(http://www.ramix.com) to be used in a telecommunications project here at Nortel Networks. Originally I had planned on implementing the entire driver as the lowlevel driver and the block device driver as well untill someone on the kernel mailing list pointed me to this project. Anyway .. The PMC551 PCI Memory module is for cPCI (CompactPCI) systems. Basicly it's a PCI device with a bank of dram/sdram that can be accessed just like normal memory once you have initialized the device. Since the memory on this device is crossing the PCI bus we chose not to implement it in a fashion where it got mapped into system memory for performance reasons and decided it would be better suited to to be used as a block device and mapped off as either swap space or as a ram drive for use in the project, as the systems in the project have no hard drives. Anyway .. I have downloaded the mtd tarball and been looking through the documentation, and about to hit the source, and was curious if anyone had some pointers as to where I should start in hooking the low level module into the rest of the system so as to short-cut a headache. Any information (docs, hints, tricks, chickens I can sacrifice over the cards and voodo rituals) that would help to get this going quickly would be much appriciated - - -- Mark Ferrell : mferrell@nortelnetworks.com (972) 685-7868 : Desk (972) 685-4210 : Lab (972) 879-4326 : Pager To unsubscribe, send "unsubscribe mtd" to majordomo@imladris.demon.co.uk
