This patch adds extended interrupt support for AMD Barcelona CPUs. The patch provides functions to setup MCE and IBS interrupt vectors. Compared to the previous K8 implementation the vector offsets are centrally handled now in apic_64.c. Thus, the APIC setup code is responsible for vector mappings. The vector mapping is hardcoded for now. Also macro definitions in apicdef.h has been updated. The patch is relative to x86/cleanup tree. --- arch/x86/kernel/apic_64.c | 26 +++++++++...

On Sat, 2007-11-17 00:20:20 +0100, Xavier Bestel <xavier.bestel@free.fr> wr= Erm... "ECC" means there are extra bits that, with small amount of errors, allow to recalculate the initial value. If you're getting error messages with ECC errors, that means that your RAM really looses its contents. You should fix your machine. (Check that eg. timings are correct with RAM's specification, ...) You're on risk. Really. MfG, JBG --=20 Jan-Benedict Glaw jbglaw@lug-owl.de ...

Virtually map the cpu areas. This allows bigger maximum sizes and to only populate the virtual mappings on demand. In order to use the virtual mapping capability the arch must setup some configuration variables in arch/xxx/Kconfig: CONFIG_CPU_AREA_VIRTUAL to y CONFIG_CPU_AREA_ORDER to the largest allowed size that the per cpu area can grow to. CONFIG_CPU_AREA_ALLOC_ORDER to the allocation size when the cpu area needs to grow. Use 0 here to guarantee order 0 allocations. The address to...

Typical use of per cpu memory for a small system of 8G 8p 4node is less than 64k per cpu memory. This is increasing rapidly for larger systems where we can get up to 512k or 1M of memory used for cpu storage. The maximum size allowed of the cpu area is 128MB of memory. The cpu area is placed in region 5 with the kernel, vmemmap and vmalloc areas.

Use the new cpu_alloc functionality to avoid per cpu arrays in struct zone. This drastically reduces the size of struct zone for systems with a large amounts of processors and allows placement of critical variables of struct zone in one cacheline even on very large systems. Another effect is that the pagesets of one processor are placed near one another. If multiple pagesets from different zones fit into one cacheline then additional cacheline fetches can be avoided on the hot paths when allocating...

Remove the fields in kmem_cache_cpu that were used to cache data from kmem_cache when they were in different cachelines. The cacheline that holds the per cpu array pointer now also holds these values. We can cut down the kmem_cache_cpu size to almost half. The get_freepointer() and set_freepointer() functions that used to be only intended for the slow path now are also useful for the hot path since access to the field does not require an additional cacheline anymore. This results in consistent use ...

Get the sizes of various pieces of data right when using three-level page tables. pgd and pmd entries remain at 32 bits in a 32-bit compilation because page tables will remain in low memory. So, PGDIR_SHIFT, the PTRS_PER_* values, set_pud, set_pmd are conditional on 64BIT. More use of phys_t is made when there are physical memory addresses floating around.
