2018-02-09hwc2: null display mode supportVarun Arora
Adds null display support at HWC level. HWCDisplay will internally use DisplayNull object as display_intf_ when in null display mode via sdm debug property Change-Id: I160caff9c354e23e6c5849b661dc3c3bf6c41d20 CRs-Fixed: 2186932
2018-01-29sdm: Fix refresh seqeunce for QDCM solid fill colorGopikrishnaiah Anandan
Calibration tool issues binder call to display solid fill color onto screen for calibration. Acquire scope lock to ensure that there is no race condition between binder thread and display thread w.r.t solid fill color. Block the solid fill binder call with a delay to ensure that solid fill color is displayed. Change-Id: Ic0ee320e24dc662213531362b124ff7bbfdf4309

2017-12-18hwc2: Add missing locks, relax some locksSaurabh Shah
Currently calls forwarded to CallDisplayFunction and CallLayerFunction are not protected via a lock, causing races. Add scope lock. Relax sequence locks in SetPowerMode, Dumpsys and Create/Destroy layer to scope locks to avoid locks ups in cases where these get called from the same binder thread that called Validate.

2017-11-16sdm: Reset needs_validate_ when SurfaceFlinger shutdownBaldev Sahu
Composer keeps on calling refresh if this flag is set to true and SurfaceFlinger can not reconnect to it after restart. So clear this flag in case it is left set when sf goes down. Change-Id: I65119d567c0a3b65df22f10067993e39d8426523
2017-11-15sdm: Fix SDM Dump() design and synchronization issuesSaurabh Shah
SDM Dump() follows a DumpImpl based design that prevent it from being called via a lock held from HWC. This leads to synchronization issues since SDM's Dump() method accesses original layer stack members. This change removes the unnecessary DumpImpl based design and routes the flow to SDM's Dump() method with HWC's Dump() method. Change-Id: I9f255c061a2509a4e9d8c6bd446389df3e8f6549 CRs-fixed: 2139697

Create layer stack with test layer and ignore all layers from the SF framework. 4. Generate the pattern with 18/24/30 bpp based on pattern type and bpp read from sysfs node and send it to DP interface. 5. Add support to calculate CRC to validate the color pattern.

2017-10-02hwc: Fix locking on event handling and validation stateSaurabh Shah
Fix a small gap in locking on event handling where validation state was reset after lock scope was over. Also validation state was being reset for all displays even if event was for primary. This is incorrect since lock was only held for primary. Move validation state reset to be per display Change-Id: I24a8930d536a906d2b8adba35833774c03b59933 CRs-fixed: 1114808

Add per display granular locking in HWC to align with the Validate, Present call sequence from SF, that happens independently for each display and possibly on different threads.

2017-08-09sdm: hwc2: Support Skip Validate featureSushil Chauhan
1. Set HWC2_CAPABILITY_SKIP_VALIDATE cap in GetCapabilities api. 2. If HWC2_CAPABILITY_SKIP_VALIDATE cap is exposed by HWC HAL, then SF just calls PresentDisplay api. It is the responsibility of HWC HAL to request for ValidateDisplay, if it is required. If the cap is not exposed by HWC HAL, then there will be ValidateDisplay call followed by PresentDisplay. 3. In case of Surface Damage update on a layer, SDM needs a Validate call to program SDE driver for Partial Update feature. 4. SDM needs Validate call to enter in safe Mode for use cases like Idle / Thermal fallback, HDMI and Virtual Connect/Disconnet, etc. 5. In case of layer buffer geometry, metadata or secure attributes change, SDM needs Validate call to program the SDE driver. 6. SDM needs Validate call if GPU tonemapping is required on a layer during HDR Video playback. 7. Read user defined underscan width and height, when the External display gets created and initialized. 8. SDM needs Validate call for few APIs which are exposed by the Binder Interface or by HWComposer APIs, since they need re-configuration of SDE driver or they modify Panel / LayerMixer / Display configuration. 9. The feature is enabled by default. "sdm.debug.disable_skip_validate" system property can be set to '1' to disable the feature. CRs-Fixed: 2071632 Change-Id: I68f0db3af16afa4ad4eb789cd1f6b12caf6381e4
2017-08-09hwc2: Handle corner and error conditions properly.Arun Kumar K.R
- Make changes as per the hwc2 header to return correct error codes. - Check for comp types in SetLayerColor and SetCursorPosition and error out if they are not as the expected. - As per the HWC2 header, SetCursorPosition cannot be called after validateDisplay, hence return error when its called after validate and before present. - Handle Create and Destroy Virtual Displays accordingly. - Includes 017ba1f and 5e5da2(partially) from lnx.3.9-rel.

2017-08-04hwc2: Wait for RegisterCallback() from SF before sending events.Ramkumar Radhakrishnan
Surfaceflinger registers callback functions to be called from hwcomposer on specific events like hotplug, vsync and screen refresh. since surfaceflinger and hwcomposer are two different processes that can run asynchronously. This causes hwcomposer to send an event to surfaceflinger before surfaceflinger registers callback and results in undefined behavior. So wait for callbacks to get registered by surfaceflinger and send an event to surfacelinger. Change-Id: I288e4d7dde8179cb4a119cdedad2877344c06dae CRs-Fixed: 2085392
