2016-08-13net: thunderx: Support for 83xx mixed QLM/DLM configSunil Goutham
83xx has 4 BGX blocks and are enabled mixed QLM/DLM configs. BGX0/BGX1 are from QLM2/QLM3, BGX3 is DLM4 and BGX2 is split across DLM5 & DLM6. This patch adds support for BGX2's split config and also enables all 4 BGXs to be used. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-08-13net: thunderx: Add support for 16 LMACs of 83xxSunil Goutham
83xx will have 4 BGX blocks i.e 16 LMACs, to avoid changing the same with every platform, nicpf struct elements which track LMAC related info are now allocated runtime based on platform's max possible BGX count. Also fixed configuring min packet size for all LMAC's supported on a platform. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-08-13net: thunderx: Add RGMII interface type supportSunil Goutham
This patch adds RGX/RGMII interface type support to BGX driver. This type of interface is supported by 81xx SOC. CN81XX VNIC has 8 VFs and max possible LMAC interfaces are 9, hence RGMII interface will not work if all DLMs are in BGX mode and all 8 LMACs are enabled Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S.

2016-08-13net: thunderx: Add 81xx support to BGX driverSunil Goutham

2016-08-13net: thunderx: Support for different LMAC types within BGXSunil Goutham
On 88xx all LMACs in a BGX will be in same mode but on 81xx BGX can be split as two and there can be LMACs configured in different modes. These changes move lmac_type, lane2serdes fields into per lmac struct from BGX struct. Got rid of qlm_mode field which has become redundant with these changes. And now no of valid LMACs is read from CSRs configured by low level firmware and figuring out the same based on QLM mode is discarded Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S.

2016-08-13net: thunderx: Enable mailbox interrupts on 81xx/83xxSunil Goutham
88xx has 128 VFs, 81xx has 8 VFs and 83xx will have 32VFs. Made changes to PF driver such that mailbox interrupt enable registers are configuired based on number of VFs HW supports.

2016-08-13net: thunderx: Enable CQE_RX desc's extension fieldsSunil Goutham
Unlike 88xx, CQE_RX descriptor's tunnelling extension i.e CQE_RX2_S is always enabled on 81xx/83xx and HW does insert these fields into CQE_RX. As a result receive buffer addresses will now be present at 7th word of CQE_RX instead of 6th. Enable CQE_RX2_S on 88xx pass 2.x as well.

2016-08-13net: thunderx: Set queue count based on number of CPUsSunil Goutham
81xx has only 4 CPUs, so it doesn't make sense to initialize entire Qset i.e 8 queues by default. Made changes to queue initialization to init queues equal to number of CPUs or 8 queues whichever is lesser. Also this will be applicable to VMs with VNIC VF attached and having less VCPUs Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-03-16net: thunderx: Don't leak phy device references on -EPROBE_DEFER condition.David Daney
It is possible, although unlikely, that probing will find the phy_device for the first LMAC of a thunder BGX device, but then need to fail with -EPROBE_DEFER on a subsequent LMAC. In this case, we need to call put_device() on each of the phy_devices that were obtained, but will be unused due to returning -EPROBE_DEFER. Also, since we can break out of the probing loop early, we need to explicitly call of_node_put() outside of the loop. Signed-off-by: David Daney <david.daney@cavium.com> Signed-off-by: David S.

2015-12-08net: thunderx: Correctly distinguish between VF and LMAC countPavel Fedin
Commit bc69fdfc6c13 ("net: thunderx: Enable BGX LMAC's RX/TX only after VF is up") introduces lmac_cnt member and starts verifying VF number against it. This is plain wrong, and works only because currently we have hardcoded 1:1 mapping between VFs and LMACs, and in this case num_vf_en and lmac_cnt are always equal. However in future this may change, and the code will badly misbehave. The worst consequence of this is failure to deliver link status messages, causing VFs to go defunct because since commit 0b72a9a1060e ("net: thunderx: Switchon carrier only upon interface link up") VF will not fully bring itself up without it. This patch fixes the potential problem by doing VF number checks against the num_vf_en. Since lmac_cnt is not used anywhere else, it is removed. Additionally some duplicated code is factored out into nic_enable_vf() Signed-off-by: Pavel Fedin <p.fedin@samsung.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Enable or disable BGX LMAC's RX/TX based on corresponding VF's status. If otherwise, when multiple LMAC's physical link is up then packets from all LMAC's whose corresponding VF is not yet initialized will get forwarded to VF0. This is due to VNIC's default configuration where CPI, RSSI e.t.c point to VF0/QSET0/RQ0. This patch will prevent multiple copies of packets on VF0.

2015-12-02net: thunderx: Switchon carrier only upon interface link upSunil Goutham
Call netif_carrier_on() only if interface's link is up. Switching this on upon IFF_UP by default, is causing issues with ethernet channel bonding in LACP mode. Initial NETDEV_CHANGE notification was being skipped. Also fixed some issues with link/speed/duplex reporting via ethtool. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S.

2015-12-02net: thunderx: Set CQ timer threshold properlySunil Goutham
Properly set CQ timer threshold and also set it to 2us. With previous incorrect settings it was set to 0.5us which is too less. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-11-16net: thunder: Check for driver data in nicvf_remove()Pavel Fedin
In some cases the crash is caused by nicvf_remove() being called from outside. For example, if we try to feed the device to vfio after the probe has failed for some reason. So, move the check to better place. Signed-off-by: Pavel Fedin <p.fedin@samsung.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-11-15net: thunder: Fix crash upon shutdown after failed probePavel Fedin
If device probe fails, driver remains bound to the PCI device. However, driver data has been reset to NULL. This causes crash upon dereferencing it in nicvf_remove() Signed-off-by: Pavel Fedin <p.fedin@samsung.com> Signed-off-by: David S. Miller <davem@davemloft.net>
