not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups
contain information suitable for allowing other parts of the kernel
to determine if a memory region is aligned to the largest data cache
line size present in the system.
Add a mips_dcache_compute_align() function which must be called whenever
one of the data cache line size variables is changed, in order to
compute mips_dcache_align and mips_dcache_align_mask.
executable mappings. Stop overloading VTEXT for this purpose (VTEXT
also has another meaning).
- Rename vn_marktext() to vn_markexec(), and use it when executable
mappings of a vnode are established.
- In places where we want to set VTEXT, set it in v_flag directly, rather
than making a function call to do this (it no longer makes sense to
use a function call, since we no longer overload VTEXT with VEXECMAP's
meaning).
VEXECMAP suggested by Chuq Silvers.
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.
Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.
COP0_SYNC
In R5900 mtc0, tlbr, tlbp, tlbwi, tlbwr must be followed by sync.p.
if defined MIPS3_5900, COP0_SYNC is defined as sync.p. else nothing.
IPL_ICU_MASK
mask interrupt directly ICU instead of SR.IM.
I've added this feature to support software interrupt for R5900.
and this option may be useful for platform which has cascaded ICU.
kernel compile flags as well as "-mlong-calls" so that calls from the
LKM in KSEG2 work to the kernel in KSEG0.
MIPS LKMs now build and can be loaded with the right Magick command line
args to modload(8). Changes to modload coming...
Thanks to Chris Demetriou for pointing out the -mlong-calls gcc option
that had been staring me in the face all along.
use command line parameters to ld(1) instead to set the endian format.
Clean up some endian decisions in mips/conf/Makefile.mips.
Wrap some long lines.
format specific.
Struct emul has a e_setregs hook back, which points to emulation-specific
setregs function. es_setregs of struct execsw now only points to
optional executable-specific setup function (this is only used for
ECOFF).
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.
Currently this is a no-op on most platforms, so they should see no difference.

need to check for curproc being non-NULL since none of the pmap
interfaces which are legal to use in interrupt handlers use this macro.
- use the hit op when flushing the cache in pmap_kremove().
- avoid trusting the optimizer in pmap_clear_reference().
- fix pmap_clear_modify() to reset the mod-bit emulation so we can
detect further modifications to the page, also flushing the cache
for any mappings which might have dirty lines.
