hisilicon-ev200 / goke-gk7205v200: IMX307 high-fps presets

[widgetii]

Summary

Companion to OpenIPC/openhisilicon#104 (merged as 5b1aa42). Ships four IMX307 high-fps INI presets under /etc/sensors/high-fps/ for both V4 osdrv packages — hisilicon-osdrv-hi3516ev200 and goke-osdrv-gk7205v200 — mirroring the existing IMX335 high-fps preset layout.

Bumps HISILICON_OPENSDK_VERSION from 8b5e47f to 5b1aa42 to pull in the IMX307 Isp_SnsMode flex-mode dispatch added by openhisilicon#104.

Presets

Preset	Sensor mode	Selected by	Tested wire fps (h.265 @ 4 Mbps)
imx307_1920x1080_60fps.ini	1080p60 boost (FRSEL=1h auto-promotion)	Isp_FrameRate=60	44 fps — encoder-bound at 1080p; real benefit is latency (sensor readout 33→16.7 ms)
imx307_1280x720_60fps.ini	720p sub-readout (WINMODE=1h)	Isp_SnsMode=1	60 fps — sensor matches wire
imx307_640x480_130fps.ini	VGA flex window-crop (WINMODE=4h)	Isp_SnsMode=4 + Isp_W/Isp_H	130 fps — encoder ceiling
imx307_368x304_200fps.ini	smallest datasheet-allowed flex crop	Isp_SnsMode=4 + Isp_W/Isp_H	200 fps — encoder ceiling band 200-219

All four follow the existing IMX335 high-fps INI structure: minimal [sensor] / [mode] / [mipi] / [isp_image] / [vi_dev] sections, no vendor boilerplate.

Verified on real hardware

openipc-gk7205v200.dlab.doty.ru board, sony_imx307_2L driver loaded with openhisilicon master after #104. Wire fps measured from /proc/umap/venc SEND counter delta over a 5 s window after a 6 s warm-up. ISP IntRat confirms sensor delivers exactly the requested rate at each measurement; encoder is the wire-fps ceiling above sub-1080p modes.

ev200 (Hisilicon-side, same silicon family) expected to behave identically — not separately verified on the Hisi board (re-uses the shared sensor driver source). 4-lane variant (sony_imx307) not exposed by these presets (only sony_imx307_2L is shipped today); upstream driver carries the matching dispatch but is untested.

gk7205v200 specifics

The gk-side INIs carry the clock=37.125MHz override in [mode] — same as the IMX335 high-fps gk presets. Without it the gk vendor blob defaults to 27 MHz INCK and the delivered rate is ~73% of nominal.

Notable INI update

imx307_1280x720_60fps.ini on the gk-side is replaced (not merely modified). The prior file was a bloated stock-style INI with vendor boilerplate that never engaged the WINMODE=1h hardware path; majestic capped it at 45 fps via the V200 clamp and the sensor ran at 30 fps internally with VPSS downscale-from-1080p. The new file uses Isp_SnsMode=1 to dispatch to the dedicated 720p sub-readout path landed in openhisilicon#104.

Dependency on majestic

Requires majestic >= widgetii/majestic#77 (V200 chip_id 45 fps clamp removed, already merged on master). Without that, 1080p60 + any preset with Isp_FrameRate > 45 silently caps at 45 fps on V200 silicon — same gotcha as the existing IMX335 high-fps presets had before #77.

Test plan

• CI build green (firmware builds for hi3516ev200_lite, gk7205v200_lite, hi3516ev300_neo, gk7205v300_lite)
• Verified IMX307 720p60 / VGA130 / CIF200 / 1080p60 wire fps on gk7205v200 (sweep results in commit message)
• Smoke-test on ev200 dev board (same silicon, expected identical)
• Backwards-compat: existing stock IMX307 1080p30 path remains the default; users explicitly opt in to high-fps via cli -s .isp.sensorConfig /etc/sensors/high-fps/...
