| rez_ | did you tried a stock debian on the reform? everything is working out of the box? | 00:08 |
|---|---|---|
| mntmn | rez_: what exactly do you mean by stock debian? | 00:10 |
| mntmn | rez_: the configuration and patches for the motherboard are not yet upstreamed, so debian does not have them, so the kernel is not from debian, for example. also there's a bug that etnaviv didn't fix yet, in conjunction with Xwayland, so i compile xserver from source with a little patch. | 00:11 |
| mntmn | rez_: it depends what you need. if you are ok with just using xorg on a framebuffer without 3d acceleration, you can use stock debian | 00:12 |
| mntmn | rez_: or if you want to use wayland without xwayland, that will also work on stock debian | 00:12 |
| mntmn | rez_: the goal is of course that all of this is upstreamed and in debian at some point. | 00:32 |
| banna | mntmn: very cool that it runs on the base debian system, however! | 00:35 |
| banna | I've heard some buzz about some BSD running on the reform, too. | 00:36 |
| mntmn | banna: yeah but so far i ran FreeBSD only in qemu-kvm, so still on a outer linux kernel | 00:36 |
| mntmn | i think freebsd doesn't have drivers for imx8mq yet, but i'm glad to be corrected | 00:37 |
| banna | Such a small percent would be interested in any BSD variant anyway, Linux is far better suited for a laptop | 00:40 |
| mntmn | banna: but still, i think at least openbsd would be nice to have | 00:42 |
| mntmn | hmm, traces of imx8mq in OpenBSD http://bxr.su/OpenBSD/sys/dev/fdt/imxgpc.c#62 | 00:44 |
| mntmn | hmm, a bunch of stuff is there already http://bxr.su/search?q=imx8mq&project=OpenBSD | 00:44 |
| banna | the project as I see it is a wonderful learning tool: I hope it gets adopted for curious minds as well as other applications | 00:44 |
| mntmn | banna: same, that's my hope too | 00:44 |
| khm | not me. I'm hoping for some good old-fashioned vendor lockin, where we have to buy a site license to unlock cpu cores. | 00:55 |
| banna | add in some unknown co-processors running immutable closed-source firmware, we have a deal | 00:56 |
| khm | now you're talking enterprise-grade! | 00:57 |
| mntmn | we could put in a ryzen embedded and you won't even get a datasheet... | 01:03 |
| banna | joking about it makes it sound more appealing lol | 01:26 |
| banna | (the open version, not the closed version) | 01:27 |
| mntmn | yeah i just looked at some ryzen embedded stuff and there really seems to be 0 publically available information on how the soc works | 01:28 |
| mntmn | even intel is more open, they have datasheets at least | 01:28 |
| mntmn | oh, i didn't even realize that Atom SoC was cancelled in 2016 | 01:33 |
| banna | that's crappy of AMD... but perhaps a bit sensible as all these embedded GPU-accel things | 01:38 |
| banna | like nvidia's jetson thing | 01:38 |

| rez_ | mntmn: thanks for the answers! yeah stock debian, I mean an ISO downloaded from their site :) | 02:59 |
| rez_ | ok, so there is still some part of the hardware not supported | 03:00 |
| rez_ | i usually use X and i3 as WM, but since I will want to code some 3d, I will probably need the GPU at some point :D | 03:01 |
| banna | rez_: the patches they apply to the base debian kernel will support the hardware fully! What he was saying is that it is not upstream yet, which is a slow process naturally | 03:19 |

| TheRealTachyon | I'm here | 23:04 |
| TheRealTachyon | I was wondering about the battery life because I'm still debating battery system design myself. The 12v display power is a bit of a monkey wrench. | 23:05 |
| TheRealTachyon | I was going to say. I'm typing on the system right now but purely on AC power. I have no DC system or battery system i place yet. | 23:06 |
| TheRealTachyon | But yeah, the reformed Reform looks pretty cool. | 23:14 |
| mntmn | TheRealTachyon: are you building that cluster laptop? | 23:15 |
| mntmn | TheRealTachyon: why is your display 12v, does it have it's own power supply? | 23:16 |
| TheRealTachyon | not a cluster no. Modular. | 23:16 |
| TheRealTachyon | the display is 12v because i used an off the shelf panel driver. | 23:17 |
| TheRealTachyon | which worked out because I wanted the display to be detachable and usable as a standalone monitor with multiple input options (HDMI, DVI, VGA) | 23:18 |
| TheRealTachyon | It's nothing close to Reform. It's me bodging together a lot of off the shelf parts for a one off personal project | 23:18 |
| TheRealTachyon | I'm still contemplating a sane way to do the power management and battery charging + BMS | 23:19 |
| mntmn | got it. what cpu/soc do you have in it? | 23:19 |
| TheRealTachyon | Right now I have a laptop brick PSU, 1 large (capacity) DC/DC converter and two small capacity DC/DC converters. | 23:20 |
| TheRealTachyon | that's the modular part. I started with a RasPi 4, but I intend to do other modules. Including an x86 module and maybe an FPG module. | 23:21 |
| TheRealTachyon | perhaps a DE-10 nano | 23:21 |
| TheRealTachyon | FPG = FPGA | 23:21 |
| TheRealTachyon | I like the Reform system board design. very nice. I'll have to go cruise the schematics and see what power system ideas I can borrow. ;') | 23:22 |
| TheRealTachyon | BTW, the ZZ9000 design is even more impressive IMO. The modularity and flexibility in particular. Nice work! | 23:23 |
| mntmn | TheRealTachyon: thank you! most of the work on the ZZ9000 is in the firmware, though ;) | 23:23 |
| TheRealTachyon | I take it you mean the FPGA programming? I don't doubt it.... | 23:25 |
| TheRealTachyon | but don't sell that board design short. Very well thought out and innovative. | 23:25 |
| TheRealTachyon | Sorry, haven't looked at the schematics yet, how does the trackball/buttons interface to the system? USB? GPIO? ? | 23:31 |
| banna | IIRC usb | 23:31 |
| TheRealTachyon | ok, that's handy. | 23:32 |
| banna | it's pretty diggable too as they are driven by an atmega32 which has a tonne of support | 23:33 |
| TheRealTachyon | That's the one thing I'd do personally is buy the kit and put in my own keyboard/controller. Use a ThinkPad keyboard because I like the KB, and the TrackPoint. If it's USB, I can use the Teensy controller I'm using for other projects | 23:33 |
| TheRealTachyon | banna, yeah, who doesn't have the Arduino dev kit installed? ;') | 23:34 |
| mntmn | TheRealTachyon: this might be helpful https://mntre.com/reform2-handbook/system.html | 23:34 |
| banna | excellent! hacking together commodity stuff is always a good thing | 23:34 |
| TheRealTachyon | ohh...nice resource. Thx mntmn | 23:35 |
| TheRealTachyon | Cirrus/Wolfson WM8960 Nice! | 23:38 |
| mntmn | :) | 23:38 |
| TheRealTachyon | Hmmm...didn't realize MIPI had that much performance capability. | 23:40 |
| TheRealTachyon | Hey, found the power section. Exactly what I was looking for. | 23:41 |
| TheRealTachyon | Those Ti buck modules, can they really handle 5A? Any idea what you're pulling from them? | 23:42 |
| + chartreuse (~chartreus@S0106f0f249dfd9c3.cg.shawcable.net) | 23:45 | |
| TheRealTachyon | PWM backlight, which means you can do refresh rate matching too. At least for full screen video playback | 23:47 |
| TheRealTachyon | mntmn, that resource page is great stuff!! thx!! | 23:48 |
