Pcie can an endpoint initiate a conversation
SpletSo, no, the endpoint will NOT use it's own BAR in TLP requests - that would be rather pointless - why would one initiate a PCIE Bus cycle access to one of it's own registers? … Splet06. maj 2024 · PCI-Express only supports MSI interrupts to be sent from Endpoint to Root Complex. I would like to "send interrupts" to a PCI Endpoint using some non-standard methods like exposing the interrupt controller's registers to a PCI BAR. This BAR can then be accessed by another Endpoint to raise an interrupt.
