After update kernel tree patch, subdirectories pm and rf from arch/arm/mach-sunxi/ were removed and now during the compiling I have the following errors:

drivers/built-in.o: In function platform_wifi_power_on': :(.text+0x1c94e0): undefined reference towifi_pm_get_mod_type'
:(.text+0x1c9548): undefined reference to wifi_pm_power' drivers/built-in.o: In functionplatform_wifi_power_off':
:(.text+0x1c95c0): undefined reference to `wifi_pm_power'

and current pm.c looks like fake.

This sources can be used for A20 SoC?

If yes witch arch i must used

can't build full stack Mali driver mali_drm.ko from r4p0-00rel0 because absent file drm_sman.h in /include/drm

config sun8iw5
the following error terminates build :

hello allwinner-zh,
I am trying to write a driver for the OV5674 image sensor and I found sources in your repository. What is the status of this driver, which functions are supported?

See this for more details:

Binary only

The Power VR G6230 GPU now supports ES 3.2 / Vulkan 1.0. However, the current A80 hive only seems to support ES 3.0.

Here is a working Dmesg:

So-core have no any sources and documents.

Any maintainance for Linux Kernel ? Besides Kernel 3.4, is there any documentation for building current Kernel for allwinner chips, say H3?

Cheers
Pei

Kernel is very complex thing, so it's very preferred to have commit history imported to repository, git history can be very helpful for issue solving. And necessary to understand changes between source drops

As mentioned in #16 (comment), you still have the root backdoor in the A83T branch..

This looks trivial, only mapping to hardware registers. Please consider publishing this in source form so a kernel can be lawfully distributed with sunxi_geth driver enabled.

With this in binary-only form it is not possible to distribute a resulting kernel with this driver enabled while complying with the kernel GPL license.

Allwinner Technology committed to resolving Linux Kernel software issue

Zhuhai, China - Allwinner Technology.Co.Ltd (SHE: CN:300458) is working with its device manufacturers to fix a current software issue. We are aware that code, which was supplied to device manufacturers for the purpose of developing products, should have been removed prior to shipping. We recommend that anyone who is concerned about this issue should contact the relevant device manufacturer.

In relation to the source code on Github, it is released for the open source community only and not for shipping certain devices. Since a debugging function is not needed it has subsequently been removed.

Allwinner is committed to producing quality SoC’s with security a key priority. We are currently working hard to address this issue and revising our current processes so we can continue to evolve our range of SoC’s in the future.

will the drivers here will help to detect connected USB HID device.? It is recognized in Nexus 7 tablet but ont on pcDuino3. I am using same app in both.

It looks like the source for USB OTG or device-mode support is missing? Thanks!

drivers/media/video/sunxi-fd/lib/libfd

Please consider publishing this in source form so a kernel can be lawfully distributed with sunxi_fd driver enabled, or drop support for this module if publishing source is not possible. I have not analyzed the contents of libfd.

With this in binary-only form it is not possible to distribute a resulting kernel with this driver enabled while complying with the kernel GPL license.
