[edk2-devel] [PATCH v1 5/6] ArmVirtPkg: Kvmtool: Increase primary core stack size

[Sami Mujawar]

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.
