Potential new mali driver
by Bill Kontos 08 Jul '17

08 Jul '17

I just spotted this https://people.freedesktop.org/~cbrill/dri-log/?channel=lima&date=2017-06-23 It seems like there is a new person working on a driver for mali hardware, specifically the mali-400, and apparently it is an amd employee.

thoughts, for the future or a late future,
by zap 28 Jun '17

but I think whenever you decide to make a new eoma68 laptop design, make it a 13 inch instead of 11 inch. aka, more space, means more durability heat-wise... This would be even more effective whenever you start making your own processors probably because then it wouldn't need to be as low This is one idea I just wanted to throw at ya, but another idea came to me, its just an idea of course, but a libertybsd based router would be ultra secure I bet. if it is possible I mean. ;) Libertybsd = openbsd without blobs ps, if you decide to make a processor from lowrisc, will it have 3d acceleration/support for the latest opengl? Those are my thoughts for now. Tell me what you think.

Hi, I told someone about EOMA68. When they Google searched for “modular laptop“ in German, they got this: http://pangeaelectronics.com/EN/index.html I don’t know what you think of that or if they would care about EOMA. To me the Web site looks more like they are interested in vendor lock-in, but who knows. Regards, Florian

3D Printering Idea
by Christopher Havel 26 Jun '17

26 Jun '17

Hey, Luke, is this article at all useful to you? http://hackaday.com/2017/06/24/hackaday-prize-entry-a-3d-printer-management… It looks like something you could fairly easily implement in such a way as to potentially speed up laptop part printing... the way I envision it, you have one printer for each part, and it just spits out one after another into, eg, an empty Tide or Fresh Step box. ...or maybe I'm daydreaming. You tell me :)

FPGA video decoder

Hello, Some time ago Luke et al was discussing using an FPGA to decode video but thought it too expensive. Well, not that this changes anything, but I found this little beauty wile looking at something else: https://alphamaxmedia.com/w/index.php?title=NeTV2 Sincerely, David

Hi, to pick up this discussion again, Parabola has concluded that we will for the time being need only one preview card, and I will privately pay for it in full. following are the contact information for the hacker in question: Andreas Grapentin (me) <andreas(a)grapentin.org> Potsdam, Germany I can provide a complete address through a more private channel :) Best, Andreas -- ------------------------------------------------------------------------------ my GPG Public Key: https://files.grapentin.org/.gpg/public.key ------------------------------------------------------------------------------

If ARM is still as openly hostile as they appear to be towards reverse engineering of their GPU designs, I don't think that pursuing lima development is a very good option. I suspect that if development of the driver resumes, they will probably continue their horrible crusade against Luc and I don't want to see that happen to anybody. I think that if we are really trying to play the long game here, then that money would be better spent working towards the development of an open GPU design that we can can use in future risc-v SOCs. Perhaps another option that might be more amenable and rewarding for Luc. Would be to open a monthly patron-styled donation page not to develop lima drivers, but instead to work together with people like Jeff Bush (the main guy developming the Nyuzi GPGPU: https://github.com/jbush001/NyuziProcessor ). To me (and I haven't read into it much) it seems like, the focus thus far for the Nyuzi project is only on developing the GPGPU and not so much looking at it from the point of view of, how would we write a Linux driver for this device. I think if we focused some money on Luc (driver developer) and the Nyuzi (hardware developer) developers, then they might be more inspired to focus their efforts on producing a quality GPGPU and supporting drivers. Honestly, I think that working together with people who are openly developing a GPU design and who would probably be quite welcoming of assistance from Luc would be a much better situation for him than if he went back to trying to working on the lima driver. Perhaps a company like si-five ( https://www.sifive.com/ ) or the risc-v organization might even consider trying to sponsor a collaboration like this as having a good open GPU implementation would certainly be a boon to them in the future. Anyhow, that is my two cents. -Mike

Incidentally, couldn't you do this in an mostly automated fashion? I mean: 1. Have computer program send bits to GPU 2. Have same program read bits from EDP (or whatever), to determine result and time spend on task. 4. Have another program create a spread sheet for the in-out-time info and stats. 3.

I'm assuming that beings that there are so many Mali GPUs and hacker boards out there that other people would also be very interested in this. What would I need to know to do this? Quick, point me to the books! No, really, I would do such a thing, I don't have a lot to loose, though for free I'd be taking my time... But still, I'd need an education. Thanks, David

EOMA68-A20 2.7.4 pre-production prototypes received and working
by Luke Kenneth Casson Leighton 23 Jun '17

23 Jun '17

i received the latest pre-production cards yesterday and have tested one of them: it works. however (and this is the whole point of doing pre-production prototypes) in endeavouring to use automated assembly and solder paste it was discovered that the VIAs underneath the pads for the JAE DC3 Micro-HDMI connector are sucking the solder paste in and down, leaving the pins not properly connected. the factory's engineer hand-soldered the 10 samples, but we cannot possibly do 1,000 PCBs by hand.... so it is necessary to do some test PCBs to work out how to get these connectors, with utterly tiny pins (0.25mm wide) to stick, given that the tracks simply have to come up from underneath using VIAs. VIAs coming up on a pad is generally bad because it's a hole down which the solder paste simply... sucks down. if anyone knows any tricks i would appreciate hearing them. i was thinking of creating the pad with a triangular end, placing the VIA right at the end so that the solder paste can't "wick away". anyone got any other ideas? l. --- crowd-funded eco-conscious hardware: https://www.crowdsupply.com/eoma68
