Hello all, hope all is well Was wondering if I'm doing something wrong/missing something. I have pxe+tftp+uefi working between 2 vms. However after the build is done and I reboot, I still come up to pxe b/c tianocore always starts, from what I've seen, with trying PXE first. Great for initial builds :) but I would like to it stop after. In the xml I am pointing to the disk to boot first. if I virsh destory and run qemu directly on the qcow image, the vm comes up as expected and boots into the OS I have tri...

Just pushed a hacky commit[1] to an "efildr_hack" branch at git.zytor.com/users/sha0/syslinux.git The commit message goes: This introduces support for chaining to tianocore's EDK2's DUET's EFILDRs. You should use EFILDR for FAT12, EFILDR16 for FAT16, EFILDR32 or EFILDR64 (depending on the architecture) for FAT32. Usage: chain.c32 efildr=<filename> where <filename> is the appropriate EFILDR filename. Might be handy for anyone wanting to...

I used several versions of qemu supporting OVMF (which is a tianocore, aka UEFI firmware, "bios"), and the result is the same. I used several different (emulated) network cards in the VM, including virtio-net, e1000, rtl8139 -- it makes no difference. Current testing is done using qemu-2.1.2 (from debian jessie package), OVMF 0~20131112.2590861a-2 and ip...

Replying to http://www.syslinux.org/archives/2014-November/022804.html . After about half a year there's a solution to this problem, outlined here: http://lists.nongnu.org/archive/html/qemu-devel/2015-05/msg05348.html It looks like the bugs are in ipxe. The two patches for ipxe are now part of qemu source now so qemu should come with working ipxe roms which allows booting over network in

Hi, until recently, the hvm guest firmware for xen-ia64 was a private binary file owned and delivered by Intel. I have written an open-source implementation based on tianocore.org. The ia64 firmware is roughly speaking EFI. I have also ported tianocore to Qemu/x86. It shouldn''t be hard to port it to x86. Because the sources are big (at least 40MB) and the buildery is not easy (build tools are java-based), I don''t think it should be included in the...

...quot;is not required on initial start up", but as a guest driver can never be sure whether the startup in question is the initial one, a defensive driver will always start with device reet. The question arises because Olivier has posted a series to edk2-devel that adds virtio-mmio support to TianoCore, and Mark tested it (using OVMF) with a Linux guest and found problems. Namely, OVMF itself can drive the virtio devices via virtio-mmio, but the Linux kernel booted from OVMF can not. The reason is the missing zeroing of QueuePFN when OVMF is exiting. (I'm just paraphrasing the analysis.) I...

Hello, is there a way to start a efi-application (bios update tool) from syslinux ? best regards Johann

Hi, I'm pleased to announce release 0.8 of efilinux, a reference implementation of a minimal UEFI bootloader. This bootloader has no bells or whistles, it is simply a prototype with the minimum amount of smarts required to load a linux kernel (though loaders for other formats could be added). Currently it only supports booting x86-64 bzImages but i386 support is planned for release 0.9, with

...target) to create UEFI applications? I need support both PE/COFF and ELF format tools. I’m also working on the lld-link enabling (clang-cl + lld-link) in both Linux and windows. The ld.lld enabling (clang + ld.lld) is for ELF format native users. E.g. https://ci.linaro.org/view/leg-ci/job/leg-virt-tianocore-edk2-upstream/configure. Uefi firmware have many open source developers who like ELF format toolchains … Yes, Uefi firmware application/driver are PE/COFF format. So for ELF format object file, we have a tool to convert ELF to COFF: https://github.com/tianocore/edk2/tree/master/BaseTools/Source/...

Hi all, I noticed that upstream UEFI is now supported ARMv8 on FastModel. I’ve tried it to boot Linux with it. And it works. But it seems it still cannot load Xen hypervisor properly. I’m now looking for the reasons. Is there any difference for a firmware to load Xen and Linux kernel? Cheers, Baozi

...rom fedora's lorax package to see how this was generated. I have a customized copy which generates the macboot.img without the shim support. After you've done generating the iso image with xorriso you can just run: isohybrid --uefi --mac image.iso then test this image with qemu and http://tianocore.sourceforge.net/wiki/OVMF with the -bios option to qemu.
