ff28c51cc0 Make cpu_getmcontext() run the PC through ras_lookup() so that kernel 
getcontext() plus userlevel setcontext() (as used in libpthread) respects
the atomicity of RAS regions.

9bd03b1f69 Cast the arg to MIPS_KSEG0_TO_PHYS() in POOL_VTOPHYS() (thanks, nathan!). 2003-04-09 22:10:58 +00:00
thorpej
a0aee79a1d Add the ability for pool caches to cache the physical address of 
objects.  Clients of the pool_cache API must consistently use
the "paddr" variants or not, otherwise behavior is undefined.

Enable this on Alpha, ARM, MIPS, and x86.  Other platforms must
define POOL_VTOPHYS() in the appropriate manner in order to enable
the feature.

Part 1 of a series of simple patches contributed by Wasabi Systems
to improve network performance.

d38e1fa853 Use "rxintr" for the name of the receive interrupts evcnt instead 
of "txintr".  Much less confusing that way...

33fcc94c6f Add support for R5k secondary caches, from code Chris Sekiya sent me a long 
time ago, with small tweaks by me.  Since the R5k doesn't do VCE, the pmap
still needs to be whacked for R5kSC CPUs to work correctly, but this is a
start.

bc735179e8 use COP0_HAZARD_FPUENABLE in a couple more places when turning on FP: 
In start (noticed after looking for more COP_1_BIT uses, and note
that there are extra nops here but really they don't hurt), and in
MachFPTrap (noticed by ... running regress!).

0cc0813590 Add the MIPS3_CONFIG_SE (name taken from Rm52xx manual) bit, which is the 
external cache enable bit -- this allows software to enable or disable the
(external) L2 cache on the R5k and Rm527x and the (external) L3 cache on
the Rm7k.  If the (external) cache is disabled, treat it as if there were
no cache for the purposes of the cache setup code.

Also, update sgimips code to use the new name.

4a06119a9d Pass the system call table to trace_enter() and ktrsys() so that it is 
possible to use alternate system call tables. This is usefull for
displaying correctly the arguments in Mach binaries traces.

If NULL is given, then the regular systam call table for the process is used.

5b6caeca74 Mark the Au1x00 CPUs as having a fully coherent data cache that doesn't 
require flushing (even in the instruction cache handlers).  This gives
about a 4% improvement in a "make depend" benchmark.

Mark the SB-1 CPUs as having a fully coherent data cache that only
require flushing in the instruction cache handlers.  This gives about
a 5% improvement in a "make depend" benchmark.

or not at all.  Currently only used by MIPS32/MIPS64 cache code.
