Subject: [igt-dev] [PATCH i-g-t v4 0/1] Support to assemble CB kernel for gen7
Date: Fri, 21 Feb 2020 00:22:42 -0800 [thread overview]
Message-ID: <20200221082243.19807-1-akeem.g.abodunrin@intel.com> (raw)
Summary
-------
This is patch adds support to assemble CB kernel for gen7 and gen7.5
devices. It is needed for "Security mitigation for Intel Gen7/7.5 HWs"
Intel ID: PSIRT-TA-201910-001/CVEID: CVE-2019-14615.
