- Move away from using CPUISMIPS3; use MIPS_HAS_R4K_MMU instead.
- Bump the Sysmap size a little for large-memory machines.
XXX: still need work, especially in pmap_procwr().
- Use a table-driven CPU detection algorithm instead of multiple
case statements.
- Add MIPS32/64 feature detection using the architected CP0 registers
(from Broadcom Corp).
- Call MD mips_machdep_cache_config() function if
__HAVE_MIPS_MACHDEP_CACHE_CONFIG is defined - used to set up the
L2 cache on some ports.
- Remove all mmu-related code that may use 32 register on mips32-style
implementatios and move them to mipsX_subr.S - which is then included
from mips{3,32,64,5900}_subr.S with various control defines enabled.
- Remove local cache instruction flags
- Add badaddr64 (from Broadcom Corp).
- Add mips32 and mips64 locore function prototypes.
- Add mips3_lw_a64() and mips3_sw_a64() for access data at any
64bit address (from Broadcom Corp).
- Add Broadcom and Sandcraft CPU company ids.
- Add XKPHYS macros (from Broadcom Corp).
- Add some r5900 register bit definitions.
- Add extra exception vector addresses for mips32/mips64 and r5900.
- Make the mips cp0 register definitions available from both asm and C.
- Add some Alchemy and Sandcraft CPU ids.
- Add r3000, tx39xx and r4x00 CPU revision ids.
- Remove defines for the number of TLBs on some CPUs.
- Add alignment-safe double and float unions.
- Use the above for the __infinity and __nan constants on all
architectures that use the standard ieee754 representation of
those constants.
- Add a single copy of various ieee754 math functions (frexp, isinf,
isnan, ldexp and modf) that had numerous duplicates among the
arch-specific directories.
- Use the above functions on all architectures where the generic C
versions where used. Architectures that had local assembly
routines are untouched (for those functions only).
Any problems reported by testers have been fixed, and massive
cross-compiling of kernels has shown that any problems that remain
with actually building kernels are not related to this.
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.
