   1 Since 2.1.99-test5, pciutils should also be compilable on Windows. Thanks
   2 to Alexander Stock for contributing the port.
   3
   4 Updated after version 2.2.6 to compile again, and with MinGW, even (only?)
   5 cross-compiling. (Hopefully it works with MSVC too.)

   7 For simple listing PCI devices in system via win32-cfgmgr32 access method
   8 which provides only basic information and emulated config space, there is no
   9 special requirement. To list PCI resources on Windows 8 and higher versions,
  10 it is necessary to have architecture-native version (e.g. AMD64 version on
  11 AMD64 systems).
  12
  13 For config space access there are different windows specific access methods:
  14 - win32-kldbg - Kernel Local Debugging Driver kldbgdrv.sys
  15 - win32-sysdbg - NT SysDbg interface
  16 - intel-conf1 - Direct hardware access via Intel configuration mechanism 1
  17
  18 The default access method is win32-cfgmgr32 and by default it tries to use
  19 one of the above config access access method to provide as much as possible
  20 information to application. More details about particular access method and
  21 caveats are described in the pcilib(8) manual page.
  22
  23 To access config space via intel-conf1 access method on NT-based systems via
  24 NT ProcessUserModeIOPL system call, it is required to have SeTcbPrivilege
  25 (Act as part of the operating system privilege), which can be enabled in User
  26 Accounts settings (take effect after next login). By default this privilege is
  27 not enabled for any non-system user. Or alternatively it is required to be in
  28 local Administrators group and on Windows 2000 SP4 or higher systems to have
  29 SeImpersonatePrivilege (Impersonate a client after authentication privilege)
  30 which is by default enabled for all local Administrators accounts. There is no
  31 special requirement for DOS-based systems. 64-bit systems do not have to allow
  32 users to access config space even with SeTcbPrivilege.
  33
  34 To compile this port, run following command:
  35
  36   make CROSS_COMPILE=i586-mingw32msvc- HOST=i586-windows ZLIB=no IDSDIR=""
  37
  38 To build 64-bit version, run:
  39
  40   make CROSS_COMPILE=x86_64-w64-mingw32- HOST=x86_64-windows ZLIB=no IDSDIR=""
  41
  42 Sometimes compilation may fail due to broken or missing getopt implementation.
  43 In this case try to compile with additional make option: COMPAT_GETOPT=yes
  44
  45 Building of shared DLL library libpci3.dll is supported too but needs to be
  46 manually enabled by make option: SHARED=yes
  47
  48 This DLL library libpci3.dll has versioned symbols with stable ordinal numbers
  49 which provides backward and forward compatibility. Every symbol in DLL library
  50 has '@LIBPCI_3.<version>' suffix to achieve it. For linking application to
  51 libpci3.dll it is possible to generate import library from libpci3.def file.
  52 Such import library will provide import symbol names without versioned suffix
  53 as an alias for the latest symbol version, which matches function name in pci.h
  54 header file. The alias is resolved by the linker at linking time, so the final
  55 application binary would always reference only versioned symbol. DLL library
  56 libpci3.dll does not provide unversioned symbols, so for using GetProcAddress()
  57 or dlsym() it is needed to specify full versioned symbol name.
