As a result, QMI message sequence is not same as other ath11k supported devices. Also, M3 firmware will be bundled into the FW and will be downloaded to the target as part of Q6 boot. This is the QMI flow in the case of WCN6750, 1) QMI firmware indication REQ/RESP 2) QMI host capability REQ/RESP 3) QMI target capability REQ/RESP 4) QMI device info REQ/RESP 5) QMI BDF download 6) QMI FW ready Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00573-QCAMSLSWPLZ-1 Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1 Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.5.0.1-01100-QCAHKSWPL_SILICONZ-1 Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-00192-QCAHKSWPL_SILICONZ-1 Signed-off-by: Manikanta Pubbisetty --- drivers/net/wireless/ath/ath11k/qmi.c | 73 +++++++++++++++++++++++------------ 1 file changed, 48 insertions(+), 25 deletions(-) diff --git a/drivers/net/wireless/ath/ath11k/qmi.c b/drivers/net/wireless/ath/ath11k/qmi.c index ee59cb9..4745ff9 100644 --- a/drivers/net/wireless/ath/ath11k/qmi.c +++ b/drivers/net/wireless/ath/ath11k/qmi.c @@ -1793,10 +1793,6 @@ static int ath11k_qmi_fw_ind_register_send(struct ath11k_base *ab) req->client_id = QMI_WLANFW_CLIENT_ID; req->fw_ready_enable_valid = 1; req->fw_ready_enable = 1; - req->request_mem_enable_valid = 1; - req->request_mem_enable = 1; - req->fw_mem_ready_enable_valid = 1; - req->fw_mem_ready_enable = 1; req->cal_done_enable_valid = 1; req->cal_done_enable = 1; req->fw_init_done_enable_valid = 1; @@ -1805,6 +1801,17 @@ static int ath11k_qmi_fw_ind_register_send(struct ath11k_base *ab) req->pin_connect_result_enable_valid = 0; req->pin_connect_result_enable = 0; + /* WCN6750 doesn't request for DDR memory via QMI, + * instead it uses a fixed 12MB reserved memory + * region in DDR. + */ + if (!ab->bus_params.hybrid_bus_type) { + req->request_mem_enable_valid = 1; + req->request_mem_enable = 1; + req->fw_mem_ready_enable_valid = 1; + req->fw_mem_ready_enable = 1; + } + ret = qmi_txn_init(handle, &txn, qmi_wlanfw_ind_register_resp_msg_v01_ei, resp); if (ret < 0) @@ -2490,6 +2497,13 @@ static int ath11k_qmi_wlanfw_m3_info_send(struct ath11k_base *ab) struct qmi_txn txn; int ret = 0; + /* In the case of WCN6750, M3 is bundled into the FW + * binary, and will be downloaded as part of Q6 boot. + */ + if (!ab->bus_params.m3_fw_support && + ab->bus_params.hybrid_bus_type) + return 0; + memset(&req, 0, sizeof(req)); memset(&resp, 0, sizeof(resp)); @@ -2821,27 +2835,6 @@ ath11k_qmi_driver_event_post(struct ath11k_qmi *qmi, return 0; } -static int ath11k_qmi_event_server_arrive(struct ath11k_qmi *qmi) -{ - struct ath11k_base *ab = qmi->ab; - int ret; - - ret = ath11k_qmi_fw_ind_register_send(ab); - if (ret < 0) { - ath11k_warn(ab, "failed to send qmi firmware indication: %d\n", - ret); - return ret; - } - - ret = ath11k_qmi_host_cap_send(ab); - if (ret < 0) { - ath11k_warn(ab, "failed to send qmi host cap: %d\n", ret); - return ret; - } - - return ret; -} - static int ath11k_qmi_event_mem_request(struct ath11k_qmi *qmi) { struct ath11k_base *ab = qmi->ab; @@ -2892,6 +2885,36 @@ static int ath11k_qmi_event_load_bdf(struct ath11k_qmi *qmi) return ret; } +static int ath11k_qmi_event_server_arrive(struct ath11k_qmi *qmi) +{ + struct ath11k_base *ab = qmi->ab; + int ret; + + ret = ath11k_qmi_fw_ind_register_send(ab); + if (ret < 0) { + ath11k_warn(ab, "failed to send qmi firmware indication: %d\n", + ret); + return ret; + } + + ret = ath11k_qmi_host_cap_send(ab); + if (ret < 0) { + ath11k_warn(ab, "failed to send qmi host cap: %d\n", ret); + return ret; + } + + if (!ab->bus_params.hybrid_bus_type) + return ret; + + ret = ath11k_qmi_event_load_bdf(qmi); + if (ret < 0) { + ath11k_warn(ab, "qmi failed to download BDF:%d\n", ret); + return ret; + } + + return ret; +} + static void ath11k_qmi_msg_mem_request_cb(struct qmi_handle *qmi_hdl, struct sockaddr_qrtr *sq, struct qmi_txn *txn,
