dottedmag, I was hoping to find a ready-made library for that - one that does not magically attempt to replace libc functions with something else, but something we'd use explicitly so it's obvious. No way I'll sign up to maintain such myself.
<dottedmag>
pq: "Drop a file from OpenBSD once in a while" wasn't a maintenance burden as far as I can remember.
<pq>
Unexpected with a HDR monitor yet once you think of it, it kinda <facepalm>: moving the mouse cursor around causes visible changes in what is probably backlight zones.
<pq>
I hope I'm just driving it wrong.
<pq>
...also because I expected to be blinded but I wasn't.
<pq>
I rarely am, I have your KMS doc patches in queue :-) Ah, HDR metadata printing.
<emersion>
ahah :P
<pq>
what's it missing, review? or someone taking over the dev?
<emersion>
someone addressing the review comments

aha, we'll see. I haven't dug into any other field than the eotf yet.

emersion, unfortunately, libdrm does not #define the constants used in the struct. They come from CTA-861-G spec. Maybe that should be fixed in libdrm... which means in the kernel. Ugh.
<emersion>
yeah, iirc it was mentionned at some point with danvet or vsyrjala…
<pq>
I'm somewhat surprised the hdr_output_metadata was even accepted in UAPI headers
<pq>
as is
<danvet>
we have a pretty good track record of occasionally screwing up big time
<pq>
eh heh
<MrCooper>
pq: if that's moving the cursor over a black background, sounds expected: It can't turn off the backlight tile where the cursor is located
<pq>
well, this one is mostly cosmetic at least
<pq>
MrCooper, the background is the default weston "flower" wallpaper, so not quite black. But also the whites are not as bright as I'd expect.
<pq>
I still have more knobs to try, so fingers crossed I will see the light. X-)
<daniels>
isn't seeing the light the exact problem you're having ... ?
<pq>
I'm picky
<pq>
it's not the light I was looking for
<daniels>
pscht :P
<kennylevinsen>
I imagine reducing the brightness of your cursor (mapping the plane to SDR range?) is the only fix
<pq>
possibly
<pq>
it seems to me mostly light leaking at the bottom edge though, I don't see it anywhere else.
<kennylevinsen>
But then what is the point of a HDR monitor if not to have a 1600 nit cursor?
<pq>
*to be
<pq>
600 nits only ;-)
<pq>
...if I had the mode right
<kennylevinsen>
Bottom edge of cursor or screen bezel?
<pq>
screen bezel
<kennylevinsen>
Sounds like it's backlight bleed from an edge-lit monitor doing local dimming
<kennylevinsen>
Try a black image in sdr mode at full brightness, helps identify bleed - if it's mild there isn't much to do, but if it's really bad it could be a defect
<pq>
it's HP Pavilion 27 QD (quantum dot)
<pq>
if it starts bothering, then maybe - so far I'm just abusing it
<pq>
it also needs a power cycle if the computer reboots while it's "off" :-P
<pq>
or maybe it was if it is plugged to mains while video cable is connected but not transmitting... not sure

pq: vulkan has a knob to turn off local dimming so there at least sometimes is such a knob somewhere

just shifted from X11 to Wayland \o/
<daniels>
nice :)
<raghavgururajan>
Btw, would it be better if wlroots is merged into wayland umbrella as wayland-roots?
<bl4ckb0ne>
why?
<kennylevinsen>
It would just change a name
<daniels>
it's one of many frameworks, all with different designs, philosophies, and tradeoffs

I meant like maintaing it under the wayland project. wayland, wayland-protocols, wayland-roots.
<bl4ckb0ne>
what about weston
<raghavgururajan>
IIUC, weston is an implementation of wayland compositor. wl-roots/wayland-roots is/will-be a kit that is used for making wayland compositors.
<raghavgururajan>
Also, weston happen to provide reusable libraries.
<daniels>
weston is only really in there for historical reasons
<raghavgururajan>
I see.
onelegend has joined #wayland
<raghavgururajan>
In my opinion, it would be reasonable if the wayland project provides/distributes toolkit to build wayland compositors, which can be wlroots.
<whot>
emersion: Jose Exposito has taken the MR over, I think he's going to finish it
<daniels>
raghavgururajan: there’s no one-size-fits-all. every one of the available options have their own tradeoffs, and also significant philosophical differences. it would be like saying that the W3C recommend Apache/Chromium over nginx/Firefox.

I understand drmGetMagic/drmAuthMagic is completely obsolete, but how is it used to work? Who obtained the magic and passed to whom to authenticate?
