support for Ubuntu 16.04 kernel 4.x? #16

Open gastonnina opened 6 years ago

gastonnina commented 6 years ago

Hi people,

please update this for the next LTS Ubuntu 16.04 and in future 18.04

Cinerar commented 6 years ago

There is user on reddit who is ready to write driver if he will be sponsored with devices https://www.reddit.com/r/linux/comments/7165gs/fresco_logic_just_dropped_an_open_source_linux/

FrescoLogic? @fresco-fl2000 Cmon.

fresco-fl2000 commented 6 years ago

Hi Cinerar, I've brought up the "free sample device" issue to the Fresco management team. Hopefully the management team would setup "FL2000 driver sponsoring" program. After all, the sample device is cheap, and I don't think it would cost too much to sponsor with free sample devices.

@gastonnina Hi you could try my testing branches on https://github.com/ulli-kroll/FL2000/tree/testing-v1 https://github.com/ulli-kroll/FL2000/tree/testing-v2 but please be are there is NO DRM support here

phaltness commented 6 years ago

Hi, @ulli-kroll, i was playing with testing-v* branches, but - nothing seen at my hdmi display - no one pictures or desktop video stream. nothing (((. probably it was missed something. if you wish, i could provide my logs to be helpful.

ulli-kroll commented 6 years ago

As I said no DRM DRM -> Direct Render Manager as "service" with you can talk to the graphics hardware via various user space programs. I have a DRM framework on my side, but as mentioned here sometimes my big problem is memory. Maybe I do code some hack here

phaltness commented 6 years ago

@ulli-kroll, could you please provide your methods of DRM usage - maybe as simple "how-to" - ill try to help with testing-v* branches.

CanNuhlar commented 6 years ago

@ulli-kroll Yeah would love to see the source code of your DRM work.

prusswan commented 6 years ago

@fresco-fl2000 It shouldn't be very hard to ship one from your TW/CN factories..

Also, I have one such device and can possibly connect it to VMware as part of a remote testing setup. However, I don't know how feasible it is for a remote user to access the display output without an actual monitor.

fresco-fl2000 commented 6 years ago

Hi prusswan, and those who are interested in getting FL2000 device samples, I am not in position to make any promise. I would suggest you to go through Fresco Logic Sales team or marketing team (sales@frescologic.com , marketing@frescologic.com ).

Some update, for those who can understand. I have currently (barely) no time, busy at my main job

You need DMA CMA No HDMI, because the I2C device is crazy and of course no actual screen

fresco-fl2000 commented 6 years ago

For those who are interested in free samples:

I got instructions from management team that we don't have sample adapters for give-away. FrescoLogic only sells chip IC, instead of adapters.

prusswan commented 6 years ago

@fresco-fl2000 then get one from your downstream clients, or write the drivers yourself..

davidhscope commented 6 years ago

Dear,

I had bought a device with fl2000 buy, i use ubuntu18.04 and i can't get display running. Please help me!!!

CanNuhlar commented 6 years ago

It's because there is no drm support yet. From a user's point of view you may say it's unsupported at the moment.

Hello everyone, can you send me a link with the adapter to buy? USB to VGA to use on ubuntu 20.04(displaylink chipset). I found this one "https://pt.aliexpress.com/item/33022768893.html?spm=a2g0o.cart.0.0.3a6f3c00uPCK99&mp=1", but I don't know it's the best choice.
