Revert "drm/mgag200: Add vblank support"

2024-10-17T06:49:45+00:00

This reverts commit 6c9e14ee9f519ee605a3694fbfa4711284781d22. This reverts commit d5070c9b29440c270b534bbacd636b8fa558e82b. This reverts commit 89c6ea2006e2d39b125848fb0195c08fa0b354be. The VLINE interrupt doesn't work correctly on G200SE-A (at least). We have also seen missing interrupts on G200ER. So revert vblank support. Fixes frozen displays and warnings about missed vblanks. [ 33.818362] [CRTC:34:crtc-0] vblank wait timed out From the vblank code, the driver only keeps the register constants and the line that disables all interrupts in mgag200_device_init(). Both is still useful without vblank handling.

drm/mgag200: Use video aperture helpers

2024-10-14T13:28:47+00:00

DRM's aperture functions have long been implemented as helpers under drivers/video/ for use with fbdev. Avoid the DRM wrappers by calling the video functions directly.

drm/mgag200: Remove BMC output

2024-08-09T06:13:48+00:00

Mgag200's BMC connector tracks the status of an underlying physical connector and updates the BMC status accordingly. This functionality works around GNOME's settings app, which cannot handle multiple outputs on the same CRTC. The workaround is now obsolete as the VGA-BMC connector handles BMC support internally. Hence, remove the driver's code and the BMC output entirely.

drm/mgag200: vga-bmc: Control BMC scanout from encoder

2024-08-09T06:13:47+00:00

Move calls to stop and start BMC scanout from CRTC helpers to the VGA-BMC encoder's atomic_disable and atomic_enable. Makes the BMC scanout transparent to the CRTC. DRM's atomic helpers call an encoder's atomic_disable and atomic_enable helpers for all enabled encoders. The BMC stops scanning out the VGA signal if modeset disables the VGA encoder, and starts scanning out if the modeset enables the VGA encoder.

drm/mgag200: vga-bmc: Control CRTC VIDRST flag from encoder

2024-08-09T06:13:47+00:00

Control the VIDRST pin from the VGA-BMC encoder's atomic_check and remove the respective code from CRTC. Makes the VIDRST functionality fully composable. The VIDRST pin allows an external clock source to control the SYNC signals of the Matrox chip. The functionality is part of the CRTC, but depends on the presence of the clock source. This is the case for some BMCs, so control the pin from the VGA-BMC output.

drm/mgag200: vga-bmc: Transparently handle BMC

2024-08-09T06:13:46+00:00

The VGA-BMC connector selects the VGA output if a display has been attached to the physical connector. Otherwise it selects the BMC output. In any case, the connector status is set to 'detected', so that the userspace compositor displays to it. Depending on the setting, the connector's display modes either come from the VGA monitor's EDID or from an internal list of BMC-compatible modes.
