Subject: [PATCH 0/2] target/arm: fix for hvf regression in v10.2-rc1 (#3228)
Date: Fri,  5 Dec 2025 15:11:13 +0000	[thread overview]
Message-ID: <20251205151115.2035930-1-alex.bennee@linaro.org> (raw)

Although bisecting indicated 93ac765076a (target/arm/hvf: Keep calling
hv_vcpu_run() in loop) was the culprit I noticed that using gdbstub
would get further in the run due to the enforced syncing from being
debugged.

As far as I can tell the kernel got confused by contradictory responses
from PSCI while booting up and then never recovered.

Please test.

Alex
