| * ls-tree: Fix parsing devices on multidomain PCI systemPali Rohár2023-04-291-10/+49
| | | | | | | | | | | | | | | | | | | | | | Represent each domain as domain bridge under the &host_bridge and put root bus of each domain under the domain bridge. With this change lspci in tree view does not show zero bus on domain 0 in the output if this bus does not exist at all. Root bus in PCIe hierarchy does not have to be zero and on Freescale PowerPC systems it is common. Also with this change are separate domain showed in the output separately.

| * ls-tree: Do not read Primary Bus Number for PCI Bridges from PCI config spacePali Rohár2023-04-291-2/+1
| | | | | | | | | | | | | | | | | | | | For PCIe devices of PCI Bridge type is Primary Bus Number not used and the default value is 0. PCIe devices capture their Bus and Device numbers automatically from PCIe TLP packets. Instead of Primary Bus Number use Device Number because zero value confuse tree building algorithm. Existing code already expects that Device Number of PCI Bridge is already set to Primary Bus Number.

* Parameters: Keep the list sorted and remove duplicatesMartin Mares2023-03-051-4/+18
| | | | | | When multiple back-ends use the same option (e.g., "devmem.path"), they tend to define it each. This is not nice, but before we generalize these options properly, let us at least remove the duplicate definitions.
* libpci: Add PCIe ECAM access methodPali Rohár2023-03-057-5/+1166
| | | | | | | | | | This is a new direct hardware access method via PCIe ECAM (Enhanced Configuration Access Mechanism). It is available on all PCIe-compliant hardware. Requires root privileges and access to physical memory. ECAM mapping can be specified manually via a new ecam.addrs parameter or can be read from ACPI MCFG table. ACPI MCFG table can be located in the system or read from x86 BIOS memory.

| * libpci: win32-cfgmgr32: Add support for accessing config space via other backendPali Rohár2023-01-044-17/+140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend win32-cfgmgr32 backend and add a new option win32.cfgmethod for specifying other backend for accessing PCI config space. There are more config space access methods available on Windows and each is working only sometimes (either requires special privileges or special setup). So by default try to choose the first working one via order defined in pci probe_sequence[] array. If none is available then emulate PCI config space like before this change. Function pci_init_v35() is extended and renamed to pci_init_internal() to optionally do not throw errors and allow to specify one access method which will be skipped in AUTO mode. This is used to prevent choosing win32-cfgmgr32 as config space access method for win32-cfgmgr32.
* | Use "command -v" instead of "which"Martin Mares2023-03-041-5/+5
| | | | | | | | | | | | | | | | | | | | Apparently, people started considering "which" obsolete. I still consider "which" rather useful and definitely more comfortable to type than "command -v". Still, "command -v" should be more portable, so let us use it. I wonder which of the ancient systems which we are still supporting will be broken by this change...

| * | libpci: windows: Handle long paths generated by GetModuleFileName()Pali Rohár2022-11-181-1/+8
| | | | | | | | | | | | | | | | | | | | | C function fopen() implemented by msvcrt.dll requires special prefix "\\\\?\\" for paths longer than 260 bytes. Because GetModuleFileName() returns absolute path, it may be longer than 260 bytes. Add fixup to handle long paths.
| * | libpci: windows: Fix path returned by GetModuleFileName()Pali Rohár2022-11-181-3/+36
| | | | | | | | | | | | | | | GetModuleFileName() on Windows 10 has bugs and returns bogus path. Implement fixups to make path usable for later fopen() call.
| * | libpci: djgpp: Allow to specify empty IDSDIR=Pali Rohár2022-11-181-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | Like for windows builds this will cause to load pci.ids file from the same directory where is stored application binary. Code is same as for Windows, just djgpp uses global symbol __dos_argv0 instead of _pgmptr. Tested with following compile command: make CROSS_COMPILE=i586-pc-msdosdjgpp- HOST=i586-djgpp ZLIB=no DNS=no IDSDIR=
| * | libpci: windows: Fix locating path to pci.ids file for DLL buildsPali Rohár2022-11-181-1/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using shared libpci DLL library, it is expected that pci.ids file is stored in directory where is also libpci DLL library and not in directory where is application executable. Based on the build mode and compile options, choose the appropriate function for retrieving path to the libpci DLL library or application executable. Also pass correct module argument to GetModuleFileName() call.
| * | libpci: windows: Fix usage of GetModuleFileName()Pali Rohár2022-11-181-5/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Module file name can have arbitrary length despite all MS examples say about MAX_PATH upper limit. This limit does not apply for example when executable is running from network disk with very long UNC paths or when using "\\??\\" prefix for specifying executable binary path. So handle buffer truncatenation by retrying GetModuleFileName() call with larger buffer. Fixes loading of pci.ids file when lspci.exe binary is running from network drive with path longer than 260 bytes.

* libpci: mmio-ports: Add Extended PCIe Intel Type 1 access methodPali Rohár2022-11-185-17/+100
| | | | | | | Extended method allows to access all PCIe registers, including extended registers starting at 0x100 offset. This method uses 4 reserved buts above bus bits for PCIe registers. On ARM platforms it is very common for PCIe controllers. Like standard method, it needs to be properly configured.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Microsoft Kernel Local Debugging Driver (kldbgdrv.sys) allow access for userspace processes to the PCI config space. It supports access up to 65536 domains and whole 4096 bytes long extended PCIe config space. Driver is signed by Microsoft and is available for both 32-bit and 64-bit systems. Driver is not part of Windows system and has to be installed via WinDbg installation package. Standalone installers for WinDbg 6.12.2.633 version: 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 This kldbgdrv.sys API is used by the !pci command of new WinDbg kernel debugger for displaying PCI config space. API of this driver is available only for processes with Debug privilege and only if system was booted with Debugging option.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lot of non-x86 platforms also support Intel Type 1 mechanism. x86 IO ports CF8 and CFC are on these platforms mapped into standard memory space. Address mapping itself is platform or board specific and there is no default value. Lot of ARM boards with multiple PCIe controllers are multi-domain and each PCI domain has its own CF8/CFC (address/data) registers mapped into memory space. Add new mmio-conf1 backend which access CF8/CFC ports via MMIO and define new config option mmio-conf1.addrs which specify list of address/data register pairs in memory space for each PCI domain. Format of this option is: 0xaddr1/0xdata1,0xaddr2/0xdata2,...
