This allows the PEI core to report the maximum temporary SEC/PEI stack usage on the DEBUG_INFO level, in the PeiCheckAndSwitchStack() function [MdeModulePkg/Core/Pei/Dispatcher/Dispatcher.c]: * Normal boot: > Temp Stack : BaseAddress=0x814000 Length=0x4000 > Temp Heap : BaseAddress=0x810000 Length=0x4000 > Total temporary memory: 32768 bytes. > temporary memory stack ever used: 5080 bytes. <---- > temporary memory heap used for HobList: 8080 bytes. > temporary memory heap occupied by memory pages: 0 bytes. * S3 resume (no SMM / PEI decompression) > Temp Stack : BaseAddress=0x814000 Length=0x4000 > Temp Heap : BaseAddress=0x810000 Length=0x4000 > Total temporary memory: 32768 bytes. > temporary memory stack ever used: 5048 bytes. <---- > temporary memory heap used for HobList: 7112 bytes. > temporary memory heap occupied by memory pages: 0 bytes. I unit-tested this change by transitorily adding an infinite loop right after the "rep stosq", and dumping the guest's temp SEC/PEI RAM (32KB currently) while the guest was stuck in the loop. The dump includes one dword from before and after the temp SEC/PEI RAM: > $ virsh qemu-monitor-command GUEST_NAME --hmp 'xp /8194wx 0x80FFFC' > > 000000000080fffc: 0x00000000 0x5aa55aa5 0x5aa55aa5 0x5aa55aa5 > 000000000081000c: 0x5aa55aa5 0x5aa55aa5 0x5aa55aa5 0x5aa55aa5 > ... > 0000000000817fec: 0x5aa55aa5 0x5aa55aa5 0x5aa55aa5 0x5aa55aa5 > 0000000000817ffc: 0x5aa55aa5 0x00000000 Cc: Ard Biesheuvel <ard.biesheuvel@linaro.org> Cc: Jordan Justen <jordan.l.justen@intel.com> Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=747 Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Reviewed-by: Jordan Justen <jordan.l.justen@intel.com> |
