2011-03-31x86, amd-nb: Rename CPU PCI id define for F4Borislav Petkov
With increasing number of PCI function ids, add the PCI function id in the define name instead of its symbolic name in the BKDG for more clarity. This renames function 4 define.

2011-02-07x86, amd: Support L3 Cache Partitioning on AMD family 0x15 CPUsHans Rosenfeld
L3 Cache Partitioning allows selecting which of the 4 L3 subcaches can be used for evictions by the L2 cache of each compute unit. By writing a 4-bit hexadecimal mask into the the sysfs file /sys/devices/system/cpu/cpuX/cache/index3/subcaches, the user can set the enabled subcaches for a CPU. The settings are directly read from and written to the hardware, so there is no way to have contradicting settings for two CPUs belonging to the same compute unit. Writing will always overwrite any previous setting for a compute unit.

2011-01-11x86: Use PCI method for enabling AMD extended config space before MSR methodJan Beulich
While both methods should work equivalently well for the native case, the Xen Dom0 case can't reliably work with the MSR one, since there's no guarantee that the virtual CPUs it has available fully cover all necessary physical ones. As per the suggestion of Robert Richter the patch only adds the PCI method, but leaves the MSR one as a fallback to cover new systems the PCI IDs of which may not have got added to the code base yet. The only change in v2 is the breaking out of the new CPI initialization method into a separate function, as requested by Ingo.

2010-11-18x86, cacheinfo: Cleanup L3 cache index disable supportHans Rosenfeld
Adaptions to the changes of the AMD northbridge caching code: instead of a bool in each l3 struct, use a flag in amd_northbridges.flags to indicate L3 cache index disable support; use a pointer to the whole northbridge instead of the misc device in the l3 struct; simplify the initialisation; dynamically generate sysfs attribute array.

2010-11-18x86, amd-nb: Cleanup AMD northbridge caching codeHans Rosenfeld
Support more than just the "Misc Control" part of the northbridges. Support more flags by turning "gart_supported" into a single bit flag that is stored in a flags member. Clean up related code by using a set of functions (amd_nb_num(), amd_nb_has_feature() and node_to_amd_nb()) instead of accessing the NB data structures directly. Reorder the initialization code and put the GART flush words caching in a separate function.

2010-11-18x86, amd-nb: Complete the rename of AMD NB and related codeHans Rosenfeld
Not only the naming of the files was confusing, it was even more so for the function and variable names. Renamed the K8 NB and NUMA stuff that is also used on other AMD platforms. This also renames the CONFIG_K8_NUMA option to CONFIG_AMD_NUMA and the related file k8topology_64.c to amdtopology_64.c. No functional changes intended.

2010-09-20x86, k8: Rename k8.[ch] to amd_nb.[ch] and CONFIG_K8_NB to CONFIG_AMD_NBAndreas Herrmann
The file names are somehow misleading as the code is not specific to AMD K8 CPUs anymore. The files accomodate code for other AMD CPU northbridges as well. Same is true for the config option which is valid for AMD CPU northbridges in general and not specific to K8.
