From 95d40e8a28c722429c9e1fd73084faa2e9fef8ea Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Thu, 19 Dec 2019 21:47:43 -0800 Subject: [PATCH] kmsdrm: Fix busy-loop within libc's dlopen() For some obscure reason, the order in which the libdrm/libgbm libraries are loaded matters. Without this fix, the first call to check_modesetting() will work and load then unload all symbols properly, but the second call to this function will lock up as soon as dlopen() is called on libdrm. Swapping the order in which the libdrm and libgbm libraries are loaded is enough to fix (or work around?) this issue.
