From f8a78d54d6f1a4d972cb3e9dfb3a1c59f8c32a45 Mon Sep 17 00:00:00 2001 From: Andrei Gherzan Date: Thu, 12 Jul 2012 17:45:40 +0300 Subject: [PATCH] image_types.bbclass: Add XZ variable to set number of threads to be used while compressing Default this variable to 0. This will make xz use as many threads as there are CPU cores on the system.
