Various problems trying to vga-passthrough a Renoir iGPU to a xen/qubes-os hvm

Hello,
Xen passthrough of a boot GPU those days (at least in the small QubesOS world)
is mostly tested/documented for Intel iGPUs (or I missed something).
I've been trying to do that with a Renoir GPU (for context, the goal is
to have a xen domU dedicated to the GUI [3]). I won't go into all the details
of my successive attempts in this email, various (relative) progress reports are
available at [0] (there are other things to be investigated listed there, but
at least some of them can possibly wait). And I have surely missed more than
a couple of key points.
Summary of the setup:
- GPU protected from dom0 driver using pci-stub (gets access to the GPU via efifb
until hopefully the GUI domain seizes it)
- host is Xen 4.14, dom0 uses Linux 5.14 (Qubes' kernel-latest)
- guest is a Xen HVM with running in a stub domain, launched through libvirt/libxl
- hackish enablement of the IGD passthrough codepaths through
- libxl PCI VID hack: https://github.com/ydirson/xen/commit/4c9d4cb5c3dc1282ba83f17d15072c197b60281c
- qemu BDF hack: https://github.com/ydirson/qemu/commit/6a165467e25864f1ae17390a44a9c1425ba67aed
The first problem encountered, i.e. that the guest amdgpu driver was not able
to access the PCI expansion ROM, I have hacked around for now by letting the
driver load as firmware a copy of the ROMdriver [1] - this was a 5.14.15 kernel
with the QubesOS patches (all reachable from this commit).
Doing this seems to make the driver happy on this aspect, but several issues
now become visible, and after some digging I feel some insights from people
familiar with the code gets really necessary :)
The first problems are shown below as [T0], my interpretation being:
1. Xorg aborts (audit: type=1701) -- should find a way to get more details, but
that is surely not the root cause of what follows
2. a PSP command fails -- I cannot find any AMD documentation on how PSP works,
that could possibly help
3. the PSP fails to load some firmware as part of its own init -- here I'm quite
uncomfortable, I thought of the PSP as being distinct from the cpu cores and
gpu, but here it appears as a disting IP *within* the gpu. I also failed to
find any detailed description of the whole stuff and their interactions.
4. following this failure the driver finishes (while initialization was still
ongoing)
5. then vcn_v2_0_sw_fini() triggers a bad memory access, which appeared to be
while dereferencing adev->vcn.inst->fw_shared_cpu_addr.
After adding traces on the individual IPs init/fini [2] showed that the vcn
sw_init was indeed run, and likely initialized this pointer. Any idea how
it became invalid ? One track I briefly followed was that some of the IP
init appears to be asynchronous (the failure in PSP init occurs after later
IPs get initialized), but that pointer seems to be initialized early and
synchronously by VCN sw_init.
Then, to workaround the problem with PSP not being able to initialized, I used
fw_load_type=0 to use direct loading (and noted that fw_load_type=1, advertised
as loading firmware using SMU, just does not do anything in the code).
The result, using 5.15.4 at this time, resulted in trace [T1]. The error surfacing
now is "ring kiq_2.1.0 test failed" with a timeout. I had to dig the kernel commit
messages to discover that KIQ is a Kernel Interface Queue, and there are various
other acronyms around this (eg. "eop", whose introduction seems older than the
landing of the driver in the kernel) which really make it hard to be efficient at
understanding the code. Will gladly be enlightened :)
And this also ends with the VCN sw_fini going fireworks, and a quick look at the
assembler seems to hint that although the code changed a bit, it is still the
same statement crashing.
Also noticed that ip_block_mask=0xfff7 to disable the PSP on this ASIC will do slightly
different things, but end up with the same errors.
I will gladly take any suggestion, pointers to additional information, etc :)
Best regards,
