My understanding of ARM secondary core startup is that the stacks for all the cores live at the top of UEFI memory. The secondary core stacks sit at the top, with the primary core stack just under

I did a quick look in edk2-platforms, and found similar cases at least with a couple of other systems: Marvell Armada and OctenTx. Both of these use a _HID of "MRVL0001" (with its own clock-frequency

Hey I have your firmware installed in my aser Chromebooks bios files, and I'm not quite sure if I need it for my destro to boot through and run the desktop I want. But I'm just confused as to what

This shows that you are using iPXE's "NII" driver, which uses the UEFI UNDI API. (Possible alternatives were the "SNP" driver which uses the UEFI SNP API, or a native PCI driver.) The link is

Hi Michael, I am unable to break into iPXE shell (using Ctrl+B). I could capture the below log from the serial console. >Checking Media Presence...... >>Media Present...... >>Start PXE over IPv4.

Thanks for the heads-up! Udai: which driver is iPXE using? You can find out via the "ifstat" command in the iPXE shell. Thanks, Michael

Hello Community, My OptionRom driver works with PXE but it fails to get/report link status in iPXE. I had setup iPXE.efi in dhcp.conf to load it from DHCP-PXE server. I see it gets loaded properly.

Hi, no clue, but I'm adding Michael. Thanks Laszlo

There is some training material here: https://github.com/tianocore-training/Tianocore_Training_Contents/wiki. If you look at BaseTools/Conf/tools_def.template you will see "Supported Tool Chains",

Hello, I work on a UEFI project with Visual Studio 2019. When I first learnt that I can directly control computer with UEFI I was really excited. I got a sample project called GNU-EFI from osdev.org

Good day, I have been setting up a sort of TPM2 developer environment with QEMU and OVMF, and have hit a snag (https://bugzilla.tianocore.org/show_bug.cgi?id=3106). In short, I can build OVMF and

Hi edk2 guys, I have a question about BootOrder recovery behavior and want to consult with you. I found Boot0000 would be first place in BootOrder when system try to recover options. Please check

Hi all, Recently, I am studying a new feature that need to use camera in UEFI BIOS. And I found that EDK2 do not support isochronous transfer. (please refer to attached) But almost all webcams only

Hi Irene, Jeff, If I understand correctly, when the HID is PNP0501 the Linux driver ‘drivers\tty\serial\8250\8250_pnp.c’ is setting ‘uart.port.iotype = UPIO_MEM;’ This results in the

Hi Laszlo, Thank you for your detailed explanation, I get it. I will post a patch later. Thanks Wenyi

Well, we can approach this on two levels. The first level is whether the code transformation (the patch) that you are describing above would be correct. Yes, removing the comparison in question is

Hi Laszlo, So if (Info->VolumeLabel == NULL) will always evaluate to FALSE when Info != NULL. Can we just remove it. Thanks Wenyi

Assuming Info is a valid pointer, Info->VolumeLabel is an array object. When evaluated, Info->VolumeLabel is converted to the address of its first element. The address of the first element of an

Hi all， When removing -Wno-tautological-compare, there's a warning. MdeModulePkg/Library/FileExplorerLib/FileExplorer.c:850:19: warning: comparison of array 'Info->VolumeLabel' equal to a null
