ZwpLinuxDmabufFeedbackV1FormatTableEvent class

format and modifier table

This event provides a file descriptor which can be memory-mapped to access the format and modifier table.

The table contains a tightly packed array of consecutive format + modifier pairs. Each pair is 16 bytes wide. It contains a format as a 32-bit unsigned integer, followed by 4 bytes of unused padding, and a modifier as a 64-bit unsigned integer. The native endianness is used.

The client must map the file descriptor in read-only private mode.

Compositors are not allowed to mutate the table file contents once this event has been sent. Instead, compositors must create a new, separate table file and re-send feedback parameters. Compositors are allowed to store duplicate format + modifier pairs in the table.
