Roadmap 2024

[Norman Feske]

Hi Sebastian,

thank you for the elaborate reply, which is perfectly aligned with my 
perspective. I'm especially grateful that you have taken the TCP/IP line 
of work under your wings and wholly anticipate your goal to retire the 
last traces of the legacy-DDE-Linux as soon as possible.

Speaking of audio, I forget to mention that I'm currently right in the 
middle of designing and implementing new infrastructure (session 
interfaces, mixer) for audio on Genode. I have three goals: First, to 
make audio drivers pluggable (following the tracks of our pluggible 
network/display/input drivers). Second, to make audio routing flexible 
(similar to how the NIC router gives us so much flexibility for network 
traffic). And third, to overcome the uncertainties of the current 
solution with respect to drifting/buffering/latency/jitter. To solve the 
latter, I'm applying an adaptive re-sampling approach that gives audio 
producers and consumers the freedom to use sample rates they see fit. 
Hence, the re-sampling is part of the my current work. I'm going for 
b-spline-based interpolation (in the time domain) in my first take. But 
this is of course not set in stone.

I plan to have the first version of the new infrastructure ready for 
Genode 24.02. Should it be received favorable, maybe we can jointly 
aspire converting the existing audio drivers and applications (i.e., 
vfs_oss) until version 24.05?

Cheers
Norman
