Re: [gem5-users] building gem5 simulator in full_system mode.

2014-05-22 Thread Steve Reinhardt via gem5-users
The simulator no longer needs to be compiled in full-system or system-call emulation mode; the same binary now supports both. Wherever you read about compiling in full-system mode is out of date. Steve On Thu, May 22, 2014 at 10:58 PM, Ravi Verma via gem5-users < gem5-users@gem5.org> wrote: >

Re: [gem5-users] How to build a newer linux kernel for gem5

2014-05-22 Thread Fernando Endo via gem5-users
Hello, The message "kernel too old" usually appears when the toolchain you're using embed linux headers newer than the version of your kernel. Are you using the native gcc in the gem5's disk image (the new one)? I had no major problems to compile PARSEC 3.0. There were only a few dependencies to

Hi Menglong, 1. The memory type should not have any impact here. 2. I suspect you are running in atomic mode, and thus the DRAM timing model is never used. Hope that helps. Andreas From: Menglong Guan via gem5-users mailto:gem5-users@gem5.org>> Reply-To: Menglong Guan mailto:menglong.g..
