Re: [PATCH v2 0/5] arm64: dts: rockchip: support mail and IPA thermal for rk3399

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Rob & Heiko,

Do we have the chance to merge these patches?

I'm try to bring up the display and run webgl for testing with my github on
https://github.com/Caesar-github/rockchip/commits/gru/next-stable-chromeos

I believe the Rocky@RK will post patches to support the other SoCs after.

This series patches supported the mail in devicetree and used the
thermal IPA by default.

Verified with kernel is based on Linus's master branch and Heiko's
v4.14-armsoc-tmp/dts64 branch. ( The Linux version 4.12.0 for now).

The most rockchip SoCs will be supported with IPA mode for thermal
in later.

History version:
1. The first version found on
https://www.spinics.net/lists/arm-kernel/msg593118.html

Tested on Kevin board with bringing up ChromeOS.
OS VERSION:
     CHROMEOS_RELEASE_DESCRIPTION=9693.1.0 (Official Build) dev-channel kevin test

BIOS VERSION:
     Google_Kevin.8785.211.2017_06_20_1043

EC VERSION:
     Build info:    kevin_v1.10.217-24514961d 2017-07-03 07:46:36 wxt@nb

With the ARM's lastest mali driver TX011-SW-99002-r18p0-01rel0 on
https://developer.arm.com/products/software/mali-drivers/midgard-kernel

 From the bootup log:

And for thermal with IPA.
Try to run 'md5sum /dev/zero &' and octane/benchmark scripts to go up the temperature.
 From the scripts to have a look at the actual control.
"
while true; do grep "" /sys/class/thermal/thermal_zone[0-1]/temp /sys/devices/system/cpu/cpu[0-5]/cpufreq/scaling_cur_freq /sys/devices/platform/ff9a0000.gpu/devfreq/devfreq0/cur_freq;date;sleep .5; done &
"

Changes in v2:
As Heiko comments on https://patchwork.kernel.org/patch/9835939/
- interrupt-name use the lower case.
- use the correct compatible "arm,mali-t860"
- remove the clock name, since the mali only have one input clock.
- foo@ will produce warnings when used without reg property.
- update the commit to explain the two passive trip points changed.

Caesar Wang (5):
   dt-bindings: gpu: add the RK3399 mali for rockchip specifics
   dt-bindings: gpu: add a power_model optional properties for MALI
   arm64: dts: rockchip: add ARM Mali GPU node for RK3399 SoCs
   arm64: dts: rockchip: enable the GPU for RK3399-GRU
   arm64: dts: rockchip: update the thermal zones for RK3399 SoCs
