add lkmenodev prototype.
|
|
very usefull (for <sys/vnode.h> inclusion).
from the other side this is really machine independent ...
tested w/ i386, but should not cause errors w/ other arch's.
pls, test it (don't forget to reconfig kernel ;)

the device interrupt chain structures (isa, pci)
Move interrupt chain structure definition to <machine/psl.h> so vmstat can
get at it (i386)
Remove hack to count interrupts the old way (i386)

New generic disk framework. Highlights:
New metrics handling. Metrics are now kept in the new `struct disk'.
Busy time is now stored as a timeval, and transfer count in bytes.
Storage for disklabels is now dynamically allocated, so that the size
of the disk structure is not machine-dependent.
Several new functions for attaching and detaching disks, and handling
metrics calculation.
Old-style instrumentation is still supported in drivers that did it
before. However, old-style instrumentation is being deprecated, and
will go away once the userland utilities are updated for the new
framework.
For usage and architectural details, see the forthcoming disk(9)
manual page.

The IST_* and IPL_* constants are not bus-specific; don't treat them as such.

IO bus for 3000-family boxes is now "tcasic" when then attaches tc.
esp_iomem is unnecessary, has been unnecessary for a while,
apparently.

portability definitions for machine-independent TC configuration code.

deal with renaming of asic to ioasic, and other new-tc-config changes

machine-independent TurboChannel bus configuration. These files
deal with stuff like:
(1) configuring built-in devices,
(2) looking at TC slots configuring any devices found.
The lists of slots, slot locations, etc. and built-in devices
are provided by machine-dependent code. Interrupt handling
is also provided by machine-dependent code, but the MD code provides
hooks so that standard names for 'establish' and 'disestablish'
can be used in drivers.
This code requires <machine/tc_machdep.h>, which defines some
portability types specific to the TurboChannel bus code.
