From 9ca8dbcc65cfc63d6f5ef3312a33184e1d726e00 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Tue, 4 Aug 2015 12:17:53 -0700 Subject: Add the rt linux 4.1.3-rt3 as base Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior We lose all the git history this way and it's not good. We should apply another opnfv project repo in future.

Both ir-kbd-i2c and lirc_zilog provide support for RX events for +the chips supported by lirc_zilog. Before moving lirc_zilog out of staging: + +a. ir-kbd-i2c needs a module parameter added to allow the user to tell + ir-kbd-i2c to ignore Z8 IR units. + +b. lirc_zilog should provide Rx key presses to the rc core like ir-kbd-i2c + does. + + +2. lirc_zilog module ref-counting need examination. It has not been +verified that cdev and lirc_dev will take the proper module references on +lirc_zilog to prevent removal of lirc_zilog when the /dev/lircN device node +is open. + +(The good news is ref-counting of lirc_zilog internal structures appears to be +complete. Testing has shown the cx18 module can be unloaded out from under +irw + lircd + lirc_dev, with the /dev/lirc0 device node open, with no adverse +effects. The cx18 module could then be reloaded and irw properly began +receiving button presses again and ir_send worked without error.) + + +3. Bridge drivers, if able, should provide a chip reset() callback +to lirc_zilog via struct IR_i2c_init_data. cx18 and ivtv already have routines +to perform Z8 chip resets via GPIO manipulations. This would allow lirc_zilog +to bring the chip back to normal when it hangs, in the same places the +original lirc_pvr150 driver code does. This is not strictly needed, so it +is not required to move lirc_zilog out of staging. + +Note: Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed +and installed on Hauppauge products.
