This is because the register, VGACRI-Dx, checked in this API is a scratch register actually controlled by a MCU, named DPMCU, in BMC.</p> <p>These scratch registers are protected by scu-lock. If suc-lock is not off, DPMCU can not update these registers and then host will have soft lockup due to never updated status.</p> <p>DPMCU is used to control DP and relative registers to handshake with host&#39;s VGA driver. Even the most time-consuming task, DP&#39;s link training, is less than 100ms. 200ms should be enough.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>drm/ast: Fix soft lockup</p> <p>There is a while-loop in ast_dp_set_on_off() that could lead to infinite-loop.
