From bb5101aadc1675790983c7911092dd9abeec4651 Mon Sep 17 00:00:00 2001 From: Qiang Yu Date: Thu, 27 Mar 2025 10:58:43 +0800 Subject: ui/dmabuf: extend QemuDmaBuf to support multi-plane MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit mesa/radeonsi is going to support explicit modifier which may export a multi-plane texture. For example, texture with DCC enabled (a compressed format) has two planes, one with compressed data, the other with meta data for compression. v2: * change API qemu_dmabuf_get_fd/offset/stride to qemu_dmabuf_get_fds/offsets/strides. * change API qemu_dmabuf_dup_fd to qemu_dmabuf_dup_fds. * add an extra arg to these API for the length of the array.
