Hydra has these evaluation errors:
at `nixpkgs.linuxPackages.lttngModules.i686-linux' [nixosSrc = ..., nixpkgs = ..., officialRelease = false]:
value is an attribute set while a string was expected
because licenses.mit is an attribute set and not a string.
TODO: Licenses in pkgs/lib/licenses.nix are a mix of attr sets and
strings, this needs to be standardized.
Add linux kernel modules needed to do kernel tracing with LTTng.
To make them available to lttng in NixOS, add this to configuration.nix:
boot.extraModulePackages = [ pkgs.linuxPackages.lttngModules ];
Babeltrace is a command-line tool and library to read and convert LTTng
tracefiles. Give it a (binary) trace file/dir path and it will print a
human readable event log to standard out.
This is the Linux Trace Toolkit. Included in this package:
Command-line client:
lttng
Tracing daemons:
lttng-sessiond (automatically started by lttng)
lttng-relayd (remote trace collection daemon)
Userspace tracing can be done by using liblttng-ust. To do kernel
tracing we also need the LTTng kernel modules.
I've added a patch that changes "/sbin/modprobe" to just "modprobe".
This reverts commit 67a46ce928.

It has been submitted for inclusion in mainline, so it will probably
make it into 3.11 (or 3.12 as 3.11 is fairly close to release).
It is very local, only affecting people who use the "send" feature.
Without it, send is unstable/unsafe to use incrementally.
It can probably be applied to 3.9 and 3.8 as well, but as I only
tested it against 3.10, so I didn't bother.
The videos work, but there is a problem with sound:
ALSA lib dlmisc.c:236:(snd1_dlobj_cache_get) Cannot open shared library
/nix/store/9z51hr9l19vdhgmqd60jwwrg6ny5md2d-alsa-plugins-1.0.26/lib/alsa-lib/libasound_module_pcm_pulse.so
It tries to open a 64bit plugin, which obviously fails. I think this depends on
/etc/asound.conf, but I'm not sure how to fix it.
Regardless of the problem, in one computer I tried the sound works but other
apps cannot output sound. In another, the sound doesn't work and other apps
continue working as normal.
