Hi, this series based on a previous work from Chris adds support for partial mapping. Two preparatory patches are needed: - set the vm_pgoff when mapping frame buffer objects - do not fail when the exact address of a VM node is not the same as the starting address due to the offset. Indeed I was receiving a negative offset at first. Igt tests have been sent to the igt mailing list.
