Subject: [PATCH 0 of 3] MMIO 32-bit copy routine, the final frontier
Date: Wed, 11 Jan 2006 14:39:54 -0800 [thread overview]
Message-ID: <patchbomb.1137019194@eng-12.pathscale.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 722 bytes --]
After yet more review comments from several people, here is a reworked
set of 32-bit MMIO copy patches. This may even be the final set.
These define the generic __raw_memcpy_toio32 as a weak symbol, which
arches are free to override. We provide a specialised implementation
for x86_64.
These patches should apply cleanly against current -git, and have been
tested on i386 and x86_64.
The patch series is as follows:
raw_memcpy_io.patch
Introduce the generic MMIO 32-bit copy routine.
x86_64-memcpy32.patch
Add memcpy32 routine to x86_64.
arch-specific-raw_memcpy_io.patch
Get each arch to use generic memcpy_io code, except x86_64, which
uses memcpy32.
