[win-pv-devel] Parameterization vendor prefix and PCI device id

[Paul Durrant <Paul.Durrant@xxxxxxxxxx>]

Hi,

  My recent set of patches (one for each driver) to parameterize the device 
name vendor prefix and vendor PCI device id have a knock on effect on 
compatibility between drivers. This, however, is with good reason...

  There was a recent incident where Windows PV drivers were accidentally posted 
to Windows Update (not by Citrix) using binding names in use by Citrix 
XenServer. To avoid this sort of accident it seems prudent to parameterize the 
names and these patches do that.
  The default vendor prefix has been set to 'XP' (Xen Project) rather than 'XS' 
(XenServer). Citrix will continue to use the 'XS' prefix by setting it at build 
time, but for Xen Project development builds this means drivers built after 
these patches are applied will not be compatible with those before. The 
bindings for the XenServer vendor PCI device are also no longer hardcoded but 
this is unlikely to have an effect on most people unless they have been 
deliberately specifying this device in their VM config.
  I am also intending to back-port all the patches to the 8.1 branch and tag a 
new rc in the near future. I will mail out once the patches are there and the 
branches are tagged. With any luck I can also get rc builds posted to xenbits 
in the near future; that may require a little infrastructure tweaking though.

  Cheers,

    Paul
