hisilicon-opensdk: wire up hi3519v101 open_ modules into firmware - #2010
Merged
Conversation
Add V3A (hi3519v101) support — same pattern as CV500. hi3519v101 has OSAL (source-compiled), so blobs call osal_* wrappers and no code fixes were needed in openhisilicon. Key details: - Kernel 3.18.20 (module path /lib/modules/3.18.20/hisilicon/) - Blob prefix: hi3519v101_*, source prefix: hi_* - 38 modules installed with vendor-compatible names - Image fits lite flash (5048KB < 5120KB) Also enables opensdk for hi3516av200 (same SOC_FAMILY=hi3519v101).

In per-package mode, target-finalize merges per-package/*/target/ into
output/target/ via $(call per-package-rsync,$(sort $(PACKAGES)),...).
The $(sort ...) is alphabetical, so hisilicon-osdrv-* always rsyncs
after hisilicon-opensdk and clobbers any file we install at the same
path -- even though HISILICON_OPENSDK_DEPENDENCIES sequences us after
osdrv during build.
Net effect: every file opensdk and osdrv share a path for ends up as
the osdrv vendor blob in the shipped image. Verified on a hi3516av200
(hi3519v101 SDK) test camera:
- /usr/lib/sensors/libsns_imx385.so -- vendor blob (stSnsObj),
not opensdk's source-built lib (stSnsImx385Obj). Majestic fails:
sensor_getsnsobj@101 Cannot load symbol 'stSnsImx385Obj' from driver
Cannot init sensor / Cannot start SDK
- /lib/modules/3.18.20/hisilicon/hi_mipi.ko -- vendor blob,
not opensdk's open_mipi_rx.ko (so PR #2010's open kernel modules
have been silently inactive on hi3519v101 since it landed).
Same trap exists for hi3516cv500 (imx335/307/415 + ~30 .ko files)
and hi3516ev200 (imx307).
Fix: register a TARGET_FINALIZE_HOOK that re-rsyncs opensdk's
per-package target tree onto output/target/ after buildroot's
alphabetical merge runs. Opensdk's per-package staging is already
"osdrv contents + opensdk overlay" (because of the existing
_DEPENDENCIES), so a plain rsync -a is exactly what we want
to apply on top.
Gated on BR2_PER_PACKAGE_DIRECTORIES=y; without per-package mode
install ordering already does the right thing.
Verified post-fix on the same camera: source-built libsns_imx385.so
loads, sensor inits ("-------Sony IMX385 Sensor 1080p30 Initial OK!-------"),
RTSP starts, /image.jpg returns a valid 1920x1080 JPEG.

Summary
Add V3A (hi3519v101) support — fifth platform after CV200, CV100, AV100, CV500.
hi3519v101 has OSAL (source-compiled) like CV500, so blobs call
osal_*wrappers. Zero code fixes needed in openhisilicon — only firmware wiring./lib/modules/3.18.20/hisilicon/hi3519v101_*, source prefix:hi_*Test plan
