From: Daniel Kurtz <djkurtz@xxxxxxxxxxxx> The 'mode' is the modeline information which specifies the ideal mode requested by the mode set initiator (usually userspace). The 'adjusted_mode' is the actual hardware mode after all the crtcs and encoders have had a chance to "fix it up". The adjusted_mode starts as a duplicate of the mode in drm_crtc_helper_set_mode(), and gets modified as required. There is no reason to touch the original requested mode. In fact, doing so will cause us to think a new mode is being requested whenever userspace tries to establish a new framebuffer with drmModeSetCrtc(), since userspace will still be using the ideal mode, but the crtc will be incorrectly comparing it against the adjusted_mode.
