I think you can drop lirc-0005-uinput.patch, this should be fixed upstream https://sourceforge.net/p/lirc/tickets/213/

lircd-uinput should now also work fine (https://sourceforge.net/p/lirc/tickets/211/) so I think we're now good to switch to that and drop the deprecated --uinput option of lircd.

[lrusak]

We might want this back then, lrusak@cd18f93

[Kwiboo]

@HiassofT @lrusak Thanks!, wasn't sure about the uinput patch to begin with.

I have now dropped lirc-0005-uinput.patch and added a slightly modified version of lrusak/LibreELEC.tv@cd18f93
I had to add --release=_UP to the lircd config or a pressed key would end up repeated indefinitely.

Should eventlircd drop the --release=_UP argument now that lircd generates _UP events?

[lrusak]

I'm not sure about the --release=_UP argument. It's probably worth it to do some testing and get it into a @MilhouseVH build

[Kwiboo]

Updated again: 98-eventlircd.rules modified to enable eventlircd for lircd-uinput devices

[Kwiboo]

It is probably best to leave --release=_UP on eventlircd, it does not generate an extra _UP events.

Seems to be working on NUC (Skylake, Harmony One with RC6 profile). Will include in build tonight. Please keep an eye out for issues.

Edit: Build I just tested includes:

Updated again: 98-eventlircd.rules modified to enable eventlircd for lircd-uinput devices

[Kwiboo]

@MilhouseVH thanks for including this in your build!

I have no more changes planed as everything seems to be back to "normal" after the 98-eventlircd.rules change.

[HiassofT]

I've tested Milhouse build 1231 on a RPi3 with GPIO receiver and so far everything seems to be fine!

[lrusak]

@MilhouseVH all good?

[MilhouseVH]

No problems reported so far - seems to be good.
