This is a better default for most games, yielding better performance and less graphical issues.

There was still a code path that could wait on a timeline semaphore tick that would never be signalled. While we are at it, make use of more STL algorithms.

Games can bind a null index buffer (size=0) where all indices are evaluated as zero. VK_EXT_robustness2 doesn't support this and all drivers segfault when a null index buffer is passed to vkCmdBindIndexBuffer. Workaround this by creating a 4 byte buffer and filling it with zeroes. If it's read out of bounds, robustness takes care of returning zeroes as indices.

Bind extra bytes beyond the guest API's bound range. This is due to some games like Astral Chain operating out of bounds. Binding the whole map range would be technically correct, but games have large maps that make this approach unaffordable for now.

Avoids waiting idle while the GPU finishes to do work, and fixes an issue where we'd wait forever if a single command buffer (logic tick) all the data.

Due to BindBufferRangeNV limitations and poor quality code emission from our side, assembly shaders are currently slower than GLSL. Their build time and feature advantages are still relevant, but they are outweighted by their runtime performance.

Remove unused interop code from the OpenGL backend.

Sacrify runtime performance to avoid generating kernel exceptions on Windows due to our abusive aliasing of interop buffer objects.

Detect when a memory region has been joined several times and increase the size of the created buffer on those instances. The buffer is assumed to be a "stream buffer", increasing its size should stop us from constantly recreating it and fragmenting memory.

Allow adding functionality to each function without making CreateBuffer more complex.

Ports from OpenGL the optimization to skip small 3D uniform buffer uploads. This will take advantage of the previously introduced stream buffer. Fixes instances where the staging buffer offset was being ignored.
-

This uses a ring buffer similar to OpenGL's stream buffer for small uploads. This stops us from allocating several small buffers, reducing memory fragmentation and cache locality. It uses dedicated allocations when possible.

Reimplement the buffer cache using cached bindings and page level granularity for modification tracking. This also drops the usage of shared pointers and virtual functions from the cache. - Bindings are cached, allowing to skip work when the game changes few bits between draws. - OpenGL Assembly shaders no longer copy when a region has been modified from the GPU to emulate constant buffers, instead GL_EXT_memory_object is used to alias sub-buffers within the same allocation. - OpenGL Assembly shaders stream constant buffer data using glProgramBufferParametersIuivNV, from NV_parameter_buffer_object. In theory this should save one hash table resolve inside the driver compared to glBufferSubData. - A new OpenGL stream buffer is implemented based on fences for drivers that are not Nvidia's proprietary, due to their low performance on partial glBufferSubData calls synchronized with 3D rendering (that some games use a lot). - Most optimizations are shared between APIs now, allowing Vulkan to cache more bindings than before, skipping unnecesarry work. This commit adds the necessary infrastructure to use Vulkan object from OpenGL. Overall, it improves performance and fixes some bugs present on the old cache. There are still some edge cases hit by some games that harm performance on some vendors, this are planned to be fixed in later commits.

Workaround an issue on Nvidia where creating a Vulkan instance from an active OpenGL thread disables threaded optimization on the driver. This optimization is important to have good performance on Nvidia OpenGL.

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.

Ensure the behavior of the previous commit in tests.

ReinUsesLisp authored
Some games usually write memory pages currently used by the GPU, causing rendering issues (e.g. flashing geometry and shadows on Link's Awakening). To workaround this issue, Guest CPU writes are delayed until the command buffer finishes processing, but the pages are updated immediately. The overall behavior is: - CPU writes are cached until they are flushed, they update the page state, but don't change the modification state. Cached writes stop pages from being flushed, in case games have meaningful data in it. - Command processing writes (e.g. push constants) update the page state and are marked to the command processor as dirty. They don't remove the state of cached writes.

This implements KScopedReservation, allowing resource limit reservations to be more HW accurate, and release upon failure without requiring too many conditionals.

* kernel: Unify result codes Drop the usage of ERR_NAME convention in kernel for ResultName. Removed seperation between svc_results.h & errors.h as we mainly include both most of the time anyways. * oops * rename errors to svc_results
