Linux Kernel 4.18.8
#2
Saw this on your forums - many thanks to av (or whoever has done the cooking)!

Seems like a couple of things are improved since rc8 (e.g. DRM-ROCKCHIP doesn't cause major delays/timeouts) - I hope you are OK if I use this thread to list problems I have with 4.18 (in fact 4.18.8 now)?

1) The video/armsoc/DRM/midgard is not quite right. Sorry my knowledge in this area is dangerous so apologies for any terminology abuses. The most obvious problem is in Xorg.log

Code:
[    36.693] (II) ARMSOC: Driver for ARM Mali compatible chipsets
[    36.693] (WW) Falling back to old probe method for armsoc
[    36.693] (II) No BusID or DriverName specified - opening /dev/dri/card0
[    36.693] (EE) ERROR: Cannot set the DRM interface version.
[    36.693] (EE) ERROR: Cannot open a connection with the DRM - Permission denied


Not sure if the early failure to bind to HDMI is significant?

Code:
$ dmesg | grep drm

[    1.420145] rockchip-drm display-subsystem: Linked as a consumer to ff900000.vop

[    2.260483] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[    2.261066] [drm] No driver support for vblank timestamp query.

2) Sound - no chance on HDMI but seems almost there on ES8316 but not quite again. And again my skills around sound are pathetic. The first time I try to play something with mpv the screen looks like it is playing, but nothing comes through the speakers, and dmesg has

PHP Code:

3) The schedulling is not right: with either ondemand or performance high CPU jobs land on the little cores. I guess CONFIG_ARM_ROCKCHIP_CPUFREQ needs to be ported from 4.4?

4) Still get an infinite loop at boot "running CQE recovery" if eMMC is plugged in

5) This seems to be a defect in the DT but I cannot find it:

Code:
$ dmesg | grep vcc_sdio
[    2.092922] vcc_sdio: Bringing 3300000uV into 3000000-3000000uV
[    2.148951] vcc_sdio: unsupportable voltage range: 3300000-3000000uV

6) Similarly think this is an attempt to define OTG on USB2 whereas it should be the USB3 ports

Code:
$ dmesg | grep otg
[    1.818420] OF: graph: no port node found in /syscon@ff770000/usb2-phy@e450/otg-port
  • 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
