load/store the Z contents across submits yet.  It also
    disables early Z, since it's going to require tracking of Z functions
    across multiple state updates to track the early Z direction and whether
    it can be used.
    
    v2: Move the key setup to before the search for the key.

    vc4: Avoid flushing when mapping buffers that aren't in the batch.
    
    This should prevent a bunch of unnecessary flushes for things like
    updating immediate vertex data.

    vc4: Align following shader recs to 16 bytes.
    
    Otherwise, the low address bits will end up being interpreted as attribute
    counts.

    vc4: Keep a reference to BOs queued for rendering.
    
    Otherwise, once we're not flushing at the end of every draw, we'll free
    things like gallium resources, and free the backing GEM object, before
    we've flushed the rendering using it to the kernel.

    vc4: Compute the proper end address of the relocated command lists.
    
    render_cl_size/bin_cl_size includes relocations, while the hardware buffer
    doesn't.  If you don't emit a HALT packet, the command parser continues
    until the end register's value.  We can't allow executing unvalidated
    buffer contents (and it's actually harmful in the render lists Mesa is
    emitting, since VC4_PACKET_STORE_MS_TILE_BUFFER_AND_EOF doesn't trigger a
    halt).

    vc4: Walk tiles horizontally, then vertically.
    
    I was confused looking at my addresses in dumps because I was seeing the
    tile branch offsets jumping all over.

    vc4: Track clears veresus uncleared draws, and the clear color.
    
    This is a step toward queueing more than one draw per frame.
    
    Fixes piglit attribute0 test, since we get a working clear color now.

    We only want to set up render target config and clear colors once per
    frame.

    vc4: Rename fields in the kernel interface.
    
    I decided I didn't like "len" compared to "size", and I keep typing
    shader_rec instead of shader_record[s] elsewhere, so make it consistent.

    vc4: Rewrite the kernel ABI to support texture uniform relocation.
    
    This required building a shader parser that would walk the program to find
    where the texturing-related uniforms are in the uniforms stream.
    
    Note that as of this commit, a new kernel is required for rendering on
    actual VC4 hardware (currently that commit is named "drm/vc4: Introduce
    shader validation and better command stream validation.", but is likely to
    be squashed as part of an eventual merge of the kernel driver).

    vc4: Switch simulator to using kernel validator
    
    This ensures that when I'm using the simulator, I get a closer match to
    what behavior on real hardware will be.  It lets me rapidly iterate on the
    kernel validation code (which otherwise has a several-minute turnaround
    time), and helps catch buffer overflow bugs in the userspace driver
    faster.

    vc4: Add support for texturing (under simulation)
    
    Only rgba8888 works, and only a single texture unit, and it's only under
    simulation because I haven't built the kernel interface yet.
