Title:
  [bionic] high cpu load HP probook  iio-sensor-proxy

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have a many HP ProBook 450 G1 and HP ProBook 650 G3 with fresh
  install of Ubuntu Desktop.

  They all have a load average of 1.0 when idle (no graphical session
  opened).

  vmstat shows idle =~ 100%

  The process which uses most CPU time is iio-sensor-proxy (about 1%)
  and it's constantly in D state (uninterruptible sleep).

  Manually starting this command shows that the sensor (lis3lv02d on
  both products) is constantly sending garbage informations (see
  attachment).

  With iio-sensor-proxy service stopped, the CPU load is ~ 0%

  As the service is 'static' and can not be disabled, the only workaround is to 
remove the 'iios-sensor-proxy' package.

Looks like the sensor has different mappings for different HP models.
Can you refer to [1] to see what mapping really works for your models?

Maybe run `watch -n0 cat /proc/interrupts` and see if there's any
spurious interrupt.

2018-07-23 Thread Ludwin Janvier
upstream (iio-sensor-proxy, not the kernel project) classified this bug
as "won't fix" because "Load average is not a good representation of the
CPU (or other resource) usage caused by an application."

Can someone confirm this information?

Title:
  [bionic] high cpu load HP probook  iio-sensor-proxy

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have a many HP ProBook 450 G1 and HP ProBook 650 G3 with fresh
  install of Ubuntu Desktop.

  They all have a load average of 1.0 when idle (no graphical session
  opened).

  vmstat shows idle =~ 100%

  The process which uses most CPU time is iio-sensor-proxy (about 1%)
  and it's constantly in D state (uninterruptible sleep).

  Manually starting this command shows that the sensor (lis3lv02d on
  both products) is constantly sending garbage informations (see
  attachment).

  With iio-sensor-proxy service stopped, the CPU load is ~ 0%

  As the service is 'static' and can not be disabled, the only workaround is to 
remove the 'iios-sensor-proxy' package.

2018-06-26 Thread Joseph Salisbury
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

Title:
  [bionic] high cpu load HP probook  iio-sensor-proxy

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have a many HP ProBook 450 G1 and HP ProBook 650 G3 with fresh
  install of Ubuntu Desktop.

  They all have a load average of 1.0 when idle (no graphical session
  opened).

  vmstat shows idle=0% and waiting=~ 100%

  The process which uses most CPU time is iio-sensor-proxy (about 1%)
  and it's constantly in D state (uninterruptible sleep).

  Manually starting this command shows that the sensor (lis3lv02d on
  both products) is constantly sending garbage informations (see
  attachment).

  With iio-sensor-proxy service stopped, the CPU load is ~ 0%

  As the service is 'static' and can not be disabled, the only workaround is to 
remove the 'iios-sensor-proxy' package.
