Michael - If you've got a Mach64 and you want it mainstream you need to add code which validates the command stream passed to the chip is valid. There is code like this in the VIA driver and the Mach64 needs something similar to verify you aren't doing things like DMAing patches into the kernel with the graphics card but only using commands that are "safe". --- This SF.net email is sponsored by: Splunk Inc.
