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.

This function places the thread in WAIT state until the start of the next VBLANK, after the specified number of

function as the starting point.
The sceDisplayWaitSetFrameBufMulti() and sceDisplayWaitSetFrameBufMultiCB() functions make the thread wait until
the next VBLANK after the specified number of VSYNCs have elapsed as determined from the VSYNC count that the last
frame buffer update was performed.
For example, if the sceDisplayWaitSetFrameBufMulti() function is called with 2 specified for uiVcount, and no
VSYNCs have elapsed since the last update of the frame buffer, the thread will wait until the start of the second
VBLANK. If one VSYNC has elapsed since the last update of the frame buffer, the thread will wait until the start
