This is a note to let you know that I have just added a patch titled drm/mgag200: 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 300cbab082ee6c539afbde0df809b38fba40990e Mon Sep 17 00:00:00 2001 From: Egbert Eich <eich@suse.com> Date: Wed, 17 Jul 2013 17:40:56 +0200 Subject: drm/mgag200: Invalidate page tables when pinning a BO commit ecaac1c866bcda4780a963b3d18cd310d971aea3 upstream. When a BO gets pinned the placement may get changed. If the memory is mapped into user space and user space has already accessed the mapped range the page tables are set up but now point to the wrong memory. Set bo.mdev->dev_mapping in mgag200_bo_create() to make sure that ttm_bo_unmap_virtual() called from ttm_bo_handle_move_mem() will take care of this. v2: Don't call ttm_bo_unmap_virtual() in mgag200_bo_pin(), fix comment.
