NAK
These bindings duplicate existing ones, do not follow any existing
standards (wrong compatible) and are written completely different than
any other binding, which means you probably created big AI slop.
I'm not going to review this, it's quality is just beyond basic
standards. Sending something like this from Samsung means you do not
respect our time. You need to stay from scratch and read existing
documentation and existing bindings
I'll be organizing a mini meeting with Samsung on 13th Oct in Seoul,
feel free to join if you are around. I can explain then more why
wasting our time is making me very grumpy.
Best regards,
Krzysztof

Introduce the device‑tree entries for the Samsung Exynos AUTO V920
multimedia‑function controller (MFC). The patch defines:
- Reserved memory regions for firmware and CMA buffers.
- Core0 and Core1 memory mappings.
- The main MFC node with basic properties (compatible, reg, interrupts,
clocks, DMA window, firmware name, debug mode, etc.).
- Per‑core sub‑nodes (MFC‑0 and MFC‑1) with their own sysmmu,
firmware region, and configuration parameters.
- Resource table listing supported codecs and their capabilities.
Adds full support for the V920 MFC hardware to the mainline kernel
device‑tree, enabling proper memory allocation, interrupt handling and
codec operation on this platform.

This doesn't belong to media patchset, don't combine them.
Anyway, you completely disregarded DTS coding style and how we were
Samsung DTS. Please don't send us downstream code.
I won't be reviewing this, you need to start from scratch looming at
other recent code.
Remember also about Samsung maintainer profile, although with such
completely broken and non working bindings it's pointless now - this
code couldn't even be reliably tested with them.

This patch introduces the core data structures and debugging
infrastructure for the Samsung Exynos MFC (Multi‑Format Codec) driver.
mfc_data_struct.h
Defines all driver‑wide constants, enums, and structures required
for MFC core, contexts, buffers, QoS, and platform data.
Includes definitions for codec types, instance states, buffer usage,
logging options, feature flags, and hardware resources.
Provides the main struct mfc_dev, struct mfc_core, struct mfc_ctx,
and related helper structures.
mfc_debug.h
Implements a comprehensive set of debug macros (mfc_debug,
mfc_ctx_debug, mfc_core_debug, etc.) with configurable logging levels.
Adds error‑handling macros and trace utilities for device,
core, and context tracing.
Supports printing to the kernel log based on the
driver’s debugfs.logging_option settings.
These additions lay the groundwork for the MFC driver’s functionality,
enabling detailed logging, state tracking, and proper management of
codec resources.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
Introduce mfc_regs_mfc.h header
Define all MFC register addresses, including common, decoder,
encoder, and NAL queue registers.
Provide bit‑field masks and shifts for command/status registers,
codec types, error codes, and feature flags.
Add detailed comments for each register group and macro to
improve readability and maintainability.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
Introduce new driver headers: mfc_buf.h, mfc_common.h,
mfc_media.h, mfc_mem.h, mfc_regs.h, mfc_sched.h, and mfc_utils.h.
mfc_buf.h
Define buffer allocation/release APIs, common driver constants,
video node identifiers, and feature‑specific V4L2 control IDs.
mfc_common.h
Define driver metadata, node IDs, timeout values, format flags,
error/warning macros, and helper macros for buffer/context conversion
mfc_media.h
Expand V4L2 control IDs for a wide range of codec features (HEVC,
VP8/9, AV1, HDR, ROI, etc.)
mfc_mem.h
Implement memory management helpers for DMA buffers,
IOVA pool handling, and firmware mapping.
mfc_regs.h
Add register access macros for core, MMU, and PMU registers,
handling both 32‑bit and 64‑bit DMA address spaces.
mfc_sched.h
Supply scheduler helper for priority calculation and core initialization.
Supply utility inline functions for state changes,
interrupt flag handling, idle checking, and tracing.
mfc_utils.h
Provide inline utility functions for clearing interrupt flags,
state changes, operation‑mode updates, node‑type detection, and
idle‑checker management.
These changes collectively lay the groundwork for the Samsung MFC
(Multi‑Format Codec) driver, enabling buffer handling, register access,
and core scheduling functionalities.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
Introduce mfc_core_hw_reg_api.h with inline helpers for interrupt
handling, firmware status polling, pending checks, power control
(MFC on/off), and RISC start/stop.
Add mfc_debugfs.h exposing mfc_init_debugfs / mfc_deinit_debugfs
for kernel debugfs integration.
Provide mfc_core_reg_api.h containing version‑query macros and
interrupt‑status getters, plus debug‑control stubs.
Include necessary header dependencies.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
Introduce functions that define the core command interface, hardware‑lock
management, interrupt handling, and run‑time control for the MFC driver.
mfc_core_cmd.h
API for core initialization, power management,
instance lifecycle (open/close/abort) and cache flushing.
mfc_core_hwlock.h
APIs for initializing, acquiring and releasing hardware locks
for both device and context structures.
mfc_core_isr.h
ISR prototypes for top‑half and threaded interrupt handling.
mfc_core_run.h
Functions for cache flush, hardware initialization,
de‑initialization, and power state transitions (sleep/wakeup).
All files reference the common core structures via base/mfc_common.h.
This patch prepares the interface layer for upcoming implementation
changes in the MFC driver.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
Introduce a new Kconfig entry VIDEO_EXYNOS_MFC for the Samsung
Exynos MFC driver that supports firmware version 13 and later.
Extend the top‑level Samsung platform Kconfig to disable the legacy
S5P‑MFC driver when its firmware version is > v12 and to select the
new Exynos‑MFC driver only when VIDEO_SAMSUNG_S5P_MFC is not enabled.
Add exynos-mfc Kconfig and Makefile for probe functionality and creation
of decoder and encoder device files by registering the driver object
exynos_mfc.o and other relevant source files.
Provide header files mfc_core_ops.h and mfc_rm.h containing core
operation prototypes, resource‑manager helpers,
and core‑selection utilities.
Add a configurable option MFC_USE_COREDUMP to enable core‑dump
support for debugging MFC errors.
These changes bring support for newer Exynos‑based MFC hardware,
cleanly separate it from the legacy S5P‑MFC driver, and lay the
groundwork for future feature development and debugging.

+ reboot. Use this option only when debugging is needed, as it

No, NAK. Existing driver is well tested and already used on newest
Exynos SoC, so all this new driver is exactly how you should not work
in upstream. You need to integrate into existing driver.
Samsung received this review multiple times already.

Please don't be so categorical. The MFC hardware evolved quite a bit
from the ancient times of S5PV210 SoC, when s5p-mfc driver was designed.
The feature list of the new hardware hardly matches those and I really
don't see the reason for forcing support for so different hardware in a
single driver. Sometimes it is easier just to have 2 separate drivers if
the common part is just the acronym in the hardware block name...
Best regards

I know it is easier for Samsung to write new driver, but this should
answer to - why the maintainers and the community would like to
maintain two drivers. Sure, make a case why we would like to take this
code.
The easiest argument here why we wouldn't is: new vendor downstream
code means replicating all known issues, old coding style, everything
which we already fixed and changed.

And 15 second look at one of the patches already confirmed this:
replicating downstream issue - undocumented DT ABI not following
current style, code relying on some other downstream drivers. 15
seconds was enough to find it.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Optional bus‑devfreq support (CONFIG_MFC_USE_BUS_DEVFREQ).
- New control framework (mfc_ctrl_type, mfc_ctrl_mode, ops structs).
- QoS and per‑context/core power‑clock handling.
- Multi‑view / depth‑map support with related buffers and constants.
- Added helper macros (mfc_macros.h) and extra pixel formats.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Implement full buffer queue and DPB management (mfc_queue).
- Extended mfc_common.h with runtime/boost macros and helper calls.
- Added IOVMM helpers ; DPB allocation now uses IOVMM.
- Introduced macros for MMCache timeout, boost timing,
resolution thresholds, default runtime, and codec limits.
- Refined debug and error handling throughout.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Implement runtime rate‑calculation (timestamp handling, framerate/BPS
estimation, QoS adjustments, performance checks) with new helper APIs.
- Add utility layer for format validation, resolution/stride/size
computation, DPB size, address mapping, and view‑buffer bookkeeping.
- Export functions used by decoder/encoder paths for dynamic QoS and
memory handling.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Implement QoS support (load estimation, dynamic level adjustment,
PM‑QoS & idle‑mode handling)
- Add mfc_qos.c/h and integrate it into the Makefile
- Introduce instance‑context allocation/release APIs
(mfc_alloc_instance_context, mfc_release_instance_context)
- Update driver code to use the new APIs and add debugging/trace hooks
- Provide documentation/comments for the new functionality

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Add core command extensions and decoder‑specific commands.
- Update core register APIs with helpers for processing‑cycle,
DPB, scratch size, SEI, black‑bar detection, MVC IDs, profile,
display delay, two‑core mode, and inline utilities for crop info,
tag updates, migration address, and multi‑core context flush.
- Refactor core synchronization: migration‑aware lock functions,
wait‑queues to prevent races, targeted wake‑ups, and ready‑bit
handling for header parsing, frame decoding, buffer setup,
resolution changes, and two‑core DRC paths.
- Add macros, helper functions, comments, and debug prints
to support the new decoder‑side core coordination and
upcoming multi‑core decoding.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Add core buffer‑control module (mfc_core_buf_ctrl.c)
with set/get/recover/restore ops.
- Add context‑control layer (mfc_ctx_ctrl.c) defining
V4L2 decoder controls and per‑buffer handling.
- Export mfc_bufs_ops and mfc_ctrls_ops for integration
with existing MFC core
Provide flexible V4L2‑based management of hardware registers,
including volatile/non‑volatile settings and buffer‑level
restore/recovery.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Introduce dynamic load‑balancing and core‑selection for MFC decoder.
- Add complete RM infrastructure: real‑time QoS, multi‑core handling,
core migration.
- Implement per‑core load tracking and weighted‑MB calculation.
- Refactor driver paths (open/close/setup/stop, buffer movement, Butler
requests) to use the RM layer and improve error handling/cleanup.
- Enables dual‑core utilization, real‑time priority support,
and prepares the driver for upstream/mainline integration.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Enable HW‑lock migration across cores and centralize lock
acquisition for better load‑balancing and dynamic resolution.
- Refactor decoder run‑path helpers to streamline init,
per‑frame, and final‑frame processing with dynamic DPB management.
- Add IRQ‑level lock handler that deals with pre‑empted contexts,
waiting queues, QoS updates and work scheduling,
reducing race conditions.
- Expand QoS tracking and black‑bar detection with detailed debug output.
- Consolidate error handling into a dedicated ISR‑invoked path,
improving recovery reliability and logging.
- Update headers/comments and add missing declarations for new helpers.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Implement VB2 queue operations for decoding (setup, buffer handling,
streaming control, multi‑view and DMA direction support).
- Added header exposing decoder VB2 operations to other MFC components.
This introduces a full VB2 backend for video decoding, aligning the driver
with standard V4L2 buffer management.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
Add a V4L2‑based decoder for Exynos MFC.
- Implement full decoder V4L2 ioctl, control, buffer, and stream handling.
- Provide ioctl getter and default format helper.
Move the decoder to the standard V4L2 framework,
to enable proper media‑device registration and user‑space interaction.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Integrate QoS handling (core, ops, PM).
- Add Butler workqueue for core tasks (allocation, init, cleanup).
- Implement async QoS control workqueue using atomic counters
and proper sync.
- Update probe to initialize workqueues, QoS structures,
and improve logging.
- Modify PM to trigger QoS updates on clock changes and issue
idle‑clock QoS when bus devfreq is active.
- Refactor scheduler for priority‑aware work handling
via bit‑mask tracking.
- Extend ops table with extra instance and buffer management.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Extend device‑tree with properties for secure firmware, DRM, codec
capabilities, format/stride, resolution checks, and security controls.
- Introduce per‑codec and device‑wide bitrate limits.
- Implement runtime management: scheduler workers, dedicated workqueues,
and required mutex/spinlock synchronization.
- Refine decoder‑context handling (full init/cleanup, CRC dump,
DPB handling, vb2 queue setup, QoS parsing).
- Add polling with error‑state handling.
- Expand DebugFS to expose core‑balance, feature flags, format support,
QoS data, and queue metrics.
- Update macros, include missing headers, improve logging, adjust
scheduler/PBS configuration, and revise buffer‑size structures.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Enable HEVC, AV1, VP8/9, MPEG‑4 (incl. MVC, VC‑1 RCV) .
- Extend DPB/buffer structures for AV1 and high‑resolution/multiframe
streams.
- Add codec‑specific QoS weight parameters (10‑bit, 4:2:2, B‑frames)
and update DT bandwidth entries.
- Enhance format tables with colour‑range/space and HDR parsing for VP9.
- Detect display‑resolution changes and multiframe flags for VP9/AV1.
- Introduce utility helpers (CRC, aspect‑ratio, colour primaries)
and minor safety fixes.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Integrat H.264 encoding.
- Allocate encoder‑specific context buffers and ROI memory.
- Add detection macro and broadened codec‑type validation for
QoS utilities.
- Introduce encoder‑aware QoS tables and refined weight calculations
(B‑frames, reference count).
- Update source‑queue cleanup, framerate fallback, and
timestamp‑delta handling.
- Make stride and source‑size helpers encoder‑aware; exposed B‑frame
detection utility.
- Expand context structures with encoder buffers, private fields,
ROI, and parameters.
- Add platform flags for encoder‑specific QoS steps and feature
support (e.g., RGB).

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Introduce a generic encoder‑parameter framework
(slice mode, ASO order, QP config, timestamp delta).
- Expose full V4L2 encoder controls (frame tag, RC limits,
level/profile, ROI, weighted prediction, hierarchical coding).
- Implemente ROI handling by building ROI registers from
per‑buffer data.
- Update encoder resource manager: fixed core integration,
excluded from migration/load‑balancing, ensured proper
finalization per buffer type, and add encoder‑specific
QoS step table.
- Disable bitrate‑driven load‑balancing for encoders;
framerate updates now apply only to non‑encoder contexts.

- Register H.264 format and V4L2/VB2 headers.
- Initialize encoder context, queues, and defaults.
- Add buffer‑control handling (layers, ROI, frame‑rate, drop,
profile/level) and parse DT properties.
- Register encoder ioctl ops, set up QoS table, and extend debugfs.

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Introduce generic codec‑mode macros for MPEG‑4, VP8, VP9, HEVC
- Extend 4:2:2 format handling and IDR‑frame processing
- Suppress IVF headers for VP8/VP9 when disabled
- Enable multi‑core processing for HEVC and refine instance opening flow
- Expand mfc_enc_params with codec‑specific fields
and raise resolution limits
- Add new V4L2 controls (profiles, levels, QP, hierarchical coding,
golden frames, etc.)
- Implement VP9 HDR, colour‑space mapping, HEVC ROI,
and extra debug logging

From: Nagaraju Siddineni <nagaraju.s@samsung.com>
- Add for MPEG‑4, H.263, VP8/VP9, HEVC codec support with extended
contexts and buffer allocation.
- Implement LCU sizing, motion‑estimation buffers, and align
scratch buffers.
- Unify ROI buffer handling across all encoders.
- Register additional pixel formats (`mfc_format.h`).
- Enhance QoS weighting and B‑frame/reference‑count logic.
- Introduce hierarchical‑coding
controls (layer count, per‑layer bitrate)
and SVC for HEVC, VP8, VP9.
- Update timestamp handling for H.263 and improved VP8 buffer‑exhaustion
error reporting.

I wont deny that sometimes a new driver is needed, and I encourage you to defend
your point. It does just justify any form of copy paste, also understand that
device descriptions should be independent from the driver implementation. This
is also why this is reviewed indecently, and DT nack won't ever be ignored by
us.
From quick walk through, I'm not convince this new driver actually makes use of
everything new in Linux and Linux Media since 2011. It will be important for you
to research what other modern drivers do, and what could apply to your code
base. I'm quite skeptical with all the custom memory handling code, which
generally indicates the miss-use of dma APIs. Realistically, you will have to
split your driver in smaller parts and submit in a way we can see your design
principle, and not just randomly unused files being added. Considering the state
of it, we are up to 20 or 30 revision, with 29 patches, you won't get to the end
of that process.
V4L2 wise, one of the common mistakes is that you are adding a lot of new
controls, most of them just slammed as vendor control without even trying to
generalize. It did make sense in 2011, since there was no decoder to compare
against, but today there is a lot of example and overlap between various brand.
Omitting documentation and not keeping the API addition separate is also a no go
for me. Make it very clear whenever something that will live in our API forever
is to be added.
We also added rules since 2011 that enforce drivers submitter to show that
proper testing have occurred. Its starts with the very basic v4l2-compliance
report which you have omitted. Since its codec driver, we require a summary of
your conformance decoding testing done with fluster[] with the supported
framework of your choice (for v4l2 stateful, ffmpeg and gstreamer are supported,
you can add more, as long as they are open source).
We also expect that your firmware has been submitted to linux-firmware with a
link to that submission. Without that, we can only consider your set as an RFC
to show people what is coming.

Nicolas

I did some (admittedly limited) comparison between the MFC hardware registers in patch 04/29
and what is in s5p-mfc and it did look like an incremental update, not a complete register redesign.
So I am not convinced from that that a new driver is needed.
In addition, a huge patch bomb like this is unreviewable and so I am just going to give a
few high-level remarks based on a quick scan of the patches.
1) Clearly you never ran v4l2-compliance with this new driver as it would fail immediately
on the VIDIOC_QUERYCAP ioctl. It's a M2M device, so it should use either V4L2_CAP_VIDEO_M2M
or V4L2_CAP_VIDEO_M2M_MPLANE, not a mix of output and capture caps. I suspect that
v4l2-compliance will fail on many issues.
2) I noticed that there is no VB2_MMAP support. No idea why not, and all drivers with streaming I/O
support must support VB2_MMAP.
3) Lots of controls are added, none of them documented or even defined in a public header.
It's part of the public API, so that must all be present in include/uapi/linux. Just
'git grep' for CID_MPEG_MFC51 to see how it should be done. I suspect that more than a few
of these controls are either duplicated of already existing controls or should be promoted
from MFC-specific controls to generic controls. But without documentation we can't tell.
4) Since this is a new M2M driver I would expect it to use the v4l2-mem2mem framework, instead
it appears to be all homegrown. The only reason the existing s5p-mfc driver doesn't use that
framework is because it predates it.
5) It clearly doesn't follow the stateful encoder/decoder interface spec as detailed in the
V4L2 spec:
https://linuxtv.org/downloads/v4l-dvb-apis-new/userspace-api/v4l/dev-mem2mem.html
Even s5p-mfc does at least attempt to follow that (I'm not sure how complete support is,
given that it's an old driver, but it tries).
6) Minor issue: don't set the .wait_prepare/finish vb2_ops callbacks: these callbacks are
slated for removal. Instead set the vb2_queue lock field to the mutex &dev->mfc_mutex.
There are probably many other things that need addressing, but I stopped there.
I would need convincing (and based on his reply, Krzysztof as well) that a new driver is the
right approach. If it is, then start small: just the decoder supporting just one codec.
Exclude all the fancy features, just start with the basics. The recently merged Qualcomm
iris driver can serve as inspiration: drivers/media/platform/qcom/iris/
I'll mark this series as Rejected in patchwork. It's always a very bad idea to try to upstream
a huge driver with zillions of features. If, like this one, it has serious design issues, then
you did a lot of work for nothing :-(
Apologies for the bad news,
Regards,
Hans
