Sure sounds like a great idea. I just signed up for a large partition (>
1700 GSIs) to try this over the weekend.
The problem with oapic_renumber_gsi() is that it didn't actually migrate
to x86_64 because it doesn't have sub-archs so far. But using actual
number of interrupts vs. range is definitely promising idea. I was also
thinking that all the complexity is actually located on the first
IO-APIC, this may have some potential for compression only coming into
play on non-zero IO-APICs. But using the total number of IRQs used is
definitely the most logical thing to try...I will test this shortly -

Did you shorten the queue on the network interface? If there are already
some packets which the kernel dequeued to the interface, your ICMP
packet will have to wait until they have been sent. The only longer
queue should be the one in the kernel, because only there the high
priority traffic gets queued before the already waiting packets, all
hardware queues are FIFOs.

You should not use sfq for high priority traffic, it is only useful for
bulk traffic - there should never be as much high priority traffic as to
make sfq needed to stop one flow from starving another, and if you use
it, your latency will rise.

* mptable program
From: Dan Carpenter @ 2006-05-06 6:49 UTC (permalink / raw)
To: linux-kernel, fsmp
Steve Pass wrote an mptable program for FreeBSD back in the day. I
patched it up to compile on 64 bit linux systems.
It's on:
http://smatch.sourceforge.net/upload/mptable.c
Steve has some sample output uploaded here.
http://people.freebsd.org/~fsmp/SMP/mptable/mptable.html
These days most things use ACPI, but it's still pretty useful if you
have to support older software.

Then _get rid of your init.d_.
SysV init sequence is insane.
I use daemontools-based setup and it starts up to login prompt
in 5-10 secs (counting from the root fs mount).
In my setup, after a few simple startup scripts a svscan process
is called, which starts all services in parallel.
Gettys are services, and start right away.

* [PATCH] XATTR support on JFFS2 (version. 5)
From: KaiGai Kohei @ 2006-05-06 6:51 UTC (permalink / raw)
To: dwmw2, joern, linux-mtd; +Cc: jmorris, sds, lorenzo, russell
[-- Attachment #1: Type: text/plain, Size: 1367 bytes --]
Hello,
This attached patches provide xattr support including POSIX-ACL and
SELinux support on JFFS2 (version.5).
We can apply those patches to the latest git-tree.
- xattr_on_jffs2.kernel.version-5.patch can be applied to mtd-2.6.git.
- xattr_on_jffs2.utils.version-5.patch can be applied to mtd-utils.git.
There are some significant differences from previous version posted
at last December.
The biggest change is addition of EBS(Erase Block Summary) support.
Currently, both kernel and usermode utility (sumtool) can recognize
xattr nodes which have JFFS2_NODETYPE_XATTR/_XREF nodetype.
In addition, some bugs are fixed.
- A potential race condition was fixed.
- Unexpected fail when updating a xattr by same name/value pair was fixed.
- A bug when removing xattr name/value pair was fixed.
The fundamental structures (such as using two new nodetypes and exclusion
mechanism by rwsem) are unchanged. But most of implementation were reviewed
and updated if necessary.
Espacially, we had to change several internal implementations related to
load_xattr_datum() to avoid a potential race condition.
[1/2] xattr_on_jffs2.kernel.version-5.patch
[2/2] xattr_on_jffs2.utils.version-5.patch
Signed-off-by: KaiGai Kohei <kaigai@ak.jp.nec.com>
We can get those patches from http://www.kaigai.gr.jp/
Any comments please. Thanks,

+ * xattr_datum_hashkey(xprefix, xname, xvalue, xsize)
+ * is used to calcurate xdatum hashkey. The reminder of hashkey into XATTRINDEX_HASHSIZE is
+ * the index of the xattr name/value pair cache (c->xattrindex).
+ * unload_xattr_datum(c, xd)
+ * is used to release xattr name/value pair and detach from c->xattrindex.
+ * reclaim_xattr_datum(c)
+ * is used to reclaim xattr name/value pairs on the xattr name/value pair cache when
+ * memory usage by cache is over c->xdatum_mem_threshold. Currentry, this threshold
+ * is hard coded as 32KiB.
+ * delete_xattr_datum_node(c, xd)
+ * is used to delete a jffs2 node is dominated by xdatum. When EBS(Erase Block Summary) is
+ * enabled, it overwrites the obsolete node by myself.
+ * delete_xattr_datum(c, xd)
+ * is used to delete jffs2_xattr_datum object. It must be called with 0-value of reference
+ * counter. (It means how many jffs2_xattr_ref object refers this xdatum.)
+ * do_verify_xattr_datum(c, xd)
+ * is used to load the xdatum informations without name/value pair from the medium.
+ * It's necessary once, because those informations are not collected during mounting
+ * process when EBS is enabled.
+ * 0 will be returned, if success. An negative return value means recoverable error, and
+ * positive return value means unrecoverable error. Thus, caller must remove this xdatum
+ * and xref when it returned positive value.
+ * do_load_xattr_datum(c, xd)
+ * is used to load name/value pair from the medium.
+ * The meanings of return value is same as do_verify_xattr_datum().
+ * load_xattr_datum(c, xd)
+ * is used to be as a wrapper of do_verify_xattr_datum() and do_load_xattr_datum().
+ * If xd need to call do_verify_xattr_datum() at first, it's called before calling
+ * do_load_xattr_datum(). The meanings of return value is same as do_verify_xattr_datum().
+ * save_xattr_datum(c, xd, phys_ofs)
+ * is used to write xdatum to medium. xd->version will be incremented.
+ * create_xattr_datum(c, xprefix, xname, xvalue, xsize, phys_ofs)

+1 -- explicit file ids are evil. Arch/TLA demonstrated that amply...
they are a serious annoyance to the end user, they have a lot of
not-elegantly solvable cases (same file created with the same contents
in several repos -- say via an emailed patch) that git gets right
_today_.
They _are_ useful in a very small set of cases -- namely in the case
of a naive mv, which git handles correctly today. Subtler things git
sometimes does right, sometimes fails, but it can be made to be much
smarter by interpreting content changes better, for instance all this
talk about getting pickaxe to guess where the patch should be applied
for a file that got split into 3.
But those subtler cases are totally impossible with explicit id
tracking. I used Arch for a long time with very large trees, and
renames coming left, right and centre. Explicit ids didn't help much,
and the number of manual fixups we had to do was awful.
I am using GIT with the very same project, and just now, typing this,
I realised that there are still many renames happening in the project.
I had forgotten about it -- well, not really: I do use git-merge
instead of cg-merge when I suspect there may be interesting cases ;-)
Of course, YMMV, and I have to confess I was a sceptic for a while...
but now as an end-user dealing with messy projects, I say LIRAR: Linus
Is Right About Renames.

I agree here with Pasky that after a while the automated
renames/copy/splitup detection will miss the operation in cases where
it would be interesting to note it to the user. IIRC git-rerere is the
tool that knows about this (still voodoo to me how) and could be used
to help here. At what (runtime) cost, I don't know, but that kind of
walking history to tell me more interesting things about the diff is
something that is usually worthwhile.
Usual disclaimers apply.

One benefit I see is that one avoids extra filters, this can be useful

Commit maybe, but is this based on a hard fact?
Earlier Linus said something about "git log" working on
commit-only copy, but obviously you would want at least trees
for the path limiting part to work, so having commits and trees
would be handy, but my impression was that at least for deep
project like the kernel trees tend to be nonnegligible (a commit
consists of 18K paths and 1200 trees or something like that).

No. The caller must not call device_initialise(). They either use
platform_device_alloc() and platform_device_add(), or
platform_device_register(). Same rules apply to these as they
do for device_add() vs device_register().

Just remove the call to device_initialise() in platform_device_add() -
that's something I missed when I renamed platform_device_register to
platform_device_add().

FYI rerere is a totally unrelated voodoo.
It remembers the conflict marker pattern <<< === >>> immediately
after it runs "merge" (ah, that reminds me -- I should replace
them with diff3), and then remembers the result of the manual
resolution just before the user makes a commit. Then, when next

pattern it has seen before, it runs a three-way merge between
the previous resolution result and the current conflicted state,
using the previous conflicted state as the common origin.

OK, now it passes the testsuite I wrote, so I'll push this out

* Reiser4 2.6.16.2 / 2.6.17-rc3-mm1 WARNING: out of memory?
From: Joseph Landers @ 2006-05-06 7:57 UTC (permalink / raw)
To: reiserfs-list
Hi there,
I have tried to compile the 2.6.17-rc3-mm1 patchset with kernel 2.6.16.14 by
patching in the order specified in patch-series and adding the missing
writeback 1of2 patch that was missing from the ftp. It compiles and I can
mount the partition but I get this error if I boot from the partition

I also get the same error if I grab the reiser4-2.6.16.2 and patch it
against 2.6.16.14
I then tried just compiling the 2.6.17-rc3-mm1 with reiser4 enabled and
mounting the reiser4 and installing the kernel.deb to it
I got this error when I tried to dpkg -i kernel.deb

get_nonexclusive_access(uf_info, 1) instead of 0 but this has no effect
I really want to get my reiser4 partition working properly
If you need any more info please ask

I can use IODATA GV-BCTV4/PCI by kernel 2.6.14,
but can't use same card by kernel 2.6.16 or later version.
I would like to use IODATA GV-BCTV4/PCI by kernel 2.6.16 or later version.

* [Xenomai-core] [RFC] Micro-optimisations for the libs
From: Jan Kiszka @ 2006-05-06 8:09 UTC (permalink / raw)
To: xenomai-core; +Cc: Daniel.Rossier
[-- Attachment #1: Type: text/plain, Size: 2789 bytes --]
Hi,
[Daniel, I put you in the CC as you showed some interest in this topic.]
as I indicated a some weeks ago, I had a closer look at the code the
user space libs currently produce (on x86). The following considerations
are certainly not worth noticeable microseconds on GHz boxes, but they
may buy us (yet another) few micros on low-end.
First of all, there is some redundant code in the syscall path of each
skin service. This is due to the fact that the function code is
calculated based on the the skin mux id each time a service is invoked.
The mux id has to be shifted and masked in order to combine it with the
constant function code part - this could also easily happen
ahead-of-time, saving code and cycles for each service entry point.
Here is a commented disassembly of some simple native skin service which
only takes one argument.
Function prologue:
460: 55 push %ebp
461: 89 e5 mov %esp,%ebp
463: 57 push %edi
464: 83 ec 10 sub $0x10,%esp
Loading the skin mux-id:
467: a1 00 00 00 00 mov 0x0,%eax
Loading the argument (here: some pointer)
46c: 8b 7d 08 mov 0x8(%ebp),%edi
Calculating the function code:
46f: c1 e0 10 shl $0x10,%eax
472: 25 00 00 ff 00 and $0xff0000,%eax
477: 0d 2b 02 00 08 or $0x800022b,%eax
Saving the code:
47c: 89 45 f8 mov %eax,0xfffffff8(%ebp)
47f: 53 push %ebx
Loading the arguments (here only one):
480: 89 fb mov %edi,%ebx
Restoring the code again, issuing the syscall:
482: 8b 45 f8 mov 0xfffffff8(%ebp),%eax
485: cd 80 int $0x80
487: 5b pop %ebx
Function epilogue:
488: 83 c4 10 add $0x10,%esp
48b: 5f pop %edi
48c: 5d pop %ebp
48d: c3 ret
Looking at this code, I also started thinking about inlining short and
probably heavily-used functions into the user code. This would save the
function prologue/epilogue both in the lib and the user code itself. For
sure, it only makes sense for time-critical functions (think of
mutex_lock/unlock or rt_timer_read). But inlining could be made optional
for the user by providing both the library variant and the inlined
version. The users could then select the preferred one by #defining some
control switch before including the skin headers.
Any thoughts on this? And, almost more important, anyone around willing
to work on these optimisations and evaluate the results? I can't ATM.

Hi everybody, I have one problema with dell poweredge 850 servers.
When I compile linux kernel 2.6.16 with netfilter its works, but when
i apply the patch of h323 protocol i have kernel panic. Kernel not
sync. This servers have a NIC with tg3 module.
if someone can help me, please send me one link or a way that i can
solve this problem,

But after I load the u-boot and run, it seems not work, only stop at the
beginning of the codes and there is not any information at the UART.
