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.
Plans for 2024
For this year I would like to finally get rid of all the legacy
DDE-Linux projects. I would also like to update Mesa to the current
version by using Goa. This requires Meson support in Goa, which might
become my Hack'n'Hike project 2024.
Since I use an Alder Lake laptop now, 3D acceleration and proper audio
driver support would be a nice to have for me personally. If there is
spare time, I want to have a look into audio re-sampling, since this
becomes an increasingly pressing matter.
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
