headers: remove sched.h from interrupt.h

2009-10-11T18:20:58+00:00

After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
Many thanks to Heiko Carstens for allowing this.

hpilo: add poll f_op

2009-09-15T16:50:48+00:00

of waiting for data.

hpilo: add interrupt handler

2009-09-15T16:50:48+00:00

Add interrupt handler to hpilo.  This is enablement for poll handler,
and it also simplifies the logic for handling an iLO reset, because now
only the interrupt handler needs to look for reset, the file system
interfaces only need to return failure when a reset has happened.

hpilo: staging for interrupt handling

2009-09-15T16:50:48+00:00

Refactor some hpilo routines in order to allow for locking changes in
interrupt handling.  Should not be functionally different.

hpilo: reduce frequency of IO operations

2009-04-01T15:59:18+00:00

Change hpilo open and close logic to spin for 10usec between checking device,
rather than every usec.

Because the loop is coded to take up to 10ms, it seemed prudent to
increase the interval between polling the device, to reduce the load on
the system and allow more other work to happen.

hpilo: open/close fix

2009-02-05T20:56:46+00:00

The device can take a while to respond to an open/close request, so
increase the time kernel will wait for response (1 ms to 10ms).

Also, properly clean up a channel on a failed open, by calling the channel
close routine.  Just freeing the memory isn't sufficient, the device needs
to be informed that the channel is no longer open, and the device memory
cleared of references to freed dma buffer.

HP iLO driver

2008-07-22T04:55:02+00:00

A driver for the HP iLO/iLO2 management processor, which allows userspace
programs to query the management processor.  Programs can open a channel
to the device (/dev/hpilo/dXccbN), and use this to send/receive queries.  
The O_EXCL open flag is used to indicate that a particular channel cannot
be shared between processes.  This driver will replace various packages
HP has shipped, including hprsm and hp-ilo.
