How to upgrade mesa in android-x86 branch ?

[Lovereighty Lau]

I have built android-x86 marshmallow but found blank display problem when running a PoC Unity3d inside vmware (same program runs fine in android-x86 with a low-end PC).  I see the mesa version of the branch is not latest, so I download from mesa the latest version, but obviously it cannot be simply merged into android-x86. (I have tried but too many fails) 
So I would like to ask : Is there a standard way to merge mesa source into android-x86 branch ?  On the other hand, can I merge the mesa part (external/mesa and kernel ? ) from newer branch (e.g. Oreo) into Marshmallow ? Thanks in advance.

Hi,
It is possible, but easier in newer Android stable version,
please have a look at following link to build nougat-x86,
or download esperimental iso

Instructions File: build_with_drm_composer.txt It helps to overcome build errore

Hi Mauro,

Thanks for the info, particularly the instruction file stating what files are to be replaced.  Since the latest mesa version is 17.3.3 whereas it is 17.1.10 in x86-Nougat  (which has the same problem as in Marshmallow), I think I should try the new mesa.

when i run this command:

cd ~/nougat-x86_development/external/libdrm/
git remote add maurossi https://github.com/maurossi/libdrm
git fetch maurossi 2.4.89_android-x86
git checkout FETCH_HEAD

It asks user name and password from github. Then i add my username and pass. but it fails. How can I fix this issue? other command run fine. I m building android-x86 N.

There was a type on that command, the repo has a different name, but I wrote it wrong

git remote add maurossi https://github.com/maurossi/drm

@Mauro Rossi

Which branch mesa, kernel your recommend to build with nougat-x86?

I built with both mesa 17.3.3_oreo-x86/17.4.0devel_swrast_w52, drm 2.4.89_android-x86, drm_hwcomposer, llvm60, device_generic_common nougat-x86_kernel-4.15 and kernel-4.15. I changed as you said  external/mesa/Android.mk (to libLLVM60, iHAVE_LLVM variable accordingly set to 0x0600 ). Build successfully, it stucks at Android-x86 booting screen.

Please guide me.

With mesa 17.3 and later used in nougat-x86 build, you'll need to checkout x86 oreo-x86 branch for project external/drm_gralloc

Please provide your system specs
