drm/i915/flipq: Provide the nuts and bolts code for flip queue
Provide the lower level code for PIPEDMC based flip queue.
We'll use the so called semi-full flip queue mode where the
PIPEDMC will start the provided DSB on a scanline a little
ahead of the vblank. We need to program the triggering scanline
early enough so that the DSB has enough time to complete writing
all the double buffered registers before they get latched (at
start of vblank).
The firmware implements several queues:
- 3 "plane queues" which execute a single DSB per entry
- 1 "general queue" which can apparently execute 2 DSBs per entry
- 1 vestigial "fast queue" that replaced the "simple flip queue"
on ADL+, but this isn't supposed to be used due to issues.
But we only need a single plane queue really, and we won't actually
use it as a real queue because we don't allow queueing multiple commits
ahead of time. So the whole thing is perhaps useless. I suppose
there migth be some power saving benefits if we would get the flip
scheduled by userspace early and then could keep some hardware powered
off a bit longer until the DMC kicks off the flipq programming. But that
is pure speculation at this time and needs to be proven.
The code to hook up the flip queue into the actual atomic commit
path will follow later.
TODO: need to think how to do the "wait for DMC firmware load" nicely
need to think about VRR and PSR
etc.
v2: Don't write DMC_FQ_W2_PTS_CFG_SEL on pre-lnl
Don't oops at flipq init if there is no dmc
v3: Adapt to PTL+ flipq changes (different queue entry
layout, different trigger event, need VRR TG)
Use the actual CDCLK frequency
Ask the DSB code how long things are expected to take
v3: Adjust the cdclk rounding (docs are 100% vague, Windows
rounds like this)
Initialize some undocumented magic DMC variables on PTL
v4: Use PIPEDMC_FQ_STATUS for busy check (the busy bit in
PIPEDMC_FQ_CTRL is apparently gone on LNL+)
Based the preempt timeout on the max exec time
Preempt before disabling the flip queue
Order the PIPEDMC_SCANLINECMP* writes a bit more carefully
Fix some typos
v5: Try to deal with some clang-20 div-by-zero false positive (Nathan)
Add some docs (Jani)

drm/gpusvm, drm/pagemap: Move migration functionality to drm_pagemap
The migration functionality and track-keeping of per-pagemap VRAM mapped to the CPU mm is not per GPU_vm, but rather per pagemap. This is also reflected by the functions not needing the drm_gpusvm structures. So move to drm_pagemap. With this, drm_gpusvm shouldn't really access the page zone-device-data since its meaning is internal to drm_pagemap. Currently it's used to reject mapping ranges backed by multiple drm_pagemap allocations. For now, make the zone-device-data a void pointer. Alter the interface of drm_gpusvm_migrate_to_devmem() to ensure we don't pass a gpusvm pointer. Rename CONFIG_DRM_XE_DEVMEM_MIRROR to CONFIG_DRM_XE_PAGEMAP. Matt is listed as author of this commit since he wrote most of the code, and it makes sense to retain his git authorship. Thomas mostly moved the code around. v3: - Kerneldoc fixes (CI) - Don't update documentation about how the drm_pagemap migration should be interpreted until upcoming patches where the functionality is implemented. (Matt Brost) v4: - More kerneldoc fixes around timeslice_ms (Himal Ghimiray, Matt Brost) v6: - Fix an uninitialized pagemap pointer (CI) Co-developed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Link: https://lore.kernel.org/r/20250619134035.170086-2-thomas.hellstrom@linux.intel.com |

gpu: nova-core: update and annotate TODO list
A few new dependencies are required to remove some of the TODO items: - A way to safely convert from byte slices to types implementing `FromBytes`, - A way to obtain slices and write into a `CoherentAllocation`, - Several improvements to the `register!()` macro, - Alignment operations to powers of two, and an equivalent to the C `fls`, - Support for `xa_alloc` in the XAlloc bindings. Some items have also become obsolete: - The auxiliary bus abstractions have been implemented and are in use, - The ELF utilities are not considered for being part of the core kernel bindings anymore. - VBIOS, falcon and GPU timer have been completed. We now have quite a few TODO entries in the code, so annotate them with a 4 letter code representing the corresponding task in `todo.rst`. This allows to easily find which part of the code corresponds to a given entry (and conversely).

The other big NVIDIA related one is nouveau adds support for Hopper/Blackwell GPUs, this required a new GSP firmware update to 570.144, and a bunch of rework in order to support multiple fw interfaces. There is also the introduction of an asahi uapi header file as a precursor to getting the real driver in later, but to unblock userspace mesa packages while the driver is trapped behind rust enablement.

drm/doc: Document some tracepoints as uAPI
This commit adds a document section in drm-uapi.rst about tracepoints, and mark the events gpu_scheduler_trace.h as stable uAPI. The goal is to explicitly state that tools can rely on the fields, formats and semantics of these events.

drm/xe: Make xe_gt_freq part of the Documentation
The documentation was created with the creation of the component,
however it has never been actually shown in the actual Documentation.
While doing this, fixes the identation style, to avoid new warnings

Documentation/gpu: Disambiguate SPI term
Documentation/userspace-api/media/glossary.rst:170: WARNING: duplicate term description of SPI, other instance in gpu/amdgpu/amdgpu-glossary
That's because SPI of amdgpu (Shader Processor Input) shares the same
global glossary term as SPI of media subsystem (which is Serial
Peripheral Interface Bus). Disambiguate the former from the latter to
fix the warning.
Note that adding context qualifiers in the term is strictly necessary
in order to make Sphinx happy.

gpu: nova-core: define registers layout using helper macro
Add the register!() macro, which defines a given register's layout and provide bit-field accessors with a way to convert them to a given type. This macro will allow us to make clear definitions of the registers and manipulate their fields safely. The long-term goal is to eventually move it to the kernel crate so it can be used by other drivers as well, but it was agreed to first land it into nova-core and make it mature there. To illustrate its usage, use it to define the layout for the Boot0 (renamed to NV_PMC_BOOT_0 to match OpenRM's naming scheme) and take advantage of its accessors.

drm: Add UAPI for the Asahi driver
This adds the UAPI for the Asahi driver targeting the GPU in the Apple M1 and M2 series systems on chip. The UAPI design is based on other modern Vulkan-capable drivers, including Xe and Panthor. Memory management is based on explicit VM management. Synchronization is exclusively explicit sync. This UAPI is validated against our open source Mesa stack, which is fully conformant to the OpenGL 4.6, OpenGL ES 3.2, OpenCL 3.0, and Vulkan 1.4 standards. The Vulkan driver supports sparse, exercising the VM_BIND mechanism. This patch adds the standalone UAPI header. It is implemented by an open source DRM driver written in Rust. We fully intend to upstream this driver when possible. However, as a production graphics driver, it depends on a significant number of Rust abstractions that will take a long time to upstream. In the mean time, our userspace is upstream in Mesa but is not allowed to probe with upstream Mesa as the UAPI is not yet reviewed and merged in the upstream kernel. Although we ship a patched Mesa in Fedora Asahi Remix, any containers shipping upstream Mesa builds are broken for our users, including upstream Flatpak and Waydroid runtimes. Additionally, it forces us to maintain forks of Mesa and virglrenderer, which complicates bisects. The intention in sending out this patch is for this UAPI to be thoroughly reviewed. Once we as the DRM community are satisfied with the UAPI, this header lands signifying that the UAPI is stable and must only be evolved in backwards-compatible ways; it will be the UAPI implemented in the DRM driver that eventually lands upstream. That promise lets us enable upstream Mesa, solving all these issues while the upstream Rust abstractions are developed. https://github.com/alyssarosenzweig/linux/commits/agx-uapi-v7 contains the DRM driver implementing this proposed UAPI. https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33984 contains the Mesa patches to implement this proposed UAPI. That Linux and Mesa branch together give a complete graphics/compute stack on top of this UAPI.
