Author: mav Date: Thu Aug 18 11:17:36 2016 New Revision: 304414 URL: https://svnweb.freebsd.org/changeset/base/304414 Log: MFC r302947: In AHCI_IRQ_MODE_AFTER mode do not clear interrupts below. This is probably a NOP change since IS register is not activery used for interrupts below the shared, but it looked odd to clear interrupts we did not handle.
