Subject: [Qemu-devel] [PATCH v2 0/3] cputlb: Adjust tlb bswap implementation
Date: Thu, 12 Sep 2019 15:59:31 -0400 [thread overview]
Message-ID: <20190912195934.13502-1-richard.henderson@linaro.org> (raw)
Changes from v1:
* Move QEMU_ALWAYS_INLINE to qemu/compiler.h.
* Rename some inline wrapper functions.
* Don't break TLB_NOTDIRTY in patch 3.
Blurb from v1:
The version that Tony came up with, and I reviewed, doesn't actually
work when applied to RAM. It only worked for i/o memory. This was
the root cause for
https://lists.gnu.org/archive/html/qemu-devel/2019-09/msg00036.html
I tried a couple of different approaches in load/store_helper, but
this is the one that didn't affect the normal case -- a simple tlb
miss against (non-swapped) ram.
