Is there a plan to upgrade the kernel to 5.x? #14

I noticed that they have already add support for rg350/rg350m in kernel 5.9.

ROM & Toolchain are here:

It sounds good, but more tests should be done before the kernel upgrade, I think.

In my opinion, userland app, foundation library and modern toolchain is more important than the kernel to a retro game devices.

When the userland comes stable, at least, I, myself, will try to upgrade the kernel. Just like my working laptop, using kernel 5.x.

Thanks for your reply!

According to their description, due to the new kernel and GPU driver, IO performance is significantly improved, and the GPU is faster in most areas.

I just tried the new kernel and firmware, and found that the MTP mode was added(just like on Android).

There are still a few issues with the new kernel. For example, the old kernel has an OpenDingux-specific linkdev kernel driver that merges the left and right joystick devices into one device, and handles switching between controller and keyboard mode (X-OD-NeedsJoystick=true). For the new kernel, Paul instead decided to implement controller handling in userland in SDL2 but that's not done yet.

Here we can work on userland and upstream it to OpenDingux bit-by-bit. This is what I've been doing so far.

Once the upstream OpenDingux is fully functional, we can switch to it.

Haven't looked at OpenDingux for a few months, trying the update now from http://od.abstraction.se/opendingux/latest/gcw0-update-2020-10-08.opk
