From: Thierry Reding <treding at nvidia.com> Hi Ben, these are a couple of patches that are in preparation for adding GV11B support. The fundamental issue that these are trying to solve is that the GV11B is the first Tegra incarnation of the GPU where the aperture really matters. All prior generations would accept any of them. For dGPUs we usually allocate memory in VRAM, so the default

The goal for this series is to introduce the hmm_pfn_to_map_order() function. This allows a device driver to know that a given 4K PFN is actually mapped by the CPU using a larger sized CPU page table entry and therefore the device driver can safely map system memory using larger device MMU PTEs. The series is based on 5.8.0-rc3 and is intended for Jason Gunthorpe's hmm tree. These were

From: Thierry Reding <treding at nvidia.com> Hi, the GPU on Jetson TX2 (GP10B) does not work properly on all devices. Why exactly is not clear, but there are slight differences between the SKUs that were tested. It turns out that the biggest issue is that on some devices (e.g. the one that I have), pulsing the GPU reset twice as is done in the current code (once as part of the power-ungate
