Intel's Unreleased 3.0 X.Org Driver Gets More Fixes For DRI3/Present

[axfelix]

I noticed that Arch recently removed DRI3 config details from their wiki: https://wiki.archlinux.org/index.php/intel_graphics

I think it was just leading to too many stability issues. Shame, because vsync is still broken under Gnome 3 / Intel DRI2...

try to use the debian/ubuntu version, they have some patchs

Yeah that's not gonna happen - distribution is not something that you change because it has some patches. I could take the patches they have and apply them to my tree, of course. However I doubt there's anything there that fixes these issues -- Chris (Wilson) was not able to quickly identify the issue, and my bug report has gone dormant... Dave (Airlie) wrote a patch to improve GLAMOR perf for modesetting, which helped but not enough.

Not a lot of alternatives... xf86-video-intel is broken for me on Skylake (terminal cursor/highlights don't update properly, in both xterm and aterm), and modesetting is slow-as-molasses (with the wator screensaver demonstrating that quite aptly).

i never had problems with sna but i agree they should make some stable snapshots, at least every year

maybe they release v3.0 in the year of the Linux desktop - that could be either 2017 or 2018, or if we are unlucky any other year thereafter :-/!

Well, my point in that reddit thread still stands - as long as modesetting does not properly synchronize prime offloading with dri3.

Incidentally the last 6 commits to xf86-video-intel are because of my problems using prime offloading with dri3 for minetest and it is still not completely fixed.

Well, using UXA instead of SNA might be a quicker workaround...

Recently got rid of xf86-video-intel. No regrets

OMG. Totem is working again! Thanks!
