Running under Windows XP 64 bit, as.POSIXlt()/as.POSIXct() seem to think that US time zones (EST5EDT, MST7MDT) switched from daylight savings back to standard time on Oct 28, 2007, whereas the switch is actually on Sun Nov 04, 2007. Examples: > Sys.timezone() [1] "Mountain Daylight Time" > as.POSIXct("2007-10-30 12:38:47") [1] "2007-10-30 12:38:47 Mountain Daylight Ti...

...ing packets, ignoring configuration etc. I have likely missed a ton of clever ideas and older discussions, and probably misunderstood some code. Please pipe up with corrections, additions, etc. And please don't take offence if I didn't attribute the idea correctly - most of them are marked mst by I don't claim they are original. Just let me know. And there are a couple of trivial questions on the code - I'll add answers here as they become available.

Currently the way that we prevent userspace from performing new modesets on MST connectors that have just been destroyed is rather broken. There's nothing in the actual DRM DP MST topology helpers that checks whether or not a connector still exists, instead each DRM driver does this on it's own, usually by returning NULL from the best_encoder callback which in turn, ca...

...y - do you mean it doesn't yet work with vhost because of a vhost bug, and to test it with the linked patches you had to hack in _F_NEXT? Because I do not see _F_NEXT in indirect descriptors in this patch (which is fine).

This fixes some annoying issues on the P50-P52 with displays not being detected if they aren't plugged in at boot, and sometimes even when they are plugged in at boot.
