During intensive workloads, this handshake intermittently fails for V3D&#39;s master ASB on BCM2711, resulting in &#34;Failed to disable ASB master for v3d&#34; errors during runtime PM suspend. As a consequence, the failed power-off leaves V3D in a broken state, leading to bus faults or system hangs on later accesses.</p> <p>As the timeout is insufficient in some scenarios, increase the polling timeout from 1us to 5us, which is still negligible in the context of a power domain transition. Also, replace the open-coded ktime_get_ns()/ cpu_relax() polling loop with readl_poll_timeout_atomic().</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>pmdomain: bcm: bcm2835-power: Increase ASB control timeout</p> <p>The bcm2835_asb_control() function uses a tight polling loop to wait for the ASB bridge to acknowledge a request.
