Binaries are picked by filling a ia_css_binary_descr +struct with various input and output parameters and then calling +ia_css_binary_find(). The shisp_240?0_v21.bin firmware file contains many +different binaries.
+ +The actual processing pipeline is made by loading one or more programs, +called binaries.
Photoframe v2 01 driver code#
The hmm code keeps a list of all allocations and when necessary +the hmm code finds the backing hmm-buffer-object (hmm_bo) by looking +up the hmm_bo based on the ISP virtual address. hmm_alloc() returns an ISP virtual +address. +The ISP has its own address-space and main memory needs to be mapped into +its address space through the ISP's MMU. It does not have its own memory, but instead uses main memory. + +The atomisp seems to be a generic DSP(ISP) like processor without a fixed +pipeline.
