[Qemu-devel] [PATCH v5 00/11] Add param Error ** for msi_init()

[Cao jin]

This patchset is for 2.7. This version has a huge change, so I hope to
get some comments first.

The change mostly is:
1. According suggestions, modify devices` msi/msix property type.
   its type mostly bit or uint, now change it to enum OnOffAuto,
   and default to "auto". So we will know if user want msi/msix or not,
   then the process will be:

                           /-> Fail: switch to the non-msi variant
     msi = auto -> msi_init
                           \-> Success: we got msi variant

                         /-> Fail: device creation fail
     msi = on -> msi_init
                         \-> Success: we got msi variant

2. For devices who don`t have msi/msix property, following its previous
   behaviour: if msi_init`s failure is non-fatal, then fall back to INTx
   silently, or else, device creation fail.

3. pci core: Assert ENOSPC error when add capability

4. fix to all the other tiny comments
