      drm: Update edid-derived drm_display_info fields at edid property set [v2] · 4b4df570
      由 Keith Packard 提交于 
      There are a set of values in the drm_display_info structure for each
connector which hold information derived from EDID. These are computed
in drm_add_display_info. Before this patch, that was only called in
drm_add_edid_modes. This meant that they were only set when EDID was
present and never reset when EDID was not, as happened when the
display was disconnected.

One of these fields, non_desktop, is used from
drm_mode_connector_update_edid_property, the function responsible for
assigning the new edid value to the application-visible property.

Various drivers call these two functions (drm_add_edid_modes and
drm_mode_connector_update_edid_property) in different orders. This
means that even when EDID is present, the drm_display_info fields may
not have been computed at the time that
drm_mode_connector_update_edid_property used the non_desktop value to
set the non_desktop property.

I've added a public function (drm_reset_display_info) that resets the
drm_display_info field values to default values and then made the
drm_add_display_info function public. These two functions are now
called directly from drm_mode_connector_update_edid_property so that
the drm_display_info fields are always computed from the current EDID
information before being used in that function.

This means that the drm_display_info values are often computed twice,
once when the EDID property it set and a second time when EDID is used
to compute modes for the device. The alternative would be to uniformly
ensure that the values were computed once before being used, which
would require that all drivers reliably invoke the two paths in the
same order. The computation is inexpensive enough that it seems more
maintainable in the long term to simply compute them in both paths.

The API to drm_add_display_info has been changed so that it no longer
takes the set of edid-based quirks as a parameter. Rather, it now
computes those quirks itself and returns them for further use by
drm_add_edid_modes.

This patch also includes a number of 'const' additions caused by
drm_mode_connector_update_edid_property taking a 'const struct edid *'
parameter and wanting to pass that along to drm_add_display_info.

v2: after review by Daniel Vetter <daniel.vetter@ffwll.ch>

	Removed EXPORT_SYMBOL_GPL for drm_reset_display_info and
	drm_add_display_info.

	Added FIXME in drm_mode_connector_update_edid_property about
	potentially merging that with drm_add_edid_modes to avoid
	the need for two driver calls.

      drm/bridge: analogix dp: Fix runtime PM state in get_modes() callback · 510353a6
      由 Marek Szyprowski 提交于 
      get_modes() callback might be called asynchronously from the DRM core and
it is not synchronized with bridge_enable(), which sets proper runtime PM
state of the main DP device. Fix this by calling pm_runtime_get_sync()
before calling drm_get_edid(), which in turn calls drm_dp_i2c_xfer() and
analogix_dp_transfer() to ensure that main DP device is runtime active
when doing any access to its registers.

This fixes the following kernel issue on Samsung Exynos5250 Snow board:

      drm/vc4: Fix false positive WARN() backtrace on refcount_inc() usage · 5bfd4013
      由 Boris Brezillon 提交于 
      With CONFIG_REFCOUNT_FULL enabled, refcount_inc() complains when it's
passed a refcount object that has its counter set to 0. In this driver,
this is a valid use case since we want to increment ->usecnt only when
the BO object starts to be used by real HW components and this is
definitely not the case when the BO is created.

Fix the problem by using refcount_inc_not_zero() instead of
refcount_inc() and fallback to refcount_set(1) when
refcount_inc_not_zero() returns false. Note that this 2-steps operation
is not racy here because the whole section is protected by a mutex
which guarantees that the counter does not change between the
refcount_inc_not_zero() and refcount_set() calls.

      drm/exynos: remove unnecessary function declaration · 1cd6ae35
      由 Inki Dae 提交于 
      Removed exynos_drm_get_dma_device funtion declaration on top
of exynos_drm_drv.c file.

We can remove this declaration by moving the implementation
of this function upwards.

      drm/exynos: gem: Drop NONCONTIG flag for buffers allocated without IOMMU · 120a264f
      由 Marek Szyprowski 提交于 
      When no IOMMU is available, all GEM buffers allocated by Exynos DRM driver
are contiguous, because of the underlying dma_alloc_attrs() function
provides only such buffers. In such case it makes no sense to keep
BO_NONCONTIG flag for the allocated GEM buffers. This allows to avoid
failures for buffer contiguity checks in the subsequent operations on GEM
objects.

      drm/exynos: Fix dma-buf import · 89452d4a
      由 Marek Szyprowski 提交于 
      When IOMMU support was enabled, dma-buf import in Exynos DRM was broken
since commit f43c3596 ("drm/exynos: use real device for DMA-mapping
operations") due to using wrong struct device in drm_gem_prime_import()
function. This patch fixes following kernel BUG caused by incorrect buffer
mapping to DMA address space:
