Public bug reported: On my SpacemiT K3 I run kernel 7.3.0-9-generic. I start a VM with Ubuntu 26.10 also running 7.3.0-9-generic using KVM. The hwprobe syscall in the VM reports:
Zicclsm NOT supported Ziccamoa NOT supported Ziccif NOT supported Za64rs NOT supported My expectation is that the VM should support full RVA23U64 compliance except for extension H. https://github.com/xypron/hwprobe.git can be used for testing. --- ProblemType: Bug AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Oct 12 21:40 seq crw-rw---- 1 root audio 116, 33 Oct 12 21:40 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' ApportVersion: 2.36.0-0ubuntu1 Architecture: riscv64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CRDA: N/A CasperMD5CheckResult: unknown CloudArchitecture: riscv64 CloudBuildName: server CloudID: nocloud CloudName: unknown CloudPlatform: nocloud CloudSerial: 20261012.1 CloudSubPlatform: seed-dir (/var/lib/cloud/seed/nocloud-net) CurrentDmesg: Error: command ['dmesg'] failed with exit code 1: dmesg: read kernel buffer failed: Operation not permitted DistroRelease: Ubuntu 26.10 Lspci-vt: -[0000:00]-+-00.0 Red Hat, Inc.
