Since 2.1.99-test5, pciutils should also be compilable on Windows. Thanks
to Alexander Stock for contributing the port.
Updated after version 2.2.6 to compile again, and with MinGW, even (only?)
cross-compiling. (Hopefully it works with MSVC too.)
For simple listing PCI devices in system via win32-cfgmgr32 access method
which provides only basic information and emulated config space, there is no
special requirement. To list PCI resources on Windows 8 and higher versions,
it is necessary to have architecture-native version (e.g. AMD64 version on
AMD64 systems).
For config space access there are different windows specific access methods:
- win32-kldbg - Kernel Local Debugging Driver kldbgdrv.sys
- win32-sysdbg - NT SysDbg interface
- intel-conf1 - Direct hardware access via Intel configuration mechanism 1
The default access method is win32-cfgmgr32 and by default it tries to use
one of the above config access access method to provide as much as possible
information to application. More details about particular access method and
caveats are described in the pcilib(8) manual page.
The default access method for config space is win32-kldbg. It uses Microsoft's
Kernel Local Debugging Driver kldbgdrv.sys. This driver is not part of the
Windows system but is part of the Microsoft WinDbg tool. It is required to
have kldbgdrv.sys driver installed in the system32 directory or to have
windbg.exe or kd.exe binary in PATH. kldbgdrv.sys driver has some restrictions.
Process needs to have Debug privilege and Windows system has to be booted with
Debugging option. Debugging option can be enabled by calling (takes effect
after next boot): bcdedit /debug on
Download links for WinDbg 6.12.2.633 standalone installer from Microsoft:
https://download.microsoft.com/download/A/6/A/A6AC035D-DA3F-4F0C-ADA4-37C8E5D34E3D/setup/WinSDKDebuggingTools_amd64/dbg_amd64.msi
https://download.microsoft.com/download/A/6/A/A6AC035D-DA3F-4F0C-ADA4-37C8E5D34E3D/setup/WinSDKDebuggingTools/dbg_x86.msi
To access config space via intel-conf1 access method on NT-based systems via
NT ProcessUserModeIOPL system call, it is required to have SeTcbPrivilege
(Act as part of the operating system privilege), which can be enabled in User
Accounts settings (take effect after next login). By default this privilege is
not enabled for any non-system user. Or alternatively it is required to be in
local Administrators group and on Windows 2000 SP4 or higher systems to have
SeImpersonatePrivilege (Impersonate a client after authentication privilege)
which is by default enabled for all local Administrators accounts. There is no
special requirement for DOS-based systems. 64-bit systems do not have to allow
users to access config space even with SeTcbPrivilege.
To compile this port, run following command:
make CROSS_COMPILE=i586-mingw32msvc- HOST=i586-windows ZLIB=no IDSDIR=""
To build 64-bit version, run:
make CROSS_COMPILE=x86_64-w64-mingw32- HOST=x86_64-windows ZLIB=no IDSDIR=""
Sometimes compilation may fail due to broken or missing getopt implementation.
In this case try to compile with additional make option: COMPAT_GETOPT=yes
Building of shared DLL library libpci3.dll is supported too but needs to be
manually enabled by make option: SHARED=yes
This DLL library libpci3.dll has versioned symbols with stable ordinal numbers
which provides backward and forward compatibility. Every symbol in DLL library
has '@LIBPCI_3.<version>' suffix to achieve it. For linking application to
libpci3.dll it is possible to generate import library from libpci3.def file.
Such import library will provide import symbol names without versioned suffix
as an alias for the latest symbol version, which matches function name in pci.h
header file. The alias is resolved by the linker at linking time, so the final
application binary would always reference only versioned symbol. DLL library
libpci3.dll does not provide unversioned symbols, so for using GetProcAddress()
or dlsym() it is needed to specify full versioned symbol name.
