From 05af7bd2d75e5098021864d83fbb831111755fa0 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 8 May 2007 12:58:37 +1000 Subject: [POWERPC] MPIC U3/U4 MSI backend MPIC U3/U4 MSI backend. Based on code from Segher, heavily hacked by me. This only deals with MSI on U3/U4 MPICs, aka. CPC 9x5. If we find a U3/U4 then we enable this backend, ie. take over the ppc_md MSI hooks. We might need more elaborate logic in future to decide which backend is enabled. We need our own irq_chip so that we can do MSI masking/unmasking on the device itself. We also need to mask explicitly on shutdown to make sure we don't get bitten by lazy-disable semantics.
