| zzarr | alf_ how much work is it to make Mir talk to fbdev? | 14:26 |
|---|---|---|
| anpok_ | zzarr: is that really the right problem to solve? | 14:32 |
| anpok_ | i mean .. if you have a drm capable kernel driver.. you already have the right mechanism to efficiently post to screen, and to pass buffers from clients to server | 14:33 |
| anpok_ | the only missing piece in your case seems to be a mali driver that works with drm | 14:34 |
| anpok_ | or as a temporary solution kms-swrast | 14:34 |
| anpok_ | oh of course your drm kernel driver could mis some features | 14:34 |
| anpok_ | then we would have to add those.. what mir needs there can be easily enabled via various drm-helpers.. | 14:35 |
| anpok_ | zzarr: you could ask the lima driver developers.. | 14:36 |

| * alan_g thinks it really is about time we cleaned up support for 3rd party "platform" modules | 14:36 | |
| anpok_ | zzarr: i did look at that situation with mali recently | 14:37 |
| === dandrader_ is now known as dandrader|lunch | ||
| anpok_ | zzarr: the mali drivers user ump to manage memory... in theory ump is capable to grant other processes access to buffers. But I havent seen any way to get egl/glev2 render to such a handle, their fbdev-egl drivers do not over an entry point with a native ump handle to render to.. | 14:42 |
| anpok_ | the x11-egl drivers require an x11 connection, and also allocation happens underneath.. | 14:43 |
| anpok_ | so the only arm-mali solution that might work - is the android drivers.. | 14:43 |
| anpok_ | s/not over/not offer/ | 14:44 |
| anpok_ | so if you can build an android kernel for your board.. you should be able to get mir working with hybris and the arm drivers that you can download from arm.com.. | 14:45 |
| anpok_ | the only other options are: build and select kms-swrast as dri driver, or look into lima.. http://limadriver.org/ | 14:47 |
| zzarr | okey anpok_ | 14:50 |
| zzarr | what changes needs to be done to the kernel to run hybris? | 14:51 |
| zzarr | anpok_, or is there a tutorial how to rewrite the X driver to become a Mir one? | 14:55 |
| zzarr | anpok_, is there a Mir driver I can have a look at (so I can compare the mali X driver to it?) | 14:57 |
| zzarr | I'll read this later, I'll leave the chat open, have to go | 14:58 |
| anpok_ | zzarr: hm not sure what hybris actually needs.. but the mali driver for android will require a mali kernel module.. I am not sure how to integrate that one. I once looked how it was done for an Allwinner SOC, and it didnt look easy.. | 14:58 |
| zzarr | anpok_, okey, you don't think it's possible to "just install" the user space driver? | 15:01 |
| anpok_ | as in I tried to migrate that one to a newer kernel version, and got lost in the integration code that needs to access clocks and interrupts | 15:01 |
| zzarr | ohh.... I see | 15:01 |
| anpok_ | so the easier path here would be to get an android kernel for rockchip | 15:01 |
| anpok_ | and port ubuntu-touch to it | 15:01 |
| anpok_ | but I cannot help with that | 15:02 |
| zzarr | I thought it was a matter of kernel configuration | 15:02 |
| anpok_ | well .. of configuring the right kernel | 15:02 |
| zzarr | the thing is, everything except the graphics and closing the lid/flipping are working | 15:03 |
| anpok_ | someone did that for rk2918 http://forum.xda-developers.com/showthread.php?t=2318728 | 15:05 |
| zzarr | I have seen that there are android specific configuration options in the kernel, but... I'll have a look | 15:05 |
| zzarr | If I manage to make an Android version of the kernel (or get one from some RK3288 based device) will the other drivers (/lib/modules... /lib/firmware...) stop working so I need a WiFi driver and so forth too? | 15:09 |
| anpok_ | which kernel did you use? | 15:13 |
| zzarr | I used one for Kali linux for my device | 15:14 |
| zzarr | (it actually uses both KERN-A and KERN-B) | 15:15 |
| anpok_ | so .. you would need one that has drivers/gpu/mali | 15:15 |
| zzarr | anpok_, the kernel(s) are basically the default one(s) but with console activated | 15:16 |
| zzarr | and as it have GPU acceleration when Chrome OS is booted it have some driver | 15:17 |
| zzarr | but it's drm | 15:17 |
| zzarr | anpok_, I hope that I'm not too tiresome, but as many devices are based on the RK3288 SoC I think it would be very nice to get Mir support for it :-) | 15:21 |
| anpok_ | hm yeah it would be interesting to see how the mali driver that they probably use interact with the drm module | 15:22 |
| anpok_ | chrome os has the advantage that they only have a single rendering process in the system, and the different browser rendering process communicate the command streams to that process.. | 15:23 |
| zzarr | anpok_, yea, but I think that's only the user space driver | 15:24 |
| zzarr | and freon | 15:24 |
| zzarr | I'll download the code for the mali X driver | 15:25 |
| anpok_ | oh the x11 user space parts are open source? | 15:25 |
| zzarr | I think they are, if I don't remember wrong | 15:27 |
| zzarr | here http://malideveloper.arm.com/resources/drivers/open-source-mali-gpus-ump-user-space-drivers-source-code-2/ | 15:28 |

| zzarr | I have to go now, I'll check the chat later (I'll leave it open) | 15:30 |
| zzarr | thanks so much anpok_ | 15:30 |
| zzarr | I'll figure it out some how ;-) | 15:30 |
| anpok_ | ok | 15:30 |
| zzarr | anpok_, now I'm here again for a little while | 16:12 |
| zzarr | I'm sitting on a bus | 16:12 |
| zzarr | I'm remote controlling a computer at home with the chat | 16:13 |
| zzarr | anpok_, I got the ump driver, is that enough to write a Mir driver? (I don't see anything interesting yet) | 16:20 |
| zzarr | I'm soon to get off the bus | 16:22 |
| anpok_ | enough to write a server i guess. but not enough to get a client to render with glesv2 as far as i understood it | 16:22 |
| zzarr | are you looking at the code? | 16:23 |
| anpok_ | i was looking at the glesv2 sdk examples from arm ... looking for a way to initialize egl with an ump handle.. | 16:24 |
| anpok_ | but maybe i was missing something | 16:24 |
| zzarr | I have to close the connecton now | 16:24 |
| zzarr | okey | 16:24 |
| zzarr | bbl | 16:24 |
| zzarr | I'm back... for now, I was going to a postal office, but the guy who tried to deliver the package to my door wrote the wrong office on the paper he put in my mailbox | 17:09 |
| zzarr | so I have to go to another office.... | 17:09 |
| zzarr | anpok_, the code I downloaded have a ump_arch.c, ump_frontend.c and ump_ref_drv.c are they useful? | 17:12 |
| zzarr | anpok_, there are other ump* files as well | 17:12 |
| zzarr | I have to go to the other postal office now | 17:13 |
| zzarr | bbl (again) | 17:14 |
