Hello,
Happy New Year!
I'm facing a hart isolation configuration error when running OpenSBI
1.8 on QEMU 10.1.3 with the RISC-V application profiles rva22s64 and
rva23s64:
init_coldboot: hart isolation configure failed (error -3)
No issue occurs when using the rv64 profile. The system continues to
boot after the error, but I'd like to understand the root cause.
I haven't tested OpenSBI 1.8 on real hardware yet - that's my next
step.
Is there a known QEMU issue? Is there a recommended workaround besides
using rv64?
Below is the complete trace:

I had tested on real SiFive Unleashed and StarFive VisionFive 2 board
along with QEMU virt machine and QEMU sifive_u machine.
On QEMU virt, I had only tested rv64 and max CPU types which
worked fine. I guess I should include rva22s64 and rva23s64
CPU types in my testing as well.

Yes, I was able to reproduce this failure on the latest
QEMU virt machine with rva22s64 CPU type.

Thinking about this more, this looks like QEMU bug because
there are no PMP entries for rva22s64 and rva23s64 which
is why there is no hart isolation mechanism hence the hart
isolation configure fails.

QEMU disables PMP by default; the following option needs to be added.
-cpu rva23s64,pmp=true

Thank you. With the additional option, the issue no longer occurs.

I have done an incremental OpenSBI v1.8.1 release
to address this issue. With this incremental release,
you don't have to explicitly pass "pmp=true" to
rva22s64 and rva23s64 CPU types in QEMU.

Anup

Seems like we don't need this patch I sent a few days ago then:
"[PATCH] target/riscv/cpu.c: enable PMP by default for profile CPUs"
https://lore.kernel.org/qemu-devel/20260106205152.3654975-1-daniel.barboza@oss.qualcomm.com/
We can leave this patch alone. We can also leave the update to OpenSBI
1.8 alone as well and update to 1.8.1 to get the fix.
Thanks,
Daniel

I think the QEMU patch is still needed because without PMP
there is nothing to protect M-mode firmware (OpenSBI) from
lower privilege modes.
