Linux does not report the driver version. It does report the OpenGL
version. This change will check the OpenGL version to enable the HQ
normal work around.
THe high quality normals work around is enabled for Polaris cards using
the official drivers. Since driver version 2.11.2 they fail to render
using low quality normals.
The detection of polaris cards is done by matching the opengl renderer.
The renderer strings have been extracted from various reports linked to
{T82856} but isn't complete as some reports are missing the exact
renderer as users don't always report via the help menu.
This is a workaround for T80804.
There's a startup crash that happens on 2.91.0 on Windows, an `EXCEPTION_ACCESS_VIOLATION`
on `atio6axx.dll`. It is triggered by `glClear` on the `detect_mip_render_workaround`
function. The workaround moves the function after the device/driver workaround section and
sets the flag to the affected one to avoid running the check.
It is deprecated hardware that has not meet the minimum requirements since 2.79, but is
still usable and this extends its usability a bit before the cards are finally blacklisted.

Since Blender 2.91 the TeraScale 2 based cards crash during startup.
This patch will show the user a screen that the platform they are using
isn't supported.
The GPUs have been carefully handpicked from dozens of reports. T83124,
T83127, T83103, T83091, T83045, T83065, T82750, T82889, T82925, T82640,
T82429, T82436, T82446.
This wraps the functionality used to speedup EEVEE volumetrics.
This touches the rendering code of EEVEE as it should fix a mis-usage of
the GL barrier. The barrier changed type and location, removing an
unused barrier.
This makes it possible to disable all the extensions when forcing
workarounds.
Also it will allow future options to selectively disable each extension
to know which one is buggy.
This is to improve debugging on older hardware that may not support
4.3 debug capabilities (like Macs).
This avoids sprinkling glGetErrors manually. This might still be needed
to find the root cause since not all functions are covered.
This overrides the functions pointers that GLEW have already init.
This is only enabled if using --debug-gpu option and the debug extension
are not available.
This also cleanup the usage of GLContext::debug_layer_support and use
wrapper to set object labels.
This is part of the Vulkan task T68990.
This commits changes a few things:
- Rename extensions to capabilities (but left the file name untouched).
- Cubemap mip render workaround detection is rewritten using gl
commands to avoid using the GPU API before initialization.
- Put all the capabilities that are only relevant for the GL backend
inside GLContext as static variables.
- Cleanup the names of the limit variables.
- Separate all GL related workaround search inside the GL module.
Part of the vulkan implementation T68990.
Pretty straight forward. Just move the GL code inside the GLBackend and
make the GPUPlatformGlobal a class object.
