1Since 2.1.99-test5, pciutils should also be compilable on Windows. Thanks
2to Alexander Stock for contributing the port.

4Updated after version 2.2.6 to compile again, and with MinGW, even (only?)
5cross-compiling. (Hopefully it works with MSVC too.)

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