From: Yonatan Maman <Ymaman at Nvidia.com> This patch series aims to enable Peer-to-Peer (P2P) DMA access in GPU-centric applications that utilize RDMA and private device pages. This enhancement is crucial for minimizing data transfer overhead by allowing the GPU to directly expose device private page data to devices such as NICs, eliminating the need to traverse system RAM, which is the

This is a complete rework from the last version I sent out. Now the implementation is more centered around the power_rails we find in the SENSE table instead of extdev centered. This makes the implementation a lot easier and straightforward. I've added support for the INA219, INA209 and INA3221 sensors found on multiple Fermi and Kepler cards, but only the INA3221 bits are tested so far.

These 4 patches fix two issues that existed on Tegra regarding DMA: 1) The bit indicating whether to use an IOMMU or not was hardcoded ; make this a platform property and use it in instmem 2) The DMA mask was not set for platform devices. Fix this by converting more pci_dma* to the DMA API, and use that more generic code to set the DMA mask properly for all platforms. Tested on both x86

this series makes use of the load counters we can use to get information about the current load of the gpu. This series includes the needed pmu bits and a debugfs interface to read them out. Currently the values are between 0 and 255, because it is much easier to implement it this way on the pmu. Karol Herbst (4): subdev/pmu/fuc: add gk104 pmu/fuc: add macros for pdaemon pwr counters
