amdgpu_dm_atomic_check() is used to validate the entire configuration of
planes and crtc's that the user space wants to commit.
However amdgpu_dm_atomic_check() depends upon DRM_MODE_ATOMIC_ALLOW_MODESET
flag else its mostly dummy.
Its not mandatory for the user space to set DRM_MODE_ATOMIC_ALLOW_MODESET,
and in general its not set either along with DRM_MODE_ATOMIC_TEST_ONLY.
Considering its importantance, this patch defers the allow_modeset check
in dm_update_planes_state(), so that there shall be scope to validate
the configuration sent from user space, without impacting the population
of dc/dm related data structures.

Errors while developing the patch to create of_overlay_fdt_apply()
exposed inadequate error messages to debug problems when overlay
devicetree fragment nodes contain an invalid target path. Improve
the messages in find_target_node() to remedy this.
Signed-off-by: Frank Rowand <frank.rowand@sony.com>
The unittest-data overlays have been pulled into proper overlay
devicetree source files without changing their format. The
next step is to convert them to use sugar syntax instead of
hand coding overlay fragments structure.
A few of the overlays can not be converted because they test
absolute target paths in the overlay fragment. dtc does not
generate this type of target:
overlay_0.dts
overlay_1.dts
overlay_12.dts
overlay_13.dts
Two pre-existing unittest overlay devicetree source files are
also converted:
overlay_bad_phandle.dts
overlay_bad_symbol.dts
Signed-off-by: Frank Rowand <frank.rowand@sony.com>
Move duplicating and unflattening of an overlay flattened devicetree
(FDT) into the overlay application code. To accomplish this,
of_overlay_apply() is replaced by of_overlay_fdt_apply().
The copy of the FDT (aka "duplicate FDT") now belongs to devicetree
code, which is thus responsible for freeing the duplicate FDT. The
caller of of_overlay_fdt_apply() remains responsible for freeing the
original FDT.
The unflattened devicetree now belongs to devicetree code, which is
thus responsible for freeing the unflattened devicetree.
These ownership changes prevent early freeing of the duplicated FDT
or the unflattened devicetree, which could result in use after free
errors.
of_overlay_fdt_apply() is a private function for the anticipated
overlay loader.
Update unittest.c to use of_overlay_fdt_apply() instead of
of_overlay_apply().
Move overlay fragments from artificial locations in
drivers/of/unittest-data/tests-overlay.dtsi into one devicetree
source file per overlay. This led to changes in
drivers/of/unitest-data/Makefile and drivers/of/unitest.c.
- Add overlay directives to the overlay devicetree source files so
that dtc will compile them as true overlays into one FDT data
chunk per overlay.
- Set CFLAGS for drivers/of/unittest-data/testcases.dts so that
symbols will be generated for overlay resolution of overlays
that are no longer artificially contained in testcases.dts
- Unflatten and apply each unittest overlay FDT using
of_overlay_fdt_apply().
- Enable the of_resolve_phandles() check for whether the unflattened
overlay is detached. This check was previously disabled because the
overlays from tests-overlay.dtsi were not unflattened into detached
trees.
- Other changes to unittest.c infrastructure to manage multiple test
FDTs built into the kernel image (access by name instead of
arbitrary number).
- of_unittest_overlay_high_level(): previously unused code to add
properties from the overlay_base devicetree to the live tree
was triggered by the restructuring of tests-overlay.dtsi and thus
testcases.dts. This exposed two bugs: (1) the need to dup a
property before adding it, and (2) property 'name' is
auto-generated in the unflatten code and thus will be a duplicate
in the __symbols__ node - do not treat this duplicate as an error.

x86_flattree_get_config() is incorrectly protected by
ifdef CONFIG_OF_FLATTREE. It uses of_get_flat_dt_size(), which
only exists if CONFIG_OF_EARLY_FLATTREE. This issue has not
been exposed previously because OF_FLATTREE did not occur unless
it was selected by OF_EARLY_FLATTREE. A devicetree overlay change
is selecting OF_FLATTREE directly instead of indirectly enabling
it by selecting OF_EARLY_FLATTREE.
This problem was exposed by a randconfig generated by the kbuild
test robot, where Platform OLPC was enabled. OLPC selects
OF_PROMTREE instead of OF_EARLY_FLATREE. The only other x86
platform that selects OF is X86_INTEL_CE, which does select
OF_EARLY_FLATTREE.
