Hi Mauro, Since v4.12 we set the LIRC_CAN_GET_REC_RESOLUTION lirc feature, and as a result lircd uses the ioctl LIRC_GET_REC_RESOLUTION. That ioctl has always been broken in rc-core. I should have tested lirc decoding, I'll add it to my rc checklist. Sorry. Thanks, Sean The following changes since commit 2748e76ddb2967c4030171342ebdd3faa6a5e8e8: media: staging: cxd2099: Activate cxd2099 buffer mode (2017-06-26 08:19:13 -0300) are available in the git repository at: git://linuxtv.org/syoung/media_tree.git for-v4.13d for you to fetch changes up to 5b96f8172791fbc8f511ea453b8828fe6f02f03c: [media] lirc: LIRC_GET_REC_RESOLUTION should return microseconds (2017-07-11 10:38:18 +0100) ---------------------------------------------------------------- Sean Young (1): [media] lirc: LIRC_GET_REC_RESOLUTION should return microseconds drivers/media/rc/ir-lirc-codec.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
