DRM drivers will not perform display-mode changes or accelerated rendering and only the system framebuffer will be available if it was set-up. But only a few DRM drivers currently check for nomodeset, make this driver to also support the command line parameter.

Fix this by making deallocating MMIO only on Gen2 machines and implement removal for Gen1 Fixes: 76c56a5affeb ("drm/hyperv: Add DRM driver for hyperv synthetic video device") Signed-off-by: Mohammed Gamal <mgamal@redhat.com> Reviewed-by: Deepak Rawat <drawat.floss@gmail.com> Signed-off-by: Deepak Rawat <drawat.floss@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211119112900.300537-1-mgamal@redhat.com 2021-07-01T09:11:55+00:00 Thomas Zimmermann tzimmermann@suse.de 2021-06-29T13:58:33+00:00 urn:sha1:97c9bfe3f6605d41eb8f1206e6e0f62b31ba15d6 Print the name of the DRM driver when taking over fbdev devices. Makes the output to dmesg more consistent. Note that the driver name is only used for printing a string to the kernel log. No UAPI is affected by this change.
