Sunny, There are two other public, non-uefi spec solutions I am aware of. 1. Edk2 VariableLock protocol:

Re: Lock BootOrder variable

The UEFI define the BootOrder variable with NV+BS+RT attributes, so its not possible to lock this variable, you can try to delete the BootOrder variable and then set the variable with AT attribute,

Re: [edk2-devel] [PATCH] Support skipping automatic BM enumeration

Thanks for the summary Ray, for the problem summary only thing I would add would be that platform also wants to create/modify boot options when full enumeration is requested as well. For solutions I

Lock BootOrder variable

Hi All, Is there any spec'd way that we can use to lock some UEFI variables like BootOrder without breaking OS installation and OS functionalities? For some security reasons and customer use cases,

Re: [edk2-devel] [PATCH] Support skipping automatic BM enumeration

Jeff, Tom from AMD booked the meeting for SEV discussion months ago. I am afraid there is no time for this discussion. Let's try to resolve it in mails. Firstly, let me rephase the problem and

Hi all, Since I can't attend the design meeting (EMEA), I would like to add some use cases and a suggestion for your guys' reference before this topic being discussed: We had similar needs (use

Re: Problems in running EmulatorPkg.

This seems like an old thread. https://edk2.groups.io/g/devel/topic/30916071 I remember I also saw segmentation fault as well. Disabling optimization works for me. EmulatorPkg.dsc

Re: Examples opening and reading/writing a file with EDK2

Hi Alejadro, I am trying to answer your questions. If anything missed, please feel free to let me know. 1. First I think CapsuleApp is a good example to consume the file protocol. 2. File handle

Re: [OVMF] resource assignment fails for passthrough PCI GPU

(+Jiri, +libvir-list) Yes, and because it affects live migration ability, we have two constraints: 1) It needs to be exposed in the libvirt domain XML; 2) QEMU and libvirt can't choose a value that

Re: [OVMF] resource assignment fails for passthrough PCI GPU

Thanks -- this is a useful piece of the puzzle to know. It seems that the guest can learn about the guest-phys address width via CPUID. (cpu_x86_cpuid() in "target/i386/cpu.c" consumes

Re: Examples opening and reading/writing a file with EDK2

First, you need to find the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL instance in the protocol database that is right for your purposes. You could locate this protocol instance for example with the

Re: [OVMF] resource assignment fails for passthrough PCI GPU

Hi, Yes. You can see it as "address sizes" in /proc/cpuinfo Problem is this isn't reliable in virtual machines. qemu reports 40 bits physical even in case the host supports less. Intel hardware

Re: [OVMF] resource assignment fails for passthrough PCI GPU

Heh, now that you explain this, I *vaguely* recall it from discussions conducted maybe years ago. :) It's just as well that I wrote, in my sibling response, "There could be other QEMU/KVM / libvirt

Re: [OVMF] resource assignment fails for passthrough PCI GPU

(+Dave, +Eduardo) "PCPU address width" is not a "function" of the available physical bits -- it *is* the available physical bits. "PCPU" simply stands for "physical CPU". Maybe. The current logic
