Re: Need help reducing compilation warnings in CURRENT

Hi Craig,

I'll gladly help (good excuse to learn C), but looking at those errors
in general, one thing pops out:

The warnings are almost all in contrib/ areas. Hence, any fix might
want to probably be submitted to upstream first.

Correct me if I'm missing something obvious here please ;-)

 Hi,
 
 I've configured Jenkins to highlight compiler warnings and generate
 a table.  Jenkins also keeps track of new compiler warnings over
 time.  See:
 
 https://jenkins.freebsd.org/job/FreeBSD_HEAD/warnings7
 
 Can anyone help improve the code by periodically looking at this
 table and submitting patches to clean up the code?
 
 Cleaning up compiler warnings is always boring work, but it is good
 to clean up the code over time.

So,

here's what I know.

My UX32VD works okay if you back out

https://svnweb.freebsd.org/changeset/base/277959

The problem with it is, once you do back that out, you won't be able
to set the brightness anymore (via acpi_asus_wmi).

Adrian- do you remember where you found the backlight tunable and
which it was?

I could back out those changes, install stock lemul (instead of
backed-out 277959 + lemul), and see what happens.

 I tried that couple of days back. Yes, same problem: blank
 screen, no luck with any settings like backlight. I can easily
 ssh and reboot or CTRL-ALT-F1 and CTRL-C and reboot (you see
 nothing on the screen) :)
 
 ok. i really do bet it's a backlight config problem, and
 unfortunately I don't have the laptop to be able to debug it. Sorry
 :(

How did you make that happen? Do you have a diff you could share?

 - brightness control using the function keys (acpi_asus_wmi?)
 never really worked, neither before nor after the changes to
 drm2/i915.

Indeed. Do we actually have a tool with which I could ... keylog,
for lack of a better word, all ACPI events, send them (the event name,
debug info etc) to syslog, and so on?

If there was, I could take a crack at making those buttons work.

Hi Adrian,

Stefan is seeing the same issue I've started seeing in February.

We're both using ASUS UX32VDs
(https://wiki.freebsd.org/Laptops/ASUS_UX32VD).

What's the actual fix for it?
- -J


 Hi,
 
 How are things ? Still using Zenbook ?
 
 Im running out of ideas: it seems I cant update anymore my FreeBSD
  11 to latest HEAD release since Xorg refuses to work/start nicely
  on this laptop. Something broke down Xorg after drm2 update at the
  beginning of Feb 2015.
 
 I logged here the entire story: 
 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=198937
 
 Any tips very welcome. Are you using FreeBSD current on Zenbook ?
 
 Thanks,

There's a backlight_invert tunable/hint that you can set in
/boot/loader.conf . Try setting it to 1 and rebooting.

 Hi Johannes,
 
 i am experiencing a similar behavior on an Asus UX31A. The 
 display is active but brightness seems to be near 0 and 
 unchangeable.
 
 Reverting https://svnweb.freebsd.org/changeset/base/277959 made 
 me get full brightness again. Unfortunately, brightness changing
  does not work.
 
 
 Me too for my Asus UX32VD Notebook.
