[Kernel-packages] [Bug 1850876] Re: CONFIG_DRM_V3D is disabled for linux-raspi2 of eoan

2019-11-24 Thread Ian Pitt
Thanks for the new kernel.  I booted it and noted that the right drivers
were now being used ( Accelerated video and glxinfo showing it was using
VC4 rather than the original llvmpipe.   However:

1) On Mate, the Pi locked up within a few seconds of resizing windows
2) On Ubuntu,  it took a few minutes but again the machine locked up after 
using applications. 

Ahead of failures, areas of the screens were flashing/jittering.   Once
locked, only a reboot would gain control of the console.

4GB Pi 4, all 64bit kernels - rock solid without acceleration on the
former kernel,  rock solid WITH acceleration when using Gentoo.

I reverted to the older kernel and the machine is back to being stable,
albeit with out the acceleration.

Title:
  CONFIG_DRM_V3D is disabled for linux-raspi2 of eoan

Status in linux-raspi2 package in Ubuntu:
  Confirmed
Status in linux-raspi2 source package in Eoan:
  Fix Committed

Bug description:
  We enabled DRM_VC4 in the linux-raspi2 of eoan, but disabled the
  DRM_V3D.

  In fact the DRM_V3D is crucial for graphical applications (such as
  ubuntu-desktop :) as it removes the graphical overhead from the cpu to
  the gpu, making the applications work much faster.

  Please refer to https://bugs.launchpad.net/ubuntu/+source/linux-
  raspi2/+bug/1848703/comments/32

  
  [Impact]
  Users reported that we should enable the DRM_V3D, then the GPU will
  be fully used when running "ubuntu-desktop"

  [Fix]
  Enable the DRM_V3D, the v3d.ko will be built

  [Test Case]
  Users already tested it, it worked well.
  
https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1848703/comments/36

  [Regression Risk]
  Low, I already did building test for arm64 and armhf, all passed.
  And uers already tested the kernel module, it worked as expected.

Yes, the Gentoo image is running 4.19.67.

Thanks,  I can wait for a more stable version.

@Hui,  I tried the patched kernel you released and posted on
https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1852035 .
It works fine ( other than the dmesg logs that the other tester posted )
under KDE Plasma and LXQt. It seems that only Mate suffers the
flickering and other rendering artifacts.   All desktops have
accelerated compositing now as expected.
