MSI support in Genode

[Jilong Kuang]

Hello Sebastian,

I'm trying to understand the current IRQ framework in Genode with regard to Fiasco.OC kernel. Could you briefly explain the role of Genode::Interrupt_handler and Genode::Irq_proxy_component threads?

Thank you very much!

Best regards,
Jilong

Unfortunately there is no MSI support in Genode's IRQ session as of now, therefore no sample code also. Currently we have shared IRQ support for Fiasco.OC, Nova, and OKl4. Would that solve your issue or do you have other needs that strictly require MSI support?

Additionally support for MSIs is on our road map and may evolve through the course of this year. But that heavily depends on our working schedule, which happened to change quite often in the past. So I cannot tell when, but MSI support will be implemented eventually.

Regards,

Sebastian
