Pull drm updates from Dave Airlie: "This is the main drm pull request for the 5.1 merge window. The big changes I'd highlight are: - nouveau has HMM support now, there is finally an in-tree user so we can quieten down the rip it out people. - i915 now enables fastboot by default on Skylake+ - Displayport Multistream support has been refactored and should hopefully be more reliable. Core: - header cleanups aiming towards removing drmP.h - dma-buf fence seqnos to 64-bits - common helper for DP mst hotplug for radeon,i915,amdgpu + new refcounting scheme - MST i2c improvements - drm_syncobj_cb removal - ARM FB compression fourcc - P010 + P016 fourcc - allwinner tiled format modifier - i2c over aux I2C_M_STOP support - DRM_AUTH handling fixes TTM: - ref/unref renaming New driver: - ARM komeda display driver scheduler: - refactor mirror list handling - rework hw fence processing - 0 run queue entity fix bridge: - TI DS90C185 LVDS bridge - thc631lvdm83d bridge improvements - cadence + allwinner DSI ported to generic phy panels: - Sitronix ST7701 panel - Kingdisplay KD097D04 - LeMaker BL035-RGB-002 - PDA 91-00156-A0 - Innolux EE101IA-01D i915: - Enable fastboot by default on SKL+/VLV/CHV - Export RPCS configuration for ICL media driver - Coffelake PCI ID - CNL clocks setup fixes - ACPI/PMIC support for MIPI/DSI - Per-engine WA init for all engines - Shrinker locking fixes - Kerneldoc updates - Lots of ring improvements and reset fixes - Coffeelake GVT Support - VFIO GVT EDID Region support - runtime PM wakeref tracking - ILK->IVB primary plane enable delays - userptr mutex locking fixes - DSI fixes - LVDS/TV cleanups - HW readout fixes - LUT robustness fixes - ICL display and watermark fixes - gem mmap race fix amdgpu: - add scheduled dependencies interface - DCC on scanout surfaces - vega10/20 BACO support - Multiple IH rings on soc15 - XGMI locking fixes - DC i2c/aux cleanups - runtime SMU debug interface - Kexec improvmeents - SR-IOV fixes - DC freesync + ABM fixes - GDS fixes - GPUVM fixes - vega20 PCIE DPM switching fixes - Context priority handling fixes radeon: - fix missing break in evergreen parser nouveau: - SVM support via HMM msm: - QCOM Compressed modifier support exynos: - s5pv210 rotator support imx: - zpos property support - pending update fixes v3d: - cache flush improvments vc4: - reflection support - HDMI overscan support tegra: - CEC refactoring - HDMI audio fixes - Tegra186 prep work - SOR crossbar device tree fixes sun4i: - implicit fencing support - YUV and scalar support improvements - A23 support - tiling fixes atmel-hlcdc: - clipping and rotation property fixes qxl: - BO and PRIME improvements - generic fbdev emulation dw-hdmi: - HDMI 2.0 2160p - YUV420 ouput rockchip: - implicit fencing support - reflection proerties virtio-gpu: - use generic fbdev emulation tilcdc: - cpufreq vs crtc init fix rcar-du: - R8A774C0 support - D3/E3 RGB output routing fixes and DPAD0 support - RA87744 LVDS support bochs: - atomic and generic fbdev emulation - ID mismatch error on bochs load meson: - remove firmware fbs" * tag 'drm-next-2019-03-06' of git://anongit.freedesktop.org/drm/drm: (1130 commits) drm/amd/display: Use vrr friendly pageflip throttling in DC. drm/imx: only send commit done event when all state has been applied drm/imx: allow building under COMPILE_TEST drm/imx: imx-tve: depend on COMMON_CLK drm/imx: ipuv3-plane: add zpos property drm/imx: ipuv3-plane: add function to query atomic update status gpu: ipu-v3: prg: add function to get channel configure status gpu: ipu-v3: pre: add double buffer status readback drm/amdgpu: Bump amdgpu version for context priority override. drm/amdgpu/powerplay: fix typo in BACO header guards drm/amdgpu/powerplay: fix return codes in BACO code drm/amdgpu: add missing license on baco files drm/bochs: Fix the ID mismatch error drm/nouveau/dmem: use dma addresses during migration copies drm/nouveau/dmem: use physical vram addresses during migration copies drm/nouveau/dmem: extend copy function to allow direct use of physical addresses drm/nouveau/svm: new ioctl to migrate process memory to GPU memory drm/nouveau/dmem: device memory helpers for SVM drm/nouveau/svm: initial support for shared virtual memory drm/nouveau: prepare for enabling svm with existing userspace interfaces ...

drm: helper functions for hdcp2 seq_num to from u32

2019-02-15T17:56:35Z

Library functions for endianness are aligned for 16/32/64 bits. But hdcp sequence numbers are 24bits(big endian). So for their conversion to and from u32 helper functions are developed. v2: Comment is updated. [Daniel] Reviewed-by Uma.

drm: include types.h from drm_hdcp.h

drm_hdcp.h uses kernel integer types, make it self-contained by including linux/kernel.h. This prepares for dropping drmP.h from files including drm_hdcp.h.

drm/i915: Check for downstream topology errors

2018-01-18T22:56:02Z

HDCP compliant Repeaters can support max of 127 devices and max depth of 7 for downstream topology. If these max limits are exceeded, repeater will set the topology error flags MAX_CASCADE_EXCEEDED and/or MAX_DEVS_EXCEEDED in Bstatus followed by asserting READY/CP_IRQ for HDCP transmitter. This patch check for these error flags as soon as READY bit is asserted.

In preparation for implementing HDCP in i915, add some HDCP related register offsets and defines.
