A cmd_queue is a contiguous array of SceOledCmd of different sizes. To get the next SceOledCmd of a queue, do: 

struct SceOledCmd *cur_cmd = ...
struct SceOledCmd *next_cmd = &(cur_cmd->buf) + cur_cmd->size;

if (next_cmd->cmd == 0 || next_cmd->cmd == 255) {...} // End of queue

ksceOledWaitReady

Version NID
3.60 0x0CC6BCB4 
int ksceOledWaitReady();

Waits until the OLED has been initialized.

ksceOledGetBrightness

Version NID
3.60 0x43EF811A 
int ksceOledGetBrightness();

Get the wide brightness value (0-65536).

ksceOledSetBrightness

Version NID
3.60 0xF9624C47 
int ksceOledSetBrightness(unsigned int brightness);

Set the brightness (brightness needs to be in the range 0-65536). 0 means screen turned off, 1 means screen dimmed (like if you wait for a long time without touching your screen).

The brightness has actually 17 different values: 1 special value for brightness=0, and 16 different values for the rest (real_value=brightness/4096).

ksceOledForDriver_2F0C4B67

Version NID
3.60 0x2F0C4B67 
int ksceOledForDriver_2F0C4B67(u8 cmd, void *buffer, int size);

Sends a command to the OLED?

ksceOledForDriver_E30604CC

Version NID
3.60 0xE30604CC

Dispatches the OLED cmd list (using ksceOledForDriver_2F0C4B67).
