30e9f21e - Get rid of workarounds for Linux systems without pread/pwrite

Fri, 29 Dec 2023 14:23:00 +0000

Get rid of workarounds for Linux systems without pread/pwriteMany things have changed since we introduced work-arounds for Linuxsystems with missing pread/pwrite in 1999 (if you are curious, it wasin commit bc6346df8d89ece4814be7dff951ec1a7d259938).I believe that it is supported by all reasonably recent Linux systemsnow. After all, pread() was already defined by POSIX.1-2001.This should also fix problems with musl libc mentioned in GitHubissue #158. List of files: /pciutils/lib/Makefile

2ba0f6f4 - libpci: Add PCIe ECAM access method

Sun, 29 Jan 2023 23:39:36 +0000

libpci: Add PCIe ECAM access methodThis is a new direct hardware access method via PCIe ECAM (EnhancedConfiguration Access Mechanism). It is available on all PCIe-complianthardware. Requires root privileges and access to physical memory.ECAM mapping can be specified manually via a new ecam.addrs parameter orcan be read from ACPI MCFG table. ACPI MCFG table can be located in thesystem or read from x86 BIOS memory. List of files: /pciutils/lib/Makefile

0a7350fb - libpci: Add Intel Type 1 implementation for memory mapped systems

Sun, 02 Jan 2022 19:50:41 +0000

libpci: Add Intel Type 1 implementation for memory mapped systemsLot of non-x86 platforms also support Intel Type 1 mechanism. x86 IO portsCF8 and CFC are on these platforms mapped into standard memory space.Address mapping itself is platform or board specific and there is nodefault value.Lot of ARM boards with multiple PCIe controllers are multi-domain and eachPCI domain has its own CF8/CFC (address/data) registers mapped into memoryspace.Add new mmio-conf1 backend which access CF8/CFC ports via MMIO and definenew config option mmio-conf1.addrs which specify list of address/dataregister pairs in memory space for each PCI domain. Format of this optionis: 0xaddr1/0xdata1,0xaddr2/0xdata2,... List of files: /pciutils/lib/Makefile

Sun, 08 May 2022 12:31:11 +0000

libpci: Put name and version information into DLL libraryGenerate rc file from in template and fill DLL name and DLL version fromMakefile.It looks like that the only possible way via GNU tools to specify versioninformation for DLL library is via text rc file compiled as COFF objectfile via GNU windres and linked into the final DLL library via GNU ld.

32934d5b - libpci: Add support for building versioned shared Windows DLL library libpci3.dll

Sun, 08 May 2022 08:25:59 +0000

libpci: Add support for building versioned shared Windows DLL library libpci3.dllPE/COFF format, used by DLL libraries, does not support version symbolslike ELF format. Recommendation from Microsoft for DLL symbol versioning isto use DLL API sets. But DLL API sets scheme requires for every API changeto generated a new slim forwarding DLL library, which is unsuitable fordistribution which wants just one DLL library with all version symbols.So instead of Microsoft recommended scheme for DLL versioning, use newdifferent versioning scheme: Symbol is composed by function name, at (@)character and version string (version is same as for ELF targets). Symbolname without version information is added only into the DLL DEF file asalias to symbol with higest version. So linker at application link timeresolves "unversioned" symbol to the versioned one via this alias and puts"versioned" symbol into final executable. This works fine if GNU LD islinking application via import library libpci3.dll.a generated from thatDLL DEF file libpci3.def. But does not work when linking directly to theDLL library because library itself does not contain aliases. Note that GNULD does not support linking to DEF file (it is required to first generatedimport library from DEF file).Note that older GNU LD versions have bug which cause generation ofcorrupted DLL files if some symbol contains dot (.) character. Hopefullythis bug was fixed in GNU LD 2.21.At the end application lspci.exe requires library libpci3.dll with symbolspci_alloc@LIBPCI_3.0, pci_init@LIBPCI_3.5, pci_fill_info@LIBPCI_3.8 andtherefore libpci3.dll stays backward compatible with future changes.PE/COFF executables can reference symbols either via name or via itsordinal number. Because DLL DEF files are generated from libpci versionscript and generator ver2def.pl preserves order of symbols, it means thatordinal numbers stay backward compatible unless order of lines in versionscript is changed.WARNINGS:GCC an GNU LD for Windows target have some bugs which cause that-fvisibility=hidden switch and __attribute__((visibility("default"))) doesnot work. Seems that they are broken and ignored when building DLL library.So instead use -Wl,--exclude-all-symbols switch with explicit DLL DEF filefor building DLL library, which seems to work. This switch is supportedsince GNU LD 2.21.GNU LD has also another bug which results in broken DLL library if inputDLL DEF file which describes symbols for exports, contains also symbolaliases via == operator.So do not specify symbol aliases in input DLL DEF file for building DLLlibrary. Instead construct separate DLL DEF file for building libpci3.dllwithout symbol aliases and separate DLL DEF file libpci3.def with symbolaliases for building import library libpci3.dll.a suitable for linking intotarget applications. Note that operator == for symbol aliases is supportedsince GNU dlltool 2.21.Generate those two DLL DEF files via new script ver2def.pl from libpci.verversion script. So exported functions and version symbols would be definedonly at one place in file libpci.ver.Note that GNU LD for Windows targets has also broken support for versionscripts, it exports nonsense data and completely ignores versioninformation. So always use only DLL DEF files generated by ver2def.plscript and never pass original version script to GNU LD.Due to another bugs in GNU dlltool, ordinals for aliased symbols from DLLDEF file are calculated incorrectly when building import library. Socalculate ordinals manually in ver2def.pl script and explicitly put theninto generated libpci3.def DLL DEF file for every symbol, includingaliases.And because aliases are stored only in libpci3.def file (and in importlibrary libpci3.dll.a generated from that DEF file) and not in DLL librarylibpci3.dll itself, it is required to link all libpci applications viaimport library and not directly to libpci3.dll. This is limitation ofPE/COFF format used by DLL libraries.So for building Windows DLL library libpci3.dll is needed to use GNUbinutils 2.21 or new. List of files: /pciutils/lib/Makefile

2d0af6fc - libpci: Add new windows NT sysdbg implementation

Sun, 02 Jan 2022 19:51:02 +0000

libpci: Add new windows NT sysdbg implementationNT SysDbg interface allow access to the PCI config space. Only devices onthe first domain are available and only first 256 bytes of the PCI configspace can be accessed. Compared to intel-conf1 access, this API is racefree as NT kernel serialize access to PCI I/O ports. This NT SysDbg API isused by the !pci command of 32-bit WinDbg kernel debugger for displayingPCI config space. Debug privilege is required to use this NT interface.
