2.4.3 SMP: nfs stale handle, fb dualhead hardlock, G400/450 misnaming
1. stale NFS file handle 2.4.2-ac28 serving nfs3 from reiserfs 2.4.3 being nfs3 client, nfs damn slow on 100Mbps p2p link. mounted nfs with rsize=8192,wsize=8192 nfs fast. soon got : bash-2.04$ls ls .: stale NFS file handle just about home directory it says so. 2. Hard lockup: G450, I set con2fb, switch consoles some times and there it comes. swithc between X and single console is OK. 3. seems that I have G450 and linux shows it as G400. bash-2.04$ /sbin/lspci: 01:00.0 VGA compatible controller: Matrox Graphics, Inc.

G400 drivers also work, but matroxset aint switching second head to monitor output, neither does anything else.

USB mouse jumping

Re: [PATCH] removal of "static foo = 0"
Nice to see again a two cutting-edge-killing opinions.
Every time I really wonder, how such brilliant hackers can be that stupid
that they can not have cake and eat it the same time, and have to scratch
each-others eyes every time.
Use macros.
Kernel has become so big that it really needs universal debugging macros
instead of comments. Comments are waste of brain&fingerpower, if the same
can be explained by long variable names and debug macros.
static Subsystem_module_LocalVariableForThisPurpose;
int Subsytem_module_function_this_and_that(){
DEBUG_ASSERT( Subsystem_module_LocalVariableForThisPurpose == 0 );
DEBUG_ASSERT(MOST_OF_TIME,FS_AREA,MYFS_MODULE, somethingaboutIndodes->node !=
NULL )
}
Those macros would be acceptable if they are unified and taken to
kernel configuration level, so it would be easy to switch them in/out
not only as boolean option but systematically for different levels,
subsystems and modules.

And is because there is quickly handwirtten something that should have been generic for kernel for some long time, not for every driver-writer to reinvent a wheel. Note that there is something that virtually elliminates need for exact user<->kernel level interfaces and userlevel kerneldata manipulation programs and lots of other maintenance pains. And it does it in quite short sentences. Plus, half of that file is direct repeating of some non-exported kernel functions. But, if you think you can do better, then look into aironet4500_rid.c and handcode it (like real K&R people do), instead of using aironet4500_proc.c to operate on it. Also, pcmcia/aironet4500_cs.c has lots of ugly parts. Those which are related to stupid masohistic code repetitions due to pcmcia package interface being "cutting edge optimal stupid" The same true is that 2.4 kernel is, in commercial production sense, late for 6 months. And reason being that the codebase and testing becomes unmanageable. And it becomes unmanageable, because some people only read K&R and try to optimize last bit out of it with using and old book.

Yess Lets say LDBG_* namespace, macros being in general form: LDBG_OPERATION(OPTIMIZATION_LEVEL,SUBSYSTEM,MODULE,ACTION, operation params..)

LDBG_DECLARE_DEBUG_VAR(OPTIMIZATION_LEVEL, SUBSYSTEM, MODULE) woudl declare a global unsigned int subsystem_module_debug = 0 and also sysctl interface to change it. the var would have ACTION bitfields, so user can control debug output runtime for the module. elmer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

So they will ship 8. Plus they will ship a script that recompiles kernel without user crawling in documentation. It should be an option in linuxconf: recompile local kernel: debug-nodebug-optimized-localized-nonmodular-server-router-workstation which compiles and installs 2 hardware/situation optimized/configured kernels: debug and production. I am sure company like redhat can ship a little new linuxconf module. Don't worry, people can make good use of multiple options.

But look at positive side: 1. really few people run development kernels despite the "performance" so it probably will be with nondebug kernels. 2. production kernels get more solid 3. because there could be a lot more debug points in development kernels 4. Distributors are interested in shipping debug-kernels. You see the part that lots of asserts and debug prints may go. I see the advantage, that a lot of them can come, at no cost. Besides, if you want to have some assert anyway, then do not write it with system-wide macro but make your own or mark it as "included allways".

Re: Universal debug macros.
well, really, look the other side: We dont make a way to take info away, we just put a lot more into it and give the option to take it away if it is not needed. With this you get your usual amount of debug info plus a way to have lots more. Oh, and one more point: if linux is going to have nonprofessional endusers space comparable to MSWin, then you probably do not want to have every bug report, because these will be stupid anyway, with or without debug info.

Re: If loadable modules are covered by Linux GPL?
Mike Coleman wrote: > Microsoft is about taking control > away from users and giving it to vendors, and the GPL is, to a degree, the > reverse. True, but for very specific stuff there is no good to go to edges with that. Very much better solution would be if company defines a good generic interface for devices of such-and-such type, commits it to GPL and then uses binary modules. If drivers could run outside ring 0, it would be enev nicer. Hiding driver source back is most part useless. I have here hacked "lotsa of code", legally, "for compatiblity purposes", as the law says. Of course, one side of it was that I hurt companies bussiness. Any move has its positive and negative consequences. The other side was, that they remained in profits, as I 1. discovered a lots of bugs in it(hw, firmware), including several DoS. 2. put it to run 50% faster 3. made solution more cost-effective. Most importantly: 4. created trust - GPL plays against vendors and for public, but vendors who go with it, gain trust by public that vendor probably will not play against public in future. Lots of people have used to choose hardware if it has linux drivers. Not because they would need it right away, but because openess generates trust - about that in next driver version some feature will not be turned off for M$ platform, just for to enforce public to buy additional 15$ pseudo-module and have lots of PiA(pain in *ss) with it. Finally, hiding software interfaces because there is money invested in it is usually result of incompetent bussiness people who understand only movement of dollars. For hardware piece there should be most of difference in hardware... And if software does not make much difference then is no point in hiding it as it can be used only with that hardware. They question to ask yourself: is the loss for gain for competitors from your work higher than gain from being open source, first, fast and trusted by public ? elmer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

Yeah, there is the general problem with such a stuff: if something becomes de facto standard it messes up de jure standard. And, if that hurts more people who use de jure than it hurts the people who misconfigure, then it is just plain impossible in practice to use de jure standard and/or change the "de facto" situation. The real solution is to change "the hurting ratio". Changing MTU from 1500 to 1498 on several US and US<-> Europe backbones would create major mess which would be painful enough to change the situation with small MTU for example. elmer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

The Novell stuff. Sorry to say, but who needs it in real world ? 99% of consumers are happy with NT and are happy with samba. See the generated revenue per marketshare as divided between small-average-large bussinesses and you see, that there is very little place for cutting edge software for file sharing. People just solve software problems in hardware. I have constantly problems getting Pentium 100Mhz to work full-loaded and if I get, I replace it with Pentium 266. For last two years there is more hardware and software power that people can make use of. Interfaces and protocols incompatibility and version instability is the only thing that keeps the money coming from generic-purpose software(operating systems), otherwise everybody just would use linux and samba on top of it, however bad and inefective it may sound from non-linux benchmarkers mouth. If fileserver becomes slow, they replace it and take old to home for kids to play. There is more general conclusion from that: 1. times of revolutionary rapid changes in generic purpose(OS) software is over and there will be one or two (binary and open source) generic purpose software distributions in the world as fast as interoperability will be achieved. 2. It also means that besides MS, there will be no one who manages to charge money for generic-prupose software and if full interoprerability is achieved, neither do they. 3. A lots of programmers get fired and go back to roots - farming work for example :) 4. Innovation currently generates new values, but public can not make use of it in reasonable ways and therefore it will not be rewarded. GPL(linux) may also go bancrupt in sense that if MS drops NT server price down to 70$ and copies all new ideas, linux will be for freaks and paranoid and MS can earn revenue from applications. However, there is another possible way: 100% interoperability is achieved and however ineffective the linux solution is, people will use that. But the worst nightmare for linux would be if MS goes open source with its OS. Because then US foreign affairs department will enforce strict copyrigth laws and forging and stealing software will be made impossible and all new ideas would be patented and bought up. You see, if binary software is banned, that makes possible way more deep monopoly schemes. And then it would be either GPL or MS (patent-or-legal-rights-buy-up-office) who owns the software of the world. elmer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

several lockups and performance
Hi, 2.4.0-test8, 2.4.0-test7, 2.4.0-test5 1. bridge. If to set bridge addr on C level after bridge is created, but before any interfaces are ever attached to it, it oopses. The box I am doing it is quite embedded and I am too lazy to set up any serial line debugging or nfs root, so I could say about it at the moment, that it occurs somewhere in bridge code around kmallocing. 2. 3c509 isapnp 3c509 goes up straight, but, with cards configured pnp-mode, with 4 cards, there will be a lockup after the second one. It is probably the generic problem about 3c509 no tolerating foreign interrupts. weird is that sysreq works, but with about 30 sec latency. No oops onscreen. Looks like being in cycle somewhere. P75, 16MB memory, Compaq, PCnet32 onboard, 4x3c509B cards 3. SMP ACPI ? this is on server box. Dont know where it is, but once a day or so, after being away from computer, it wont be happy when I touch it again. Never happened while sitting there, allways when coming back. Sometimes X locks up, but most usually locks whole box. SysReq works, but it allways happnes on graphics console after display coming on and I have typed some letters into X screensaver lock password dialog. 4. performance problem: 10Mbit bridge with very minimalistic kernel is 20% slower with 8MB ram as compared to 16MB ram. Other interesting feature is, that it is 100% slower at start and after some minutes of run, comes to 20%... ultimately weird. kernel is 450kB compressed, has vfat as root fs, and whatever else possibly disabled. TCP is supported but real minimalistic. elmer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

It is a bit more generic. Just to get an automatic warning for each module which is marked experimental, so that I could rely on that, so I dont need to dig back 100 versions of source code.

from binary towards source level scalability

Couldnt see much else than half of it being implemented. 1. My point is more in source level scalability, whatever techincal way it is done. There is an natural potential for open source software which is not quite completely used. RedHat still ships i386 binaries which run 30% slower( and are still with debug info default on) than Mandrakes i586. Neither of them offers on-install automatic recompilation. Before imitation of commercial binary vendors they could think about using their native potential. 2. About macroplay, if you dislike it: if few macros would be used all over the code, it would be very clear, cleaner than without them. Ftape driver trace macros have some strings in them :), if strings are forced , then someone gets to comment his code a lot more. It is just a matter of getting used to style. 3. Lets assume for a while, that for every container(array, hash, btree) for which there is currently runtime dynamicly changeable default size or other parameter there would be a compile-time option to turn it static and compiled in with both intentions: a) to keep it small an operational on 386sx25(your cellular phone) and b) fast&memory-consuming on NxGB memory top-tuned SMP superbox. i.e. instead of #define MY_HASH_SIZE 123 or #define MY_HASH_SIZE ((whatever)->size) there would be CONTAINER_SIZE(MY, 10, user_min, 40, 123, 1200, user_max, 1) and it would by default compile to dynamically changeable 123, but could also be user-specified size or developer-specified minimum statically compiled in. And, would not go out of developer specified reasonable values. 4. symbol, printk and other text-based information, inline regulation... all of those disputes wheter to have or not to have something new like that in kernel could just end up being configuration options. PRINTK(subsystem, module, level, "my networking whatever") could be elliminated by configuration option like: not verbose for subsystem=networking. Top dream would be to have enduser to specify his intentions(file,webserving, desktop,development) and then a program gathering memory and cpu speed-size info, generating proper kernel and libraries config and compiling it static then and doing some stress test just after that.That could be standard procedure for linux installation :) Instead of compiling it by hand and then getting 30% faster. On some places source code must not be an art, but just systematic structure or a bunch of data in table. Currently, for example, inlining is an artistic act. And debugging. And /proc interface. The other way would be to make it a configure-time option and/or flexibly configurable/dynamicly changeable. Then it would be compile-time art for distributors. elmer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
kernel debugging
> understanding the
> > underlying principles and the code.
Speaking about that, I have been long time dreaming
about following strict standard template for linux kernel functions:
(macroplay intended)
--
INLINE(context,level,for_speed, fixed) returntype functionname
(PARM(parameters)){
DEBUG(ENTRY,SUBSYSTEM, module, functionname);
/* function body starts */
do something
do something
on success goto ok;
on failure goto failure_reason_name;
/* function body ends */
ok:
on ok do something
DEBUG(EXIT,SUBSYSTEM, module functionname, OK);
exit or return whatever
failure_reason_name;
on this reason do something
DEBUG(EXIT,SUBSYSTEM, module, functionname, reason_name);
exit or return whatever
failure_reason_name1;
on this reason do something
DEBUG(EXIT,SUBSYSTEM, module, functionname, reason_name1);
exit or return whatever
};
--
You see, you try to catch somebody by following their steps.
Instead, try to enchanche your own advantages.
Those two macros: DEBUG and INLINE would let the code be
generated as effective as possible and as debuggable as possible.
strict rule that all returns must be explicitly goto'd to the end would
make code also much easier to read and would force people to
formalize all failure reasons.
Closed source people have only one way to go, it is to make
kernel binary fully debuggable.
Imagine kernel configuration options: which subsystems
to optimize for speeed and which for size, for which to have
debug options turned on, etc. Different debug macros
for different situations - debugging, logging, timing.
All printk's made macros and configure-time option to dump
them all... that way the kernel may run in 2MB 386sx16 again
for embedded devices and have lots of inlines for 2MB cache
Xeon processors.
For to stay competitive, linux should less try to repeat others
tricks and more try to advance those, whitch are naturally its own.
Essentially the trick that everyone may recompile the kernel.

True multihead, lots of crashes
Hi, DUAL-Celeron, 2.4.0, ATI64 Rage pro AGP, Matrox Millenium, Matrox Mystique, ATI Rage II+ PCI, normal keyboard USB keyboard, 2x USB mouse. USB hub and USB hub in keyboard. 1. Just plain Xfree 4.0.2 with xinerama works stable, just gets killed by memory-hogging netscape. 2. framebuffer leads to hardlock sometimes quite soon. whatever, ati or matrox. Looks like at VT switch. No way to debug, 3. I have here second patched Xfree, got someones patch and rebuilt rpm, to support USB keyboard. the box crashes also without it. It looks like all places where VT switch may occur, are commented out from xfree. Without framebuffer, everything works, but vt switch still occurs and only one X is usable... first X stalls until second gets killed and then works again. sometimes I can even switch between them from console. Does the console input trigger console switch... dont understand. strace doesnt show anything ... looks like two copies of X talk each other via shared memory or something... elmer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
atyfb,matrox hardlocks, multihead, USB broken, 2.4.2-ac8
2.4.2-ac8, with 4 graphics cards, Dual Celeron now with 2.4.2-ac8 it is even more clear any attempt to insert module ends with straight lockup video mode swithc occurs and then ping to the box stops immediately. more, starting X locks kernel the same way. meantime I changed from BIOS the AGP to be primary video. this was probably what made the most of difference as AGP is with largest PCI ID. USB is also nonworking. 2.4.0 was most part OK. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
Re: atyfb,matrox hardlocks, multihead, USB broken, 2.4.2-ac8
Got it to work somewhat... that was real long f*** the only sequence - no dga, kernel boots and BIOS uses Matrox PCI as first graphics via matrox start up two ATI cards(one AGP, one PCI)(xinerama mode, screwed output ) with Xserver hacked to read /dev/input/event* ant talking direct to ATI. now insert matroxfb_base now start two normal XFree86 on framebuffer /dev/fb0 and /dev/fb1, i.e. matroxes, xinerama keyboard from system console... log into matroxes ATI dualscreen picture clears itself by magic spell and becomes usable. everything works... until ATI exits, then there is kernel hardlock. Weird that all locks are hardlocks - no ping no sysreq... SMP here. ah - message from matrox framebuffer - complaining no irq A assigned to slot, and suggesting that BIOS is buggy. Will I be more happy when using a dualhead matrox AGP instead of AGP+PCI ATI pair ? 2.4.0 kernel, 2.4.2-ac8 USB looks like very very broken. elmer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
2.2.16, 2.4.*, harddeadlocks with XFree86 and framebuffer
So, the problem is on different hardware and kernel versions. 1. looks like VT switch with multiple X copies running hangs on certain conditions 2. More critical: Matrox G400 dualhead AGP 16M hangs immediately with fb. Tested computers: 1. Tyan 230 SMP Dual PIII 667Mhz , 512MB 2. MSI SMP Dual PIII 667Mhz 512MB 3. Tyan 1834 SMP Dual Celeron 256MB Software: 1 compiled: 2.4.0,2.4.2,.2.4.2-ac8 2 RH7 stock: 2.2.16 1. True multihead hang on computers 2, 3, both software : First, to get it fly: I must log in via network, because executing X behind X/console causes vt switch. First I run USB keyboard patched X for ATI cards, non-fb. That one I can run forever, normally, until: if to execute matrox (two cards : Millenium + Mystique) server, it hangs or wont work if I modprobe matrofb_base, then now I have single possibility to run Xfree86-4 _once_ for matrox fb. If either of X's(for two matroxes or ATIs) quits, there is hardlock. ping stops, capslock doesnt work(for console keyboard, USB one naturally doesnt work at all), 2. Single dualhed G400 hang, on computers 1 2 3, software 1,2 . Well, it is simpler, it hangs with framebuffer and with normal X mode, with 2.2.16 and with 2.4.*, quite soon. inserting framebuffer module hangs the beast. framebuffer matrox compiled into kernel does not hang until I try to start X in some ways or do other console change/swtiching operations... Actually, RedHat 7.0 doesnt install on SMP Matrox dualhead G400 as XWindows setup probe lock the box up. It looks like I should tear it down and use old nfsroot based Xtermian again... And sell G400, with which there is nothing to do. Pity, everything works, but once a day ATI XFree86 sucks some dust in and gets killed and the whole box goes with it., cant stand it...

Ok, after 1. upgrading redhat gcc 2. applying that BKL in vmtruncate minipatch now it copies about 50MB before cp gets stuck on do_journal 2.4.0 with reiserfs patch and reiserfs quota patch just works (not the quota part yet). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Re: aironet4500_card (2.4.1-ac8), The PCI BIOS has not enabled thisdevice!
Sorry, no time to test, neither I have cisco cards. However, general notes: 1. Aironet did (cisco may do) weird tricks on bus. 2. insmod driver -> leds go out, that may be normal. ifconfig up should bring leds on. 3. People who fail with both drivers (Bens and mine), have had weird BIOS or BIOS settings in most of cases. IO conflict with bios configuration port (ICL 486 ), old PCI BIOS (Intel Pentium 200Mhz board) , etc. elmer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

Re: Aironet doesn't work
the whole pcmcia does not work in 2.4. Not with latest cardmgr. What makes airo_cs to work is that pcmcia package and kernel modules are replaced. That is what most of distros do. Which overwrites kernel standard ones and really fucks things up for pcmcia drivers being in kernel.
