* [PATCH] powerpc: Use the ibm,pa-features property where available
From: Paul Mackerras @ 2006-05-01 4:04 UTC (permalink / raw)
To: will_schmidt, linuxppc-dev
Forthcoming IBM machines will have a "ibm,pa-features" property on CPU
nodes, that contains bits indicating which optional architecture
features are implemented by the CPU. This adds code to use the
property, if present, to update our CPU feature bitmaps.
This is based on a patch by Will Schmidt <will_schmidt@vnet.ibm.com>
Signed-off-by: Paul Mackerras <paulus@samba.org>
---
At the moment we're looking at all the ibm,pa-features properties and
processing them all... Maybe we should only look at the one for the
boot cpu.

OK, I actually tried this and it works! :-(
I traced the code path and it turns out that the place we check for the
-100 (in do_path_lookup), the compiler has used a cmpwi instruction and so
ignores the top 32 bits. Thus we get away with the ABI abuse!

* [RFC/PATCH 1/4] powerpc: Register udbg_console for early debugging
From: Michael Ellerman @ 2006-05-01 0:53 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
In-Reply-To: <1146444821.660434.518701003988.qpush@concordia>
If we have early debugging enabled, then register the udbg console, so we
can use printk rather than udbg_printf.
I'm not sure about the jiggering with console_loglevel, but without it you
need to add "loglevel=8" to the command line, which I think might annoy people.

* [RFC/PATCH 0/4] powerpc: Use pr_debug() for debugging
From: Michael Ellerman @ 2006-05-01 0:53 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
Currently we have a macro called DBG() defined in most files in arch/powerpc,
which is used to do debugging printks.
In some files DBG evaluates to printk() and in others it becomes udbg_printf(),
but there doesn't seem to be any logic to explain why it's one or the other.
In fact in some files it'd be nice if it was both, so you could have early
debugging (udbg_printf), but then have things hit the dmesg buffer later (via
printk).
Using udbg_printf() in general is suboptimal IMHO because it bypasses the
printk buffer, so if you miss the messages on the screen you can't go back and
see them in dmesg.
So this series of patches rejiggers things so that we register the udbg
console really early, and therefore can always use printk. It then goes on to
change all the home spun DBG() macros into pr_debug() calls, from
include/linux/kernel.h
I haven't tested this extensively because I wanted to gauge people's reaction
first. It "works" on pSeries LPAR, and iSeries, but I haven't tested on 32-bit,
and I don't know that code well so I'm all ears on that.

* windfarm for PM72/PM73/RM31
From: Robin H. Johnson @ 2006-05-01 0:27 UTC (permalink / raw)
To: linuxppc-dev
[-- Attachment #1: Type: text/plain, Size: 1193 bytes --]
Hi,
I'm working on writing a windfarm driver for the PM72/PM73/RM31 boxes,
amongst some other windfarm work I'm doing, and I have a few quick
notes/questions:
Process so far/TODO list:
- I've got the ds1775 and max6690 chips returning all of their data on
PowerMac11,2 and PowerMac7,3. I need to change the detection code for the
max6690 sub-nodes (it has both internal and external temps) as they
don't exist on PM72.
- Need to write windfarm sensor drivers for: ds1631, ad7417, lm87
- Flesh out my windfarm_pm72 more - it's based on the therm_pm72
constants and the pm112 module for now, completely untested until I
have the sensors and controllers hooked up.
Questions:
1. Message naming consistancy - there are a number of printk/DBG
statements that seem to flip randomly between using a prefix of
'windfarm:' or 'wf:', and then some that omit it entirely.
Any consensus on which one is preferred?
2. Could somebody please send me a tarball of /proc/device-tree/ from a
RackMac3,1 unit? I've got the data for PM72/73 already.

Try mkdirat. openat has a compat wrapper that has the dfd paramater
declared as a unsigned int and passes it to sys_openat, whose first
paramter is decalred to be int, so the sign extension gets done.

* [PATCH] powermac: U4 DART improvements
From: Olof Johansson @ 2006-04-30 19:14 UTC (permalink / raw)
To: linuxppc-dev; +Cc: paulus
Hi,
Jimi Xenidis posted Xen drivers that do individual TLB shootdowns on U4
DART on Friday:
http://lists.xensource.com/archives/html/xen-ppc-devel/2006-04/msg00085.html
We haven't been able to do it before since we didn't know any register
layouts past what Darwin used. So now we can implement individual
teardown.
This boots happily on my quad at home, but I'd appreciate more testing
by people who have U4-based machines. Also, if someone feels like doing
some benchmarking to find the breakeven point between full invalidation
and individual shootdowns, that'd be cool.
Patch below.
---
Implement single-entry TLB invalidations in the U4 DART.
At some point it makes more sense to invalidate the whole TLB instead of
individual entries. I picked a breakpoint at 32 entries, but it might make
sense to move it if benchmarking shows it to be too high or low.

Hi Dan,
Shame on me! I screwed up.
David, can you please try the following patch on top of vanilla v2.6.16?
The large TLB change introduced in v2.6.16 (which is broken as is for
configurations without CPU6 errata enabled as Dan noted) should boost
performance significantly, so you might want to rerun the lmbench
tests...

Folks,
The v2.4 patch acceptance policy has been shifting gradually from
"accept new features" to "critical fixes only", and at this point in
time the goal is to have a minimal amount of modifications as possible.
There should be no need for major patch reworking with reference to new
v2.4 releases.
Willy Tarreau created a repository of useful v2.4 patches for this sort
of situations. Stephen, Eugene, I think the 405GPr patches are good candidates.
http://w.ods.org/linux/kernel/2.4/lkup/hardware.html
Of course that it would be incredibly better for everyone to be happy with
v2.6. I see a lot of embedded users complaining about v2.6.
Cyclades (my former employer) has been using v2.6 in production
environments with 48MHz MPC855T PPC's with no problems at all (actually,
it is faster in certain key situations). This boxes have 128MB, which is
can be considered large, but still, no major problems have been seen in
_several_ different v2.6 versions.

The docs (for example, "CBE_Architecture_v10.pdf") say 2.02. One
more reason
to not use those arch version numbers.

Oh, and it also has some extensions that are supposed to be part of later
powerpc architecture releases (CBEA, appendix E):
• Mediated interrupt
• Multiple concurrent large pages
• Add TL (TLB load control) bit to logical-partitioning control register
(LPCR) for software versus hardware load of TLB
• Change tlbie<l> of large page to always invalidate ERAT
• Hypervisor SPRs no longer readable when HV equals 0
Do we know which ones of these made it into 2.05?

The Cell Broadband Engine Architecture in theory is 2.03 and also mandates
some of the extensions that are optional in there.
The relevant sections in the specs are:
| 4.1.1 Optional Features in PowerPC Architecture, Book I (Required for
| CBEA)
| The following facilities and instructions are considered optional in
| the PowerPC Architecture, but are required for the PPE by the CBEA
| user mode environment.
| • Floating reciprocal estimate single A-form (fres)
| • Floating reciprocal square-root estimate A-form (frsqte)
| • Vector/SIMD multimedia extension
| Note: The optional PowerPC floating-point instructions that are
| mandatory in the CBEA are needed for the application space targeted
| by the CBEA.
|
| 4.1.3 Optional Features in PowerPC Architecture, Book II (Required
| for CBEA)
| The following facilities and instructions are considered optional
| in the PowerPC Architecture, but are required in the CBEA.
| • Data cache block touch X-form (dcbt)
| This is an optional version of dcbt that permits a program to
| provide a hint that a sequence of data cache blocks is likely
| to be needed soon.
| Book II describes these facilities and instructions.
I believe the actual implementation is missing one of the mandatory
features of 2.03 that was not in 2.02 though.

* Large Page Support, 2.6 kernel , PPC440
From: moris dong @ 2006-04-30 8:17 UTC (permalink / raw)
To: linuxppc-dev
Friends,
My PPC440 (32bit) MMU supports multiple page sizes.
For the default 4K pages, my 2.6.11 kernel compiles and boots just fine.
I want to re-build it with large pages, to improve my application
performance.
I tried modifying PAGE_SHIFT in "page.h" to 13 (8K pages) and re-build my
kernel.
Compilation worked out fine, but my kernel does NOT boot, nor it prints
anything to the console.
Has anyone successfully compiled & booted a 2.6 kernel for PPC440 with pages
larger than 4K ?
What am I doing wrong ?
Thanks a lot.

Below is definitely not 2.6.17 material, so for the 2.6.18 queue:

Either constant or comment is wrong, I'm guessing it's comment since the

Less talk, more patches. 2.6.18 material.
Btw, looks like glibc duplicates the definitions instead of includes them,
but let's be nice and keep them anyway. Besides, they got the ISA
version to processor mappings wrong in their comments.
---
Rename PPC_FEATURE_POWER.* to be signify the base architecture versions
instead. Keep the old names around since they're defined outside of
__KERNEL__.
If POWER5 is 2.02 (last public version), and POWER6 is 2.05, then POWER5+
should be 2.03 or 2.04. Not sure what fills in the hole, but I took a
guess that 5+ is 2.03.

Are there any userspace-visible differences between 2.00 and 2.01?

It's actually about an even tradeoff between the two. We run the risk
of running out of bits eventually no matter what, and as long as it's
blindingly clear and well stated that it does not imply any optional
features, then it doesn't matter. This puts the burden on userspace
developers to know which features are optional, not just what works on
their POWER6 lab machine, etc.

We already have SMT, ICACHE_SNOOP and ALTIVEC feature bits, so it probably
makes sense to stay in the ARCH_2_05 direction. Unfortunately it might
be tricky to rename the old defines now due to userland exposure.
I guess Cell breaks all this logic though. Which PPC base version does
it implement?
