Code Releases Activity

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>``
AMDgpu Display Manager

TTM_GLOBAL_TTM_BO, and its size should be sizeof(struct
ttm_bo_global). Again, driver-specific init and release functions may
be provided, likely eventually calling ttm_bo_global_init() and
ttm_bo_global_release(), respectively. Also, like the previous

count for the TTM, which will call your initialization function.

/**
* 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().
*
* To expose DC's hardware interrupt toggle to the base driver, DM implements
* &amdgpu_irq_src_funcs.set hooks. Base driver calls it through
* amdgpu_irq_update() to enable or disable the interrupt.
