This Qualcomm QDU100 device is inline accelerator card which is an extension to QRU100 5G RAN platform. which is designed to simplify 5G deployments by offering a turnkey solution for ease of deployment with O-RAN fronthaul and 5G NR layer 1 High (L1 High) processing, and to accelerate operator and infrastructure vendor adoption of virtualized RAN platforms. Currently IP_SW1/2 channel support is not present in mhi_net driver, will be supporting them in future. https://docs.qualcomm.com/bundle/publicresource/87-79371-1_REV_A_Qualcomm_X= 100_5G_RAN_Accelerator_Card_Product_Brief.pdf Signed-off-by: Vivek Pernamitta --- changes from V1: - Changing naming convention from modem_qcom_qdu100* to mhi_qcom_qdu100* - Added more commit test for IP_SW1/2 channels. - Fixed and corrected by passing mhi_pci_dev_info struct instead of mhi_controller_config. --- --- drivers/bus/mhi/host/pci_generic.c | 60 ++++++++++++++++++++++++++++++ 1 file changed, 60 insertions(+) diff --git a/drivers/bus/mhi/host/pci_generic.c b/drivers/bus/mhi/host/pci_= generic.c index 9938bb034c1c..b9b7dd8d9411 100644 --- a/drivers/bus/mhi/host/pci_generic.c +++ b/drivers/bus/mhi/host/pci_generic.c @@ -245,6 +245,63 @@ struct mhi_pci_dev_info { .channel =3D ch_num, \ } =20 +static const struct mhi_channel_config mhi_qcom_qdu100_channels[] =3D { + MHI_CHANNEL_CONFIG_UL(0, "LOOPBACK", 32, 2), + MHI_CHANNEL_CONFIG_DL(1, "LOOPBACK", 32, 2), + MHI_CHANNEL_CONFIG_UL_SBL(2, "SAHARA", 128, 1), + MHI_CHANNEL_CONFIG_DL_SBL(3, "SAHARA", 128, 1), + MHI_CHANNEL_CONFIG_UL(4, "DIAG", 64, 3), + MHI_CHANNEL_CONFIG_DL(5, "DIAG", 64, 3), + MHI_CHANNEL_CONFIG_UL(9, "QDSS", 64, 3), + MHI_CHANNEL_CONFIG_UL(14, "NMEA", 32, 4), + MHI_CHANNEL_CONFIG_DL(15, "NMEA", 32, 4), + MHI_CHANNEL_CONFIG_UL(16, "CSM_CTRL", 32, 4), + MHI_CHANNEL_CONFIG_DL(17, "CSM_CTRL", 32, 4), + MHI_CHANNEL_CONFIG_UL(40, "MHI_PHC", 32, 4), + MHI_CHANNEL_CONFIG_DL(41, "MHI_PHC", 32, 4), + MHI_CHANNEL_CONFIG_UL(46, "IP_SW0", 256, 5), + MHI_CHANNEL_CONFIG_DL(47, "IP_SW0", 256, 5), + MHI_CHANNEL_CONFIG_UL(48, "IP_SW1", 256, 6), + MHI_CHANNEL_CONFIG_DL(49, "IP_SW1", 256, 6), + MHI_CHANNEL_CONFIG_UL(50, "IP_SW2", 256, 7), + MHI_CHANNEL_CONFIG_DL(51, "IP_SW2", 256, 7), +}; + +static struct mhi_event_config mhi_qcom_qdu100_events[] =3D { + /* first ring is control+data ring */ + MHI_EVENT_CONFIG_CTRL(0, 64), + /* SAHARA dedicated event ring */ + MHI_EVENT_CONFIG_SW_DATA(1, 256), + /* Software channels dedicated event ring */ + MHI_EVENT_CONFIG_SW_DATA(2, 64), + MHI_EVENT_CONFIG_SW_DATA(3, 256), + MHI_EVENT_CONFIG_SW_DATA(4, 256), + /* Software IP channels dedicated event ring */ + MHI_EVENT_CONFIG_SW_DATA(5, 512), + MHI_EVENT_CONFIG_SW_DATA(6, 512), + MHI_EVENT_CONFIG_SW_DATA(7, 512), +}; + +static const struct mhi_controller_config mhi_qcom_qdu100_config =3D { + .max_channels =3D 128, + .timeout_ms =3D 120000, + .num_channels =3D ARRAY_SIZE(mhi_qcom_qdu100_channels), + .ch_cfg =3D mhi_qcom_qdu100_channels, + .num_events =3D ARRAY_SIZE(mhi_qcom_qdu100_events), + .event_cfg =3D mhi_qcom_qdu100_events, +}; + +static const struct mhi_pci_dev_info mhi_qcom_qdu100_info =3D { + .name =3D "qcom-lassen", + .fw =3D "qcom/lassen/xbl_s.melf", + .edl =3D "qcom/lassen/edl.mbn", + .edl_trigger =3D true, + .config =3D &mhi_qcom_qdu100_config, + .bar_num =3D MHI_PCI_DEFAULT_BAR_NUM, + .dma_data_width =3D 32, + .sideband_wake =3D false, +}; + static const struct mhi_channel_config modem_qcom_v1_mhi_channels[] =3D { MHI_CHANNEL_CONFIG_UL(4, "DIAG", 16, 1), MHI_CHANNEL_CONFIG_DL(5, "DIAG", 16, 1), @@ -822,6 +879,9 @@ static const struct pci_device_id mhi_pci_id_table[] = =3D { /* NETPRISMA FCUN69 (SDX6X) */ { PCI_DEVICE(PCI_VENDOR_ID_NETPRISMA, 0x1001), .driver_data =3D (kernel_ulong_t) &mhi_netprisma_fcun69_info }, + /* QDU100, x100-DU */ + { PCI_DEVICE(PCI_VENDOR_ID_QCOM, 0x0601), + .driver_data =3D (kernel_ulong_t)&mhi_qcom_qdu100_info }, { } }; MODULE_DEVICE_TABLE(pci, mhi_pci_id_table); --=20 2.34.1
