<KD0OHR> Hello all, I ask this a lot but how do I use cameras in linux on RK3399?
<KD0OHR> Maybe someone will see this today
<stdint> KD0OHR, which type of camera?
<KD0OHR> OV13850
<KD0OHR> Via mipi
<stdint> KD0OHR, the mipi camera has had the v4l2 supporting
<stdint> KD0OHR, but I am not sure about the ov13850

<KD0OHR> Someone pointed me toward https://github.com/rockchip-linux/kernel release-4.4 branch drivers/media/platform/rk-isp10/
<KD0OHR> And the userspace demp https://github.com/rockchip-linux/rk_camera
<KD0OHR> *demo
<stdint> KD0OHR, it is just for the cif

<wzyy2> That isp driver and userspace will be droped.
<wzyy2> Some guys are working on a better version for upstream. https://chromium-review.googlesource.com/c/486520/

<KD0OHR> I actually ran into a few problems, sorry I didn't see this earlier
<KD0OHR> When compiling the driver and userspace, I noticed the firefly distro is Linux firefly 4.4.16 #20 SMP PREEMPT aarch64 aarch64 aarch64 GNU/Linux, think that was supposed to be for aarch64 armhf anyway
<KD0OHR> 64 kernel, 32 userland
<KD0OHR> It seems like nothing will work :/

<ayaka> Myy, that driver could work at linux
<ayaka> actually most of the work of rockchip mpp and driver is verified under the linux
<Myy> Indeed, given the Debian packages provided :)
<Myy> I'd just like to have a quick test suite that I could without dependencies, though, in order to test the driver easily with different kernels versions.
<ayaka> Myy, I know somebody has tried to port that driver into upstream before
<Myy> Yes, it's phh
<ayaka> but he met the memory problem
<phh> well I'm not too sure if it's memory
<ayaka> Myy, there are some unit test program shipped with rockchip mpp
<Myy> Oh ! I'll take a look at that then
<ayaka> I would suggest you use that to verified driver
<ayaka> Myy, the default debian or yocto package won't install them
<Myy> I'll try to recompile them
<ayaka> Myy, which distribution do you use now?
<Myy> I'm using Ubuntu Xenial from ARMbian and Gentoo ARM without systemd.
<Myy> So I kinda test both Linux worlds
<ayaka> Myy, then there would be obj-arm* like directory when you build rockchip mpp
<ayaka> you could find it at test sub directory of it
<Myy> Ok, I'll give it a shot on Ubuntu
<Myy> Alright, recompiling a kernel on the Ubuntu board. Once done, I'll recompile the vcodec driver and launch the mpp tests

<Myy> Looks like atomic_read calls were replaced by a refcount_read calls on the new kernels
<Myy> Okay, replacing atomic_read calls by refcount_read call just freeze the whole system on module load
