Subject: [PATCH 02/19] ACPI, APEI, ERST, Fix erst-dbg long record reading issue
Date: Tue, 02 Aug 2011 18:14:35 -0400 [thread overview]
Message-ID: <d37afc50e618271839f001ea653949eefc728167.1312323131.git.len.brown@intel.com> (raw)
In-Reply-To: <1312323292-2986-1-git-send-email-lenb@kernel.org>
In-Reply-To: <ca7cc5110a313a609da40ae948978a585352564b.1312323131.git.len.brown@intel.com>
From: Chen Gong <gong.chen@linux.intel.com>
When we debug ERST table with erst-dbg, if the error record in ERST
table is too long(>4K), it can't be read out. So this patch increases
the buffer size to 16K to ensure such error records can be read from
ERST table.
