powerpc/powernv: Call opal_pci_poll() if needed When issuing PHB reset, OPAL API opal_pci_poll() is called to drive the state machine in OPAL forward. However, we needn't always call the function under some circumstances like reset deassert. This avoids calling opal_pci_poll() when OPAL_SUCCESS is returned from opal_pci_reset(). Except the overhead introduced by additional one unnecessary OPAL call, I didn't run into real issue because of this.

Revert "powerpc/powernv: Exclude root bus in pnv_pci_reset_secondary_bus()" This reverts commit c8ceacc22bce95d3a9cff198c9c27a30105a16b8. Gavin says: I missed the fact that it affects the PCI passthrou path as reported by Alexey: When passing GPU (0003:01:00.0) which seats behind the root port, the reset request is routed to skiboot in original code. In skiboot, the link bouncing events are masked during the reset. So we don't see EEH (freeze all) error even link bouncing happens. With the changes included, the reset is done by kernel and the link bouncing events aren't masked by altering content of PHB3 (or P7IOC) specific hardware registers which are invisible to kernel (skiboot hides the hardware specific). It means the link bouncing is seen by the root port and it causes a EEH (freeze all) error. The PCI passthrough on GPU device cannot work.

powerpc/powernv: Support PCI config restore for VFs After PE reset, OPAL API opal_pci_reinit() is called on all devices contained in the PE to reinitialize them. While skiboot is not aware of VFs, we have to implement the function in kernel to reinitialize VFs after reset on PE for VFs. In this patch, two functions pnv_pci_fixup_vf_mps() and pnv_eeh_restore_vf_config() both manipulate the MPS of the VF, since for a VF it has three cases. 1. Normal creation for a VF In this case, pnv_pci_fixup_vf_mps() is called to make the MPS a proper value compared with its parent. 2. EEH recovery without VF removed In this case, MPS is stored in pci_dn and pnv_eeh_restore_vf_config() is called to restore it and reinitialize other part. 3. EEH recovery with VF removed In this case, VF will be removed then re-created. Both functions are called. First pnv_pci_fixup_vf_mps() is called to store the proper MPS to pci_dn and then pnv_eeh_restore_vf_config() is called to do proper thing. This introduces two functions: pnv_pci_fixup_vf_mps() to fixup the VF's MPS to make sure it is equal to parent's and store this value in pci_dn for future use. pnv_eeh_restore_vf_config() to re-initialize on VF by restoring MPS, disabling completion timeout, enabling SERR, etc. Signed-off-by: Wei Yang <weiyang@linux.vnet.ibm.com> Acked-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

powerpc/eeh: Fix stale cached primary bus When PE is created, its primary bus is cached to pe->bus. At later point, the cached primary bus is returned from eeh_pe_bus_get(). However, we could get stale cached primary bus and run into kernel crash in one case: full hotplug as part of fenced PHB error recovery releases all PCI busses under the PHB at unplugging time and recreate them at plugging time. pe->bus is still dereferencing the PCI bus that was released. This adds another PE flag (EEH_PE_PRI_BUS) to represent the validity of pe->bus. pe->bus is updated when its first child EEH device is online and the flag is set. Before unplugging in full hotplug for error recovery, the flag is cleared.

powerpc/eeh-powernv: Fix unbalanced IRQ warning pnv_eeh_next_error() re-enables the eeh opal event interrupt but it gets called from a loop if there are more outstanding events to process, resulting in a warning due to enabling an already enabled interrupt. Instead the interrupt should only be re-enabled once the last outstanding event has been processed.

powerpc/eeh: Dump PHB diag-data for non-existing PE When detecting EEH error on non-existing PE, including the reserved one, the PE is simply unfrozen without dumping the PHB diag-data, which is useful for locating the root cause of the EEH error. The patch dumps the PHB diag-data when non-existing PE reports error. Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
