From 0b5476b20db65468542beb03e359a4027fa924c5 Mon Sep 17 00:00:00 2001 From: Yeoh Ee Peng Date: Fri, 5 Jul 2019 10:38:54 +0800 Subject: oeqa/runtime/microcode: Enable microcode update test With iucode-tool, identified the selected microcode to be used for microcode update by the specific processor. Compared the updated microcode from dmesg to the selected microcode, test failed if the updated microcode revision does not match the available selected microcode revision from the iucode-tool. Compute int from hexadecimal for comparison based on Naveen Kumar suggestion.
