News about Panfrost Arm Mali Graphics Driver and OpenGL

Quoting an old 2019 locked topic, viewtopic.php?f=8&t=13574


... I am absolutely surprised that a search in the forums for the term "panfrost" turns up ZERO results.

For those of you who don't know what Panfrost is, it is an open source driver for the Mali Midgard (and bifrost) GPU chipsets that was recently merged into the upstream mesa codebase.



But in June 2021,

[Panfrost Gallium3D Driver For Open-Source Arm Mali Graphics Now Has OpenGL ES 3.1 - Phoronix](https://www.phoronix.com/scan.php?page= ... nGL-ES-3.1)

...Arm's Midgard 2nd Gen taps out at OpenGL ES 3.1 while Midgard 3rd/4th Gen and Bifrost are ultimately capable of OpenGL ES 3.2 once this open-source driver support has been wired up....


This is very interesting news, for those of us, who insist on using Arch Linux ARM with a lot of perfectly capable old hardware like chromebooks etc.

This isn't Archlinux ARM, it's Debian, but still it's relevant news:

[Debian 11 "BullsEye" released with Panfrost & Lima GPU drivers, exFAT support, driverless printing - CNX Software](https://www.cnx-software.com/2021/08/15 ... s-printing)


Debian 11 now comes with Mesa 20.3 framework which includes Panfrost and Lima open-source Mali GPU drivers by default, as well as the Vulkan 1.0 conformant V3DV driver for Raspberry Pi 4.

As noted in the documentation that means the following Arm Mali GPUs are supported:

Mali 400 and 450 GPUs via the Lima driver
Mali T720 (only up to OpenGL 2.1 and OpenGL ES 2.0), Mali T760, Mali T820, Mali T860, Mali G72, Mali G31, and Mali G52 via the Panfrost driver
Experimental support for T604, T620, T830, T880, G71, G51, G76

In practice, that means boards and devices based on most Rockchip, Allwinner, and Amlogic processors will have 3D graphics acceleration out of the box.
