2018-03-05drm/amd/display: defer modeset check in dm_update_planes_stateShirish S
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.

2018-03-04of: convert unittest overlay devicetree source to sugar syntaxFrank Rowand
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>

2018-03-04of: change overlay apply input data from unflattened to FDTFrank Rowand
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.

2018-03-04x86: devicetree: fix config option around x86_flattree_get_config()Frank Rowand
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. Signed-off-by: Frank Rowand <frank.rowand@sony.com> Acked-by: Thomas Gleixner <tglx@linutronix.de>

2018-03-02drm/i915/execlists: Split spinlock from its irq disabling side-effectChris Wilson
During reset/wedging, we have to clean up the requests on the timeline and flush the pending interrupt state. Currently, we are abusing the irq disabling of the timeline spinlock to protect the irq state in conjunction to the engine's timeline requests, but this is accidental and conflates the spinlock with the irq state. A baffling state of affairs for the reader. Instead, explicitly disable irqs over the critical section, and separate modifying the irq state from the timeline's requests.
