From 853eebe6ec4f6a277b8c8fb34da268aca6cf720b Mon Sep 17 00:00:00 2001 From: Tong Liu01 Date: Fri, 27 Oct 2023 11:26:46 +0800 Subject: [PATCH] drm/amdgpu: add unmap latency when gfx11 set kiq resources [why] If driver does not set unmap latency for KIQ, the default value of KIQ unmap latency is zero. When do unmap queue, KIQ will return that almost immediately after receiving unmap command. So, the queue status will be saved to MQD incorrectly or lost in some chance. [how] Set unmap latency when do kiq set resources. The unmap latency is set to be 1 second that is synchronized with Windows driver.
