* x86: cleanup - rename VM_MASK to X86_VM_MASKgorcunov@gmail.com2008-04-173-6/+6
| | | | | | | | | | | This patch renames VM_MASK to X86_VM_MASK (which in turn defined as alias to X86_EFLAGS_VM) to better distinguish from virtual memory flags. We can't just use X86_EFLAGS_VM instead because it is also used for conditional compilation Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | The memory resource is also used for main memory, and we need it to allocate physical addresses for memory hotplug. Knobbling io space is enough to get the job done anyway.

* x86: change naming of cpu_initialized_mask for xenGlauber Costa2008-04-171-3/+3
| | | | | | | | | | xen does not use the global cpu_initialized mask, but rather, a specific one. So we change its name so it won't conflict with the upcoming movement of cpu_initialized_mask from smp_64.h to smp_32.h.

* x86: split large page mapping for AMD TSEGAndi Kleen2008-04-171-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AMD SMM protected memory is part of the address map, but handled internally like an MTRR. That leads to large pages getting split internally which has some performance implications. Check for the AMD TSEG MSR and split the large page mapping on that area explicitely if it is part of the direct mapping. There is also SMM ASEG, but it is in the first 1MB and already covered by the earlier split first page patch. Idea for this came from an earlier patch by Andreas Herrmann On a RevF dual Socket Opteron system kernbench shows a clear improvement from this: (together with the earlier patches in this series, especially the split first 2MB patch) [lower is better] no split stddev split stddev delta Elapsed Time 87.146 (0.727516) 84.296 (1.09098) -3.2% User Time 274.537 (4.05226) 273.692 (3.34344) -0.3% System Time 34.907 (0.42492) 34.508 (0.26832) -1.1% Percent CPU 322.5 (38.3007) 326.5 (44.5128) +1.2% => About 3.2% improvement in elapsed time for kernbench. With GB pages on AMD Fam1h the impact of splitting is much higher of course, since it would split two full GB pages (together with the first 1MB split patch) instead of two 2MB pages. I could not benchmark a clear difference in kernbench on gbpages, so I kept it disabled for that case That was only limited benchmarking of course, so if someone was interested in running more tests for the gbpages case that could be revisited (contributions welcome) I didn't bother implementing this for 32bit because it is very unlikely the 32bit lowmem mapping overlaps into the TSEG near 4GB and the 2MB low split is already handled for both.

* x86: don't use large pages to map the first 2/4MB of memoryAndi Kleen2008-04-172-1/+18
| | | | | | | | | | | | | | | | | | | | | | | Intel recommends to not use large pages for the first 1MB of the physical memory because there are fixed size MTRRs there which cause splitups in the TLBs. On AMD doing so is also a good idea. The implementation is a little different between 32bit and 64bit. On 32bit I just taught the initial page table set up about this because it was very simple to do. This also has the advantage that the risk of a prefetch ever seeing the page even if it only exists for a short time is minimized. On 64bit that is not quite possible, so use set_memory_4k() a little later (in check_bugs) instead.

* x86: add set_memory_4k to pageattr.cAndi Kleen2008-04-171-4/+16
| | | | | | | | | | | | | | | | | | | Add a new function to force split large pages into 4k pages. This is needed for some followup optimizations. I had to add a new field to cpa_data to pass down the information that try_preserve_large_page should not run. Right now no set_page_4k() because I didn't need it and all the specialized users I have in mind would be more comfortable with pure addresses. I also didn't export it because it's unlikely external code needs it.

* x86: implement true end_pfn_mapped for 32bitAndi Kleen2008-04-171-0/+4
| | | | | | | | | | | | | | Even on 32bit 2MB pages can map more memory than is in the true max_low_pfn if end_pfn is not highmem and not aligned to 2MB. Add a end_pfn_map similar to x86-64 that accounts for this fact. This is important for code that really needs to know about all mapping aliases.
