2022-04-03Obtain correct value of is_64 and is_prefetchable PCI device fieldsChester Gillon
Correct setting of the is_64 and is_prefetchable pci_device fields in pci_device_linux_sysfs_probe(). The pci_device struct defines is_64 and is_prefetchable as single bits, but the previous code was attempting to store the result of a bit-masked field in a single bit which always resulted in is_64 and is_prefetchable being zero regardless of the actual capabilities of the PCI device.

3e0d1cde0187 ("hurd: Implement device memory mapping") was making root-running processes insist on using the pci device, and never try the fs-provided translator. This reverts back to trying the pci device first, but completely, and then revert to the fs-provided translator.

2019-07-10freebsd_pci: Make this work on sparc64Niclas Zeising
Make the FreeBSD libpciaccess routines work on FreeBSD. The FreeBSD sparc64 architecture needs special treatment, similar to the PCI_MAGIC_IO_RANGE code. However, PCI_MAGIC_IO_RANGE has been gone for some time. Give this a chance to work on sparc64 anyway. This code has been in the FreeBSD ports tree for some time.
2019-07-10freebsd_pci: update legacy I/O for new architecturesNiclas Zeising
Update FreeBSD legacy I/O routines for new architectures. When we're not on amd64 or i386, and PCI_MAGIC_IO_RANGE is not defined, use IOCTLs to handle reads and writes through /dev/io. This is accomplished by opening /dev/io and using IOCTLs from dev/io/iodev.h, an interface that exists on most FreeBSD architectures. This change has been in the FreeBSD ports tree for quite some time.

2018-10-24linux: Set number of devices to 0 in case of errorOlivier Fourdan
pci_sys is a global variable which is populated on init, and in case of error reading sysfs on Linux, the devices are NULL, but the number of devices is left unchanged. As a result, we may crash in `pci_device_next()` which relies on the number of devices. To fix the issue, simply reset the number of devices to zero in case of error so we don't try to access indices of a NULL array later on. Signed-off-by: Olivier Fourdan <ofourdan@redhat.com>

2017-09-20linux: support 32 bit PCI domains (v3)Stephen Hemminger
The PCI domain may be larger than 16 bits on Microsoft Azure and other virtual environments. PCI busses reported by ACPI are limited to 16 bits, but in Azure the domain value for pass through devices is intentionally larger than 16 bits to avoid clashing with local devices. This is needed to support pass through of GPU devices. v3: (ajax) Update FreeBSD and Solaris backends to preserve the full 32-bit domain number, since on those OSes it stands a chance of working already. Update NetBSD and OpenBSD backends to initialize domain_16 compatibly with older libpciaccess; neither backend appears to support more than a handful of domains to begin with though. Trivially update the generic x86 backend for source compatibility, though it still only supports one domain and will never be better.

2017-04-04configure.ac: set AC_CONFIG_AUX_DIREmil Velikov
If not set, libtool will search directories up to ../.. for an install-sh and then dump the aux files there. This caused a couple of problems with the xorg release.sh script that now uses worktrees but is generally bad behaviour because we can't guarantee that we're not inside some other repository. Set AC_CONFIG_AUX_DIR to avoid this behavior. See https://lists.freedesktop.org/archives/xorg-devel/2017-March/053006.html Note: the commit and above message are shamelessly copied from libinput.

It is used to guide people who incorrectly set configure --srcdir. To be actually useful the macro should point to a rather unique file - which in our current case is a false premise.
