* PCI: Use positive flags in pci_alloc_irq_vectors()Christoph Hellwig2016-08-161-14/+10
| | | | | | | | | | | | | | | | | | Instead of passing negative flags like PCI_IRQ_NOMSI to prevent use of certain interrupt types, pass positive flags like PCI_IRQ_LEGACY, PCI_IRQ_MSI, etc., to specify the acceptable interrupt types. This is based on a number of pending driver conversions that just happend to be a whole more obvious to read this way, and given that we have no users in the tree yet it can still easily be done. I've also added a PCI_IRQ_ALL_TYPES catchall to keep the case of accepting all interrupt types very simple.

* PCI: Spread interrupt vectors in pci_alloc_irq_vectors()Christoph Hellwig2016-07-211-0/+4
| | | | | | | | | | | | | | | | | | Set the affinity_mask in the PCI device before allocating vectors so that the affinity can be propagated through the MSI descriptor structures to the core IRQ code. To facilitate this, new __pci_enable_msi_range() and __pci_enable_msix_range() helpers are factored out of their not prefixed variants which assigning the new IRQ affinity mask in the PCI device so that the low-level interrupt code can perform the interrupt affinity assignment and do node-local allocations. A new PCI_IRQ_NOAFFINITY flag is added to pci_alloc_irq_vectors() so that this function can also be used by drivers that don't wish to use the automatic affinity assignment.

| | | | | | | | | | | | | Add a function to allocate and free a range of interrupt vectors, using MSI-X, MSI or legacy vectors (in that order) based on the capabilities of the underlying device and PCIe complex. Additionally a new helper is provided to get the Linux IRQ number for given device-relative vector so that the drivers don't need to allocate their own arrays to keep track of the vectors for the multi vector MSI-X case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IRQF_DISABLED is a NOOP and scheduled to be removed. According to Ingo Molnar in commit e58aa3d2d0cc01ad8d6f7f640a0670433f794922 (genirq: Run irq handlers with interrupts disabled), running IRQ handlers with interrupts enabled can cause stack overflows when the interrupt line of the issuing device is still active. This patch removes IRQF_DISABLED from this documentation. It was mentioned to be a solution to avoid deadlocks when a device uses multiple interrupts. As the flag is a NOOP this solution does not work anymore. Signed-off-by: Valentin Rothberg <Valentin.Rothberg@lip6.fr> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

It also adds pci_enable_msix_range(), which supersedes the pci_enable_msix() MSI-X interface. The old interfaces have three categories of return values: negative: failure; caller should not retry positive: failure; value indicates number of interrupts that *could* have been allocated, and caller may retry with a smaller request zero: success; at least as many interrupts allocated as requested It is error-prone to handle these three cases correctly in drivers. The new functions return either a negative error code or a number of successfully allocated MSI/MSI-X interrupts, which is expected to lead to clearer device driver code. pci_enable_msi(), pci_enable_msi_block() and pci_enable_msix() still exist unchanged, but are deprecated and may be removed after callers are updated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed that when I inject a fatal error to an endpoint via aer-inject, aer_root_reset() is called as reset_link for a downstream port at upstream of the endpoint: pcieport 0000:00:06.0: AER: Uncorrected (Fatal) error received: id=5401 : pcieport 0000:52:02.0: Root Port link has been reset It externally appears to be working, but internally issues some accesses to PCI_ERR_ROOT_COMMAND/STATUS registers that is for root port so not available on downstream port. This patch introduces default_downstream_reset_link that is a version of aer_root_reset() with no accesses to root port's register. It is used for downstream ports that has no reset_link function its specific. This patch also updates related description in pcieaer-howto.txt. Some minor fixes are included.
