Comment 0 for bug 1854485

[Impact]
These releases provide both bug fixes and new features, and we would like to
make sure all of our users have access to these improvements.

See the changelog entry below for a full list of changes and bugs.

[Test Case]
The following development and SRU process was followed:
https://wiki.ubuntu.com/NVidiaUpdates

Certification test suite must pass on a range of hardware:
https://git.launchpad.net/plainbox-provider-sru/tree/units/sru.pxu

The QA team that executed the tests will be in charge of attaching the artifacts and console output of the appropriate run to the bug. nVidia maintainers team members will not mark ‘verification-done’ until this has happened.

[Regression Potential]
In order to mitigate the regression potential, the results of the
aforementioned system level tests are attached to this bug.

440.36:
  * New upstream release:
    - Added support for the following GPUs:
      o GeForce GTX 1650 SUPER
      o GeForce GTX 1660 SUPER
    - Fixed graphical corruption that can occur when using glslang
      SPIR-V Generator Version <= 2.
    - Fixed a bug that could cause the X server to crash when running
      applications using GLX indirect rendering.
    - Updated the Module.symvers sanity check, which is part of the
      NVIDIA kernel module build process, to accommodate the recent
      addition of a new field in the Module.symvers file format.
      This fixes the error "The Module.symvers file is missing [...]"
      seen during driver installation or DKMS rebuilds with Linux 5.4 RC
      kernels.
    - Fixed kernel module build problems with Linux kernel 5.4.0 release
      candidates.
    - Updated nvidia-bug-report.sh to collect information about X server
      crashes from coredumpctl, when available.
    - Updated the nvidia-drm kernel module for compatibility with the
      removal of the DRIVER_PRIME flag in recent Linux kernel versions.
    - Enabled parallel GLSL shader linking by default; i.e., allow
      GL_ARB_parallel_shader_compile to work without first calling
      glMaxShaderCompilerThreadsARB().
    - Added support for HDMI 2.1 variable refresh rate (VRR) G-SYNC
      Compatible monitors on supported GPUs.For more details, see
      "Configuring Multiple Display Devices on One X Screen" in the README.
      Added support for the GLX_NV_multigpu_context and GL_NV_gpu_multicast
      extensions.For more details, see the "Configuring SLI and Multi-GPU
      FrameRendering" chapter of the README, and the extension specifications:
      https://www.khronos.org/registry/OpenGL/extensions/NV/GLX_NV_multigpu_context.txt
      https://www.khronos.org/registry/OpenGL/extensions/NV/NV_gpu_multicast.txt
    - Fixed a bug that prevented Vulkan applications running on systems
      configured for SLI. Vulkan applications can now run while SLI is enabled;
      however, they will only be able to use a single GPU.
    - Simplified the nvidia-sleep.sh sample script to no longer depend on
      unreliable detection of the current VT through X server logs.
    - Added EGL support for PRIME render offload. Please see the PRIME Render
      Offload chapter in the README for configuration details.
    - Fixed a regression introduced in 435.19.02 that would cause some applications
      which use the VK_KHR_DISPLAY extension to result in a segmentation fault.
    - Enabled HardDPMS by default. See the README entry on the X configuration
      option "HardDPMS" for more information.
    - Fixed a bug which caused corruption in the following DXVK titles:
      Saints Row IV
      Saints Row: The Third
    - Added VP9 decode support to the NVIDIA VDPAU driver. See the VDPAU Support
      appendix in the README for supported VP9 decoder profiles.
    - Fixed a bug that could cause heapUsage values reported by
      VK_EXT_memory_budget to not immediately update after vkFreeMemory was
      called.
    - Changed GPU clock management strategy to more quickly ramp down clocks
      after a drop in GPU utilization.
    - Added X configuration option, "SidebandSocketPath", which controls the
      directory in which the X driver will create a pathname UNIX domain socket
      used to communicate with the NVIDIA OpenGL, Vulkan and VDPAU driver
      components.
    - The X driver will now create a fallback pathname UNIX domain socket in
      the directory specified by the "SidebandSocketPath" option, or /var/run
      by default, which will be used by other NVIDIA driver components if they
      are unable to connect to the default abstract socket.This fixes a bug
      where graphics applications run within a network namespace (which prevents
      the use of abstract sockets) were unable to take advantage of some driver
      features, such as G-Sync.
    - Fall back to system memory when video memory is full for some
      driver-internal allocations. This can help fix Xid 13 and Xid 31 cases in
      Vulkan applications when video memory is full.
    - Fixed a bug that could cause a blank screen on some DisplayPort monitors
      when logging in to GNOME, if the nvidia-drm kernel module parameter
      modeset=1 is specified.
    - Fixed a bug that prevented NVIDIA GPUs from entering the low-power D3
      state when entering suspend-to-idle (s2idle). Note that on some systems
      this may expose an existing timing issue in the Linux kernel; see the
      "Known Issues and Workarounds" section of the "Configuring Power
      Management Support" chapter of the README for more details.

340.107-0ubuntu8
  * debian/templates/dkms_nvidia.conf.in,
    debian/dkms_nvidia/patches/buildfix_kernel_5.4.patch:
    - Add support for Linux 5.4 (LP: #1850824).
