(after I turn on the lamp, but it persists even after I turn it off and cover the IR sensor). That's weird, because on H6 in CIR_RXSTA, bit 5 is undefined but corresponding bit in CIR_RXINT is DRQ_EN (RX FIFO DMA Enable) So I'm not sure what it could be flooded with and why IRQs keep being fired, even with no sensor input after the FIFO is read. regards, o. > If it's confirmed, maybe

Sometimes it locks up too (but not frequently). Storage locks up always (any program that was not run before the crash can't be started and lock up the kernel hard, programs that were executed prior, can be run again). Exactly the same kernel build on H5 seems to work (or at least I was not able to trigger the crash). So this seems to be limited to H6 for now. I suspect that the crash occurs sooner if I vary the light (turn on/off the table lamp light). Without your patches, everything works fine on H6, and I never see crashes/lockups. I tired physically covering the IR receiver, and that helps preventing the crash. As soon as I uncover it, the crash happens again in 1s or so: rcu: INFO: rcu_sched detected stalls on CPUs/tasks: rcu:0-: (1 GPs behind) idle=4ea/0/0x3 softirq=4483/4484 fqs=2444 rcu: INFO: rcu_sched detected stalls on CPUs/tasks: rcu:0-: (1 GPs behind) idle=4ea/0/0x3 softirq=4483/4484 fqs=9777 This time I got the hung task and reboot: (probably not directly related) INFO: task find:560 blocked for more than 120 seconds.

Do you have any log? I tested with my kernel (https://megous.com/git/linux/log/?h=opi3-5.2). I also tried with 5.1 and the same kernel build on H5, to exclude some early 5.2-rc bugs and to see if this is H6 specific. I'll try testing again with your patches, and get you some logs. But last time they were not very informative. regards, o. > Thanks, > Clément > > > > > Enabling/disabling ir node was enough to trigger/stop the RCU stalls on H6. > > > > regards, > > o. > > > > > Regards, > > > Clément > > > > > > [1] https://lore.kernel.org/patchwork/patch/1031390/#1221464 > > > > > > Changes since v1: > > > - Document reset lines as required since A31 > > > - Explain the memory mapping difference in commit log > > > - Fix misspelling "Allwiner" to "Allwinner" > > > > > > Clément Péron (8): > > > dt-bindings: media: sunxi-ir: add A31 compatible > > > media: rc: sunxi: Add A31 compatible > > > ARM: dts: sunxi: prefer A31 instead of A13 for ir > > > dt-bindings: media: sunxi-ir: Add A64 compatible > > > dt-bindings: media: sunxi-ir: Add H6 compatible > > > arm64: dts: allwinner: h6: Add IR receiver node > > > arm64: dts: allwinner: h6: Enable IR on H6 boards > > > arm64: defconfig: enable IR SUNXI option > > > > > > Igors Makejevs (1): > > > arm64: dts: allwinner: a64: Add IR node > > > > > > Jernej Skrabec (1): > > > arm64: dts: allwinner: a64: Enable IR on Orange Pi Win > > > > > > .../devicetree/bindings/media/sunxi-ir.txt| 11 +-- > > > arch/arm/boot/dts/sun6i-a31.dtsi | 2 +- > > > arch/arm/boot/dts/sun8i-a83t.dtsi | 2 +- > > > arch/arm/boot/dts/sun9i-a80.dtsi | 2 +- > > > arch/arm/boot/dts/sunxi-h3-h5.dtsi| 2 +- > > > .../dts/allwinner/sun50i-a64-orangepi-win.dts | 4 > > > arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi | 18 ++ > > > .../dts/allwinner/sun50i-h6-beelink-gs1.dts | 4 > > > .../dts/allwinner/sun50i-h6-orangepi.dtsi | 4 > > > .../boot/dts/allwinner/sun50i-h6-pine-h64.dts | 4 > > > arch/arm64/boot/dts/allwinner/sun50i-h6.dtsi | 19 +++ > > > arch/arm64/configs/defconfig | 1 + > > > drivers/media/rc/sunxi-cir.c | 1 + > > > 13 files changed, 68 insertions(+), 6 deletions(-) > > > > > > -- > > > 2.20.1 > > > > > > > > > ___ > > > linux-arm-kernel mailing list > > > linux-arm-ker...@lists.infradead.org > > > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel > > ___ > linux-arm-kernel mailing list > linux-arm-ker...@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel

Does H6 support actually work? I don't see any driver changes and last time I tried with the exact same bindings, I got RCU stalls shortly after boot.

[PATCH v2 00/10] Allwinner A64/H6 IR support
Hi, A64 IR support series[1] pointed out that an A31 bindings should be introduced. This series introduce the A31 compatible bindings, then switch it on the already existing board. Finally introduce A64 and H6 support.
