2020-08-05vdpa/mlx5: Add VDPA driver for supported mlx5 devicesEli Cohen
Add a front end VDPA driver that registers in the VDPA bus and provides networking to a guest. The VDPA driver creates the necessary resources on the VF it is driving such that data path will be offloaded. Notifications are being communicated through the driver. Currently, only VFs are supported. In subsequent patches we will have devlink support to control which VF is used for VDPA and which function is used for regular networking.

2020-08-05vdpasim: support batch updatingJason Wang
The vDPA simulator support both set_map() and dma_map()/dma_unmap() operations. But vhost-vdpa can only use one of them.

2020-08-05vhost-vdpa: support IOTLB batching hintsJason Wang
This patches extend the vhost IOTLB API to accept batch updating hints form userspace. When userspace wants update the device IOTLB in a batch, it may do: 1) Write vhost_iotlb_msg with VHOST_IOTLB_BATCH_BEGIN flag 2) Perform a batch of IOTLB updating via VHOST_IOTLB_UPDATE/INVALIDATE 3) Write vhost_iotlb_msg with VHOST_IOTLB_BATCH_END flag Vhost-vdpa may decide to batch the IOMMU/IOTLB updating in step 3 when vDPA device support set_map() ops. This is useful for the vDPA device that want to know all the mappings to tweak their own DMA translation logic. For vDPA device that doesn't require set_map(), no behavior changes. This capability is advertised via VHOST_BACKEND_F_IOTLB_BATCH capability.

As Thomas noted "... there are right now too many places in IP27 code, which assumes NUMA enabled", the simplest solution would be to always enable NUMA for SGI-IP27 builds.

There is nothing too exciting in it, but a new macro that fixes a build failure on a minor ARM32 platform that appeared yesterday is part of it so we better merge it. Core changes: - Introduce the for_each_requested_gpio() macro to help in dependent code all over the place. Also patch a few locations to use it while we are at it. - Split out the sysfs code into its own file. - Split out the character device code into its own file, then make a set of refactorings and improvements to this code. We are setting the stage to revamp the userspace API a bit in the next cycle. - Fix a whole slew of kerneldoc that was wrong or missing. New drivers: - The PCA953x driver now supports the PCAL9535. Driver improvements: - A host of incremental modernizations and improvements to the PCA953x driver. - Incremental improvements to the Xilinx Zynq driver. - Some improvements to the GPIO aggregator driver. - I ran all over the place switching all threaded and other drivers requesting their own IRQ while using the core GPIO IRQ helpers to pass the GPIO irq chip as a template instead of calling the explicit set-up functions.

2020-08-05selftests/net: relax cpu affinity requirement in msg_zerocopy testWillem de Bruijn
The msg_zerocopy test pins the sender and receiver threads to separate cores to reduce variance between runs. But it hardcodes the cores and skips core 0, so it fails on machines with the selected cores offline, or simply fewer cores. The test mainly gives code coverage in automated runs. The throughput of zerocopy ('-z') and non-zerocopy runs is logged for manual inspection. Continue even when sched_setaffinity fails. Just log to warn anyone interpreting the data.

2020-08-05net: dsa: sja1105: use detected device id instead of DT one on mismatchVladimir Oltean
Although we can detect the chip revision 100% at runtime, it is useful to specify it in the device tree compatible string too, because otherwise there would be no way to assess the correctness of device tree bindings statically, without booting a board (only some switch versions have internal RGMII delays and/or an SGMII port). But for testing the P/Q/R/S support, what I have is a reworked board with the SJA1105T replaced by a pin-compatible SJA1105Q, and I don't want to keep a separate device tree blob just for this one-off board. Since just the chip has been replaced, its RGMII delay setup is inherently the same (meaning: delays added by the PHY on the slave ports, and by PCB traces on the fixed-link CPU port). For this board, I'd rather have the driver shout at me, but go ahead and use what it found even if it doesn't match what it's been told is there.
