2024-06-05util/hexdump: Inline g_string_append_printf "%02x"Richard Henderson1-1/+11
Trivial arithmetic can be used for emitting the nibbles, rather than full-blown printf formatting. Signed-off-by: Richard Henderson <richard.henderson@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Message-Id: <20240412073346.458116-6-richard.henderson@linaro.org>
2024-06-05util/hexdump: Add unit_len and block_len to qemu_hexdump_lineRichard Henderson1-9/+21
Generalize the current 1 byte unit and 4 byte blocking within the output. Signed-off-by: Richard Henderson <richard.henderson@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Message-Id: <20240412073346.458116-5-richard.henderson@linaro.org>
2024-06-05util/hexdump: Use a GString for qemu_hexdump_lineRichard Henderson1-11/+16
Allocate a new, or append to an existing GString instead of using a fixed sized buffer. Require the caller to determine the length of the line -- do not bound len here. Signed-off-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20240412073346.458116-4-richard.henderson@linaro.org>
2024-06-04util/hexdump: Remove ascii parameter from qemu_hexdump_lineRichard Henderson1-22/+30
Split out asciidump_line as a separate function, local to hexdump.c, for use by qemu_hexdump. Use "%-*s" to generate the alignment between the hex and the ascii, rather than explicit spaces.

2024-06-04util/hexdump: Remove b parameter from qemu_hexdump_lineRichard Henderson1-7/+6
Require that the caller output the offset and increment bufptr. Use QEMU_HEXDUMP_LINE_BYTES in vhost_vdpa_dump_config instead of raw integer.

2020-09-11util/hexdump: Reorder qemu_hexdump() argumentsPhilippe Mathieu-Daudé1-2/+2
qemu_hexdump()'s pointer to the buffer and length of the buffer are closely related arguments but are widely separated in the argument list order (also, the format of <stdio.h> function prototypes is usually to have the FILE* argument coming first). Reorder the arguments as "fp, prefix, buf, size" which is more logical.

2020-09-11util/hexdump: Convert to take a void pointer argumentPhilippe Mathieu-Daudé1-1/+3
Most uses of qemu_hexdump() do not take an array of char as input, forcing use of cast. Since we can use this helper to dump any kind of buffer, use a pointer to void argument instead.

2016-04-06util: Improved qemu_hexmap() to include an ascii dump of the bufferIsaac Lozano1-11/+22
qemu_hexdump() in util/hexdump.c has been changed to give also include a ascii dump of the buffer. Also, calls to hex_dump() in net/net.c have been replaced with calls to qemu_hexdump(). This takes care of two misc BiteSized Tasks.
