Device group abstraction - when there are multiple devices that are connected by any means of communication interface between them, then these devices can be combined together as a single group using a group id to form a group abstraction. In ath12k driver, this abstraction would be named as ath12k_hw_group (ag). Please find below illustration of device group abstraction with two devices. Grouping of multiple devices (in future) +------------------------------------------------------------------------+ | +-------------------------------------+ +-------------------+ | | | +-----------+ | | +-----------+ | | +-----------+ | | | | | ar (2GHz) | | | | ar (5GHz) | | | | ar (6GHz) | | | | | +-----------+ | | +-----------+ | | +-----------+ | | | | ath12k_base (ab) | | ath12k_base (ab) | | | | (Dual band device) | | | | | +-------------------------------------+ +-------------------+ | | ath12k_hw_group (ag) based on group id | +------------------------------------------------------------------------+ Say for example, device 1 has two radios (2 GHz and 5 GHz band) and device 2 has one radio (6 GHz). In existing code - device 1 will have two hardware abstractions hw1 (2 GHz) and hw2 (5 GHz) will be registered separately to mac80211 as phy0 and phy1 respectively. Similarly, device 2 will register its hw (6GHz) as phy2 to mac80211. In future, with multi-link abstraction combination 1 - Different group id for device1 and device 2 Device 1 will create a single hardware abstraction hw1 (2 GHz and 5 GHz) and will be registered to mac80211 as phy0. similarly, device 2 will register its hardware (6 GHz) to mac80211 as phy1. combination 2 - Same group id for device1 and device 2 Both device details are combined together as a group, say group1, with single hardware abstraction of radios 2 GHz, 5 GHz and 6 GHz band details and will be registered to mac80211 as phy0. Add base infrastructure changes to add device grouping abstraction with a single device. This patch series brings the base code changes with following order: 1. Refactor existing code which would facilitate in introducing device group abstraction. 2. Create a device group abstraction during device probe. 3. Start the device group only after QMI firmware ready event is received for all the devices that are combined in the group. 4. Move the hardware abstractions (ath12k_hw - ah) from device (ath12k_base - ab) to device group abstraction (ag) as it would ease in having different combinations of group abstraction that can be registered to mac80211. v3: - Removed depends-on tag of "wifi: ath12k: Refactor the hardware recovery procedures" as it is merged to ToT - Addressed the deadlock warning seen during rmmod. v2: - Rebased to ToT Karthikeyan Periyasamy (8): wifi: ath12k: Refactor core start api wifi: ath12k: Add helpers to get or set ath12k_hw wifi: ath12k: Add ath12k_get_num_hw api wifi: ath12k: Introduce QMI firmware ready flag wifi: ath12k: move ATH12K_FLAG_REGISTERED flag set to mac_register api wifi: ath12k: Introduce device group abstraction wifi: ath12k: refactor core start based on hardware group wifi: ath12k: move ath12k_hw from per soc to group drivers/net/wireless/ath/ath12k/core.c | 433 +++++++++++++++++++++---- drivers/net/wireless/ath/ath12k/core.h | 87 ++++- drivers/net/wireless/ath/ath12k/mac.c | 108 ++++-- drivers/net/wireless/ath/ath12k/mac.h | 9 +- drivers/net/wireless/ath/ath12k/pci.c | 2 + drivers/net/wireless/ath/ath12k/qmi.c | 10 +- 6 files changed, 534 insertions(+), 115 deletions(-) base-commit: 2c4d8e19cf060744a9db466ffbaea13ab37f25ca
