[PATCH 0/3] New instmem implementation for Tegra
Due to the lack of implicit synchronization between CPU and GPU on Tegra systems
(like what PCI provides for dGPUs), the instmem implementation of GK20A/GM20B
relied on the slow, legacy PRAMIN so that CPU accesses used the same path as
GPU, making sure we see the same data on both ends.
The recent Nouveau refactoring introduced acquire/release functions on instmem
that help us understand the
