This series aims to improve GPU-side performance by avoiding VK_IMAGE_LAYOUT_GENERAL for textures that are used as render target and shader resource view. To do so, we have to transition them between VK_IMAGE_LAYOUT_COLOR_ATTACHMENT_OPTIMAL and VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL depending on use (and likewise for depth stencils).
It improves performance of Rocket League from 80 fps to 100 fps in a GPU limited configuration on my Radeon Polaris GPU.
This MR is marked as draft for now because I am not convinced by patch 3 yet. For actual submission I think I'll create separate MRs for patches 1-3 and 4-8.
Patch 2 introduces a validation layer error in the d3d11 tests that gets fixed in patch 3. No new test failures are introduced, although none of the existing ones are fixed either.
-- v3: wined3d: Fall back to general layout if necessary. wined3d: Avoid VK_IMAGE_LAYOUT_GENERAL. wined3d: Sync depth stencils to both early and late depth test.
From: Stefan Dösinger stefan@codeweavers.com
We don't know which test the next draw will use when we place the barrier. We may be able to figure this out, but it is not trivial.
This avoids a read-after-write hazard after the next patch. The layout transition from shader-read-only to depth stencil needs to be finished before the early depth test in a follow-up draw if this draw uses early depth. --- dlls/wined3d/resource.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)

This improves GPU-side performance considerably by allowing the driver to keep lossless texture compression enabled for textures that are used as both render taget / depth stencil and shader resource.

I am not entirely happy with how default_image_info.imageLayout is handled. wined3d_texture_vk_get_default_image_info is called by wined3d_rendertarget_view_vk_get_image_view, although only the image view is taken, and not the entire descriptor. UAVs work because the BIND_UAV flag forces the texture to use VK_IMAGE_LAYOUT_GENERAL.
I contemplated making wined3d_texture_vk_get_default_image_info return only the view handle, and not the entire image info, but then we'd need extra storage to store the VkDescriptorImageInfo for each VkWriteDescriptorSet entry. I am not convinced this is better. One possibility is doing away with the default view entirely. --- dlls/wined3d/texture.c | 93 +++++++++++++++++++++++++++++++----------- dlls/wined3d/view.c | 5 ++- 2 files changed, 73 insertions(+), 25 deletions(-)

If a texture is used as shader resource and DS/RT at the same time, including cases where a different subresource is bound to each.
In theory this could be handled better, but would require per-subresource layout tracking.

It might make sense to merge this into the previous patch. Without it, we get a validation error in test_sample_attached_rtv. I feel it is easier to review them separately and we have plenty of pre-existing test and validation errors with the vulkan backend. --- dlls/wined3d/context_vk.c | 22 +++++++++++++++++++++- dlls/wined3d/texture.c | 29 +++++++++++++++++++++++++++++ dlls/wined3d/view.c | 8 +++++++- dlls/wined3d/wined3d_private.h | 6 +++++- 4 files changed, 62 insertions(+), 3 deletions(-)

I've approved this because I don't want to hold this up forever, and the ugly parts are well-commented, but yeah, I'm not happy with this either. Possibly we should just introduce a separate function to retrieve the image view. Alternatively, I don't know if we need to get rid of the default view (on the grounds that we shouldn't unnecessarily create Vulkan view objects?) but we could get rid of the default image info.
but we could get rid of the default image info.
That was my first thought as well, but we need to store an image info struct somewhere. VkWriteDescriptorSet takes a pointer to a VkDescriptorImageInfo, and that struct instance needs to live somewhere. Right now it either lives in the view or texture.
Yes, this can be handled e.g. by putting an extra dynamic array in wined3d_context_vk or modifying wined3d_shader_descriptor_writes_vk, but neither of those struck me as particularly beautiful.

Well, it can always live in the view, can't it? Or am I missing something?

Hmm right. It would live in every view that uses the default image view, but we should have space for it already.
It'll require some modifications to the code paths that fetch the VkDescriptorImageInfo, but by my quick estimate they'd change for the better.
