This can lead to no-link, or incorrect speed conditions. >=20 > For example: >=20 > * If link is initially established with a 1G SFP, and later a 1G/10G > multispeed part is later installed, then the MAC link setup functions are > never called to change from 1000BASE-X to 10GBASE-R mode, and the link > stays running at the slower rate. >=20 > * If link is initially established with a 1G SFP, and later a 10G only > module is later installed, no link is established, since we are still > trasnsmitting in 1000BASE-X mode to a 10GBASE-R only partner. >=20 > Refactor the SFP ID/setup, and link setup code, to more closely match the > flow of the mainline kernel driver which does not have these issues. In > that driver a service task runs periodically to handle these operations > based on bit flags that have been set (usually via interrupt or userspace > request), and then get cleared once the requested subtask has been > completed. >=20 > Fixes: af75078fece ("first public release") > Cc: stable@dpdk.org >=20 So BIG change for new platform, DON'T CC to stable! > Signed-off-by: Stephen Douthit > Signed-off-by: Jeff Daly > --- > drivers/net/ixgbe/ixgbe_ethdev.c | 533 +++++++++++++++++++++++-------- > drivers/net/ixgbe/ixgbe_ethdev.h | 14 +- > 2 files changed, 410 insertions(+), 137 deletions(-) >=20 > diff --git a/drivers/net/ixgbe/ixgbe_ethdev.c b/drivers/net/ixgbe/ixgbe_e= thdev.c > index f31bbb7895..9e720eee47 100644 > --- a/drivers/net/ixgbe/ixgbe_ethdev.c > +++ b/drivers/net/ixgbe/ixgbe_ethdev.c > @@ -236,9 +236,6 @@ static int ixgbe_dev_interrupt_get_status(struct rte_= eth_dev *dev); > static int ixgbe_dev_interrupt_action(struct rte_eth_dev *dev); > static void ixgbe_dev_interrupt_handler(void *param); > static void ixgbe_dev_interrupt_delayed_handler(void *param); > -static void *ixgbe_dev_setup_link_thread_handler(void *param); > -static int ixgbe_dev_wait_setup_link_complete(struct rte_eth_dev *dev, > - uint32_t timeout_ms); >=20 > + /* TODO - Even for platforms where ixgbe_check_sfp_cage() gives a clear > + * status result, if there's no interrupts, or no interrupt for the SFP > + * cage present pin, even if other interrupts exist, then we still need > + * to poll here to set the flag. > + */ > +#ifndef RTE_EXEC_ENV_FREEBSD > + struct rte_pci_device *pci_dev =3D RTE_ETH_DEV_TO_PCI(dev); > + struct rte_intr_handle *intr_handle =3D pci_dev->intr_handle; > + if (rte_intr_allow_others(intr_handle)) { > + /* check if lsc interrupt is enabled */ > + if (dev->data->dev_conf.intr_conf.lsc) > + have_int =3D true; > + /* Check for loss of SFP */ > + /* TODO - For platforms that don't have this flag, do we need to set > + * NEED_SFP_SETUP on LSC if we're a SFP platform? > + */ > + if (hw->mac.type =3D=3D ixgbe_mac_X550EM_a && > + (eicr & IXGBE_EICR_GPI_SDP0_X550EM_a)) > + intr->flags |=3D IXGBE_FLAG_NEED_SFP_SETUP; > + > return 0; > } TODO ? > -- > 2.25.1
