Subject: [PATCH 4/6] x86/insn: Add misc instructions to x86 instruction decoder
Date: Thu,  2 Dec 2021 11:50:27 +0200	[thread overview]
Message-ID: <20211202095029.2165714-5-adrian.hunter@intel.com> (raw)
In-Reply-To: <20211202095029.2165714-1-adrian.hunter@intel.com>

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 instructions to x86 instruction decoder:

	User Interrupt

		clui
		senduipi
		stui
		testui
		uiret

	Prediction history reset

		hreset

	Serialize instruction execution

		serialize

	TSX suspend load address tracking

		xresldtrk
		xsusldtrk

Document Number: 319433-044

Example using perf tools' x86 instruction decoder test:

  $ perf test -v "x86 instruction decoder" |& grep -i hreset
  Decoded ok: f3 0f 3a f0 c0 00           hreset $0x0
  Decoded ok: f3 0f 3a f0 c0 00           hreset $0x0
