78f4e2fe - powerpc64/powernv: re-read RTC after polling

Wed, 08 Aug 2018 21:19:07 +0000

powerpc64/powernv: re-read RTC after pollingIf OPAL_RTC_READ is busy and does not return the information on the first run,as returning OPAL_BUSY_EVENT, the system will crash since ymd and hmsm variablewill contain junk values.This is happening because we were not calling OPAL_RTC_READ again afterOPAL_POLL_EVENTS' return, which would finally replace the old/junk hmsm and ymdvalues.The code was also mixing OPAL_RTC_READ and OPAL_POLL_EVENTS return values.This patch fix this logic and guarantee that we call OPAL_RTC_READ afterOPAL_POLL_EVENTS return, and guarantee the code will only proceed ifOPAL_RTC_READ returns OPAL_SUCCESS.Reviewed by: jhibbitsApproved by: jhibbits (mentor)Differential Revision: https://reviews.freebsd.org/D16617 List of files: /freebsd-12.1/sys/powerpc/powernv/opal_dev.c
