Hi all,
this implements the last missing bits for softpin aka putting userspace in charge of the GPU virtual address space. This builds on top of the per-process address space series. As this is quite a stack of patches now, I'm providing a git branch [1] with all the necessary patches. Please note that I have not yet worked in the feedback I got for the per-process address space patches.
The corresponding userspace bits can be found at [2]. The Mesa changes always use softpin where possible and now finally allow GC7000 support to work with a non-horrible UAPI interface.
Regards, Lucas
