Proxmox iGPU Passthrough only works on Windows guests
I wanted to passthrough UHD 630 to a DSM guest. I thought that PCIe passthrough in Proxmox has matured enough that it will be a straightforward task to assign my iGPU Intel UHD 630 to a Linux guest. This was not the case. I’m getting the following errors on a Linux and Mac guests: Host…

Attempts to fix corrupted BTRFS volume in DSM
I was restarting a Docker container in my NAS’ DiskStation and I suddenly got a warning that my primary volume is mounted in read-only mode. Checking dmesg, I saw an error about corrupted leaf. At this point, I don’t have an idea how BTRFS works, and no idea what is a leaf. I spent two…

It uses Megatec Protocol which is supported by Network UPS Tool’s blazer_ser driver.

Wyze Cam Experiments
For the past couple of days I’ve been experimenting with Wyze Cam v2 and Xiaomi Xiaofang 1s. It’s an identical product that has Ingenic T20 as SoC. It’s a camera we used 3-4 years ago but stopped using because of general unreliability (microSD regularly burning out, occasional disconnection). I really did not have any goal…
