How does Xfree coordinate PCI resource mapping with the Linux kernel? When I cat /proc/iomem or /proc/ioports none of my video hardware is assigned to a device driver. Is it possible for XFree to move the location of PCI resources? Shouldn't we add request_mem_region(addr, size, "driver") calls to the dri hardware drivers to tell the kernel not to map anything else on top of our addresses.
Standalone DRI needs to know the address/length of hardware resources in order to addmap them. A generic IOCTL could be added to provide the six pairs of address/length for PCI hardware. Another issue is mapping the ROM in long enough to read init values from it. I'd like to see if we can get a kernel call added to the PCI code to map/unmap ROMs. That way it could be done in a platform independent manner. This makes me think that XFree must be mapping the ROM in without the kernel's knowledge. ===== Jon Smirl [EMAIL PROTECTED] __________________________________ Do you Yahoo!? The New Yahoo!
