detailed information.
Steven J. Hill (10):
MIPS: Add core files for MIPS SEAD-3 development platform.
MIPS: Changes to configuration files for SEAD-3 platform.
MIPS: Add support for the M14K core.
MIPS: Add micro-assembler support for 'ins' and 'ext' instructions.
MIPS: GIC interrupt changes for M14K and SEAD-3 support.
MIPS: Code formatting fixes.
MIPS: Add support for early serial debug and LCD device on SEAD-3.
MIPS: MIPS32R2 optimisations for pipeline stalls and code size.
cobalt_lcdfb: LCD panel framebuffer support for SEAD-3 platform.
usb: host: mips: sead3: USB Host controller support for SEAD-3
platform.

More information about the SEAD-3 platform can be found at
<http://www.mips.com/products/development-kits/mips-sead-3/>
on MTI's site. Currently, the M14K family of cores is what
the SEAD-3 is utilised with.

is used with M14K cores. It also supports the new SEAD-3 platform
interrupt sources.

Add SEAD-3 support for early serial printk and the address for the
small LCD display. The actual framebuffer support is contained in
another patch.

If the CPU type is selected as MIPS32R2, then we can surround
some code with #ifdef's to reduce the binary size. Detect when
to use 'ehb' instruction to avoid pipeline stalls.

Also you might be interested in fls/ffs optimization using CLO/CLZ
instruction, that will be used in irq_ffs() at plat_irq_dispatch:

Not an extensive review -- just noticed this issue while browsing...
These two data definitions are clearly alphabetically ordered, so please
keep them as such. It seems rather a trivial update in this case -- just
swap the new entries. Thanks.

I would split the tlbex.c changes into a separate patch. The changelog
doesn't even mention the changes you are making to this file.

Can we somehow get rid of the #ifdef? You are already doing

Well I broke the ordering with a bunch of my patches lower down.
Perhaps we should fix it so it goes back to being ordered.

Kuribayashi-san,
I will certainly remove CONFIG_CPU_HAS_LLSC, thank you. I attempted to enable 'cpu_has_clo_clz' for SEAD-3, but it breaks my microMIPS-only kernel builds. Specifically, since microMIPS LL/SC instructions do not have 16-bit address offsets, in the '__cmpxchg_asm' macro function I get constraint errors because then the assembler has to use the %LO register in order to calculate the offset address. I am going to hold off on enabling the option until after the 3.5 release and then revisit for a solution. Thank you.
-Steve

Got it, find no problems with your plan. It seems there must be other
issues with optimization on microMIPS-only kernels :-)

It's OK to ask. :) Try using the "YC" constraint, this piece:
int test(void *p)
{
int i;
__asm__ __volatile__("ll\t%0,%1" : "=r" (i) : "YC" (*p));
return i;
}
assembles to:
ll $2,0($4)
jrc $31
for me (with "-O2 -mmicromips").
You may have to factor in backwards compatibility -- while "YC" is
supported both in the microMIPS and the standard MIPS mode, switching the
width of the immediate offset between 12 and 16 bits as appropriate, it's
certainly a new constraint older compilers did not support. I suggest
using a macro, as usually, you can use some existing examples as a
reference, e.g. <asm/compiler.h> (you know where to place this stuff now
too :) ).

I thought the "YC" constraint was only present in CodeSourcery toolchains, correct? If so, then that levies the requirement for a vendor-specific toolchain to build a microMIPS kernel. I do not consider that palpable. If it is not CodeSourcery-specific, then I will certainly try it out.

The GNU GPL applies, these sources are publicly available, so it's not
like anyone can't use them, integrate into their compiler, etc. Binutils
microMIPS support has already been integrated upstream.
Also is there any other compiler that makes microMIPS code? If so, then
I suggest that you convince its maintainers to make a compatible
constraint available. We'll need it sooner or later (you can force the
address into a register of course -- it was already considered a few years
ago before "R" was fixed in GCC to work reliably -- but I don't expect you
want such a pessimisation) and anyone implementing microMIPS support in
their compiler and willing to support building Linux will have to provide
the necessary constraint just as everyone already has to provide the "R"
constraint for standard MIPS code.
Note that as it is, you need to do something about all the code that uses
"R" with microMIPS instructions that have their immediate offset limited
to 12 bits anyway -- apart from <asm/cmpxchg.h> considered here this
includes stuff in <asm/futex.h> and <asm/r4kcache.h>. I maintain that
"YC" is your best bet especially given the little effort required to
handle it, and should any other compiler choose to use a different
constraint for this purpose, then it can be conditionalised on that
compiler's ID.
If you're concerned that "YC" can be used for something else in upstream
GCC, then we can coordinate this with GCC maintainers -- it's not like
we're running of of letters here.
