41d99511cb - Fix off-by-one bug in arge_fixup_rx. If mbuf is located 
by the end of the page and even number of bytes long,
    that may cause TLBMiss exception for unallocated address.
- Fix mess with DMA sync opeartions

b661054728 - Move dpcpu initialization to mips_proc0_init. It's 
more appropriate place for it. Besides dpcpu_init
    requires pmap module to be initialized and calling it
    int pmap.c hangs the system

4d33e6554c 64-bit fixes: fix printf formats and prefer MIPS_PHYS_TO_KSEG0. 2009-07-06 18:18:27 +00:00

a371f04d66 GC some now-unused items. Fix for 64-bit build. Note: this breaks 
the 32-bit build (which we're not computing correctly anyway).

4df29a25aa 64-bit fixes: 
(1) fix printf formats.
(2) Prefer FreeBSD's MIPS_PHYS_TO_KSEG0 to hand-rolled one from Cavium.
(3) Mark a few 64-bit cleanliness issues (possible).
(4) Minor formatting fixes.

e0dab9bcb8 Be more pedantic here. If we're going to shift something 
sizeof(long)*8 / 2 bits, then we better make sure we're shifting a
long that much, not an int.

# I'm surprised this is code would have a bug this basic.

e3c2111d5c Use ta0 instead of t4 and ta1 instead of t5. These map to the same 
registers on O32 builds, but t4 and t5 don't exist on N32 or N64.

10c8cc2b9f Use better casts for passing the small integer as a pointer here.

ece5503dbe (1) Use PTR_LA rather than bare la for N64 goodness (it is dla there)

4f4793e605 use "PTR_LA" in preference to a bare la so it translates to dla on 
64-bit ABIs.

add6da074c Now that we define atomic_{load,store}_64 inline in atomic.h, we don't 
need to define them here for the !N64 case.

We now define atomic_readandclear_64 in atomic.h, so no need to repeat
it here.

61a1eed0b4 First cut at atomics for 64-bit machines and SMP machines. 
# Note: Cavium provided a port that has atomics similar to these, but
# that does a syncw; sync; atomic; sync; syncw where we just do the classic
# mips 'atomic' operation (eg ll; frob; sc).  It is unclear to me why
# the extra is needed.  Since my initial target is one core, I'll defer
# investigation until I bring up multiple cores.  syncw is an octeon specific
# instruction.

753b803f71 use %p in preference to 0x%08x for printing register_t values. Cast 
them to void * first.  This neatly solves the "how do I print a
register_t" problem because sizeof(void *) is always the same as
sizeof(register_t), afaik.

0d978536b2 Pull in machine/cdefs.h for the ABI definitions. Provide a PTR_LA, 
ala sgi, and use it in preference to a bare 'la' so that it gets

da96ff5dae Define __ELF_WORD_SIZE appropriately for n64. Note for N32 I believe 
this is correct.  While registers are 64-bit, n32 is a 32-bit ABI and
lives in a 32-bit world (with explicit 64-bit registers, however).
Change an 8, which was 4 + 4 or sizeof(int) + SZREG to be a simple '4
+ SZREG' to reflect the actual offset of the structure in question.

2c1c8bb345 Switch to ABI agnostic ta0-ta3. Provide defs for this in the right 
places.  Provide n32/n64 register name defintions.  This should have
no effect for the O32 builds that everybody else uses, but should help
make N64 builds possible (lots of other changes are needed for that).

f1eccd05ec In vn_vget_ino() and their inline equivalents, mnt_ref() the mount point 
around the sequence that drop vnode lock and then busies the mount point.
Not having vlocked node or direct reference to the mp allows for the
forced unmount to proceed, making mp unmounted or reused.
