Without using VK_EXT_robustness2, we can't consider the 'enabled' (not
null) vertex buffers as dynamic state, as this leads to invalid Vulkan
state. Move this to static state that is always hashed and compared in
the pipeline key.
The bits for enabled vertex buffers are moved into the attribute state
bitfield. This is not 'correct' as it's not an attribute state, but that
struct has bits to spare, and it's used in an array of 32 elements (the
exact same number of vertex buffer bindings).
Most of the time people write code that always returns a value,
terminates execution, throws an exception, or uses an unconventional
jump primitive.
This is not always true when we build without asserts on mainline builds.
To avoid introducing undefined behavior on our most used builds, enforce
this warning signalling an error and stopping the build from shipping.
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.
On Apple platforms, FALSE and TRUE are defined as macros by
<mach/boolean.h>, which is included by various system headers.
Note that there appear to be no actual users of the names to fix up.
Migrates the video core code closer to enabling variable shadowing
warnings as errors.
This primarily sorts out shadowing occurrences within the Vulkan code.
This was only necessary for use with the
avcodec_decode_video2/avcoded_decode_audio4 APIs which are also
deprecated.
Given we use avcodec_send_packet/avcodec_receive_frame, this isn't
necessary, this is even indicated directly within the FFmpeg API changes
document here on 2017-09-26:
https://github.com/FFmpeg/FFmpeg/blob/master/doc/APIchanges#L410
This prevents our code from breaking whenever we update to a newer
version of FFmpeg in the future if they ever decide to fully remove this
API member.
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.
- Use .at() instead of raw indexing when dealing with untrusted indices.
- For the special case of WaitFence with syncpoint id UINT32_MAX,
instead of crashing, log an error and ignore. This is what I get when
running Super Mario Maker 2.
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.
This reduces the overhead of bounds checking on each element.
It won't reduce the cost of allocation because usually this vector's
capacity is usually large enough to hold whatever we push to it.
It's deprecated in the language to autogenerate these if the destructor
for a type is specified, so we can explicitly specify how we want these
to be generated.
The API of VP9 exposes a WasFrameHidden() function which accesses this
member. Given the constructor previously didn't initialize this member,
it's a potential vector for an uninitialized read.
Instead, we can initialize this to a deterministic value to prevent that
from occurring.
This implements texture cube arrays with shadow comparisons but doesn't
fix the asserts related to it.
Fixes out of bounds reads on swizzle constructors and makes them use
bounds checked ::at instead of the unsafe operator[].
This commit aims to implement the NVDEC (Nvidia Decoder) functionality, with video frame decoding being handled by the FFmpeg library.
The process begins with Ioctl commands being sent to the NVDEC and VIC (Video Image Composer) emulated devices. These allocate the necessary GPU buffers for the frame data, along with providing information on the incoming video data. A Submit command then signals the GPU to process and decode the frame data.
To decode the frame, the respective codec's header must be manually composed from the information provided by NVDEC, then sent with the raw frame data to the ffmpeg library.
Currently, H264 and VP9 are supported, with VP9 having some minor artifacting issues related mainly to the reference frame composition in its uncompressed header.
Async GPU is not properly implemented at the moment.

These compiler flags aren't shared with clang, so specifying these flags
unconditionally can lead to a bit of warning spam.
While we're in the area, we can also enable -Wunused-but-set-parameter
given this is almost always a bug.
This emulates the behavior we get on GLSL with regular SSBOs with a
pointer + length pair. It aims to be consistent with the crashes we
might get.
Out of bounds stores are ignored. Atomics are ignored and return zero.
Reads return zero.
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.
TMML takes an array argument that has no known meaning, this one appears
as the first component in gpr8 followed by s, t and r. Skip this
component when arrays are being used. Also implement CUBE texture types.
- Used by Pikmin 3: Deluxe Demo.
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.
When HEADER_GENERATOR was included in the DEPENDS section of custom
commands, msbuild assumed this was always modified. Changing this file
is not common so we can remove it from there.
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.
