Release highlights since 415.27:
* Added initial support for G-SYNC Compatible monitors. See the README for details. * Added support for the following GPUs: * GeForce RTX 2070 with Max-Q Design * GeForce RTX 2080 with Max-Q Design * Added support for stereo presentation in Vulkan. * Fixed a bug that could cause OpenGL applications to crash after repeated VT-switches. * Fixed a bug that could sometimes prevent PRIME displays from being selected in the display settings page of nvidia-settings. * NVIDIA Video Codec SDK 9.0 A new release of the Video Codec SDK will be available in Q1 2019. For more information and early access sign-up, refer to https://developer.nvidia.com/nvidia-video-codec-sdk The main features available in this release are listed below: o Support for Turing NVENC/NVDEC. o The NVDECODE API (also known as the NVCUVID API) has been updated to support YUV 4:4:4 decoding for HEVC on Turing GPUs. o NvEncodeAPI has been updated to support HEVC B-frames on Turing GPUs. o NvEncodeAPI adds the capability to output the encoded bitstream, and motion vectors from motion estimation-only mode, to video memory. This avoids the overhead of copying the output from system to video memory for processing pipelines operating directly on video memory. o NvEncodeAPI now accepts CUarrays as input buffers. The SDK contains a sample application to demonstrate how to feed a Vulkan image to NVENC using the Vulkan-CUDA interop. * Added NVIDIA optical flow support. A new library libnvidia-opticalflow.so is included in the driver package. The NVIDIA optical flow library can be used for hardware-accelerated computation of optical flow vectors and stereo disparity values. The API header files, sample applications and documentation will be available in a separate Optical Flow SDK package in Q1 2019. For more information and early access sign-up, refer to https://developer.nvidia.com/opticalflow-sdk * Removed libnvidia-wfb.so from the driver package. This module was only used on X servers that did not provide their own implementation of libwfb, and all X.Org xserver versions now supported by the driver do so. * Updated the VDPAU driver to reject decoding to YUV 4:2:2 video surfaces. The NVIDIA VDPAU driver always produces YUV 4:2:0 content. Previously, the VDPAU driver implicitly converted a YUV 4:2:2 video surface to YUV 4:2:0 during decode. Now, the VDPAU driver will fail the decode request. * Optimized nvidia-installer to only run depmod(1) once when installing, rather than twice (once during the uninstall phase and again when installing new kernel modules). * Removed the NVreg_UseThreadedInterrupts kernel module parameter from nvidia.ko. This removes the ability to forcibly fall back to an older mechanism (tasklets) for running the bottom-half interrupt handler. Instead, threaded IRQs (the default since 367.44) are always used. * Added support for the following GPU: * Tesla V100-SXM3-32GB-H * Fixed a bug where destroying a direct-to-display swapchain could crash Vulkan applications. * Fixed a bug that prevented Vulkan applications from using the VK_EXT_display_control extension on a display that is driven by X. * Improved nvidia-bug-report.sh to grab the output of the `vulkaninfo` command when it is available. * Fixed build failures which resulted in errors like "implicit declaration of function drm_...", when building the NVIDIA DRM kernel module for Linux kernel 5.0 release candidates. * Fixed a bug that could prevent nvidia-xconfig from disabling the X Composite extension on version 1.20 of the X.org X server. * Fixed a build failure, "too many arguments to function 'get_user_pages'", when building the NVIDIA kernel module for Linux kernel v4.4.168. * Fixed a build failure, "implicit declaration of function do_gettimeofday", when building the NVIDIA kernel module for Linux kernel 5.0 release candidates.
