Hi,
So an update on a potential demo platform for the AGL demo.
Platform:
MACCHIATObin 1.2 board + manually applied PCIe reset fix + removed JTAG & hacked PCIe + NVIDIA GK208B (originally from SynQaucer) + EFI firmware on sdcard from Steve McIntyre
I have a fairly stable box running Debian Buster + backported kernel + testing Grub (for Xen) with managed graphics (via nouveau) and working sound (via a USB audio dongle). With the following caveats:
I use the DT system info instead of ACPI.
I keep hitting ESC on serial at boot prompt and selecting "Reset" until the graphics card wakes up and displays EFI splash screen on the monitor.
and
Only kernel 5.6.0-0.bpo.2-arm64 #1 SMP Debian 5.6.14-2~bpo10+1 (2020-06-09)
While I can get a newer kernel to build and boot up the graphics either comes up corrupted or keeps crashing the X server with a kernel related nouvaue bug. I've tried to narrow it down but both vanilla 5.6.0 and 5.6.14 have the same problem so I suspect there is a patch in the Debian series which fixes it which might need up-streaming.
(aside: anyone know how to make a traditional bisectable git tree from a series of Debian patches?)
KVM works and I'm able to boot up my test kernel and get to a userspace prompt on the serial console. I still have to boot up with virtio-gpu and prove that works.
I've been unable to get Xen up and running on it so far. I've tested with vanilla and also the current testing tree that I finally got working on QEMU TCG. I have gotten some Xen diagnostics which I've dumped into a separate thread so as not to confuse things too much.
