Hi, This started since 5.14-rc1. The following error appears in dmesg (as of 5.14-rc7) when I build the kernel with CONFIG_DRM_SIMPLEDRM=m [ 3.252275] [drm] Initialized simpledrm 1.0.0 20200625 for simple-framebuffer.0 on minor 0 [ 3.252298] simple-framebuffer simple-framebuffer.0: [drm] *ERROR* fbdev: Failed to setup generic emulation (ret=-22)
Thanks for trying out the driver and reporting back. I suspect that your system uses a color format that is not yet supported. But let's see.
What's the platform you're on?Simpledrm depends on the system framebuffer to be configured by the UEFI BIOS or boot loader. What's the resolution and color format on your system?
Could you please boot the kernel with the command-line option drm.debug=0x1ff and provide all dmesg output the is related to DRM?
Best regards Thomas
thanks, Amanoel
