Having a closer look such code exists already at [1]
if test -n "$with_gallium_drivers" -a "x$with_gallium_drivers" != xswrast; then
if test "x$enable_xvmc" = xauto -a "x$have_xvmc_platform" = xyes; then
PKG_CHECK_EXISTS([xvmc >= $XVMC_REQUIRED], [enable_xvmc=yes],
[enable_xvmc=no])
fi
...
fi
Thus auto-detection will disable xvmc and other VL state-trackers,
when no gallium drivers or swrast only is set.
Thus the NEED_GALLIUM_VL_WINSYS shortly afterwords is set to
no/disabled, and vl_winsys_dri.c et al is not build.
A random old checkout commit 7be26976b8e8bc34fa7d55550014197ed2af488f
seems happy with the following:
mkdir aa; cd aa;
../autogen.sh --enable-autotools \
--with-platforms=x11 \
--with-dri-drivers= \
--with-gallium-drivers=swrast \
--disable-glx \
--disable-dri3 \
--disable-gbm
Am I missing something?
