Further notes

Reading 0xe4361254 (address) in Lenovo BIOS always yields FFFFFFFF, even when writing to it (and writing to it doesn't affect brightness controls). - 'mtjm' on IRC found that the buttons (Fn keys) control /sys/class/backlight/acpi_video0 which has no affect on 61254 (BLC_PWM_CTL). He says + 'mtjm' on IRC found that the buttons (Fn keys) control /sys/class/backlight/acpi_video0 which has no affect on 61254 (BLC_PWM_CTL). This person says intel_backlight has different values and uses the register. devmem2 works, needs checking lspci -vv for where the memory is mapped, which is different than on coreboot; mtjm found that it was 0xec061254 on his system (X60 Tablet), and the register value is different too. This is relevant, because we still don't know how backlight controls are actually handled. We got it working by accident. We need to know more.. @@ -93,7 +93,7 @@

What we want to do is calculate a good value, instead of setting it in devicetree.cb. mtjm says about backlight physics: it has a light source , uses pulse width modulation (PWM) to turn it on/off, dimming is done by spending less time on. - Note: this may not be correct; he says his understanding is based on how the Lenote yeeloong works. + Note: this may not be correct; this person says that their understanding is based on how the Lenote yeeloong works.
