This patch series inserts DRRS into frontbuffer tracking mechanism. 1. Previous submission for this feature was designed considering only eDP DRRS. In this series, apart from following fb tracking, changes have been made to make structures generic so that it can be of use to any other code addition to support DRRS with other display types. 2. DRRS support is checked based on VBT setting and panel's capability (if more than one RR is supported). 3. Based on DRRS support availability, related structures are initialized or cleaned up through calls from enable/disable DDI respectively. 4. Since flip() indicates busyness, changes have been made to invalidate DRRS during flip. This changes RR back to preferred mode RR. New work to set low RR is scheduled after a delay of 1 second. 5. This series includes patches to support RR switching on all platforms. v2: As discussed with Daniel, discarding the patch which added a module param to specify the delay before entering DRRS. This delay has been fixed to 1 second. The call to invalidate DRRS from page_flip still remains - will be changed (or kept as is) depending on the behavior on Android.. Right now testing is done using vbltest in libdrm.. But i-g-t for DRRS is WIP.
