panfrost: Crash when trying to use EGL_KHR_partial_update
I've been trying to implement EGL_KHR_partial_update on kwin_wayland using eglSetDamageRegionKHR and I've been getting consistently a crash when calling eglSetDamageRegionKHR(). In fact eglGetProcAddress("eglSetDamageRegionKHR") is returning NULL to me.
Since I assumed I was doing something wrong, I checked on weston and there it seems to have the same problem. See below. Could anyone help me see what's going wrong there?
