* [PATCH] x_tables: fix alignment on [at least] ppc32 (was Re: 2.6.16-rc1: iptables broken on ppc32?)

Hi,
the patch below fixes the problem on ppc32. Dave: Please apply.
[NETFILTER] x_tables: Fix XT_ALIGN() macro on [at least] ppc32
To keep backwards compatibility with old iptables userspace programs,
the new XT_ALIGN macro always has to return the same value as IPT_ALIGN,
IP6T_ALIGN or ARPT_ALIGN in previous kernels.
However, in those kernels the macro was defined in dependency to the
respective layer3 specifi data structures, which we can no longer do with
x_tables.
The fix is an ugly kludge, but it has been tested to solve the problem. Yet
another reason to move away from the current {ip,ip6,arp,eb}tables like
data structures.

Harald, I'm going to modify this to just use u_int64_t as that
should be totally sufficient.
It is the largest type, and will produce the desired results without
the silly structure.
Some malloc() implementations use "long double" to figure out the
largest type size and alignment requirements any C type might have
on the machine. But there is no reason to use that here.

Hi
We are able to port the linux 2.6 in our target board.As the
MPC860T has 4 SCC ports and two SMC ports.I want to up all the SMC and SCC
ports.When I am selecting all the options in the kernel configuration
It is getting hanged.
I did n't see any mknod in the code
how can I know ttyCPM2 is for SMC2.At the time of ramdisk building I have created the the softlink to ttyCPM2 ->console
ttyCPM1 is for SMC1 like that
and they mentioned only major number is 204 minor number is 46
As we want to use 6 ports.We want 6 minor numbers
when I am selectind SMC and all SCC' s the o.s is up in the target board( as the program did not have any portpin configuartions for the SCC's)
when I am selecting SMC1 and SMC2 it is getting hanged

Hello.
Please, help me to investigate why the delays present in the
"mpc5xxx_read_config_dword" and "mpc5xxx_write_config_dword" functions
in the "arch/ppc/kernel/mpc52xx_pci.c" file.
I.e.
==========================
*(volatile u32 *)MPC5xxx_PCI_CAR = 0;
> udelay(10);
return 0;
==========================
I was neither able to find any reference at the MPC5200 documentation
supplied by FreeScale nor reproduce any error with these lines got
removed.
Thank you.

ACK. Both Harald's patch and DaveM's simplification of it
(simply s/void */u_int64_t/g in XT_ALIGN()) fix the iptables
problems on my ppc32 box.

* [PATCH] sound/ppc/pmac.c typo.
From: Stelian Pop @ 2006-01-20 10:35 UTC (permalink / raw)
To: linuxppc-dev
In 2.6.16-rc1 there is a small typo introduced by the 'Remove device_node addrs/n_addr' changes
which prevents my Powerbook G4 sound from working:
Advanced Linux Sound Architecture Driver Version 1.0.11rc2 (Wed Jan 04 08:57:20 2006 UTC).
snd: can't request rsrc 0 (Sound Control: 0x80000000:80004fff)
ALSA device list:
No soundcards found.
The patch below fixes it. Of course, the patch fixing the i2c issues
('i2c_smbus_write_i2c_block_data' patch) needs to be applied to in order for
the sound to completly work.

I guess you mean something like this code snipped from the efficeon-agp.c
source code (with pci_assign_resource()):
---
/*
* The following fixes the case where the BIOS has "forgotten" to
* provide an address range for the GART.
* 20030610 - hamish@zot.org
*/
r = &pdev->resource[0];
if (!r->start && r->end) {
if(pci_assign_resource(pdev, 0)) {
printk(KERN_ERR PFX "could not assign resource 0\n");
return -ENODEV;
}
}
/*
* If the device has not been properly setup, the following will catch
* the problem and should stop the system from crashing.
* 20030610 - hamish@zot.org
*/
if (pci_enable_device(pdev)) {
printk(KERN_ERR PFX "Unable to Enable PCI device\n");
return -ENODEV;
}
/* Fill in the mode register */
if (cap_ptr) {
pci_read_config_dword(pdev,
bridge->capndx+PCI_AGP_STATUS, &bridge->mode);
}
pci_set_drvdata(pdev, bridge);
----
BTW: I took a look at the PCI resources list of the AmigaOne and found out
that the resources of the AGP graphic card are allocated to bus 0 (PCI
only). IMHO their allocation should be assigned to bus 1 (AGP) (at least
this is the case on x86!?), so I think this should be fixed. Is my
assumption correct?
Thanks!

I know that the BDI2000 works fine, and some people have been
successfully using the vision* tools, too (often after some
struggeling).
My personal tool of choice is the BDi2000.
Use the tool you know best...
And yes, single stepping is possible if your tool allows it.
Note that this question is off topic on this list; you should post
such questions on the U-Boot mailing list. But please ntoe that...

Thanks, I applied it to ALSA tree now.

Now, I’m in trouble with porting Linux to AMCC PPC405EP.
I think u-boot was ported successfully, So, I compile linux kernel 2.6.14
with crosstool-0.38

Thanks.
BTW, is it a hardware or a configuration issue the fact that I'm unable
to mix several alsa streams ?
For example, if I issue two instances of 'aplay foo.wav', the first one
plays the sound while the second one remains stuck in:
stat64("/usr/share/alsa/alsa.conf", {st_mode=S_IFREG|0644, st_size=7467, ...}) = 0
open("/dev/snd/controlC0", O_RDONLY) = 3
close(3) = 0
open("/dev/snd/controlC0", O_RDWR) = 3
ioctl(3, USBDEVFS_CONTROL, 0x7fee2bf8) = 0
ioctl(3, UI_DEV_CREATE, 0x7fee2ca0) = 0
close(3) = 0
open("/dev/snd/controlC0", O_RDONLY) = 3
close(3) = 0
open("/dev/snd/controlC0", O_RDWR) = 3
ioctl(3, USBDEVFS_CONTROL, 0x7fee2fa8) = 0
ioctl(3, 0x80045532, 0x7fee2fd8) = 0
open("/dev/snd/pcmC0D0p", O_RDWR
until the first one ends playing. Only then the second one continues the
execution.
Just in case this is useful:
# cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.11rc2 (Wed Jan 04 08:57:20 2006 UTC).
# cat /proc/asound/cards

Did you install alsa-lib 1.0.11rc2, too? It should work with dmix as
default.

This is an ubuntu breezy ppc distribution, and it seems that the package
is called libasound2, and it is based on alsa-lib 1.0.9-2.
Stracing the aplay process shows that dmix.conf is being read:
defiant:~ 20 > strace -eopen aplay wav/slow_20spindle_20motor.wav
open("/etc/ld.so.cache", O_RDONLY) = 3

open("/usr/share/alsa/alsa.conf", O_RDONLY) = 3
open("/usr/share/alsa/cards/aliases.conf", O_RDONLY) = 3
open("/usr/share/alsa/pcm/default.conf", O_RDONLY) = 4
open("/usr/share/alsa/pcm/dmix.conf", O_RDONLY) = 4
open("/usr/share/alsa/pcm/dsnoop.conf", O_RDONLY) = 4
open("/dev/snd/controlC0", O_RDONLY) = 3

open("/dev/snd/controlC1", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/dev/aloadC1", O_RDONLY) = -1 ENOENT (No such file or directory)
[...]
I suppose I could test with 1.0.11rc2 if it does make sense to.

1.0.9 doesn't use dmix as default.

Ok, using 1.0.11rc2 works with dmix indeed.
Aplay works correctly. So does xine.
However mplayer seems to have problems with this version of the library:
[...]

alsa-init: 1 soundcard found, using: default

alsa-space: xrun of at least 0.005 msecs. resetting stream
alsa-space: xrun of at least 0.005 msecs. resetting stream
But it could be mplayer's fault at this point.

Sorry dave, as I just learned, it isn't. As reported by Jiri Slaby
<xslaby@fi.muni.cz>, Linus' tree now breaks on i386 :(
Interestingly, on i386:
__alignof__(struct _xt_align) 4
__alignof__(u_int64_t) 8
__alignof__(void *) 4
whereas on ppc:
__alignof__(struct _xt_align) 8
__alignof__(u_int64_t) 8
__alignof__(void *) 4
So your assumption that __alignof__(u_int64_t) == __alignof__(struct xt_align)
doesn't hold true for all archs.
I would therefore recommend applying my unmodified patch, and hope that
it then works on all archs simultaneously.

Our main problem is that we have to stay compatible with old userspace
programs that had a different definition for what has now become
XT_ALIGN(). So independent what might be the best solution from an
alignment point of view, we must match what old userspace thinks.
Yes, this all sucks. And yes, we will see a new interface this year.
Promised.
Cheers,
Harald.
