Mipi-dbi-spi display on SPI interface is non-working in X as well as Wayland #5615

Describe the bug

I have a small 240x240pixels display with a controller which is MIPI-DBI compliant (ST7789VW). Wrote a custom tinyDRM compliant driver for the display which was only working when booted to CLI; in X I was unable to get the desktop shown on the display. Find details on my custom driver + overlay: here https://forums.raspberrypi.com/viewtopic.php?t=355870

Then decided to switch to the in-tree driver and make use of 'panel-mipi-dbi.c' + it's related overlay instead to check if my custom driver has issues, or, if the result is the same.

I've created a panel.bin file in lib/firmware which has the required initialization commands for my display.

Tested my driver as well as the upstream driver of below kernels; non of them (!) is starting the SPI display in X. The display works when booted to CLI, when booting to GUI it works as long as FW is active, it's switched off/fails when KMS takes over:

Steps to reproduce the behaviour

Display which I'm currently testing with: https://www.waveshare.com/pico-lcd-1.3.htm

Any MIPI-DBI compliant display will do!

1.) Prepare a 'panel.bin' file according to the requirements explained in https://github.com/raspberrypi/linux/blob/cc08810f89e52337a99cc6ae5f53f08588357c5f/drivers/gpu/drm/tiny/panel-mipi-dbi.c The default overlay (https://github.com/raspberrypi/linux/blob/rpi-6.1.y/arch/arm/boot/dts/overlays/mipi-dbi-spi-overlay.dts) expects the file with parameters/commands for initialization from the file 'panel.bin' in '/lib/firmware'

2.) Change config.txt to start the SPI display with the right set of GPIO configuration

3.) see the display working in CLI and failing in X

Wrote a custom tinyDRM compliant driver for the display which was only working when booted to CLI; in X I was unable to get the desktop shown on the display.

If it's working at the console, then it's not a kernel issue.

X doesn't perform brilliantly with multiple DRM cards - it has concepts of source and sink providers, as reported by xrandr --listproviders. As I'd linked in the forum thread, I've been down that road before - https://forums.raspberrypi.com/viewtopic.php?p=1837374#p1837374

I'd suggest you wait for Bookworm as it uses Wayfire and Wayland which does work nicely with mutliple DRM cards.

aBUGSworstnightmare-rpi commented 1 year ago

Never been able to get the display started in X when following your suggestions; KMS will always end with a log-on box and a black SPI display.

There is no other display connected (No HDMI/DSI/DPI) during my testing, so how to make sure there is only one DRM card - the SPI - display?

Got It working once by accident when the GPU binding fatally failed, but was not able to reproduce/take logs (as I wasn't prepared for it to work).

From my Bookworm testing I figured out that Wayfire and Wayland have other issues. Anyhow, if you can share a link (via email) to latest Bookworm Beta (resigned from beta testing program because of various resonsl) I'm willing to test it with 6.5 kernel again.

6by9 commented 1 year ago

A comment from a colleague was that they needed a file /etc/X11/xorg.conf.d/99-vc4.conf:

Section "OutputClass"
    Identifier "vc4"
    MatchDriver "vc4"
    Driver "modesetting"
    Option "PrimaryGPU" "true"
EndSection

to get vc4 selected correctly as the primary X display.

You don't only have one card - v3d should exist and be doing the composition, with your SPI driver doing the display.

aBUGSworstnightmare-rpi commented 1 year ago

Created a file with the content shown, rebooted (just in case ) Also checked/setup providers by

Used screen configuration editor for switching the SPI on - not working -> back to log-on screen (which is funny as well as my OS is setup for auto-login).

@6by9: your post on the vc4.conf gave me the idea to do something else

sudo nano /etc/X11/xorg.conf.d/99-fbdev.conf adding below to the file

Section "Device" Identifier "FB Driver" Driver "fbdev" Option "fbdev" "/dev/fb0" EndSection

saving and reboot kicks the display alive, but is for sure not what we want.

I have same issue. I try to use ILI9341 display on Pi OS bookworm with Raspberry Pi Zero 2 W.

I installed Pi OS Lite bookworm to my microSD. I build my panel.bin using this sample and placed on /lib/firmware

I wired my display and set this on config.txt

dtparam=spi=on

dtoverlay=mipi-dbi-spi,spi0-0,speed=70000000
dtparam=width=320,height=240
dtparam=reset-gpio=25,dc-gpio=24
dtparam=backlight-gpio=23

After reboot, CLI messages are displaying on my display. I found these logs from dmesg

[    1.743999] simple-framebuffer 1ebaf000.framebuffer: fb0: simplefb registered!
[   12.102686] panel-mipi-dbi-spi spi0.0: [drm] fb0: panel-mipi-dbid frame buffer device

It seems my display are recognized fb0 (=first?) flamebuffer device. It looks nothing has problems.

I installed

sudo apt install mate-desktop-environment lightdm lightdm-gtk-greeter

I change login option by raspi-config, from console to graphical, reboot, there is nothing display after console messages.

I tried same steps on Pi OS Lite bullseye (kernel 6.1), It is working. I can see MATE desktop.

Edit: My friend tested with Pi 5, Pi 4, and Pi 3B+. Pi 5 and Pi 4 are working but Pi 3B+ is not.

6by9 commented 6 months ago

Edit: My friend tested with Pi 5, Pi 4, and Pi 3B+. Pi 5 and Pi 4 are working but Pi 3B+ is not.

Pi 4 & 5 on Bookworm default to using Wayfire instead of X. Wayfire supports multiple display devices far better than X, but has a significant overhead in use of 3D hardware for rendering. We are beta testing labwc which has much lower 3D requirements on the lower powered Pis. See https://forums.raspberrypi.com/viewtopic.php?p=2223184#p2223184 for basic install instructions.

As I said in https://github.com/raspberrypi/linux/issues/5615#issuecomment-1735501138 if it works in the console, then it's not a kernel issue.

Thank you! This was really good hint for me!

I change from X to Wayland in raspi-config on Pi Zero 2 W, and then I run sway from CLI, it works with mipi-dbi-spi display! (weston and cage also works) I can't run PIXEL desktop (something problems about OpenGL support on Pi 3/Zero2's SoC?). But it is enough for me at this time.
