Hi,
Back in v3, this patch series was turned down due to community
policies regarding i915 GEM development. Since then, I have
received several requests from userspace developers, which I
initially declined in order to respect those policies.
However, with the latest request from UMD users, I dec
Hi Linus,
It appears that the fd.o infrastructure is back enough to facilitate
