Sorry for the formatting mess in my previous email, my mail client
stripped the linebreaks. Here is the readable version:

Tested on POWER10 (native KVM, ppc64le).
Tested-by: Aniket Sahu <[email protected]>
--- Environment ---
Host CPU : POWER10 (architected), altivec supported
Kernel : Linux 7.0.0-27-generic #27-Ubuntu SMP PREEMPT_DYNAMIC
Thu Jun 18 19:14:19 UTC 2026 ppc64le GNU/Linux
OS : Ubuntu 26.04 LTS (Resolute Raccoon)
QEMU : 10.2.1 (Debian 1:10.2.1+ds-1ubuntu3.1)
Accelerator: KVM (-accel kvm -machine pseries,cap-ccf-assist=off)
Branch : origin/ppc64 @ dde8f397
--- Test: pmu (Patch 1) ---
$ ./run_tests.sh -a powerpc pmu
PASS pmu (22 tests, 1 known failure)

PASS: pmu: bhrb: correct conditional branch address
SUMMARY: 22 tests, 1 known failure
EXIT: STATUS=1
Note: The KFAIL on "BHRB has written 8 entries" is expected. POWER10
records 4 BHRB entries when other threads are active on the core; the
test explicitly accounts for this with a fallback 4-entry check which
passes. STATUS=1 is the correct exit code when known failures exist.
--- Test: selftest-setup (Patch 3/build structure) ---

PASS selftest-setup (2 tests)

--- Test: selftest-panic (Patches 5 & 6) ---

-smp 1 -append panic
qemu-system-ppc64: OS terminated: rtas_os_panic
PASS: guest panicked
EXIT: STATUS=1
Note: The panic test validates both the new rtas_os_panic() RTAS call
(Patch 6) and the run_panic() exit status fix (Patch 5). QEMU exits
with "OS terminated: rtas_os_panic" confirming the ibm,os-term RTAS
token is correctly invoked, and the test runner correctly identifies
this as a successful (expected) panic.
