This patchset implements the IE (Invert Endian) bit in SPARCv9 MMU TTE.

It is an attempt of the instructions outlined by Richard Henderson to Mark
Cave-Ayland.

Tested with OpenBSD on sun4u. Solaris 10 is my actual goal, but unfortunately a
separate keyboard issue remains in the way.

A good explanation by Mark why the IE bit is required.

Thanks all for the feedback. Learnt a lot =)

v2:
- Moved size+sign+endianness attributes from TCGMemOp into MemOp.
  In v1 TCGMemOp was re-purposed entirely into MemOp.
- Replaced MemOp MO_{8|16|32|64} with TCGMemOp MO_{UB|UW|UL|UQ} alias.
  This is to avoid warnings on comparing and coercing different enums.
- Renamed get_memop to get_tcgmemop for clarity.
- MEMOP is now SIZE_MEMOP, which is just ctzl(size).
- Split patch 3/4 so one memory_region_dispatch_{read|write} interface
  is converted per patch.
- Do not reuse TLB_RECHECK, use new TLB_FORCE_SLOW instead.
- Split patch 4/4 so adding the MemTxAddrs parameters and converting
  tlb_set_page() to tlb_set_page_with_attrs() is separate from usage.
- CC'd maintainers.

v3:
- Like v1, the entire TCGMemOp enum is now MemOp.
- MemOp target dependant attributes are conditional upon NEED_CPU_H

v4:
- Added Paolo Bonzini as include/exec/memop.h maintainer

v5:
- Improved commit messages to clarify how interface to access
  MemoryRegion will be converted from "unsigned size" to "MemOp op".
- Moved cpu_transaction_failed() MemOp conversion from patch #11 to #9
  to make review easier.

v6:
- Improved commit messages.
- Include as patch #1 an earlier posted TARGET_ALIGNED_ONLY configure patch.
- Typeless macro SIZE_MEMOP is now inline.
- size_memop now includes CONFIG_DEBUG_TCG code.
- size_memop now also encodes endianness via MO_TE.
- Reverted size_memop operand "unsigned long" back to "unsigned".
- Second pass of size_memop to replace no-op place holder with MO_{8|16|32|64}.
- Delay memory_region_dispatch_{read,write} operand conversion until no-op
  size_memop is implemented so we have proper typing at all points in between.
- Fixed bug where not all memory_region_dispatch_{read,write} callers where
  encoding endianness into the MemOp operand, see patch #20.
- Fixed bug where not all memory_region_dispatch_{read,write} callers were
  collapsing their byte swap into adjust_endianness, see patch #20 and #22.
- Split byte swap collapsing patch (v5 #11) into #21 and #22.
- Corrected non-common *-common-obj to *-obj.
- Replaced enum device_endian with MemOp to simplify endianness checks. A
  straight forward sed but touched *alot* of files. See patch #16 and #17.
- Deleted enum device_endian.
- Deleted DEVICE_HOST_ENDIAN definition.
- Generalized the description of introduced MemTxAttrs attribute byte_swap.

I'm confused I think I already reviewed various patches of your previous
series but don't see my Reviewed-by tags.

Apologies Philippe! I am the confused one here =/


Will append.


Thank you very much for the reviews and qemu-devel newbie tips so far. I have felt very welcome.

Well for a newbie you did an impressive series!

The 'Reviewed-by' or 'Tested-by' tags help the maintainers to process
patches.

Since reviewing a series is time-consuming, if you iterate over a series
without changing some patchs, you should collect and amend the tags the
reviewers gave you, this way it helps them keep track of patches
reviewed and patches waiting for review.

In my case I find it very confuse when I look at a patch I already gave
my R-b tag and the tag is not here, I re-review the patch looking for
differences.

Often a reviewer asks for easy changes, and uses "with this changes:
R-b". If you addresses his comments you can then add his tag in the next
version.

If you split a reviewed patch in various, it is also OK to keep the tags
in all the splitted patches.

Regards,

Phil.

ppc parts

I think some of the DEVICE_NATIVE_ENDIAN / MO_TE ones are probably
wrong, but that's not within scope of this patch to fix.
