2016-05-04drm/ttm: Fix TTM BO accountingFelix Kuehling1-3/+2
TTM BO accounting is out of sync with how memory is really allocated in ttm[_dma]_tt_alloc_page_directory. This resulted in excessive estimated overhead with many small allocations. ttm_dma_tt_alloc_page_directory makes a single allocation for three arrays: pages, DMA and CPU addresses. It uses drm_calloc_large, which uses kmalloc internally for allocations smaller than PAGE_SIZE. ttm_round_pot should be a good approximation of its memory usage both above and below PAGE_SIZE.

Ofc I promise just a few leftovers for drm-misc and somehow it's the biggest pull. But really mostly trivial stuff: - MAINTAINERS updates from Emil - rename async to nonblock in atomic_commit to avoid the confusion between nonblocking ioctl and async flip (= not vblank synced), from Maarten. Needs to be regened with newer drivers, but probably only after -rc1 to catch them all. - actually lockless gem_object_free, plus acked driver conversion patches. All the trickier prep stuff already is in drm-next. - Noralf's nice work for generic defio support in our fbdev emulation.

2016-05-04Revert "drm/i915: start adding dp mst audio"Lyude5-65/+8
Right now MST audio is causing too many kernel panics to really keep around in the kernel. On top of that, even after fixing said panics it's still basically non-functional (at least on all the setups I've tested it on). Revert until we have a proper solution for this. This reverts commit 3d52ccf52f2c51f613e42e65be0f06e4e6788093.

2016-05-04drm/i915/lvds: separate border enable readout from panel fitterJani Nikula2-3/+4
The LVDS border enable is independent from the panel fitter. Move the readout of the "border bits" from i9xx_get_pfit_config() to intel_lvds_get_config(), where it will be read if LVDS is enabled even if the panel fitter is not. This fixes the state checker warning: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in gmch_pfit.lvds_border_bits (expected 0x00008000, found 0x00000000) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: drm-intel-fixes@lists.freedesktop.org Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=87632 Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Tested-by: Sitsofe Wheeler <sitsofe@yahoo.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1461933243-2140-1-git-send-email-jani.nikula@intel.com (cherry picked from commit a0cbe6a3f1c0e86342965430b4a775b5d35b416b) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2016-05-04drm/i915: Update CDCLK_FREQ register on BDW after changing cdclk frequencyVille Syrjälä2-0/+4
Update CDCLK_FREQ on BDW after changing the cdclk frequency. Not sure if this is a late addition to the spec, or if I simply overlooked this step when writing the original code. This is what Bspec has to say about CDCLK_FREQ: "Program this field to the CD clock frequency minus one. This is used to generate a divided down clock for miscellaneous timers in display." And the "Broadwell Sequences for Changing CD Clock Frequency" section clarifies this further: "For CD clock 337.5 MHz, program 337 decimal. For CD clock 450 MHz, program 449 decimal. For CD clock 540 MHz, program 539 decimal. For CD clock 675 MHz, program 674 decimal."
