Rename all anv_*_view variables to follow this convention:
- sview -> anv_surface_view
- bview -> anv_buffer_view
- iview -> anv_image_view
- aview -> anv_attachment_view
- cview -> anv_color_attachment_view
- ds_view -> anv_depth_stencil_attachment_view
This clarifies existing code. And it will reduce noise in the upcoming
commits that merge VkAttachmentView into VkImageView.
For a given struct anv_descriptor, all members are NULL (in which case
the descriptor is empty) or exactly one member is non-NULL.
To make struct anv_descriptor better reflect its set of valid states,
convert the struct into a tagged union.
Previously, we simply had a big blob of stuff for "driver constants". Now,
we have a very specific data structure that contains the driver constants
that we care about.
With all the previous commits in place, we can now drop in support for
multiple platforms. First up is gen7 (Ivybridge).

We need this for generating surface state on the fly for dynamic buffer
views.

We're going to have to do this differently for earlier gens, so lets do
it in place only.

We'll organize gen specific code in three files per gen: pipeline,
cmd_buffer and state, eg:
gen8_cmd_buffer.c
gen8_pipeline.c
gen8_state.c
where gen8_cmd_buffer.c holds all vkCmd* entry points, gne8_pipeline.c
all gen specific code related to pipeline building and remaining state
code (sampler, surface state, dynamic state) in gen8_state.c.

Change type of anv_surface_view::format from VkFormat to const struct
anv_format*. This reduces the number of lookups in the VkFormat ->
anv_format table.
This moves the translation of VkFormat to anv_format from
anv_fill_buffer_surface_state() to its caller.
A prep commit to reduce more VkFormat -> anv_format translations.
Previously, the command buffer implementation was split between
anv_cmd_buffer.c and anv_cmd_emit.c. However, this naming convention was
confusing because none of the Vulkan entrypoints for anv_cmd_buffer were
actually in anv_cmd_buffer.c. This changes it so that anv_cmd_buffer.c is
what you think it is and the internals are in anv_batch_chain.c.
This is more generic and doesn't imply that it emits MI_BATCH_BUFFER_END.
While we're at it, we'll move NOOP adding from bo_finish to
end_batch_buffer.
Instead of walking the list of batch and surface buffers, we simply keep
track of all known batch and surface buffers as we build the command
buffer. Then we use this new list to construct the validate list.
The algorighm we used previously required us to call add_bo in a particular
order in order to guarantee that we get the initial batch buffer as the
last element in the validate list. The new algorighm does a recursive walk
over the buffers and then re-orders the list. This should be much more
robust as we start to add circular dependancies in the relocations.
Before, we were doing this thing where we had one big relocation list for
the whole command buffer and each subbuffer took a chunk out of it. Now,
we store the actual relocation list in the anv_batch_bo. This comes at the
cost of more small allocations but makes a lot of things simpler.
Previously anv_batch.relocs was an actual relocation list. However, this
is limiting if the implementation of the batch wants to change the
relocation list as the batch progresses.
This used to happen magically in cmd_buffer_new_surface_state_bo. However,
according to Ken, STATE_BASE_ADDRESS is very gen-specific so we really
shouldn't have it in the generic data-structure code.
Jason started the task by creating anv_cmd_buffer.c and anv_cmd_emit.c.
This patch finishes the task by renaming all other files except
gen*_pack.h and glsl_scraper.py.
