[Libva] xorg configuration file for libva

[v sailaja]

Hi,

I pulled the libva into sandybridge with the xorg.conf as follows.


----------------start of file-------------

Section "Device"
    Identifier    "Intel Graphics Driver"
    Driver        "intel"
EndSection

Section "Monitor"
    Identifier    "Generic Monitor"
    Option        "DPMS"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Device        "Intel Graphics Driver"
    Monitor        "Generic Monitor"
    DefaultDepth    24
EndSection

Section "ServerLayout"
    Identifier    "Default Layout"
    Screen        "Default Screen"
EndSection

Section "ServerFlags"
    Option        "DontZap"  "0"
EndSection

--------------------------end of file--------------

I tried "vainfo" commnad for libva

vainfo output:
*Xlib: extension "XFree86-DRI" missing on display ":0.0".*





I modified the xorg.conf as follows. we are using the intel video driver.

----------------------------start if file--------------------------

Section "Device"
    Identifier  "Intel Graphics Adapter"
    Driver      "intel"
EndSection

Section "Monitor"
    Identifier    "Generic Monitor"
    Option        "DPMS"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Device        "Intel Graphics Adapter"
    Monitor       "Generic Monitor"
    DefaultDepth  24
    SubSection "Display"
        Virtual 1920 1080
    EndSubSection
EndSection

Section "Module"
    Load "dri"
EndSection

Section "DRI"
    Mode 0666
EndSection

Section "ServerLayout"
    Identifier     "Default Layout"
    Screen         "Default Screen"
EndSection

Section "ServerFlags"
    Option        "DontZap"  "0"
    Option        "AutoAddDevices"  "False"
EndSection
--------------------------------End of
file----------------------------------

Now vainfo is working.

vainfo output:

libva: va_openDriver() returns 0

The Graphics card Chipset is  "agpgart-intel 0000:00:00.0: Intel Sandybridge
Chipset"
VGA compatible controller: Intel Corporation Sandy Bridge Integrated
Graphics Controller (rev 09

Some test cases are there in libva, I tried all those. I didn't face any
problem.
But I want to enhance the Picture performance.

Is this xorg.conf is right or Whether i need to make some some changes??
Any help will be apreciated.[?]
