Why is this sent to fbdev list? Is this related to the hyperv-fb patches?
Yes, the hyperv-fb patches depend on this one.
Greg has picked it up meanwhile, that's why v4 + v5 of the patch series
don't include it any more.

Remove firmware framebuffer before initializing hyperv-fb. Needed
on gen2 virtual machines. Letting register_framebuffer handle the
switchover results in efifb still being active while hyperv graphics
are initialized, which in turn can make the linux kernel hang.

On Gen2 firmware, Hyper-V does not emulate the PCI bus. However, the MMIO
information is packaged up in DSDT. Extract this information and export it
for use by the synthetic framebuffer driver. This is the only driver that
needs this currently.

This patch adds a pci stub driver to hyper-fb. The hyperv framebuffer
driver will bind to the pci device then, so linux kernel and userspace
know there is a proper kernel driver for the device active. lspci shows
this for example:
is that the xorg vesa driver will not attach to the
device and thus the Xorg server will automatically use the fbdev
driver instead.
