Hi all,
Please forgive me if I post my questions to the wrong place, but I don't know
where else to post.
I am new to graphic programming. I found that the Linux graphic architecture
is very complicated. Luckily I found an "Intel Graphics Stack" on 01.org. There
are 8 components in the 2013Q1 stack. Do all these eight components contain
Intel specific codes?
Take GM965 for an example, I found out that:
- kernel-3.8.2 has i965 codes for its DRM driver;
- mesa-9.1 has i965 codes for its DRI driver to support OpenGL API;
- xf86-video-intel-2.21.3 is a 2D acceleration driver for X Window;
- libdrm-2.4.42 has intel specific code too, it is used by Mesa;
- vaapi-intel-driver-1.0.20 is no doubt an intel product to support libva;
And what about the other three:
- Cairo-1.12.14
- Libva-1.1.1
- Xserver-1.13.2.902 ?
Do they have i960 specific code too? Or are they listed here just for compatibily
infomation?
I think these eight components can be divided into three types:
- 2D acceleration: xf86-video-intel. This part is always required;
- 3D acceleration: kernel DRM, mesa, libdrm. This part is optional if 3D accele-
ration is not needed;
- video acceleration: vaapi-intel-driver, libva. This part is optional if video
acceleration is not needed.
Am I right?
The last question is what is the roll of Cairo in this Graphics Stack?
Thanks.
Best regards.
