mesa, glmark2, vkmark, alsa-lib

[askorbinovaya-kislota]

turnip works with the termux-wsi patch, but shutters a lot (same with zink on turnip), MESA_VK_WSI_DEBUG=sw "fixes" all shutters

i also tried building the new 23.3.0-rc5 mesa, it needs an updated no-hardlinks patch and disabling the lua subproject (or packaging lua to gpkg), ping me when 23.3.0 is released

created the opengl metapackage like in bionic termux, but i think it would be better to just depend on libglvnd...

alsa-lib is packaged because some packages and programs (in box64) hard-depend on it, even if it is not usable on android

this PR closes #137 and #141

At the moment I can’t correct errors in your pr because I’m busy, and I also have another pr (#161). Therefore, I ask you to correct your mistakes yourself.

[askorbinovaya-kislota]

all errors are fixed now:rocket:

[Maxython]

It was in vain that patches were added that correct compilation on arm due to wayland-scanner, since this is a global error.

[askorbinovaya-kislota]

i thought that it was qemu-arm issue... any ideas how to fix it?

[Maxython]

most likely just need to recompile libicu

@askorbinovaya-kislota, I managed to run zink:

I'll merge your PR soon, but before that I want to update libllvm-glibc.

[askorbinovaya-kislota]

i found that osmesa-glibc package is empty and not every libOSMesa.so file/symlink was included, libOSMesa.so.8.0.0 is a part of mesa-glibc while it should be in osmesa-glibc

to avoid merge conflicts, i'm sending this small patch here:

the patch

 TERMUX_SUBPKG_DESCRIPTION="Mesa Off-screen Rendering Library"

i did not check if osmesa-glibc package is correct with the latest changes and didn't try building with this patch applied because i have troubles accessing my main PC, but this should be fixed before merge

How to force mesa-glibc to use gpu:

• Use zink driver
  To enable the zink driver you must simply enter the following value before running a program: MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink. Please note that not all gpus support the zink driver (for example: if you have a Qualcomm gpu, then it supports zink; if you have a mali gpu, then it does not support zink). To make sure your gpu supports zink, check for the existence of /dev/kgsl-3d0. Tip: if you have a Samsung device, then you can enable "GPUWatch" from "Developer options" to speed up the gpu, but then the cpu will be slower.
• Use virgl driver (recommended for mali gpu)
  To enable the virgl driver you must install the virglrenderer-android package, run the virgl_test_server_android command in a separate termux session, then you must add the value GALLIUM_DRIVER=virpipe before running a program. Note: on mali gpu, vulkan with termux-x11 will not render images for some unknown reason (if you use vncserver, it will work but much slower).

The note: In theory, mesa should use the panfrost or lima driver to directly access the gpu mali, but for some unknown reason this does not happen. It is also possible that due to the fact that mesa does not use these drivers, vulkan does not work correctly in termux-x11. I need to look into this issue more.
