Subject: Clarification about InitializeCpuExceptionHandlers() and TGE bit in hcr_el2
Date: Thu, 28 Sep 2017 11:23:03 +0000	[thread overview]
Message-ID: <DB4PR04MB299A65031A6955BE46EF233F3790@DB4PR04MB299.eurprd04.prod.outlook.com> (raw)

Hi All,

I see that InitializeCpuExceptionHandlers() is called from DxeMain to take over exception handlers and later from ArmCpuDxe.
Is there any specific purpose to call it from two places during dxe phase?

Additionally we are setting TGE bit three times in hcr_el2 during PrePei phase(ArmPlatformPkg/PrePi/AArch64/ArchPrePi.c)
and Twice in Dxe phase: dxemain(),ArmCpuDxe

Please help to clarify or required to be fixed?

Regards,
Vabhav
