2015-06-19NVMe: Fix IO for extended metadata formatsKeith Busch
This fixes io submit ioctl handling when using extended metadata formats. When these formats are used, the user provides a single virtually contiguous buffer containing both the block and metadata interleaved, so the metadata size needs to be added to the total length and not mapped as a separate transfer. The command is also driver generated, so this patch does not enforce blk-integrity extensions provide the metadata buffer.

2015-06-19perf tools: Ensure thread-stack is flushedAdrian Hunter
The thread-stack represents a thread's current stack. When a thread exits there can still be many functions on the stack e.g. exit() can be called many levels deep, so all the callers will never return. To get that information output, the thread-stack must be flushed. Previously it was assumed the thread-stack would be flushed when the struct thread was deleted. With thread ref-counting it is no longer clear when that will be, if ever. So instead explicitly flush all the thread-stacks at the end of a session.

2015-06-20drm/exynos: initialize VIDCON0 when fimd is disabledJoonyoung Shim
When the fimd is disabled by fimd_disable(), enabled overlay layers also are disabled. If clocks for fimd are enabled by fimd_enable() on this case, it can lead IOMMU page fault. The reason is that VIDCON0_ENVID and VIDCON0_ENVID_F bits of VIDCON0 register are set still even though fimd is disabled, so it may continue display output of prior when clocks for fimd are enabled again.

2015-06-20drm/exynos: remove chained calls to enableJoonyoung Shim
With atomic modesetting all the control for CRTC, Planes, Encoders and Connectors should come from DRM core, so the driver is not allowed to enable or disable planes from inside the crtc_enable()/disable() call. But it needs to disable planes with crtc_disable in exynos driver internally. Because crtc is disabled before plane is disabled, it means plane_disable just returns without any register changes, then we cannot be sure setting register to disable plane when crtc is disable. This patch removes this chainned calls to enable plane from exynos hw drivers code letting only DRM core touch planes except to disable plane. Also it leads eliminable enabled and resume of struct exynos_drm_plane.

It is possible because the function checks only whether DSI is initialized or not, and there is a moment which DSI is set by uninitialized, but DSI is still turning down. To prevent it, DSI must be set by disabled before starting to be turned down, and exynos_dsi_host_transfer() must check whether DSI is enabled or not.

2015-06-20drm/exynos: fix broken component binding in case of multiple pipelinesAndrzej Hajda
In case there are multiple pipelines and deferred probe occurs, only components of the first pipeline were bound. As a result only one pipeline was available. The main cause of this issue was dynamic generation of component match table - every component driver during probe registered itself on helper list, if there was at least one pipeline present on this list component match table were created without deferred components. This patch removes this helper list, instead it creates match table from existing devices requiring exynos_drm KMS drivers. This way match table do not depend on probe/deferral order and contains all KMS components. As a side effect patch makes the code cleaner and significantly smaller.

2015-06-20drm/exynos: remove exported functions from exynos_drm_planeGustavo Padovan
Now that no one is using the functions exported by exynos_drm_plane due to the atomic conversion we can make remove some of the them or make them static. v2: remove unused exynos_drm_crtc v3: fix checkpatch error (reported by Joonyoung) Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Reviewed-by: Joonyoung Shim <jy0922.shim@samsung.com> Tested-by: Tobias Jakobi <tjakobi@math.uni-bielefeld.de> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2015-06-20drm/exynos: atomic phase 3: convert page flipsGustavo Padovan
PageFlips now use the atomic helper to work through the atomic modesetting API. Async page flips are not supported yet. v2: Add .atomic_begin() step to handle the vblank part we removed from exynos page_flip code.
