Hi all,
I’m trying to get DRI working with Beignet on a FreeBSD server with Xeon E3-1275 v5 on a Supermicro X11SSZ-F-O Motherboard The motherboard comes with a separate onboard VGA display through an ASpeed 2400 BMC controller.

It looks like the PCI device for the Skylake GPU is missing when I run pciconf:

I believe it should be available in address @pci0:2:0:0: but nothing is there.
kldstat shows the extra Intel GPU modules are loaded:
# kldstat
Id Refs Address Size Name
1 10 0xffffffff80200000 179ddb0 kernel
2 1 0xffffffff8199e000 d7b0 i915.ko
3 2 0xffffffff819ac000 25f08 drm.ko
4 1 0xffffffff81a11000 358e ums.ko
The motherboard BIOS has the onboard GPU enabled. But, I am connecting the monitor for now through the ASPEED controller, not the Intel display. I’d like the Intel display to remain unconnected, as a headless server.
Is this a supported configuration? Anyone know why the on-board Intel GPU wouldn’t show up in the PCI devices list? Right now /dev/dri is missing, and the goal is to get that enabled so that I can run OpenCL apps on the server using the Intel GPU.
