Add topology description to the virtio-iommu driver and enable x86 platforms. Since the RFC [1] I've mostly given up on ACPI tables, since the internal discussions seem to have reached a dead end. The built-in topology description presented here isn't ideal, but it is simple to implement and doesn't impose a dependency on ACPI or device-tree, which can be beneficial to lightweight

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 patch series is the leftovers of a patch series sent in September 2023 [1] in an attempt to get some of the patches landed finally. This patch series originally came about after a _long_ discussion between me and Maxime Ripard in response to a different patch I sent out [2]. As part of that discussion, we realized that it would be good if DRM drivers consistently called

This patch series came about after a _long_ discussion between me and Maxime Ripard in response to a different patch I sent out [1]. As part of that discussion, we realized that it would be good if DRM drivers consistently called drm_atomic_helper_shutdown() properly at shutdown and driver remove time as it's documented that they should do. The eventual goal of this would be to enable removing

This series adds support for probing platform devices on Nouveau, as well as the DT bindings for GK20A. It doesn't enable the GPU yet on Tegra boards since a few extra things need to be supported before that. This version is mostly identical to v2 but fixes an important issue: the drvdata must be set to the drm_device for sysfs to work, so the platform device structure now includes the

This series adds support for probing platform devices on Nouveau, as well as the DT bindings for GK20A. It doesn't enable the GPU yet on Tegra boards since a few extra things need to be supported before that. Thanks to the input received for v1, this version is more self-contained and shares less stuff between nouveau_drm and nouveau_platform. The major change is that nouveau_platform is now
