from HEAD to RELENG_7:
Add a new 'why' argument to kdb_enter(), and a set of constants to use
for that argument. This will allow DDB to detect the broad category of
reason why the debugger has been entered, which it can use for the
purposes of deciding which DDB script to run.
Assign approximate why values to all current consumers of the
kdb_enter() interface.
For ABI/KPI reasons, the MFC creates a new function, kdb_enter_why(),
with the new argument, updating existing consumers to use that,
preserving kdb_enter() with the current argument, and wrapping it around
kdb_enter_why().

Don't use a time-limiting loop that's defined in terms of the baudrate2007-04-03T01:21:10ZMarcel Moolenaarmarcel@FreeBSD.org2007-04-03T01:21:10Zurn:sha1:35777a2a79dec37cdacb86cac0e87e23465e2d7d
in the putc() method. Likewise, in the getc() method, don't check for
received characters with an interval defined in terms of the baudrate.
In both cases it works equally well to implement a fixed delay. More
importantly, it avoids calculating a delay that's roughly 1/10th the
time it takes to send/receive a character. The calculation is costly
and happens for every character sent or received, affecting low-level
console or debug port performance significantly. Secondly, when the
RCLK is not available or unreliable, the delays could disrupt normal
operation.
The fixed delay is 1/10th the time it takes to send a character at
230400 bps.
Don't expose the uart_ops structure directly, but instead have2007-04-02T22:00:22ZMarcel Moolenaarmarcel@FreeBSD.org2007-04-02T22:00:22Zurn:sha1:f8100ce2a70db5c60672578fee913d986ac1cf01
it obtained through the uart_class structure. This allows us
to declare the uart_class structure as weak and as such allows
us to reference it even when it's not compiled-in.
It also allows is to get the uart_ops structure by name, which
makes it possible to implement the dt tag handling in uart_getenv().
The side-effect of all this is that we're using the uart_class
structure more consistently which means that we now also have
access to the size of the bus space block needed by the hardware
when we map the bus space, eliminating any hardcoding.
For embedded UARTs compatible with the ns8250 family it is possible2007-03-28T18:34:59ZMarcel Moolenaarmarcel@FreeBSD.org2007-03-28T18:34:59Zurn:sha1:ebecffe930384eb44d9ba75f052d25b9dc41c91d
that the driver clock is identical to the processor or bus clock.
This is the case for the PowerQUICC processor. When the clock is
high enough, overflows happen in the calculation of the time it
takes to send 1/10 of a character, used in delay loops. Fix the
overflows so as to fix bugs in the delay loops that can cause either
insufficient delays or excessive delays.
