Oh, I thought reverting just this commit was not enough for you, based on the previous discussion in the patch thread. If this is enough, and the DPCD backlight by default works for you, I might be inclined to go with just defaulting to false here.

Yeah, that was indeed my experience, but I cannot reproduce that behaviour now; disabling DBC seems to be enough to make things work. It might be that I made some mistake in my earlier testing. I retested now, with the following results: Both DPCD & DBC enabled: black screen DBC enabled, DPCD disabled: works DBC disabled, DPCD enabled: works DBC disabled, DPCD disabled: works Based on my understanding of the code, DPCD backlight is required for DBC to work, so it makes sense that disabling either of the two makes things work (hence I don't understand how I got my earlier result where just disabling DBC wasn't enough). Anyhow, I'm fine with just changing the default to false.

I need to NAK my own revert. It turns out that while booting with only i915.enable_dbc=0 gives backlight, the backlight will only work until a suspend/resume cycle has taken place; after that the display will come up blank, unless i915.enable_dpcd_backlight=0 is also passed. So I'll submit a new revert.
