I already explained it. What *exactly* does not work if you change the
Makefiles as I explained?

* [PATCH] fix udevtrigger first/default/last ordering
From: Thomas de Grenier de Latour @ 2006-04-08 15:51 UTC (permalink / raw)
To: linux-hotplug
[-- Attachment #1: Type: text/plain, Size: 339 bytes --]
Hi,
There is some logic in udevtrigger (udev-0.89 or current git) to make
some events being triggered first or last. But it doesn't work because,
in device_list_insert(), some "sysfs_path"-prefixed devices paths are
compared to some unprefixed paths (the ones from first_list/last_list).
The attached patch fixes that.
Thanks,
--
TGL.

Well, I figured out why I was getting the EXT2-fs warning: I had
forgotten to build ext3 support into the kernel.. I don't think I
damaged my disk though, cause it mounts the system as read-only at
first, and by the time it mounts it read-write, the ext3 module is
loaded.
I've also finally managed to get /dev/md0 mounted while booted from an
initramfs image. I used the stock debian mkinitramfs script and for
some reason it decided to start working. I really can't figure out
why I had so much trouble with it in the beginning, but it seemed to
start working after I had manually entered the command "mdadm
-Acpartitions --super-minor=0 --auto=part /dev/mda" after being
dropped into busybox - perhaps this changed the superblocks on
/dev/hdc1 or something that I'm not aware of..

I ended up changing the number in /proc/sys/dev/raid/speed_limit_min to
150000. I also disconnected the CDROM from the secondary IDE channel,
replaced the 40 conductor cable with an 80 conductor cable and enabled
UDMA mode 5 on both my hard drives. I now get the following when
syncing:
[12:44AM][mike@asterisk]% cat /proc/mdstat
Personalities : [raid1]
md0 : active raid1 hda1[2] hdc1[1]
158577472 blocks [2/1] [_U]
[>....................] recovery = 0.2% (469056/158577472)
finish=78.6min speed=33504K/sec
So it seems I managed to get the sync time down from 25 hours to 78,
which of course is much more reasonable ;)
I have one last question though.. When I update /boot/grub/menu.lst
while booted from /dev/md0 with both disks available, does this file
get written to the MBR on both disks, or do I have to do this
manually?
Just wanted to say thanks to everybody that helped and offered advice,
I'm really glad that I finally managed to resolve this problem - even
with a backup, I still get very worried about messing with my data.

I'm using a bootloader I wrote that takes advantage of the download
over USB facility of the on-die ROM. I'm waiting for some confirmation
from TI before making the boot code available. We have an agreement
allowing us to use their documentation under NDA to write open source
drivers but there are exclusions regarding some security features
of OMAP, etc, that I need to be sure we are in compliance with.
It shouldn't be too hard to modify u-boot to work with fsample,
but it is not something I've done.

Oops -- I missed that one. Attached is an updated patch that includes

As Hiroyuki-san points out we can need up to 30 bits to encode large 64
bit machines right now. Reducing the space available for FIELDS but
reducing FLAGS_RESERVED for 64 bit machines will negativly impact them
when SPARSEMEM is enabled. I think it makes much more sense here to use
the bits which have been released by the movement of the FIELDS upwards
in the 64 bit case.
32 bit -------------------------------| FIELDS | FLAGS |
64 bit | FIELDS | ?????? FLAGS |
63 32 0
Logically we should in the general case have FLAGS_RESERVED in 64 bit be
the value for 32 bit + 32; currently 9 + 32. If we desire to have 64
bit only flags then it seems keeping FLAGS_RESERVED at 32 for 64 bit
would leave '32 bit FIELDS' segment free for those flags.
In short with the current values of FLAGS_RESERVED I would think
starting at 31 working downwards towards the 'common'/32 bit flags would
be the most logical.
Cheers.

CONFIG_SUPERH) to the alsa-driver build. I am sure somebody knows the
steps needed to make this happen

Just for the record - no, even rebuilding same kernel with same GCC
(3.4.4) under FC5, disk performance is much slower than FC3 -
according to hdparm _and_ dd tests.

Not complete yet !. Check drivers/i2c/chips in our tree and you will
find x1205.c driver, which is not present in the linus tree, as it was
moved to new rtc subsystem folder with new name rtc-x1205.c. So I
believe there will more locations like this...:)

* [PATCH] xdiff/xdiffi.c: fix warnings about possibly uninitialized variables
From: Marco Roeland @ 2006-04-08 15:27 UTC (permalink / raw)
To: git; +Cc: Davide Libenzi
Compiling this module gave the following warnings (some double dutch!):
xdiff/xdiffi.c: In functie 'xdl_recs_cmp':
xdiff/xdiffi.c:298: let op: 'spl.i1' may be used uninitialized in this function
xdiff/xdiffi.c:298: let op: 'spl.i2' may be used uninitialized in this function
xdiff/xdiffi.c:219: let op: 'fbest1' may be used uninitialized in this function
xdiff/xdiffi.c:219: let op: 'bbest1' may be used uninitialized in this function
A superficial tracking of their usage, without deeper knowledge about the
algorithm, indeed confirms that there are code paths on which these
variables will be used uninitialized. In practice these code paths might never
be reached, but then these fixes will not change the algorithm. If these
code paths are ever reached we now at least have a predictable outcome. And
should the very small performance impact of these initializations be
noticeable, then they should at least be replaced by comments why certain
code paths will never be reached.
Some extra initializations in this patch now fix the warnings.

OK, Take 3. 48Hz are only available if explicitly listed in board
definition.
Make HZ configurable. DECSTATION can select 128/256/1024 HZ, JAZZ can
only select 100 HZ, others can select 100/128/250/256/1000/1024 HZ if
not explicitly specified). Also remove all mach-xxx/param.h files and
update all defconfigs according to current HZ value.

Well, it looks like we didn't free enough RAM for suspend in this case.
Unfortunately we were below the min watermark for ZONE_NORMAL and
we tried to allocate with GFP_ATOMIC (Nick, shouldn't we fall back to
ZONE_DMA in this case?).
I think we can safely ignore the watermarks in swsusp, so probably
we can set PF_MEMALLOC for the current task temporarily and reset
it when we have allocated memory. Pavel, what do you think?

Note that you can support sample accurate start for both streams (linked
streams). See pci/ice1712/ice1712.c - snd_ice1712_pro_trigger() for
example.

* [Xenomai-core] [BUG?] stalled xeno domain
From: Jan Kiszka @ 2006-04-08 15:12 UTC (permalink / raw)

[-- Attachment #1.1: Type: text/plain, Size: 8289 bytes --]
Hi Philippe,
debugging is nice, tracing is still nicer. As you suggested, I extended
the tracer with per-domain stall flags (needs some output clean-up,
preliminary patch attached nevertheless).
And here is the result (full trace attached):

The '*' mark a stalled domain, root domain on the right. It seems to me
that xnpod_suspend_thread() leaves the xeno domain stalled on wake up.
This gets recovered somehow later.
But here we see a different effect which finally causes the tick to get
frozen:

No more recovery from the xeno stall, no more timer ticks.
The special traces were generated via
#define ipipe_mark_domain_stall(ipd,cpuid) \
ipipe_trace_special(0x50, ipd->priority)
#define ipipe_mark_domain_unstall(ipd,cpuid) \
ipipe_trace_special(0x51, ipd->priority)
Any ideas? I do not find anything fishy yet that we may have introduced
to cause this problem.

* NATed packets only enter the default routing table
From: richard lucassen @ 2006-04-08 15:07 UTC (permalink / raw)
To: netfilter

I set up this config:
+------+
-+ ISP1 +--+
+------+ | +-------+
+--+ linux |
+------+ | +-------+
-+ ISP2 +--+
+------+
No problem. Standard setup with two ISP's. Both routed subnets. Default
gateway is ISP1. No magic here.
Now I put a server behind the Linux box. I want the server to be
reachable on an /extra/ IP in the routed subnet of ISP2.
+------+
-+ ISP1 +--+
+------+ | +-------+ +-----------------+
+--+ linux +--+ server 10.0.0.2 |
+------+ | +-------+ +-----------------+
-+ ISP2 +--+
+------+
router ISP2: 1.2.3.1/24
dev ISP2: eth1
Linux box eth1: 1.2.3.2/24
external ip ISP2 for server 10.0.0.2: 1.2.3.3
arp -s 1.2.3.3 aa:bb:cc:dd:ee:ff pub
ip route add 1.2.3.3 via 10.0.0.2
iptables -t nat -A PREROUTING -i eth1 -d 1.2.3.3 -j DNAT --to 10.0.0.2
When pinging 1.2.3.3, the packets get in through eth1 (ok), but the
replies are following the default routing table through eth0 (wrong)
Even a
ip rule add from 1.2.3.3 lookup table_eth1
doesn't change this behaviour. It is working ok when I add the address
1.2.3.3 directly to eth1 (without NAT):
ip a a 1.2.3.3 dev eth1
Why is this?

CPUID never faults. Well, unless the processor doesn't support the
instruction, but you find that out from EFLAGS.

I would definitely prefer to use MSRs for gathering hypervisor
signature and other information, but because of the possible hassle of
catching faults I'd also support a signature return (and maybe
identifying some hypervisor features) via a special CPUID index. The
index could be greater than the normal "max count" and you'd determine
if the index(es) were supported by checking for a well-known signature
in EAX,EBX,ECX,EDX for the first of the hypervisor indexes. Running on
native hardware would not fault and you'd expect it to be vastly
unlikely that the final values of EAX thru EDX would coincidentally
match a 128-bit signature.
(Cue attempts to think up a 16-character signature string. :-)

Replying to myself.
I noticed that the lspci -v output looks like this:
00:0a.1 SMBus: nVidia Corporation MCP51 SMBus (rev a2)
Subsystem: nVidia Corporation: Unknown device cb84
Flags: 66Mhz, fast devsel, IRQ 5
I/O ports at 0600 [sized]
I/O ports at 0700 [sized]
Capabilities: [44] Power Management version 2
The hacked i2c-nforce2 wasn't working because the call to
pci_read_config_word() was returning 0x00 for the iobase .
I made another quick hack to i2c-nforce2 to hardcode iobase=0x600 for
the first smbus interface and iobase=0x700 for the second smbus
interface.
Now the modules load and decode-dimms.pl is working.
I'm not much of a kernel hacker, so tell me if you need any more information.

I gathered data on my side too, the three R52 I had reports for used
"ThinkPad R52" but these had different machine type/model. I guess that
the 1846AQG is somehow different, but probably you don't know why?
So I suppose we could add that "ThinkPad H" identifier string to the
hdaps driver after all, as you proposed in the first place. I'm only
worried that the "H" suffix is really short, and I hope that no other
model not supported by the driver (or needing the invert option) will
ever have the same identifier. Time will tell.
Thanks,

Most of the ifconfig-exported stuff is obsolete, simply because most of
it is quite inappropriate for hardware more modern than ISA.
dev->mem_start has been a hacky way to pass options for over 10 years
now, since only few, rare drivers use it to specify the ISA memory
region for probing.

netdev->irq is obsolete as well. Some newer drivers don't even bother
to set it. With PCI, it became write-only, because modern drivers
autoprobe their irq, ignoring whatever the user requests. With PCI
MSI[-X] and even more modern hardware, dev->irq is just a cookie, not
something to program PCI_INTERRUPT_LINE with. So setting netdev->irq is
even less useful.
Programs which need to discover hardware information when given a
network interface name should do ETHTOOL_GDRVINFO, get the bus info, and
then obtain the information needed in a bus-specific way.

That's one way.
Jumps, conditional or unconditional come in two sizes, "short" and
"near". Weird that the longer jump is called "near", but that's the way
it is. There's also a "far" jump which loads cs as well as eip. This
isn't very useful in Linux, at least not in "user" code...
Nasm defaults to "near" for unconditional jumps:
jmp my_label
Will jump +/- 2G-1 bytes (assuming 32-bit code). This will always
"reach", but may produce longer code than necessary, since the parameter
takes up four bytes. If the target is within -128/+127 bytes, we can do:
jmp short my_label
...and the parameter is stored as just one byte. (note that these
instructions use "relative addressing" - we write "my_label", but what's
emitted for code is the "distance", forward or back, to "my_label") If
you do this, and "my_label" is more than 127 bytes away - or becomes so
as code is modified - you'll see that "out of range" message.
[H.P. Recktenwald (Hi, hp!) showed me a neat trick - pre "-O" switch -
to deal with this - "%define jm jmp short", then use "jm" for all your
unconditional jumps. If Nasm complains "out of range", just add "p"!]
Conditional jumps default to "short". Nasm doesn't want to default to
"near", since it's not available on 8086 (and we write a lot of code for
8086 :)... If the target is farther than 127 bytes away, we can:
jz near my_label
The "-O" switch alters these defaults. "-O1" is "special" - it will size
a "backward" jump "as required", but forward jumps are "near", to
guarantee they'll reach. Parameters greater than 1 enable that many
(maximum) passes, so that jumps can be "sized" optimally. It *used* to
be that "-O2" and "-O3" were "special cased" to 10 and 15 passes, but
this has been changed - "-O2" and "-O3" are *not* enough, and are in
fact "buggy" currently. There is no advantage to using a small number -
Nasm quits when it's done. I usually use "-O999" if I use it at all.
The other effect of the "-O" switch - any parameter (>0) - is to enable
the shorter "signed byte" form of instructions that have a short form,
but that's a different issue...

As Leslie says, I think we're going to need to see the code for that
one. Doesn't sound right. (possibly from using "-O2"??? - does ld
complain about "can't find entrypoint"???)

* 40% IDE performance regression going from FC3 to FC5 with same kernel
From: Alessandro Suardi @ 2006-04-08 14:47 UTC (permalink / raw)
To: Linux Kernel
[-- Attachment #1: Type: text/plain, Size: 2866 bytes --]
I'll be filing a FC5 performance bug for this but would like an opinion
from the IDE kernel people just in case this has already been seen...
I just upgraded my home K7-800, 512MB RAM box from FC3 to FC5
and noticed a disk performance slowdown while copying files around.
System has two 160GB disks, a Samsung SP1604N 2MB cache and
a Maxtor 6Y160P0 8MB cache; both disks appear to be almost 2x
slower both on hdparm -t tests (17-19MB/s against 33/35 MB/s) and
on dd tests, like this:
FC3
[root@donkey tmp]# time dd if=/dev/hda of=/dev/null skip=200 bs=1024k count=200
200+0 records in
200+0 records out
real 0m4.623s
user 0m0.004s
sys 0m1.308s
FC5
[root@donkey tmp]# time dd if=/dev/hda of=/dev/null skip=200 bs=1024k count=200
200+0 records in
200+0 records out
209715200 bytes (210 MB) copied, 9.67808 seconds, 21.7 MB/s
real 0m9.683s
user 0m0.008s
sys 0m1.400s
The initial tests were my last FC3 self-compiled kernel (2.6.16-rc5-git8)
vs FC5's 2.6.16-1.2080_FC5 kernel; so just to be sure, I copied over
from my FC3 partition the 2.6.16-rc5-git8 kernel and its config file,
and rebuilt it under FC5, with just a few differences for the new USB
2.0 disk I added to a PCI controller I just put in, namely
[root@donkey linux-2.6.16-rc5-git8]# diff .config
/fc3/usr/src/linux-2.6.16-rc5-git8/.config
4c4
< # Fri Apr 7 03:58:23 2006

The result is unexpected - performance delta is still there. Concatenating
output from hdparm -i /dev/hda and hdparm /dev/hda for the same kernel
under FC3 and FC5, the only difference is
[root@donkey ~]# diff /tmp/hdparm.out.2616rc2git8-fc5
/tmp/hdparm.out.2616rc2git8
14c14

---
> geometry = 19457/255/63, sectors = 160041885696, start = 0
I'll try now and rebuild a 2.6.16-rc5-git8 kernel under FC5 with the
FC3 GCC and see whether that is responsible for the performance
drop... of course if anyone has any idea about what's going on, I
will be happy to try out stuff. Attaching hdparm output from the FC5
2.6.16-rc5-git8 just to show that there is DMA etc. all configured fine.
Thanks in advance, ciao,

don't do default n, just remove the line instead ;)
