From 0ef930e1faca6418316e5b9a3b4d1f6ae9e5b240 Mon Sep 17 00:00:00 2001 From: Jonathan Kim Date: Thu, 9 Oct 2025 11:28:19 -0400 Subject: drm/amdgpu: fix hung reset queue array memory allocation By design the MES will return an array result that is twice the number of hung doorbells it can report. i.e. if up k reported doorbells are supported, then the second half of the array, also of length k, holds the HQD information (type/queue/pipe) where queue 1 corresponds to index 0 and k, queue 2 corresponds to index 1 and k + 1 etc ... The driver will use the HDQ info to target queue/pipe reset for hardware scheduled user compute queues.
