Re: iPXE isnt able to get link status from my oprom driver, but PXE works.

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

Re: iPXE isnt able to get link status from my oprom driver, but PXE works.

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.

Re: iPXE isnt able to get link status from my oprom driver, but PXE works.

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

iPXE isnt able to get link status from my oprom driver, but PXE works.

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.

EDK2 and building it on windows

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

Re: SPCR / SSDT generation in the DynamicTablesPkg

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

Re: redundant NULL pointer check

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

Re: redundant NULL pointer check

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

Re: redundant NULL pointer check

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

By wenyi,xie · #458 ·

Re: redundant NULL pointer check

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

Re: SPCR / SSDT generation in the DynamicTablesPkg

Yes, that is the issue we are seeing. Our COM acpi node has a different HID NVDA0100 which uses drivers\tty\serial\8250\8250_tegra.c in linux. It also has a _DSD node to expose the configured clock
