This is a note to let you know that I have just added a patch titled drm/radeon: properly set vm fragment size for TN/RL to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt7. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 6dc57e3c23f62a046b9d716de32a31b0f4380aa6 Mon Sep 17 00:00:00 2001 From: Alex Deucher <alexander.deucher@amd.com> Date: Fri, 30 Jan 2015 09:52:24 -0500 Subject: drm/radeon: properly set vm fragment size for TN/RL commit a124d068bf5be6be2ff4b9fab77b1b7509107e68 upstream. Should be the same as cayman. We don't use VM by default on NI parts so this isn't critical.
