Adds the pSeries platform implementation for a new PCI API which can be used to issue various types of PCI-E reset, including PCI-E warm reset and PCI-E hot reset. This is needed for an ipr PCI-E adapter which does not properly implement BIST. Running BIST on this adapter results in PCI-E errors. The only reliable reset mechanism that exists on this hardware is PCI Fundamental reset (warm reset).

It appears that EEH is improperly enabled for some Power4 systems. On these systems, the ibm,set-eeh-option returns a value of success even when EEH is not supported on the given node. Thus, an explicit check for support is required. During boot, on power4, without this patch, one sees messages similar to: EEH: event on unsupported device, rc=0 dn=/pci@400000000110/IBM,sp@1 EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2 EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2,2 etc. The patch makes these go away. Without this patch, EEH recovery does seem to work correctly for at least some devices (I tested ethernet e1000), but fails to recover others (the Emulex LightPulse LPFC, most notably). Off the top of my head, I don't remember why some devices are affected, but not others. The PAPR indicates that the correct way to test for EEH is as done in this patch; its not clear to me if this was in the PAPR all along, or recently added; if it was there all along, its not clear to me why this hadn't been fixed long ago. I suspect only certain firmware levels are affected. Signed-off-by: NLinas Vepstas <linas@austin.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

Bug fix: when marking a slot as frozen, we forgot to mark pci device itself as frozen. (we did manage to mark the pci children, but forget the parent itself.)

由 Benjamin Herrenschmidt 提交于
This removes statically assigned platform numbers and reworks the powerpc platform probe code to use a better mechanism. With this, board support files can simply declare a new machine type with a macro, and implement a probe() function that uses the flattened device-tree to detect if they apply for a given machine. We now have a machine_is() macro that replaces the comparisons of _machine with the various PLATFORM_* constants. This commit also changes various drivers to use the new macro instead of looking at _machine.
