[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [Qemu-devel] [PATCH v7 00/42] Invert Endian bit in SPARCv9 MMU TTE
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.
v7:
- Fixed bug where size_memop was implicitly encoding MO_TE. Endianness,
{MO_TE|MO_BE|MO_LE}, is now explicitly encoded by MemoryRegion accessors.
- While a no-op, size_memop return type remains an unsigned.
- Use '= 0' short hand instead of macro logic to declare host endianness.
- With a new set of constant arguments, sanity checked the compiler is still
folding away tests in cputlb.c
- Re-declared many native endian devices as little or big endian. This is why
v7 has +16 patches.
