The nomodeset kernel command line parameter is used to prevent the KMS/DRM
drivers to be registered/probed. But only a few drivers implement support
for this and most DRM drivers just ignore it.
This patch series is a v2 to make DRM drivers to honour nomodeset. It is
posted as separate patches to make easier for drivers maintainers to ack
or pick them independently at their own pace.
The drm_module_{pci,platform}_driver() helper macros are added, which are
just wrappers around module_{pci,platform}_driver() but adding a check for
drm_firmware_drivers_only() and returning -ENODEV if that is true.
PCI and platform DRM drivers are then modified in the following patches to
make use of those macros.
For drivers that have custom module init/exit, the check is added to these
functions instead. Since the drm_*_module_driver() macros are only for the
default case when the init/exit just register/unregister the driver type.
In v1 all KMS/DRM drivers were included but v2 only includes KMS drivers,
and only the the PCI and platform DRM drivers. A follow-up series might
do the same for rendering-only and USB/SPI/I2C drivers, but it will need
more discussion to agree if that's desirable.
I've built tested with 'make allmodconfig && make M=drivers/gpu/drm' but I
don't have hardware to test the drivers, so review/testing is appreciated.
Best regards,
Javier
Changes in v2:
- Add drm_module_{pci,platform}_driver() macros and put the check there
(Thomas Zimmermann).
- Use the drm_module_*_driver() macros if possible (Thomas Zimmermann).
- Leave the DRM drivers that don't set the DRIVER_MODESET driver feature
(Lucas Stach).
- Leave USB/SPI/I2C drivers and only include PCI and platform ones
(Noralf Trønnes).
- Add collected Reviewed-by tags
