[Libva] vainfo segfault on GM965

[Nicholas Andrade]

Hi all,
I am running into segmentation fault with vainfo from libva-1.4.1 on an Intel GM965/GL960 integrated graphics card using the libva-intel-driver-1.4.1    .  

Running vainfo, I see the following:<<<<<libva info: VA-API version 0.36.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib64/va/drivers/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_36
Segmentation fault
>>>>>With the following in my syslog:<<<<<vainfo[30098]: segfault at 28 ip 00007f1cca7b2b57 sp 00007fff8a64f750 error 4 in i965_drv_video.so[7f1cca771000+16c000]
>>>>>
Downgrading both libva & libva-intel-driver to 1.4.0, I no longer see the segfault however vainfo still fails:<<<<<libva info: VA-API version 0.36.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib64/va/drivers/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_36
libva error: /usr/lib64/va/drivers/i965_drv_video.so init failed
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
>>>>>
Using libva-1.3.1 & libva-intel-driver-1.3.2 had the same result as 1.4.0 (i.e. no segfault, same error).

If it helps, here's some additional details about the hardware:<<<<<$ /usr/sbin/lspci -xvvv -s 00:02.0

I'm not sure which other package versions are relevant; but in case it matters, this is on a Gentoo Linux (~amd64) system using: kernel 3.17.1gcc 4.7.3glibc 2.19
libdrm 2.4.58 xorg-server 1.16.1xf86-video-intel 2.99.916
mesa 10.3.1

Any help/suggestions would be appreciated on this.
Thanks,Nick
