With 10.1.0-rc2, trying to boot v6.16-11744-g9c389564fa8e on sifive_u, I get:

[    2.503619] riscv-pmu-sbi: 16 firmware and 18 hardware counters
[    2.503672] riscv-pmu-sbi: Perf sampling/filtering is not supported as sscof 
extension is not available
qemu-system-riscv64: ../hw/sd/ssi-sd.c:160: ssi_sd_transfer: Assertion 
`s->arglen > 0' failed.

This is without trying to boot from it. Oddly enough, booting from SD card
does work.
