| | | | | | | | | | | | | | | | | | Define a variant of the flat-map that was historically defined as PageMap1, which allocated about 4MB in an array to map all possible pages to their status as part of a span. This version (under Windows only) uses VirtualAlloc to effectively reserve the space, and then only commit the space when it is necessary to ensure it is available. The bulk of the code is almost directly modeled on PageMap1, which is also defined in pagemap.h. bug=30010 r=willchan Review URL: http://codereview.chromium.org/460155 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@34422 0039d316-1c4b-4281-b951-d872f2087c98

| | | | | | | | | | This change also reworks the tcmalloc dependency to be added only to chrome and test_shell, instead of base. This is necessary since otherwise tcmalloc will be double initialized (by both the main executable and dlopen'd shared objects like the npapitestplugin.so). Add valgrind suppressions. This are invalid reads on static initialization in the VDSOSupport module. I haven't investigated it yet, but I suspect they're benign.

See: http://codereview.chromium.org/235022 Also included change to browser_about_handler.cc to fix build, and I set TCMALLOC_RELEASE_RATE to 1.0 on line 40 of page_heap.cc (I think this was an inadvertent rollback element). r=antonm Review URL: http://codereview.chromium.org/257009 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@27692 0039d316-1c4b-4281-b951-d872f2087c98

* Rounds up VirtualAlloc calls on windows to dwAllocationGranularity to ↵jamesr@chromium.org2009-09-251-19/+20
| | | | | | | | | | | | | | | | | | | | | | prevent fragmentation Actually on Windows VirtualAlloc'ated address might have bigger alignment than reported by SYSTEM_INFO.dwPageSize, see SYSTEM_INFO.dwAllocationGranularity. As coalescing of spans in tcmalloc requires that those spans are physically adjacent, using smaller alignment inhibited coalescing. Additional benefit is we now require ways less memory at least in some case. Also adds assert()s for alignment values that would lead to pathological virtual address space waste. No current callers pass in alignment values other than kPageSize and it's unlikely anyone will. Original patch and discussion was at http://codereview.chromium.org/235003 Patch by: antonm@chromium.org BUG=22701 TEST=Manually checked test page that did 10m XHR. Memory use goes from >2GB and a crash to 102MB. Membuster shows the change is roughly within noise and possibly a very slight regression ( <<5% ).
