* general: Add setting shader_backendlat9nq2021-07-231-4/+6
| | | | | | | | | | | | | | | | GLASM is getting good enough that we can move it out of advanced graphics settings. This removes the setting `use_assembly_shaders`, opting for a enum class `shader_backend`. This comes with the benefits that it is extensible for additional shader backends besides GLSL and GLASM, and this will work better with a QComboBox. Qt removes the related assembly shader setting from the Advanced Graphics section and places it as a new QComboBox in the API Settings group. This will replace the Vulkan device selector when OpenGL is selected. Additionally, mark all of the custom anisotropic filtering settings as "WILL BREAK THINGS", as that is the case with a select few games.

* gl_device: Block async shaders on AMD and Intellat9nq2021-03-211-1/+13
| | | | | | | | Currently, the Windows versions of the Intel OpenGL driver and the AMD proprietary OpenGL driver do not properly support (or in fact degrade) when asynchronous shader compilation is enabled. This blocks specifically those drivers from using this feature. This affects AMDGPU-PRO on Linux, and AMD's and Intel's OpenGL drivers on Windows.

* video_core: Reimplement the buffer cacheReinUsesLisp2021-02-131-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* renderer_opengl: Avoid precompiled cache and force NV GL cache directoryReinUsesLisp2021-01-211-0/+1
| | | | | | | | | | | | | | Setting __GL_SHADER_DISK_CACHE_PATH we can force the cache directory to be in yuzu's user directory to stop commonly distributed malware from deleting our driver shader cache. And by setting __GL_SHADER_DISK_CACHE_SKIP_CLEANUP we can have an unbounded shader cache size. This has only been implemented on Windows, mostly because previous tests didn't seem to work on Linux. Disable the precompiled cache on Nvidia's driver. There's no need to hide information the driver already has in its own cache.
* gl_texture_cache: Avoid format views on Intel and AMDReinUsesLisp2021-01-041-0/+4
| | | | | | | Intel and AMD proprietary drivers are incapable of rendering to texture views of different formats than the original texture. Avoid creating these at a cache level. This will consume more memory, emulating them with copies.

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 maintainability and performance.

* configuration: implement per-game configurations (#4098)lat9nq2020-07-101-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Switch game settings to use a pointer In order to add full per-game settings, we need to be able to tell yuzu to switch to using either the global or game configuration. Using a pointer makes it easier to switch. * configuration: add new UI without changing existing funcitonality The new UI also adds General, System, Graphics, Advanced Graphics, and Audio tabs, but as yet they do nothing. This commit keeps yuzu to the same functionality as originally branched. * configuration: Rename files These weren't included in the last commit. Now they are. * configuration: setup global configuration checkbox Global config checkbox now enables/disables the appropriate tabs in the game properties dialog. The use global configuration setting is now saved to the config, defaulting to true. This also addresses some changes requested in the PR. * configuration: swap to per-game config memory for properties dialog Does not set memory going in-game. Swaps to game values when opening the properties dialog, then swaps back when closing it. Uses a `memcpy` to swap. Also implements saving config files, limited to certain groups of configurations so as to not risk setting unsafe configurations. * configuration: change config interfaces to use config-specific pointers When a game is booted, we need to be able to open the configuration dialogs without changing the settings pointer in the game's emualtion. A new pointer specific to just the configuration dialogs can be used to separate changes to just those config dialogs without affecting the emulation. * configuration: boot a game using per-game settings Swaps values where needed to boot a game. * configuration: user correct config during emulation Creates a new pointer specifically for modifying the configuration while emulation is in progress. Both the regular configuration dialog and the game properties dialog now use the pointer Settings::config_values to focus edits to the correct struct. * settings: split Settings::values into two different structs By splitting the settings into two mutually exclusive structs, it becomes easier, as a developer, to determine how to use the Settings structs after per-game configurations is merged. Other benefits include only duplicating the required settings in memory. * settings: move use_docked_mode to Controls group `use_docked_mode` is set in the input settings and cannot be accessed from the system settings. Grouping it with system settings causes it to be saved with per-game settings, which may make transferring configs more difficult later on, especially since docked mode cannot be set from within the game properties dialog. * configuration: Fix the other yuzu executables and a regression In main.cpp, we have to get the title ID before the ROM is loaded, else the renderer will reflect only the global settings and now the user's game specific settings. * settings: use a template to duplicate memory for each setting Replaces the type of each variable in the Settings::Values struct with a new class that allows basic data reading and writing. The new struct Settings::Setting duplicates the data in memory and can manage global overrides per each setting. * configuration: correct add-ons config and swap settings when apropriate Any add-ons interaction happens directly through the global values struct. Swapping bewteen structs now also includes copying the necessary global configs that cannot be changed nor saved in per-game settings. General and System config menus now update based on whether it is viewing the global or per-game settings. * settings: restore old values struct No longer needed with the Settings::Setting class template. * configuration: implement hierarchical game properties dialog This sets the apropriate global or local data in each setting. * clang format * clang format take 2 can the docker container save this? * address comments and style issues * config: read and write settings with global awareness Adds new functions to read and write settings while keeping the global state in focus. Files now generated per-game are much smaller since often they only need address the global state. * settings: restore global state when necessary Upon closing a game or the game properties dialog, we need to restore all global settings to the original global state so that we can properly open the configuration dialog or boot a different game. * configuration: guard setting values incorrectly This disables setting values while a game is running if the setting is overwritten by a per game setting. * config: don't write local settings in the global config Simple guards to prevent writing the wrong settings in the wrong files. * configuration: add comments, assume less, and clang format No longer assumes that a disabled UI element means the global state is turned off, instead opting to directly answer that question. Still however assumes a game is running if it is in that state. * configuration: fix a logic error Should not be negated * restore settings' global state regardless of accept/cancel Fixes loading a properties dialog and causing the global config dialog to show local settings. * fix more logic errors Fixed the frame limit would set the global setting from the game properties dialog. Also strengthened the Settings::Setting member variables and simplified the logic in config reading (ReadSettingGlobal). * fix another logic error In my efforts to guard RestoreGlobalState, I accidentally negated the IsPowered condition. * configure_audio: set toggle_stretched_audio to tristate * fixed custom rtc and rng seed overwriting the global value * clang format * rebased * clang format take 4 * address my own review Basically revert unintended changes * settings: literal instead of casting "No need to cast, use 1U instead" Thanks, Morph!

Without a synchronous debug output (single threaded driver), it's likely that the driver will crash in the first blocking call.

| * gl_device: Reserve at least 4 image bindings for fragment stageMorph2020-06-161-6/+14
| | | | | | | | | | | | Due to the limitation of GL_MAX_IMAGE_UNITS being low (8) on Intel's and Nvidia's proprietary drivers, we have to reserve an appropriate amount of image bindings for each of the stages. So far games have been observed to use 4 image bindings on the fragment stage (Kirby Star Allies) and 1 on the vertex stage (TWD series). No games thus far in my limited testing used more than 4 images concurrently and across all currently active programs. This fixes shader compilation errors on Kirby Star Allies on OpenGL (GLSL/GLASM)

|/ | | | | | | | | | | | | | | | Skip fast buffer uploads on Nvidia 443.24 Vulkan beta driver on OpenGL. This driver throws the following error when calling BufferSubData or BufferData on buffers that are candidates for fast constant buffer uploads. This is the equivalens to push constants on Vulkan, except that they can access the full buffer. The error: Unknown internal debug message. The NVIDIA OpenGL driver has encountered an out of memory error. This application might behave inconsistently and fail. If this error persists on future drivers, we might have to look deeper into this issue. For now, we can black list it and log it as a temporary solution.

* renderer_opengl: Add assembly program code pathsReinUsesLisp2020-05-191-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add code required to use OpenGL assembly programs based on NV_gpu_program5. Decompilation for ARB programs is intended to be added in a follow up commit. This does **not** include ARB decompilation and it's not in an usable state. The intention behind assembly programs is to reduce shader stutter significantly on drivers supporting NV_gpu_program5 (and other required extensions). Currently only Nvidia's proprietary driver supports these extensions. Add a UI option hidden for now to avoid people enabling this option accidentally. This code path has some limitations that OpenGL compatibility doesn't have: - NV_shader_storage_buffer_object is limited to 16 entries for a single OpenGL context state (I don't know if this is an intended limitation, an specification issue or I am missing something). Currently causes issues on The Legend of Zelda: Link's Awakening. - NV_parameter_buffer_object can't bind buffers using an offset different to zero. The used workaround is to copy to a temporary buffer (this doesn't happen often so it's not an issue). On the other hand, it has the following advantages: - Shaders build a lot faster. - We have control over how floating point rounding is done over individual instructions (SPIR-V on Vulkan can't do this). - Operations on shared memory can be unsigned and signed. - Transform feedbacks are dynamic state (not yet implemented). - Parameter buffers (uniform buffers) are per stage, matching NVN and hardware's behavior. - The API to bind and create assembly programs makes sense, unlike ARB_separate_shader_objects.

| | | | | | | | | | | | | | | | Nvidia's OpenGL driver maps gl(Named)BufferSubData with some requirements to a fast. This path has an extra memcpy but updates the buffer without orphaning or waiting for previous calls. It can be seen as a better model for "push constants" that can upload a whole UBO instead of 256 bytes. This path has some requirements established here: http://on-demand.gputechconf.com/gtc/2014/presentations/S4379-opengl-44-scene-rendering-techniques.pdf#page=24 Instead of using the stream buffer, this commits moves constant buffers uploads to calls of glNamedBufferSubData and from my testing it brings a performance improvement. This is disabled when the vendor is not Nvidia since it brings performance regressions.

Documentation about these can be found here https://developer.nvidia.com/reading-between-threads-shader-intrinsics Instead of using portable ARB instructions I opted to use Nvidia intrinsics because these are the closest we have to how Tegra X1 hardware renders. To stub VOTE on non-Nvidia drivers (including nouveau) this commit simulates a GPU with a warp size of one, returning what is meaningful for the instruction being emulated: * anyThreadNV(value) -> value * allThreadsNV(value) -> value * allThreadsEqualNV(value) -> true ballotARB, also known as "uint64_t(activeThreadsNV())", emits VOTE.ANY Rd, PT, PT; on nouveau's compiler. This doesn't match exactly to Nvidia's code VOTE.ALL Rd, PT, PT; Which is emulated with activeThreadsNV() by this commit. In theory this shouldn't really matter since .ANY, .ALL and .EQ affect the predicates (set to PT on those cases) and not the registers.

| * gl_shader_decompiler: Implement gl_ViewportIndex and gl_Layer in vertex shadersReinUsesLisp2019-07-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit implements gl_ViewportIndex and gl_Layer in vertex and geometry shaders. In the case it's used in a vertex shader, it requires ARB_shader_viewport_layer_array. This extension is available on AMD and Nvidia devices (mesa and proprietary drivers), but not available on Intel on any platform. At the moment of writing this description I don't know if this is a hardware limitation or a driver limitation. In the case that ARB_shader_viewport_layer_array is not available, writes to these registers on a vertex shader are ignored, with the appropriate logging.

* gl_device: Fix TestVariableAoffi testReinUsesLisp2019-06-121-1/+2
| | | | | | | | | | | | This test is intended to be invalid GLSL, but it was being invalid in two points instead of one. The intention is to use a non-immediate parameter in a textureOffset like function. The problem is that this shader was being compiled as a separable shader object and the text was writting to gl_Position without a redeclaration, being invalid GLSL. Address that issue by using a user-defined output attribute.

| | | | | | | | | | | | | | | | | | | | Component indexing on AMD's proprietary driver is broken. This commit adds a test to detect when we are on a driver that can't successfully manage component indexing. It dispatches a dummy draw with just one vertex shader that writes to an indexed SSBO from the GPU with data sent through uniforms, it then reads that data from the CPU and compares the expected output.
