Correct, as the vpu is still in charge of composition.
We have the basics working for dpi displays, but it's still missing hdmi and some configuration around pixel valve assignment.I don't think kms mode is bug free yet on Pi4's.
I'm not sure I'd claim they were close, but have vaguely similar uses.Dispmanx is very close to EGL
Whoops noobie mistake, kernel is not OS.There isn't a 64bit Raspbian, only a 64bit kernel that you can run underneath the 32bit userspace.
So is EGL used in VC6 OpenGL or dispmanx used instead?Dispmanx is very close to EGL
I'm not sure I'd claim they were close, but have vaguely similar uses.
https://www.khronos.org/egl/So is EGL used in VC6 OpenGL or dispmanx used instead?
Those layers confuse me.
Hard to believe someone understands that V3D drm code, not sure where EGL fits in that lot.
But if dispmanx is being used for compositing were is that happening?
In drm/vc4? Still clueless
For Pi4 the "underlying native platform window system" is either OpenGL, or DRM/KMS.EGL™ is an interface between Khronos rendering APIs such as OpenGL ES or OpenVG and the underlying native platform window system.
