Hi Jani, During plumbers I had some discussions with Daniel about supporting OLED screens. Userspace may need to know that a panel is OLED for 2 reasons: 1) To avoid screen burn-in 2) OLED screens do not have a classic backlight, so in some cases some sort of brightness/contrast emulation through gamma tables may be necessary to still allow the user to control the brightness. The idea we've discussed is to add a property on the drm_connector (details to be filled in) which indicates that the panel is an OLED panel. This has lead to the question: "how do we know the panel is OLED"? Do you know if this info is coded into the VBT somewhere?
