[Xen-devel] [PATCH v10 0/5] iommu: add rmrr Xen command line option

[elena.ufimtseva@xxxxxxxxxx]

From: Elena Ufimtseva <elena.ufimtseva@xxxxxxxxxx>

Add Xen command line option rmrr to specify RMRR                                
regions for devices that are not defined in ACPI thus                           
causing IO Page Fault while booting dom0 in PVH mode.                           
These additional regions will be added to the list of                           
RMRR regions parsed from ACPI.                                                  

Changes in v10:
 - incorporate patch 'dmar: device scope mem leak fix' as series requires it.
 - move patch 'pci: add PCI_SBDF and PCI_SEG macros' close to the last patch 
which uses it;
 
Changes in v9:                                                                  
- skip to next RMRR region if current overlaps with any in acpi_rmrr_units;    
- fix typos in commit messages;                                                
 - remove clean up chages introduced by mistake in v8;                          
                                                                                
Changes in v8:                                                                  
 - removed bogus debug in patch 1 with non-functional changes;                  
 - changed PRI_RMRRL macro for formatting to reflect the fact that two arguments
   are used, so make it PRI_RMRR(s,e) for formatting inclusive RMRR range;      
   'L' is also removed from macro name, which meant to server as a type of 
arguments (%lx);
 - added overlapping check with RMRRs from ACPI;                                
 - added check based on paddr_bits for pfn's in extra RMRR range (not sure if   
   its redundant with mfn_valid);                                               
 - addressed while loop exit condition in extra RMRRs parser;                   
                                                            
Elena Ufimtseva (5):
  dmar: device scope mem leak fix
  iommu VT-d: separate rmrr addition function
  pci: add wrapper for parse_pci
  pci: add PCI_SBDF and PCI_SEG macros
  iommu: add rmrr Xen command line option for extra rmrrs
