Good point. I just checked the same test, but reading instead of writing. Same
result, no cache detected.
I know how to change cache policy in u-boot, but does the kernel change that?
If so, where?

I have done different methods (lots of code),
- as a test just setting the memory, with memset,
- custom copying word by word, flushing the cache while going,
- flushing the cache afterwards,
the results are not always what I excected, the memset works if I don't set to
much like from 0x0 – 0x200. The copying would be the complete block.

No the task maybe not, but the method could be,

I have seen them, and my conclusion is: Your kernel was working ok, while
mine, a newer one, is broken.
As you can see in the other e-mail I just posted (replying to Marcelo), at
least the CPU cache seems to be disabled. Might this have something to do
with processor model (mis-) identification?
I had to apply the "ppc_sys: do not BUG if system ID is unknown" patch from
Marcelo Tosatti a few days back in order to be able to boot in the first
place. I had a look at ppc_sys system identification for 8xx and it looked a
little bit nonsensical to me, since all 8xx report the same ID. Maybe the
intention was to set the ID "by hand" in board support and setup.
Problem is: there is still no real board-support infrastructure for mpc8xx,
like there is for mpc82xx for example. What are the plans for 8xx? Should I
try to emulate what others have done for some PQ2 platforms, i.e. create a
arch/ppc/platforms/myplatform.c file and implement board_init()?

Ok, done that... no change.
I don't get any of those debug messages, so I guess that was not the problem.
I have made another test in the meantime, trying to check if cache is working.
The test is pretty simple: see how fast I can fill a block of memory whose
size is increasing by a power of two. You should expect to see a step-like
decrease in speed when surpassing the size of the data cache (4kbyte).
The results are very suspicious:
kernel-2.4:
Memsize 512 : 39.342773 Mbyte/s
Memsize 1024 : 41.871094 Mbyte/s
Memsize 2048 : 43.212891 Mbyte/s
Memsize 4096 : 40.117188 Mbyte/s
Memsize 8192 : 28.148438 Mbyte/s
Memsize 16384 : 28.484375 Mbyte/s
Memsize 32768 : 28.656250 Mbyte/s
Memsize 65536 : 28.687500 Mbyte/s
This looks quite healthy: above 4kbyte we see a clear drop in performance, so
we just learned that our data-cache is most probably 4kbyte in size, wow!
Kernel-2.6:
Memsize 512 : 21.033691 Mbyte/s
Memsize 1024 : 22.047852 Mbyte/s
Memsize 2048 : 22.601562 Mbyte/s
Memsize 4096 : 22.882812 Mbyte/s
Memsize 8192 : 23.007812 Mbyte/s
Memsize 16384 : 23.093750 Mbyte/s
Memsize 32768 : 23.125000 Mbyte/s
Memsize 65536 : 23.125000 Mbyte/s
No, sir, no cache detected !
Where do I have to look now?

Following your advice I've created a sourceforge project for the USB
drivers for mpc82xx. For now I've posted there only 2.6 version. As for
driver for 2.4, it would be better if it'll be posted by someone who's

Yes. There are some gotchas with newer pcmcia/cardbus flash cards.
For instance, Silicon Systems devices claim to support IORDY, but don't,
which results in a system hang. I imagine that the same kind of things
will show up in newer CF devices, although I think that CF can't support
DMA.
It also depends upon how you interface CF: via an IDE controller, or
via a cardbus interface.
I expect to have a git tree with stuff available soon.

So, you have two MPC852Ts on a board, and they are cross-wired such
that you send HDLC between them using the scc, and you want to:
(my question):
a) you want to reprogram the scc's to send ethernet frames?
b) you want to encapsulate ethernet frames in HDLC?
c) you want to connect the two 852s using some kind of IP
networking?
HDLC is commonly used on T1 links, and one method puts frames that
essentially look like ethernet frames over it.

* please pull the powerpc-merge.git tree
From: Paul Mackerras @ 2005-10-31 4:23 UTC (permalink / raw)
To: torvalds; +Cc: linuxppc-dev, linuxppc64-dev
Linus,
Please do a pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc-merge.git
to get a ppc/ppc64/powerpc update.
We are now a considerable way through the ppc/ppc64 -> powerpc merge.
It is now possible to build kernels for powermac, pSeries, iSeries and
maple with ARCH=powerpc, and for powermac, both 32-bit and 64-bit
build and run. I have not yet put in the patch that makes it default
to ARCH=powerpc if uname -m gives ppc or ppc64, though.
Andrew sent me all of the patches he had queued that affected ppc and
ppc64, and I have merged in most of them (the rest I am discussing
with their authors).
Diffstat and shortlog follow.
Thanks,
Paul.

Well, you typically do this with the MMU disabled and making sure you
don't take an exception while copying over them...

* exception vectors

In-Reply-To: <1130645036.29054.229.camel@gaston>
Hi all,
I am trying to overwrite the exception vector space of an ibook G4 :).
I have set up (for every exception) a small piece of code, that's a prefix of a
handler to be called. My problem is, that writing the “small” chunks of code to
the exception vector space gives no problem(so it seams) but writing all the
pieces of code as one chunk gives a exception [dsi, dsisr 0x42000000], this
indicates a store problem.
I have tried different modes of copying, mmu on/off, also chanced the WING bit,
switched the exception prefix on.
I don't believe putting the exception vectors to there “place” one by one is the
right way, in the Linux kernel the kernel get relocated and the code comes into
place. I have taken this as an example, unfortunately to to result :(..
- Am I overlooking something?
- Is the a “standard way” to overwrite the exception vector space of a powerpc?
ThankZ,

* PowerPC PVR version bug (G4 etc.)
From: Matt Sealey @ 2005-10-30 23:38 UTC (permalink / raw)
To: linuxppc-dev
There is a small, innocuous but annoying processor version reporting bug.
/proc/cpuinfo for my 1Ghz 7447 says
revision : 0.1 (pvr 8002 0101)
In fact the processor is version 1.1. You can see it is properly encoded
but the macro used to decode it is (in asm-ppc/reg.h):
#define PVR_MAJ(pvr) (((pvr) >> 4) & 0xF) /* Major revision field */
#define PVR_MIN(pvr) (((pvr) >> 0) & 0xF) /* Minor revision field */
When Freescale processors are detected, it sets maj and min to the results
of these macros.
Then it prints:
seq_printf(m, "revision\t: %hd.%hd (pvr %04x %04x)\n",
maj, min, PVR_VER(pvr), PVR_REV(pvr));
Obviously for standalone Freescale processors, at least this is plain wrong;
the correct shift is >> 8 for the major revision field. There is a comment
above the PVR_ macros that this is an IBM encoding scheme, so..
Any chance of a minor fix for this? It will affect every G4 processor ever
made which is a lot of chips in a lot of machines, and for systems that can
use a 7447, 7447A, 7448 there are two or three PVRs (7448 especially which
has a 1.1 and a 2.1 version) that can produce a 0.1 result which may cause
problems if someone accidentally decides to grep that string and ignore the
PVR.
As I said it's innocuous but it's there.
Thanks :)

Yeah, that's what it does now too, if it can't find anything in the
"right" part of the table, it'll try the other. So other devices would
use the same section if the "regular" table got full.

Yup, that would be useful with some 3rd party bridges that don't have an

No real need to split permanently... the search could be restricted to a

Not a problem, I was just thinking out loud. IOMMU pressure might be
higher on these systems than the average one, but there should still be
enough room.

The non-iommu case might want to do that for other devices as well,
i.e. 32-bit limited ones on 64-bit machines.

Yep, the table is already split once, and I'm not sure in retrospect how
useful that split was anyway, it can maybe go away. Switching it around

Ugh ?
What is the problem precisely ? This is just a dodgy workaround for an
unexplained problem. Normally, the kenrel _WILL_ cause a tlb flush after
manipulating a PTE.

Euh... I think that's exactly what we do :) We _unmap_ the 16Mb page
from the linear mapping, and we remap a part of it using ioremap() (thus
as 4k pages) in the DART driver... The remaining bits are thus not
mapped at all, there is no problem using __ioremap() to get a cacheable
mapping there.

Why would this be a problem ? The infiniband driver would hopefully have
a sane dma_mask, and thus it's mapping requests wouldn't hit the swiotlb
code path.

Yes, though that's not strictly necessary. The dma_mask should be enough
to tell us wether to use the normal code path or the swiotlb one. So if
swiotlb is enabled, it could just be added to the normal code path for
the non-iommu case. For the iommu case, I'm not sure. I think we don't
need bounce buffering. I could fairly easily have the DART code limit
allocations to a given DMA mask. The TCE one may have more issues since
the DMA window of a given slot may not fit the requirements, but in that
case, it's probably just a matter of failing all mapping requests.

Keep in mind that those 16MB are cache inhibited. Not sure you'd want
that for the bounce buffer. And you can't map the same page as cacheable
or you'll end up in inconsistent state. I guess you could remap the 14MB
as 4K cacheable pages somewhere else.

Some of the Infiniband and Myrinet adapters like to map as much as they
possibly can. I'm not sure what the likeliness of them being used on a
machine at the same time as one of these crippled devices is though.
Besides, they usually back off a bit from allocating everything in the
system, so there should be some room.

Sounds reasonable to me too. I guess time will tell how hairy it gets,
implementation-wise. The implementation could also be nicely abstracted
away and isolated thanks to Stephen's per-device-dma-ops stuff.
