Previously, anv_image_view had a anv_format pointer that we used for
everything. This commit replaces that pointer with a VkFormat enum copied
from the API and an isl_format. In order to implement RGB formats, we have
to use a different isl_format for the actual surface state than the obvious
one from the VkFormat. Separating the two helps us keep things streight.
This made for an unfortunately large amount of work since we were using it
fairly heavily internally. However, gl_shader_stage does basically the
same things, so it's not too bad.
This packet is a different size on gen8 and we hit an assertion when we
try to merge a gen9 size dword array from the pipeline with the gen8
sized array we create from dynamic state.
Use a static assert in the merge macro and fix this issue by using different
wm_depth_stencil arrays on gen8 and gen9.
This file contains code that can be shared across gens modulo recompiling.
In particular, we can share STATE_BASE_ADDRESS setup and handling of the
vkPipelineBarrier call. Not sharing STATE_BASE_ADDRESS setup has already
been a source of bugs and the gen7 and gen8 implementations of
PipelineBarrier were line-for-line identical.
Incidentally, this should fix MOCS settings for dynamic and surface state
on Haswell.
Previously, we were including gen7_pack.h, gen75_pack.h, and gen8_pack.h
in anv_private.h. As we add more gens, this is going to become untenable.
This commit moves things around so that we only use the pack headers when
and if we need them.
Prefix all anv_cmd_state dirty bit tokens with ANV_CMD_DIRTY. For
example:
old -> new
ANV_DYNAMIC_VIEWPORT_DIRTY -> ANV_CMD_DIRTY_DYNAMIC_VIEWPORT
ANV_CMD_BUFFER_PIPELINE_DIRTY -> ANV_CMD_DIRTY_PIPELINE
Change type of anv_cmd_state::dirty and ::compute_dirty from uint32_t to
the self-documenting type anv_cmd_dirty_mask_t.
Remove anv_color_attachment_view and anv_depth_stencil_view, merging
them into anv_attachment_view. This prepares for merging
VkAttachmentView into VkImageView.
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.
Stencil buffers have strange pitch. The PRM says:
The pitch must be set to 2x the value computed based on width,
as the stencil buffer is stored with two rows interleaved.
In anv_depth_stencil_view, replace the members
bo
depth_offset
depth_stride
depth_format
depth_qpitch
stencil_offset
stencil_stride
stencil_qpitch
with the single member
const struct anv_image *image
The removed members duplicated data in anv_image::depth_surface and
anv_image::stencil_surface.
The format of the view itself and of the view's image may differ.
Moreover, if the view's format has no depth aspect but the image's
format does, we must not program the depth buffer. Ditto for stencil.
This commit moves all occurances of gen8 specific state into a gen8
substruct. This clearly identifies the state as gen8 specific and
prepares for adding gen7 state structs. In the process we also rename
the field names to exactly match the command or state packet name,
without the 3DSTATE prefix, eg:
3DSTATE_VF -> gen8.vf
3DSTATE_WM_DEPTH_STENCIL -> gen8.wm_depth_stencil

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.
