Hello!

Small update on this..

The goal i want to achieve is to have a GPU passthrough on OI to a 
Windows vm with bhyve...

I now tested linux/proxmox (kvm)  and FreeBSD 14 (bhyve) with success, 
so i can assume the Hardware and the BIOS settings are ok.

FreeBSD has this version of the edk2 image:

$ pkg search edk2
edk2-bhyve-g202308_4           EDK2 Firmware for bhyve

.. so version 202311 seems not to be needed (?)

What i see if i try it on OI, is that

immu-intrmap-enable="true";

in

/platform/i86pc/kernel/drv/rootnex.conf

leads to error messages when i start the bhyve test script with messages
APIC ERROR Interrupt on CPU 0. Status 0 = 0 Status 1 = 40.
on the console and the system is not responsive anymore..


Do i _need_ immu-intrmap-enable="true"; ?


I currently have these values set:

immu-enable="true";
#immu-intrmap-enable="true";
immu-blacklist=
                 "SMBIOS","Supermicro","X10DRI-T",""
                 ;
immu-dvma-mapping="xlate";
immu-dvma-unity-drivers="igb","ahci","ixgbe","ehci","xhci","nvme";
immu-dvma-xlate-drivers="mpt";

Is anyone around with a success story who has been there and done that ?


i want to passtrough this:

$ pptadm list -o all

Advanced Micro Devices, Inc. [AMD/ATI] Navi 21/23 HDMI/DP Audio Controller

... using this test script:

$ /usr/sbin/bhyve -U bd60bf59-0ed6-61a1-f0ed-b17e99ada165 -A -H \
-B 
1,manufacturer=OpenIndiana,product=OpenIndianaHVM,version=1.0,serial=69a18a85-c1df-c266-f620-a99a632d3c11,sku=001,family=VirtualMachine

-S -s 8:0,passthru,/dev/ppt0,rom=/home2/vm/Navi24.rom \
-s 8:1,passthru,/dev/ppt1 \
win10

The GPU can be seen within the vm (error 43), it seems the card doesn't 
get initialized..

Any hints are welcome..
