I'm trying to fix some of the AX25 code in the 2.6 kernel and traced down
a problem to the use of a char var which was being assigned
the value of -1. On x86 when the var was compared to -1 it succeded but
on PPC it failed. So I tried a simple test:
main()
{
char atest;
atest=-1;
printf("%i,%X\n",atest,atest);
}
With GCC 3.3.5 on 2.6.14-rc1 x86 I get:
./atest
-1,FFFFFFFF
With GCC 3.3.5 on 2.6.14-rc1 PPC I get:
./atest
255,FF
If I change the declaration of atest to a signed char on PPC I get the
same result as x86.
Does this mean the char in x86 is signed and in PPC it's unsigned?
Has it always been thus?

Did you mention in the past you have a custom boot loader? Is this
something
other than the PlanetCore boot rom?

I doubt they made any modifications to the generic driver. The only
thing
they may have done is added some board control register/GPIO to enable
the RS-232 transceiver. If you don't have their board initialization
functions,
though, this would be useful.

What about just trying to boot the new kernel from PlanetCore boot rom?
Of course, if you are doing your own boot rom and have a board to bring
up,
you should have invested in something like a BDI2000 long ago because
it will
have paid for itself many times over by the time you are done :-) It
would have
also allowed you to debug this problem rather quickly.
You are going to have to investigate your processor state prior to
calling
Linux (HIDx registers, cache and MMU state, SIU configuration, etc) to
see
how it differs from what PlanetCore does. There are lots and lots of
options
on these processors, and one bit in one configuration register that is
incorrect can cause lots of grief.

introduction of a user specificable value of HZ (in include/asm-ppc/parm.h)=

I used a value of 250 while the former default was 1000. Setting it back to=

1000 makes the clock tick right again.
Is the CONFIG_HZ known to be broken on PPC ?

You can try the tool which I wrote to test SPI-connected MMC card and
different I2C chips (EEPROMs, temperature sensors, etc.). As it was
discussed on the list, our implementation of SPI uses I2C infrastructure
so the same tool works for both I2C and SPI. I attached to this mail the
source, brief documentation, and some examples.

Using i2cspi
i2cspi takes I2C/SPI-related commands from a file (or standard input),
executes them and writes output read from the I2C/SPI peripherals to a
file (or standard output).
To run i2cspi, type the following:
i2cspi [-b devname] [-i file] [-o file] [-r] slaveadr
where
slaveadr is the address of the I2C peripheral to be accessed.
Optional parameters (where supplied) are used as follows:
-b devname selects the bus; "devname" is the full device name of
the I2C bus. Default is /dev/i2c-0.
-i file sets the input file to "file". If not specified, the
standard input is used.
-o file sets the output file to "file". If not specified, the
standard output is used.
-r specifies raw mode (binary data is dumped raw to output
instead of formatted by printf via %x). Rarely required.
i2cspi input file format
The input file for i2cspi is a string of I2C/SPI commands entered as
ASCII text. All white-space (including carriage-returns, tabs, etc) are
taken as delimiters and otherwise ignored, so the commands may be
entered line-by-line or on a single line separated by white space. The
command letters do not need delimiters - they may appear immediately
before or after a numeric value (x1 is equivalent to x 1).
The following commands may be used in i2cspi:
r n read n (decimal number) bytes from the slave. In typical
cases, this is rarely used since a write usually needs
to precede a read operation.
w seq write a sequence of hex bytes to the peripheral. Each
byte is represented by two hex characters; the sequence
is terminated by white space. For most SPI peripherals,
this command is only rarely used.
x flags seq [p n] this is the data exchange operation and is the
most commonly used SPI operation. Data is
written and read to the peripheral in
parallel. Note that the same number of clocks
are required for both read and write operation,
so you need to pad any write sequence to the
length of the read sequence that you wish to
read. Parameters for the 'x' command are as
follows:
flags are a hex number and as defined in the Linux I2C
infrastructure. The two flags of relevance are:
0x0001 - read data returning from the peripheral in parallel to
writing
0x4000 - do not de-select the peripheral after the operation
has completed
seq is a sequence of hex bytes (2 characters per byte). If
[p n] is specified, the sequence is repeated 'n' (decimal)
times. This is useful for long sequences.
u EXECUTE ALL PRECEDING COMMANDS. DO NOT FORGET THE 'U' COMMANDS
SINCE WITHOUT IT NOTHING WILL HAPPEN! IN PARTICULAR, WE DO NOT
ASSUME 'U' AT EOF, SO MAKE SURE YOUR INPUT FILE ENDS WITH A 'U'
COMMAND.

Well, at this point, it only really concerns nvidia and ati's and their
respective firmwares seem to expose some properties a bit differently...
The radeon code would probably work for nvidia though as I'm not trying
to get the connector type for nvidiafb yet, but if I ever try, it seems
the stuff is a bit different.
I'd say let's keep them separate for now, I may put them in a common
place some day ..

Ok, if you confirm it doesn't seem to do any regression on other
hardware (I don't have any other nvidia hw to test with), I'd like it
upstream asap (probably too late for 2.6.14 though).

(This version removes a useless bit that slipped in the previous one)
This patch fixes a couple of things in nvidiafb:
- The code for retreiving the mode from Open Firmware was broken. It
would crash at boot and was copied from the old rivafb code that didn't
work very well (I'll update rivafb too one of these days).
- The mode setting code produced weird results on the 5200 card in the
iMac G5 here. X "nv" code works fine though. After comparing them, I
found out that we aren't really manipulating some VGA bits the same way
and X code seemed better, so I slightly changed the mode setting to do
the same and that fixed the problem. (The display was strangely shifted
with garbage in the margin but not on all lines, and not in bpp 32)

* [PATCH] nvidiafb: PPC & mode setting fixes
From: Benjamin Herrenschmidt @ 2005-10-02 3:57 UTC (permalink / raw)
To: Antonino A. Daplas
Cc: linuxppc-dev list, linux-fbdev-devel, Linux Kernel list
Hi !
This patch fixes a couple of things in nvidiafb:
- The code for retreiving the mode from Open Firmware was broken. It
would crash at boot and was copied from the old rivafb code that didn't
work very well (I'll update rivafb too one of these days).
- The mode setting code produced weird results on the 5200 card in the
iMac G5 here. X "nv" code works fine though. After comparing them, I
found out that we aren't really manipulating some VGA bits the same way
and X code seemed better, so I slightly changed the mode setting to do
the same and that fixed the problem. (The display was strangely shifted
with garbage in the margin but not on all lines, and not in bpp 32)

It is okay, and putting those symbol definitions
outside the section definition (like the ppc32
linker script used to do) can be wrong even, for
example, when the output sections need extra
alignment.

Indeed.
> Why doesn't this work for you?
The code works fine. The U and X have no effect at all,
though; they require a memory operand to do anything,
and __do_in_asm() c.q. __do_out_asm() take a register
input. It would be better if __do_in_asm() would say
"m" (*(port + ___IO_BASE))
where it now says
"r" (port + ___IO_BASE)
and keep the %U %X stuff (and similarly for __do_out_asm()
of course).

* clock skew on B/W G3

Hi,
something between 2.6.13-git4 and 2.6.14-git5 makes my clock running ~20%
slower. This problem still exists in current kernel versions. Sorry for
reporting so late, but I hope it would go away while time passes...
As the subject says I have blue/white Apple G3/400. My config I attached.
Thanks
Marc

Just in case anyone is wondering, the new patchset has been built for (my
configs) pSeries, iSeries, g5, ARCH=ppc, ARCH=powerpc ppc32 pmac,
ARCH=powerpc iSeries and I have booted the ARCH=powerpc iSeries kernel.

OK, thanks for keeping me honest :-) Here is new versions of patches 6
and 7 (all the rest are the same as before).
---------------
Use idle_power4.S from ppc64 as we are not going to support
32 bit power4 in the merged tree.
Merge ppc64 traps.c into powerpc traps.c:
use ppc64 versions of exception routine names
(as they don't have StudlyCaps)
make all the versions if die() have the same
prototype

* [PATCH] ppc32: Add new iBook 12" to PowerMac models table
From: Sven Henkel @ 2005-10-01 7:57 UTC (permalink / raw)
To: benh, linuxppc-dev; +Cc: linux-kernel
Hi,
this patch adds the new iBook G4 (manufactured after July 2005) to the PowerMac
models table. The model name (PowerBook6,7) is taken from a 12" iBook, I
don't know if it also matches the 14" version. The patch applies to a vanilla
2.6.13.2 kernel.
Ciao,
Sven

Yes I'm sure the code in Linux is right. It may be missing some
initialisation it depends on, but anyway.
My board is an Embedded Planet EP8248 that came with a pre-installed
version of Linux 2.4. That version works ok, though I don't know what
modifications were made to the kernel. The source wasn't included...
Currently I boot with PlanetCore, load my own boot loader (I'm going to
use it exclusively when my own custom board based on 8247 comes out) via
tftp, and start the most recent kernel.org kenel from it.

Tolunay, thank you so much for providing me this
closest stuff. It can just work right on DS1337 on
my board. I just added alarm register operation in it.
After finshing LM75 porting on this board, I'd like
to try to get a common i2c utility just like "imd"
and "imm" in u-boot.
Have a nice weekend,
Sam

I happen to have a LM75 on this board. Your hints
remind me to follow the lm-sensors list to find
something special on this point as well.
Thanks a lot,

In that case, what is the advantage of having two traps*.c files in
arch/powerpc/kernel instead of having them in arch/ppc*/kernel?

My first attempt at the merge was a real mess and a right pain, so I put
the two files in as a compromise. However, I have made another attempt
and ,although it took a while, it seems to be going ok. How about we put
the two in for now (as that will allow the merge of more platforms to
continue) and I will supply a further patch in a few days that combines
the two trapsxx.c files?

* [PATCH] pmac: fix cpufreq for old tipb 550Mhz
From: Benjamin Herrenschmidt @ 2005-09-30 23:21 UTC (permalink / raw)
To: Linus Torvalds; +Cc: Andrew Morton, linuxppc-dev list
The old 550Mhz titanium powerbook can switch to a lower frequency
(500Mhz). A user has been repeately reporting overtemp conditions on his
machine at high speed so this simple patch adds support to PowerMac
cpufreq for this machine. The difference in frequency isn't big but seem
enough to fix that user's problems. The patch has been around for some
time now and doesn't seem to cause any problem, so I suppose it could go
in now.

I really dont like the ideal of splitting up traps.c into traps32.c
and traps64.c. This defeats the purpose of the merge. I expect that
a significant portion of traps.c is common (or can be made to be)
between all powerpc's.

* where should readb based/platform specific memcpy_fromio() be?
From: Yasushi SHOJI @ 2005-09-30 20:02 UTC (permalink / raw)
To: linuxppc-dev
Hello,
I'd like to add a variant of memcpy_fromio() for 16bit bus. In-tree
implementations seem to me that most, if not all, arch have either
readb() or memcpy() based mempy_fromio.
powerpc doesn't currently have readb() based. I assume that means all
ppc boards are 32bit clean.
if I'd like merge this readb() based or optimized for 16bit bus
version, where should I put it? obviously I have to add ifdef in
include/asm-ppc/io.h, but should I do either:
- add extern in io.h and body under platform/..../xxxx.c
- add extern in io.h and body under arch/ppc/lib/io.c
- add static inline version in io.h
- add static inline version in platform/..../xxxxx.h which is
included from asm-ppc/io.h
regards,

I just built an 8250. 8260, and 8270 from a very recent 2.6 tree today
and they
all worked fine. They all had different serial port configurations
(SMC1, SCC1
and SCC2). Two were u-boot and one was a proprietary boot rom.
So, the "problem" seems to be related to something unique with your
system.

This is code that has existed for many years in Linux and appears to
continue
to work fine. We need to identify what is causing the problem in your
environment, not look for some hack around it.
Thanks.
