17:38 <PabloPL> is here anyone familiar with powervr on exynos ?

17:46 <PabloPL> i got running on s5pv210 driver from 3.0.3 on 5.0.0-rc1 kernel, but need userspace libs for linux :/

17:46 <PabloPL> sgx540

18:19 <Wizzup> PabloPL: you forward porting the powervr driver?

18:20 <Wizzup> s/porting/ported/

18:20 <PabloPL> Wizzup: got it building and running under 5.0

18:20 <PabloPL> Wizzup: running = probing

18:20 <Wizzup> all my experience with powervr comes from omap and more specifically making it work on n900 with maemo leste

18:21 <Wizzup> but ti has various userspace drops that you might want to look at

18:21 <Wizzup> https://github.com/TexasInstruments/dri3wsegl this might also be relevant

18:21 <Wizzup> you'll still need closed userspace libs

18:21 <PabloPL> Wizzup: but i don't have userspace binaries for linux (only those from android), which would init it more

18:22 <PabloPL> Wizzup: I saw libraries from omap, but those were not for sgx540 :/

18:22 <PabloPL> Wizzup: Tried libhybris?

18:22 <Wizzup> not planning to use libhybris

18:23 <Wizzup> here are some notes on making it work on droid4 (which we haven't actually tried/done yet) https://leste.maemo.org/Motorola_Droid_4/PowerVR

18:23 <PabloPL> Wizzup: I wonder if using it, we could load libraries and binaries from android on linux (just for gpu) + driver "running" on mainline

18:23 <Wizzup> but it's also sgx540

18:24 <PabloPL> # cat /proc/pvr/version

18:24 <PabloPL> Version CustomerGoogle_Android_ogles1_ogles2_GPL sgxddk 18

18:24 <PabloPL> 1.8.GOOGLENEXUS.ED945322@2112805 (release) smdkc110_android

18:24 <PabloPL> System Version String: None

18:24 <PabloPL> currently

18:25 <PabloPL> but don't know if driver ever tried to talk to hw :(. will try to look at this more (just got it to build and probe without errors)

18:25 <Wizzup> ok, in #maemo-leste there are also people working with powervr driver, but for omap

18:26 <Wizzup> what device do you have that has powervr + exynos?

18:28 <PabloPL> Samsung Galaxy S (i9000), based on s5pv210 (one core, older than exynos4)

18:28 <Wizzup> interesting, what do plan to run on it?

18:29 <PabloPL> it's already running mainline kernel on it, with ubuntu 18.04

18:29 <PabloPL> i've created and submited device tree support for it

18:29 <Wizzup> if you're interested, check out maemo leste as possible mobile os for it :)

18:29 <Wizzup> cool!

18:29 <PabloPL> https://github.com/PabloPL/linux/wiki - more or less what is supported

18:30 <PabloPL> there is event uboot for it, which allows booting from sdcard/emmc/onenand

18:30 <Wizzup> really neat work.

18:30 <PabloPL> but without any acceleration for GUI (g2d or sgx), desktop is slow

18:31 <Wizzup> we're hitting the same thing with the motorola droid 4 phone

18:36 <LiquidAcid> anyone noticed this with kernel 4.20.y?

18:36 <LiquidAcid> [drm:drm_iommu_attach_device] *ERROR* Device 10800000.g2d lacks support for IOMMU

18:37 <LiquidAcid> might be related to 1feda5eb77fc279a4c4eb93b9a0ac3bf7254b57a
