[gem5-users] Re: syscall newfstatat (#262) unimplemented
The standard library you're linking against is newer, and is using a system call that gem5 doesn't implement. You'll either need to use an older standard library, or implement that system call. If you're trying to run gem5's tests, then I know at least one of the x86 ones uses dynamic linking and links against libraries on your host system (!) which can include calls to the more recent system call. It really shouldn't do that in my opinion, but that's the way it's set up today unfortunately.

[gem5-users] Re: Problem with SIMD instructions execution in se mode when ISA is ARM
Hello Giacomo, Thanks for your reply. I understand what you mean is that if I rename fp operations, it will need to rename the single/double precision operand, and in gem5 we use elements of SIMD vector registers to do this kind of rename. But I still get confused why we use the elements of SIMD registers rather than float registers to do this. In configs/common/cores/arm/03_ARM_v7a.py, I saw we set the number of physical float registers to be 192. Using rename debug-flag, it seems that we didn't use physical float registers during the fp operations. Because in my opinion, in ARM ISA, only we use neon/sve extension, the instruction will have vector register identifier and it can notice the processor we need the vector registers to do vector operations.

Hi, I think while building gem5, I may have missed something. And I didn't realize it during testing the `hello` binary. Now, whenever any binary uses file operations (like `fopen`) then I get the following error: ``` build/X86/sim/syscall_emul.cc:66: fatal: syscall newfstatat (#262) unimplemented. ``` Can someone point me to where could the issue be?

[gem5-users] Re: Issue: Checkpoint in FS mode
Hi Pedro, Thanks for taking the time to reply. You're right. The implementation was missing in my own python script. After including that, I am able to generate the checkpoint. Thanks & Regards Sindhuja -Original Message- From: Pedro Becker via gem5-users Sent: Thursday, September 2, 2021 3:57 AM To: gem5-users@gem5.org Cc: Pedro Becker Subject: [gem5-users] Re: Issue: Checkpoint in FS mode Hi Sindhuja, Are you using your own python script to configure the simulation? If I'm not mistaken calling the /sbin/m5 checkpoint exits the m5.simulate() (from the script), returning the exit_event (a string "checkpoint"). Then, your python script should capture that exit_event and create the checkpoint. This is done in the default scripts (e.g., fs.py/Simulation.py) with something like this: exit_event = m5.simulate() exit_cause = exit_event.getCause() while exit_event == "checkpoint": m5.checkpoint(joinpath(cptdir, "cpt.%d")) exit_event = m5.simulate() exit_cause = exit_event.getCause() But if you have your own python script, then you have to implement this behavior yourself.

Hello, It should be X86 (capitol X) instead of x86. You can see the files in gem5/build_opts for the different possibilities for default build variables.
