* smc2 without hw handshake
From: Antonio Di Bacco @ 2006-06-13 19:51 UTC (permalink / raw)
  To: linuxppc-embedded

Hi all,

I'm using the SMC2 serial device of MPC880 without using hardware handshake. I 
use only tx and rx at a speed of 9600. Could it work? The driver I use is 
included in linux 2.4.25 from denx.

Bye,
Antonio.

* No ttyS device at I/O port 0xfe004500 for console
From: Alex Zeffertt @ 2006-06-13 16:48 UTC (permalink / raw)
  To: linuxppc-embedded

Hi list,

I'm trying to boot a linux-2.6.11 kernel on a MPC83xx based board.  Through
some experimentation I have found I need "console=uart,io,0xfe004500"
in the kernel command line in order to get any output over the serial
port.

Half way through initialisation the kernel appears to swap from its "early"
8250 serial driver to a "full" 8250 serial driver.  At this point it prints
"No ttyS device at I/O port 0xfe004500 for console" and there is no
further output.

Does anyone have any idea what I may be doing wrong?

BTW, here's the output that I do get.

Makes sense. The patch on top of the latest -mm is below if you want to push
it. It has not been boot tested as building with the latest -mm is broken
at the moment for older powerpcs because of the git-powerpc.patch patch .
That patch assumes that mm_context_t is a struct with a vdso_base which is
not always the case (it's an unsigned long in include/asm-ppc/mmu.h).

It says "Welcome to Linux gentoo-2.6.15-r5" and then I see four
lines, MSR, HID0 and hex printout of each.

That's it.

I get the usual messages spooled to the serial console. My args are;

I've tried what you've mentioned below, i.e removing the /sbin/init and
just having the /bin/sh in the init/main.c file and I don't get a
standalone shell. I am having a Linux 2.4 Kernel (Montavista 3.1)
running on a PPC405 in a Xilinx Virtex4 FX100 FPGA.

You mentioned it could be a hardware problem. Are there any errata which
could explain the h/w bug?=20

    For debugging or single user purposes you do not need to run init or
have an inittab.
    There have been several sugestions that there may be a hardware
problem - there are a number that are possible.

    I was stalled here for some time because my UartDriver was
accidentally using the physical IO address instead of the virtual one
    and I had created a temporary phys=3Dvirtual entry in the tbl that =
was
conveniently getting blow away just here.

    You can try to isolate your problem by changing your boot ramdisk
(inramfs or initrd)

    Eliminate or rename /init /sbin/init /linuxrc and any of the other
permutations that linux tries to execute in init/main.c they are all
listed very near where you stopped.
    make sure you have /bin/sh

    reboot on that ramdisk  if you have an "init" related problem then
you should get a standalone shell.
    If you have a hardware problem you will likely still stop at the
same place.

For arch/ppc?  Not that I'm aware of.  But that wasn't particularly my
point.  The email says "This patch updates the ppc and powerpc
architectures..." when it doesn't.

I think most agree that arch/ppc needs to die via a complete migration
to arch/powerpc.  But patches shouldn't claim to do something they
don't :).

Why? Just because older hardware wasn't capable of enforcing the

It does?  I only see arch/powerpc in the patch.  Is arch/ppc hiding

If the user gave no boot arguments on the boot command, -1 and 1
are the only two valid return values even, and -1 is only valid
if no "boot" or "load" command was used to load the kernel.
Makes me wonder what those XServe's do ;-)

(0 isn't valid as the property is encoded with encode-string, which
puts a trailing 0 byte on the empty string.  Doesn't hurt to check
for it anyway of course ;-) ).

* 32 bit userland on G5
From: Johannes Berg @ 2006-06-13 10:25 UTC (permalink / raw)
  To: linuxppc-dev list

Hi,

Since apparently the G5 honours no-execute permissions, shouldn't the 64
bit kernel set the READ_IMPLIES_EXEC personality flag for 32-bit
userland?

The memory being execute-protected is causing a mono bug
(http://bugzilla.ximian.com/show_bug.cgi?id=77028) but I'm not sure
where the correct fix would be, currently the kernel doesn't seem to be
behaving exactly the same on G4 and G5.

Sure, I'll continue maintaining snd-aoa in that repository.

I see your patch is in, I'll make a patch that fixes it then instead of
replacing it, I guess.

 Hi, 
  	This series of patch adds mpc7448hpc2 (taiga) board 
 support in arch/powerpc.	
 	Tsi108 chip of Tundra Semiconductor is also supported.
	The code has been revised according to the feedback.
