12:31 <geecko> xplodwild, reading s3cfb_ops.c again and again, i still have no clue how it even works on the s3

12:31 <geecko> xplodwild, also got this as reference: http://git.insignal.co.kr/insignal/origen_quad-jb_mr1.1/kernel/tree/drivers/video/s3c-fb.c?h=origen_quad-jb_mr1.1

12:31 <xplodwild> geecko: I'll get you a log tonight

12:31 <geecko> xplodwild, https://github.com/omnirom/android_kernel_samsung_smdk4412/blob/android-4.4/drivers/video/samsung/s3cfb_ops.c#L1768

12:31 <geecko> i'll need the values for phys_addr and virt_addr

12:32 <geecko> xplodwild, it is _never_ set anywhere in s3cfb, and hwcomposer should take care of that, but the insignal one doesn't

12:33 <geecko> xplodwild, so it's undefined, so it should crash the same way for all devices :o

12:33 <geecko> xplodwild, btw, phys_addr and virt_addr were added in s3c-fb.h by codeworkx to match our kernel

12:39 <geecko> xplodwild, there's also this https://github.com/omnirom/android_kernel_samsung_manta/blob/android-4.4/drivers/video/s3c-fb.c

12:40 <geecko> xplodwild, it seems that the framebuffer addresses are got from ion

12:40 evcz has joined #teamhacksung

12:40 <geecko> no clue about how it works, but it should interesting to try to implement it properly, as we don't know how to get proper values for virt_addr

12:41 <geecko> everything is done into the kernal for insignal and manta sources

21:15 <geecko> xplodwild, it's funny how s3cfb from insignal is 100% different from the samsung mobile one

21:15 krabador has joined #teamhacksung

21:30 paulk-collins has quit [Remote host closed the connection]

21:34 <geecko> xplodwild, i'm not sure if replacing the current s3cfb with the new one would work :/ it couldn't manage the screen

21:35 <xplodwild> no idea

21:37 <geecko> xplodwild, i'll try :3

21:40 <geecko> xplodwild, well, it seems that display management and frambuffer management are split properly, maybe it will work, if i replace the right files :D

21:40 <geecko> but first i need to eat ;D

21:43 <xplodwild> geecko: the oven is heating here :P
