[asterisk-bugs] [JIRA] (DAHLIN-290) dahdi_dynamic_eth have a huge jitter on transmit

[Pavel Selivanov (JIRA)]

    [ https://issues.asterisk.org/jira/browse/DAHLIN-290?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=201608#comment-201608 ] 

Pavel Selivanov commented on DAHLIN-290:
----------------------------------------

Any news on problem ?
Actually, I think it (workqueue or tasklet) should be moved to dahdi_dynamic.

dynamic already has tasklet.
dynamic should start tasklet on rx (default untill dahdi 2.6.x), on tx(will solve this bug), or not used at all.
We can set a flag in dahdi_dynamic_driver, irq_safe_tx (zero by default).

> Seems, using a common "thread" can produce a huge jitter.
> Since this "common" thread can be used by any driver - it can't guarantee 1ms...
