And of course the fact +that the CEC framework is in staging at the moment also prevents +this driver from being mainlined. + +Some notes: + +1) Regarding the "autonomous" mode of the Pulse-Eight: currently this +is disabled, but the idea is that this allows basic functionality +when the PC is off, and it can wake-up the PC through USB. + +To prevent the device to go into autonomous mode the driver would +have to send MSGCODE_SET_CONTROLLED 1 and then send a ping every +30 seconds (in practice once every 15 seconds would be good). When +powering off or going to standby send MSGCODE_SET_CONTROLLED 0 to +turn the autonomous mode back on. + +This needs to be implemented in the driver. Autonomous mode was +added in firmware v2. + +2) Writing to the EEPROM can only be done once every 10 seconds. + +3) To use this driver you also need to patch the inputattach utility, +this patch will be submitted once this driver is moved out of staging. + +diff -urN linuxconsoletools-1.4.9/utils/inputattach.c linuxconsoletools-1.4.9.new/utils/inputattach.c +--- linuxconsoletools-1.4.9/utils/inputattach.c 2016-01-09 16:27:02.000000000 +0100 ++++ linuxconsoletools-1.4.9.new/utils/inputattach.c 2016-03-20 11:35:31.707788967 +0100 +@@ -861,6 +861,9 @@ + { "--wacom_iv", "-wacom_iv", "Wacom protocol IV tablet", + B9600, CS8 | CRTSCTS, + SERIO_WACOM_IV, 0x00, 0x00, 0, wacom_iv_init }, ++{ "--pulse8-cec", "-pulse8-cec", "Pulse Eight HDMI CEC dongle", ++ B9600, CS8, ++ SERIO_PULSE8_CEC, 0x00, 0x00, 0, NULL }, + { NULL, NULL, NULL, 0, 0, 0, 0, 0, 0, NULL } + }; + +diff -urN linuxconsoletools-1.4.9/utils/serio-ids.h linuxconsoletools-1.4.9.new/utils/serio-ids.h +--- linuxconsoletools-1.4.9/utils/serio-ids.h 2015-04-26 18:29:42.000000000 +0200 ++++ linuxconsoletools-1.4.9.new/utils/serio-ids.h 2016-03-20 11:41:00.153558539 +0100 +@@ -131,5 +131,8 @@ + #ifndef SERIO_EASYPEN + # define SERIO_EASYPEN 0x3f + #endif ++#ifndef SERIO_PULSE8_CEC ++# define SERIO_PULSE8_CEC 0x40 ++#endif + + #endif |
