Hello,
A bit confused with "free Linux/Ubuntu VMs".
Do you mean you looking for VM image ( to directly run your tests )
or an emulator to create VMs locally and play around.
For the first, I have not tried with. Probably vmware images can be found at :

Hi,
There is an old bug come up while migrating from 2.6.18 to 2.6.33The
interrupts were generating correctly
in 2.6.18 where the interrupt was registered using SA_INTERRUPT then while
migrating to 2.6.33 this has been changed to IRQF_DISABLED this is the
only change in migration... after doing
code (like lsusb.c
etc )..
Thanks ,

Hi All,
As part of diagnostics I have to make sure the USB controller is
configured correctly.
Can I get this information from any entry in /sys or /proc ?? If yes where
??
If no I plan to add a exclusive entry in the driver to do my diagnostics.
Is that feasible by reading some of the reg

Hi All,
I have a I2C chip driver,and there are two identical chips on two
different i2c bus.
I have registered the driver and initialized it and created two nodes
/dev/chip_0 and /dev/chip_1
If I open the node from user how will I make driver identify which device
to access .ie in the ioct

Hi All,
I have a situation where I have to lock the ioctl provided in my driver. I
have a uni processor (ARM) system.
I am using Mutex as the lock for my ioctl.
DEFINE_MUTEX(&lock_ioctl);
MyIoctl()
{
Mutex_lock(&lock_ioctl);
Switch(){
...
}
Mutex_unlock(&lock_ioctl);
return 0;
}

Hi,
I have an embedded system on which i get crash (Caused by memset ) at long
run( Reproducible 2/10 times ),
I wanted to know efficient ways (materials) to handle memset crashes .
*Program terminated with signal 11, Segmentation fault. *
#0 memset (dstpp=0xd2, c=, len=3374)

Dear All,
I have a kernel module which i want to add to kernel permanently(I was
doing it dynamically) .
How can we achieve this ?
