      sPAPR: Implement EEH RTAS calls · ee954280
      由 Gavin Shan 提交于 
      The emulation for EEH RTAS requests from guest isn't covered
by QEMU yet and the patch implements them.

The patch defines constants used by EEH RTAS calls and adds
callbacks sPAPRPHBClass::{eeh_set_option, eeh_get_state, eeh_reset,
eeh_configure}, which are going to be used as follows:

  * RTAS calls are received in spapr_pci.c, sanity check is done
    there.
  * RTAS handlers handle what they can. If there is something it
    cannot handle and the corresponding sPAPRPHBClass callback is
    defined, it is called.
  * Those callbacks are only implemented for VFIO now. They do ioctl()
    to the IOMMU container fd to complete the calls. Error codes from
    that ioctl() are transferred back to the guest.

      spapr_vio: Convert to realize() · 28b07e73
      由 Markus Armbruster 提交于 
      Bonus fix: always set an error on failure.  Some failures were silent
before, except for the generic error set by device_realize().

      pseries: Switch VGA endian on H_SET_MODE · eefaccc0
      由 David Gibson 提交于 
      When the guest switches the interrupt endian mode, which essentially
means a global machine endian switch, we want to change the VGA
framebuffer endian mode as well in order to be backward compatible
with existing guests who don't know about the new endian control
register.

      pseries: Move rtc_offset into RTC device's state structure · 880ae7de
      由 David Gibson 提交于 
      The initial creation of the PAPR RTC qdev class left a wart - the rtc's
offset was left in the sPAPREnvironment structure, accessed via a global.

This patch moves it into the RTC device's own state structure, were it
belongs.  This requires a small change to the migration stream format.  In
order to handle incoming streams from older versions, we also need to
retain the rtc_offset field in the sPAPREnvironment structure, so that it
can be loaded into via the vmsd, then pushed into the RTC device.

Since we're changing the migration format, this also takes the opportunity
to:

  * Change the rtc offset from a value in seconds to a value in
    nanoseconds, allowing nanosecond offsets between host and guest
    rtc time, if desired.

  * Remove both the already unused "next_irq" field and now unused
    "rtc_offset" field from the new version of the spapr migration
    stream

      pseries: Make the PAPR RTC a qdev device · 28df36a1
      由 David Gibson 提交于 
      At present the PAPR RTC isn't a "device" as such - it's accessed only via
firmware/hypervisor calls, and is handled in the sPAPR core code.  This
becomes inconvenient as we extend it in various ways.

This patch makes the PAPR RTC a separate device in the qemu device model.

For now, the only piece of device state - the rtc_offset - is still kept in
the global sPAPREnvironment structure.  That's clearly wrong, but leaving
it to be fixed in a following patch makes for a clearer separation between
the internal re-organization of the device, and the behavioural changes
(because the migration stream format needs to change slightly when the
offset is moved into the device's own state).
