Summary0001801: Enable more HDMI logcat messages.
DescriptionSKB want to see more HDMI logcat messages for debugging VoC issue.

Please apply following items.

#1
Set the persist.log.tag.HDMI property as DEBUG.
It should be set without reset the device, so you may need to add it to init.rc script.
Of course, if you have better idea to apply it, please apply yours.
BFX-UA300:/ # getprop | grep -i hdmi
[persist.log.tag.HDMI]: [DEBUG]

#2

Hello, Jason,

Some TV send specific cec message repeatedly.
For example, LG TV send <Device Vendor Id> repeatedly.
08-24 11:08:46.440 699 - D HDMI [R]:<Device Vendor Id> 0F:87:00:E0:91
08-24 11:09:01.071 699 - D HDMI [R]:<Device Vendor Id> 0F:87:00:E0:91
08-24 11:09:01.180 699 - D HDMI [R]:<Device Vendor Id> 0F:87:00:E0:91
08-24 11:09:01.400 699 - D HDMI [R]:<Device Vendor Id> 0F:87:00:E0:91
08-24 11:09:01.511 699 - D HDMI [R]:<Device Vendor Id> 0F:87:00:E0:91
08-24 11:09:16.250 699 - D HDMI [R]:<Device Vendor Id> 0F:87:00:E0:91
08-24 11:09:46.831 699 - D HDMI [R]:<Device Vendor Id> 0F:87:00:E0:91

So, I don't want to print this kind of messages.
I'm checking the TVs I have and I will let you know the cec messages which should not be printed.

Thank you.
Sangmin Choi.
