What's New

NVIDIA GPUs on Linux

• Text and icons are no longer drawn as noise with gfxstream: crosvm has KVM
  honor the guest's PAT on Intel CPUs, and NVIDIA's driver always gets cached
  host memory for uploads.
• Venus mode works on NVIDIA's proprietary driver, but stay on gfxstream_guest_angle for now:
  • SurfaceFlinger gets its buffers.
  • The console is no longer blank.
  • Apps that map video memory no longer fault the GPU.
• Ika with an nVidia GPU no longer dies at the first redraw after the GPU
  suspended while idle.

Startup Options

• "GPU Hardware" at the top picks the host GPU Ika uses; Ika then renders on
  it alone.
• CPU-rendered GPU modes are shown in yellow to alert users.
• Dropped yad dependency.

Windows (WSL2)

• Performance and compatibility improvemenmts
• 3DMark no longer fails to start once the shader cache passes 1 GB.
• gfxstream's two recording threads no longer wait for each other on every
  draw.
• The console takes two fewer trips per frame: gfxstream reads frames straight
  into crosvm's framebuffer, and the console hands them to the compositor
  without going through OpenGL.
• A render pass on one slice of a 3D render target no longer removes the D3D12
  device.
• The installer no longer warns about the devices' ACL entries.

Other

• vCPU frequency tables include the host's boost frequencies, so crosvm does
  not panic on boot.
• ARM64 hosts get a usable vCPU frequency table whatever cpufreq reports.
