From b2200514af1ce22da9b0dcc0ca5e24731badd192 Mon Sep 17 00:00:00 2001 From: Alex Villacís Lasso Date: Sun, 12 May 2019 20:34:28 -0500 Subject: gbm: gbm_bo_get_handle_for_plane fallback to nonplanar handle MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit f9567ab435217a72cbae628336ead84dc0b2a803 (gbm: Export a getter for per plane handles) contains an API version check that fails on i915 (API version 7 vs. check for minimum API version 13). Any client that migrates to the planar API will start failing on i915 (see https://gitlab.gnome.org/GNOME/mutter/issues/127 for mutter, and https://bugs.freedesktop.org/show_bug.cgi?id=108487 for weston). This commit adds a fallback for plane 0 when the API check fails and returns the non-planar handle in this scenario, making the call equivalent to gbm_bo_get_handle(). This is enough for weston 6.0.0 to start working again on an i915 system.
