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.
Sumudu
