2020-01-07drm/vram-helper: Remove BO device from public interfaceThomas Zimmermann
TTM is an implementation detail of the VRAM helpers and therefore shouldn't be exposed to the callers. There's only one correct value for the BO device anyway, which is the one stored in the DRM device. So remove struct ttm_bo_device from the VRAM-helper interface and use the device's VRAM manager unconditionally. The GEM initializer function fails if the VRAM manager has not been initialized.

2019-12-10drm/ast: Store primary-plane format in struct ast_crtc_stateThomas Zimmermann
Reading the primary plane's framebuffer from the CRTC's atomic_flush() function is fragile as the plane state or framebuffer can be NULL. Instead, we let the plane's atomic_check() store the framebuffer format in the CRTC state. The CRTC always receives the framebuffer format that is currently programmed, or NULL if no mode has been set yet.

AST-specific CRTC state can be placed in the new struct ast_crtc_state. The atomic check functions of the CRTC and the primary plane will store the VBIOS mode info and the framebuffer format here.

I don't think there is anything outstanding so next week should just be fixes, but we'll see if I missed anything. I landed some fixes earlier in the week but got delayed writing summary and sending it out, due to a mix of sick kid and jetlag! There are some fixes pending, but I'd rather get the main merge out of the way instead of delaying it longer. It's also pretty large in commit count and new amd header file size.

The original bochs and vbox implementations of pin and unpin functions automatically reserved BOs during validation. This functionality got lost while converting the code to a generic implementation. This may result in validating unlocked TTM BOs. Adding the reserve and unreserve operations to GEM VRAM's pin and unpin functions fixes the bochs and vbox drivers.
