From 09d70ded6c566fd00886be32c26d0b2004ef239c Mon Sep 17 00:00:00 2001 From: "David E. Box" Date: Wed, 10 Apr 2024 19:58:54 -0700 Subject: [PATCH] tools/arch/x86/intel_sdsi: Fix meter_certificate decoding MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fix errors in the calculation of the start position of the counters and in the display loop. While here, use a #define for the bundle count and size. Fixes: 7fdc03a7370f ("tools/arch/x86: intel_sdsi: Add support for reading meter certificates") Signed-off-by: David E.
