[gem5-users] Re: Using NIC in gem5 with x86 architecture

2023-05-17 Thread Antoine Kaufmann via gem5-users
Hi Varun, for what it's worth, we've been using the Intel e1000/igb NIC in gem5 with regular Linux for a while without problems, I would start there unless you really want the other NIC. We have some working (albeit complicated) full system dist gem5 (for a slightly dated gem5 version) scripts

[gem5-users] cache-coherent numa config with classic memory system

2023-05-15 Thread Antoine Kaufmann via gem5-users
Hi everyone, I am currently trying to build gem5 config with the classic memory/cache system that reasonbly resembles a typical multi-socket x86 numa server, but have so far not been successful. (I know Ruby has much more flexiblity here, but I would also like a config with classic components if

[gem5-users] Modifying simulation structure after instantiation/checkpoint restore

2022-04-12 Thread Antoine Kaufmann via gem5-users
Hi everyone, I have a quick conceptual question about gem5 configuration: are there restrictions about what can be modified in an already instantiated and initialized gem5 config, say after restoring from a checkpoint. I know there is some special cases such as replacing CPUs on restore. Is this

[gem5-users] Working X86 multi-core full system config with caches?

2021-10-28 Thread Antoine Kaufmann via gem5-users
Hi Everyone, Do we have any known-working configurations for x86 multi-core full system simulations with caches? We have successfully been using single core configs for more than a year now, but our attempts at anything multi-core have so far not been successful, with problems ranging from gem5

[gem5-users] PCI operation ordering

2021-05-17 Thread Antoine Kaufmann via gem5-users
Hi, We have been using gem5 with the classic memory system for a while for full system X86 simulations integrating a number of different more modern PCIe device models. Now we are trying to get things to work with Ruby as well for multi-core X86 simulations. Currently we are tracking down some
