https://bugzilla.tianocore.org/show_bug.cgi?id=624 reports memory protection crash in PiSmmCpuDxeSmm, Ia32 build with RAM above 4GB (of which 2GB are placed in 64-bit address). It is because UEFI builds identity mapping page tables, >4G address is not supported at Ia32 build. This patch is to get the PhysicalAddressBits that is used to build in PageTbl.c(Ia32/X64), and use it to check whether the address is supported or not in ConvertMemoryPageAttributes(). With this patch, the debug messages will be like below. UefiMemory protection: 0x0 - 0x9F000 Success UefiMemory protection: 0x100000 - 0x807000 Success UefiMemory protection: 0x808000 - 0x810000 Success UefiMemory protection: 0x818000 - 0x820000 Success UefiMemory protection: 0x1510000 - 0x7B798000 Success UefiMemory protection: 0x7B79B000 - 0x7E538000 Success UefiMemory protection: 0x7E539000 - 0x7E545000 Success UefiMemory protection: 0x7E55A000 - 0x7E61F000 Success UefiMemory protection: 0x7E62B000 - 0x7F6AB000 Success UefiMemory protection: 0x7F703000 - 0x7F70B000 Success UefiMemory protection: 0x7F70F000 - 0x7F778000 Success UefiMemory protection: 0x100000000 - 0x180000000 Unsupported Cc: Jiewen Yao <jiewen.yao@intel.com> Cc: Laszlo Ersek <lersek@redhat.com> Cc: Eric Dong <eric.dong@intel.com> Originally-suggested-by: Jiewen Yao <jiewen.yao@intel.com> Reported-by: Laszlo Ersek <lersek@redhat.com> Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Star Zeng <star.zeng@intel.com> Reviewed-by: Jiewen Yao <jiewen.yao@intel.com> Tested-by: Laszlo Ersek <lersek@redhat.com> |
