Subject: [Qemu-devel] [PATCH v3 0/2] scsi: lsi: break infinite loop after 10k instructions
Date: Fri, 9 Aug 2019 12:08:33 +0530 [thread overview]
Message-ID: <20190809063835.6717-1-ppandit@redhat.com> (raw)
From: Prasad J Pandit <pjp@fedoraproject.org>
Hello,
While executing script, the LSI SCSI Adapter emulator could run into an
infinite loop, if next instruction read by 's->dsp' index has an empty
opcode. Raise an illegal instruction interrupt and exit the loop after
10k iterations.
-> https://lists.gnu.org/archive/html/qemu-devel/2019-08/msg01427.html
Thank you.
