<br>
Yes. I can detect my pci device (UEFI 'pci' command), and load the
driver. On a real UEFI machine I can successfully PXE boot.<br>
<br>
I am not sure if that makes a difference with your command I see
in the screenshot, but I use a command like <br>
fs0:\> load <driver name>.efidrv<br>
to load the driver. Not a simple invocation of a *.efi file.<br>
From what I mentioned in my previous email yours may be:<br>
ipxe/src $ ls bin-x86_64-efi/*.efidrv<br>
bin-x86_64-efi/82579lm.efidrv<br>
Check the output of 'pci' in your UEFI shell (see previous email).<br>

If the steps I described previously don't work you may try to
better undestrand why EFI_UNSUPPORTED is returned. Check the

I don't really understand the question here. You can compile a

<div class="moz-cite-prefix">My patch will potentially fix
some errors reported by <a moz-do-not-send="true" href="http://www.uefi.org/specs/">SCT</a>. It probably
won't fix your problem.<br>
<br>
I have little experience with UEFI or iPXE, but here are a
few suggestions:<br>
<br>
The commands you listed don't work for me, and I could not
find matching vendor / device id for the first 3 devices
you mention:<br>
$ cd <ipxe_repo>/src/<br>
$ grep -RHIin 8086 drivers/net/ | grep -i 2000<br>
$ grep -RHIin 8086 drivers/net/ | grep -i 2001<br>
$ grep -RHIin 8086 drivers/net/ | grep -i 2625<br>
<br>
I could build a efi-driver for the last device your
mention:<br>
<br>
Commands:<br>
$ cd <ipxe_repo>/src/<br>
$ grep -RHIin 8086 drivers/net/ | grep -i 1502<br>
gives me:<br>
./intel.c:926: PCI_ROM ( 0x8086, 0x1502, "82579lm",
"82579LM", 0 )<br>
<br>
So I could build your UEFI driver with the command:<br>
$ make bin-x86_64-efi/82579lm.efidrv -j6<br>
(replace efidrv with efirom to build a rom)<br>
<br>
<br>
I am wondering if your other devices are supported. Maybe
the way I am looking for devices is not appropriate
though.<br>
<br>
Here is an example procedure to load the driver built
previously (very verbose).<br>
<br>
cd to the filesystem<br>
> fs0:<br>
Check that your device exist. Here look for your device
0x8086, 0x1502<br>
> pci<br>
Check what drivers are loaded. Write down the index of the
last driver loaded.<br>
> drivers<br>
List devices. Write down the index of the last device<br>
> devices<br>
Load your driver manually (this is the file compiled
previously)<br>
> load driver\82579lm.efidrv<br>
Now check if your driver is loaded<br>
> drivers<br>
and if your device is present.<br>
> devices<br>
<br>
If that does not work maybe try to enable debug in some
iPXE files.<br>
For example:<br>
make bin-x86_64-efi/82579lm.efidrv -j6
DEBUG=intel,efi_snp,efi_init<br>
Enabling debug in files related to your device may give
you some useful info.<br>
<br>
Hope this helps,<br>
<br>

<div><b>Subject: </b> [ipxe-devel] UEFI SCT patch</div>
</div>
<div><br>
</div>
Hello,<br>
<br>
I recently started working on our UEFI driver, and some
of my changes <br>
may be useful for iPXE upstream.<br>
<br>
So here is a first patch dealing with NIC independent
code. Can you have <br>
a look and let me know if it needs some modifications.<br>
It includes:<br>
- changes to be more UEFI compliant and pass SCT tests
(most changes <br>
in efi_snp.c)<br>
- initial support for the driver health protocol<br>
- initial support for the firmware management protocol<br>
<br>
You'll probably want to verify the additional checks for
UEFI versions:<br>
- I added the DRIVER_EFI_SUPPORTED_VERSION protocol,
as required by <br>
the UEFI spec.<br>
" Provides information about the version of the EFI
specification that a <br>
driver is following. This<br>
protocol is required for EFI drivers that are on PCI and
other plug in <br>
cards. "<br>
- In efi_init.c I added a check for a minimal version of
UEFI required <br>
to use the driver. I am not sure you want to keep that.<br>
<br>
<br>
