Hello,

I've stumbled upon a problem trying to get a NVIDIA 7300 SE together with my K9VGM mobo, a problem "pci=nommconf" or other grub parameter could not solve with a 2.6.27-11 kernel.

The symptom was a flow of "+------ PCI-Express Device Error ------+" at boot time when plugging the video card in:

The /etc/inittab file on board, contain the one line given below,
"::respawn:/sbin/getty -L console 0 screen"

So,what is the meaning of "console" & "0" in this line.
screen is the value of my TERM environment variable.

So, Please tell me, what is the use of "console" & "0" here.

Thanks in Advance

Is it possible to setup a user account on a linux box, so that when that user logs in via FTP, he can only access files in their home directory? not in /usr or /tmp etc... directories.

Linux: Fedora-10 ARM

I am glad to announce the availability of Fedora 10 ARM.

Fedora-ARM is an opensource project which provides support for ARM as a secondary architecture in Fedora.

This implies you could run all the packages within Fedora-ARM on your ARM processor. Fedora-ARM 8, which was announced earlier, has support for almost 9000 packages within Fedora. While Fedora-ARM 10, which was recently announced, has support for more than 2000 packages and growing.

The packages have been built for ARMv5 EABI, soft-float, little endian (armv5tel).

The best way to get started is to download the pre-built RFS image and load it up on your QEMU instance or your ARM processor.

The Fedora-ARM wiki has further more information.

Hi everyone,

I use the following link script file.
The section ".text.sram"'s execute-address is different from load-address.

If I execute arm-elf-ld, then the following warning is occurred.
=> warning: dot moved backwards before `.data'

The section ".data"'s execute-address is less than the section ".text.sram"'s one.
But their load-address is different each other..

Switching from X-Window to VT

Hi,

I have a question regarding switching from X-Window to virtual terminal. Usually I use both of them and I often switch between of them.
I wonder why does the switching from X11 to VT take so much time, while switching in opposite direction takes place almost immediately.

Userspace handling of driver interrupts

I am writing a driver to handle a network device on uClinux.

For reception of Ethernet frames, the interrupt handler receives the frame from the hardware, then it gets passed up and dealt with by the higher layers of the TCP/IP stack, so we do not have to do anything in user space.

Allowing a process to write to a single directory only

Hi,

I am trying to find a way so that regular users could run untested applications safely.I am not really worried about applications reading stuff they should not, but I _am_ worried about them creating a mess where they have no business writing.

Is there a way to restrict the capabilities of a process and its children so that they can only write under a certain directory ?
