Storing the platform private data in a MSI descriptor is sloppy at best. The data belongs to the device and not to the descriptor. Add a pointer to struct msi_device_data and store the pointer there.

Thomas Gleixner authored
The MSI core will introduce runtime allocation of MSI related data. This data will be devres managed and has to be set up before enabling PCI/MSI[-X]. This would introduce an ordering issue vs. pcim_release(). The setup order is: pcim_enable_device() devres_alloc(pcim_release...); ... pci_irq_alloc() msi_setup_device_data() devres_alloc(msi_device_data_release, ...) and once the device is released these release functions are invoked in the opposite order: msi_device_data_release() ... pcim_release() pci_disable_msi[x]() which is obviously wrong, because pci_disable_msi[x]() requires the MSI data to be available to tear down the MSI[-X] interrupts. Remove the MSI[-X] teardown from pcim_release() and add an explicit action to be installed on the attempt of enabling PCI/MSI[-X]. This allows the MSI core data allocation to be ordered correctly in a subsequent step.

There are quite some places which retrieve the first MSI descriptor to evaluate whether the setup is for MSI or MSI-X. That's required because pci_dev::msi[x]_enabled is only set when the setup completed successfully. There is no real reason why msi[x]_enabled can't be set at the beginning of the setup sequence and cleared in case of a failure. Implement that so the MSI descriptor evaluations can be converted to simple property queries.

PCI_MSIX_FLAGS_MASKALL is set in the MSI-X control register at MSI-X interrupt setup time. It's cleared on success, but the error handling path only clears the PCI_MSIX_FLAGS_ENABLE bit. That's incorrect as the reset state of the PCI_MSIX_FLAGS_MASKALL bit is zero. That can be observed via lspci: Capabilities: [b0] MSI-X: Enable- Count=67 Masked+ Clear the bit in the error path to restore the reset state.

Masking all unused MSI-X entries is done to ensure that a crash kernel starts from a clean slate, which correponds to the reset state of the device as defined in the PCI-E specificion 3.0 and later: Vector Control for MSI-X Table Entries -------------------------------------- "00: Mask bit: When this bit is set, the function is prohibited from sending a message using this MSI-X Table entry. ... This bit’s state after reset is 1 (entry is masked)." A Marvell NVME device fails to deliver MSI interrupts after trying to enable MSI-X interrupts due to that masking. It seems to take the MSI-X mask bits into account even when MSI-X is disabled. While not specification compliant, this can be cured by moving the masking into the success path, so that the MSI-X table entries stay in device reset state when the MSI-X setup fails.
