Merge branch 'drm-next-4.21' of git://people.freedesktop.org/~agd5f/linux into drm-next

New features for 4.21:
amdgpu:
- Support for SDMA paging queue on vega
- Put compute EOP buffers into vram for better performance
- Share more code with amdkfd
- Support for scanout with DCC on gfx9
- Initial kerneldoc for DC
- Updated SMU firmware support for gfx8 chips
- Rework CSA handling for eventual support for preemption
- XGMI PSP support
- Clean up RLC handling
- Enable GPU reset by default on VI, SOC15 dGPUs
- Ring and IB test cleanups

amdkfd:
- Share more code with amdgpu

ttm:
- Move global init out of the drivers

scheduler:
- Track if schedulers are ready for work
- Timeout/fault handling changes to facilitate GPU recovery

+===================================
+drm/amd/display - Display Core (DC)
+===================================
+
+*placeholder - general description of supported platforms, what dc is, etc.*
+
+Because it is partially shared with other operating systems, the Display Core
+Driver is divided in two pieces.
+
+1. **Display Core (DC)** contains the OS-agnostic components. Things like
+   hardware programming and resource management are handled here.
+2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
+   amdgpu base driver and DRM are implemented here.
+
+It doesn't help that the entire package is frequently referred to as DC. But
+with the context in mind, it should be clear.
+
+When CONFIG_DRM_AMD_DC is enabled, DC will be initialized by default for
+supported ASICs. To force disable, set `amdgpu.dc=0` on kernel command line.
+Likewise, to force enable on unsupported ASICs, set `amdgpu.dc=1`.
+
+To determine if DC is loaded, search dmesg for the following entry:
+
+``Display Core initialized with <version number here>``

+/**
+ * DOC: overview
+ *
+ * DM provides another layer of IRQ management on top of what the base driver
+ * already provides. This is something that could be cleaned up, and is a
+ * future TODO item.
+ *
+ * The base driver provides IRQ source registration with DRM, handler
+ * registration into the base driver's IRQ table, and a handler callback
+ * amdgpu_irq_handler(), with which DRM calls on interrupts. This generic
+ * handler looks up the IRQ table, and calls the respective
+ * &amdgpu_irq_src_funcs.process hookups.
+ *
+ * What DM provides on top are two IRQ tables specifically for top-half and
+ * bottom-half IRQ handling, with the bottom-half implementing workqueues:
+ *
+ * - &amdgpu_display_manager.irq_handler_list_high_tab
+ * - &amdgpu_display_manager.irq_handler_list_low_tab
+ *
+ * They override the base driver's IRQ table, and the effect can be seen
+ * in the hooks that DM provides for &amdgpu_irq_src_funcs.process. They
+ * are all set to the DM generic handler amdgpu_dm_irq_handler(), which looks up
+ * DM's IRQ tables. However, in order for base driver to recognize this hook, DM
+ * still needs to register the IRQ with the base driver. See
+ * dce110_register_irq_handlers() and dcn10_register_irq_handlers().
+ *
