...tree? Can we hold on a tiny bit so that I can verify we haven't regressed crosvm all the way into mainline? Daniel, is there any chance you could test with kvmtool as well on your setup? You can easily compile it as a static binary and run it from ChromeOS with: lkvm-static run -c 1 -p "earlycon=uart,mmio,0x3f8" -l Image which should start a UP guest and drop you to a shell. In the meantime, I'm starting to build crosvm on my kevin running mainline. Thanks, M. -- Jazz is not dead, it just smell funny.

Hello, In my testing of crosvm[1] with Linux 4.4.175, I am observing failures on a 'kevin' Chromebook (RK3399) device - the guest kernel does not even get to the point of printing its first messages, and the host seems to be spinning at 100% CPU in KVM_RUN. I narrowed this down to the 4.4 stable backport of "arm64: KVM: Skip MMIO insn after emulation" - with this patch

Hi to all. I'm experimenting with running a https://www.zotac.com/us/product/graphics_card/geforce%C2%AE-gt-710-1gb-pcie-x-1 card on an Nvidia Jetson TX2 arm64 device. Possible? Linux kernel aarch64 5.6.10. Because Nvidia did not list drivers for this architecture, I'm experimenting with a nouveau driver. The Jetson TX2 has a default driver for the host1x framebuffer for output from the
