Create a simple fbdev device during SimpleDRM setup so legacy user-space and fbcon can use it.
fbdev deletion is quite buggy. A unregister_framebuffer() call followed by a printk() causes NULL-derefs in hide_cursor() and other places in the VT layer. Hence, we leak the fbdev device currently to make the VT layer happy. This needs to be fixed soon! Otherwise, we need a "depends !VT" line for SimpleDRM.
diff --git a/drivers/gpu/drm/simpledrm/Makefile b/drivers/gpu/drm/simpledrm/Makefile
simpledrm-y := simpledrm_drv.o simpledrm_main.o simpledrm_mem.o
+ifdef CONFIG_DRM_SIMPLEDRM_FBDEV
simpledrm-y += simpledrm_fbdev.o
+endif
I think that's:
- simpledrm-$(CONFIG_DRM_SIMPLEDRM_FBDEV) += simpledrm_fbdev.o
Ugh, I got errors trying that because SIMPLEDRM_FBDEV is a boolean but SIMPLEDRM is a tristate. But I guess I tried: obj-$(CONFIG_DRM_SIMPLEDRM_FBDEV) += simpledrm_fbdev.o which obviously fails if SIMPLEDRM=m and SIMPLEDRM_FBDEV=y. I will try to fix that.
Thanks David
