| * | | amd64_edac: Cleanup NBCFG handlingBorislav Petkov2011-03-172-30/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fact whether we are chipkill capable or not does not have any bearing when computing the channel index on a ganged DCT configuration so remove that. Also, simplify debug statements. Finally, remove old error injection leftovers, while at it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

| * | | amd64_edac: Cleanup Dram Configuration registers handlingBorislav Petkov2011-03-172-37/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Restrict DCT ganged mode check since only Fam10h supports it * Adjust DRAM type detection for BD since it only supports DDR3 * Remove second and thus unneeded DCLR read in k8_early_channel_count() - we do that in read_mc_regs() * Cleanup comments and remove family names from register macros * Remove unused defines There should be no functional change resulting from this patch.

| * | | amd64_edac: Sanitize f10_get_base_addr_offsetBorislav Petkov2011-03-172-48/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function maps the system address to the normalized DCT address. Document what the code does for more clarity and wrap insane bitmasks in a more understandable macro which generates them. Also, reduce number of arguments passed to the function. Finally, rename this function to what it actually does. No functional change. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cleanup and simplify f10_determine_channel(); make it more readable. Also drop f10_map_intlv_en_to_shift() in favor of simply counting the bits in F1x124[DramIntlvEn] which is equivalent. There should be no functionality change resulting from this patch.

| * | | amd64_edac: Cleanup chipselect handlingBorislav Petkov2011-03-172-238/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a struct representing the DRAM chip select base/limit register pairs. Concentrate all CS handling in a single function. Also, add CS looping macros for cleaner, more readable code. While at it, adjust code to F15h. Finally, do smaller macro names cleanups (remove family names from register macros) and debug messages clarification. No functional change. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

| * | | amd64_edac: Add support for F15h DCT PCI config accessesBorislav Petkov2011-03-173-75/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | F15h "multiplexes" between the configuration space of the two DRAM controllers by toggling D18F1x10C[DctCfgSel] while F10h has a different set of registers for DCT0, and DCT1 in extended PCI config space. Add DCT configuration space accessors per family thus wrapping all the different access prerequisites. Clean up code while at it, shorten names.

* / amd64_edac: Fix DIMMs per DCTs outputBorislav Petkov2011-02-101-20/+8
|/ | | | | | | | | | | | amd64_debug_display_dimm_sizes() reports the distribution of the DIMMs on each DRAM controller and its chip select sizes. Thus, the last don't have anything to do with whether we're running in ganged DCT mode or not - their sizes don't change all of a sudden. Fix that by removing the ganged-check and dump DCT0's config for DCT1 when in ganged mode since they're identical.
