01:44 <brads> bas25: I did try a test to configure gpio irq in the devicetree and whilst I seemed to be able to define the gpio irq I did not find a way to allocate it to a pin for gpiomon to use

01:51 <brads> This was the basic devicetree config I was playing around with to try to add the 8th gpio irq to pin 3 on the 40 pin header of the N2 https://pastebin.com/2ebAwPEz I also triied with gpio-keys input driver

01:52 <brads> I wonder if the driver can be enhanced to allow it to be defined at runtime by gpioset command.

02:05 <brads> The example here might be relevant I think - https://www.kernel.org/doc/Documentation/devicetree/bindings/interrupt-controller/amlogic%2Cmeson-gpio-intc.txt

02:14 <brads> On another topic im testing out PREEMPT_RT on the N2 (comming to a mainline kernel near you for arm64 soon) and I think I need to raise this with the Realtime kernel team but I will ask here first as it's related to the meson drivers. I am seeing system hang's using the mmc driver. My solution is to run the mmc via the USB adaptor / interface which seems fine. I enabled some runtime

02:14 <brads> deadlock checks and found mmc appears to be conflicting with the led heartbeat driver and causing a potential deadlock https://pastebin.com/W7VHy1V8 Does anyone have some suggestions I could try?

02:16 <brads> I was going to try to remove the idle drivers and try a full dynticks setup next

04:21 <brads> tickless setup with frequency scaling & idle cpu controls disabled seems to remove the deadlock conditon

11:16 <lucastanure> Hello all, I would like to help amlogic linux kernel. I have one vim3 board. How Can I help? I have been working with linux device drivers for the last 5 years. Anything I can work on?

16:01 <xdarklight> lucastanure: we have a support-matrix (per SoC) in the wiki: http://linux-meson.com/doku.php - if support for <you name it> is missing then feel free to add it (and to ask any questions :-)). also if an existing driver doesn't support all features that you want: same thing there

17:41 <lucastanure> great, will have a look
