149 | /* The lower level RTC driver may return -1 in some fields, | ||
150 | * creating invalid alarm->time values, for reasons like: | ||
151 | * | ||
152 | * - The hardware may not be capable of filling them in; | ||
153 | * many alarms match only on time-of-day fields, not | ||
154 | * day/month/year calendar data. | ||
155 | * | ||
156 | * - Some hardware uses illegal values as "wildcard" match | ||
157 | * values, which non-Linux firmware (like a BIOS) may try | ||
158 | * to set up as e.g. "alarm 15 minutes after each hour". | ||
159 | * Linux uses only oneshot alarms. | ||
160 | * | ||
161 | * When we see that here, we deal with it by using values from | ||
162 | * a current RTC timestamp for any missing (-1) values. The | ||
163 | * RTC driver prevents "periodic alarm" modes. | ||
164 | * | ||
165 | * But this can be racey, because some fields of the RTC timestamp | ||
166 | * may have wrapped in the interval since we read the RTC alarm, | ||
167 | * which would lead to us inserting inconsistent values in place | ||
168 | * of the -1 fields. | ||
169 | * | ||
170 | * Reading the alarm and timestamp in the reverse sequence | ||
171 | * would have the same race condition, and not solve the issue. | ||
172 | * | ||
173 | * So, we must first read the RTC timestamp, | ||
174 | * then read the RTC alarm value, | ||
175 | * and then read a second RTC timestamp. | ||
176 | * | ||
177 | * If any fields of the second timestamp have changed | ||
178 | * when compared with the first timestamp, then we know | ||
179 | * our timestamp may be inconsistent with that used by | ||
180 | * the low-level rtc_read_alarm_internal() function. | ||
181 | * | ||
182 | * So, when the two timestamps disagree, we just loop and do | ||
183 | * the process again to get a fully consistent set of values. | ||
184 | * | ||
185 | * This could all instead be done in the lower level driver, | ||
186 | * but since more than one lower level RTC implementation needs it, | ||
187 | * then it's probably best best to do it here instead of there.. | ||
