I am writing a linux kernel driver for a custom pci device. I am developing against the stock fedora 6 kernel on an x86. This device has 512 MB of IO memory reserved by BAR 3. Whenever I try to ioremap this space I get the error:
allocation failed: out of vmalloc space - use vmalloc=<size> to increase size.
I think I understand why this is happening. I obviously don't have enough vmalloc space to map such a large chunk of memory. I have been using Corbet's et el's "Linux Device Drivers", Love's "Linux Kernel Development", and many websites as a guide in this development process but have yet to come across information that will help me.
I'm curious if there is a way around this issue. Or a better way of handling it so that I can properly map the entire io memory space.
Thanks for any help, Jon
