This is a note to let you know that I have just added a patch titled radeon: Fix VCE ring test for Big-Endian systems to the linux-4.2.y-queue branch of the 4.2.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-4.2.y-queue This patch is scheduled to be released in version 4.2.8-ckt2. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 4.2.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ---8<------------------------------------------------------------ From 6c8402d0a0252330dae9b3beae9be18dc6711d88 Mon Sep 17 00:00:00 2001 From: Oded Gabbay <oded.gabbay@gmail.com> Date: Fri, 4 Dec 2015 23:09:04 +0200 Subject: radeon: Fix VCE ring test for Big-Endian systems MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 687f4b98d1f4e27508f7ad4bcce787c1ba58b289 upstream. This patch fixes the VCE ring test when running on Big-Endian machines. Every write to the ring needs to be translated to little-endian.
