From a6ea1142dee66f054a7ce51ebd053ef5ad976227 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Thu, 2 Dec 2021 11:50:26 +0200 Subject: perf/tests: Add misc instructions to the x86 instruction decoder test The x86 instruction decoder is used for both kernel instructions and user space instructions (e.g. uprobes, perf tools Intel PT), so it is good to update it with new instructions. Add the following instructions to the x86 instruction decoder test: User Interrupt clui senduipi stui testui uiret Prediction history reset hreset Serialize instruction execution serialize TSX suspend load address tracking xresldtrk xsusldtrk A subsequent patch adds the instructions to the instruction decoder.
