2019-04-11Update due to API changesSebastian Huber4-5/+5
2018-09-21Update to FreeBSD head 2018-06-01Sebastian Huber1-1/+1
Git mirror commit fb63610a69b0eb7f69a201ba05c4c1a7a2739cf9. Update #3472.
2018-01-23sdk_dpaa: What to do with tail queue drop?Sebastian Huber1-1/+1
The issue is this: static int dpaa_eth_macless_probe(struct platform_device *_of_dev) { [...] INIT_LIST_HEAD(&priv->dpa_fq_list); err = dpa_fq_probe_macless(dev, &priv->dpa_fq_list, RX); if (!err) err = dpa_fq_probe_macless(dev, &priv->dpa_fq_list, TX); if (err < 0) goto fq_probe_failed; [...] /* Add the FQs to the interface, and make them active */ /* For MAC-less devices we only get here for RX frame queues * initialization, which are the TX queues of the other * partition. * It is safe to rely on one partition to set the FQ taildrop * threshold for the TX queues of the other partition * because the ERN notifications will be received by the * partition doing qman_enqueue. */ err = dpa_fqs_init(dev, &priv->dpa_fq_list, true); if (err < 0) goto fq_alloc_failed; [...] The priv->dpa_fq_list contains a list of FQ_TYPE_RX_PCD and FQ_TYPE_TX items. I don't understand what the "For MAC-less devices we only get here for RX frame queues initialization" means in this context. The td_enable == true in dpa_fqs_init(). So, we have: int dpa_fq_init(struct dpa_fq *dpa_fq, bool td_enable) { [...] if (dpa_fq->fq_type == FQ_TYPE_TX || dpa_fq->fq_type == FQ_TYPE_TX_CONFIRM || dpa_fq->fq_type == FQ_TYPE_TX_CONF_MQ) { [...] initfq.we_mask |= QM_INITFQ_WE_OAC; [...] } if (td_enable) { initfq.we_mask |= QM_INITFQ_WE_TDTHRESH; qm_fqd_taildrop_set(&initfq.fqd.td, DPA_FQ_TD, 1); initfq.fqd.fq_ctrl = QM_FQCTRL_TDE; } The td_enable == true && dpa_fq->fq_type == FQ_TYPE_TX causes later: int qman_init_fq(struct qman_fq *fq, u32 flags, struct qm_mcc_initfq *opts) { [...] if (opts && (opts->we_mask & QM_INITFQ_WE_OAC)) { /* And can't be set at the same time as TDTHRESH */ if (opts->we_mask & QM_INITFQ_WE_TDTHRESH) return -EINVAL; } This aborts the initialization of the MAC-less driver. I don't understand why this path doesn't happen on the SDK Linux system. Update #3277.

2017-10-23dpaa: Reduce receive buffer seedSebastian Huber1-0/+4
Seed the receive buffers of each affine software portal only with 8 mclusters (16KiB) and not 128 (256KiB). We have processor count affine software portals, see dpaa_bp_seed().
2017-10-23dpaa: Improve QMan portal initializationSebastian Huber1-51/+61
Be less dependent on the device tree content.

2017-10-23dpaa: Add "libbsd,dedicated-portal" to QMan portalsSebastian Huber7-0/+113
By default, the network interfaces use a pool channel, see dpaa_get_channel() in dpaa_eth_priv_probe(). To enable a dedicated QMan software portal, use libbsd,dedicated-portal = "enabled";. This option is useful for special purpose 10Gbit/s Ethernet processing. / { soc: soc@ffe000000 { fman0: fman@400000 { enet7: ethernet@f2000 { libbsd,dedicated-portal = "enabled"; }; }; }; };
2017-10-23dpaa: Add "libbsd,dequeue" to QMan portalsSebastian Huber1-13/+32
The dequeue support for processor affine QMan portals may be explicitly disabled. The dequeue support is responsible for receiving frames and completion of frame transmission, e.g. buffer recycling. Without at least one enabled dequeue support, there will be no networking. / { qman-portals@ff6000000 { qman-portal@0 { libbsd,dequeue = "disabled"; }; }; };

Get the affine portal only once for the complete transaction. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
2017-10-23soc/qman: Do not enable stashing without PAMUSebastian Huber1-0/+2
Do not enable stashing in the QMan software portal configuration (QCSPi_CFG[RE, SE]) in case the PAMU support is not configured. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
2017-10-23qman_api.c: Prevent false clearing of IRQ statusSebastian Huber1-2/+4
Adding (p->irq_sources & ~QM_PIRQ_CSCI) to the clear mask means for example we clear the QM_PIRQ_EQCI unconditionally. This is a problem in case this interrupt happens after the read of the interrupt status and before the interrupt status clear.
