Subject: [Qemu-devel] [PATCH v3 0/2] scsi: lsi: break infinite loop after 10k instructions
Date: Fri, 9 Aug 2019 12:08:33 +0530

From: Prasad J Pandit <address@hidden>


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.

Thank you.
