Hence, add support to read reserved fixed memory region from device-tree and provide the reserved memory segments for firmware to use during QMI firmware memory request. Note that the ability to set the fixed memory will be introduced in a subsequent patch. Currently, the flag remains unset by default, ensuring that existing chipsets are unaffected.

WCSS driver handles loading and booting of rootPD, while the ath12k driver boots the userPD. Get the rproc handle from the DTS entry and boot the rootPD if it is not already powered on. Register to the rproc notifier to monitor the rproc state, this allows ath12k driver to know power up/down sequence of the rootPD. Power up the rootPD and wait for a power-up notification from the notifier callback before powering up the userPDs.

Spawn interrupt is triggered once the userPD thread is spawned. Ready interrupts denotes userPD is completely powered up and ready. Stop-ack is to acknowledge the ath12k driver that userPD is stopped. Ath12k driver needs to set spawn bit in SMEM to instruct Q6 to spawn a userPD. Similarly stop bit is set when userPD needs to be stopped.

Refactor Ath12k module_init and module_exit to include Ath12k AHB support. Add Ath12k AHB support in Kconfig with dependency on Remoteproc driver. Ath12k AHB support relies on remoteproc driver for firmware download, power up/down etc. Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.3.1-00130-QCAHKSWPL_SILICONZ-1 Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00210-QCAHKSWPL_SILICONZ-1 Signed-off-by: Balamurugan S Co-developed-by: P Praneesh Signed-off-by: P Praneesh Signed-off-by: Raj Kumar Bhagat --- drivers/net/wireless/ath/ath12k/Kconfig | 6 ++++ drivers/net/wireless/ath/ath12k/Makefile | 1 + drivers/net/wireless/ath/ath12k/ahb.h | 11 ++++++++ drivers/net/wireless/ath/ath12k/core.c | 35 ++++++++++++++++++++++-- drivers/net/wireless/ath/ath12k/pci.c | 10 ++----- drivers/net/wireless/ath/ath12k/pci.h | 4 ++- 6 files changed, 55 insertions(+), 12 deletions(-) diff --git a/drivers/net/wireless/ath/ath12k/Kconfig b/drivers/net/wireless/ath/ath12k/Kconfig index 52a1bb19e3da..7782dd131c62 100644 --- a/drivers/net/wireless/ath/ath12k/Kconfig +++ b/drivers/net/wireless/ath/ath12k/Kconfig @@ -15,6 +15,12 @@ config ATH12K If you choose to build a module, it'll be called ath12k. +config ATH12K_AHB + bool "QTI ath12k AHB support" + depends on ATH12K && REMOTEPROC + help + Enable support for Ath12k AHB bus chipsets, example IPQ5332. + config ATH12K_DEBUG bool "ath12k debugging" depends on ATH12K diff --git a/drivers/net/wireless/ath/ath12k/Makefile b/drivers/net/wireless/ath/ath12k/Makefile index 60644cb42c76..d95ee525a6cd 100644 --- a/drivers/net/wireless/ath/ath12k/Makefile +++ b/drivers/net/wireless/ath/ath12k/Makefile @@ -23,6 +23,7 @@ ath12k-y += core.o \ fw.o \ p2p.o +ath12k-$(CONFIG_ATH12K_AHB) += ahb.o ath12k-$(CONFIG_ATH12K_DEBUGFS) += debugfs.o debugfs_htt_stats.o debugfs_sta.o ath12k-$(CONFIG_ACPI) += acpi.o ath12k-$(CONFIG_ATH12K_TRACING) += trace.o diff --git a/drivers/net/wireless/ath/ath12k/ahb.h b/drivers/net/wireless/ath/ath12k/ahb.h index f8a5c43075c1..d56244b20a6a 100644 --- a/drivers/net/wireless/ath/ath12k/ahb.h +++ b/drivers/net/wireless/ath/ath12k/ahb.h @@ -66,4 +66,15 @@ static inline struct ath12k_ahb *ath12k_ab_to_ahb(struct ath12k_base *ab) return (struct ath12k_ahb *)ab->drv_priv; } +#ifdef CONFIG_ATH12K_AHB +int ath12k_ahb_init(void); +void ath12k_ahb_exit(void); +#else +static inline int ath12k_ahb_init(void) +{ + return 0; +} + +static inline void ath12k_ahb_exit(void) {}; +#endif #endif diff --git a/drivers/net/wireless/ath/ath12k/core.c b/drivers/net/wireless/ath/ath12k/core.c index 5bd852f9572b..4117ccd1af20 100644 --- a/drivers/net/wireless/ath/ath12k/core.c +++ b/drivers/net/wireless/ath/ath12k/core.c @@ -10,15 +10,18 @@ #include #include #include +#include "ahb.h" #include "core.h" #include "dp_tx.h" #include "dp_rx.h" #include "debug.h" -#include "hif.h" -#include "fw.h" #include "debugfs.h" +#include "fw.h" +#include "hif.h" +#include "pci.h" #include "wow.h" +static int ahb_err, pci_err; unsigned int ath12k_debug_mask; module_param_named(debug_mask, ath12k_debug_mask, uint, 0644); MODULE_PARM_DESC(debug_mask, "Debugging mask"); @@ -2020,5 +2023,31 @@ struct ath12k_base *ath12k_core_alloc(struct device *dev, size_t priv_size, return NULL; } -MODULE_DESCRIPTION("Core module for Qualcomm Atheros 802.11be wireless LAN cards."); +static int ath12k_init(void) +{ + ahb_err = ath12k_ahb_init(); + if (ahb_err) + pr_warn("Failed to initialize ath12k AHB device: %d\n", ahb_err); + + pci_err = ath12k_pci_init(); + if (pci_err) + pr_warn("Failed to initialize ath12k PCI device: %d\n", pci_err); + + /* If both failed, return one of the failures (arbitrary) */ + return ahb_err && pci_err ? ahb_err : 0; +} + +static void ath12k_exit(void) +{ + if (!pci_err) + ath12k_pci_exit(); + + if (!ahb_err) + ath12k_ahb_exit(); +} + +module_init(ath12k_init); +module_exit(ath12k_exit); + +MODULE_DESCRIPTION("Driver support for Qualcomm Technologies 802.11be WLAN devices"); MODULE_LICENSE("Dual BSD/GPL"); diff --git a/drivers/net/wireless/ath/ath12k/pci.c b/drivers/net/wireless/ath/ath12k/pci.c index b474696ac6d8..e62b172c7f9f 100644 --- a/drivers/net/wireless/ath/ath12k/pci.c +++ b/drivers/net/wireless/ath/ath12k/pci.c @@ -1831,7 +1831,7 @@ static struct pci_driver ath12k_pci_driver = { .driver.pm = &ath12k_pci_pm_ops, }; -static int ath12k_pci_init(void) +int ath12k_pci_init(void) { int ret; @@ -1844,14 +1844,8 @@ static int ath12k_pci_init(void) return 0; } -module_init(ath12k_pci_init); -static void ath12k_pci_exit(void) +void ath12k_pci_exit(void) { pci_unregister_driver(&ath12k_pci_driver); } - -module_exit(ath12k_pci_exit); - -MODULE_DESCRIPTION("Driver support for Qualcomm Technologies PCIe 802.11be WLAN devices"); -MODULE_LICENSE("Dual BSD/GPL"); diff --git a/drivers/net/wireless/ath/ath12k/pci.h b/drivers/net/wireless/ath/ath12k/pci.h index 31584a7ad80e..521fa72333bb 100644 --- a/drivers/net/wireless/ath/ath12k/pci.h +++ b/drivers/net/wireless/ath/ath12k/pci.h @@ -1,7 +1,7 @@ /* SPDX-License-Identifier: BSD-3-Clause-Clear */ /* * Copyright (c) 2019-2021 The Linux Foundation.
