This largely copies the code from modesetting with minor adjustments. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- I've tried privately to get people to test this out, but to no avail. I don't have the hardware to verify this one way or the other. Ideally with this patch you should be (a) able to use a tiled monitor at 60hz with DP-MST and (b) be able to see connectors

This largely copies the code from modesetting with minor adjustments. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- I've tested this back and forth with a GTX 960 + 2x U2415 monitors, chained to each other. I turned them on/off. I messed with their DP 1.1/1.2 settings. I pulled plugs a few times. This seems to pass the test. No crashes, the connectors seem to come and go

Straight port of Matthias Hopf's KMS backlight code for xf86-video-intel, with reformatting and a couple of minor cleanups. Works fine on my MacBookAir2,1.

In multi-x-screen ZaphodHeads configurations, there isn't a one-to-one mapping of kernel provided drmmode crtc index to the index of the corresponding xf86Crtc inside the xf86CrtcConfig crtc array anymore, ie. for kernel provided drmmode->mode_res->crtcs[i], the i'th crtc won't correspond to the xf86Crtc in the i'th slot of the x-screens xf86CrtcConfig anymore, once

Ville also pointed out that I got a lot of the logic here wrong as well, whoops. While I don't think anyone's likely using 3D output with nouveau, the next patch will make nouveau_conn_mode_valid() make a lot less sense. So, let's just get rid of it and open-code it like before, while taking care to move the 3D frame packing calculations on the dot clock into the right place.

Keeping it in VRAM wastes CPU time, because cursor_set ioctl reads handed BO back to RAM, just to write it to actual cursor BO. Here (nv92/core i7), this patch decreases overall cpu usage of drmmode_load_cursor_argb from 4.6ms to ~90us and lets nv50_crtc_cursor_set disappear from perf traces. --- I considered accelerating kernel-side copying with GPU, but it turns out that: - it's slower

Just a backport of the two patches for v5.9 that you'll want to apply. The first one was Cc'd to stable, but I forgot to Cc the second one as well.

I don't understand this patch (what are all these masks? how are they used?), and don't want to invest the time required to do so. However Mario is probably the sole serious user of ZaphodHeads, and if it fixes issues for him, probably fixes issues for others who try and give up with ZaphodHeads. Any objections if I just push this out? On Sat, Jun 27, 2015 at 8:33 PM, Mario Kleiner

Next version of https://patchwork.freedesktop.org/series/49878/ . No changes, except that these patches are against master so hopefully intel's CI doesn't get confused this time.

Next version of https://patchwork.freedesktop.org/series/49877/ This fixes some rather silly bugs regarding DPMS On->Off changes failing for connectors which were just recently destroyed.

Hi all, I've frustrated myself the last few days yelling at our link training code. Comparing the i915 code to radeon and nouveau I've noticed the lack of a nice set of dp helper functions. So I've started to extract a few. There's lots more that we can do I think (link configuration selection, the i2c over aux retry stuff which diverges already between i915 and radeon, maybe
