Hi everyone, I am trying to understand how serio works in Linux. When reading drivers/input/mouse/synaptics.c I found a special serio type: SERIO_PS_PSTHRU. I git-grep the source tree and it seems synaptics driver is the only user of the type. I cannot find any detailed docs explaining why the synaptics driver needs this, and what's the difference between this pass-through serio and psmouse->ps2dev.serio. Can anyone help me with this? Any pointer or keyword is very much appreciated. Thank you very much. jj -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
