bkeysmntmn: Are you still on track to open up the campaign the middle of this month?15:05
mntmnbkeys: unclear. situation is a bit chaotic15:06
mntmnbkeys: currently validating all final pcbs and parts15:20
mntmnbkeys: input devices are fine now. new motherboard will be brought up beginning of next week. if that works, we are ready to go15:21
mntmn(rev 3)15:21
bkeysThat is great news.15:22
* erlehmann_ -> erlehmann15:23
Jookiamntmn: new motherboard?15:23
mntmnJookia: yeah rev 3. has new boost/charge circuit, inrush limiter, realtime clock, new soundchip/amp15:31
mntmnmy order includes also 8 boards for beta testers.15:32
mntmn(people who pre-ordered beta units)15:32
Jookiamntmn: i have no idea how you can just make a new revision with all those changes at once and not be paranoid it's going to break15:32
mntmnJookia: no risc no fun15:33
Jookiatru that15:33
mntmnJookia: i consider these things mostly as necessary bug fixes15:33
Jookiathe novena had the same rtc issue iirc15:33
Jookiaor a simliar one15:33
mntmnbut yeah i tried to double, triple check everything15:34

marcodiegowill the reform offer any control (beyond pwm) of its keyboard backlight?21:36
marcodiegoI looked at the circuit and it looks like there are 8 controllable set of leds, right?21:37
bkeysWhat I would also like to know is if there is going to be any linux distros beyond debian that will be supported. I for one, would love to have support for Fedora21:38
marcodiegoarm ecosystem still looks like a bunch of very different computers in such a way that there are "generic" distros/images which run more than one single machine21:41
marcodiego*there are no21:41
bkeysYeah I noticed that, you would probably boot a regular Fedora distro but still use whatever kernel mntmn has prepared21:42
bkeysJust make sure the kernel binary is in the place u-boot is going to think it is in21:42
khmthe minute I get my hands on one of these things I'm gonna boot 9front on it and I look forward to the day21:48
swiveldoes 9front have any gpu acceleration support yet?21:53
khmno, but we don't have any software that would benefit from it, so it all works out.21:54
swivelthat's how chicken-egg situations work, I never wrote any 3d graphics programs in linux until most linux boxes had meaningful acceleration through mesa21:55
khmrunning a program on the same cpu your terminal has is a bit of an edge case in plan 9 to be honest21:56
khmI mean, we have quake and stuff, sure, but it's a distributed os and realtime rendering hasn't really been a priority21:57
swivelthere's so much processing power residingin GPUs these days it's quite unfortunate to have no utilization of it22:01
swiveland it would be interesting to see what a plan9 approach to those resources would look like22:01
swivelkhm: do you happen to know if the 2d compositing of the window system is at least accelerated these days?  high dpi screens are brutal to render on the cpu22:02
khmwe take measures in the VESA driver, like some write caching etc22:07
khmthere's nothing stopping people from implementing this, but it's just not been an issue mostly.  the main point of the various 'native' drivers is to address display modes that broken vesa implementations don't list22:10
mntmnmarcodiego: no control of LEDs, only brightness22:24
mntmnkhm: looking forward to 9front on reform!22:25
marcodiegomntmn, they are pwm controllable, right?22:29
mntmnmarcodiego: pwm duty cycle controls the brightness yes22:30
mntmnmarcodiego: i hooked this up to hyper + some f-keys now for testing, to inc/dec brightness22:30
marcodiegomntmn, https://files.mastodon.social/media_attachments/files/025/868/951/original/bcfe3cb449ccbbd8.png it seems there are pins controlling 8 sets of led. Aren't these sets individually controllable?22:31
mntmnmarcodiego: no, they are not.22:33
mntmnmarcodiego: also, the schematic has a mistake, it's missing 16 LEDs ;)22:34
mntmn(there are 80, not 64)22:34
mntmnmarcodiego: here is the datasheethttps://www.ti.com/lit/ds/symlink/tps61185.pdf22:34
mntmnmarcodiego: sorry, https://www.ti.com/lit/ds/symlink/tps61185.pdf22:34
marcodiegomntmn, thanks!22:35
