From 7a72c705acc23db85ae5fdff250fe42567029476 Mon Sep 17 00:00:00 2001 From: Lubomir Rintel Date: Mon, 2 Sep 2019 17:11:05 +0200 Subject: initrd: add devicetree support This adds capability to hand over the network configuration from OpenFirmware (and potentially other boot loaders with openfirmware support such as U-Boot) to NetworkManager. It's done analogously to ACPI/iBFT. In fact, the same ip=ibft command line option is used, adding a more general ip=fw alias. This probably deserves some documentation, but I'm not adding any at this time. https://gitlab.freedesktop.org/NetworkManager/NetworkManager/merge_requests/257 --- src/devices/wwan/tests/test-service-providers | Bin 0 -> 10070856 bytes src/initrd/meson.build | 1 + src/initrd/nm-initrd-generator.h | 2 + src/initrd/nmi-cmdline-reader.c | 10 +- src/initrd/nmi-dt-reader.c | 411 +++++++++++++++++++++ src/initrd/tests/meson.build | 1 + .../firmware/devicetree/base/chosen/bootpath | Bin 0 -> 108 bytes .../firmware/devicetree/base/chosen/bootp-request | Bin 0 -> 273 bytes .../firmware/devicetree/base/chosen/bootp-response | Bin 0 -> 300 bytes .../firmware/devicetree/base/chosen/bootpath | Bin 0 -> 37 bytes .../firmware/devicetree/base/chosen/broadcast-ip | 1 + .../firmware/devicetree/base/chosen/client-ip | 2 + .../firmware/devicetree/base/chosen/client-name | Bin 0 -> 9 bytes .../firmware/devicetree/base/chosen/domain-name | Bin 0 -> 15 bytes .../firmware/devicetree/base/chosen/gateway-ip | 2 + .../sysfs-dt/firmware/devicetree/base/chosen/name | Bin 0 -> 7 bytes .../firmware/devicetree/base/chosen/netmask-ip | Bin 0 -> 4 bytes .../firmware/devicetree/base/chosen/root-path | Bin 0 -> 1 bytes .../firmware/devicetree/base/chosen/server-ip | 2 + .../firmware/devicetree/base/chosen/tftp-file | Bin 0 -> 11 bytes .../firmware/devicetree/base/chosen/vendor-options | Bin 0 -> 1 bytes .../firmware/devicetree/base/ethernet/device_type | Bin 0 -> 8 bytes .../devicetree/base/ethernet/local-mac-address | 1 + .../firmware/devicetree/base/ethernet/mac-address | 1 + .../firmware/devicetree/base/ethernet/name | Bin 0 -> 9 bytes src/initrd/tests/test-dt-reader.c | 147 ++++++++ 26 files changed, 580 insertions(+), 1 deletion(-) create mode 100755 src/devices/wwan/tests/test-service-providers create mode 100644 src/initrd/nmi-dt-reader.c create mode 100644 src/initrd/tests/sysfs-dt-tftp/firmware/devicetree/base/chosen/bootpath create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/bootp-request create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/bootp-response create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/bootpath create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/broadcast-ip create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/client-ip create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/client-name create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/domain-name create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/gateway-ip create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/name create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/netmask-ip create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/root-path create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/server-ip create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/tftp-file create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/chosen/vendor-options create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/ethernet/device_type create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/ethernet/local-mac-address create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/ethernet/mac-address create mode 100644 src/initrd/tests/sysfs-dt/firmware/devicetree/base/ethernet/name create mode 100644 src/initrd/tests/test-dt-reader.c (limited to 'src') diff --git a/src/devices/wwan/tests/test-service-providers b/src/devices/wwan/tests/test-service-providers new file mode 100755 index 0000000000..26c1bf2a66 Binary files /dev/null and b/src/devices/wwan/tests/test-service-providers differ diff --git a/src/initrd/meson.build b/src/initrd/meson.build index fa8c016b8d..acef8c4eac 100644 --- a/src/initrd/meson.build +++ b/src/initrd/meson.build @@ -1,5 +1,6 @@ sources = files( 'nmi-cmdline-reader.c', + 'nmi-dt-reader.c', 'nmi-ibft-reader.c', ) diff --git a/src/initrd/nm-initrd-generator.h b/src/initrd/nm-initrd-generator.h index dab6fb640d..579dfb34d4 100644 --- a/src/initrd/nm-initrd-generator.h +++ b/src/initrd/nm-initrd-generator.h @@ -41,6 +41,8 @@ GHashTable *nmi_ibft_read (const char *sysfs_dir);
