Use the generic pci_enable_resources() instead of the arch-specific code. Unlike this arch-specific code, the generic version: - checks PCI_NUM_RESOURCES (11), not 6, resources - skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set - skips ROM resources unless IORESOURCE_ROM_ENABLE is set - checks for resource collisions with "!r->parent", not IORESOURCE_UNSET Signed-off-by: NBjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Each architecture has its own pcibios_enable_resources() implementation. These differ in many minor ways that have nothing to do with actual architectural differences. Follow-on patches will make most arches use this generic version instead. This version is based on powerpc, which seemed most up-to-date. The only functional difference from the x86 version is that this uses "!r->parent" to check for resource collisions instead of "!r->start && r->end".

PCI Express ASPM defines a protocol for PCI Express components in the D0 state to reduce Link power by placing their Links into a low power state and instructing the other end of the Link to do likewise. This capability allows hardware-autonomous, dynamic Link power reduction beyond what is achievable by software-only controlled power management. However, The device should be configured by software appropriately. Enabling ASPM will save power, but will introduce device latency. This patch adds ASPM support in Linux. It introduces a global policy for ASPM, a sysfs file /sys/module/pcie_aspm/parameters/policy can control it. The interface can be used as a boot option too. Currently we have below setting: -default, BIOS default setting -powersave, highest power saving mode, enable all available ASPM state and clock power management -performance, highest performance, disable ASPM and clock power management By default, the 'default' policy is used currently. In my test, power difference between powersave mode and performance mode is about 1.3w in a system with 3 PCIE links. Note: some devices might not work well with aspm, either because chipset issue or device issue. The patch provide API (pci_disable_link_state), driver can disable ASPM for specific device.

The PCI bus names included in /proc/iomem and /proc/ioports are of the form 'PCI Bus #XX' where XX is the bus number. This patch changes the naming to 'PCI Bus XXXX:YY' where XXXX is the domain number and YY is the bus number. For example, PCI bus 14 in domain 0 will show as 'PCI Bus 0000:14' instead of 'PCI Bus #14'. This change makes the naming consistent with other architectures such as ia64 where multiple PCI domain support has been around longer.

This function was obviously never being used since early 2.5 days as any device that it would try to remove would never really be removed from the system due to the PCI device list being held in the driver core, not the general list of PCI devices. As we have not had a single report of a problem here in 4 years, I think it's safe to remove now. Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

由 Greg Kroah-Hartman 提交于
We currently keep 2 lists of PCI devices in the system, one in the driver core, and one all on its own. This second list is sorted at boot time, in "BIOS" order, to try to remain compatible with older kernels (2.2 and earlier days). There was also a "nosort" option to turn this sorting off, to remain compatible with even older kernel versions, but that just ends up being what we have been doing from 2.5 days... Unfortunately, the second list of devices is not really ever used to determine the probing order of PCI devices or drivers[1]. That is done using the driver core list instead. This change happened back in the early 2.5 days. Relying on BIOS ording for the binding of drivers to specific device names is problematic for many reasons, and userspace tools like udev exist to properly name devices in a persistant manner if that is needed, no reliance on the BIOS is needed. Matt Domsch and others at Dell noticed this back in 2006, and added a boot option to sort the PCI device lists (both of them) in a breadth-first manner to help remain compatible with the 2.4 order, if needed for any reason. This option is not going away, as some systems rely on them. This patch removes the sorting of the internal PCI device list in "BIOS" mode, as it's not needed at all anymore, and hasn't for many years. I've also removed the PCI flags for this from some other arches that for some reason defined them, but never used them. This should not change the ordering of any drivers or device probing. [1] The old-style pci_get_device and pci_find_device() still used this sorting order, but there are very few drivers that use these functions, as they are deprecated for use in this manner. If for some reason, a driver rely on the order and uses these functions, the breadth-first boot option will resolve any problem.

This cleans up the search.c file, now using the pci list of devices that are created for the driver core, instead of relying on our separate list of devices. It's better to use the functions already created for this kind of thing, instead of rolling our own all the time. This work is done in anticipation of getting rid of that second list of pci devices all together. And it ends up saving code, always a nice benefit. This also removes one compiler warning for when CONFIG_PCI_LEGACY is enabled as we no longer internally use the deprecated functions anymore. Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Add the security= boot parameter. This is done to avoid LSM registration clashes in case of more than one bult-in module. User can choose a security module to enable at boot. If no security= boot parameter is specified, only the first LSM asking for registration will be loaded. An invalid security module name will be treated as if no module has been chosen. LSM modules must check now if they are allowed to register by calling security_module_enable(ops) first. Modify SELinux and SMACK to do so. Do not let SMACK register smackfs if it was not chosen on boot. Smackfs assumes that smack hooks are registered and the initial task security setup (swapper->security) is done.

This patch effectively reverts commit d0498d9a aka "[NET]: Do not allocate unneeded memory for dev->priv alignment." It was found to be buggy because of final unconditional += NETDEV_ALIGN_CONST removal. For example, for sizeof(struct net_device) being 2048 bytes, "alloc_size" was also 2048 bytes, but allocator with debugging options turned on started giving out !32-byte aligned memory resulting in redzones overwrites. Patch does small optimization in ->priv'less case: bumping size to next 32-byte boundary was always done to ensure ->priv will also be aligned. But, no ->priv, no need to do that.
