* remove the second void * argument on tasks.dlg2015-01-271-4/+4
| | | | | | | | | | | | | | | | | | | | | when workqs were introduced, we provided a second argument so you could pass a thing and some context to work on it in. there were very few things that took advantage of the second argument, so when i introduced pools i suggested removing it. since tasks were meant to replace workqs, it was requested that we keep the second argument to make porting from workqs to tasks easier. now that workqs are gone, i had a look at the use of the second argument again and found only one good use of it (vdsp(4) on sparc64 if you're interested) and a tiny handful of questionable uses. the vast majority of tasks only used a single argument. i have since modified all tasks that used two args to only use one, so now we can remove the second argument. so this is a mechanical change. all tasks only passed NULL as their second argument, so we can just remove it. ok krw@

Previously we were relying on specific DVACT_RESUME op's in drivers creating callback/threads themselves, but that has become too common, indicating the need for a built-in mechanism. ok dlg kettenis, tested by a sufficient amount of people

* Interrupt handlers should only return 1 if they did some work. Theclaudio2011-04-201-4/+5
| | | | | | | | | intrstat on arc may have other status bits set which are masked as interrupt cause and not handled by our driver. So the intrstat == 0 check does not work reliably. It is better to do use a variable that is set to 1 when work is done and the cause is cleared. This makes arc(4) behave on systems where interrupts are shared. OK deraadt@ dlg@

Previously we took from the head and returned to the tail, which meant that we were using the ccb that was the least recently used one which also means it has the smallest chance of being in cache. ok deraadt

Eliminates all SUCCESSFULLY_QUEUED and COMPLETE confusion and untangles the midlayer from the adapter a bit more.

| | | | | | | | | | | | | 4 bytes in the new firmware. To allow this to work on older firmwares add a "short read allowed" flag to arc_msgbuf(), which will allow short reads by getting the read length from the header of the response the firmware sends. Only set the flag on the arc_msgbuf() call that deals with the diskinfo struct for now. Discussed with and ok dlg@
