toothe has joined #systemtap
<toothe> odd - when I run sudo stap -L 'kernel.function("*")' nothing is listed.
slowfranklin has joined #systemtap
<toothe> I ran stap-prep
<toothe> do I need to reboot?
<fche> shouldn't.
<fche> did stap-prep suggest anything be done?
<toothe> no. seemed to work just fine.
<fche> which distro are you running?
<toothe> Fedora
<fche> ok great ... so what does rpm -q kernel kernel-debuginfo say?
slowfranklin has left #systemtap [#systemtap]
<fche> or sh -x stap-prep for that matter :
<toothe> err, I'm sorry - give me a moment.
<toothe> first command
<toothe> oh wait ,the latter part of the 2nd dpaste?
<fche> ok, and what kernel are you running?
<fche> hm there's definitely a 'need to install ...' in there :)
orivej has quit [Remote host closed the connection]
<toothe> im sorry!
<toothe> 4.13.10-200.fc26.x86_64
<toothe> that's what I am on.
<toothe> Someone came up and was speaking to me - freer now.
<fche> yeah. so stap-prep's advice is the correct one:
<fche> Need to install the following packages:
<fche> kernel-debuginfo-4.13.10-200.fc26.x86_64
<toothe> I ran stap-prep earlier. Is there a way to install it?
<fche> if you run stap-prep as root, it'll try to do it for you
<toothe> just did again...oh, problem
<toothe> problem installing rpm(s) kernel-debuginfo-4.13.10-200.fc26.x86_64
<fche> if yum can't get it for you, you can get it off of koji (^drsmith, fyi)
<toothe> what seemed to go wrong?
<fche> not sure, was there a message other than 'problem installing rpm(s) ...' ?
<toothe> wow, I have a super good connection or I"m really closer to the datacenter.
<toothe> no, that's it...
<toothe> while it DLs, I just want to thank you for writing this.
<toothe> like I said earlier, I switched from Ubuntu for this.
<fche> hey, no problem, a lot of people worked on it
<fche> and it should work ok on Ubuntu too -- just that they make debuginfo a little harder than here in fedora land
<toothe> well, i didn't even get it compiling those modules.
<toothe> there was a function that i've seen crap out elesehwere, set_page_something
<fche> anyway - is that download working ok? have the needed debuginfo now?
<toothe> its downloading, its fairly large.
<toothe> heh, it actually just terminalted the DL, but wget restarted it in place.
orivej has joined #systemtap
<toothe> alright, now getting the common symbols.
<toothe> much faster.
<fche> perfecto
<toothe> i might want to delete the other symbols.
<toothe> or rather, packages.
<toothe> for older kernels and suhc.
<fche> we're cooking some software that might moot all this installation work, but not ready yet
<toothe> yes, that'd be nice.
<fche> plus - syscall.* probes or kprobe("function") ones don't need debuginfo
<toothe> is this widely used by people in production systems?
<fche> see [man stapprobes]
<toothe> ive even wondered how widely used dtrace is.
<fche> dunno about 'widely' - it's not like we have a running-software census :)
<fche> we have certainly had some high-profile uses
<toothe> like by some guy named toothe? :)
<toothe> who loves it?
<toothe> and there it goes! gave me the symbols.
<toothe> awesome.
<toothe> thanks man!
<fche> glad to be of help
<fche> let us know if you have some neat use stories
<toothe> I can tell you now, i guess
<toothe> I'm writing a FreeBSD device driver.
<toothe> so, I need to figure out how it works in real-time.
<toothe> I bought antoher and slapped it on my Linux personal machine, (even though its a PCIe card, had a converter)
<toothe> and then I have a FreeBSD laptop where I run FreeBSD.
<toothe> so I compare the two drivers and am making a FreeBSD port.
<toothe> systemtap is helping me figure out wtf is giong on.
<fche> aha, so porting over a linux driver more or less?
<toothe> yes.
<toothe> rtlwifi/rtl8188ee on Linux
<toothe> rtwn on FreeBSD
<fche> aha. yeah, tracing the details of execution is great when trying to figure out how things work
<fche> have you seen varwatch.stp ?
<toothe> no?
<fche> all these show off how statement-level (line-by-line) tracing can be useful
<toothe> i don't get what this does yet?
<toothe> i have it open.
<toothe> ahhh, the actual arguments!
<toothe> i can see myself using this.
