How to use Mesa3d's Iris instead of i965

[İlhan Atahan]

Hi, i am trying to get GALLIUM_HUD works, but i unsuccesfull on it, i guess it is not uses Intel Iris driver.
GALLIUM_HUD works well with Linux Mint on my system.

Here is my cpu/kernel/mesa info:

Intel(R) Core(TM) i5-10210U CPU
Kernel 5.10.26(in android x86)
Mesa 20.3.5(in android x86)

Kernel 5.4.0(Linux Mint)
Mesa 20.2.6(linux Mint)

I am simply edited init.rc file(found as attachment).
But it not worked, i also used "kill -10 xxxx" to restart surfaceflinger.
I hope get a solution on this topic :-)

Hello, 

in order to use iris instead of i965, as per the thread subject,

you could either compile mesa with the following changes

https://cgit.freedesktop.org/mesa/mesa/commit/?id=f8e5f945b8f936b81526ed0e49b66cda6ddb8466

or, as an alternative, change init.x86.rc in a write enabled installation in the following way, save it and reboot,

but mesa 20.1 or later is required - NOTE: I have not tested this way

diff --git a/init.x86.rc b/init.x86.rc

index b36a722..fa9d8e8 100644

--- a/init.x86.rc

+++ b/init.x86.rc

@@ -8,5 +8,5 @@ on early-init

     export force_s3tc_enable true

     export EGL_LOG_LEVEL info

-#   export EGL_DRIVERS egl_dri2

+    export MESA_LOADER_DRIVER_OVERRIDE iris

 

You need to be aware that the only visible difference between i965 aka 'classic driver' and iris aka 'gallium driver' visible in android-x86 is in the Settings,

in the GL renderer i965 classic driver has 'DRI', while iris gallium driver does not have it.

In order to enable GALLIUM_HUD there is a thread in this forum, please search 'GALLIUM_HUD' without quotes

Cheers

Mauro

Thanks you, i tried editing init.rc and it is worked :-) , but somehow i saw multiple GALLIUM_HUD overlays at the same time.

Hey, it was due to i set "xport GALLIUM_HUD_VISIBLE true" instead of false, it works normally when i set it false and restart surface flinger, thanks you again :-)

iris can work with gralloc.drm? needn't hwcomposer.intel and gralloc.intel or gralloc.minigbm?

[Huy Minh Bui]

Yes we are still using gralloc.drm . But according to ilhan himself and some users with 11th Gen CPU reported, there are a lot of app crashing and people can't use it now.

by the way can you show me how to compile gralloc.minigbm, gralloc.intel and hwcomposer.intel on nougat-x86 again ? The last time I tried I got black screen on my Intel HD Graphic 2000

kabylake gen9.5 can work with iris on android? i test not work.

i965 driver is used for KBL/CML, iris driver is used for TGL.

For now, glxinfo using iris_dri.so should show:

OpenGL vendor string: Mesa Project

OpenGL renderer string: HD Graphics 630 (Kaby Lake GT2)

while glxinfo using i965_dri.so should show:

OpenGL vendor string: Intel Open Source Technology Center

OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 630 (Kaby Lake GT2)

my 2560x1600 screen hdmi1 connect amd3400g vega11, hdmi2 connect intel7820hk, they not blackscreen used hwcomposer.minigbm and gralloc.minigbm. my hwc and minigbm can found on my github.

i only want to test if use iris, 32bit chrome will crash or not on intel gpu? 

i use 32bit chrome 71.0.3578.99 on amdgpu.

i open a chrome bug. https://bugs.chromium.org/p/chromium/issues/detail?id=1192909

[Huy Minh Bui]

That is the same crash that I have when I use amdgpu back then, 32bit Chrome (or Webview) crash. I tested old version like 60 or latest one like 81 or more and it didn't work. Sadly my GPU broke now

Also on nougat-x86, iris can't even open browsers

But why use nougat x86? There are many issues with it, for me.

[İlhan Atahan]

Firefox works for me with intel iris.

Even chrome opens for me, i think thats because 11th gen hardware are unstable.

[Huy Minh Bui]

Hey youling, can you compile and test iris now ?
But this time, cherry-pick these 2 commits 

https://github.com/projectceladon/external-mesa/commit/8c72d5c60f22b7376e5a757dec09b9c1f0e4bd2d

https://github.com/projectceladon/external-mesa/commit/6c091cf623d14e35eceaa079e8965bcca4ec294b

and then test

the new crocus driver crashed just like iris so I made 2 exact same commit for crocus

https://github.com/hmtheboy154/mesa/commit/2f6422e627222da9fdc2da1da2c46a3d1ae20770

https://github.com/hmtheboy154/mesa/commit/0654e55f0899f0dd41b76021c35b7c8af32e1ffe

I compile and it's running fine now, not a single crash anymore so far. (Only low performance due to the fact that I use Sandy Bridge CPU)

Here as you can see, crocus can run, even with drm_gralloc (gralloc0)

nice! test "INTERNAL: Fix iris driver crash on 32 bit system""INTERNAL: Remove performance info query resulting in CFI kernel panic", iris can work on 32bit cm14.1, 32bit chrome also can work, no different feel between i965 and Iris, only different is gl vendor.

[Huy Minh Bui]

Let's goooooo, now we got both crocus and iris running :DDDDD

export MESA_LOADER_DRIVER_OVERRIDE crocus

I test crocus can work on Baytrail gen7 gpu, not used "HACK: loader: enable crocus by removing i965 and iris in driver_map[]".

Well yea you can export it like that, it just I'm too lazy editing init :p

Update : Mesa3d has officially made a prefer loader for crocus, so I can now revert "HACK: loader: enable crocus by removing i965 and iris in driver_map[]".

youling might already know this too. So we can kinda ditch i965 completely in the future when crocus got stabilized.

with this patch https://gitlab.freedesktop.org/mesa/mesa/-/commit/f94c79674105afe08da0e60f937e62b0035d72d7 , iris and crocus can both work.
