Drivers Allwinner A83t
This firmware flash file can also help to fix a lot of problems on your Oppo A83T. Some problems like hanging, battery drain, app crashing, and other problems. You can use this stock rom to remove the locked screen, remove root, fix many system errors, and unbrick Oppo A83T. Firmware Filename: OppoA83T11A.31190409.zip. new driver allwinner/ac100: rtc and audio codec for a83t. Some of Allwinner SoCs like A83T and A64 SoCs contain DE2 rotate core which can flip image horizontal and vertical and rotate it in 90 deg. It support a lot of output formats, but a bit less capture formats. All YUV input formats get converted to yuv420p, while RGB formats are preserved. Patches 1-2 fix few issues with DE2 clocks.
The purpose of this page is to try and define sub-goals and milestones for the mainlining effort, containing goals and sub-goals with milestones for adding Allwinner support in the upstream mainline Linux Kernel.
|
The idea is to submit the code needed to run the Linux kernel on Allwinner SoCs upstream, ie. to the official Linux kernel.
This can be achieved by following the concept outlined in the Your new ARM SoC Linux support check-list! article published by Thomas Petazzoni from Bootlin.[1][2]
Where relevant, I have attempted to include who is currently working on an item, mostly separate from any particular mainlining goal.
The Mainline Kernel howto contains the currently used repositories for the mainlining process. The U-Boot repository and toolchain is described in the Mainline U-Boot howto.
The Mainline Kernel category gives an overview of currently supported devices.
Status Matrix
The goal of this matrix is to give an easy view of work on each SoC worked on by linux-sunxi.

Drivers that can still be improved/added
Nobody works on these features. If you're interested, you can pick one of these add your name to them and move them to one of the sections above, to indicate you're working on the driver/feature.
- sunxi-musb driver lacks DMA support (with current driver, USB gadgets are limited to PIO, limiting speed to 10MiB/s and causing large CPU)
- DE2 driver has buggy layer support, see [1]
- DE1/DE2/DE3 writeback support
- A64 audiocodec driver components (sun8i-codec and sun50i-codec-analog) lack support for jack detection

- ↑Allwinner H6 has a quirky PCIe controller that doesn't map the PCIe address space properly to CPU, and accessing the PCIe config space, IO space or memory space needs to be wrapped. As Linux doesn't wrap PCIe memory space access, it's not possible to do a proper PCIe controller without using an hypervisor. The BSP kernel modifies the driver to wrap the access, so it's also not generic, and only devices with modified driver will work. https://forum.armbian.com/topic/13529-a-try-on-utilizing-h6-pcie-with-virtualization/
