- Hello,
-
- I was thinking about the problems with interrupt driven HD drivers,
- that cause mint not to block while doing disk access.
- One problem is that we would need a kind of semaphore for the dma hardware
- as it has to be locked against duplicate accesses at the same time.
-
- As we have already one variable to do this, namely _flock, one could
- use this in all kind of software that accesses the dma hardware; or is
- it better to introduce a new semaphore, maybe separate ones for acsi and
- scsi? But then all existing software for HD would have to be changed to use
- it correctly.
-
- What do you think about it?
-
- Regards,
- Ulrich
