stm32mp157 framebuffer support in new ST BS Release

[AZaki.2]

Hi,

when trying the new ST BSP release base on linux kernel 6.1.82 on my stm32mp157f-dk2 I noticed that the legacy framebuffer support is not working anymore.

this was working perfectly on the previous release with linux kernel 6.1.28.

I didn't succeed in getting it working again, here is a fragment of my linux kernel configuration:

CONFIG_DRM=y
CONFIG_DRM_STM=y
CONFIG_DRM_STM_DSI=y
CONFIG_DRM_PANEL_ORISETECH_OTM8009A=y
CONFIG_DRM_SII902X=y
CONFIG_FB=y
CONFIG_FB_SIMPLE=y
CONFIG_BACKLIGHT_CLASS_DEVICE=y
CONFIG_BACKLIGHT_PWM=y
CONFIG_BACKLIGHT_GPIO=y
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE_ROTATION=y
CONFIG_DRM_FBDEV_EMULATION=y
CONFIG_LOGO=y

can you please advice how to get it working again ?

I don't plan to use DRM.

Best regards

Hello @AZaki.2 ,
Thank you for your feedback. Can you just precise me your way to test and validate or not if the feature works as I will certainly need to reproduce myself. 

Kind regards,
Erwan.

hello,

a simple test is:

$ dd if=/dev/urandom of=/dev/fb0

you should get some nice noise image on the screen if framebuffer support is working

[AZaki.2]

here are some noticeable traces differences between :

Hello @AZaki.2 ,
I ask myself if this is not due to the continuous display features. Can you remove the default-on property from your Linux device tree on ltdc ? 

Kind regards,
Erwan.

I tried it yesterday already by reverting this commit:

https://github.com/STMicroelectronics/linux/commit/c1c0bc827fabea1c73b7dee71b90e7cdef5c9290

But it didn't change anything.

[Erwan SZYMANSKI · Accepted solution]

@AZaki.2 ,
I have just tested it and it works for me without patching the kernel or DTS, just by changing the configuration. I put you my own configuration in attachment for you to double check.

After the boot I checked dmesg | grep fb0 :

[ 0.734796] simple-framebuffer ddc00000.framebuffer: [drm] fb0: simpledrmdrmfb frame buffer device
[ 3.272776] stm32-display 5a001000.display-controller: [drm] fb0: stmdrmfb frame buffer device

Finally, I stopped Weston with  systemctl stop weston-graphical-session and I did your own test, worked for me.

Kind regards,
Erwan.

[AZaki.2]

@Erwan SZYMANSKI  thanks it worked :)

I need to pinpoint to the Kernel config that made the difference.

[AZaki.2]

I did some more test and it looks like the framebuffer isn't working reliably anymore.

I don't see in the dmesg any errors.

I did multiple reboot/reset of the stm32mp157f-dk2 and sometimes it's not working (system is up but no frambuffer , somtimes it hangs completely), this never happened with previous release.
