Bug ID: 98021 Summary: Applications and games crash after opengl version overrides Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: step2back+freedesktop@gmail.com QA Contact: dri-devel@lists.freedesktop.org
I should set mesa version to smooth play in alien isolation ( https://bugs.freedesktop.org/show_bug.cgi?id=93144#c35 ). I set "MESA_GL_VERSION_OVERRIDE=4.3 MESA_GLSL_VERSION_OVERRIDE=430". Appications and games start carsh in gl initialization. Some examples: steam, 0ad. glxgear shows black screen.
I use software from oibaf ppa:
Extended renderer info (GLX_MESA_query_renderer): Vendor: X.Org (0x1002) Device: AMD CAPE VERDE (DRM 2.43.0 / 4.4.0-41-generic, LLVM 3.9.0) (0x683d) Version: 12.1.0 Accelerated: yes Video memory: 1024MB Unified memory: no Preferred profile: core (0x1) Max core profile version: 4.3 Max compat profile version: 4.3 Max GLES1 profile version: 1.1 Max GLES[23] profile version: 3.0
MESA_DEBUG=1 prints
Mesa: User error: GL_INVALID_ENUM in glGetString(GL_EXTENSIONS)
I'm curious why mesa does not set 4.3 already. According mesamatrix (by features.txt) there are all extensions implemented for radeonsi.

--- Comment #1 from Nicolai Hähnle nhaehnle@gmail.com --- Hi Stepan, it's called an override for a reason. When you enable it, you're operating outside of the supported parameters, and shouldn't be surprised when something crashes. Don't report a bug for something like that.
That said, radeonsi has supported OpenGL 4.3 for several months now. For SI-based cards like yours, you need a more recent kernel. The radeon module of older kernels lacks some of the functionality that is required for compute shaders.

--- Comment #2 from Stepan Bakshaev step2back+freedesktop@gmail.com --- I got it. linux 4.8 is enough for enable 4.3 in stock. Sorry for bother you. I check time by time https://www.x.org/wiki/RadeonFeature/. it does not mention about all requirements for opengl 4.3. There is only llmv 3.8 as requirements. I saw Alex Deucher updates that wiki page. May be he will add next time linux 4.8 in footnotes.
Thank you and whole team for pushing radeon driver forward!
