Subject: [PATCH 0/1] pstore/ram: Ensure stable pmsg address with per-CPU ftrace buffers
Date: Tue, 11 Oct 2022 11:36:29 -0700 [thread overview]
Message-ID: <20221011183630.3113666-1-pso@chromium.org> (raw)
From: Paramjit Oberoi <pso@chromium.org>
Hi pstore maintainers,
Resending a little patch from May: without this change, the start
address of pmsg varies with the number of CPUs in the system. This is a
problem for tools that want to manipulate pstore outside a VM (we are
doing this for crash reporting).
