Merge tag 'drm-next-2020-01-30' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Davbe Airlie: "This is the main pull request for graphics for 5.6. Usual selection of changes all over. I've got one outstanding vmwgfx pull that touches mm so kept it separate until after all of this lands. I'll try and get it to you soon after this, but it might be early next week (nothing wrong with code, just my schedule is messy) This also hits a lot of fbdev drivers with some cleanups. Other notables: - vulkan timeline semaphore support added to syncobjs - nouveau turing secureboot/graphics support - Displayport MST display stream compression support Detailed summary: uapi: - dma-buf heaps added (and fixed) - command line add support for panel oreientation - command line allow overriding penguin count drm: - mipi dsi definition updates - lockdep annotations for dma_resv - remove dma-buf kmap/kunmap support - constify fb_ops in all fbdev drivers - MST fix for daisy chained hotplug- - CTA-861-G modes with VIC >= 193 added - fix drm_panel_of_backlight export - LVDS decoder support - more device based logging support - scanline alighment for dumb buffers - MST DSC helpers scheduler: - documentation fixes - job distribution improvements panel: - Logic PD type 28 panel support - Jimax8729d MIPI-DSI - igenic JZ4770 - generic DSI devicetree bindings - sony acx424AKP panel - Leadtek LTK500HD1829 - xinpeng XPP055C272 - AUO B116XAK01 - GiantPlus GPM940B0 - BOE NV140FHM-N49 - Satoz SAT050AT40H12R2 - Sharp LS020B1DD01D panels. ttm: - use blocking WW lock i915: - hw/uapi state separation - Lock annotation improvements - selftest improvements - ICL/TGL DSI VDSC support - VBT parsing improvments - Display refactoring - DSI updates + fixes - HDCP 2.2 for CFL - CML PCI ID fixes - GLK+ fbc fix - PSR fixes - GEN/GT refactor improvments - DP MST fixes - switch context id alloc to xarray - workaround updates - LMEM debugfs support - tiled monitor fixes - ICL+ clock gating programming removed - DP MST disable sequence fixed - LMEM discontiguous object maps - prefaulting for discontiguous objects - use LMEM for dumb buffers if possible - add LMEM mmap support amdgpu: - enable sync object timelines for vulkan - MST atomic routines - enable MST DSC support - add DMCUB display microengine support - DC OEM i2c support - Renoir DC fixes - Initial HDCP 2.x support - BACO support for Arcturus - Use BACO for runtime PM power save - gfxoff on navi10 - gfx10 golden updates and fixes - DCN support on POWER - GFXOFF for raven1 refresh - MM engine idle handlers cleanup - 10bpc EDP panel fixes - renoir watermark fixes - SR-IOV fixes - Arcturus VCN fixes - GDDR6 training fixes - freesync fixes - Pollock support amdkfd: - unify more codepath with amdgpu - use KIQ to setup HIQ rather than MMIO radeon: - fix vma fault handler race - PPC DMA fix - register check fixes for r100/r200 nouveau: - mmap_sem vs dma_resv fix - rewrite the ACR secure boot code for Turing - TU10x graphics engine support (TU11x pending) - Page kind mapping for turing - 10-bit LUT support - GP10B Tegra fixes - HD audio regression fix hisilicon/hibmc: - use generic fbdev code and helpers rockchip: - dsi/px30 support virtio: - fb damage support - static some functions vc4: - use dma_resv lock wrappers msm: - use dma_resv lock wrappers - sc7180 display + DSI support - a618 support - UBWC support improvements vmwgfx: - updates + new logging uapi exynos: - enable/disable callback cleanups etnaviv: - use dma_resv lock wrappers atmel-hlcdc: - clock fixes mediatek: - cmdq support - non-smooth cursor fixes - ctm property support sun4i: - suspend support - A64 mipi dsi support rcar-du: - Color management module support - LVDS encoder dual-link support - R8A77980 support analogic: - add support for an6345 ast: - atomic modeset support - primary plane garbage fix arcgpu: - fixes for fourcc handling tegra: - minor fixes and improvments mcde: - vblank support meson: - OSD1 plane AFBC commit gma500: - add pageflip support - reomve global drm_dev komeda: - tweak debugfs output - d32 support - runtime PM suppotr udl: - use generic shmem helpers - cleanup and fixes" * tag 'drm-next-2020-01-30' of git://anongit.freedesktop.org/drm/drm: (1998 commits) drm/nouveau/fb/gp102-: allow module to load even when scrubber binary is missing drm/nouveau/acr: return error when registering LSF if ACR not supported drm/nouveau/disp/gv100-: not all channel types support reporting error codes drm/nouveau/disp/nv50-: prevent oops when no channel method map provided drm/nouveau: support synchronous pushbuf submission drm/nouveau: signal pending fences when channel has been killed drm/nouveau: reject attempts to submit to dead channels drm/nouveau: zero vma pointer even if we only unreference it rather than free drm/nouveau: Add HD-audio component notifier support drm/nouveau: fix build error without CONFIG_IOMMU_API drm/nouveau/kms/nv04: remove set but not used variable 'width' drm/nouveau/kms/nv50: remove set but not unused variable 'nv_connector' drm/nouveau/mmu: fix comptag memory leak drm/nouveau/gr/gp10b: Use gp100_grctx and gp100_gr_zbc drm/nouveau/pmu/gm20b,gp10b: Fix Falcon bootstrapping drm/exynos: Rename Exynos to lowercase drm/exynos: change callback names drm/mst: Don't do atomic checks over disabled managers drm/amdgpu: add the lost mutex_init back drm/amd/display: skip opp blank or unblank if test pattern enabled ...

-/*
- * The struct nvkm_msgqueue (named so for lack of better candidate) manages
- * a firmware (typically, NVIDIA signed firmware) running under a given falcon.
- *
- * Such firmwares expect to receive commands (through one or several command
- * queues) and will reply to such command by sending messages (using one
- * message queue).
- *
- * Each firmware can support one or several units - ACR for managing secure
- * falcons, PMU for power management, etc. A unit can be seen as a class to
- * which command can be sent.
- *
- * One usage example would be to send a command to the SEC falcon to ask it to
- * reset a secure falcon. The SEC falcon will receive the command, process it,
- * and send a message to signal success or failure. Only when the corresponding
- * message is received can the requester assume the request has been processed.
- *
- * Since we expect many variations between the firmwares NVIDIA will release
- * across GPU generations, this library is built in a very modular way. Message
- * formats and queues details (such as number of usage) are left to
- * specializations of struct nvkm_msgqueue, while the functions in msgqueue.c
- * take care of posting commands and processing messages in a fashion that is
- * universal.
