Compiling kernel IEGD 10.x module for any Linux distribution

Intel has put great effort to put complete open-source drivers into recent kernels for its devices. Only device that is clearly missing there is GMA500 (aka Poulsbo, aka US15 chipset, aka Atom Z5xx family). This is understood as it does relay on Imagination Technologies PowerVR core licensed out by Intel to produce GMA500, so most of the driver parts cannot go open-source as it would imply of violation of some agreement between ImgTec and Intel.

Fortunately Intel provides binary driver set called Intel® Embedded Graphics Driver (IEGD) supporting all embedded video chipsets, containing binary form of video driver libraries for latest Xorg, OpenGL and VA.

While most of the work you need to do is to have IEGD_10_3_Linux.tgz file (in case of IEGD 10.3) extracted onto the target box and to copy various .so files in proper places (follow IEGD documentation). Yet there is one more complicated thing extra – IEGD Kernel Module (IKM) iegd_mod.ko that has to be compiled out of the source shipped with IEGD.

Linux Kernel module

IEGD documentation clearly states that only few distributions are supported by this driver, and those are i.e. Fedora 8 & 10, some older Ubuntu 8.x and finally Moblin. But what about others, such as Debian, newer Ubuntu. You think you are unlucky running other distro? You shall understand word “supported” here as “tested”.

Reading the documentation, in all cases your are supposed to enter IKM folder of extracted drivers and launch install.sh script. This script shall compile and install without any hassle IKM on “supported” distributions. Surprisingly trying that on your distribution even it is not supported may work too! With one important exception it produces bogus driver that will crash your kernel.

Finding the proper way for your distribution

This recipe will save some few hours upto few days of struggling with fancy errors trying to compile and run the IKM module on your system

Investigating the driver and install.sh first thing to notice is that it checks you Kernel version, it also takes (false) assumption that your are running one of the “supported” distros, so i.e 2.6.27 may mean Fedora version of the 2.6.27 Kernel not any 2.6.27 kernel.

Linux distributions have this fancy characteristic that they usually come with heavily patched kernel, so when you take 2.6.xx driver module from one distro and try to run it on the same version kernel on the other distro it will likely crash your kernel. Why? Incompatible ABI.

What Intel (Tungsten?) did in IKM is prepared IKM/val subfolder with headers extracted from several kernel sources of “supported” distributions. And what install.sh does, it tries to guess which one of DRM and AGP kernel module headers placed in that subfolder are OK for your Kernel.

In case you are running on the “unsupported” distribution the answer in 95% cases is NONE! Even you will be able to compile the iegd_mod.ko using Makefile produced by install.sh the module will crash you kernel as soon you will try to use it. Since your kernel has incompatible ABI (different structures) with the ABI provided inside IKM/val subfolder.

Preparing for compilation of IKM for your own kernel

If you are running “unsupported” distribution you should avoid then using headers in IKM/val subfolder. The right way is to take AGP and DRM headers out of your running kernel sources (you don’t have to compile the whole kernel of course).

So go to IEGD_10_3_Linux folder and launch:

sudo apt-get install linux-headers-x.y.zz
apt-get source linux-image-x.y.zz

Where x.y.zz is your running kernel version. (Use your own distro command to grab kernel source if you don’t run on Debian or Ubuntu)

This will install kernel headers and scripts to build kernel modules and also produce linux-x.y.zz folder containing source code of your running Kernel. The whole trick if to place (replace) Makefile in IKM folder as below:

KERNELVER ?= $(shell uname -r)
KERNELDIR ?= /lib/modules/$(KERNELVER)/build
INSTALLDIR ?= /lib/modules/$(KERNELVER)/kernel/drivers/char/agp
PWD ?= $(realpath .)

EXTRA_CFLAGS += -I$(PWD)/include
EXTRA_CFLAGS += -I$(PWD)/../linux-$(KERNELVER)/drivers/char/agp
EXTRA_CFLAGS += -I/lib/modules/$(KERNELVER)/build/include/drm

all: clean modules

modules:
	@echo $(PWD)
	@$(MAKE) -C $(KERNELDIR) M=$(PWD) modules

install:
	install -o root -g root -m 755 -d $(INSTALLDIR)
	install -o root -g root -m 744 iegd_mod.ko $(INSTALLDIR)
	/sbin/depmod -a

uninstall:
	rm -rf $(INSTALLDIR)/iegd_mod.ko
	/sbin/depmod -a

clean:
	@rm -f *.o iegd*.ko iegd*.mod.c iegd*.o agp/*.o drm/*.o Module.symvers
	@rm -fr .intel* .tmp* .*.cmd agp/.*.cmd drm/.*.cmd

obj-m := iegd_mod.o
iegd_mod-objs := agp/pci.o agp/global.o agp/drv_alm.o agp/drv_nap.o agp/drv_plb.o agp/drv_cmn.o agp/drv_gn4.o drm/iegd_drv.o drm/iegd_interface.o drm/iegd_interface_265.o drm/iegd_interface_2611.o drm/iegd_interface_2615.o drm/iegd_interface_2624.o drm/psb_irq.o

You don’t need to launch install.sh at all. Just paste the file as above.

As you see now, this Makefile references to ../linux-$(KERNELVER) for your running Kernel source AGP & DRM headers. Yet however you may still need to do few tweaks in your Makefile, see notes below:

Note (1) In case you are running older kernel, /lib/modules/$(KERNELVER)/build/include/drm may not exist, then $(PWD)/../linux-$(KERNELVER)/drivers/char/drm should be right path to put in the Makefile instead.

Note (2) The Kernel source code folder you downloaded (i.e. via apt-get source) may not actually match exactly linux-$(KERNELVER), so you may change that EXTRA_CFLAGS setting manually:

In case of Ubuntu `uname -r` is 2.6.31-19-generic while the extracted source folder name has no -generic suffix and it is just linux-2.6.31-19.
In case of Debian `uname -r` is 2.6.26-21 while the extracted source folder name is linux-2.6-2.6.26-21. Weird huh?

Final fixes before compilation

There is a file still missing if you try now to `make`. It is file that exists in IKM/val/agp but does not exist in your $(PWD)/../linux-$(KERNELVER)/drivers/char/agp. It is called interface_abs.h.

Wonder why the heck it is NOT in IKM/include!? This is a little lack of consequence from Intel here.

Anyway just copy interface_abs.h into IKM/include out of IKM/val/agp/agpm0vmob2 if you are running on >= 2.6.30 Kernel or from IKM/val/agp/agpm0v103 otherwise. The only difference between interface_abs.h from agpm0vmob2 and agpm0v103 is one macro definition.

Finally we need two little extra fixes.

(1) Trying to compile on Debian Lenny we will get many nasty errors from kernel headers for IKM/drm/iegd_interface.c. Moving igd_abs.h inclusion in this source file little down fixes the issue. Edit IKM/drm/iegd_interface.c as below:

 #include "iegd.h"
-#include "igd_abs.h"
 #include "drmP.h"
 #include "drm.h"

+#include "igd_abs.h"
 #include "iegd_drm.h"
 #include "iegd_drv.h"
 #include "psb_intregs.h"

(2) IKM/drm/iegd_drv.c tries to include linux/config.h at the very begining of the file. This is not actually necessary, and anyway does not exist, so you may comment that out:

-#include <linux/config.h>
+/* #include <linux/config.h> */

Compiling at last

Now you are ready to so `make` and `sudo make install`. This time iegd_mod.ko should be ABI compatible with your kernel.

I have tested this method on Debian 5.0 Lenny and Ubuntu 9.10 Karmic Koala.

To ensure everything works fine after driver installation try:

sudo modprobe iegd_mod

And try to go into IKM/agp and compile and run agp_test.c:

gcc -o agp_test agp_test.c
sudo ./agp_test

Next try the same with IKM/drm compiling and running drm_test.c.

If those two test won’t fail and won’t blow your kernel it means you have fully working IEGD module on your own Linux distro.

Notes for users of old psb-modules or psb-kernel-source Ubuntu package

Older psb-modules and psb-kernel-source Ubuntu packages install their own incompatible drm.ko module at /lib/modules/`uname -r`/updates/char/drm.

Check find /lib/modules/`uname -r` -type f -name 'drm*' you should have only one: /lib/modules/`uname -r`/kernel/drivers/gpu/drm/drm.ko

In case if you find other drm.ko, probably in updates/char/drm delete it. That one came from psb-kernel-source and is causing you a trouble. You may ensure you got only valid drm.ko reinstalling your kernel image with:

apt-get install --reinstall linux-image-`uname -r`

Notes for curious

The difference of Makefile of mine and Makefile produced of install.sh is the beginning:

KERNELVER ?= $(shell uname -r)
KERNELDIR ?= /lib/modules/$(KERNELVER)/build
INSTALLDIR ?= /lib/modules/$(KERNELVER)/kernel/drivers/char/agp
PWD ?= $(realpath .)

EXTRA_CFLAGS += -I$(PWD)/include
EXTRA_CFLAGS += -I$(PWD)/../linux-$(KERNELVER)/drivers/char/agp
EXTRA_CFLAGS += -I/lib/modules/$(KERNELVER)/build/include/drm

If you try to run install.sh EXTRA_CFLAGS will include two of IKM/val folders which contain some Kernel source extracted header definitions that are likely not compatible with your Kernel.

I use also PWD ?= $(realpath .) here instead of PWD ?= $(shell pwd) because with some Linux headers versions $(shell pwd) resolves to /lib/modules path not the path where IKM sources are.

Notes for Intel

It would be nice for next IEGD release if IKM source tree would be made for readable and clear:

IKM/val should be renamed to IKM/kernel-headers (what the heck “val” means here ?!) and this should be noted somewhere in docs that files here are NOT made by Intel but extracted of “supported” Linux distributions Kernel sources
interface_abs.h should moved away from IKM/val (IKM/kernel-headers) to avoid confusion (with point 1) and placed into IKM/includes (and there should be #ifdef for this one macro that makes it different for across 2.6.30)
IKM/drm/iegd_interface.c should be fixed as described above (moving iegd_abs.h inclusion little bit down).
IKM/drm/iegd_drv.c inclusion of <include/config.h> is not necessary, may be removed.
Finally install.sh should contain case when running on “unsupported” distribution.
So it shall make SURE if running on “supported” distributions and then and only then use files from IKM/kernel-headers, OTHERWISE ask for a path for your own Linux distribution Kernel source’s to find a path for your own kernel/drivers/char/agp and kernel/drivers/char/drm (include/drm) i.e. by showing:
```
Your Linux distribution and Kernel version was untested, however you may try to compile and run driver on your own risk.
Please provide your running kernel sources extracted i.e. on Debian or Ubuntu using apt-get source linux-image-2.6-686:
[path to your kernel]:
```

@ishu: Thanks for the feedback! I updated my recipe and added one extra point for Intel consideration – IKM/drm/iegd_drv.c inclusion of <include/config.h> is not necessary, may be removed.

@denis:
1. IEGD_10_3_Linux.tgz lays somewhere at extracted IEGD folder/installation made out of EXE available from Intel (so yes… you do need Windows or Wine to get it extracted)
2. Correct
3. Correct (I forgot about this case, but indeed I had to do the same, updated my recipe, you may also change this path in the Makefile)
4. Correct (I’ll have a look how this can be copied&pasted without need to changing tabs to spaces)
5. Correct (my mistake, fixed)
6. You may freely comment out this include, it is not necessary anyway (I updated my recipe)
Let me know if you succeeded and thanks for you comment.

Adam,

You really need to post links to this on all the forums discussing IEGD. I have spent 4 days trying to get the kernel module to compile on kernel 2.6.32.8 and xserver 1.6.3.901. I finally got it compiled but crashed. Then I came across this instrution. You perfectly explained the problem and the solution. Within 30min I had it up and running. I owe you big time.

I have an Acer AO751h with the US15W/GMA500 chipset.

thank you, thank you, thank you!

Hi Adam,

after removing #include <linux/config.h> things look very promising and the module will be compiled without errors. make install runs fine, too but:

@Sambhav: Ensure you got interface_abs.h copied to IKM/include from IKM/val/agp/agpm0vmob2 not other IKM/val/agp/...

February 23rd, 2010 at 00:53 Pietro

@ Sambhav
I had the same problem. I sobstituted line 594 of drv_cmn.c with this :

unsigned long address = page_to_phys(addr);

(see http://ubuntuforums.org/showpost.php?p=8479406&postcount=6)

and I was able to compile the driver. However that solution could be complitely wrong and I was unable to test the driver becouse dmesg says:

drm_psb: exports duplicate symbol drm_order

And now is time to go to bad

Hi Adam,

Thanks. I was able to compile IKM and install IEGD 10.3 on Ubunut 9.10
My app is not decoding P frames properly in IEGD 10.3.
Proper decoding was happening on IEGD 10.2.
After switching to 10.3 only I frame is getting decoded properly. My decoder support only I and P frames.
Is there any change in the interpretation of the data between the 2 versions ?

Regards,
Sambhav

February 23rd, 2010 at 15:57 Adam

@Sambhav: I have absolutely not idea what has changed between 10.2 and 10.3. I am not Intel’s employee, and can’t tell anything about VA (or GL) drivers that are available only in binary form, even I wish to. I have also hit few showstoppers with IEGD drivers that made me stuck with my application. One of them is latest IEGD VA drivers are unable to handle multithreaded apps. Application simply crashes everytime you try to access VA driver from multiple threads.
While it was working fine with so called PSB drivers from 2008, it doesn’t work anymore with latest IEGD.
I think you can post about your problems here: http://community.edc.intel.com/
From my side I am trying to apply for some CNDA trough EDC site, so I can have some support ticket for my problems. I think this is most resonable solution there.

February 23rd, 2010 at 16:14 Sambhav

Adam,

Thank you.
I have posted the problem in Intel Support.
I see my multithreaded app crash after I switched to Ubuntu 9.10 and Moblin IVI 2.1 (both with X-server 1.6.x) with IEGD 10.2 and 10.3.
My suspicion is on the X-server version (not sure)
But the same multithreaded app used to run fine with Ubuntu 8.04 with IEGD 10.2.

Thanks again for the article.

Sambhav

Adam,

As with the rest of the posters here, I’d like to take a moment to thank you for this walk through.
Because I am a Acer Aspire One 751h owner I’ve been wrestling with the psb-modules and psb-kernel-source
packages since day one and as such am seriously looking forward to testing these new Intel supported drivers.

Have you noticed any improvements performance wise after making the move to IEGD?

Regards,

JoshG

February 24th, 2010 at 16:39 cgriffith

JoshG,

I have to say that the 10.3 drivers do show increased performance in a very non-emperical way. Before I used these drivers, I was unable to watch movies because frame dropping made it unbearable. Now I can. However, there are serious instability issues. I can not suspend or hibernate, If I switch between X and virtual terminal, I get a kernel panic. If my desktop goes into powersave mode, I am unable to recover. And under some (non-reproducible) circumstances, the system just hangs. Not sure it is worth it.

I look forward to hearing how others mileage turns out. FYI, I am using an AO751h, with kernel 2.6.32.8 and xserver 1.6.3.901.

February 25th, 2010 at 12:38 billiob

Does this driver work with xserver 1.7?
20
February 25th, 2010 at 13:24 Adam

@billiob: Probably not since IEGD is shipped with Xorg drivers up to 1.6.4 version, so Xorg gonna complain about incompatible release number.

Could someone tell me Where can I get the package IEGD_10_3_Linux.tgz Please???
Thankyou!!!

Hi

Thanks to your howto, I made a package for openSUSE :
http://download.opensuse.org/repositories/home:/vlj:/IEGD/standard/
I would like to get a working xorg.conf ; mine is not optimal, for instance I cannot get vt switch to work (when i hit ctrl alt f1 my display freeze),
compiz/kwin dont work, and openarena is very very slow (5 fps at min settings…on windowsseven it’s around 30fps at max settings with IEGD 10.3).
I get 2500 frame in 5 sec under glxgears.

I pretend to compile IEGD 10.3.1 on my Ubuntu 9.10
I have downloaded the moblin version (because I think this is the most similar to Ubuntu) but I obtain just what seems to be a Windows version!

Any hints on how to download the Linux version of the IEGD?

Hi,
As IEGD require xserver 1.6, I did rebuild the debian package of the old xserver 1.6 with the rest of xorg 7.5 basically unmodified. And this worked !
The explanations and debian (squeese) packages are on my blog:
http://silicone.homelinux.org/2010/04/11/building-xserver-1-6-for-xorg-7-5/

This blog was a great help for building the IKM, so thanks a lot !

Sometime X freezes, I wonder wether my xorg build is bad or if other IEGD users experienced the same (this would be an intel bug then).

Can you just fix my name in my previous comment while moderating it. Thanks.

Also I probably should have written: “Your blog was a great help for building the IKM, so thanks a lot !” instead…

Great guide!!!

The 10.3.1 IEGD Driver has a quite good performance (glxgears) compared to previous releases. However, I’ve some problems in my virtual terminals.

When I switch to a virtual terminal (Ctrl + Alt + F1), it uses a resolution that my display does not support. Is there any way to change it???
33
April 16th, 2010 at 15:14 cgriffith

@jsabater

I had seen a similar issue (I think). When I switched to a virtual terminal, I saw eight small versions of the console. I rebooted and added vga=792 to boot parameters and now it works fine. I surmised that something got confused and did not know what resolution to use, but since I explicitly stated it, it now knows.

Hi Adam,

I found your site and am trying to compile IKM for a 2.6.32.11-kernel.

Hi – just looked at the intel site for the download and its a wopping 130meg! This is ludicrous for a kernel and X module. Add to that i have no windows box and no desire to install wine. Can anybody provide a link to the tar.gz required? i would be most greatful.
37
April 30th, 2010 at 15:40 Adam

@gforums: Make sure your Makefiles EXTRA_CFLAGS is pointing to existing directories (one of them should contain agp.h)

@Espionage724: Well this is main distro I have used for IEGD compilation. Try, if you have any trouble please post below.

@mangodan: I am afraid we can’t give you any link to that TGZ that is contained in IEGD installer. Only thing you can do is ask Intel at their forums at edc.intel.com. Those are their drivers and software so distributing it without their permissions can have legal consequences.

Hi !

Thanks for this article, it is really useful.
I’ve got a problem. I’ve compiled the driver correctly but when I insert it with insmod or modprobe, I’ve got this error : iegd_mod : Unknow symbol drm_irq_install.

I’ve tested to unload drm.ko and to reload it, but I’ve the same error…

Thanks for your help!
39
May 11th, 2010 at 19:31 Adam

@RH: Can you check you don’t have somewhere in modules directory another drm.ko file hanging around, like older one coming with Poulsbo driver?
40
May 12th, 2010 at 12:16 RH

I’ve checked and there is no drm.ko in the directory. DRM is integrated in the kernel (not in module mode). Is it the reason why it doesn’t work?
41
May 12th, 2010 at 17:10 RH

I have externalized the drm driver, and there is no problem with it. The iegd driver has the same problem with the drm externalized driver…
42
May 12th, 2010 at 17:49 RH

Ok I know the problem :
- In the file iegd_interface.c, the function drm_irq_install is declared only if you have a kernel < 2.6.27.7. But I have a 2.6.27.7 kernel and in the include file (drm.h and drmP.h) of the kernel, this function is not declared. So I modified each test to kernel <= 2.6.27.7

But yet I have another problem… Other functions are not declared in my drm version.. Do you know if it is possible to upgrade the drm version of the kernel? If yes, do you have link where I can download a newer version? Or am I obliged to change the entire kernel version?

Thanks for yout help

I have a Dell mini 12 with GMA 500 on which Karmic Koala i386 is loaded ; I never installed psb* DEB packages on this box.

I have carefully followed the instructions with IEGD 10.3.1 and I managed to compile, load and install the drivers without problem. Then, I installed the Xserver librairies provided by IEGD for Xserver-1.6. I wrote an xorg.conf file with samples I found on the net… but my Xserver segfaults, and I don’t find anything relevant in Xorg.0.log apart from the backtrace. My kernel logs display one error :

[IEGD]: Registering iegd gart module
[IEGD]: Initialize IEGD agpgart and drm
[IEGD]: Intel US15 chipset detected
[IEGD]: Detected 7932K stolen memory.
iegd-intel 0000:00:00.0: AGP aperture is 256M @ 0x3f800000

I have uploaded at this address http://people.via.ecp.fr/~alexis/mini12 all the relevant information : Xlog.0.log (which includes backtrace), dmesg, xorg.conf, lspci, lsmod, etc….

Any ideas ?

May 22nd, 2010 at 01:39 Adam

Ugh… sorry guys, but I haven’t tested this stuff with latest kernels, neither did Intel I guess, so if you want those drivers running you need max 2.6.32 I suppose.

Could you please explain this part to a newbie:
Note (2) The Kernel source code folder you downloaded (i.e. via apt-get source) may not actually match exactly linux-$(KERNELVER), so you may change that EXTRA_CFLAGS setting manually:

In case of Ubuntu `uname -r` is 2.6.31-19-generic while the extracted source folder name has no -generic suffix and it is just linux-2.6.31-19.
In case of Debian `uname -r` is 2.6.26-21 while the extracted source folder name is linux-2.6-2.6.26-21. Weird huh?

I am running Ubuntu. I get a failure to compile similar to another Q here.

Lets say I am running 2.6.31-22-generic and want to compile the IKD. What edits to the makefile do I need to do. I have tried a bunch of stuff and am not having any luck. Could you provide an example?

also, I cannot install the kernel source as you describe above. This may be because I am not running the latest kernel, but still, it errors out:

apt-get source linux-image-2.6.22
$> sudo apt-get source linux-image-2.6.31-22
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to find a source package for linux-image-2.6.31-22

It is possible to build it under Debian sid with kernel 2.6.32-trunk-686 (linux-2.6.32-5-686 (20)) [iegd 10.3.1]

Additional point for the instructions above have to be added:
agp/drv_cmn.c:#define phys_to_gart(x) (x)
Xorg 1.6.5 works good
Videos in h262 are much better to see then under psb driver.
