This is a note to let you know that I have just added a patch titled drm/cirrus: Invalidate page tables when pinning a BO to the linux-3.8.y-queue branch of the 3.8.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.8.y-queue This patch is scheduled to be released in version 3.8.13.7. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 4e94429cd04fe22a2e42d664dcb1b41b37710d42 Mon Sep 17 00:00:00 2001 From: Michal Srb <msrb@suse.com> Date: Tue, 6 Aug 2013 15:26:50 +0200 Subject: drm/cirrus: Invalidate page tables when pinning a BO commit 109a51598869a39fdcec2d49672a9a39b6d89481 upstream. This is a cirrus version of Egbert Eich's patch for mgag200. Without bo.bdev->dev_mapping set, the ttm_bo_unmap_virtual_locked called from ttm_bo_handle_move_mem returns with no effect. If any application accessed the memory before it was moved, it will access wrong memory next time. This causes crashes when changing resolution down.
