Summary:	rockchipdrm, panfrost js fault, RK3288
Product:	Drivers	Reporter:	Alexander von Gluck (kallisti5)
Component:	Video(Other)	Assignee:	drivers_video-other
Status:	NEW ---
Severity:	normal
Priority:	P1
Hardware:	ARM
OS:	Linux
Kernel Version:	5.6.6-300.fc32.armv7hl	Subsystem:

Description Alexander von Gluck 2020-06-26 13:05:06 UTC

Reproduction:

Laid down a master u-boot at the expected locations from Haiku's builds here:
https://github.com/haiku/firmware/tree/master/arm/tinkerboard

Placed onto a Fedora 32 server arm (32-bit) image.



No GPU output.  Redirected console to ttyS3, and witnessed several fatal errors from panfrost driver:

Comment 1 Alexander von Gluck 2020-06-26 13:09:58 UTC

Created attachment 289891 [details]
FDT from Fedora 32 for tinkerboard

Attaching the FDT used for Asus Tinkerboard from Fedora 32 boot media.

Here's the kernel + initrd + kernel args:


label Fedora-Server-armhfp-32-1.6 (5.6.6-300.fc32.armv7hl)
        kernel /vmlinuz-5.6.6-300.fc32.armv7hl
        append ro root=UUID=a853e04d-be77-4d91-a864-4d9544e60eb6 LANG=en_US.UTF-8 earlyprintk systemd.journald.forward_to_console=1 console=ttyS3,115200n8
        fdtdir /dtb-5.6.6-300.fc32.armv7hl/
        initrd /initramfs-5.6.6-300.fc32.armv7hl.img



console=ttyS3,115200n8 produces u-boot output on UART2, kernel output on UART3.  

putting everything on console=ttyS2,115200n8 (the more correct setting) seems to  lose a lot of kernel logging.

Comment 2 Alexander von Gluck 2020-06-26 17:37:46 UTC

Adding this to the kernel arguments at boot resolved  this issue for me:

rd.driver.blacklist=panfrost
