segfault on create_workqueue(...)

2004-08-20T10:51:50Z

Hello,
I apologize for my amateurish question, but I don't understand the
reason why my simple module won't run. On 'insmod ./wq_test.ko' I
always get the segfault. I was trying to get my first workqueue
working but without any success. The code is here:
...
static struct workqueue_struct *wq_test_workqueue;

64-bit Data PCI Bus Transactions

2004-07-08T01:03:34Z

Anyone know of any recourses discussing how to force a 64-bit data word on a
PCI bus? We are using a Tyan motherboard with AMD64 processors. The slots
are PCI-X. While DMA operations which appear to originate from the PCI SCSI
controller are 64-bits (data) wide, code written to write to a memory mapped

Help on how to redirect printk from syslog to GNNOME terminal

2004-01-05T14:41:36Z

I have tried to use the following code to redirect the printk to

xterm and not in char mode or the console really means to be RS232
terminal. Please help.

fprintf(stderr,"%s: ioctl(stdin, TIOCLINUX): %s\n",

preferred way to load module at boot time?

2003-12-05T00:38:30Z

I've written a module for accessing a PCI card and I would like it to
load automatically at boot time. I know i can simply add a modprobe
command to my rc.d, but I'm wondering if I can get the hotplugging
framework to load it for me. I've read what I can find about this,
but I havent been able to get it to work, what is the minimum

Device Driver & Interrupts

2003-11-08T13:29:53Z

Hi. I've done a lot of RTOS (VxWorks and VRTX) and NON-RTOS work creating
device drivers; i.e., working at the hardware interfacing level. I've also
done some real-time UNIX work and some Linux Embedded application
development, but I've never worked at the device driver level w/ either of
these OS's. In general, I have been told that it is much more difficult to
