=== Display problems
|
||
|
|
|
||
|
|
The video drivers from the vendor do not support being used with the classic
|
||
|
|
framebuffer.
|
||
|
|
|
||
|
|
Only DRM (Direct Rendering Manager) is supported.
|
||
|
|
|
||
|
|
A workaround, for the time being, is to use `simplefb`. Though when the device
|
||
|
|
boots in the default system, the `simplefb` framebuffer stops working. It is
|
||
|
|
suspected that it is the video drivers switching the display to HDR that are
|
||
|
|
causing this issue.
|
||
|
|
|
||
|
|
A workaround to help with this workaround has been implemented. When booted in
|
||
|
|
the default system, the early init will reboot to recovery. In recovery mode
|
||
|
|
the kernel does not exhibit this issue.
|
||
|
|
|
||
|
|
The solution to this problem will be to properly support DRM-only workflows.
|
||
|
|
|
||
|
|
Another avenue for solving this is to fix the fbdev emulation driver for the
|
||
|
|
Qualcomm vendor tree.
|
||
|
|
|
||
|
|
Yet another is to explore using mainline. Though it is unknown if the
|
||
|
|
dual-DSI display, for which the vendor driver is unique, would work well with
|
||
|
|
the generic code working with other SDM845 devices.
