Re: [PATCH 0/5] PCI: endpoint: Add support for additional notifiers

Hi Mani,
Adding more notifier types will surely help but I believe the list is not exhaustive. What you are trying here is to pass various vendor-specific epc interrupts to EPF driver. That can be taken care by a single notifier interface as well, "pci_epc_custom_notify" from your implementation. This also requires to have pre-defined values of "data" argument to standardize the interface.

your thoughts?

Thanks,
Om

Hello,

This series adds support for additional notifiers in the PCI endpoint
framework. The notifiers LINK_DOWN, BME, PME, and D_STATE are generic
for all PCI endpoints but there is also a custom notifier (CUSTOM) added
to pass the device/vendor specific events to EPF from EPC.

The example usage of all notifiers is provided in the commit description.

Thanks,
Mani
