This commit mainly targets the ESP32-P4. It adds supports for coprocessors on RISC-V based targets. The coprocessor save area, describing the used coprocessors is stored at the end of the stack of each task (highest address) whereas each coprocessor save area is allocated at the beginning of the task (lowest address). The context of each coprocessor is saved lazily, by the task that want to use it.
soc
The soc component provides hardware description for targets supported by ESP-IDF.
- `xxx_reg.h` - defines registers related to the hardware
- `xxx_struct.h` - hardware description in C `struct`
- `xxx_channel.h` - definitions for hardware with multiple channels
- `xxx_caps.h` - features/capabilities of the hardware
- `xxx_pins.h` - pin definitions
- `xxx_periph.h/*.c` - includes all headers related to a peripheral; declaration and definition of IO mapping for that hardware
