Not sure if anybody here knows, but alsa-plugins is not the only set of |
2 |
plugins an user installs in its system, many others are installed by alsa-lib |
3 |
itself, they are the basic plugins like dmix, dsnoop, iec958, plug... the |
4 |
ones that many asoundrc already make use of. |
5 |
|
6 |
Now of course, most of the users need them, and disabling them would be pretty |
7 |
bad, but again, there are reasons to disable some of them at least, |
8 |
especially when targetting small embedded devices. |
9 |
|
10 |
If nobody has anything against this, I'll add an ALSA_PCM_PLUGINS variable |
11 |
where users can choose the plugins they want built, to reduce the amount of |
12 |
code installed by alsa-lib: |
13 |
|
14 |
Calculating dependencies... done! |
15 |
[ebuild R ] media-libs/alsa-lib-1.0.14_rc1 USE="-alisp -debug -doc -midi" |
16 |
ALSA_PCM_PLUGINS="-adpcm -alaw -asym -copy -dmix -dshare -dsnoop -empty -extplug -file -hooks |
17 |
iec958 -ioplug -ladspa -lfloat -linear -meter -mulaw -multi -null |
18 |
plug -rate -route -share -shm -softvol" 0 kB |
19 |
|
20 |
As you can see, my system even if it's not an embedded system is skipping most |
21 |
of them, as I don't use dmix or dsnoop (I'd rather leave it to PulseAudio, |
22 |
that for me had better results) and I don't have much more use for my |
23 |
soundcard but playing music and DVDs. |
24 |
|
25 |
The default for them, in base/ profile directly, should be of _all_ of them. |
26 |
There's not the problem as for ALSA_CARDS that some of them have dependencies |
27 |
or that they might change between versions, as this configure is smarter and |
28 |
filters them already. |
29 |
|
30 |
As you can see, the modified ebuild I'm currently using also has two more |
31 |
useflags, midi and alisp: the first disable all the support for sequencer, |
32 |
rawmidi, instrumentation and samples loading, I think that nowadays most of |
33 |
the people simply don't care about that it so it might be worth having it as |
34 |
useflag (SuSE seems to disable at least sampleloading), while the latter |
35 |
disables alisp interpreter for advanced (and complex) configuration (SuSE |
36 |
also disable this). |
37 |
|
38 |
The result is quite good after all; with a -ggdb compiled alsa-lib packages, I |
39 |
get this change in the size of the package: |
40 |
|
41 |
flame@enterprise ~/devel/gentoo-x86/media-libs/alsa-lib % qsize alsa-lib |
42 |
media-libs/alsa-lib-1.0.14_rc1: 133 files, 25 non-files, 6608.758 KB |
43 |
flame@enterprise ~/devel/gentoo-x86/media-libs/alsa-lib % qsize alsa-lib |
44 |
media-libs/alsa-lib-1.0.14_rc1: 127 files, 22 non-files, 3666.628 KB |
45 |
|
46 |
it is almost the half. |
47 |
|
48 |
So, anybody has reasons not to pursue this road? |
