Android sync driver solves this by having a separate CONFIG_SW_SYNC_USER that can be used for testing. Here's a simple test by Google: https://android.googlesource.com/platform/system/core/+/master/libsync/sync_test.c And this is their userspace wrapper lib: https://android.googlesource.com/platform/system/core/+/master/libsync/sync.c https://android.googlesource.com/platform/system/core/+/master/libsync/include/sync/sync.h Would that go to libdrm now...? > Aside: Will you be at XDC or linux p...
