Hi all, I have a question of display (forgive me if it’s too simple because I’m not familiar with display): My scenario is as below: gbm_bo_create to create gbm_bo Get its handle drmModeAddFB to specify this bo as scanout buffer do rendering to this bo by OpenCL(Beignet) drmModePageFlip to do page flip Does display engine directly read contents from scanout buffer or read contents from LLC of this scanout buffer? Environment: SKL GT2, on console mode(no X). Thanks, Chuanbo Weng |
