| | | | | | | | | | | | | | | | | Created per-node arrays of CPU objects rather than a single array for the entire system. These are created dynamically as CPUs are enabled. Also disabled support for P7 due to the PIR layout being different and hence would have needed two different sets of assembly code. We have been running exclusively on the P8 Mambo model for a while.

* Live-lock issues in memory allocator.Patrick Williams2012-07-111-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * Debug tool for PageManager. * Support PageMgr allocations of non-2^k size. * Switch page-allocation to always be in kernel-mode. While investigating issue 44511, I noticed two problesm with the memory page allocator (PageManager). First, the allocator did not support allocations of pages which were not a power of 2, which would result in pages appearing to "leak". Second, in situations where a large allocation was requested and there was not a large chunk available, the allocation would enter a live-lock condition where coalescing would never occur. Switched the PageManager so that all allocations happen in kernel space. This allows us to force memory-release operations on the syscall path when we are out of memory and also put in place a task_yield call which will allow coalescing to eventually occur. Issue 44523 is suppose to fully resolve any of these live-lock paths.
