函数名称:apbt_set_mapping
函数原型:static inline void apbt_set_mapping(void)
返回类型:void
参数:无
81 | phy_cs_timer_id等于0 |
83 | 如果apbt_virt_address则 |
84 | pr_debug("APBT base already mapped\n") |
85 | 返回 |
88 | 如果(mtmr == NULL)则 |
89 | printk(r conditions "Failed to get MTMR %d from SFI\n", APBT_CLOCKEVENT0_NUM) |
91 | 返回 |
94 | 如果非apbt_address则 |
95 | printk(warning conditions "No timer base from SFI, use default\n") |
99 | 如果非apbt_virt_address则 |
101 | pr_debug("Failed mapping APBT phy address at %lu\n", (unsignedlong)apbt_address) |
102 | 转到:panic_noapbt |
105 | sfi_free_mtmr(mtmr) |
109 | 如果(mtmr == NULL)则转到:panic_noapbt |
113 | pr_debug("Use timer %d for clocksource\n", (int)( phy base addr for the timer & 0xff) / APBTMRS_REG_SIZE) |
115 | phy_cs_timer_id等于 phy base addr for the timer 按位与0xff的值除APBTMRS_REG_SIZE |
118 | clocksource_apbt等于dw_apb_clocksource_init(APBT_CLOCKSOURCE_RATING, "apbt0", apbt_virt_address + phy_cs_timer_id * APBTMRS_REG_SIZE, Common DW APB timer info) |
121 | 返回 |
123 | panic_noapbt : |
名称 | 描述 |
---|---|
apbt_time_init | Early setup the APBT timer, only use timer 0 for booting then switch to* per CPU timer if possible.* returns 1 if per cpu apbt is setup* returns 0 if no per cpu apbt is chosen* panic if set up failed, this is the only platform timer on Moorestown. |
apbt_quick_calibrate | alled before apb_timer_enable, use early map |
