| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer Intel platforms support more than one method to report H/W event. On this kind of platform, H/W event report can adopt new method and traditional EDAC method should be disabled. Moreover, if EDAC event report method is set to *force*, it means event must be reported via EDAC interface. IOW, it overrides the default event report policy.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add pcie error interrupt edac support for mpc85xx, p3041, p4080, and p5020. The mpc85xx uses the legacy interrupt report mechanism - the error interrupts are reported directly to mpic. While the p3041/ p4080/p5020 attaches the most of error interrupts to interrupt zero. And report error interrupts to mpic via interrupt 0. This patch can handle both of them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | dct_base and dct_limit obtain 32 bit register values when they read their respective pci config space registers. A left shift beyond 32 bits will cause them to wrap around. Similar case for chan_addr as can be seen from the bug report (link below). In the patch, we rectify this by casting chan_addr to u64 and by comparing dct_base and dct_limit against properly shifted sys_addr in order to compare the correct bits.

| * | amd64_edac: Fix single-channel setupsBorislav Petkov2013-07-291-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It can happen that configurations are running in a single-channel mode even with a dual-channel memory controller, by, say, putting the DIMMs only on the one channel and leaving the other empty. This causes a problem in init_csrows which implicitly assumes that when the second channel is enabled, i.e. channel 1, the struct dimm hierarchy will be present. Which is not. So always allocate two channels unconditionally. This provides for the nice side effect that the data structures are initialized so some day, when memory hotplug is supported, it should just work out of the box when all of a sudden a second channel appears.
