* Expand memory footprint to full 8MB cache.Patrick Williams2012-11-141-4/+4
| | | | | | | | | | | | | | If fake PNOR isn't being used, we can expand our memory space to the full 8MB cache. There will be follow up work with RTC: 49137 to support 4MB degraded caches for bring-up.

* 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.
