Subject: [PATCH v1 5/6] ArmVirtPkg: Kvmtool: Increase primary core stack size
Date: Thu, 18 May 2023 10:09:34 +0100 [thread overview]
Message-ID: <20230518090935.10984-6-sami.mujawar@arm.com> (raw)
In-Reply-To: <20230518090935.10984-1-sami.mujawar@arm.com>
The patch "f07a9df9af60 ArmVirtPkg: Enable stack guard"
enabled stack overflow detection for ArmVirtPkg. Following
this patch, running UEFI shell command 'dmpstore' resulted
in a crash indicating a stack overflow. Invoking 'dmpstore'
results in recursive calls to CascadeProcessVariables ()
which apparently consumes the available stack space and
overflows.
Therefore, increase the primary core stack size.
