Function Documentation

riscv_debug_reg_to_s()

unsigned int riscv_debug_reg_to_s	(	char *	buf,
		enum riscv_debug_reg_ordinal	reg_ordinal,
		struct riscv_debug_reg_ctx	context,
		uint64_t	value,
		enum riscv_debug_reg_show	show
	)

This function is used to fill a buffer with a decoded string representation of register's value.

Parameters

buf	If non-NULL, the buffer to write the string into. Otherwise, the function does not perform any writes, it just calculates the number of characters used.
reg_ordinal	The ordinal of the register.
context	The structure, containing the information about the target, necessary to decode the register.
value	The value to be decoded.

Returns the number of characters used by the string representation (excluding '\0').

Example: const struct struct riscv_debug_reg_ctx context = { .abits = { .value = <abits value>, .is_set = true } }; char buf[riscv_debug_reg_to_s(NULL, DTM_DMI_ORDINAL, context, <dmi value>) + 1] riscv_debug_reg_to_s(buf, DTM_DMI_ORDINAL, context, <dmi value>);
