For resizable BAR, we don't want to endlessly promote UPLOAD heaps to
BAR since VRAM is precious. The aim is to set a fixed budget where we
can keep allocating until full, at which point we fall back to plain HOST.
Signed-off-by: Hans-Kristian Arntzen <post@arntzen-software.no>
With BAR budgets, what will happen is that
- Small allocation is requested
- A new chunk is requested
- try_suballocate_memory will end up calling allocate_memory, which
allocates a fallback memory type
- Subsequent small allocators will always end up allocating a new
fallback memory block, never reusing existing blocks.
- System memory is rapidly exhausted once apps start hitting against
budget.
The fix is to add flags which explicitly do not attempt to fallback
allocate. This makes it possible to handle fallbacks at the appropriate
level in try_suballocate_memory instead.

There are titles clearing the same descriptors constantly.

Goal here is to avoid unnecessary image layout transitions when render
passes toggle depth-stencil PSO states. Since we cannot know which
states a resource is in, we have to be conservative, and assume that
shader reads *could* happen.
The best effort we can do is to detect when writes happen to a DSV
resource. In this scenario, we can deduce that the aspect cannot be
read, since DEPTH_WRITE | RESOURCE state is not allowed.
To make the tracking somewhat sane, we only promote to OPTIMAL if an
entire image's worth of subresources for a given aspect is transitioned.
The common case for depth-stencil images is 1 mip / 1 layer anyways.
Some other changes are required here:
- Instead of common_layout for the depth image, we need to consult the
command list, which might promote the layout to optimal.
- We make use of render pass compatibility rules which state that we can
change attachment reference layouts as well as initial/finalLayout.
To make this change, a pipeline will fill in a
vkd3d_render_pass_compat struct.
- A command list has a dsv_plane_optimal_mask which keeps track
of the plane aspects we have promoted to OPTIMAL, and we know cannot
be read by shaders.
The desired optimal mask is (existing optimal | PSO write).
The initial existing optimal is inherited from the command list's
tracker.
- RTV/DSV/views no longer keep track of VkImageLayout. This is
unnecessary since we always deduce image layout based on context.
Overall, this shows a massive gain in HZD benchmark (RADV, 1440p ultimate, ~16% FPS on RX 6800).

Idea is to keep track of scenarios where we know a resource's aspect is
known to be in a OPTIMAL state. Based on this, we can override the image

- Honor resource barriers for resource states which cannot automatically
decay or promote. This includes COLOR_ATTACHMENT, UNORDERED_ACCESS and
VRS image. If SIMULTANEOUS_ACCESS is used, we can still promote, and
we handle that by setting common layout to GENERAL for these resources.
- Avoid redundant barriers in render passes since normal resource
barriers will always make sure we are already in
COLOR_ATTACHMENT_OPTIMAL.
- Do not force GENERAL layout if resource has UNORDERED_ACCESS flag set.
As this is not a promotable state, we have to explicitly transition
into it. I tested this on validation layers, where even COMMON state
refuses to promote to UAV state. The exception here of course is
SIMULTANOUS_ACCESS, but we handle that properly now.
- Verify that UAV or SIMULTANEOUS access is not used together with DSV
state. This is explicitly banned in the API docs.
- Actually emit image barriers. Batch the image transitions as that's
what D3D12 docs encourage app developers to do, and it also expects
that drivers can optimize this. Ensure that we respect the in-order
resource barrier rules by splitting batches if there are overlaps in
the transitions.
- Ensure that correct image layout is used when clearing a suspended
render pass attachment.

The spec is pretty clear that it's invalid usage. Return E_INVALIDARG
like native drivers.
This is a workaround for the inventory GPU hang with Cyberpunk 2077
which is actually a game bug. Luckily the game handles this error
properly.
The problem is that the game always assume that an image with 2 mips
is smaller than the same image but with 6 mips. This is not always
true if the swizzle mode is different and a recent Mesa update changed
that. Then the game creates a D3D12 heap that is too small and this
triggered a memory violation and then a GPU hang with RADV.

In control flow, we can force LOD 0.0 to avoid undefined result when
games sample with implicit LOD in non-quad uniform control flow.
Behavior on different implementations is:
- Helper lanes come to life and interpolate shader input.
- LOD is clamped to 0.0 in divergent control flow.
This hack is not safe in general, since we force 0.0 even when the
control flow is quad uniform.
This is the most practical solution for the problem for now.
