IMR (Isolated Memory Regions) is a mechanism to protect memory regions from unwarranted access by agents in the system that should not have access to that memory. When IMR is enabled, pages in the DRAM will be located within the IMR memory space, accessible only by the device. As a side effect, during S4 (a.k.a hibernate) the IMR memory space is not retained. While the DRAM is saved to the disk and restored by the OS upon resume, the IMR, which is hidden from the OS neither saved upon suspend nor restored upon resume. As a consequence of the above, it turned out that commands cannot be sent as part of the resume flow, and so after ending d3 the FW needs to use notifications instead of cmd-resp. The resume flow becomes asynchronous, with a series of notifications, starting with wowlan_info_notif, through wowlan_pkt_notif and complete the resume flow by d3_end_notif. This patch adds the support for wowlan info notification. The wake packet has been removed from the wowlan info struct and will be handled in a dedicated notification.
