- Fixes https://github.com/termux/termux-packages/issues/26526 - Fixes https://github.com/termux/termux-packages/issues/25371 - All patches seemed to only need minor rebasing and no other errors - Tested working on Samsung Galaxy S9 SM-G960U with Adreno 630 - Add unofficial Adreno 710+720 support found here https://gitlab.freedesktop.org/mesa/mesa/-/issues/13036 and heredb9f6d0b31- After3294cad341, a new change is required in order to preserve GPU acceleration in the edge case of **EGL+Zink+Turnip+Termux:X11+Adreno 630**. I have named this change `0018-preserve-egl-support-in-zink.patch` and it is an original creation based on my ~2 years of experience developing EGL software for running inside Termux:X11 on Samsung Galaxy S9 SM-G96U with Adreno 630. **Unfortunately, I do not know what the effects of this patch will be on other devices that I do not have, so please tell me ASAP if it appears to break Zink on your device**. - After622612f67e, the default behavior of Zink is to enable the "general layout" mode whenever Turnip is detected. In testing in Termux:X11 on Samsung Galaxy A70 SM-A705FN, that change is incorrect and results in severe artifacts in Firefox when Firefox has `gfx.webrender.all=true` and `gfx.x11-egl.force-disabled=true` set in `about:config`, so `0019-disable-general-layout-in-zink-for-turnip.patch` must be created to forcibly stop Zink from enabling "general layout" mode when Turnip is detected.

mesa upstream code 'thinks' that if 'x11_dri3_open()'
|
|
has a negative retval, then DRI3 EGL acceleration in Zink with the current settings
|
|
is impossible in all cases and it disables Zink and falls back to software rendering.
|
|
|
|
However, Termux:X11 is a 3rd party edge case where, in actual testing,
|
|
for a very long time throughout the past year of mesa releases,
|
|
even if 'x11_dri3_open()' has a negative retval,
|
|
for some reason Zink+Tunip GPU acceleration still works if force-enabled
|
|
anytime that software rendering is not the initial default.
|
|
|
|
This 'Termux-unaware' upstream mesa codepath that fails to 'understand' the true
|
|
capabilities of Zink+Turnip+Termux:X11 has gradually been building up in the background
|
|
for the last several months, but in this commit:
|
|
https://gitlab.freedesktop.org/mesa/mesa/-/commit/3294cad34159bd5317e3dfb0cb4e0ba5caca9f77
|
|
the 'switch was flipped' to the new codepath, so to speak, locking vanilla mesa's EGL
|
|
support away from the Zink+Turnip+Termux:X11 codepath unless some kind of intervention
|
|
is performed, such as this patch.
