For listing the available physical devices we can use Vulkan 1.0.
Now that MoltenVK supports 1.1 we can require it for running games.
Add missing documentation.
VKDevice::IsSuitable was not being called. To address this issue, check
suitability before initialization and throw an exception if it fails.
By doing this, we can deduplicate some code on queue searches.
Previosuly we would first search if a present and graphics queue
existed, then on initialization we would search again to find the index.
Report device enumeration errors with exceptions to be consistent with
other initialization related function calls. Reduces the amount of code
to maintain.
Move surface initialization code to a separate file. It's unlikely to
use this code outside of Vulkan, but keeping platform-specific code
(Win32, Xlib, Wayland) in its own translation unit keeps things cleaner.
Move more Vulkan code to report errors with exceptions and report them
through a log before notifying it with an error boolean for backwards
compatibility. In the future we can replace the rasterizer two-step
initialization to always use exceptions.
Initialize debug callbacks (messenger) from a separate file. This allows
sharing code with different backends.
Change our Vulkan error handling to use exceptions instead of error
codes, simplifying the initialization process.
The current texture cache has several points that hurt maintainability
and performance. It's easy to break unrelated parts of the cache
when doing minor changes. The cache can easily forget valuable
information about the cached textures by CPU writes or simply by its
normal usage.The current texture cache has several points that hurt

This commit aims to address those issues.
fmt now automatically prints the numeric value of an enum class member
by default, so we don't need to use casts any more.
Reduces the line noise a bit.
The previous definition was:
#define NUM(field_name) (sizeof(Maxwell3D::Regs::field_name) / sizeof(u32))
In cases where `field_name` happens to refer to an array, Clang thinks
`sizeof(an array value) / sizeof(a type)` is an instance of the idiom
where `sizeof` is used to compute an array length. So it thinks the
type in the denominator ought to be the array element type, and warns if
it isn't, assuming this is a mistake.
In reality, `NUM` is not used to get array lengths at all, so there is no
mistake. Silence the warning by applying Clang's suggested workaround
of parenthesizing the denominator.
Migrates the video core code closer to enabling variable shadowing
warnings as errors.
This primarily sorts out shadowing occurrences within the Vulkan code.
Force early fragment tests when the 3D method is enabled.
The established pipeline cache takes care of recompiling if needed.
This is implemented only on Vulkan to avoid invalidating the shader
cache on OpenGL.
EmuWindow::PollEvents was called from the GPU thread (or the CPU thread
in sync-GPU mode) when swapping buffers. It had three implementations:
- In GRenderWindow, it didn't actually poll events, just set a flag and
emit a signal to indicate that a frame was displayed.
- In EmuWindow_SDL2_Hide, it did nothing.
- In EmuWindow_SDL2, it did call SDL_PollEvents, but this is wrong
because SDL_PollEvents is supposed to be called on the thread that set
up video - in this case, the main thread, which was sleeping in a
busyloop (regardless of whether sync-GPU was enabled). On macOS this
causes a crash.
To fix this:
- Rename EmuWindow::PollEvents to OnFrameDisplayed, and give it a
default implementation that does nothing.
- In EmuWindow_SDL2, do not override OnFrameDisplayed, but instead have
the main thread call SDL_WaitEvent in a loop.
Vulkan has requirements for primitive topologies that don't play nicely
with yuzu's. Since it's only 4 bits, we can move it to fixed state
without changing the size of the pipeline key.
- Fixes a regression on recent Nvidia drivers on Fire Emblem: Three
Houses.
RDNA devices seem to crash when using VK_EXT_extended_dynamic_state in
the latest 20.9.2 proprietary Windows drivers. As a workaround, for now
we block device names corresponding to current RDNA released products.
The old code had a sort function that was invalid and it didn't work as
expected when the base vector had a different order (e.g. renderdoc was
attached).
This sorts devices as expected and fixes a debug assert on MSVC.
The previous fix only partially solved the issue, as only certain GPUs that needed 9 or less MiB subtracted would work (i.e. GTX 980 Ti, GT 730). This takes from DXVK's example to divide `heap_size` by 2 to determine `allocable_size`. Additionally tested on my Quadro K4200, which previously required setting it to 12 to boot.
This is a hack to destroy all HostCounter instances before the base
class destructor is called. The query cache should be redesigned to have
a proper ownership model instead of using shared pointers.
For now, destroy the host counter hierarchy from the derived class
destructor.
This reworks how host<->device synchronization works on the Vulkan
backend. Instead of "protecting" resources with a fence and signalling
these as free when the fence is known to be signalled by the host GPU,
use timeline semaphores.
Vulkan timeline semaphores allow use to work on a subset of D3D12
fences. As far as we are concerned, timeline semaphores are a value set
by the host or the device that can be waited by either of them.
Taking advantange of this, we can have a monolithically increasing
atomic value for each submission to the graphics queue. Instead of
protecting resources with a fence, we simply store the current logical
tick (the atomic value stored in CPU memory). When we want to know if a
resource is free, it can be compared to the current GPU tick.
This greatly simplifies resource management code and the free status of
resources should have less false negatives.
To workaround bugs in validation layers, when these are attached there's
a thread waiting for timeline semaphores.
