Now that we have anv_nir_apply_pipeline_layout, we can hand the backend
compiler intrinsics and texture instructions that use a flat buffer index
just like it wants. There's no longer any reason for any of these hacks.
This patch reworks a bunch of stuff in the way we do descriptor set
layouts. Our previous approach had a couple of problems. First, it was
based on a misunderstanding of arrays in descriptor sets. Second, it
didn't properly handle descriptor sets where some bindings were missing
stages. The new apporach should be correct and also makes some operations,
particularly those on the hot-path, a bit easier.
We use the descriptor set layout for four things:
1) To determine the map from bindings to the actual flattened descriptor
set in vkUpdateDescriptorSets().
2) To determine the descriptor <-> binding table entry mapping to use in
anv_cmd_buffer_flush_descriptor_sets().
3) To determine the mappings of dynamic indices.
4) To determine the (set, binding, array index) -> binding table entry
mapping inside of shaders.
The new approach is directly taylored towards these operations.
The surface_format_info struct changed in mesa but the copied-and-pasted
version didn't get updated on the last mesa master merge. This both fixes
the bug and should prevent this in the future.
This was a remnant of the object tagging implementation we had at one
point. We haven't used it for a long time so there's no good reason to
keep it around.
Version 0.170.2 removes most of the error enums. In many cases, I had to
replace an error with a less accurate (or even incorrect) one.
In other cases, the error path is replaced with an assertion.
In C, functions with no arguments require a void argument.
build_nir_clear_fragment_shader() lacked that.
Fixes:
anv_meta.c:70:1: warning: function declaration isn't a prototype
[-Wstrict-prototypes]
If anv_image_get_surface_for_aspect_mask() is given a combined
depthstencil aspect mask, and the image has a stencil surface but no
depth surface, then return the stencil surface.
Hacks on hacks.
Eliminates lots of warnings due to anv_meta.c's inclusion of nir.h.
I like the extra warnings, and they should probably get fixed. However,
git-grep reveals that no other Mesa directory uses -Wextra. Building
Vulkan produces a lot of compiler warnings from core Mesa headers that
no other Mesa developer sees, and hence no other Mesa developer will
fix.
This prepares for merging VkAttachmentView into VkImageView. The two
surface states are:
anv_image_view::color_rt_surface_state:
RENDER_SURFACE_STATE when using image as a color render target.
anv_image_view::nonrt_surface_state;
RENDER_SURFACE_STATE when using image as a non render target.
No Crucible regressions.
In make_image_for_buffer(), use VK_IMAGE_USAGE_SAMPLED_BIT when
transferring from the buffer and use VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT
when transferring to the buffer.
