[PATCH v3 00/19] OpenRISC Architecture
From: Jonas Bonn
Date: Sun Jul 17 2011 - 11:12:56 EST
Here's v3 of the OpenRISC architecture patch series.
The major changes since version 2 are:
i) cleanup of the ptrace code
I've removed the single stepping code for now as I want to clean that up
separately. Will resubmit that in 3.2.
Have implemented exporting of thread state to userspace via the GETREGSET
mechanism. This allows us to keep the pt_regs structure opaque and allows
us to freely change the layout of the registers on the stack, which is
something that we will want to do in order to get better cache behaviour.
ii) rewrite of dma_alloc_consistent
iii) clean up device tree code in response to feedback for the v2 patch set
We only have a single example DTS file in the tree now, for the simulator,
that goes along with the defconfig file.
Aside from those three things, there are mostly cleanups coming from code
review and from checkpatch.
This tree should now be ready for inclusion in 3.1, but any feedback that
lets us be that much better is of course appreciated.
The code is available in the 'for-upstream' branch of the git repo at:
git://openrisc.net/jonas/linux
Note that there are 4 patches at the base of the branch changing asm-generic
behaviour and reviewed separately. Note also, that the code in the branch
depends on the devicetree/next branch and one patch from Rusty's patch set
for 3.1.
Thanks,
Jonas
