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.

/*
Wait for start of multiple VBLANK intervals for each thread.
This function places the thread in WAIT state until the start of the next VBLANK, after the
specified number of VSYNCs has elapsed since the last time a VBLANK wait function was called.
The sceDisplayWaitVblankStartMulti() and sceDisplayWaitVblankStartMultiCB() functions make the
respective thread wait until the next VBLANK after the specified number of VSYNCs have elapsed
as determined from the VSYNC count that was returned from the last VBLANK wait state, that was
recorded for each thread.
For example, if the sceDisplayWaitVblankStartMulti() function is called with 2 specified for
uiVcount, and no VSYNCs have elapsed since the last call, the thread will wait until the start
of the second VBLANK. If one VSYNC has elapsed since the last call, the thread will wait until
the start of the next VBLANK. If two or more VSYNCs have elapsed since the last call, the thread
will start at the next VBLANK. This enables the system to run at a fixed FPS as long as no
processing drop occurs. If the function is called with 1 specified for uiVcount, the same
operations as sceDisplayWaitVblankStart() and sceDisplayWaitVblankStartCB() will be performed.
The sceDisplayWaitVblankStartMulti() 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

/*
Wait for start of multiple VBLANK intervals for each thread.
This function places the thread in WAIT state until the start of the next VBLANK, after the
specified number of VSYNCs has elapsed since the last time a VBLANK wait function was called.
The sceDisplayWaitVblankStartMulti() and sceDisplayWaitVblankStartMultiCB() functions make the
respective thread wait until the next VBLANK after the specified number of VSYNCs have elapsed
as determined from the VSYNC count that was returned from the last VBLANK wait state, that was
recorded for each thread.
For example, if the sceDisplayWaitVblankStartMulti() function is called with 2 specified for
uiVcount, and no VSYNCs have elapsed since the last call, the thread will wait until the start
of the second VBLANK. If one VSYNC has elapsed since the last call, the thread will wait until
the start of the next VBLANK. If two or more VSYNCs have elapsed since the last call, the thread
will start at the next VBLANK. This enables the system to run at a fixed FPS as long as no
processing drop occurs. If the function is called with 1 specified for uiVcount, the same
operations as sceDisplayWaitVblankStart() and sceDisplayWaitVblankStartCB() will be performed.
The sceDisplayWaitVblankStartMulti() 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
sceDisplayWaitVblankStartMultiCB() function.
Use of the sceDisplayWaitVblankStartMulti() or sceDisplayWaitVblankStartMultiCB() function is
not recommended while a callback function is executing.
uiVcount Number of VSYNC cycles to wait for (1 to 65535)
