From 384c0076bcf1df739c3e0b51d6415538b9ad3123 Mon Sep 17 00:00:00 2001 From: jeromew Date: Fri, 3 Apr 2026 15:05:14 +0200 Subject: [PATCH] docs: Update build.md: HSA_OVERRIDE_GFX_VERSION clarification (#21331) The `HSA_OVERRIDE_GFX_VERSION` variable can be used in ROCm to override an unsupported target architecture with a similar but supported target architecture. This does not and has never worked on Windows. I think the clarification could avoid driving Windows people towards this solution that does not work. --- docs/build.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/docs/build.md b/docs/build.md index ef086ff434..616a838def 100644 --- a/docs/build.md +++ b/docs/build.md @@ -389,7 +389,7 @@ You can download it from your Linux distro's package manager or from here: [ROCm The environment variable [`HIP_VISIBLE_DEVICES`](https://rocm.docs.amd.com/en/latest/understand/gpu_isolation.html#hip-visible-devices) can be used to specify which GPU(s) will be used. -If your GPU is not officially supported you can use the environment variable [`HSA_OVERRIDE_GFX_VERSION`] set to a similar GPU, for example 10.3.0 on RDNA2 (e.g. gfx1030, gfx1031, or gfx1035) or 11.0.0 on RDNA3. +If your GPU is not officially supported you can use the environment variable [`HSA_OVERRIDE_GFX_VERSION`] set to a similar GPU, for example 10.3.0 on RDNA2 (e.g. gfx1030, gfx1031, or gfx1035) or 11.0.0 on RDNA3.
