DMX -- Settles $1M Child Support Case With Baby Mama

DMX just settled a HUGE $1 million child support case ... and TMZ has learned he's now in Europe trying to recoup some of that cash.

TMZ broke the story ... DMX was accused of owing more than 10 years of back child support to Patricia Trejo. Because he owed so much ... X wasn't allowed to have a passport ... which meant he was prohibited from traveling to any overseas gigs.

DMX's rep tells TMZ the child support case has now been settled -- he wouldn't say for how much but we're told X paid off a huge chunk.
