bw_validate

Name:Check whether MBA bandwidth percentage value is correct. The value is* checked against the minimum and maximum bandwidth values specified by* the hardware. The allocated bandwidth percentage is rounded to the next* control step available on the hardware.

Proto:static bool bw_validate_amd(char *buf, unsigned long *data, struct rdt_resource *r)

Type:bool

Parameter:

Type	Parameter	Name
char *	buf
unsigned long *	data
struct rdt_resource *	r

ret = kstrtoul - convert a string to an unsigned long*@s: The start of the string. The string must be null-terminated, and may also* include a single newline before its terminating null. The first character* may also be a plus sign, but not a minus sign.

If ret Then

rdt_last_cmd_printf("Non-decimal digit in MB value %s\n", buf)

Return false

If bw < min_bw || bw > default_ctrl Then

rdt_last_cmd_printf("MB value %ld out of range [%d,%d]\n", bw, min_bw, default_ctrl)

Return false

data = undup - round up to the next specified multiple*@x: the value to up*@y: multiple to round up to* Rounds @x up to next multiple of @y. If @y will always be a power* of 2, consider using the faster round_up().(bw, (unsignedlong)bw_gran)

Return true
