Problem I see is that "stdcall user_alloc" gives us virtual memory that is already mapped to physical memory. (And didn't find yet how/where it is mapped.) Doesn't user_alloc allocates memory lazily, i.e. only virtual pages immediately, physical pages in PF handler? If this is the case, t...

After reading this post I managed to get two adjacent virtual pages mapped to the same physical page, RW accessible from the application: stdcall user_alloc, 0x2000 <-lin call alloc_page <-phys stdcall map_page, lin, phys, PG_UWR stdcall map_page, lin+0x1000, phys, PG_UWR May be it makes sense to c...

Hello fellow kernel-developers,

Does anyone know the steps required to implement ring-buffers for the application level?
I studied the kernel code a bit, but am afraid I don't quite understood the inner working of user heap.

Improved minimp3 from https://github.com/lieff/minimp3.

I built it into a KolibriOS native COFF library without any external dependencies.
Code and binary for Kolibrios attached.

KPACKED obj with only MP3 support and SSE2 disabled ~13b.

Where is the setting to use small font? :)
Also, what are "text fileds"?

Hello and welcome, Almost any high-level language can be used to write programs for KolibriOS, some information here: http://diamond.kolibrios.org/hll/hll_eng.htm It can be a step-stone to learn the KolibriOS API before learning a new language :) (Official API is here http://websvn.kolibrios.org/fil...

I have only AR8171(QCA8171) and AR8131 for which no datasheets are to be found, maybe you are more lucky!

Atheros/Qualcomm does not publish datasheets for these chips unfortunately. Only way is to study the code of existing open source drivers. As an example for KolibriOS, here is a driver derived mostly from open source 'alx' driver http://websvn.kolibrios.org/filedetails.php?repname=Kolibri+OS&pat...

It is possible to add support in new AR81XX driver, but I don't have the hardware to test it...

Hmm, driver called ar81xx but seems it doesnt work with my AR8131 ((

Nope, sorry, it's more or less port of the linux alx driver, only AR8161/8162/8171/8172

EDIT: I will add AR8131 support too, I found a device which has this chip :)

Have you tried plugging in the mouse after kolibri has booted?
Sometimes there is an issue with the USB hand-over from the firmware (UEFI/BIOS)
