+Subject: [PATCH] drivers/firmware: skip simpledrm if nvidia-drm.modeset=1 is
+ set
+
+The Nvidia proprietary driver has some bugs that leads to issues if used
+with the simpledrm driver. The most noticeable is that does not register
+an emulated fbdev device.
+
+It just relies on a fbdev to be registered by another driver, that could
+be that could be attached to the framebuffer console. On UEFI machines,
+this is the efifb driver.
+
+This means that disabling the efifb driver will cause virtual consoles to
+not be present in the system when using the Nvidia driver. Legacy BIOS is
+not affected just because fbcon is not used there, but instead vgacon.
+
+Unless a VGA mode is specified using the vga= kernel command line option,
+in that case the vesafb driver is used instead and its fbdev attached to
+the fbcon.
+
+This is a problem because with CONFIG_SYSFB_SIMPLEFB=y, the sysfb platform
+code attempts to register a "simple-framebuffer" platform device (that is
+matched against simpledrm) and only registers either an "efi-framebuffer"
+or "vesa-framebuffer" if this fails to be registered due the video modes
+not being compatible.
+
+The Nvidia driver relying on another driver to register the fbdev is quite
+fragile, since it can't really assume those will stick around. For example
+there are patches posted to remove the EFI and VESA platform devices once
+a real DRM or fbdev driver probes.
+
+But in any case, moving to a simpledrm + emulated fbdev only breaks this
+assumption and causes users to not have VT if the Nvidia driver is used.
+
+So to prevent this, let's add a workaround and make the sysfb to skip the
+"simple-framebuffer" registration when nvidia-drm.modeset=1 option is set.
+
+This is quite horrible, but honestly I can't think of any other approach.
+
+For this to work, the CONFIG_FB_EFI and CONFIG_FB_VESA config options must
+be enabled besides CONFIG_DRM_SIMPLEDRM.
