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.
Allows some implementations to avoid completely zeroing out the internal
buffer of the optional, and instead only set the validity byte within
the structure.
This also makes it consistent how we return empty optionals.
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.
Now that the GPU is initialized when video backends are initialized,
it's no longer needed to query components once the game is running: it
can be done when yuzu is booting.
This allows us to pass components between constructors and in the
process remove all Core::System references in the video backend.
'driver_id' can only be known on Vulkan 1.1 after creating a logical
device. Move the driver id check to disable
VK_EXT_extended_dynamic_state after the logical device is successfully
initialized.
The Vulkan device will have the extension enabled but it will not be
used.
I made a request on the Xbyak issue tracker to allow some constructors
to be constexpr in order to avoid static constructors from needing to
execute for some of our register constants.
This request was implemented, so this updates Xbyak so that we can make
use of it.
Vertex binding's <stride> is bugged on AMD's proprietary drivers when
using VK_EXT_extended_dynamic_state. Blacklist it for now while we
investigate how to report this issue to AMD.
Add the necessary CMake code to copy the contents in a string source
shader (GLSL or GLASM) to a header file then consumed by video_core
files.
This allows editting GLSL in its own files without having to maintain
them in source files.
For now, only OpenGL presentation shaders are moved, but we can add
GLASM presentation shaders and static SPIR-V generation through
glslangValidator in the future.
