9.1.10. The Rockchip Image Signal Processor Driver (rkisp1)¶
126.96.36.199. Versions and their differences¶
The rkisp1 block underwent some changes between SoC implementations. The vendor designates them as:
V10: used at least in rk3288 and rk3399
V11: declared in the original vendor code, but not used
V12: used at least in rk3326 and px30
V13: used at least in rk1808
V20: used in rk3568 and beyond
Right now the kernel supports rkisp1 implementations based on V10 and V12 variants. V11 does not seem to be actually used and V13 will need some more additions but isn’t researched yet, especially as it seems to be limited to the rk1808 which hasn’t reached much market spread.
V20 on the other hand will probably be used in future SoCs and has seen really big changes in the vendor kernel, so will need quite a bit of research.
188.8.131.52. Changes from V10 to V12¶
V12 supports a new CSI-host implementation but can still also use the same implementation from V10
The module for lens shading correction got changed from 12bit to 13bit width
The AWB and AEC modules got replaced to support finer grained data collection
184.108.40.206. Changes from V12 to V13¶
The list for V13 is incomplete and needs further investigation.
V13 does not support the old CSI-host implementation anymore
