Subject: [gem5-users] New Gem5-stable version- deadlock error with Garnet Fixed
pipeline X86 FS simulation
The new Gem5 stable version is not supporting fixed pipeline garnet
simulations. The simulation just fails after entering the event queue. I have
tried all the Ruby protocols (MOESI hammer, MESI two level, MESI CMP
directory), still the bug persisted in all protocols. With flexible pipeline
the simulation is working fine. I have attached the command used for executing
Gem5 and the result I got. Kindly let me know how to fix this.
