sys/dev/amr amr.c amr_cam.c amr_disk.c amr_pci.c
amrvar.h
Log:
Lock the AMR driver:
- Introduce the amr_io_lock to control access to command queues, bio queues,
and the hardware.
- Eliminate the taskqueue and do all completion processing in the ithread.
- Assign a static slot number to each command instead of doing a linear
search for free slots each time a command is needed.
- Modify the interrupt handler to more closely match what Linux does, for
safety.
