Hello!

Explain to me please, what's the problem with support for H5 processors?

Drivers located here: https://developer.arm.com/products/software/mali-drivers/user-space ,

and here: https://developer.arm.com/products/software/mali-drivers/utgard-kernel , not enough? 

 

There you go:

H5 is mainline only. So, every build is experimental at the moment.

Left to be done

Easy Tasks

Following drivers should be doable by someone with no or a small kernel development experience:

• One Wire / 1-Wire (dedicated HW only present on A31/A80)
• Smart Card Reader

Medium and Difficult Tasks

These drivers require some good knowledge of the kernel internals, plus a good experience with such piece of hardware.

• Audio Related drivers
• Audio Decoding Engine (Only exists in A10)
• V4L driver for G2D/Mixer is based on samsung g2d and fimc driver. Only initial work started. [1]

Troublesome

• Memory Stick (missing hardware?)
• TV Decoder (Analog in, no existing driver, no datasheet)
• Transport Stream (DVB)
• PATA (old tech, while still interesting for Compact Flash, possibly removed from A20, though A20 memory map still mentions it)
• GPS backend IP (only present on A10, not much interesting, as all modern GPS receivers have MCU with UART output, no documentation)
• Ac200: No datasheet, at least the ephy part seems to work in "generic PHY" mode

Unlikely

These are too far off the track third party drivers making it unlikely they will ever get accepted mainline.

• Mali driver <-------------------------- !!!!!!!!!!!!!!!!!!!!

Related but separate

• Device-specific drivers

 

This is the mainlining effort table
In order to have a working, Mali driver, on top of a mainline kernel, something different is required, such a working DRM driver and the UPM module
