Currently, there is no guarantee that the memory bins will be allocated contiguously. However, there are assumptions in the code that bins are allocated contiguously, such as the GCD init code requiring a free memory region be large enough for a contiguous bin range on DXE Core init. Ensuring contiguous bins also makes a cleaner model for the bins and keeps the memory map in a more standard configuration between different configurations, as platforms today can pass a resource descriptor HOB to DXE core to describe the bin range and this only supports a contiguous range. This also sets up reusing the memory bin logic for PEI memory bin support which will use the aforementioned resource descriptor HOB to pass the bin range to DXE. This commit updates CoreAddMemoryDescriptor() to allocate a contiguous range. Signed-off-by: Oliver Smith-Denny <osde@microsoft.com> |
