| ftonello | Is there any multi-threading extension to lv2 besides worker? | 14:26 |

| rgareus | ftonello: no | 15:42 |
| rgareus | ftonello: I suggest to try very hard to avoid multi-threading in plugins. plugins have too little context (other plugins, host-state, rt-priority of the host..) to safely use threads. | 15:45 |

| ftonello | rgareus: Yes, I know. I am want is something very specific for Embedded Linux, where the environment is highly controlled and resources are available for multi-threading in real-time. | 17:45 |
| ftonello | I am writing a pseudo-lv2 host where I want to run plugins that might need this functionality. Usually a polyphonic synth. | 17:46 |
| rgareus | ftonello: so the goal is to allow the synth to use all cores? | 17:50 |
| rgareus | and in your embedded system, the synth is likely the only plugin. | 17:50 |
| rgareus | (no other parallel tasks) | 17:50 |
| rgareus | ? | 17:51 |
| *** ssj71 has joined #lv2 | 18:04 | |
| ftonello | rgareus: Yes. And it usually is the only plugin, but it can have more and the cores allocation can be customized. | 18:08 |
| drobilla | I doubt API other than maybe being able to set some multi-threading related parameters (easy with options) would be particularly useful in that respect | 18:13 |
| *** ftonello has quit IRC | 18:13 | |
| drobilla | Maybe to avoid the questionably-RT 'wait for everyone to finish' thing that happens with callbacks (like that jack non-callback interface) | 18:14 |

| ssj71 | sorry, I got disconnected yesterday is it known that lv2:designation lv2:enabled ; fails sord_validate or am I doing something wrong? | 20:33 |
| rgareus | ssj71: sounds like you have an old version of the lv2 headers/specs installed | 20:52 |
| rgareus | ssj71: you need lv2 version 14.0 (2016-09-18) | 20:53 |
| ssj71 | ah good | 20:58 |
| ssj71 | not sure how to check my current version of lv2 | 20:59 |
| ssj71 | but its whatever is in falk's repos | 20:59 |
| rgareus | ssj71: to validate, I use a git clone of the lv2 repo | 21:00 |
| ssj71 | makes sense | 21:00 |
| rgareus | and lv2validate -> shell script exec sord_validate `find ~/src/lv2/ -name '*.ttl' | grep -v plugins` "$@" | 21:00 |
| rgareus | ~/src/lv2/ is lv2-git and the grep is to get rid of the bundled example plugins' ttl | 21:01 |
| rgareus | ssj71: actually I also do some MOD work. and to that end I also have a mod-sdk clone. sord_validate `find ~/src/lv2/ -name '*.ttl' | grep -v plugins` `find ~/src/mod-sdk -name '*.ttl'` "$@" | 21:02 |
| rgareus | that way also plugins using MOD extensions validate | 21:02 |
| ssj71 | hmm, falk must put the mod extensions in kxstudio, because my mod extensions validate fine | 21:03 |
