2019-07-12x86: Use MAP_SHARED for memory/rom region mmap && fix modeDamien Zammit

It no longer exists in newer glibc, and didn't work like you'd have hoped on anything but strongarm anyway.

2019-07-11New module for the HurdDamien Zammit
This new module uses Hurd's RPCs for accessing the PCI configuration space. Direct access as in {read_write}_{8,16,32} functions is done by the old x86 module. Some x86 function prototypes are now declared in a new header for the Hurd module to use them, in order to duplicate as little code as possible.

2019-07-10freebsd_pci: remove old probe methodNiclas Zeising
Remove the old probe method. The PCIOCGETBAR ioctl has been in FreeBSD since 8.0 release, if not earlier. Remove the old way of doing it. This is done using unifdef -DPCIOCGETBAR and cleaning up whitespace. Signed-off-by: Niclas Zeising <zeising@daemonic.se>
2019-07-10freebsd_pci: format freebsd_pci_methodsNiclas Zeising
Format freebsd_pci_methods a bit, adding some whitespace and assigning NULL to methods not implemented. This makes it easier to see the names of various methods, as well as which methods are not implemented. Idea from src/linux_sysfs.c Signed-off-by: Niclas Zeising <zeising@daemonic.se>
2019-07-10freebsd_pci: Add has_kernel_driver functionNiclas Zeising
Add a has_kernel_driver function to the FreeBSD libpciaccess functions. This uses the PCIOCATTACHED ioctl to check if a driver is attached to a specific PCI device. Idea taken from the FreeBSD system utility pciconf. Signed-off-by: Niclas Zeising <zeising@daemonic.se>

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.

2019-07-10Don't check for struct pci_io.pi_sel.pc_domainNiclas Zeising
Autoconf has a check that pci_io.pi_sel.pc_domain exists. This is only used on FreeBSD. pc_domain was added to pci_io.pi_sel on FreeBSD many many releases ago, and exists on all current FreeBSD releases. Remove the check, and the corresponding HAVE_PCI_IO_PC_DOMAIN, and update the code to take into account that #ifdef HAVE_PCI_IO_PC_DOMAIN is now always true.

2019-07-10freebsd_pci: Try to conform to uniform styleNiclas Zeising
Try to make freebsd_pci.c conform to a more uniform style. This change is whitespace only, no functional change intended. Signed-off-by: Niclas Zeising <zeising@daemonic.se>
2019-06-16freebsd: Add !legacy open_device_io implementationConrad Meyer
Some drivers, such as QXL, rely on this method and do not check for errors when it is unavailable. FreeBSD's legacy method can enumerate any d/b/s/f just fine, so it should be adequate for the !legacy API, as far as I can tell. With this change, QXL doesn't crash on startup on FreeBSD. Signed-off-by: Conrad Meyer <cem@FreeBSD.org>
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.

2017-01-11linux sysfs: retrieve vendor, device... info via separate sysfs filesEmil Velikov
Currently the kernel does not expose the revision file. With that about to change (due in 4.10) we can read all the information required from separate files and avoid opening the config one. The latter has the [negative] side effect of waking up the device, which in some cases can be quite costly.

2016-08-15Ignore 32-bit domainsKeith Busch
A pci "domain" need not be limited to the 16-bits. The Linux kernel currently supports 32-bit domains which cause startx to segfault. Updating libpciaccess to support 32-bit domains breaks the library's ABI, and domains requiring 32-bits are not necessary for startx anyway, so this patch ignores them.
