* x86: kvm: fix build errorLinus Torvalds2024-09-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cpu_emergency_register_virt_callback() function is used unconditionally by the x86 kvm code, but it is declared (and defined) conditionally: #if IS_ENABLED(CONFIG_KVM_INTEL) || IS_ENABLED(CONFIG_KVM_AMD) void cpu_emergency_register_virt_callback(cpu_emergency_virt_cb *callback); ... leading to a build error when neither KVM_INTEL nor KVM_AMD support is enabled: arch/x86/kvm/x86.c: In function ‘kvm_arch_enable_virtualization’: arch/x86/kvm/x86.c:12517:9: error: implicit declaration of function ‘cpu_emergency_register_virt_callback’ [-Wimplicit-function-declaration] 12517 | cpu_emergency_register_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ arch/x86/kvm/x86.c: In function ‘kvm_arch_disable_virtualization’: arch/x86/kvm/x86.c:12522:9: error: implicit declaration of function ‘cpu_emergency_unregister_virt_callback’ [-Wimplicit-function-declaration] 12522 | cpu_emergency_unregister_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fix the build by defining empty helper functions the same way the old cpu_emergency_disable_virtualization() function was dealt with for the same situation. Maybe we could instead have made the call sites conditional, since the callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak fallback. I'll leave that to the kvm people to argue about, this at least gets the build going for that particular config.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Use of_property_match_string() instead of open-coding the search. With this, of_get_property() can be removed as there is no need to check for "mbox-names" presence first.

The benefit is that events of interest are still logged and the entire trace buffer is not dumped with extraneous logging information when using default lpfc_log_verbose driver parameter settings. Also, delete the keyword "fail" from such log messages as they aren't really causes for concern. The log messages are more for warnings to a SAN admin about SAN activity.

The issue is that when the FLOGI completion routine executes, the fabric ndlp could already be freed because of the final kref put from the dev_loss_tmo handler. Fix by early returning before the ndlp kref put if the ndlp is deemed a candidate for NLP_IN_RECOV_POST_DEV_LOSS in the FLOGI completion routine.

The issue is in lpfc_els_flush_cmd(), where the driver attempts to recover outstanding ELS sgls when walking the txcmplq. Only CMD_ELS_REQUEST64_CRs and CMD_GEN_REQUEST64_CRs are added to the abort and cancel lists. A check for CMD_XMIT_ELS_RSP64_WQE is missing in order to recover LS_ACC usages of the phba->sli4_hba.lpfc_els_sgl_list too. Fix by adding CMD_XMIT_ELS_RSP64_WQE as part of the txcmplq walk when adding WQEs to the abort and cancel list in lpfc_els_flush_cmd(). Also, update naming convention from CRs to WQEs.

This causes an unnecessary delay of 510 secs in the overall firmware initialization sequence. Poll the controller state periodically (every 100 milliseconds) while waiting for the controller to come out of the mentioned transient states. Once the controller transits out of the transient states, come out of the wait loop.
