* [PATCH 4/4] powerpc: Change PACA from SPRG3 to SPRG1
From: Benjamin Herrenschmidt @ 2009-07-15 6:52 UTC (permalink / raw)
To: linuxppc-dev
This change the SPRG used to store the PACA on ppc64 from
SPRG3 to SPRG1. SPRG3 is user readable on most processors
and we want to use it for other things. We change the scratch
SPRG used by exception vectors from SRPG1 to SPRG2.

* [PATCH 3/4] powerpc: Remove use of a second scratch SPRG in STAB code
From: Benjamin Herrenschmidt @ 2009-07-15 6:52 UTC (permalink / raw)
To: linuxppc-dev
The STAB code used on Power3 and RS/64 uses a second scratch SPRG to
save a GPR in order to decide whether to go to do_stab_bolted_* or
to handle a normal data access exception.
This prevents our scheme of freeing SPRG3 which is user visible for
user uses since we cannot use SPRG0 which, on RS/64, seems to be
read-only for supervisor mode (like POWER4).
This reworks the STAB exception entry to use the PACA as temporary
storage instead.

* [PATCH 2/4] powerpc: Use names rather than numbers for SPRGs (v2)
From: Benjamin Herrenschmidt @ 2009-07-15 6:52 UTC (permalink / raw)
To: linuxppc-dev
The kernel uses SPRG registers for various purposes, typically in
low level assembly code as scratch registers or to hold per-cpu
global infos such as the PACA or the current thread_info pointer.
We want to be able to easily shuffle the usage of those registers
as some implementations have specific constraints realted to some
of them, for example, some have userspace readable aliases, etc..
and the current choice isn't always the best.
This patch should not change any code generation, and replaces the
usage of SPRN_SPRGn everywhere in the kernel with a named replacement
and adds documentation next to the definition of the names as to
what those are used for on each processor family.
The only parts that still use the original numbers are bits of KVM
or suspend/resume code that just blindly needs to save/restore all
the SPRGs.

* [PATCH 1/4] powerpc: Rename exception.h to exception-64s.h
From: Benjamin Herrenschmidt @ 2009-07-15 6:52 UTC (permalink / raw)
To: linuxppc-dev
The file include/asm/exception.h contains definitions
that are specific to exception handling on 64-bit server
type processors.
This renames the file to exception-64s.h to reflect that
fact and avoid confusion.

* riscwatch shows up core status UNKNOWN for 970mp ppc processor
From: anil kumar @ 2009-07-15 5:15 UTC (permalink / raw)
To: linuxppc-dev
[-- Attachment #1: Type: text/plain, Size: 3588 bytes --]
Hello
I am newbie to RISCWatch and debugging using JTAG interface .I want to debug
Linux Kernel on target board
using jtag interface provided on board.
To debug 970MP dual core ppc processor on traget board, I installed
RISCWatch software on my window host.
My Setup:
----------
Host <--(over ethernet)--> RISCWatch 13H6423 <--(jtag interface)--> 970MP
Processor
I am able to detect two core on target 970MP processor but it shows both
cores as `UNKNOWN` . I have no idea,
why riscwatch shows up status of both cores as UNKNOWN?
I would like to mention:
-------------------------
1) After attaching JTAG cable & switching on riscwatch box, powered cycle
was done on the target board
and restart RISCWatch. But still core status is shown `UNKNOWN`
2) For PVR value 0x00440101, I used `REV = 1' in rwppc.env file. Correct us
if I am wrong.
3) I am able to ping RISCWatch 13H6423 from host system.
4) When I reset target board, target status changes from "UNKNOWN to HALTED"
and "HALTED to UNKNOWN"
I noticed that PVR register value is 0x00440101. I am not sure if this
confirms that revision of the processor(970mp) is 1.
Please find the rwppc.env file (C:\Program Files\RISCWatch\rwppc.env) that I
configured:
----------------------------------------------------------------------------------------
PROC = 970MP
REV = 1
TARGET_TYPE = jtag_eth
TARGET_NAME = 192.168.10.5
RWPPC_DIR = .

Thanks,
I've seen issues with my PPC box and function graph, but the bugs were
also caused by other changes. I'll boot up my PPC64 box and see if
I see the same issues you have.

It's legacy because there are no in-tree users anymore. Nowadays
we're trying to pass all needed information via OF, and we're
trying to avoid ugly platform-dependant hacks. Your SPI scheme
can be easily described via OF, but sure, it's hard to implement
it with the current SPI/OF subsystem.

I'm not the right person to ask. I can only express my opinions.
The maintainer make final decision.
But if you ask for my opinion, I don't think that they should stay
unless we'll see a user in the mainline.

Yes and no. Yes, it has "regressed" for out-of-tree code, and no,
I don't feel sorry about that. :-)

ehh, it was working until you made it OF only. Why do call the native

This is probably needed to support most SPI users out there, but until
such framework is in place I think the native methods need to stay, rig=

As is now, SPI has regressed w.r.t earlier releases.

* proper way to reserve a chunk of memory at the top of the kernel?
From: Chris Friesen @ 2009-07-14 21:18 UTC (permalink / raw)
To: linuxppc-dev, Linux kernel
I have a powerpc board with 512BM of memory. The BIOS has a chunk of
memory at the top end of physical memory which it does not zero out over
a reboot.
What's the proper way to tell linux that this chunk of physical memory
should be ignored (so that we can access it later without worrying that
Linux will try to allocate it)? Should I be calling
lmb_reserve(lmb_end_of_DRAM() - size, size);
in early_reserve_mem() or is there a better mechanism?
For comparison, in an older kernel this was done in set_phys_avail(), by
calling mem_pieces_remove(&phys_avail, total_lowmem - size, size, 1);
Thanks,
Chris

* Support for PCI Express reset type in EEH
From: Mike Mason @ 2009-07-14 18:35 UTC (permalink / raw)
To: linuxppc-dev, linux-pci, Paul Mackerras, benh, linasvepstas; +Cc: Richard Lary
By default, EEH does what's known as a "hot reset" during error recovery of a PCI Express device. We've found a case where the device needs a "fundamental reset" to recover properly. The current PCI error recovery and EEH frameworks do not support this distinction.
The attached patch (courtesy of Richard Lary) implements a reset type callback that can be used to determine what type of reset a device requires. It is backwards compatible with all other drivers that implement PCI error recovery callbacks. Only drivers that require a fundamental reset need to be changed. So far we're only aware of one driver that has the requirement (qla2xxx). The patch touches mostly EEH and pseries code, but does require a couple of minor additions to the overall PCI error recovery framework.

It doesn't cause the problem, it only exposes it. And, of course,

* [PATCH v2] fs_enet/mii-fec.c: fix MII speed calculation
From: Wolfgang Denk @ 2009-07-14 13:42 UTC (permalink / raw)
To: linuxppc-dev; +Cc: netdev, Wolfgang Denk
In-Reply-To: <1244751543-21977-2-git-send-email-wd@denx.de>
The MII speed calculation was based on the CPU clock (ppc_proc_freq),
but for MPC512x we must use the bus clock instead.
This patch makes it use the correct clock and makes sure we don't
clobber reserved bits in the MII_SPEED register.

Cc: Grant Likely <grant.likely@secretlab.ca>

---
Note 1: This patch is a rewrite of a previous posting:
http://patchwork.ozlabs.org/patch/28584/
Note 2: Function mpc5xxx_get_mii_speed() was introduced for re-use
in a later patch to drivers/net/fec_mpc52xx.c and
drivers/net/fec_mpc52xx_phy.c, which also contain code to
calculate the MII speed without taking care to check for
overflow or to write only the bits that belong to the
MII_SPEED field when setting the MII speed.

* Re: [patch 1/3] powerpc: Move 64bit VDSO to improve context switch performance
From: Anton Blanchard @ 2009-07-14 7:38 UTC (permalink / raw)

Hi Ben,
> Don't we lose randomization ? Or do we randomize the whole mem map
> nowadays ?
The start of the top down mmap region is randomized, so the VDSO will be in a
different position each time. A quick example:
run 1:
fffb01f6000-fffb01f9000 r-xp 00000000 00:00 0 [vdso]
fffb01f9000-fffb01fa000 r--p 00027000 08:06 4333852 /lib64/ld-2.9.so
fffb01fa000-fffb01fd000 rw-p 00028000 08:06 4333852 /lib64/ld-2.9.so
fffb01fd000-fffb01fe000 rw-p 00000000 00:00 0
ffff7c6f000-ffff7c84000 rw-p 00000000 00:00 0 [stack]
run 2:
fff9a094000-fff9a097000 r-xp 00000000 00:00 0 [vdso]
fff9a097000-fff9a098000 r--p 00027000 08:06 4333852 /lib64/ld-2.9.so
fff9a098000-fff9a09b000 rw-p 00028000 08:06 4333852 /lib64/ld-2.9.so
fff9a09b000-fff9a09c000 rw-p 00000000 00:00 0
fffea0a6000-fffea0bb000 rw-p 00000000 00:00 0 [stack]
You will notice we aren't randomising each mmap, so the relative offset
between ld.so and the vdso will be consistent. I just checked and it
looks like x86 does the same.
It might make sense to add a small amount of randomness between mmaps
on both x86 and PowerPC, at least for 64bit applications where we have
enough address space.

* [patch 2/3] powerpc: Rearrange SLB preload code
From: Anton Blanchard @ 2009-07-14 6:53 UTC (permalink / raw)
To: benh; +Cc: linuxppc-dev
In-Reply-To: <20090714065350.659537380@samba.org>
With the new top down layout it is likely that the pc and stack will be in the
same segment, because the pc is most likely in a library allocated via a top
down mmap. Right now we bail out early if these segments match.
Rearrange the SLB preload code to sanity check all SLB preload addresses
are not in the kernel, then check all addresses for conflicts.

TASK_UNMAPPED_BASE is not used with the new top down mmap layout. We can
reuse this preload slot by loading in the segment at 0x10000000, where almost
all PowerPC binaries are linked at.
On a microbenchmark that bounces a token between two 64bit processes over pipes
and calls gettimeofday each iteration (to access the VDSO), both the 32bit and
64bit context switch rate improves (tested on a 4GHz POWER6):

On 64bit applications the VDSO is the only thing in segment 0. Since the VDSO
is position independent we can remove the hint and let get_unmapped_area pick
an area. This will mean the vdso will be near other mmaps and will share

On a microbenchmark that bounces a token between two 64bit processes over pipes
and calls gettimeofday each iteration (to access the VDSO), our context switch
rate goes from 268k to 277k ctx switches/sec (tested on a 4GHz POWER6).

Oops, I overlooked this. However, as you said, this is not a problem
with the current code.

I think that it's IA64's optimization (it's a NULL function on X86
like POWERPC). It's defined in arch/ia64/mm/init.c. Looks like POWERPC
could use this optimization, I guess.
dma_mark_clean() just modifies the page flag (what it needs is struct
page) so I think that we can make it take a paddr.

Ok, I'll do.
