This was working a few days ago but I updated my OS and some libraries along with it. Glibc, gcc, xorg, etc.

I tried running uProf 4.0.341 and it does not attach to processes - "the driver failed to start profiling. (error code 0x80004005)"

Hello,

Can you explain the issue in more details so that I could reproduce this on my machine here?

[feliwir]

I'm facing the same issue on Fedora 37 with Linux:

"ERROR : The driver failed to start profiling. (error code 0x80004005)"

[santosh_zanjurne]

Hi, I tried reproducing this on our end here but could not.  Can you please elaborate more on what exactly you are doing...  that would help us reproduce the issue and help you use uProf successfully?

I'm facing the same issue on Fedora Silverblue 37. Any process I attach to or start profiling from uprof give me "The driver failed to start profiling. (error code 0x80004005)" screen. Same problem runnning sudo.

AMDuProf_Linux_x64_4.0.341.tar.bz2

Linux fedora37.fedora 6.0.15-300.fc37.x86_64

[santosh_zanjurne]

Can you share the output of below command:

AMDuProfCLI.exe info --system

[feliwir]

This just gives the following error:

[stephan@fedora bin]$ ./AMDuProfCLI --system
ERROR: Invalid option or missing command.

Please note that executables on linux don't have an ".exe" extension

Thanks for the info.  I am working on to reproduce this issue. I will keep you posted on this.

[santosh_zanjurne]

I could not find the build you used, but i could not reproduce the issue with Rawhide.20230112.n.0 (Silverblue Prerelease)-64.  Let me know if can test this or any other build which we both can use.

[feliwir]

This just happens for the regular latest stable linux release of AMDuProf (AMDuProf_Linux_x64_4.0.341). Just go the downloads section😅

[santosh_zanjurne]

I tried to reproduce the problem you reported with latest fedora build, build i could not reproduce it.  I tried below build.

Can you try the latest build of Fedora and see if you still see the issue?

[feliwir]

I don't know which Fedora you have installed. It should just show something like "LinuxFedora Linux 37":

[santosh_zanjurne]

Hi, I think I have reproduced the issue - i will keep you posted on this work here.  Can you try to profile the application in the same terminal as your application is running?

[santosh_zanjurne]

Hi, I could not reproduce the issue you reported.  Do you think we can meet online and discuss the issue?  drop an email to toolchainsuppot at amd dot com and we shall work together to understand/resolve the issue.

[meisme-dev]

I can reproduce this in Fedora 37 using the latest RPM
