I'm using the IMX.6 custom board with the following combination Linux - Mainline 5.15 GPU driver - Etnaviv X Driver - xf86-video-modesetting OpenGL - OpenGL ES-CM 1.1 Mesa 23.3.3
When the screen is set to normal mode, the glmark2 performance score is 80. When the screen rotates to 90/270/180, the glmark2 performance score drops to 19. Is this a known issue in the modesetting driver? Or Etnaviv kernel driver? Why does performance drop after screen rotation? I have also tried with xf86-video-armada driver, I get the blank screen after screen rotation. Any help is appreciated. Thank, Vishnu
