Dear Vitaliy and Luca:

Thank you very much for your  mails.
I´m desperate because we have 8.000 Atom D2550 that don´t work like my 
customer need.
There are people from Intel and Red Hat trying to get a solution but they 
have no one.
Could you work together with them?
Could you help them in any way?

Thanks in advance.

Hi Vitaly...
I still have a gma500 devicd but it is closed in the wardrobe :)
I don't know if there is anything better of xorg-modesetting and 
gma500-gfx kernel module. So no opengl stack and just decent 2d 
acceleration.
I should give it a read and look for anything updated :)
Luca,

Can you help? ))

Regards,
Vitaliy.

Dear Vitaliy Kulikov : 

I would like help from you  about this issue. 

Thanks in advance.
DIBAL is a company that designs and manufactures scales. One of the most 
important product of DIBAL (Scale PC) uses a CPU microprocessor Intel Atom 
D2550 inside. The Intel web is 
http://ark.intel.com/es-es/products/65470/Intel-Atom-Processor-D2550-1M-Cache-1_86-GHz 


This microprocessor has embedded graphics chipset (GMA 3650). This chipset 
is designed by PowerVR as SGX545. Intel web: Intel® Graphics Media 
Accelerator 500 (Intel® GMA 500) 

The Intel GMA 500 series, also known by it's codename Poulsbo or Intel 
System Controller Hub US15W, 

This DIBAL product (PC Scale) uses Red Hat operating system. The GMA 3650 
chipset doesn’t have a well-supported driver. In fact none of the drivers 
that are published on the web runs on Linux. 
The Intel drivers for GMA3650 are: 

a)        File: Intel_GMA500-5[1].0.0.0040.tar.gz 
 
https://downloadcenter.intel.com/es/download/19158/Controlador-del-Acelerador-Intel-para-medios-gr-ficos-para-Linux- 

Driver del 2010.  2010/06/30 

b)        https://downloadcenter.intel.com/download/21938 
Driver 2012. 
File: cdv-gfx-drivers-1.0.3_bee.tar.bz2 
http://download.intel.com/support/motherboards/desktop/sb/enabling_hardware_accelerated_playback_fedora_16_v.pdf 


The Linux community developed a driver called gma500_gfx. There is a 
version of Red Hat using this driver but is not official. 
This graphic chipset according to Intel documentation supports 2D graphics 
acceleration. 

An application that runs on Chrome, apache and php works fluidly 
Another application that is functionally the same and runs on Java doesn’t 
work smoothly. 
Java developers say it doesn’t work smoothly because no hardware 
acceleration chipset is used. 

We executed the following test to try to assess the performance of the 
chipset: 
  
J2BENCH https://openbenchmarking.org/test/pts/j2dbench 
glxgears 

The results were as follows: 

a)        CPU Atom D2550. Operative System: Red Hat 6.6 Kernel 2.6.32 
.Graphic driver  VESA 
$glxinfo | grep render 
direct rendering: Yes 
OpenGL renderer string:  sofware acceleration 

Execution time for J2BENCH test   2 min 47 sec 
Glxgears test   84 FPS 

b)        CPU Atom D2550 Operative System:  Red Hat 6.6 Kernel 3.14.1 
Graphic driver gma500_gfx 
$glxinfo | grep render 
direct rendering: Yes 
OpenGL renderer string:  sofware rasterizer 

Execution time for J2BENCH test  57 sec 
Glxgears test   90 FPS 

Si revisamos el fichero Xorg.0.log parece que no está utilizando la 
aceleración de hardware. 
[27.978]  (II) AIGLX: Screen 0 is not DRI2 capable 
[27.979]  (EE) AIGLX: Reverting to software rendering 

c)        CPU with microproccesator i3-5010U. Operative System: Red Hat 
7.3 Graphic driver  Intel HD Graphics 5500 
$glxinfo | grep render 
direct rendering: Yes 
OpenGL renderer string:  Mesa DRI Intel HD Graphics 5500 (Broadwell GT2) 

Execution time for J2BENCH test  38 sec 
Glxgears test   6.500 FPS 


We need help in this respect: 


In option b “CPU Atom D2550 Operative System:  Red Hat 6.6 Kernel 3.14.1 
Graphic driver gma500_gfx”   

Are we using the maximum capacity of the graphics chipset? 

Is it possible to objectively measure the performance of this chipset? 

Is it possible to improve it? 

Is it possible to ensure that we are using hardware acceleration?
