Problem with memory mapping in ia64 server.
Hello friends,
Iam writing a driver for PCI-X based add on card in HP X-5670 server with RHEL-5(2.6.18-55EL) with 4GB RAM.
As per my requirement I dedicated 1GB RAM memory to OS by added mem=1024M argument line in /boot/efi/efi/redhat/elilo.conf file.
Now Problem is Iam unable read/write the BAR's addressess retrned by ioremap function.
These BAR's are the kernel level pointers by which we can access the PCI-X device.
Can any body tell me where i am doing wrong?
