SceDisplay

This module handles management of the framebuffers. It uses various display drivers (OLED, HDMI, LCD) as well as drivers to control DMA and other low level details. Embedded in this module is also the boot logo (the PS logo seen on boot) which is gzipped. On module_start, after setting up the drivers, it gunzips the logo into the SceCamera SRAM (which is unused at this time since camera is not enabled yet). Then it sets the framebuffer to the camera SRAM and turns the brightness up in incremental levels.

Thread wait for start of VBLANK interval.
This function places the thread in WAIT state until the start of the next VBLANK interval.
Regardless of whether a VBLANK interval was in progress when the sceDisplayWaitVblankStart() or sceDisplayWaitVblankStartCB() function was called, the thread enters WAIT state until the start of the next VBLANK interval.
The sceDisplayWaitVblankStart() function does not execute a thread manager callback during a WAIT state. If you also want to perform callback processing during the WAIT state, use the sceDisplayWaitVblankStartCB() function.
