Description Jason Vas Dias 2016-04-25 23:56:58 UTC
Having checked out & built the latest xf86-video-intel source code from git:
  $ git tag | while read tag; do echo $(git show --format='COMMIT_TIME:%ct' "$tag" | sed -n '/^COMMIT_TIME:/{s/^COMMIT_TIME://;p;}') "$tag"; done | sort -n | tail -n 1
  1419172872 2.99.917
  $ git checkout -f 2.99.917
( which is from rather a long time ago - 2014-12-21 - but is latest version
  in GIT as of writing : 2016-04-25)
, against latest version of Xorg server from GIT : 1.18.3 , 
and all of its dependencies from their latest GIT versions,
it initially failed to build because evidently the prototype of 
the server's PixmapSyncDirtyHelper has changed:

, and once it did build , then it generates a segmentation violation (SIGSEGV)
and would core dump if ulimit allows - here is the gdb stack trace of the 
Xorg server version 1.18.3, with which this version of xf86-video intel seems
not to be fully compatible:

As you can see, the kgem->retire function pointer is NULL. 

The above leads me to suspect this package is no longer maintained /
kept working with recent versions of the Xorg software stack - is this
the case ?

Any suggestions how to fix to make it work with latest Xserver 1.18.3 ?

If I just make the modification to sna/kgem.c :

+++  if( kgem->retire != NULL ) 
         kgem->retire(kgem);

rather than letting it core dump, then the Xserver hangs and 
never goes into graphics mode - it wrote this line to the log:

[   809.057] (II) GLX: Initialized DRI2 GL provider for screen 0

but never displays any graphics or proceeds any farther.

Is there a recommended X-server version this version of xf86-video-intel
is known to work with ?
Comment 1 Chris Wilson 2016-04-26 05:12:12 UTC
You checked out the latest then didn't build it?
Comment 2 Jason Vas Dias 2016-04-26 14:09:35 UTC
(In reply to Chris Wilson from comment #1)
> You checked out the latest then didn't build it?

Good day Chris - thanks for responding!

You replied to this bug report before reading it ? :-)

As I said :

                     ^^^^^^^
>   $ git tag | while read tag; do echo $(git show --format='COMMIT_TIME:%ct' "$tag" | sed -n '/^COMMIT_TIME:/{s/^COMMIT_TIME://;p;}') "$tag"; done | sort -n | tail -n 1

>  $ git checkout -f 2.99.917


I did check out and build ALL dependencies of ALL Xorg libraries to their
latest GIT tags, as shown by the output of the command :

$ for p in xserver driver/*/. proto/*/. lib/*/. util/*/. ; do
    p=${p%/.}; cd $p && 
    echo '*** '"${PWD//*xorg\//xorg\/} $(\
    git show --format='.:%ci %H' $(git_mrt) | 
        sed -rn '/^.:/{s/^.://;p}'$'\n''/^[Tt]ag/{p}'; 
    git show --format='.:%ci %H' | 
    sed -rn '/^.:/{s/^.://;p}';)" && 
    cd $SRC/xorg; 
   done 2>&1 | tee versions.lst.txt

All directories shown in versions.lst.txt (appended) have been
built and installed with gcc-5.3.0  & binutils-2.26.20160125
for glibc-2.23 on an x86_64 platform: 
( CPU:  
vendor_id       : GenuineIntel
cpu family      : 6
model           : 60
model name      : Intel(R) Core(TM) i7-4910MQ CPU @ 2.90GHz

VGAs:

).

xf86-video-intel has not been modified since :

*** xorg/driver/xf86-video-intel tag 2.99.917
Tagger: Chris Wilson <chris@chris-wilson.co.uk>
2014-12-21 14:41:12 +0000 baec802b21387d04aebb10ac29e719a1800c5aa0
2014-12-21 14:41:12 +0000 baec802b21387d04aebb10ac29e719a1800c5aa0

but theer have been MANY X-server releases since then, 
and obviously version 2.99.917 seems to be rather out
of sync with the latest X-server 1.18.3 .

Can we expect an upgraded xf86-video-intel driver anytime soon ?

Comment 4 Jason Vas Dias 2016-04-26 14:19:44 UTC
BTW if I try and build the Xserver circa 2014-12 :
  xorg-server-1.16.99.902
it no longer builds against newer EGL / GLX libraries.
Comment 5 Jason Vas Dias 2016-04-26 14:39:13 UTC

Comment 8 Jason Vas Dias 2016-04-26 15:16:31 UTC
That was from run of command:
  $ export DISPLAY=:0; Xorg -logverbose 7 :0 vt04 & (sleep 2; xterm &)
that didn't coredump after application of patch:
     if( kgem->retire != NULL ) kgem->retire( ...
to kgem.c .
But this just hangs, and xterm is unable to open display.

I think that the action of checking in a version of an Xorg module
should imply "works with current versions of all this package's dependency 
Xorg modules" .  Please correct me if this is not the case. 

All I am asking is : when / will / can the xf86-video-intel driver be 
fixed to work with X-server 1.18.3 ?
Comment 9 Jason Vas Dias 2016-04-26 15:57:20 UTC
Doesn't the fact that kgem->retire is being attempted to be called by
the xf86-video-intel driver indicate
that the xf86-video-intel driver is in effect "giving up" and refusing
to control the screen, which it thinks is controlled by the Radeon 
driver, but the Radeon card is not in fact connected to the laptop
LCD output, which is only controlled by the Intel IGP card ?
So in this scenario , with no xorg.conf, all drivers have given up 
and no driver agrees to control the laptop display ?
Comment 10 Jason Vas Dias 2016-04-26 16:11:20 UTC
There appears to be no xorg.conf that can handle this situation. 
I have tried :

A) no /etc/X11/{xorg.conf,xorg.conf.d/*} .
   Results shown above.

B) Cognizant of Intel Card only :

None of the above configurations work with latest Xorg-server 1.18.3 and
xf86-video-intel 2.99.917 and Linux 4.5.0 & versions shown in appended file.
Can anyone suggest how to get an X-Display configured with these versions 
on this hardware ?

Eureka! 
Xorg X-Server 1.18.3 & xf86-video-intel 2.99.917+ with kgem.c patch above 
X-Windows Initialization finally succeeded !
xterm displayed OK !

The magic undocumented xorg.conf incantations I had to type were :

 $ more /etc/X11/xorg.conf

I also had to install xkeyboard-config, which I had neglected, and to 
$ mount -t devpts /dev/pts
before xterm would work .

NOTE: without the patches to both src/uxa/intel_driver.c and src/sna/kgem.c
given above, xf86-video-intel A) does not compile with gcc-5.3.0; B) still
gets a core dump on kgem->retire() .

But really, if X-Server is incapable of operating without being told what
output to use via Device Section Option 'Monitor-DisplayPort-XXXXX' then
this ought to be properly documented somewhere .
I'd like to see an xf86-video-intel 'DisplayPort' option or an actual
X-Server command-line option like '-p / --port' eDP-1 .
