* sdk_dpaa: What to do with tail queue drop?Sebastian Huber2018-01-231-1/+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.

| | | | | | Translate address in of_address_to_resource(). Update #3277.

* dpaa: Reduce receive buffer seedSebastian Huber2017-10-231-0/+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().
* dpaa: Improve QMan portal initializationSebastian Huber2017-10-231-51/+61
| | | | Be less dependent on the device tree content.
* dpaa: Reduce PFDR space from 32MiB to 16MiBSebastian Huber2017-10-231-1/+1

* dpaa: Add "libbsd,dedicated-portal" to QMan portalsSebastian Huber2017-10-237-0/+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"; }; }; }; };
* dpaa: Add "libbsd,dequeue" to QMan portalsSebastian Huber2017-10-231-13/+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"; }; }; };
* dpaa: Set portal interrupt affinitySebastian Huber2017-10-232-0/+32

| | | | Linux baseline 6f7da290413ba713f0cdd9ff1a2a9bb129ef4f6c (v4.12).

* soc/qbman: Simplify bman_release()Sebastian Huber2017-10-231-9/+6
| | | | | | Get the affine portal only once for the complete transaction. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* soc/qman: Do not enable stashing without PAMUSebastian Huber2017-10-231-0/+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>
* qman_api.c: Prevent false clearing of IRQ statusSebastian Huber2017-10-231-2/+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.
* dpaa: Disable QMAN_VOLATILE_FLAG_WAIT_INTSebastian Huber2017-10-232-0/+6
