Uses mailbox, then immediate for unlocked framerate depending on
support for either. Also adds support for FIFO_RELAXED.
This function now assumes vsync_mode was originially configured to a value
that the driver supports.
vk_swapchain: ChooseSwapPresentMode determines updates
Simplifies swapchain a bit and allows us to change the present mode
during guest runtime.
vk_swapchain: Fix MSVC error
vk_swapchain: Enforce available present modes
Some frontends don't check the value of vsync_mode before comitting it.
Just as well, since a driver update or misconfiguration could problems
in the swap chain.
vk_swapchain: Silence warnings
Silences GCC warnings implicit-fallthrough and shadow, which apparently
are not enabled on clang.
Previously, yuzu would try and guess which vsync mode to use given
different scenarios, but apparently we didn't always get it right. This
exposes the separate modes in a drop-down the user can select.
If a mode isn't available in Vulkan, it defaults to FIFO.
Vulkan for whatever reason does not return VK_ERROR_OUT_OF_DATE_KHR when
the swapchain is the wrong size. Explicity make sure the size is indeed
up to date to workaround this.
This formats all copyright comments according to SPDX formatting guidelines.
Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.
Allows drivers that do not support VK_PRESENT_MODE_MAILBOX_KHR the ability to present at a framerate higher than the monitor's refresh rate when the FPS is unlocked.
The present semaphore is being signalled by the call to acquire the
swapchain image. This semaphore is meant to be waited on when rendering
to the swapchain image. Currently it is waited on when presenting, but
moving its usage to be waited on in the command buffer submission allows
for proper usage of this semaphore.
Fixes the device lost when launching titles on the Intel Linux Mesa driver.
This changes how Scheduler::Flush works. It queues the current command
buffer to be sent to the GPU but does not do it immediately. The Vulkan
worker thread takes care of that. Users will have to use
Scheduler::Flush + Scheduler::WaitWorker to get the previous behavior.
Scheduler::Finish is unchanged.
To avoid waiting on work never queued, Scheduler::Wait sends the current
command buffer if that's what the caller wants to wait.
Instead of using a two step initialization to report errors, initialize
the GPU renderer and rasterizer on the constructor and report errors
through std::runtime_error.
The "VK" prefix predates the "Vulkan" namespace. It was carried around
the codebase for consistency. "VKDevice" currently is a bad alias with
"VkDevice" (only an upcase character of difference) that can cause
confusion. Rename all instances of it.
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.
It's possible that the window is resized from the moment we ask for its
size to the moment a swapchain is created, causing validation issues.
To workaround this Vulkan issue request the capabilities again just
before creating the swapchain, making the race condition less likely.
