This allows the application to request frames be displayed at specific absolute times, using the same timebase as that provided in vblank events. Support for this extension has been implemented for the x11 and display backends; adding support to other backends should be reasonable straightforward for one familiar with those systems and should not require any additional device-specific code. v2: Adjust GOOGLE_display_timing earliest value. The earliestPresentTime for an image cannot be before the previous image was displayed, or even a frame later (in FIFO mode). Make GOOGLE_display_timing use render completed time. Switch from VK_PIPELINE_TOP_OF_PIPE_BIT to VK_PIPELINE_STAGE_ALL_COMMANDS_BIT so that the time reported to applications as the end of rendering reflects the latest possible value to ensure that applications don't underestimate the amount of work done in the frame. v3: Adopt Jason Ekstrand's coding conventions. Declare variables at first use, eliminate extra whitespace between types and names. Wrap lines to 80 columns. Suggested-by: Jason Ekstrand v4: Adapt to changes in MESA_query_timestamp extension v5: Squash core bits and anv/radv wrappers into a single patch Suggested-by: Jason Ekstrand v6: Switch from MESA_query_timestamp to EXT_calibrated_timestamps v7: Ensure we target frame no earlier than desired. This means rounding the target frame up, rather than selecting the nearest one.
