Would it be possible (not extremely difficult) to use
Windows drivers under Linux? As there seems to be some shortage of them
(for example USB scanner drivers or some new GFX cards), it would be
a nice short term solution to be able to use existing Windows drivers.

I just did a "so-called" "upgrade" from RH 6.2 to RH 7.0 and I found that even
the Redhad provided SRPM for the installed kernel (2.2.16-22) would not compile
without errors. I grabbed a fresh 2.2.17 from www.kernel.org and I has the
same "pasting" problem as well as other problems.
The fix I found that permitted flawless compilation of the 2.2.17 kernel and
modules was to change the gcc to kgcc as follows:
HOSTCC = kgcc
and
CC = $(CROSS_COMPILE)kgcc -D__KERNEL__ -I$(HPATH)
The kgcc was already installed on the 7.0 system.
Although I have been able to compile two different kernels and a realtime-linux
patched kernel, I havn't been able to compile much of anything else and have it
work.

You won't find one single tool for this...
There are several debuggers based on GDB; look for DDD, Insight FE, Code
Medic, kdbg, HP Wildebeast.
There are also a number of "IDEs" somewhat in the style of that
introduced by Borland, including XWPE, RHIDE, Source Navigator,
WipeOut, Code Crusader, KDevelop.
Vis-a-vis editing/compiling software, it is common for programmers
to wish not to be dependent on the availability or lack thereof of
a particular "IDE"; it is common for programmers to be capable of
coping with the lack of any graphical environment whatsoever. This
is quite critical if you're trying to work with the kernel; there
may well not be enough of the system functioning to allow you to
have a GUI at all, and debugging in the kernel is Rather Special...
It is not uncommon to use GNU Emacs as an "IDE on Steroids;" combining
it with "etags" provides consider power in editing code...

Date: Mon, 09 Oct 2000 10:56:32 +0800
Hi ! All
While writing a module, sometimes there is a need to access some kernel
symbol that is not exported , it is, can not be found in /proc/ksyms.
Say , the global variable : main_table . Practically, it can be handled
by directly accessing /dev/kmem. But, is there any other ways to do that
?
Thanx .

The GPL is less restrictive (and more comprehensible) then the Qt1 license.

In particular, it eliminates all the confusion about the KDE license (much
of which was due to misunderstandings of copyright law by many Debian
developers, but that is irrelevant now).

I don't know what "bluster" you are referring to, but if "pragmatic" means
"I want to use Qt in a closed source project", I don't see why you
shouldn't have to pay Troll.

Subject: Network Drivers help!
Date: Mon, 09 Oct 2000 11:33:53 +0300
Hello everybody
Although I already have some experience in char device drivers, I
feel lost as far as network drivers making is concerned.
My current task is to create an HDLC driver for linux. (I'm going to
use the on-chip capability of PPC860 for that). From what I have seen
from the kernel sources, the socket abstraction that is used for the
network
drivers seems to add awful lot of complexity and overhead. Given that
I'll be using it in an embedded set-up, this is an issue.
I would like to know if there is any way to avoid doing all this
fuss with the sockets. An idea that crossed my mind was that I may use a
character device driver to do the job. I know that this will be a char
rather than
packet oriented solution, but with some additional effort it will be OK.
Later I will be using write()s and
select()s from a user program to communicate with the driver. I wonder
whether I'm missing something
here, beyond any aesthetic issues of course.
If I eventually have to make a network driver, I would like somebody
give me some pointers. For example,
I miss issues like, how I can use the driver's functionality from a user
program (is it only through sockets using SOCK-RAW type?), or attach a
home-made protocol functionality, or how I can use ioctls (as long as
there
are no /dev/... file to operate on), etc. etc. I'm afraid, the otherwise
perfect book by Alessandro Rubini doesn't
cover network drivers in as depth as I wished. In the net, the
references are poor too... Are there any books
that cover this topic?
Thanx in advance for you help

Date: Mon, 09 Oct 2000 13:24:37 GMT
What's the best way to get proprietary notifications from networking device
drivers? I need to get notification data through ioct-interface but I need
someway to signal that data is ready. What is the best way to accomplish
such thing. The only way I can think of is to put pending request from
user-mode to kernel-mode and release it from driver every time when
something happens. Can anybody think of anything else?

Subject: PCI Card access problems (driver)
Date: Mon, 09 Oct 2000 16:29:12 +0200
Hi,
I try to develop my first linux driver but ran into some problems. The books
I have and online docs I've found couldn't give all answers so I hope you
can :-)
1. I have the address of the card, 0xe300000. With ioremap() I get a remapped
address, e.g. 0xc800..... Can I directly access data (pointer dereference)
with that remapped address? Which of the addresses do I have to use with
readb/readw/readl? I guess it's the latter one because the 0xe300... caused
page faults?
2. This card uses 64MB PCI memory. After remapping, different access methods
only returned 0xff for all probed values in that 64MB area. I have seen
that other programmers use mem_map_reserve() for the PCI memory area. Is
it neccessary in my case? I tried it but nothing changed.
3. A HowTo at TUCOWS described that writing all 1's into a base address
register and reading again gives the size of the mapped PCI memory. This
procedure was not for i386 architecture. Testing on my i386 produced
wrong sizes. Is there a chance to check the size, so that I can use this
value for ioremap()? (There are two versions of that card, one with 64MB
and one with a reduced mem. size of 64KB)
Thanks in advance!
Heiko.
P.S. The mentioned card is a PCI-60A IndustryPack(TM) holder with a
PLX PCI9080 PCI controller chip. Maybe anyone has already heard about
that... :-)

Hi all,
I installed Suse Linux 6.4 and when I try to port a piece of code, I get
problems with the shared memory implementation. The linker doesn't find
the shm_open (open a shared memory object (realtime))function.
Any idea what package I have to install to resolve that problem
(shm_open is not in mman.h)? The funny thing is that 'man mmap'
references to shm_open (mmap is declared in sys/mman.h), while there is
no 'man shm_open'.
Thanks in advance,
Jan.

We have ported the BSD timeslave to Linux (Debian slink, kernel 2.0.36)
and adjtime definitely works *in that context*. But we have learned that
adjtime is one accursed API. On many OSes, it is either undocumented
(and Linux is one instance, where did you find the doc on your system?),
or does not work as the %&#$ doc says (e.g. SGI). On Linux, one crucial
line is in <kernel_src_dir>/kernel/sched.c, variable "tickadj". It reads
int tickadj = (500/HZ ? : 1);
in our sources (actually, we run timeslave on a tight leash, every 30
secs, because we need it, and we had to increase tickadj to 20 times
that). Do you have the same? What is your HZ? How did you discover the
clock is not updated?
Now, adjtimex, *that* one is tough! I haven't been able to understand
what it does, and its relation with the kernel PLL, or how the latter
works... so I'm still not able to use adjtimex.
