Sometimes the UEFI memory map changes between GetMemoryMap() and ExitBootServices(), making the MapKey value incorrect. Per the UEFI spec, the memory map should then be fetched again and exiting retried.

I am a UEFI/BIOS developer. We UEFI PXE boot dozens of times per night. We have run into this error more than a couple of times. We have also done thousands of UEFI PXE boots with debug statements to prove that the patch works.

Hello, I'm booting linux-3.16-686-pae kernel (32-bit) via syslinux.efi 64-bit version. After boot linux sees only 2.5G of RAM while system has 32G installed. If I boot the same kernel with GRUB64 efi instead of syslinux then amount of RAM available to linux is 32G. Is this a bug or I'm missing something? syslinux.cfg: label live-686-pae menu label Linux (686-pae) menu

Yes, I think so. The integer really means the same as EFI's ExitBootServices. Matt Fleming <matt at console-pimps.org> wrote: >On Fri, 02 Aug, at 07:50:57AM, H.

Hi all, I'm terribly sorry that I cannot follow emails in my gmail inbox, since gmail is blocked by China govement, as many of you may have already known. I'm a HP employee in China and we are going through the splitting process, so the blade server I was using were packed up and should be moved into a new room. I will try the latest source if possible. Thank you very much for your works.

Hi all, I added support for the allocsize function attribute to our compiler (LDC), thinking that that would enable removal of function calls when the allocated memory is not used. For example: ``` declare i8* @my_malloc(i32) allocsize(0) define void @test_malloc() { %1 = call i8* @my_malloc(i32 100) ret void } ``` I thought the my_alloc call in test_malloc would be removed, but `opt -O3`

Hi all, consider the following function from Core.cpp in LLVM 9.0.0: LLVMValueRef LLVMBuildMalloc(LLVMBuilderRef B, LLVMTypeRef Ty, const char *Name) { Type* ITy = Type::getInt32Ty(unwrap(B)->GetInsertBlock()->getContext()); Constant* AllocSize = ConstantExpr::getSizeOf(unwrap(Ty)); AllocSize = ConstantExpr::getTruncOrBitCast(AllocSize, ITy);
