Flags (passed to sceSysconCmdExecForDriver, etc), also lower bits of status:

Flags	Meaning
0x1	Some kind of priority that helps to select to which packet list the packet is inserted into.
0x100	Do not insert packet checksum (at tx_buf[2 + len]), where len = tx_buf[2]. And don't memset the rest of the buffer to -1 (memset(tx_buf + len + 3, -1, 29 - len)) if len < 29.
0x400	When set, use rx_extra to receive the data. rx_extra_size must be greater than 32.
0x800	When set: use tx_extra instead of tx for sending data. The size is contained in tx_extra[2] and must be smaller or equal to 253. When cleared: use tx and the size is contained in tx[2], which has to be smaller or equal 29.

Returns the timestamp of latest installed Syscon FW patch, formatted as YYYYMMDDhhmm. This comes from a string stored in Syscon FW under another format: $Date:: YYYY-MM-DD hh:mm:ss +0900#$

Example: $Date:: 2013-12-13 15:52:05 +0900#$ in Syscon FW becomes 201312131552 in Syscon command 2.

Version	NID
0.940-3.60	0x8A95D35C

Temp name was sceSysconResetDeviceForDriver.

int sceSysconSetPowerModeForDriver(int type, int mode);

It issues SMC #0 with r12 = 0x11A.

The mode argument is usually set to 0x2 or sometimes 0x8002 (which seems to correspond to some request by the UDC and BT drivers).

The type argument determines what to do.

Real define names are like: "SCE_SYSCON_POWERMODE_MODE_STANDBY".

0	Power off	{0xC0, 0, 5, type, (~mode) & 0xFF, (~mode >> 8) & 0xFF, (mode >> 16) & 0xFF}
1	Suspend (low-power state)	{0xC0, 0, 5, type, (~mode) & 0xFF, (~mode >> 8) & 0xFF, (mode >> 16) & 0xFF}
