From e67b8afcb6d86f1bc6a69e4e52cf9dcfe636f995 Mon Sep 17 00:00:00 2001 From: Frank Min Date: Tue, 5 Aug 2025 22:30:54 +0800 Subject: drm/amdgpu: Add PSP fw version check for fw reserve GFX command The fw reserved GFX command is only supported starting from PSP fw version 0x3a0e14 and 0x3b0e0d. Older versions do not support this command. Add a version guard to ensure the command is only used when the running PSP fw meets the minimum version requirement. This ensures backward compatibility and safe operation across fw revisions.
