With the msi_list and the msi_domain properties now being at the generic device level, it is starting to be relatively easy to offer a generic way of providing non-PCI MSIs. The two major hurdles with this idea are: - Lack of global ID that identifies a device: this is worked around by having a global ID allocator for each device that gets enrolled in the platform MSI subsystem - Lack of standard way to write the message in the generating device. This is solved by mandating driver code to provide a write_msg callback, so that everyone can have their own square wheel Apart from that, the API is fairly straightforward: - platform_msi_create_irq_domain creates an MSI domain that gets tagged with DOMAIN_BUS_PLATFORM_MSI - platform_msi_domain_alloc_irqs allocate MSIs for a given device, populating the msi_list - platform_msi_domain_free_irqs does what is written on the tin [ tglx: Created a seperate struct platform_msi_desc and added kerneldoc entries ] Signed-off-by: Marc Zyngier <[email protected]> Cc: <[email protected]> Cc: Yijing Wang <[email protected]> Cc: Ma Jun <[email protected]> Cc: Lorenzo Pieralisi <[email protected]> Cc: Duc Dang <[email protected]> Cc: Hanjun Guo <[email protected]> Cc: Bjorn Helgaas <[email protected]> Cc: Jiang Liu <[email protected]> Cc: Jason Cooper <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Thomas Gleixner <[email protected]>
