Subject: [Patch v5 03/48] UefiCpuPkg/CpuS3DataDxe: Move StartupVector allocation to EndOfDxe()
Date: Tue,  2 Aug 2016 16:59:03 +0800	[thread overview]
Message-ID: <1470128388-17960-4-git-send-email-jeff.fan@intel.com> (raw)
In-Reply-To: <1470128388-17960-1-git-send-email-jeff.fan@intel.com>

Currently, we will allocate StartupVector buffer under 1MB at entry point
function. But some modules may allocate some hard code address under 1MB.
For example, LegacyBiosDxe driver tries to manage some legacy range under
640KB.

To avoid the conflicts, we move StartupVector buffer allocation to End Of
DXE event callback function.

v4:
  Update the Context parameter is used as a pointer to AcpiCpuDataEx, then
  we needn't to add the global variable.
