Subject: [PATCH] kms/crtc: Determine gamma support given the gamma length
|
||||
|
||||
The property doesn't necessarily exist when using drivers that doesn't
|
||||
support atomic mode setting, and the way it worked will break night
|
||||
light and other gamma related features. This makes things use the gamma
|
||||
length; if it is higher than 0, it definitely supports it one way or the
|
||||
other, i.e. GAMMA_LUT with the atomic backend, and drmModeCrtcSetGamma()
|
||||
with the legacy/simple backend.
|
||||
|
||||

|
||||
