Linux Kernel 4.18.8
#4

Possibly because threads tending to the little cores rather than being fixed to a big core. I think the CONFIG_ARM_ROCKCHIP_CPUFREQ in 4.4 is probably the thing we really need?  I did notice .../arch/arm64/configs/rockchip_linux_defconfig has a whole heap of CONFIG_CRYPTO parameters set Y and keep meaning to check my config. I thought the openSSL results I got from TKaiser sbc-bench were poor compared to Firefly.

Sorry - I no longer use any SATA nor SSD (except occasionally via USB for backup!) Since getting my NVMe to work (thanks again Bullet64!) I figure that is the way to go. And I do not have that much data beyond NVMe capacities.

A funny fact is, that all other platforms get support/developement in the kernel. But not our beloved RockPro64.
See https://git.kernel.org/pub/scm/linux/ker...h=for-next

As soon as I posted my earlier reply with a list of 6 things that do not work I thought it was possibly too negative. The reality is that 4.18 is 99% brilliant, and having learned how to compile a kernel, playing with the CONFIG parameters is great fun. Let alone tampering with the DTS. My latest version I swapped rk3399-oppp.dtsi for rk3399-op1-opp.dtsi to get "official" 2/1.5GHz!

I do see quite a few Arm & Rockchip patches in the changelogs so am really optimistic for this SBC. For sure we need Ayufan back cooking as well and hopefully upstream some stuff if Rockchip do not.
  • ROCKPro64 v2.1 2GB, 16Gb eMMC for rootfs, SX8200Pro 512GB NVMe for /home, HDMI video & sound, Bluetooth keyboard & mouse. Arch (5.19 kernel, Openbox desktop) for general purpose daily PC.
  • PinePhone Pro Explorer Edition daily driver, Tow-boot on SPI, Arch/phosh on eMMC
  • PinePhone BraveHeart now v1.2b 3/32Gb, Tow-boot with Arch/Phosh on eMMC
