cpudl_find

函数名称：pudl_find - find the best (later-dl) CPU in the system*@cp: the cpudl max-heap context*@p: the task*@later_mask: a mask to fill in with the selected CPUs (or NULL)* Returns: int - CPUs were found

函数原型：int cpudl_find(struct cpudl *cp, struct task_struct *p, struct cpumask *later_mask)

返回类型：int

参数：

类型	参数	名称
struct cpudl *	cp
struct task_struct *	p
struct cpumask *	later_mask

120

dl_se等于dl

122

如果later_mask且pumask_and - *dstp = *src1p & *src2p*@dstp: the cpumask result*@src1p: the first input*@src2p: the second input* If *@dstp is empty, returns 0, else returns 1则

124

返回:1

125

否则

126

best_cpu等于cpudl_maximum(cp)

128

WARN_ON(best_cpu != - 1 && !cpu_present(best_cpu))

130

如果测试CPU信息且dl_time_before( Absolute deadline for this instance , dl)则

132

如果later_mask则设置CPU信息

135

返回:1

138

返回:0
