So gBS->UnloadImage() is returning EFI_UNSUPPORTED. Per the UEFI Spec that implies that driver did not register an unload function. Unload functions are not required. Thanks, Andrew Fish

Not sure what should be mising at this point; the DEC default for PcdPciBusHotplugDeviceSupport is TRUE. Using OVMF, virtual PCI and PCIe devices can be hot-plugged. (Not sure about NVME, but

Hi All, Does anyone know whether the development status of Pcie Hotplug support using PcdPciBusHotplugDevice is completed (especially with respect to NVME drives)? Has anyone successfully enabled

Thanks Laszlo, clear now :)

Thank You Laszlo

What protocols are being uninstalled, and what driver is being unloaded? If you return an error from your driver it will get unloaded. I don’t understand the combination of gBS->UnloadIMage() and

Notify() is "serviced" in the context of the OS. Correct. The AML interpreter / executor is a part of the OS. AML "runs" because the OS makes it run. The Notify() operation "calls into the OS"

I wouldn't be surprised if this was caused by improper memory management on unload (I actually wrote this kind of Highlander Protocol for the sfc driver). These are the things that I would check: 0.

HI Sandeep, The EsrtDxe provides an API to add ESRT entries manually, you could instrument that in SfcNicDriver actually - during controller binding check if gEsrtManagementProtocolGuid is installed

This is certainly the right mailing list to ask on; sorry about the delay (I didn't get a notification email about your message pending moderation -- but now further messages from you should go

+Andrew: Andrew, do you recall changes related to driver dispatch between 2.3.1 and 2.4? Not necessarily in the spec, but maybe in edk2. Thanks Laszlo

+Igor, some comments below My (rusty) understanding is that hardware signals the OS with "general purpose IO" and/or SCI (ACPI) interrupt. Then the OS invokes General Purpose Event handlers (GPE

Hi Discuss List, I'm *still* not getting moderation requests (notification emails) for edk2-discuss, only edk2-devel. That's the reason some messages to edk2-discuss have been stuck for a few days

Hi Tom, I tried MdeModulePkg/Universal/EsrtFmpDxe, but booting hanged at selecting Boot option. I then used, MdeModulePkg/Universal/EsrtDxe/EsrtDxe.inf. There are no issues observed in boot, but,

Hi all! I would like to ask the community about a way to automatically use HTTP boot in a QEMU VM using OVMF. Currently I can set the network interface to be the first in the boot order, then when

Help please Thanks

I have a couple of ancient branches in various states of disrepair that were used as part of an API tester at one point. It's from before FMP was really driving anything and before the ESRT data

Hi Team, I have developed a UEFI Bus Driver, loaded it as an PCI Option ROM on PCI adapter. Issue I am facing is with the during version updates. In DriverSupported, SW update logic present looks
