Hello Dave, or anyone else affected, Accepted raspberrypi-userland into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/raspberrypi- userland/0~20200520+git2fe4ca3-0ubuntu3~20.04.1 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-focal. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Description changed: [Impact] The incorrect permissions on these devices mean the regular console user cannot access various videocore services. An example of a side-effect of this is that camera usage (via the new libcamera mechanism) requires root access. Likewise, usage of the GPU (under the KMS system) for H.264 decoding (via v4l2m2m) likewise requires root access. [Test Plan] * Flash the appropriate version to a fresh SD card and boot it * sudo apt install libraspberrypi-bin # because it's not seeded on focal (this can be skipped on impish) * sudo reboot * ls -l /dev/vc* /dev/dma_heap/ * Note that /dev/vcio, /dev/vcsm-cma, /dev/vchiq, /dev/dma_heap/* have incorrect permissions (specifically, their ownership is not root:video and/or their mode is not 0664) * sudo reboot - * sudo add-apt-repository ppa:waveform/userland * sudo apt install libraspberrypi-bin * sudo reboot * ls -l /dev/vc* /dev/dma_heap/ * Note that /dev/vcio, /dev/vcsm-cma, /dev/vchiq, /dev/dma_heap/* now have correct permissions (root:video ownership, and mode 0664) [Regression Potential] Only the permission changes are being backported, not a fully updated userland. Nonetheless, existing functionality from userland should be re-tested, in particular the legacy camera stack, with the following procedure: * Attach a raspberry pi camera module to the board * Add "start_x=1" and "gpu_mem=128" to /boot/firmware/config.txt * sudo reboot * raspistill -o test.jpg * Confirm that test.jpg contains a valid picture The "tvservice" binary *may* be tested too, but is known to be inoperable under the arm64 architecture (see LP: #1944541). It is also worth noting that the test plan above only looks at the permissions as libcamera is not *currently* expected to operate on Focal. Tests should be carried out on all supported boards (Zero 2, 2B, 3B, 3A+, 3B+, 4B) under both armhf and arm64 architectures (within the caveats noted above about the arm64 architecture). [Original Description] The /dev/vcio can have the wrong permissions due to a change in the kernel. As reported in https://github.com/raspberrypi/linux/pull/4624 (which I missed entirely, sorry pelwell!) we'll need a change in the udev rules to ensure the correct permissions are set. ** Changed in: raspberrypi-userland (Ubuntu Focal) Status: New => Fix Committed ** Tags added: verification-needed verification-needed-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958563 Title: [SRU] Wrong permissions on vcio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/raspberrypi-userland/+bug/1958563/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
