I am trying to understand if the long resume time is a graphics driver issue, and one thing I did was to take a new Ubuntu install (fully updated, i e just default graphics driver) and try on a Fusion E-350 and an Atom/ION2 system, and E-350 takes 17 secs, Atom 4 secs. One funny thing is that in syslog, both systems say resume took ~2.5secs, and both systems log all suspend and resume events with the same time stamp (i e suspend and resume according to log taking place at the same time..), perhaps it's just that the time stamps don't work during suspend, or perhaps it indicates whatever takes an extra 13 secs is before the PC is awake enough to log anything. Do you think it is graphics driver related? If not, I should take this question to another thread.
A completely different thing - I'm also trying to understand the status of this project especially when it comest to L5.1 support. At Phoronix they said yesterday that the XBMC team has said that XVBA "is still buggy and not actively progressing" while AMD recently said "H.264 Level 5.1 has been in the driver for some time but not enabled". Is it a correct assessment of the situation that everybody hopes AMD will release an SDK that makes L5.1 support etc available, but no one knows if & when this will happen (and if the new part is bug free), and until then AMD XVBA support is considered "buggy" and not too useful? I'm surprised how they mention VA-API as an option, I thought it was without leader and with the same L5.1 and refframe limitations, or does XVBA via VA-API work with L5.1 and refframes >4?
I wish there was a place with a complete and updated view on AMD HW acceleration, today there's this XVBA thread, the XVBA VAAPI thread, and there is this wiki but it is old and doesn't even mention XVBA. Not easy to get a full overview and to compare the options. Or am I missing something?
