Message-Id: <20230406173308.401924-6-kory.maincent@bootlin.com> Date: Thu, 6 Apr 2023 19:33:08 +0200 From: Köry Maincent <kory.maincent@...tlin.com> To: netdev@...r.kernel.org Cc: kuba@...nel.org, glipus@...il.com, maxime.chevallier@...tlin.com, vladimir.oltean@....com, vadim.fedorenko@...ux.dev, richardcochran@...il.com, gerhard@...leder-embedded.com, thomas.petazzoni@...tlin.com, krzysztof.kozlowski+dt@...aro.org, robh+dt@...nel.org, linux@...linux.org.uk, Kory Maincent <kory.maincent@...tlin.com> Subject: [PATCH net-next RFC v4 5/5] net: fix up drivers WRT phy time stamping From: Richard Cochran <richardcochran@...il.com> For "git bisect" correctness, this patch should be squashed in to the previous one, but it is broken out here for the purpose of review. I will also add the fix up of lan966x driver to validate the netdev notifier when the hwtstamp action will be converted to NDO. Signed-off-by: Richard Cochran <richardcochran@...il.com> Signed-off-by: Kory Maincent <kory.maincent@...tlin.com> --- Notes: I will add the lan966x driver update to verify the netdev notifer once the replacement to NDO by Max will be done. Also I don't have this hardware to test it, it will be useful if someone will be willing to test for me. drivers/net/ethernet/freescale/fec_main.c | 23 +++++++++----------- drivers/net/ethernet/mscc/ocelot_net.c | 21 +++++++++--------- drivers/net/ethernet/ti/cpsw_priv.c | 12 +++++------ drivers/net/ethernet/ti/netcp_ethss.c | 26 +++++------------------ 4 files changed, 31 insertions(+), 51 deletions(-) diff --git a/drivers/net/ethernet/freescale/fec_main.c b/drivers/net/ethernet/freescale/fec_main.c index f3b16a6673e2..bc4bfdad83ca 100644 --- a/drivers/net/ethernet/freescale/fec_main.c +++ b/drivers/net/ethernet/freescale/fec_main.c @@ -3213,22 +3213,19 @@ static int fec_enet_ioctl(struct net_device *ndev, struct ifreq *rq, int cmd) if (!netif_running(ndev)) return -EINVAL; - if (!phydev) - return -ENODEV; + switch (cmd) { + case SIOCSHWTSTAMP: + return fep->bufdesc_ex ? fec_ptp_set(ndev, rq) : + -EOPNOTSUPP; - if (fep->bufdesc_ex) { - bool use_fec_hwts = !phy_has_hwtstamp(phydev); - - if (cmd == SIOCSHWTSTAMP) { - if (use_fec_hwts) - return fec_ptp_set(ndev, rq); - fec_ptp_disable_hwts(ndev); - } else if (cmd == SIOCGHWTSTAMP) { - if (use_fec_hwts) - return fec_ptp_get(ndev, rq); - } + case SIOCGHWTSTAMP: + return fep->bufdesc_ex ? fec_ptp_get(ndev, rq) : + -EOPNOTSUPP; } + if (!phydev) + return -ENODEV; + return phy_mii_ioctl(phydev, rq, cmd); } diff --git a/drivers/net/ethernet/mscc/ocelot_net.c b/drivers/net/ethernet/mscc/ocelot_net.c index 21a87a3fc556..29f7a8a3a4d9 100644 --- a/drivers/net/ethernet/mscc/ocelot_net.c +++ b/drivers/net/ethernet/mscc/ocelot_net.c @@ -873,18 +873,19 @@ static int ocelot_ioctl(struct net_device *dev, struct ifreq *ifr, int cmd) struct ocelot *ocelot = priv->port.ocelot; int port = priv->port.index; - /* If the attached PHY device isn't capable of timestamping operations, - * use our own (when possible). - */ - if (!phy_has_hwtstamp(dev->phydev) && ocelot->ptp) { - switch (cmd) { - case SIOCSHWTSTAMP: - return ocelot_hwstamp_set(ocelot, port, ifr); - case SIOCGHWTSTAMP: - return ocelot_hwstamp_get(ocelot, port, ifr); - } + switch (cmd) { + case SIOCSHWTSTAMP: + return ocelot->ptp ? ocelot_hwstamp_set(ocelot, port, ifr) : + -EOPNOTSUPP; + + case SIOCGHWTSTAMP: + return ocelot->ptp ? ocelot_hwstamp_get(ocelot, port, ifr) : + -EOPNOTSUPP; } + if (!dev->phydev) + return -ENODEV; + return phy_mii_ioctl(dev->phydev, ifr, cmd); } diff --git a/drivers/net/ethernet/ti/cpsw_priv.c b/drivers/net/ethernet/ti/cpsw_priv.c index e966dd47e2db..cec4c65532c4 100644 --- a/drivers/net/ethernet/ti/cpsw_priv.c +++ b/drivers/net/ethernet/ti/cpsw_priv.c @@ -715,13 +715,11 @@ int cpsw_ndo_ioctl(struct net_device *dev, struct ifreq *req, int cmd) phy = cpsw->slaves[slave_no].phy; - if (!phy_has_hwtstamp(phy)) { - switch (cmd) { - case SIOCSHWTSTAMP: - return cpsw_hwtstamp_set(dev, req); - case SIOCGHWTSTAMP: - return cpsw_hwtstamp_get(dev, req); - } + switch (cmd) { + case SIOCSHWTSTAMP: + return cpsw_hwtstamp_set(dev, req); + case SIOCGHWTSTAMP: + return cpsw_hwtstamp_get(dev, req); } if (phy) diff --git a/drivers/net/ethernet/ti/netcp_ethss.c b/drivers/net/ethernet/ti/netcp_ethss.c index 2adf82a32bf6..6074ce13e130 100644 --- a/drivers/net/ethernet/ti/netcp_ethss.c +++ b/drivers/net/ethernet/ti/netcp_ethss.c @@ -2557,15 +2557,6 @@ static int gbe_txtstamp_mark_pkt(struct gbe_intf *gbe_intf, !gbe_dev->tx_ts_enabled) return 0; - /* If phy has the txtstamp api, assume it will do it. - * We mark it here because skb_tx_timestamp() is called - * after all the txhooks are called. - */ - if (phy_has_txtstamp(phydev)) { - skb_shinfo(p_info->skb)->tx_flags |= SKBTX_IN_PROGRESS; - return 0; - } - if (gbe_need_txtstamp(gbe_intf, p_info)) { p_info->txtstamp = gbe_txtstamp; p_info->ts_context = (void *)gbe_intf; @@ -2583,11 +2574,6 @@ static int gbe_rxtstamp(struct gbe_intf *gbe_intf, struct netcp_packet *p_info) if (p_info->rxtstamp_complete) return 0; - if (phy_has_rxtstamp(phydev)) { - p_info->rxtstamp_complete = true; - return 0; - } - if (gbe_dev->rx_ts_enabled) cpts_rx_timestamp(gbe_dev->cpts, p_info->skb); @@ -2821,13 +2807,11 @@ static int gbe_ioctl(void *intf_priv, struct ifreq *req, int cmd) struct gbe_intf *gbe_intf = intf_priv; struct phy_device *phy = gbe_intf->slave->phy; - if (!phy_has_hwtstamp(phy)) { - switch (cmd) { - case SIOCGHWTSTAMP: - return gbe_hwtstamp_get(gbe_intf, req); - case SIOCSHWTSTAMP: - return gbe_hwtstamp_set(gbe_intf, req); - } + switch (cmd) { + case SIOCGHWTSTAMP: + return gbe_hwtstamp_get(gbe_intf, req); + case SIOCSHWTSTAMP: + return gbe_hwtstamp_set(gbe_intf, req); } if (phy) -- 2.25.1
