I'm working on kernel for rx1950 in parallel with userspace work. Since next step is improved battery driver, I've spent couple of hours to create following app . It's simple battery monitor with logging capability - I need some logs to get U,I(t) battery dependencies, as I don't believe windows driver, it seems that it displays battery level applying some heuristic - I don't see direct correlation between battery voltage/current and level displayed by windows driver. P.S. I've sent rx1950 patches upstream on 20 of March and still no responce. I'm a bit disappointed - does it really take so long to review patch series?
