| hverkuil | hi all | [11:52] |
| Feedback for this RFC patch would be appreciated: https://patchwork.linuxtv.org/patch/65318/ | [11:57] | |
| syoung | hi all | [11:58] |
| hverkuil | syoung: when testing on a Allwinner A10 cubieboard this week I noticed that the kernel log was spammed with "IR event FIFO is full!".
not sure if dev_err is the right error level for that message. or what the cause is. Otherwise no updates from me other than that I'm behind with patch review and hope to go through pending patches tomorrow or Monday. | [12:00] |
| syoung | hverkuil: that's interesting, I've never seen this message being spammed
Was the device receiving IR or did it start spamming all on its own? | [12:04] |
| hverkuil | Started right after booting it. I didn't do anything with the IR.
I can debug if you give some pointers. | [12:06] |
| syoung | hverkuil: thanks!
So this is the sunxi-cir.c driver. The driver reports IR activity from the interrupt handler, using ir_raw_event_store_with_filter(). That IR is then processed from a separate thread, which is scheduled from ir_raw_event_handle(). ir_raw_event_store_with_filter() fills a kfifo of size 512 which is read from the thread. Considering there is no IR at all, the driver should not be reporting anything, except for a superious read which can happen at startup or broken IR receives which detect sunlight as infrared signal (it should have a carrier so this does not usually happen) For some reason the sunxi-cir is calling ir_raw_event_store_with_filter() when it shouldn't, basically. This driver was originally written for the a10 and then got support added for later generations. I wouldn't be surprised if later commits broke a10. I don't have this hardware (any generation) so I haven't looked at the driver much, I'm afraid. | [12:13] |
| mchehab | hi all... sorry for being late
got sidetracked by a meeting | [12:30] |
| hverkuil | n/p | [12:30] |
| mchehab | scheduled at teh very last minute
I'm also very busy those days... I should be doing some media related work probably tomorrow... merging the atomisp patches so far to the fixes branch and handling any pending PRs | [12:30] |
| hverkuil | pinchartl: do you think the cleanup/refactor part of the ti-vpe cal series is ready to be merged? or are you waiting for reviews of v2? I'd like to get all the cleanup/refactor stuff done soonish.
syoung: hmm, I tried to revert some promising patches, but no luck. I keep getting interrupts. I guess I shouldn't get any interrupts if there is no IR activity? | [12:36] |

| pinchartl | hverkuil: in my opinion it's ready, but Tomi is on vacation this month | [13:19] |
| ..................................................... (idle for 4h24mn) | ||
| syoung | hverkuil: yes, it shouldn't be generating interrupts
what model do you have exactly? | [17:43] |
| .......... (idle for 47mn) | ||
| hverkuil | The original cubieboard with an A10 SoC (arch/arm/boot/dts/sun4i-a10-cubieboard.dts) | [18:30] |
