One thing: would people stop sending me compiler samples? I *know*
|
|
that it is not in the current version of the C standard, and I know
|
|
there are people out there who think ANSI C, the 1990 version, is the
|
|
Word of God[TM], but all I did was mention that:
|
|
|
|
a) A number of C compilers support it as an extension,
|
|
b) It has been proposed for inclusion in a future version of the ANSI
|
|
C standard,
|
|
c) There have yet surfaced a *non-artificial* example of code that it
|
|
would break (which would, if such code existed, make (b) a Bad
|
|
Thing[TM]).
|
|
|
|
Please let's put this thread to rest.

I don't know the original question, as the article has not reached here
|
|
yet. In regards to the shared IRQ's, this is the dos standard, but does
|
|
cause rather large problems if you try to extract any reasonable pace
|
|
from two serial ports on the same IRQ.
|
|
|
|
The easiest (believe me, it is the simplest modification I've ever done
|
|
to hardware) thing to do is re-wire the serial boards - usually this
|
|
requires the addition of one wire and the removal of one jumper
|
|
connector, sometimes you also have to cut a track.
|
|
|
|
After doing this, you have to modify the kernel to use AUTO_IRQ,
|
|
CONFIG_AUTO_IRQ or change the flags on the first four com ports,
|
|
depending on kernel version.

Hi all.
|
|
This is my new trouble with Linux:
|
|
|
|
My setup: Slackware 1.1.2, kernel 1.1.53
|
|
I created a private directory (perm=0700) on a DECstation and mounted
|
|
it on my Linux machine via nfs. While reading and writing files works
|
|
fine, I can't execute anything.
|
|
|
|
The error I get is of the form
|
|
<shell>: <pgm>: Operation not permitted
|
|
This happens with bash,tcsh and ksh.
|
|
|
|
The fstab entry is:
|
|
<machine:/dir> <mydir> nfs rw,suid,exec,nodev,user,rsize=8192,wsize=8192
|
|
|
|
User and group ids are the same on both machines.
|
|
We performed tests between two DECstations and there were no troubles
|
|
executing files.
|
|
|
|
What do you think is best:
|
|
1) have a deeper look at the docs
|
|
2) declare this as a kernel bug in fs/nfs
|
|
3) upgrade to Slackware 2.0
|
|
4) get newest version of network code from the Net

If programmed-I/O mode works and shared memory doesn't, you have a hardware
|
|
conflict. The shared memory memory region 1) must not conflict with other
|
|
adaptors RAM *or* ROM 2) must not be shadowed and 3) must not be cached.
|
|
You've ruled out #2, but have you checked your BIOS setup for #3?
|
|
|
|
(BTW, programmed-I/O on the 3c503 is, uhmmm, "rather low performance" to put
|
|
it kindly.)

|

ARP on the remote machine because it looks at the address of the packet you
|
|
transmitted. You don't need bidirectional traffic! (I've used this as a
|
|
debugging data point -- if the remote machine knows the ethernet address,
|
|
the Tx packets are getting through.

I don't think that a new file system is necessary for this. An easy
|
|
way to accomplish this is to write a shell script run every night,day
|
|
,whatever(via cron). This script could check the amount of free space
|
|
left on the drive, and if necessary, destroy any .o files.

|

|
|
HI
|
|
|
|
>>> This is about kernel supported threads <<<
|
|
|
|
Intro:
|
|
|
|
To make clone viper-alike in order to test things and make
|
|
a client/server application during viper is under construction,
|
|
I added COPYPID option for clone syscall. This is for 32-bit
|
|
PIDs. COPYPID copies lower 16 bits of the PID which created the
|
|
clone, and puts the clone_id in higher part.
|
|
|
|
Example: process has PID = 128 = 0x80
|
|
When 0x80 forks itself, PID=0x81, 0x82 etc is created.
|
|
When 0x80 clones itself without COPYPID, it's the same.
|
|
When 0x80 clones itself with COPYPID set, then
|
|
PID=0x10080, 0x20080 etc is created.
|
|
|
|
With this, 32-bit modifications for /proc (procfs) have sense,
|
|
indicating clones of the process in a special way. That's
|
|
something like /proc/PID_BITS_0-15/vwp/PID_BITS_16-31.
|
|
|
|
Patched 1.1.52 runs great with all this together (including
|
|
/proc/mtab) for several days.
|
|
|
|
Also an early patch for kmem-ps is done to show 32-bit PIDs.
|
|
|
|
Some time is needed to adapt clone examples based on postings
|
|
from Rob Janssen and Michael David McCartney. If there are
|
|
newer versions, please lemme know.
|
|
|
|
Upload of everything spoken here to sunsite may be expected
|
|
soon. It will be something like vwprocfs-0.4.0-1.1.52, that's
|
|
actually /proc/mtab thing which has grown out :)
|
|
|
|
Next thing is try to port one server to work with clone.

Looking for: ------->

Growing stack for clone syscall would be nice. I am
|

interested did someone consider how to make it? Or
|

already has some patches that provide it? I'd appreciate

any info.

Whats to tell? The Linux FAQ lists no 68k mac ports,
|
|
|

Amiga and Atari posrts exist though.

Yeah. I have motif 1.2.2 and having to mess around with keeping the old
|
|
*.so*3* files around is kind of a pain. Not to mention trying to compile
|
|
something that uses the motif library, which wants the old *.sa* files.
|
|
|
|
Oh well, I guess such is the price of progress. Hopefully they'll recompile
|
|
the motif stuff real soon (and move up to 1.2.3 in the process).
|
|
|
|
(But still- many thanks to the XFree team, obviously...)

They even seem to have a member out patrolling this group for questions
|
|
(David Dawes?). It really is a class act.

SCSI-Scanner with Linux
|
|
|
|
Hi all,
|
|
|
|
does anyone have experience with using a SCSI Scanner
|
|
with Linux?
|
|
|
|
I have got a Mustek Paragon 6000 (it was just cheap :-)
|
|
and want to scan images under Linux. This isn't supported
|
|
in Linux kernel 1.0.9.
|
|
|
|
Has anyone written a device driver for this or has got any ideas
|
|
about how to do it (where do I get the vendor commands for it?),
|
|
is there enough interest to start writing such a module?
|
|
|
|
I would appreciate any comments to this case.
|
|
|

I'm preparing for another update of the Serial-HOWTO, and I was
|
|
wondering if anyone was working on intelligent serial board drivers
|
|
(besides the people listed in the projects map...). If so, please
|
|
let me know about it. If you are in the projects map, and would like
|
|
to add something, feel free.
|
|
|
|
For that matter, if you have anything to say about the Serial-HOWTO,
|
|
get in touch. I've redirected followup to me, because I'm really
|
|
busy right now, and blah blah blah. I'll summarize if there is interest!
|
|
|
|
Thanks,
|
|
Greg

In general, Linux's ext2fs is significantly faster than ffs. I don't

have hard performance data right beside me, but I can get it if you
|

like. From memory, ext2fs is typically 10% to 50% faster than ffs for
|
|
general use; some operations (such as unpacking a large tar archive) can
|
|
achieve a much greater speedup.
|
|
|
|
Talk about an understatement! I had noticed a big performance increase, and I
|
|
wanted to quantify it, so here's a comparison of unpacking the entire X11R6
|
|
distribution, applying the X Consortium patches, and then installing XFree86
|
|
3.1 sources. Both my Linux Pentium 90 system and the SparcStation were
|
|
unpacking onto 2.1gb SCSI drives:
|
|
|
|
SparcStation 10 Model 41 SunOS 4.1.3:
|
|
|
|
187.280u 200.810s 46:42.58 13.8% 0+177k 7801+123005io 2600pf+0w
|
|
|
|
Pentium-90 Linux 1.1.51:
|
|
|
|
121.460u 143.620s 9:49.53 44.9% 0+0k 0+0io 1197pf+0w
|
|
|
|
Yes, my Linux system did this five times faster than a SparcStation!
|
|
|
|
For the curious, here's a copy of the script that was timed above (GNU tar and
|
|
gzip were used on both machines, compiled by gcc for maximum performance):
|
|
|
|
#! /bin/csh -f

rm -f patch.log

Then why don't you take the sources for gnuplot and take out what you need?
|
|
|
|
Allow me to humbly propose PLplot. Available via anonymous ftp from
|
|
dino.ph.utexas.edu. Works great on Linux. Does what the original
|
|
poster wants. Does not require hacking gnuplot to shreds to do what
|

he wants, etc.
