Hi everyone, is is the sixth incarnation of this set of patches. It enables device drivers to resize and most likely also relocate the PCI BAR of devices they manage to allow the CPU to access all of the device local memory at once. This is very useful for GFX device drivers where the default PCI BAR is only about 256MB in size for compatibility reasons, but the device easily have multiple gigabyte of local memory. Noteable changed compared to v5: 1. Added some rb. 2. Followed Andy's suggestion on patch #3 to use a next pointer to make it more readable. Mostly every comment addressed now, so next question is how we want to merge this upstream? I would suggest patches #1-#4 through some PCI branch and we send #5 through the drm maintainer as soon as the dependencies are accepted? Thanks for all the help, Christian.
