From: Daniel Henrique Barboza
Subject: [Qemu-devel] [PATCH v15] migration: spapr: migrate pending_events of spapr state
Date: Tue, 11 Jul 2017 15:07:54 -0300

- changed default endianess of sPAPREventLogEntry to native
- write the header fields and the extended_log directly in the guest memory

- several changes made in spapr_events.c to allow for a minimal VMSD to be
migrated. Please check the commit message of the patch for more information.

This is the next version of the v13 that was sent a month ago. You can
check out the v13 discussions here:


Previous changes:

- rebased with dgibson/ppc-for-2.10
- patch 1 removed from the series (already applied at ppc-for-2.10)
- data_size is now being calculated by using the extended_length field inside

- patch 2: added a switch statement to get the proper data_size based on
the log_type

- patch 1 (new): cleanup of spapr_events.c:
    * removed the 'exception' boolean from the sPAPREventLogEntry
    * simplified the 'event_scan' function
- patch 2:
    * data_size is now calculated inside rtas_event_log_queue()
    * using VBUFFER instead of VARRAY to avoid casts
    * log_type changed to int32_t
