I have a couple of basic questions regarding the setup and performance of the Linux MSDK. I have an i7-4770R Iris Pro processor system. Clean Ubuntu system setup. No additional hardware drivers installed. I searched Intel for Ubuntu 12.04LTS display drivers and did not find any. MSDK setup based on Linux Server Release Notes (Ver. 5.0.1603329.77219). System then has Ubuntu 12.04.4LTS 64bit, Kernel 3.8.0-23, MDSK Linux Server 16.3.15249_64bit, and libva 1.3400.0.
1) During the install of MSDK I 'lspci -nn' returns the following
"00:02.0 VGA compatible controller : Intel Corporation Device [8086:0d22] (rev 08)"
This seems to be more generic than for others Intel systems where Haswell often gets listed. Is this sufficient for the install and MSDK to run properly? Should I install any additional apt-get packages?
Also "lsmod | grep i915" tells me that the module size of the i915 is 608071. Smaller size than the one listed in instructions but I am assuming this is not an issue.
2) After MSDK installation, when I run the sample_decode_drm with the "-hw" option on a 60minute 480x270 @ 30fps H264 stream the decoding takes roughy 11minutes. Same decode with the "-hw -vaapi" option runs considerably slower ~ 60 minutes. Is this an expected behavior? If so, why is that?
Want to check that I am not missing something basic in the system installation.
