Dear all,
I am new to this group as well as to the driver
development.
I am developing a PCI driver with the following
specification.
CPU : Intel
celeron M 1.4GHz
memory : 1GB
kernel : kernel
2.6.15-r1
swap :
4GB
my driver works well with 512M RAM but it gives an
error when I
use 1GB of RAM. Error occurs at ioremap()
function.
*ptr =
ioremap(base,length)
length here is
128MB
The error asks to increase kernel memory space with
vmalloc.
Then I gave vmalloc as a kernel parameter
(vmalloc=256M)
in grub.conf. it went well in this
way.
Is this the way to overcome this problem or is it
due to some other
problems?(old kernel etc.)
I can't update the kernel since the driver is being
developed for a
customer specific machine which is already
used.
Thanks in advance.
