[PATCH] drm/i915/gen9: Clear residual context state on context switch
by Yang Yingliang 07 Feb '20

07 Feb '20

From: Akeem G Abodunrin <akeem.g.abodunrin(a)intel.com> commit bc8a76a152c5f9ef3b48104154a65a68a8b76946 upstream. Intel ID: PSIRT-TA-201910-001 CVEID: CVE-2019-14615 Intel GPU Hardware prior to Gen11 does not clear EU state during a context switch. This can result in information leakage between contexts. For Gen8 and Gen9, hardware provides a mechanism for fast cleardown of the EU state, by issuing a PIPE_CONTROL with bit 27 set. We can use this in a context batch buffer to explicitly cleardown the state on every context switch. As this workaround is already in place for gen8, we can borrow the code verbatim for Gen9.
