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/bochs: add Bochs PCI ID for Simics model

2021-09-15T06:21:32+00:00

Current (and older) Simics models for the Bochs VGA used the wrong PCI vendor ID (0x4321 instead of 0x1234). Although this can hopefully be fixed in the future, it is a problem for users of the current version, not the least because to update the device ID the BIOS has to be rebuilt in order to see BIOS output. Add support for the 4321:1111 device number in addition to the 1234:1111 one. Signed-off-by: H.

drm/bochs: Move to tiny/

2021-07-05T06:54:44+00:00

The bochs driver is only ~600 lines of code. Putting it into tiny/ cleans up the DRM directory slightly. Some style problems were fixed and unneeded include statements were removed. No functional changes. v2: * make bochs_mode_funcs static (Daniel, kernel test robot) * rebase onto aperture API changes Signed-off-by: Thomas Zimmermann Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20210702075434.27677-2-tzimmermann@suse.de
