2024-03-04idpf: add idpf_virtchnl.hAlan Brady
idpf.h is quite heavy. We can reduce the burden a fair bit by introducing an idpf_virtchnl.h file. This mostly just moves function declarations but there are many of them. This also makes an attempt to group those declarations in a way that makes some sense instead of mishmashed.

2024-03-01ice: reorder disabling IRQ and NAPI in ice_qp_disMaciej Fijalkowski
ice_qp_dis() currently does things in very mixed way. Tx is stopped before disabling IRQ on related queue vector, then it takes care of disabling Rx and finally NAPI is disabled. Let us start with disabling IRQs in the first place followed by turning off NAPI. Then it is safe to handle queues. One subtle change on top of that is that even though ice_qp_ena() looks more sane, clear ICE_CFG_BUSY as the last thing there.

2024-02-20ice: Fix ASSERT_RTNL() warning during certain scenariosAmritha Nambiar
Commit 91fdbce7e8d6 ("ice: Add support in the driver for associating queue with napi") invoked the netif_queue_set_napi() call. This kernel function requires to be called with rtnl_lock taken, otherwise ASSERT_RTNL() warning will be triggered. ice_vsi_rebuild() initiating this call is under rtnl_lock when the rebuild is in response to configuration changes from external interfaces (such as tc, ethtool etc. which holds the lock). But, the VSI rebuild generated from service tasks and resets (PFR/CORER/GLOBR) is not under rtnl lock protection. Handle these cases as well to hold lock before the kernel call (by setting the 'locked' boolean to false). netif_queue_set_napi() is also used to clear previously set napi in the q_vector unroll flow. Handle this for locked/lockless execution paths.

2024-02-20ice: fix dpll and dpll_pin data access on PF resetArkadiusz Kubalewski
Do not allow to acquire data or alter configuration of dpll and pins through firmware if PF reset is in progress, this would cause confusing netlink extack errors as the firmware cannot respond or process the request properly during the reset time. Return (-EBUSY) and extack error for the user who tries access/modify the config of dpll/pin through firmware during the reset time. The PF reset and kernel access to dpll data are both asynchronous. It is not possible to guard all the possible reset paths with any determinictic approach. I.e., it is possible that reset starts after reset check is performed (or if the reset would be checked after mutex is locked), but at the same time it is not possible to wait for dpll mutex unlock in the reset flow. This is best effort solution to at least give a clue to the user what is happening in most of the cases, knowing that there are possible race conditions where the user could see a different error received from firmware due to reset unexpectedly starting.

E.g.: --do pin-set --json '{"id":2, "parent-device":{"parent-id":1, "state": 1 }}' This command will connect DPLL device with id 1 to output pin with id 2. When 'state_on_dpll_set' is called with the value 'DPLL_PIN_STATE_DISCONNECTED' (2) and the given DPLL is currently connected, then the output pin will be disabled. E.g: --do pin-set --json '{"id":2, "parent-device":{"parent-id":1, "state": 2 }}' This command will disable output pin with id 2 if DPLL device with ID 1 is connected to it; otherwise, the command is ignored.

2024-02-16i40e: Remove VEB recursionIvan Vecera
The VEB (virtual embedded switch) as a switch element can be connected according datasheet though its uplink to: - Physical port - Port Virtualizer (not used directly by i40e driver but can be present in MFP mode where the physical port is shared between PFs) - No uplink (aka floating VEB) But VEB uplink cannot be connected to another VEB and any attempt to do so results in: "i40e 0000:02:00.0: couldn't add VEB, err -EIO aq_err I40E_AQ_RC_ENOENT" that indicates "the uplink SEID does not point to valid element". Remove this logic from the driver code this way: 1) For debugfs only allow to build floating VEB (uplink_seid == 0) or main VEB (uplink_seid == mac_seid) 2) Do not recurse in i40e_veb_link_event() as no VEB cannot have sub-VEBs 3) Ditto for i40e_veb_rebuild() + simplify the function as we know that the VEB for rebuild can be only the main LAN VEB or some of the floating VEBs 4) In i40e_rebuild() there is no need to check veb->uplink_seid as the possible ones are 0 and MAC SEID 5) In i40e_vsi_release() do not take into account VEBs whose uplink is another VEB as this is not possible 6) Remove veb_idx field from i40e_veb as a VEB cannot have sub-VEBs Tested using i40e debugfs interface: 1) Initial state [root@cnb-03 net-next]# CMD="/sys/kernel/debug/i40e/0000:02:00.0/command" [root@cnb-03 net-next]# echo dump switch > $CMD [root@cnb-03 net-next]# dmesg -c [ 98.440641] i40e 0000:02:00.0: header: 3 reported 3 total [ 98.446053] i40e 0000:02:00.0: type=19 seid=392 uplink=160 downlink=16 [ 98.452593] i40e 0000:02:00.0: type=17 seid=160 uplink=2 downlink=0 [ 98.458856] i40e 0000:02:00.0: type=19 seid=390 uplink=160 downlink=16 2) Add floating VEB [root@cnb-03 net-next]# echo add relay > $CMD [root@cnb-03 net-next]# dmesg -c [ 122.745630] i40e 0000:02:00.0: added relay 162 [root@cnb-03 net-next]# echo dump switch > $CMD [root@cnb-03 net-next]# dmesg -c [ 136.650049] i40e 0000:02:00.0: header: 4 reported 4 total [ 136.655466] i40e 0000:02:00.0: type=19 seid=392 uplink=160 downlink=16 [ 136.661994] i40e 0000:02:00.0: type=17 seid=160 uplink=2 downlink=0 [ 136.668264] i40e 0000:02:00.0: type=19 seid=390 uplink=160 downlink=16 [ 136.674787] i40e 0000:02:00.0: type=17 seid=162 uplink=0 downlink=0 3) Add VMDQ2 VSI to this new VEB [root@cnb-03 net-next]# dmesg -c [ 168.351763] i40e 0000:02:00.0: added VSI 394 to relay 162 [ 168.374652] enp2s0f0np0v0: NIC Link is Up, 40 Gbps Full Duplex, Flow Control: None [root@cnb-03 net-next]# echo dump switch > $CMD [root@cnb-03 net-next]# dmesg -c [ 195.683204] i40e 0000:02:00.0: header: 5 reported 5 total [ 195.688611] i40e 0000:02:00.0: type=19 seid=394 uplink=162 downlink=16 [ 195.695143] i40e 0000:02:00.0: type=17 seid=162 uplink=0 downlink=0 [ 195.701410] i40e 0000:02:00.0: type=19 seid=392 uplink=160 downlink=16 [ 195.707935] i40e 0000:02:00.0: type=17 seid=160 uplink=2 downlink=0 [ 195.714201] i40e 0000:02:00.0: type=19 seid=390 uplink=160 downlink=16 4) Try to delete the VEB [root@cnb-03 net-next]# echo del relay 162 > $CMD [root@cnb-03 net-next]# dmesg -c [ 239.260901] i40e 0000:02:00.0: deleting relay 162 [ 239.265621] i40e 0000:02:00.0: can't remove VEB 162 with 1 VSIs left 5) Do PF reset and check switch status after rebuild [root@cnb-03 net-next]# echo pfr > $CMD [root@cnb-03 net-next]# echo dump switch > $CMD [root@cnb-03 net-next]# dmesg -c ...

2024-02-16i40e: Fix broken support for floating VEBsIvan Vecera
Although the i40e supports so-called floating VEB (VEB without an uplink connection to external network), this support is broken. This functionality is currently unused (except debugfs) but it will be used by subsequent series for switchdev mode slow-path. Fix this by following: 1) Handle correctly floating VEB (VEB with uplink_seid == 0) in i40e_reconstitute_veb() and look for owner VSI and create it only for non-floating VEBs and also set bridge mode only for such VEBs as the floating ones are using always VEB mode. 2) Handle correctly floating VEB in i40e_veb_release() and disallow its release when there are some VSIs. This is different from regular VEB that have owner VSI that is connected to VEB's uplink after VEB deletion by FW. 3) Fix i40e_add_veb() to handle 'vsi' that is NULL for floating VEBs. For floating VEB use 0 for downlink SEID and 'true' for 'default_port' parameters as per datasheet. 4) Fix 'add relay' command in i40e_dbg_command_write() to allow to create floating VEB by 'add relay 0 0' or 'add relay' Tested using debugfs: 1) Initial state [root@host net-next]# echo dump switch > $CMD [root@host net-next]# dmesg -c [ 173.701286] i40e 0000:02:00.0: header: 3 reported 3 total [ 173.706701] i40e 0000:02:00.0: type=19 seid=392 uplink=160 downlink=16 [ 173.713241] i40e 0000:02:00.0: type=17 seid=160 uplink=2 downlink=0 [ 173.719507] i40e 0000:02:00.0: type=19 seid=390 uplink=160 downlink=16 2) Add floating VEB [root@host net-next]# CMD="/sys/kernel/debug/i40e/0000:02:00.0/command" [root@host net-next]# echo add relay > $CMD [root@host net-next]# dmesg -c [ 245.551720] i40e 0000:02:00.0: added relay 162 [root@host net-next]# echo dump switch > $CMD [root@host net-next]# dmesg -c [ 276.984371] i40e 0000:02:00.0: header: 4 reported 4 total [ 276.989779] i40e 0000:02:00.0: type=19 seid=392 uplink=160 downlink=16 [ 276.996302] i40e 0000:02:00.0: type=17 seid=160 uplink=2 downlink=0 [ 277.002569] i40e 0000:02:00.0: type=19 seid=390 uplink=160 downlink=16 [ 277.009091] i40e 0000:02:00.0: type=17 seid=162 uplink=0 downlink=0 3) Add VMDQ2 VSI to this new VEB [root@host net-next]# echo add vsi 162 > $CMD [root@host net-next]# dmesg -c [ 332.314030] i40e 0000:02:00.0: added VSI 394 to relay 162 [ 332.337486] enp2s0f0np0v0: NIC Link is Up, 40 Gbps Full Duplex, Flow Control: None [root@host net-next]# echo dump switch > $CMD [root@host net-next]# dmesg -c [ 387.284490] i40e 0000:02:00.0: header: 5 reported 5 total [ 387.289904] i40e 0000:02:00.0: type=19 seid=394 uplink=162 downlink=16 [ 387.296446] i40e 0000:02:00.0: type=17 seid=162 uplink=0 downlink=0 [ 387.302708] i40e 0000:02:00.0: type=19 seid=392 uplink=160 downlink=16 [ 387.309234] i40e 0000:02:00.0: type=17 seid=160 uplink=2 downlink=0 [ 387.315500] i40e 0000:02:00.0: type=19 seid=390 uplink=160 downlink=16 4) Try to delete the VEB [root@host net-next]# echo del relay 162 > $CMD [root@host net-next]# dmesg -c [ 428.749297] i40e 0000:02:00.0: deleting relay 162 [ 428.754011] i40e 0000:02:00.0: can't remove VEB 162 with 1 VSIs left 5) Do PF reset and check switch status after rebuild [root@host net-next]# echo pfr > $CMD [root@host net-next]# echo dump switch > $CMD [root@host net-next]# dmesg -c [ 738.056172] i40e 0000:02:00.0: header: 5 reported 5 total [ 738.061577] i40e 0000:02:00.0: type=19 seid=394 uplink=162 downlink=16 [ 738.068104] i40e 0000:02:00.0: type=17 seid=162 uplink=0 downlink=0 [ 738.074367] i40e 0000:02:00.0: type=19 seid=392 uplink=160 downlink=16 [ 738.080892] i40e 0000:02:00.0: type=17 seid=160 uplink=2 downlink=0 [ 738.087160] i40e 0000:02:00.0: type=19 seid=390 uplink=160 downlink=16 6) Delete VSI and delete VEB [root@host net-next]# echo del vsi 394 > $CMD [root@host net-next]# echo del relay 162 > $CMD [root@host net-next]# echo dump switch > $CMD [root@host net-next]# dmesg -c [ 1233.081126] i40e 0000:02:00.0: deleting VSI 394 [ 1239.345139] i40e 0000:02:00.0: deleting relay 162 [ 1244.886920] i40e 0000:02:00.0: header: 3 reported 3 total [ 1244.892328] i40e 0000:02:00.0: type=19 seid=392 uplink=160 downlink=16 [ 1244.898853] i40e 0000:02:00.0: type=17 seid=160 uplink=2 downlink=0 [ 1244.905119] i40e 0000:02:00.0: type=19 seid=390 uplink=160 downlink=16 Reviewed-by: Wojciech Drewek <wojciech.drewek@intel.com> Signed-off-by: Ivan Vecera <ivecera@redhat.com> Tested-by: Pucha Himasekhar Reddy <himasekharx.reddy.pucha@intel.com> (A Contingent worker at Intel) Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

Seth reported that on his side XDP traffic can not survive a round of down/up against i40e interface. Dmesg output was telling us that we were not able to disable the very first XDP ring. That was due to the fact that in i40e_vsi_stop_rings() in a pre-work that is done before calling i40e_vsi_wait_queues_disabled(), XDP Tx queues were not taken into the account.

During devlink reload we can't take devl_lock (it's already taken) and in ice_probe() we have to lock it. Use devl_* variant of the API which does not acquire and release devl_lock.

2024-02-12ice: Add helper function ice_is_generic_macGrzegorz Nitka
E800 series devices have a couple of quirks: 1. Sideband control queues are not supported 2. The registers that the driver needs to program for the "Precision Time Protocol (PTP)" feature are different for E800 series devices compared to other devices supported by this driver. Both these require conditional logic based on the underlying device we are dealing with. The function ice_is_sbq_supported added by commit 8f5ee3c477a8 ("ice: add support for sideband messages") addresses (1). The same function can be used to address (2) as well but this just looks weird readability wise in cases that have nothing to do with sideband control queues: if (ice_is_sbq_supported(hw)) /* program register A */ else /* program register B */ For these cases, the function ice_is_generic_mac introduced by this patch communicates the idea/intention better.

2024-02-12ice: introduce new E825C devices familyGrzegorz Nitka
Introduce new Intel Ethernet E825C family devices. Add new PCI device IDs which are going to be supported by the driver: - 579C: Intel(R) Ethernet Connection E825-C for backplane - 579D: Intel(R) Ethernet Connection E825-C for QSFP - 579E: Intel(R) Ethernet Connection E825-C for SFP - 579F: Intel(R) Ethernet Connection E825-C for SGMII Add helper function ice_is_e825c() to verify if the running device belongs to E825C family.

2024-02-07net: intel: fix old compiler regressionsJesse Brandeburg
The kernel build regressions/improvements email contained a couple of issues with old compilers (in fact all the reports were on different architectures, but all gcc 5.5) and the FIELD_PREP() and FIELD_GET() conversions. They're all because an integer #define that should have been declared as unsigned, was shifted to the point that it could set the sign bit. The fix just involves making sure the defines use the "U" identifier on the constants to make sure they're unsigned. Should make the checkers happier. Confirmed with objdump before/after that there is no change to the binaries. Issues were reported as follows: ./drivers/net/ethernet/intel/ice/ice_base.c:238:7: note: in expansion of macro 'FIELD_GET' (FIELD_GET(GLINT_CTL_ITR_GRAN_25_M, regval) == ICE_ITR_GRAN_US)) ^ ./include/linux/compiler_types.h:435:38: error: call to '__compiletime_assert_1093' declared with attribute error: FIELD_GET: mask is not constant drivers/net/ethernet/intel/ice/ice_nvm.c:709:16: note: in expansion of macro ‘FIELD_GET’ orom->major = FIELD_GET(ICE_OROM_VER_MASK, combo_ver); ^ ./include/linux/compiler_types.h:435:38: error: call to ‘__compiletime_assert_796’ declared with attribute error: FIELD_GET: mask is not constant drivers/net/ethernet/intel/ice/ice_common.c:945:18: note: in expansion of macro ‘FIELD_GET’ u8 max_agg_bw = FIELD_GET(GL_PWR_MODE_CTL_CAR_MAX_BW_M, ^ ./include/linux/compiler_types.h:435:38: error: call to ‘__compiletime_assert_420’ declared with attribute error: FIELD_GET: mask is not constant drivers/net/ethernet/intel/i40e/i40e_dcb.c:458:8: note: in expansion of macro ‘FIELD_GET’ oui = FIELD_GET(I40E_LLDP_TLV_OUI_MASK, ouisubtype); ^ Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Closes: https://lore.kernel.org/lkml/d03e90ca-8485-4d1b-5ec1-c3398e0e8da@linux-m68k.org/ #i40e #ice Fixes: 62589808d73b ("i40e: field get conversion") Fixes: 5a259f8e0baf ("ice: field get conversion") Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Link: https://lore.kernel.org/r/20240206022906.2194214-1-jesse.brandeburg@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
