Bug ID: 110249
Summary: IGT command line tools load redundant GUI libraries
Product: DRI
Version: DRI git
Hardware: Other
OS: All
Status: NEW
Severity: minor
Priority: medium
Component: IGT
Assignee: dri-devel@lists.freedesktop.org
Reporter: eero.t.tammi...@intel.com
IGT command line tools load many unnecessary libraries, because they use
libigt.so which links in a huge amount of libraries:

For example "intel_gpu_top" seems to need just these symbols from it:
$ readelf -s intel_gpu_top |grep igt
10: 0000000000000000 0 FUNC GLOBAL DEFAULT UND igt_perf_open_group
28: 0000000000000000 0 FUNC GLOBAL DEFAULT UND igt_perf_open
58: 00000000002060a0 200 OBJECT GLOBAL DEFAULT 25 igt_subtest_jmpbuf
113: 0000000000000000 0 FUNC GLOBAL DEFAULT UND igt_perf_open_group
124: 00000000002060a0 200 OBJECT GLOBAL DEFAULT 25 igt_subtest_jmpbuf
139: 0000000000000000 0 FUNC GLOBAL DEFAULT UND igt_perf_open
And sone other functions it needs are some json and printing helpers + normal
libc stuff. It does NOT need freetype, pixman, Cairo, ALSA sound, X11
libraries, libglsl etc stuff brought in by libigt.
It's annoying to need to install these redundant dependencies on e.g. headless
media transcoding server if one just wants to use intel_gpu_top to monitor GPU
utilization.
Wouldn't it make sense to split libigt up a bit, e.g. to GUI and non-GUI bits?
