这段文字是关于 Linux 内核中一个特定漏洞的修复描述。以下是该段落的中文翻译： 在 Linux 内核中，以下漏洞已得到修复： drm/amdgpu：在复位时强制完成 KIQ 环的栅栏（fence） 与 MES 调度器环类似，KIQ 环设置了 并使用轮询栅栏（polling fence），因此它会被 中的“强制完成”循环跳过。其硬件栅栏（hw fence）的值存储在 wb（GTT）内存中，在 MODE1 复位后依然保留；而 却仍在持续增加。因此，在复位之后，第一次提交 KIQ 任务时，可能会在一个永远不会被写回的

Vulnerability Title
drm/amdgpu: force complete the KIQ ring fences on reset
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: force complete the KIQ ring fences on reset Like the MES scheduler ring, the KIQ ring sets no_scheduler = true and uses a polling fence, so it is skipped by the force-completion loop in amdgpu_device_pre_asic_reset(). Its hw fence value lives in wb (GTT) memory and survives a MODE1 reset while fence_drv.sync_seq keeps advancing, so after a reset the first KIQ submission can poll forever on a seq that is never written back. Force complete the KIQ ring fences too so their hw fence is realigned to sync_seq.
