I have been experimenting with trying to get video acceleration working on the A83T. I can see from /proc/device-tree/soc/... that there is already a video-engine node within the current A83T device tree. It appears to be applied as one of the megous patches ARM-dts-sun8i-a83t-Add-cedrus-video-codec-support-to-A83T-untes.patch. Admittedly this is noted as being untested. In my initially created build via the build framework, Cedrus was not present at all among the list of loaded modules. I addressed this by creating an entry in the Cedrus compatibility table for the sun8i-a83t-video engine drv-sun8i-a83t-cedrus-add-variant.patch It now appears to load but complains about being unable to allocated an SRAM: [ 10.046406] cedrus 1c0e000.video-codec: Failed to claim SRAM [ 10.046490] cedrus 1c0e000.video-codec: Failed to probe hardware [ 10.091215] cedrus 1c0e000.video-codec: Failed to claim SRAM [ 10.091339] cedrus 1c0e000.video-codec: Failed to probe hardware [ 10.419296] cedrus 1c0e000.video-codec: Failed to claim SRAM [ 10.419597] cedrus 1c0e000.video-codec: Failed to probe hardware [ 20.193058] cedrus 1c0e000.video-codec: Failed to claim SRAM [ 20.193114] cedrus 1c0e000.video-codec: Failed to probe hardware [ 20.193322] platform 1c0e000.video-codec: deferred probe pending: (reason unknown) Using both sun8i-a23-a33.dtsi and sun8i-h3.dtsi as points of reference, I attempted to make an SRAM allocation under the system controller but this still appears to fail with the same failure messages. I have double checked in the user manual and VE memory should definitely exist at 0x01D0 0000. arm-dts-sun8i-a83t-add-ve-node.patch I would be grateful for any pointers. Thanks Ryzer

Hi all, I've just booted my NanoPi M4 V2 after not using it for a year or so and when I log in via ssh I'm told the / usage is at 100% - I've deleted all logs and the usual suspects but to no avail uname gives Linux M4V203 5.10.63-rockchip64 #21.08.2 SMP PREEMPT Wed Sep 8 10:57:23 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux I'm using a 32gb SD card df -h gives Filesystem Size Used Avail Use% Mounted on udev 1.9G 0 1.9G 0% /dev tmpfs 387M 41M 346M 11% /run /dev/mmcblk1p1 29G 29G 0 100% / tmpfs 1.9G 0 1.9G 0% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup tmpfs 1.9G 4.0K 1.9G 1% /tmp /dev/nvme0n1p1 458G 73M 434G 1% /mnt/Docker /dev/nvme0n1p2 458G 280G 155G 65% /mnt/music /dev/zram0 49M 20M 26M 44% /var/log tmpfs 387M 0 387M 0% /run/user/0 any ideas ?
