* DRM: tegra_udrm: Don't set DRM_AUTH flagYogish Kulkarni2019-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | After login to Ubuntu Wayland desktop, if user tries to launch application which opens DRM device and calls e.g drmGetVersion it fails as drmGetVersion call handling in UMD will create drm_nvdc context and starts a thread to listen for close, set/drop master notifications from driver. It uses tegra_udrm_close_notify_ioctl and tegra_udrm_drop_master_notify_ioctl to register for notifications from KMD. So if DRM_AUTH is set for those ioctls they might fail if there is existing master, so don't set DRM_AUTH on those ioctls. None of the tegra_udrm ioctls are modifying KMS state so DRM_AUTH is not required anyway.

* DRM: tegra_udrm: Register DRM render nodeYogish Kulkarni2019-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | EGL searches renderDXXX device nodes in "/dev/dri/". On each node found it calls drmGetVersion() to check if version name is tegra-udrm. If name matches, it calculates primary index X corresponding to XXX. Primary index is used to create device file name "/dev/dri/cardX". When application calls eglQueryDeviceStringEXT() with <name> set to EGL_DRM_DEVICE_FILE_EXT, EGL returns the created device file name. EGL when searching for the correct DRM device, only look at render nodes, to avoid tripping on DRM mastership.

* DRM: tegra_udrm: Add tegra_udrm DRM driveryogishk2019-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Driver's init will fail unless it is inserted with modeset=1. This driver can't be used with libdrm as UMD. It also doesn't support ioctl() on driver fd Bug 200473544 Bug 2158091 Change-Id: I2b463a61a968621f7ec18d788e19c218c5091f06 Signed-off-by: Yogish Kulkarni <yogishk@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1954618 (cherry picked from commit 2f14a005053b32790f6fbccaa91c5a0baec4fc4d) Reviewed-on: https://git-master.nvidia.com/r/1956232 GVS: Gerrit_Virtual_Submit Reviewed-by: Bibek Basu <bbasu@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
