chris | Fix kernel boot issue on cats.
The delay(9) loop, used before the clock device is probed and a hardware timer
is available, was out by a factor of 625.
This wasn't an issue until revision 1.45 of sys/dev/ic/pckbc.c which switched
to using delay(9) when polling the keyboard controller.
Cats attaches the console (and pckbc) before the clock has been probed, and so
the delay loop code is used causing issue with the keyboard polling.

Interrupt handling changes, in discussion since February:
- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

Convert netwinder and cats (and any other footbridge based system in the
future) to timecounters, using the dc21285_fclk. ok nick@, chris@.

gdamore | ANSIfy, and KNF fixes.

chris | branches: 1.21.8;
Simplify delay loop by moving the maths to before the loop.
There is minimal risk of overflow unless something delays >134s.

Adapt to shadowing and qualifier-cast warnings.
|

matt | Add SA_SIGINFO support for ARM (from Chris Gilbert).
|
| 1.17 |
| 23-Mar-2003 |
chris | branches: 1.17.2;
Add __KERNEL_RCSID tags to footbridge files.

thorpej | Merge the nathanw_sa branch.

chris | Checkin new interrupt handling code for the footbridge.
This is based upon Jason's work on xscale.
Most of the interrupt handling code is now written in C using an asm stub to
call into the C code.
spl* now only updates a software mask, and does not update the hardware,
this should be much faster.
The new code works well on cats, it's untested on netwinder, but should work.
The code implements generic soft interrupts.
More work is still required to bring the isa interrupt handling code upto
scratch currently all isa interrupts are handled at IPL_BIO on the footbridge.
This may cause isa interrupts to be handled later than they should be.
I plan to fix this in the near future.

tsutsui | Initialize statprev in setstatclockrate().

| 10-Oct-2002 |
chris | branches: 1.13.2;
Fix thinko from this morning, delay is reentrant, so resetting the timer
to 0 on entry will confuse any already running delay.
|
| 1.12 |
| 10-Oct-2002 |
chris | Minor tweaks to footbridge's delay, always reset the timer when starting delay run (and set last to the counter value).
When the read value is 0, reset the timer (don't wait till the next loop round to reset it)
Add a bit of debug to the calibration stuff to make sure its working ok.
|
| 1.11 |
| 05-Oct-2002 |
chris | Add random jitter to stat clock, the random jitter is +- 511 usec's, so
we should average the nominal clock rate.
stathz now runs at hz (the hard clock hz), without getting high amounts of
time in interrupt handling.
|
| 1.10 |
| 02-Oct-2002 |
thorpej | Use CFATTACH_DECL().
|
| 1.9 |
| 28-Sep-2002 |
chris | Enable the use of a seperate statclock.
Currently statclock runs at 64hz, maybe it should be faster or slower, I did
try it being the same as hz, but that just made it look like we spent 10% of
time handling interrupts, rather than the 3% that this gives.
Also fix the IPL_LEVELS for netwinder.
|

thorpej | Declare all cfattach structures const.
|

| 27-Sep-2002 |
provos | remove trailing \n in panic(). approved perry.
|
| 1.6 |
| 04-May-2002 |
chris | Implement a proper delay routine for footbridge based systems. Note that
until the footbridge is attached we still have to rely on a loop. This
uses TIMER_3 running at 100Hz.
Sadly this doesn't appear to fix the tlp problems, which either means that this
delay routine is not as accurate as it should/could be or tlp is still broken.

mycroft | Fix off-by-one error in delay().

chris | Make some of the arm32 files build with LOOSE_PROTOTYPES not set in the makefile. Turned up a few mismatched functions. Note that this isn't all of the arm32 files. Aim will be to get arm32 kernels built with LOOSE_PROTOTYPES not set.
|
| 1.3 |

thorpej | Use <arm/cpufunc.h>, not <machine/cpufunc.h>.
|
| 1.2 |
| 05-Sep-2001 |
matt | branches: 1.2.6;
Change <machine/irqhandler.h> to <machine/intr.h> since the latter always
includes the former and is a standard include file.
|
| 1.1 |
| 09-Jun-2001 |
chris | branches: 1.1.2;
Move the footbridge dir out of arm32 into arm.
