We were calculating the total height of 2D surfaces by multiplying the
row pitch by the number of slices. This means that we actually request
slightly more space than actually needed since the padding on the last
slice is unnecessary. For tiled surfaces this is not likely to make a
difference. For linear surfaces, on the other hand, this means we may
require additional memory. In particular, this makes the i965 driver
reject EGL imports of buffers which do not have this extra padding.

The docs contain a bunch of commentary about the need to pad various
surfaces out to multiples of something or other. However, all of those
requirements are about avoiding GTT errors due to missing pages when the
data port or sampler accesses slightly out-of-bounds. However, because
the kernel already fills all the empty space in our GTT with the scratch
page, we never have to worry about faulting due to OOB reads. There are
two caveats to this:
1) There is some potential for issues with caches here if extra data
ends up in a cache we don't expect due to OOB reads. However,
because we always trash the entire cache whenever we need to move
anything between cache domains, this shouldn't be an issue.
2) There is a potential issue if a surface gets placed at the very top
of the GTT by the kernel. In this case, the hardware could
potentially end up trying to read past the top of the GTT. If it
nicely wraps around at the 48-bit (or 32-bit) boundary, then this
shouldn't be an issue thanks to the scratch page. If it doesn't,
then we need to come up with something to handle it.
Up until some of the GL move to ISL, having the padding code in there
just caused us to harmlessly use a bit more memory in Vulkan. However,
now that we're using ISL sizes to validate external dma-buf images,
these padding requirements are causing us to reject otherwise valid
images due to the size of the BO being too small.

This patch adds support for large shaders on GC3000. For example the "terrain"
glmark benchmark with a large fragment shader will work after this.
If the GPU supports ICACHE, shaders larger than the available state area will
be uploaded to a bo of their own and instructed to be loaded from memory on
demand. Small shaders will be uploaded in the usual way. This mimics the
behavior of the blob.
On GPUs that don't support ICACHE, this patch should make no difference.

GC3000 has changed from a separate store for VS and PS uniforms

however this does not work correctly together with ICACHE.
This patch adds explicit support, although in the simplest way possible:
the PS/VS uniforms split is still fixed and hardcoded. It should

The kernel only cares about whether the object is to be written to or
not, only reduces (reloc.read_domains, reloc.write_domain) down to just
!!reloc.write_domain. When we use NO_RELOC, the kernel doesn't even read
those relocs and instead userspace has to pass that information in the
execobject.flags. We can simplify our reloc api by also removing the
unused read/write domains and only pass the resultant flags.
The caveat to the above are when we need to make the kernel aware that
certain objects need to take into account different work arounds.
Previously, this was done using the magic (INSTRUCTION, INSTRUCTION)
reloc domains. NO_RELOC requires this to be passed in the execobject
flags as well, and now we push that up the callstack.
The API is more compact, more expressive of what happens underneath, but
unfortunately requires more knowledge of the system at the point of use.
Conversely it also means that knowledge is specific and not generally
applied and so not overused.

Based on a patch by Chris Wilson (who also wrote this commit message).
Passing the index of the target buffer via the reloc.target_handle is
marginally more efficient for the kernel (it can avoid some allocations,
and can use a direct lookup rather than a hash or search). It is also
useful for ourselves as we can use the index into our exec_bos for other
tasks.
