Subject: [Qemu-devel] [arm] Integrator/CP regression under QEMU 2.1.0 running HelenOS
Date: Tue, 19 Aug 2014 15:01:32 +0200 [thread overview]
Message-ID: <53F34AAC.4030905@jermar.eu> (raw)
Hello,
there seems to be a regression in QEMU 2.1.0 which demonstrates itself
when running the mainline HelenOS Integrator/CP (i.e. ARMv5) image. The
offending instruction seems to be:
vmrs r0, fpsid
Upon its execution, HelenOS kernel receives an Undefined instruction
exception (which it does not anticipate at that point) and crashes.
QEMU 2.0.0 was not affected by this issue.
Any ideas what may have gone wrong? If needed, I can provide a test binary.
Please Cc me directly in your reply as I am not subscribed to qemu-devel@
Thanks,
Jakub
