Rather than waiting on the first batch after the last swapbuffers to be
retired, call into the kernel to wait upon the retirement of any request
less than 20ms old. This has the twofold advantage of (a) not blocking
any other clients from utilizing the device whilst we wait and (b) we
attain higher throughput without overloading the system.

As we will flush when reading the return values of the blit, we can forgo
the earlier flush.

If the next vertex arrays are a (discontiguous) continuation of the
current arrays, such that the new vertices are simply offset from the
start of the current vertex buffer definitions we can reuse those
defintions and avoid the overhead of relocations and invalidations.

Use a temporary glarray variable to replace the numerous input->glarray.

Using a temporary buffer for large discontiguous uploads into the common
buffer and a single buffered upload is faster than performing the
discontiguous copies through a mapping into the GTT.

Upload the non-vbo arrays into a single interleaved buffer object, and
so need to just emit a single vertex buffer relocation.

If the user passed in several arrays interleaved in the same vbo, only
emit a single vertex buffer and relocation.

Track reuse of the vertex buffer objects and so minimise the number of
vertex buffers used by the hardware (and their relocations).

As we now pack the indices into a common upload buffer, we can reuse a
single CMD_INDEX_BUFFER packet and translate each invocation with a
start vertex offset.

Move the tracking of the last emitted instructions into the core
batchbuffer routines and take advantage of the shadow batch copy to
avoid extra memory allocations and copies.

It's faster. Not only is the memcpy more efficiently performed in the
kernel (making up for the system call overhead), but by not using mmap
we remove the greater overhead of tracking the vma of every batch.
And it means we can read back from the batch buffer without incurring
the cost of a uncached read through the GTT.

As we use state relocations and we know that all the state belongs to
the same bo, we can drop the multiple references to the same bo.

As we write directly into the batch in system memory, we do not need to
write first to the stack (as was to avoid read back through the GTT)

In preparation for a greater change, use the color_calc_state_bo already

Rather than performing lots of little writes to update the common bo
upon each update, write those into a static buffer and flush that when
full (or at the end of the batch). Doing so gives a dramatic performance
improvement over and above using mmaped access.

Rather than performing a blit to completely overwrite a busy bo, simply
discard it and create a new one with the fresh data.

Reuse the new common upload buffer for uploading temporary indices and

Dynamic arrays have the tendency to be small and so allocating a bo for
each one is overkill and we can exploit many efficiency gains by packing
them together.

Dynamic draw buffers are used by clients for temporary arrays and for
uploading normal vertex arrays. By keeping the data in memory, we can
avoid reusing active buffer objects and reallocate them as they are
changed. This is important for Sandybridge which can not issue blits
within a batch and so ends up flushing the batch upon every update, that
is each batch only contains a single draw operation (if using dynamic
arrays or regular arrays from system memory).

Following a GPU hang, or other error, the render target is not likely to
have an allocated BO and so we must fallback to avoid using it.

Atomics aren't sufficient here.

radeon_bo_unref may destroy the buffer, so call it after p_atomic_dec, not before.

This behavior was last when moving the transfers to the contexts.
This fixes several piglit failures, which were reading the color renderbuffer
before the draw operations were emitted.

The dst reg must be a temporary, and not be the same as src0 or src2.

Several opcodes require scalar swizzle, and this requirement was
being was not being observed when creating temporaries for other reasons.

This was getting hard to maintain and didn't really bring any real benefits.
Instead, validate buffers when the vertex array state is dirty.

This is a temporary workaround. It fixes sauerbrauten with shaders enabled.
I guess we might be changing vertex attribs somewhere and not updating
the appropriate dirty flags, therefore we can't rely on them for now.
Or maybe we need to make this state dependent on some other flags too.
