What kernel version, distributions, etc. are you working with?

Subject: QUES: serial line, select stalling
Date: Sat, 29 Jul 2000 15:06:06 GMT
Hi. I had successfully used select() for many years under the
proprietary LynxOS (TM) and fairly well under linux, but I find that
select() stalls and never exits on the serial lines if called again
too quickly. I am using a zero timeout time. I can prevent the
problem by putting in little delays so that select() is not called
again too soon, but this is too slow because the minimum delays is too
long and the animation application calls it very frequently (don't
ask, it's a port from DOS and I can't change the big interfaces yet).
The animation is too slow. Obviously, the DOS application original
had to multi-task by itself and periodically check the serial line
because DOS can't multitask (I don't know why they didn't use
interrupts, maybe the commercial serial library couldn't do it).
My options are:
1. Re-read everything on select to see what I missed (e.g., the
timeout value might be changed after the call of select() kind of
thing).
2. Change my ported-from-DOS serial line library to start a thread to
do blocking reads on a serial line and put the read data into a FIFO
or ring buffer. This is what I'm going to do on Monday. Then
check of the ring buffer should be low-cost.
3. In a year or two change the application's large partition
interfaces so that the animation app has a thread to do just animation
that communications with a thread that does blocking reads on the
seria line, using whatever inter-thread communication mechanism, POSIX
events for no-cost checking, or a mutex-protected flag ("data
available"), etc.
4. Start instrumenting the select entry point in the serial driver
with printk's and watch it.
5. Take a vacation.
Why does select stall if called again too soon? Some semaphore not
signalled?
Thanks

"Pgfs" (Postgres filesystem) is an NFS interface to a PostgreSQL database;
unfortunately I don't have a pointer to it handy.

Subject: ISDN TA driver
Date: Sat, 29 Jul 2000 17:33:14 +0200
Hi everybody.
I have a Philips ISDN PCA 128 Modem, and as it's about 4 years old, I
can't get any support from Philips. They don't remember anything about
it.
It seems that there's currently no driver available for it under linux,
so I would like to write one myself. The problem is that I can't get the
specs of the card. I know that it uses a MB86701 PnP controller
(Fujitsu), a SAB 82525 HDLC controller (Siemens), and an AM79C32AJC ISDN
controller (AMD). I'd like to avoid having to redraw the schematic of
the card and try to understand how it works, so could anyone give me
some help ? Anything is welcome, either an idea or a more complete
solution.
I have a Win95 driver, but once again I'd like to avoid having to
dissassemble it and try to understand the assembly code.
The card is and ISA PnP (works fine with isapnptools), and uses the
following resources :
IO : 0x140 - 0x14F
IRQ : 3
Thanks in advance for your help.
Laurent

CFS (cryptographic filesystem) is also software that provides an NFS
interface, in this case a plaintext view to some encrypted files.

Hi there!
I have problems using gcc 2.95.2 which I bootstrapped on RH6.2.
System is AMD Duron on VIA KT-133 MSI-6330. LAtest binutils are used,
kernel is 2.4.0-test5.
During compile of XF4.01 some targets are not made and I can't find out
why. I have also problems bootstrapping gcc 2.95.2. Sometimes gcc
bootstrapped fine, another run right after this stopped with sig11.
XF4.01 does not build consistently.
The system has 100 Mhz SDRAMS which are, to reduce error possibilities
at the moment clocked at 66Mhz. The system uses very conservative
settings in the bios. The Duron is a 600Mhz one, which is not
overclocked.
Please see attached the logs I have taken from my system. The string2.h
warnings are extracted from make World >&World.log of the build of
XF4.01 as is the error log via a quick grep.
I have attached configuration files. Maybe I screwed up during the
upgrade from egcs 1.1.2 to gcc 2.95.2 or there is a missing link to
header or library files that I am not aware of that could possibly
explain my problems.
If I compile the kernel though, I do not have problems at all, even If I
run it several times in a row. Consistently I will get a working new
kernel.
Thanks for any tips / hints / pointings of my stupidness or else in
advance :-).
With best regards
Michael Meding
