When preparing to\n> handle reset on the bus, the driver must stop all operations that can\n> lead to MMIO access in order to prevent HW errors. To accomplish this\n> introduce helper\n> idpf_reset_prepare() that gets called prior to FLR or when PCI error\n> is detected. Upon resume the recovery is done through the existing\n> reset path by starting the event task.\n> \n> The following callbacks are implemented:\n> .reset_prepare runs the first portion of the generic reset path\n> leading up to the part where we wait for the reset to complete.\n> .reset_done/resume runs the recovery part of the reset handling.\n> .error_detected is the callback dealing with PCI errors, similar to\n> the prepare call, we stop all operations, prior to attempting a\n> recovery.\n> .slot_reset is the callback attempting to restore the device, provided\n> a PCI reset was initiated by the AER driver.\n> \n> Whereas previously the init logic guaranteed netdevs during reset, the\n> addition of idpf_detach_and_close() to the PCI callbacks flow makes it\n> possible for the function to be called without netdevs. Add check to\n> avoid NULL pointer dereference in that case.\n> \n> Co-developed-by: Alan Brady \n> Signed-off-by: Alan Brady \n> Signed-off-by: Emil Tantilov \n> Reviewed-by: Jay Bhat \n> Reviewed-by: Madhu Chittim \n> ---\n> drivers/net/ethernet/intel/idpf/idpf.h | 3 +\n> drivers/net/ethernet/intel/idpf/idpf_lib.c | 13 ++-\n> drivers/net/ethernet/intel/idpf/idpf_main.c | 112 ++++++++++++++++++++\n> 3 files changed, 126 insertions(+), 2 deletions(-)\n> \n> diff --git a/drivers/net/ethernet/intel/idpf/idpf.h\n> b/drivers/net/ethernet/intel/idpf/idpf.h\n> index 1d0e32e47e87..164d2f3e233a 100644\n> --- a/drivers/net/ethernet/intel/idpf/idpf.h\n> +++ b/drivers/net/ethernet/intel/idpf/idpf.h\n> @@ -88,6 +88,7 @@ enum idpf_state {\n> * @IDPF_REMOVE_IN_PROG: Driver remove in progress\n> * @IDPF_MB_INTR_MODE: Mailbox in interrupt mode\n> * @IDPF_VC_CORE_INIT: virtchnl core has been init\n> + * @IDPF_PCI_CB_RESET: Reset via the PCI callbacks\n> * @IDPF_FLAGS_NBITS: Must be last\n> */\n> enum idpf_flags {\n> @@ -97,6 +98,7 @@ enum idpf_flags {\n> \tIDPF_REMOVE_IN_PROG,\n> \tIDPF_MB_INTR_MODE,\n> \tIDPF_VC_CORE_INIT,\n\n...\n\n> +/**\n> + * idpf_pci_err_resume - Resume operations after PCI error recovery\n> + * @pdev: PCI device struct\n> + */\n> +static void idpf_pci_err_resume(struct pci_dev *pdev) {\n> +\tstruct idpf_adapter *adapter = pci_get_drvdata(pdev);\n> +\n> +\t/* Force a PFR when resuming from PCI error. */\n> +\tif (test_and_set_bit(IDPF_PCI_CB_RESET, adapter->flags))\n> +\t\tadapter->dev_ops.reg_ops.trigger_reset(adapter,\n> IDPF_HR_FUNC_RESET);\nYou say \"Force a PFR\", but PFR is only triggered on the AER path, not on the FLR path.\n\nEverything else looks fine\nReviewed-by: Aleksandr Loktionov \n\n> +\n> +\tqueue_delayed_work(adapter->vc_event_wq,\n> +\t\t\t &adapter->vc_event_task,\n> +\t\t\t msecs_to_jiffies(300));\n> +}\n\n...\n\n> };\n> module_pci_driver(idpf_driver);\n> --\n> 2.37.3","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","intel-wired-lan@lists.osuosl.org"],"Delivered-To":["patchwork-incoming@legolas.ozlabs.org","intel-wired-lan@lists.osuosl.org"],"Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=osuosl.org header.i=@osuosl.org header.a=rsa-sha256\n header.s=default header.b=drarb05r;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=osuosl.org\n (client-ip=140.211.166.136;
