[S390] qdio: convert global statistics to per-device stats

2010-01-04T08:05:58+00:00

Revamp the qdio performance statistics and move them from procfs to
debugfs using the seq_file interface. Since the statistics are not
intended for the general user the removal of /proc/qdio_perf should
not surprise anyone.

The per device statistics are disabled by default, writing 1 to
//qdio//statistics enables the
statistics for the given device.

[S390] cio: move scsw helper functions to header file

2009-09-11T08:29:36+00:00

All scsw helper functions are very short and usage of them shouldn't
result in function calls. Therefore we move them to a separate header
file.
Also saves a lot of EXPORT_SYMBOLs.

[S390] cio: Add chsc subchannel driver.

2008-07-14T08:02:12+00:00

This patch adds a driver for subchannels of type chsc.

A device /dev/chsc is created which may be used to issue ioctls to:
- obtain information about the machine's I/O configuration
- dynamically change the machine's I/O configuration via
  asynchronous chsc commands

2008-07-14T08:02:11+00:00

This interface makes it easy for drivers to register usage of different
I/O interruption subclasses without needing to worry about possible
other users of the same isc.

provide helper functions for easier access to fields which are present
in both the traditional as well as the modified format.
