* PCI: add generic pci_enable_resources()Bjorn Helgaas2008-04-21
| | | | | | | | | | | | | | | | | 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: add PCI Express ASPM supportShaohua Li2008-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* PCI: Include PCI domain in PCI bus names on x86/x86_64Gary Hade2008-04-21
| | | | | | | | | | | | | | | 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.

* PCI: clean up search.c a lotGreg Kroah-Hartman2008-04-21
| | | | | | | | | | | | | | | | | | 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: Greg Kroah-Hartman <gregkh@suse.de>

| | * | natsemi: fix MMIO for PPC 44x platformsSergei Shtylyov2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver stores the PCI resource address into 'unsigned long' variable before calling ioremap() on it. This warrants a kernel oops when the registers are accessed on PPC 44x platforms which (being 32-bit) have PCI memory space mapped beyond 4 GB. The arch/ppc/ kernel has a fixup in ioremap() that creates an illusion of the PCI memory resources are mapped below 4 GB, but arch/powerpc/ code got rid of this trick, having instead CONFIG_RESOURCES_64BIT enabled.

| | * | [netdrvr] tulip: Better MWI workaround for 21143 rev 65 chip errataPeter Horton2008-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch works around the MWI bug on the DC21143 rev 65 Tulip by ensuring that the receive buffers don't end on a cache line boundary (as documented in the errata). This patch is required for the MIPS based Cobalt Qube/RaQ as supporting the extra PCI commands seems to reduce the chance of a hard lockup between the Tulip and the PCI bridge.

| | * | [netdrvr] tulip/winbond-840: don't let tulip.h symbol stomp oursJeff Garzik2008-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | winbond-840 shares tulip.h with the tulip driver, because they share many (but not all) of the same register definitions. This is useful for the register definitions, but not helpful when it comes to symbols that are shared among the tulip driver's C modules, but not meant to be shared outside that one driver. Thus, PKT_BUF_SZ is a symbol internal to tulip, but it was intruding upon a similar symbol in winbond-840's namespace. This was not a problem as long as the two symbols had the same value, but upcoming patches result in differing symbol values. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having the id field be an int was making more complex bus topologies excessively difficult. For now, just convert it to a string, and change all instances of "bus->id = val" to snprintf(id, MII_BUS_ID_LEN, "%x", val).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Poll the completed TX frames in gfar_poll(). This prevents the tx completion interrupt from interfering with processing of received frames. We also disable hardware rx coalescing when NAPI is enabled.
