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

Hello, this patch series adapts the platform drivers below drivers/gpu/drm to use the .remove_new() callback. Compared to the traditional .remove() callback .remove_new() returns no value. This is a good thing because the driver core doesn't (and cannot) cope for errors during remove. The only effect of a non-zero return value in .remove() is that the driver core emits a warning. The device

This patch series is the final (?) step towards the initial support of GK20A, allowing it to be probed and used (currently at a very slow speed, and for offscreen rendering only) on the Jetson TK1 and Venice 2 boards. The main piece if the first patch which adds platform devices probing support to Nouveau. There are probably lots of things that need to be discussed about it, e.g.: * The way the

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

Hi, This series includes some pieces of fixes to complete the GK20A power on/off sequences and add the suspend/resume support. The patches 1/11 - 4/11 are based on the linux-next-20141219. The patches 5/11 - 11/11 are based on the branch "linux-3.19" of Ben Skeggs's tree (http://cgit.freedesktop.org/~darktama/nouveau). Thanks, Vince Vince Hsu (4): (linux-next-20141219) ARM:

Changes since v3: - Use a single dma_attr for all DMA-API allocations in instmem instead of one per allocation - Use device.info.ram_size instead of pfb->ram to check whether VRAM is present outside of nvkm Changes since v2: - Cleaner changes for ltc - Fixed typos in gk20a instmem IOMMU comments Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into
