[PATCH 0/4] add GPU for RK356x SoCs

This is a respin of Ezequiel's series which adds GPU for RK3568 [0]:

I hope to have resolved all DT-binding issues and added cooling map and trip points
which can make the GPU a cooling device.

Tested with mesa 21.3.0 on quartz64-a board.

[PATCH 1/4] dt-bindings: gpu: mali-bifrost: Allow up to two clocks

[Alex Bee]

Commit b681af0bc1cc ("drm: panfrost: add optional bus_clock")
added an optional bus_clock to support Allwinner H6 T-720 GPU.
Increase the max clock items in the dt-binding to reflect this.

Bifrost GPU in Rockchip RK3568 SoCs also has a core and a bus clock
and it gets added here in a (very) similar way it was done for
allwinner,sun50i-h6-mali compatible in arm,mali-midgard binding.

That's midgard and this is bifrost... Driver changes are somewhat 
irrelevant.

I guess that one is insufficient.

[PATCH 2/4] arm64: dts: rockchip: Add GPU node for rk3568

[Alex Bee]

From: Ezequiel Garcia <ezequiel@collabora.com>

Rockchip SoCs RK3566 and RK3568 have a Mali Gondul core
which is based on the Bifrost architecture. It has
one shader core and two execution engines.

Quoting the datasheet:

Mali-G52 1-Core-2EE
* Support 1600Mpix/s fill rate when 800MHz clock frequency
* Support 38.4GLOPs when 800MHz clock frequency

[PATCH 2/4] arm64: dts: rockchip: Add GPU node for rk3568

[Alex Bee]

From: Ezequiel Garcia <ezequiel@collabora.com>

Rockchip SoCs RK3566 and RK3568 have a Mali Gondul core
which is based on the Bifrost architecture. It has
one shader core and two execution engines.

Quoting the datasheet:

Mali-G52 1-Core-2EE
* Support 1600Mpix/s fill rate when 800MHz clock frequency
* Support 38.4GLOPs when 800MHz clock frequency

Alex, Ezequiel

I'm playing with 5.16 mainline on rk3566 based tvbox (x96-x6)

Box boots and I have working SD card, Eth, HDMI.

I applied this series as I want to get GPU working but I'm getting:

[    3.169144] panfrost fde60000.gpu: get clock failed -517
[    3.169646] panfrost fde60000.gpu: clk init failed -517

Maybe you have some hints here?

Alex, Ezequiel

I'm playing with 5.16 mainline on rk3566 based tvbox (x96-x6)

Box boots and I have working SD card, Eth, HDMI.

I applied this series as I want to get GPU working but I'm getting:

[    3.169144] panfrost fde60000.gpu: get clock failed -517
[    3.169646] panfrost fde60000.gpu: clk init failed -517
[    3.213653] panfrost fde60000.gpu: get clock failed -517
[    3.214156] panfrost fde60000.gpu: clk init failed -517
[    3.230505] panfrost fde60000.gpu: get clock failed -517
[    3.231006] panfrost fde60000.gpu: clk init failed -517
[    3.258072] panfrost fde60000.gpu: get clock failed -517
[    3.258575] panfrost fde60000.gpu: clk init failed -517

Maybe you have some hints here?

517 is EPROBE_DEFER, which implies it's waiting for the relevant clock 
provider to show up. I see from patch #2 that SCMI is involved, so I'd 
check that that's working and you have CONFIG_COMMON_CLOCK_SCMI enabled.

Robin,

Many thx!
Indeed issue was with SCMi CLK.
Now i see:

[    3.092350] panfrost fde60000.gpu: clock rate = 594000000
[    3.092906] panfrost fde60000.gpu: bus_clock rate = 500000000
[    3.138340] panfrost fde60000.gpu: clock rate = 594000000
[    3.138904] panfrost fde60000.gpu: bus_clock rate = 500000000
[    3.171244] panfrost fde60000.gpu: clock rate = 594000000
[    3.171888] panfrost fde60000.gpu: bus_clock rate = 500000000

good.

(unfortunately mesa 21.3.4 still goes with llvmpipe but this seems to be other issue i need to investigate)

thx again!

[PATCH v2 0/4] RK3568 GPU

[Ezequiel Garcia]

I've decided to split the GPU off previous series:

https://lore.kernel.org/linux-rockchip/2147216.TLkxdtWsSY@diego/

This series now contains only the GPU support, as the VPU
needs a tiny rework.

This is compiled tested only, in this case. Similar patches
have been tested on a v5.10-based kernel, so I'd say it's good
to go.

The mesa side is merged https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/10771
and can be tested without a display, using something like weston --backend=headless-backend.so,
which provides an environment for GL to work.
