Current ath drivers have separate implementations for different
classes of devices. For example, ath11k supports WiFi-6 devices,
while ath12k supports Wi-Fi 7 devices. However, there is significant
common functionality across these generations due to shared firmware
and hardware architecture. In the existing driver code, this leverage
is achieved through code duplication. As a result, when a new driver
is introduced, many features are missed, and new additions require
porting across different generation drivers.
To improve reuse and maintainability, ath12k should be split into common
and device-specific modules. Common code can be shared across multiple
architectures, enabling better leverage for future hardware generations.
generation drivers.
Firmware interfaces and core initialization sequences are typically common
across different device families. In contrast, hardware register offsets, copy
engine mappings, and HAL configurations are usually hardware-specific.
Common components include:
- mac80211 interface: Control path operations are mostly common across
different ATH hardware and will be shared as much as possible.
- Firmware interface (WMI, HTT, HTC, QMI): Firmware messaging and
sequences are common and maintained with backward/forward compatibility
using TLVs.
- Datapath: Data path files are also separated similarly. More information
will be provided in later patches.
- Core initialization, reset, and recovery sequences: These will be part
of the shared code.
Device-specific code includes:
- Hardware capabilities, configurations, HAL, and other
architecture-specific logic.
The original ath12k.ko is split into these two modules as depicted below.
+-----------------+
| |
| ath12k.ko |
| (common) |
+---------------+ | |
| | +-----------------+
| ath12k.ko | ===========>
| | +------------------+
+---------------+ | |
| ath12k_wifi7.ko |
| (wifi7 family) |
| |
+------------------+
The ath12k.ko module will serve as the common component, while ath12k_wifi7.ko
will be the architecture-specific module for WiFi-7 devices.
After this modular separation, adding support for a new device will
primarily involve implementing device-specific code, while reusing the
majority of the shared common components.

Refactor pci.c to split common and hardware family specific components.
Retain shared logic such as probe and initialization sequences in common
pci.c to support reuse across device families and move Wi-Fi 7 specific
initialization and configuration to a new pci_wifi7.c file. Register
device specific routines via callbacks to keep the common PCI code
generic and extensible for future hardware families.
This improves maintainability and prepare the codebase for additional
device family support.

From: Kiran Venkatappa @ 2025-08-12 17:09 UTC (permalink / raw)
To: ath12k; +Cc: linux-wireless
Relocate Copy Engine (CE) assignment logic from ce.c to a new ce_wifi7.c
file to consolidate Wi-Fi 7 specific CE configuration in one place.
Move CE service map and target configuration from hw.c to ce_wifi7.c.
This reorganization improves code clarity and modularity by isolating
device-specific logic. It is part of a broader effort to separate
common and hardware-specific code into distinct modules.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

To: ath12k; +Cc: linux-wireless
Relocate Wi-Fi 7 specific WMI configuration from shared codebase to a new
target-specific file. Isolate WMI settings per target to improve
modularity and maintainability.
This change is part of a broader effort to separate hardware-dependent
logic into standalone modules, paving the way for cleaner support of
multiple hardware families

From: Kiran Venkatappa @ 2025-08-12 17:09 UTC (permalink / raw)
To: ath12k; +Cc: linux-wireless
Relocate target-specific MHI configuration to a new mhi_wifi7.c file to
isolate Wi-Fi 7 related logic from the common codebase.
Improve modularity by separating hardware-dependent code from shared
components.
Enhance maintainability and prepare the driver for clean integration of
additional device families.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

Rename hw.c to hw_wifi7.c to reflect its focus on Wi-Fi 7 chipset
specific configurations. Clarify the files role in containing
hardware dependent logic tailored to the Wi-Fi 7 family.
This change is part of a broader effort to modularize the codebase
by separating common and target specific components into distinct
modules for improved clarity and maintainability.

Rename ahb_hif_ops structure to remove the IPQ5322 qualifier and reflect
its generic applicability across multiple targets. Clarify its role as a
container for common HIF callbacks.
This renaming is part of a broader effort to modularize the codebase
by separating common logic from device-specific implementations.

Split ahb.c into a common module (ahb.c) and a Wi-Fi 7 specific module
(ahb_wifi7.c). Retain shared logic-such as probe and initialization
sequences-in ahb.c to support reuse across hardware families.
Move Wi-Fi 7 specific initialization and configuration routines to
ahb_wifi7.c and register them via callbacks.
This modular approach improves code organization and prepares the
driver for scalable support of additional hardware families.

To: ath12k; +Cc: linux-wireless
Move Wi-Fi 7 specific module initialization and exit routines from core.c
to a new core_wifi7.c file. Decouple these routines from common module
entry points to improve modularity.
This restructuring is part of a broader effort to modularize the
ATH12K driver by separating common logic from hardware family-specific
implementations, improving maintainability and scalability.

To: ath12k; +Cc: linux-wireless
Relocate hw_init call from the shared probe path to target-specific
probe implementations. Handle Wi-Fi 7 initialization entirely within
its corresponding target-specific file.
Improve modularity by decoupling hardware-dependent initialization from
common probe logic. Support broader effort to separate shared and
target-specific code paths.

From: Kiran Venkatappa @ 2025-08-12 17:09 UTC (permalink / raw)
To: ath12k; +Cc: linux-wireless
Split the ath12k driver into two kernel modules:
- ath12k.ko for shared logic across multiple targets
- ath12k_wifi7.ko for Wi-Fi 7 specific configuration and routines
The common module (ath12k.ko) must be loaded prior to any device-specific
module, as the latter depends on exported symbols from the former.
As part of this restructuring, Wi-Fi 7 specific files are moved into a
dedicated `wifi7/` directory and built as a separate module. Common
symbols are exported accordingly, with further adjustments planned
in upcoming patches to support architecture-dependent separation.
This modularization improves maintainability and scalability by enabling
clean separation of hardware-specific logic from the shared driver core.

From: Kiran Venkatappa @ 2025-08-12 17:09 UTC (permalink / raw)
To: ath12k; +Cc: linux-wireless
Rename functions and global definitions from ath12k_* to ath12k_wifi7_*
to reflect their association with the Wi-Fi 7 specific module.
Align symbol naming with recent relocation of components into the
ath12k/wifi7 directory.
This change improves code clarity and supports the modularization effort
that separates common and hardware-specific logic into distinct modules.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

Eliminate use of HAL-specific defines in the shared PCI implementation.
Pass required register offsets during PCI registration and store them in
the PCI context structure. Access offsets directly from the context to
improve modularity and remove hardware-specific dependencies in the
common code path.

Eliminate HAL-specific defines from the shared AHB implementation.
Store the WFSS register base-already available in hw_params via the
ce_remap structure-in the AHB context and access it directly.
Add the CMEM offset to the ce_remap structure and use it consistently in
shared code. Improve modularity by removing hardware abstraction layer
dependencies from common code paths and enable cleaner separation of
target-specific logic

Don't rewrite the copyrights. Original file had different one. GPL FAQ
also EXPLICITLY asks for date in copyrights and does not allow one
without the date.

Wi-Fi team wasn't party to the other thread, and this series was following the
legal guidance we were given. I'm circling with the core kernel team and the
legal team to make sure your concerns are resolved.

Nope, we do NOT force the FSF's legal intrepretation of copyright marks
on any company at all. It's up to the copyright holders themselves for
how they wish to mark the copyright, if at all.
And really, Qualcomm is a company that is run by lawyers, they know what
they want to do for whatever reason that might be...

Agreed, but in some cases, I have forced legal teams to sign off on
patches, so don't rule that out :)

Thanks for the clarification, Greg.
Just for reference, the guidance we received follows. In that guidance:
- LF means Linux Foundation, the entity to which Qualcomm assigned copyright
when open source development was being done as Code Aurora Forum (though
December 2021)
- QuIC means Qualcomm Innovation Center, the open source entity used from
December 2021 until March 2025.
- QTI means Qualcomm Technologies, Inc., the entity now being used for open
source contributions.
Guidance:
1. Should existing QuIC copyright be left alone or absorbed into the added QTI
copyright text?
Yes, all QuIC copyright years should be absorbed. Replace the QuIC copyrights
with the QTI copyright. Leave LF and other 3rd party copyrights alone.
2. When we are creating new file in open source, if it is copied/derived from
existing QUIC authored open source file, should we retain the QUIC markings?
No, the QuIC copyright years should be absorbed into the year-less QTI copyright.
3. Is there any use case where we MUST keep the QuIC copyright?
No, all projects can move to using QTI copyright.
