I'm tasked with writting a driver that allocates a 4M chunk of memory for I/O & DMA, between 63M-67M. The hardware I'm coding for, is a pci<>pci bridge that allows communication from one system's memory bus (host) to another system (target). This communication is actually performed both ways. I have the system currently working, but I have to limit it to 60M memory at boot time to enable this buffer. I'd like to be able to use the full range of memory. I've tried looking at other source code examples, but none exist for this particular instance. I have a function call in Win2K that works exactly this way if the driver is loaded on boot, but I need it for linux. I'm using 2.4.9-40 (Redhat 7.2 updated) kernel. -- Tobin B Davis <tobind@ichips.intel.com> -- Kernelnewbies: Help each other learn about the Linux kernel.
