[edk2-devel] [PATCH v1 0/1] MdeModulePkg/Core: Fix the potential hang of calling SetTimer.

Posted by Ying-Tsun Huang via groups.io 1 year, 7 months ago

When calling SetTimer with Type is not TimerCancel and TriggerTime is 0,
gTimer is used to get the timer period. However, gTimer is NULL before
EFI_TIMER_ARCH_PROTOCOL is installed. Adding the check of gTimer and
return EFI_NOT_READY to avoid the hang.
