DRM: tegra_udrm: Add tegra_udrm DRM driver 2019-01-09T08:16:57+00:00 yogishk yogishk@nvidia.com 2018-11-20T14:05:53+00:00 647118deb4c0682d1205e4707c4bc6759e05c2ff Add skeleton for tegra_udrm DRM driver. This driver adds Kernel DRM support for user mode DRM driver on NVIDIA Tegra Soc. OSS DRM clients (e.g. Wayland compositors) expects DRM driver node like "/dev/dri/card0" and they do raw open()/close() on this node and pass the obtained fd to UMD (in our case libdrm_nvdc.so). Clients also tends to do poll()/read() and mmap(). To support this tegra_udrm registers with DRM framework and provides following ioctls - DRM_IOCTL_TEGRA_UDRM_DMABUF_MMAP : To support mmap(), UMD issues this ioctl to send dmabuf fd to the driver. Driver will return offset which user space can use in mmap(2) on tegra_udrm device fd. DRM_IOCTL_TEGRA_UDRM_DMABUF_DESTROY_MAPPINGS: Clear stored dmabuf fds and offsets. DRM_IOCTL_TEGRA_UDRM_CLOSE_NOTIFY : In order to know when DRM client has called close() on driver fd, UMD issues this ioctl with eventfd. This eventfd will be signaled by the driver in .preclose method. When clear field in ioctl arg is set, driver will no longer signal this eventfd. DRM_IOCTL_TEGRA_UDRM_SEND_VBLANK_EVENT: DRM clients do poll()/read() on driver fd to get vblank/pageflip events. To dilever this events to clients, UMD issues this ioctl with vblank event. Driver injects this event in DRM framework. To prevent user-space from unintentionally inserting tegra_udrm.ko, we add modeset module parameter.

This patch adds the following NVLINK drivers: - Tegra NVLINK endpoint driver: - Each endpoint driver is respondible for programming the HW of 1 NVLINK device. - The Tegra NVLINK endpoint driver programs the NVLINK controller present in the Tegra SOC. - Endpoint drivers register themselves with the NVLINK core driver. As part of the registration, the endpoint driver provides the core driver a structure of callback functions.
