Hi, The IXP1200 hardware manual gives the memory map of the IXP1200. Can ioremap be used to map the physical addresses given into the linux kernel's address space ? Kamesh.
Yes. In fact, the pciDg driver that is part of the SDK already does this (it does not map this into userspace address spaces yet, but you can add this easily also). HJB Kameswara Avasarala wrote:

Hi, Thank you. Is it possible to map any region in the memory map into the SA Linux kernel in this way ? For example the Transfer Registers of the micro engines ? Kamesh. Herbert Bos wrote:
