i'm having problems with the patch. beforehand, playing music from www.mixcloud.com worked. now the flash based player is initialising forever.
just drop me a note with exact instructions and i can give you more verbose information or debugging stats. again: this issue might be futex related and not a result of your patch.
Are you running -current? If yes I Looks try to get some time to commit the linuxulator-dtrace probes, now that SDT probes can be loaded dynamically there is no risk to panic the system when the linuxulator is loaded after boot and dtrace is used. This could help looking at problems with locks.
yes i'm running a very recent HEAD on amd64.
I'm in the process of merging all the new stuff from HEAD into my SVN branch. With a slow system and a slow line this may take a while. I hope to at least update my branch in SVN (users/netchild/linuxulator-dtrace) today. I don't know if I get the time to merge it to HEAD today.
Hmmm... do I remember correctly that I already gave a dtrace patch to you to check for futex problems? I think I changed the locking-probes since I gave the patch to you, but I'm not sure. Anyway, the patch against a recent -current is available from http://www.leidinger.net/FreeBSD/current-patches now.
yeah you're right. i've applied the patch and compiled and installed the kernel. i'm not very experienced with dtrace, so i'll need some instructions on how to proceed.
buildkernel suceeded, but i got this error during buildworld:
it seems your patch breaks building world with MODULES_WITH_WORLD defined. when modules get buildduring buildkernel, i don't see that error.
opt_kdtrace.h is generated by config. I've never used MODULES_WITH_WORLD, so I have no idea how this case is handled.
ahh ok. i've managed to get some stats via stats_timing.d. this is a snapshot during which a newly loaded tab in chromium was unresponsive for about 5 seconds. without the linux flash plugin running i never experienced such lock ups.
i've attached the d-script stats.
cheers. alex
Bye, Alexander.
