[gentoo-user] Tracking kernel patches

2019-05-25 Thread Adam Carter
I need to use this patch;
https://marc.info/?l=linux-block=155772952511144=2

Is there some way to track its progress toward inclusion in the stable
release?

x86 isn't the only game in town.

There's also the raptorcs OpenPOWER systems which is the only new high
performance hardware that is owner controlled, has foss firmware and no
PSP/ME DRM.

The new amd x86 are just as problematic due to having the PSP (AMD's ME)
and all the problems that come with that.

I don't include RISC-V since it is just as expensive as OpenPOWER for
much less features and performance and it currently doesn't have an IOMMU.

For laptops the only decent non-intel IOMMU having option right now is
the G505S which has an IOMMU and supports coreboot with open cpu/ram
init (note many companies sell shady "open source firmware coreboot"
systems that have an entirely blobbed hw init process) Heres to hoping
for a POWER or RISC-V+IOMMU laptop!

A libre-firmware OpenPOWER Blackbird system is less expensive than a
fully pimped libre-firmware KGPE-D16 and is many times faster even with
just the base 4 core cpu (4 threads per core :D) and has the IBM version
of OpenBMC which is better than the facebook version that was ported to
the KCMA-D8/KGPE-D16's less powerful BMC.

POWER is also the only high performance general computing CPU that is
made in usa so you support jobs that pay a living wage at a fab that
isn't messed around with by the PRC.
Raptor claims their boards are us made as well although that is a lofty
claim claim in the technology sector as the legal standard is "all or
virtually all" components and many companies get shady like a certain
one that claims their "linux focused" system is "us made" but the only
part made here is the metal case.

I would say the best and most secure setup would be:
OpenPOWER Blackbird workstation
KCMA-D8 for VM gaming (POWER only has a few indie games right now not
anything commercial) which can max out the latest games in a VM at 1080p
with a 4386 cpu and a RX590.
G505S laptop for mobile computing running qubes

Ideally you wouldn't run any programs on bare metal and everything would
be done in a VM which is what I do even for gaming, watching movies etc.

That only works if you have dmix enabled and set all audio sources to use the
dmix devices as the default audio device. If you don't have an alsa
configuration in ~/.asoundrc or /etc/asound.conf dmix should be enabled
by default, in which case it might be that one of the audio sources is
grabbing the hardware device directly instead of going through the
default device. See [1] for details.

Hm. It should. I use pulseaudio now, but when I was still using just 
ALSA alone, it would by default use dmix to play multiple sources at the 
same time.


Check if you have ALSA configuration files and delete them (or rather 
move them to a backup location)


  ~/.asoundrc
  /etc/asoundrc

If any of those files exist, delete them. Reboot to be 100% sure ALSA 
gets rid of whatever config it was using before. The default config of 
ALSA should use dmix then. I think...


If that doesn't help, see how each application is configured. If the 
audio settings of the application are set to use an ALSA hardware 
device, then yeah, it might block all other applications from using the 
sound device. Normally, you want to select the "default" ALSA device in 
each application's settings.





[gentoo-user] alsa and multiple sources of sound...

2019-05-25 Thread tuxic
Hi,

I thought, alsa could handle multiple sources of sound
simultanously...

I was playing around witht he FAUST programming language (which is
a functional programming language for DSP kind of things).
>From a input script this language compiles an executable, which
(beside other targets) speaks to alsa.

But:
For example when running blender (which connects to alsa) and 
the trying one of FAUST generated executables, the latter saus
"alsa error -16 : Device or resource busy".
For me it looks like alsa could not handle multiple sources
at the same time.

Is this dependant on a configuration "something" or is alsa
really limited that way or..?

Cheers!
