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.

  1. Aug 28, 2020 This patch add the support only for the Allwinner A83T MIPI CSI-2. Currently, the driver does not support the V3s MIPI CSI-2 controller. On the A83T, the CSI controller is the same as the other V3s Soc, but.
  2. D88 is to use Allwinner A83T solutions, integrated with the multimedia decoding, LCD driver, WIFI, bluetooth, Ethernet, support the majority of current popular video and image format decoding and support an MIPI/LVDS screen, etc., can drive all kinds of TFT LCD display, greatly simplify the whole system design, SD card, more stability and is very suitable for advertising machine, cash register, digital signage, vehicle intelligent terminal motherboard, etc.

The A83T has 3 USB PHYs, 1 for OTG, 1 for standard USB, 1 for USB HSIC. The phy initialization procedure is very different from other SoCs, but the PMU bits are the same, with additional bits for HSIC.

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

  4. ↑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/

Drivers Allwinner A83t Windows 7

The A83T has 3 USB PHYs, 1 for OTG, 1 for standard USB, 1 for USB HSIC.
The phy initialization procedure is very different from other SoCs, but
the PMU bits are the same, with additional bits for HSIC.
