From 42a63a26cfe02dc91a47c8dba60ca2aae1fa1e2a Mon Sep 17 00:00:00 2001 From: ian Date: Tue, 13 May 2014 17:12:07 +0000 Subject: MFC r256870, r256898, r256899, r256900 (by nwhitehorn): Standards-conformance and code deduplication: - Use bus reference phandles in place of FDT offsets as IRQ domain keys - Unify the identical macio/fdt/mambo OpenPIC drivers into one - Be more forgiving (following ePAPR) about what we need from the device tree to identify an OpenPIC - Correctly map all IRQs into an interrupt domain - Set IRQ_*_CONFORM for interrupts on an unknown PIC type instead of failing attachment for that device. Allow lots of interrupts (useful on multi-domain platforms) and do not set device_quiet() on all devices attached under nexus(4). --- sys/conf/files.powerpc | 4 +- sys/dev/cfi/cfi_bus_nexus.c | 15 ++- sys/dev/fdt/fdt_common.c | 30 +++--- sys/dev/fdt/fdt_pci.c | 2 +- sys/dev/fdt/fdt_powerpc.c | 3 +- sys/dev/fdt/fdtbus.c | 6 +- sys/dev/ofw/ofw_fdt.c | 2 +- sys/powerpc/mambo/mambo_openpic.c | 179 ----------------------------------- sys/powerpc/ofw/openpic_ofw.c | 129 +++++++++++++++++++++++++ sys/powerpc/powermac/openpic_macio.c | 110 --------------------- sys/powerpc/powerpc/openpic_fdt.c | 93 ------------------ 11 files changed, 167 insertions(+), 406 deletions(-) delete mode 100644 sys/powerpc/mambo/mambo_openpic.c create mode 100644 sys/powerpc/ofw/openpic_ofw.c delete mode 100644 sys/powerpc/powermac/openpic_macio.c delete mode 100644 sys/powerpc/powerpc/openpic_fdt.c diff --git a/sys/conf/files.powerpc b/sys/conf/files.powerpc index f97bde6..8953375 100644 --- a/sys/conf/files.powerpc +++ b/sys/conf/files.powerpc @@ -128,7 +128,6 @@ powerpc/mambo/mambocall.S optional mambo powerpc/mambo/mambo.c optional mambo powerpc/mambo/mambo_console.c optional mambo powerpc/mambo/mambo_disk.c optional mambo -powerpc/mambo/mambo_openpic.c optional mambo powerpc/mpc85xx/atpic.c optional mpc85xx isa powerpc/mpc85xx/ds1553_bus_fdt.c optional ds1553 fdt powerpc/mpc85xx/ds1553_core.c optional ds1553 @@ -147,6 +146,7 @@ powerpc/ofw/ofw_syscons.c optional sc aim powerpc/ofw/ofwcall32.S optional aim powerpc powerpc/ofw/ofwcall64.S optional aim powerpc64 powerpc/ofw/ofwmagic.S optional aim +powerpc/ofw/openpic_ofw.c optional aim | fdt powerpc/ofw/rtas.c optional aim powerpc/powermac/ata_kauai.c optional powermac ata | powermac atamacio powerpc/powermac/ata_macio.c optional powermac ata | powermac atamacio @@ -162,7 +162,6 @@ powerpc/powermac/kiic.c optional powermac kiic powerpc/powermac/macgpio.c optional powermac pci powerpc/powermac/macio.c optional powermac pci powerpc/powermac/nvbl.c optional powermac nvbl -powerpc/powermac/openpic_macio.c optional powermac pci powerpc/powermac/platform_powermac.c optional powermac powerpc/powermac/powermac_thermal.c optional powermac powerpc/powermac/pswitch.c optional powermac pswitch @@ -200,7 +199,6 @@ powerpc/powerpc/mmu_if.m standard powerpc/powerpc/mp_machdep.c optional smp powerpc/powerpc/nexus.c standard powerpc/powerpc/openpic.c standard -powerpc/powerpc/openpic_fdt.c optional fdt powerpc/powerpc/pic_if.m standard powerpc/powerpc/pmap_dispatch.c standard powerpc/powerpc/platform.c standard diff --git a/sys/dev/cfi/cfi_bus_nexus.c b/sys/dev/cfi/cfi_bus_nexus.c index 4e1fa4e..a87ee14 100644 --- a/sys/dev/cfi/cfi_bus_nexus.c +++ b/sys/dev/cfi/cfi_bus_nexus.c @@ -50,14 +50,25 @@ __FBSDID("$FreeBSD$"); static int cfi_nexus_probe(device_t dev) { + return (BUS_PROBE_NOWILDCARD); +} + +static int +cfi_nexus_attach(device_t dev) +{ + int error; + + error = cfi_probe(dev); + if (error != 0) + return (error); - return cfi_probe(dev); + return cfi_attach(dev); } static device_method_t cfi_nexus_methods[] = { /* device interface */ DEVMETHOD(device_probe, cfi_nexus_probe), - DEVMETHOD(device_attach, cfi_attach), + DEVMETHOD(device_attach, cfi_nexus_attach), DEVMETHOD(device_detach, cfi_detach), {0, 0} diff --git a/sys/dev/fdt/fdt_common.c b/sys/dev/fdt/fdt_common.c index dad4297..740ccb5 100644 --- a/sys/dev/fdt/fdt_common.c +++ b/sys/dev/fdt/fdt_common.c @@ -478,21 +478,31 @@ fdt_intr_decode(phandle_t intr_parent, pcell_t *intr, int *interrupt, int *trig, int *pol) { fdt_pic_decode_t intr_decode; + phandle_t intr_offset; int i, rv; + intr_offset = OF_xref_phandle(intr_parent); + for (i = 0; fdt_pic_table[i] != NULL; i++) { /* XXX check if pic_handle has interrupt-controller prop?
