Converting to condvar(9) [Was: Re: CVS commit: src/sys/dev/ieee1394]
Christoph Egger christoph_eg...@gmx.de wrote: Log Message: don't call tsleep() with any mutexes hold To generate a diff of this commit: cvs rdiff -u -r1.23 -r1.24 src/sys/dev/ieee1394/fwdev.c The right fix would be to use condvar(9). Generally, tsleep(9) should be replaced and removed in the longer term. Sure. Two questions hold me back from doing this: 1. Which cv_*wait* variant should be used? 2. Where should I add the corresponding cv_signal/cv_broadcast ? Is it possible to have an conversion example in the tsleep(9) manpage? OK, some notes. The ltsleep(9)/tsleep(9)/mtsleep(9) and wakeup(9) pairs should generally be replaced by cv_wait*(9) and cv_broadcast(9) pairs, as the former API is obsolete. It depends which cv_wait*(9) variant to use. Simplistic way - look at the corresponding ltsleep(9) usage. There are two arguments of interest: timo and priority. The priority value may have ORed such flags: PNORELOCK and PCATCH. The PCATCH means that blocking thread should be awoken on signal, which would be done by cv_wait_sig(9). The timo value, if it is not zero, indicates how long to sleep - replace it with cv_timedwait(9). If both specified, there is cv_timedwait_sig(9), and if none - there is cv_wait(9). Interlock (mutex) must be held across cv_wait*/cv_broadcast calls, in order to protect our state. Which means that some old code might require amending (to remove PNORELOCK or replace simple_lock(9) use) or addition of locking. That is simplistic, because converting should not be done mechanically i.e. blindly. Code logic should be understood before changing, and it may also need to be revisited for the change. Please also read condvar(9) and ltsleep(9) manual pages - all the details are well described there. -- Mindaugas

If you break HEAD and you leave it broken for days, without communicating status, consider your changes a candidate for backout. I want to also stress that I tried to fix the firewire code; I fixed two issues already, and then I saw that it would require a lot of reworking to fix the xfer code. I filed a PR, and I backed out the changes because in my judgement there is no quick and easy fix for it. Prove me wrong and commit today or tomorrow a change that works. christos
