Subject: MSI to memory?
Date: Thu, 1 Jul 2004 12:15:59 -0600 [thread overview]
Message-ID: <200407011215.59723.bjorn.helgaas@hp.com> (raw)
The conventional use of MSI is for a PCI adapter to generate processor
interrupts by writing to a local APIC. But I've seen some things
that lead me to believe it would also allow an adapter to write to
things other than a local APIC, i.e., to memory.
If so, is that a useful capability that should be exposed through
the Linux MSI interface?
