It appears that the i915 family driver used to insert the mtrr in older kernels and returns in the latest drivers in the 2.6.30-rc series. It appears that the current driver only inserts the mtrr when GEM is being used. Had a go at backporting the fix for this from upstream. I have built kernels

I think that message "no space left on device" means your MTRR registers are all used up. (There are only eight of them.) To check whether MTRR cleanup is enabled, you can run "dmesg | grep MTRR". The cleanup process produces the lines "original variable MTRRs" and then "New variable MTRRs" (as

Having looked into this further, I find that adding the kernel boot parameter "enable_mtrr_cleanup" does exactly what I'd done in replacing the 4GB entry, and for the same purpose (opening up a range where a new write-combining entry can go). Plus, it's a general algorithm, not something specific

That error message "write error: invalid argument" doesn't mean that there was a syntax error. Instead the kernel is rejecting the command. In my case it added a line to dmesg explaining the rejection: mtrr: type mismatch for d000,100 old: write-back new: write- combining That was becaus
