[Qemu-devel] [PATCH 00/16] target-sparc improvements

[Richard Henderson]

The two main goals in this patch set are:

 * Make use of the new MO_ALIGN_* flags, to allow less use of
   check_align, and support partially misaligned fp memory ops.

 * More cleanups for ASIs, in the end using the new atomic ops.

The final two patches require the "cmpxchg atomic" v5 patch set
which I posted yesterday.  Otherwise this patch set should apply
to master.  The full tree is at

  git://github.com/rth7680/qemu.git tgt-sparc-6

There is overlap with Artyom's sun4v patch set.

  * MMU_PHYS_IDX cleans up patch 14 (use direct address translation
    in hyperprivleged mode).  And if I read patch 9 correctly, may
    allow MMU_HYPV_IDX to be redundant with MMU_PHYS_IDX.  Which would
    be nice, because 7 or more mmu idxes causes the sizes of each of
    the tlb's to be reduced.

  * The patches that touch the asi's will probably conflict.
