[gem5-users] Re: Error Parsing cpuinfo in SE Mode
Hi I tried out a few trivial sets of examples on gem5 as per your suggestion. 1. I used the CPP file handling to read the /sys/devices/system/cpu/possible and print the content. This gave an output of 0-1 which is right since I was using a 2 core gem5 configuration. 2. I used the system function to "cat" the contents of the same file in this program. It failed. Gave an abort and gave the following error: warn: ignoring syscall mprotect(...) warn: ignoring syscall mprotect(...) warn: ignoring syscall mprotect(...) warn: ignoring syscall rt_sigaction(...) warn: ignoring syscall rt_sigaction(...) warn: ignoring syscall rt_sigprocmask(...) (further warnings will be suppressed) warn: PowerState: Already in the requested power state, request ignored warn: User mode does not have SPSR warn: User mode does not have SPSR panic: panic condition !handled occurred: Page table fault when accessing virtual address 0x3fffbb1e80 Memory Usage: 8553040 KBytes Program aborted at tick 1061222000 I suppose SE is not supporting such calls ? ___ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an email to gem5-users-le...@gem5.org %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s
[gem5-users] Error Parsing cpuinfo in SE Mode
Hi I am trying to run a TensorflowLite CPP application on gem5-ARM. I see that the application runs perfectly fine when I run it on a native ARM machine. However, its not the case when I try running it through gem5 SE run. I get the following error: Error in cpuinfo: failed to parse the list of possible processors in /sys/devices/system/cpu/possible Error in cpuinfo: failed to parse the list of present processors in /sys/devices/system/cpu/present Error in cpuinfo: failed to parse both lists of possible and present processors It's a very simple program consisting of a model with just one simple FCN layer. I am supposing it's because I am trying to run it using SE Mode. If that's the case how can one run such TF applications on gem5, because I see that most ML applications try parsing the cpuinfo (I might be wrong)? Could anyone please help me with this issue? I am also open to suggestions that are concerned with running different TF/Pytorch etc ML CPP applications on gem5. Thanks in advance! ___ gem5-users mailing list -- gem5-users@gem5.org To unsubscribe send an email to gem5-users-le...@gem5.org %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s
[gem5-users] Vector Instructions Support
Hi I am working on understanding VPUs and vector instructions, and am a bit new to the gem5 environment. I aI wanted to know if there is any official update on the vector instruction support for gem5 x86 and ARM? I see there are some forked versions available in the community but I am skeptical about their stability and version. Would like to know if anyone recommends any such version. I also see In this link https://www.gem5.org/documentation/general_docs/architecture_support/ that gem5 has support for SSE in x86 but see little documentation regarding that. Also no mention of ARM vector instruction support. Sorry if I am wrong regarding the things I have mentioned. So any guidance, help, or advice regarding this will be great!!
