From 14156f82704dcf3ccd14b114eb168cc3ef018572 Mon Sep 17 00:00:00 2001 From: =?utf8?q?V=C3=ADctor=20Manuel=20J=C3=A1quez=20Leal?= Date: Thu, 7 Oct 2021 21:51:55 +0200 Subject: [PATCH] va: Split VA memory handling in different files. Take out the VA memory wrappers from gstvallocator.c to an external file exposing the functions. This is going to be needed for the copy helper object.
