<pre>Hi Daniel.
About the 3.9 RC kernels - I will be able to test it when it hits the ArchLinux
testing repository. Never compiled kernel from the source in my life and I know
it would take a long time on this single core celeron CPU and it would render
it useless / unusable during the process. Also my connection has a 20 gigs per
month download limit and downloading kernel source from git repository would
take a nice bite out of it. I hope it's ok.
Installed the intel-gpu-tools as asked and downgraded kernel to the working
3.7.9-2 one and rebooted:
[root@wishmacer ~]# pacman -Ss intel-gpu-tools
community/intel-gpu-tools 1.3-2
Tools for development and testing of the Intel DRM driver

[root@wishmacer ~]# reboot
Now about the command that You asked me to test... There is a problem I
think... Dump file comes up empty? Am I doing it wrong?
WORKING KERNEL
[andrzejl@wishmacer ~]$ uname -a
Linux wishmacer.loc 3.7.9-2-ARCH #1 SMP PREEMPT Mon Feb 25 12:29:24 CET 2013
i686 GNU/Linux
[andrzejl@wishmacer ~]$ su
Password:
[root@wishmacer andrzejl]# sleep 30; intel_reg_dumper > dump
Gen2/3 Ranges are not supported. Please use unsafe access.Aborted (core dumped)
[root@wishmacer andrzejl]# ls --full ./dump
-rw-r--r-- 1 andrzejl users 0 2013-04-02 13:17:36.629652278 +0100 ./dump
[root@wishmacer andrzejl]# du -h ./dump
0 ./dump
[root@wishmacer andrzejl]#
I went to the #intel-gfx channel and was told:
14:16 < AndrzejL> I was told to provide intel_req_dumper dump
14:17 < AndrzejL> but it says I need to enable the unsafe access but there is
no "--unsafe-access" like switch
14:17 < danvet> AndrzejL, have you tried the latest version from git?
14:17 < danvet> iirc we've broken a few things ...
14:24 < AndrzejL> would I compile git stuff or is there another option?
14:28 < danvet> AndrzejL, compiling from git is the preferred option
So... now I am running this version:
[andrzejl@wishmacer ~]$ su
Password:
[root@wishmacer andrzejl]# pacman -U

[root@wishmacer andrzejl]#
Which has replaced the previous version from stable repo.
It gives me the same error message:
[root@wishmacer andrzejl]# intel_reg_dumper > dump
Gen2/3 Ranges are not supported. Please use unsafe access.Aborted (core dumped)
[root@wishmacer andrzejl]# du -h ./dump0 ./dump
[root@wishmacer andrzejl]#
and again a 0 bytes sized dump file.
I had to modify the source code...
debug-rdata.c
intel_reg_dumper.c
- intel_register_access_init(pci_dev, 1);
+ intel_register_access_init(pci_dev, 0);
as I read here:
<a class="bz_bug_link
bz_status_RESOLVED bz_closed"

AND... after reinstalling the package:

I get the exact same error...

[root@wishmacer andrzejl]#
I am getting frustrated... Kernel modesetting seems broken. I cannot debug it
for you coz debug tool seems broken...
Must be my lucky day...
Cheers.
