drm/amdgpu: fix DP mode validation

2016-05-12T19:03:49Z

Switch the order of the loops to walk the rates on the top so we exhaust all DP 1.1 rate/lane combinations before trying DP 1.2 rate/lane combos. This avoids selecting rates that are supported by the monitor, but not the connector leading to valid modes getting rejected. bug: https://bugs.freedesktop.org/show_bug.cgi?id=95206 Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/amdgpu: set metadata pointer to NULL after freeing.

2016-05-03T15:53:44Z

Without this there was a double free of the metadata, which ended up freeing the fd table for me here, and taking out the machine more often than not. I reproduced with X.org + modesetting DDX + latest llvm/mesa, also required using dri3. Cc: stable@vger.kernel.org Reviewed-by: Christian König Signed-off-by: Dave Airlie Signed-off-by: Alex Deucher

drm/amdgpu: forbid mapping of userptr bo through radeon device file

2016-04-22T00:03:47Z

Allowing userptr bo which are basicly a list of page from some vma (so either anonymous page or file backed page) would lead to serious corruption of kernel structures and counters (because we overwrite the page->mapping field when mapping buffer). This will already block if the buffer was populated before anyone does try to mmap it because then TTM_PAGE_FLAG_SG would be set in in the ttm_tt flags. But that flag is check before ttm_tt_populate in the ttm vm fault handler. So to be safe just add a check to verify_access() callback.
