Subject: [PATCH v2 0/1] MdeModulePkg/Core: Fix the potential hang of calling SetTimer.
Date: Thu, 22 Sep 2022 14:07:12 +0800 [thread overview]
Message-ID: <20220922060713.14217-1-ying-tsun.huang@amd.com> (raw)
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.
