x86: track memtype for RAM in page struct

2008-10-10T17:29:18Z

Track the memtype for RAM pages in page struct instead of using the memtype list. This avoids the explosion in the number of entries in memtype list (of the order of 20,000 with AGP) and makes the PAT tracking simpler. We are using PG_arch_1 bit in page->flags. We still use the memtype list for non RAM pages. Signed-off-by: Suresh Siddha Signed-off-by: Venkatesh Pallipadi Signed-off-by: Ingo Molnar

x86, cpa: remove cpa pool code

2008-10-10T17:29:16Z

Interrupt context no longer splits large page in cpa(). So we can do away with cpa memory pool code. Signed-off-by: Suresh Siddha Cc: Suresh Siddha Cc: arjan@linux.intel.com Cc: venkatesh.pallipadi@intel.com Cc: jeremy@goop.org Signed-off-by: Ingo Molnar

x86, pageattr: introduce APIs to change pageattr of a page array

2008-08-21T11:47:45Z

Add array interface APIs of pageattr. page based cache flush is quite slow for a lot of pages. If pages are more than 1024 (4M), the patch will use a wbinvd(). We have a simple test here (run a 3d game - open arena), nearly all agp memory allocation are small (< 1M), so suppose this will not impact runtime performance.

Revert "introduce two APIs for page attribute"

2008-08-21T11:46:33Z

This reverts commit 1ac2f7d55b7ee1613c90631e87fea22ec06781e5.

introduce two APIs for page attribute

2008-08-15T14:30:45Z

Introduce two APIs for page attribute. flushing tlb/cache in every page attribute is expensive. AGP gart usually will do a lot of operations to change a page to uc, new APIs can reduce flush.

x86: consolidate header guards

2008-07-22T19:31:34Z

This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum

x86: add comments to describe the new api's in cacheflush.h

2008-04-17T15:41:31Z

The new cacheflush.h API's didn't have any comments describing how they're to be used yet and the conventions around these functions. This patch adds comments to this effect; in order for that to be a logical series, some prototypes had to move around. Signed-off-by: Arjan van de Ven Signed-off-by: Ingo Molnar

x86: add set_memory_4k to pageattr.c

2008-04-17T15:41:30Z

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.
