drm: Move nomodeset kernel parameter to the DRM subsystem

2021-11-27T12:52:22+00:00

The "nomodeset" kernel cmdline parameter is handled by the vgacon driver but the exported vgacon_text_force() symbol is only used by DRM drivers. It makes much more sense for the parameter logic to be in the subsystem of the drivers that are making use of it. Let's move the vgacon_text_force() function and related logic to the DRM subsystem. While doing that, rename it to drm_firmware_drivers_only() and make it return true if "nomodeset" was used and false otherwise. This is a better description of the condition that the drivers are testing for.

drm/vboxvideo: Drop CONFIG_VGA_CONSOLE guard to call vgacon_text_force()

2021-11-27T12:52:18+00:00

It is already handled by the console.h macro since a stub inline function is defined for vgacon_text_force() if CONFIG_VGA_CONSOLE is not set. There's no need to have ifdefery in the driver when calling the function.

drm/vboxvideo: fix a NULL vs IS_ERR() check

2021-11-18T12:27:14+00:00

The devm_gen_pool_create() function never returns NULL, it returns error pointers.

drm/vbox: Use offset-adjusted shadow-plane mappings

2021-08-08T18:27:49+00:00

For framebuffers with non-zero offset fields, shadow-plane helpers provide a pointer to the first byte of the contained data. Use it in vbox. Signed-off-by: Thomas Zimmermann Acked-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20210803125928.27780-11-tzimmermann@suse.de

drm/vbox: Convert to Linux IRQ interfaces

2021-07-15T09:16:06+00:00

Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers don't benefit from using it.

drm/aperture: Pass DRM driver structure instead of driver name

2021-07-01T09:11:55+00:00

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.
