Package: kmod
Version: 6-1.1
Severity: normal
Dear Maintainer,
I have
merkaba:~> cat /etc/modprobe.d/snd-hda-intel.conf
# c`t kompakt Linux 1/2012
# Thorsten Leemhuis, Notebooks unter Linux, S. 38ff
# S. 42, Kasten Handoptimiert
options snd_hda_intel power_save_controller=Y power_save=1
I did:
- update-initramfs -k all -u
- reboot
Yet I get:
merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save
0
Echoing the value to the corresponding sysfs file works:
merkaba:~> echo 1 > /sys/module/snd_hda_intel/parameters/power_save
merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_saved
1
As I a workaround I use:
merkaba:~> grep power_save /etc/sysfs.conf
module/snd_hda_intel/parameters/power_save = 1
This works.
Yet the module actually has that parameters:
merkaba:~> modinfo snd_hda_intel | grep power_save
parm: power_save:Automatic power-saving timeout (in second, 0 = disable). (int)
parm: power_save_controller:Reset controller in power save mode. (bool)
Yet setting parameters for i915 works:
merkaba:~> cat /etc/modprobe.d/i915-kms.conf
# Thorsten Leemhuis, Die Woche: Ungenutztes Stromsparpotenzial
# http://www.heise.de/open/artikel/Die-Woche-Ungenutztes-Stromsparpotenzial-1361381.html

merkaba:~> grep . /sys/module/i915/parameters/*

/sys/module/i915/parameters/reset:Y
/sys/module/i915/parameters/semaphores:1
/sys/module/i915/parameters/vbt_sdvo_panel_type:-1
Expected results:
Setting parameters for snd_hda_intel works as well. I do not see any
obvious syntax errors in my snd-hda-intel.conf. I might have overlooked
some. If it has a syntax error please point me at it and feel free to
close the bug.
Thanks,
Martin

I cannot reproduce this.

What happens if you manually remove and then reload the module without
rebooting?

rebooting it does not. The manual case:
merkaba:~> modprobe -r snd_hda_intel
merkaba:~> lsmod | grep snd_hda_intel
merkaba:~#1> modprobe snd_hda_intel
merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save
1
merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save_controller
Y
Another test for the manual case:
merkaba:~> echo "0" > /sys/module/snd_hda_intel/parameters/power_save
merkaba:~> echo "N" >
/sys/module/snd_hda_intel/parameters/power_save_controller
merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save
0
merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save_controller
0
N
(I don´t think these above are necessary, but anyway.)
merkaba:~> modprobe -r snd_hda_intel
merkaba:~> modprobe snd_hda_intel
merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save
1
merkaba:~> cat /sys/module/snd_hda_intel/parameters/power_save_controller
Y
Now for the reboot case I disabled the sysfs.conf entry for setting it:
merkaba:/etc> vim sysfs.conf
merkaba:/etc> grep snd sysfs.conf
# Macht modprobe/kmod anhand von /etc/modprobe.d/snd-hda-intel.conf
derzeit nicht.
#module/snd_hda_intel/parameters/power_save = 1
Then I build a new initramfs with this configuration:
merkaba:/etc> cat modprobe.d/snd-hda-intel.conf
# c`t kompakt Linux 1/2012
# Thorsten Leemhuis, Notebooks unter Linux, S. 38ff
# S. 42, Kasten Handoptimiert
options snd_hda_intel power_save_controller=Y power_save=1
merkaba:/etc> update-initramfs -k all -u
# Thorsten Leemhuis, Notebooks unter Linux, S. 38ff
# S. 42, Kasten Handoptimiert
options snd_hda_intel power_save_controller=Y power_save=1

I can switch to using /etc/sysfs.d to set it.

In a normal configuration it would not be available there.
I did some tests with a different module which is available in the
initramfs and I am still unable to reproduce this:
#!/bin/bash
kver=3.16-1-amd64
opts+=(-m 256M)
opts+=(-curses)
opts+=(-kernel /boot/vmlinuz-$kver -initrd /boot/initrd.img-$kver \
-append 'break=top')
kvm "${opts[@]}"
