Hao Wu d8162f5b32 MdeModulePkg MemoryProfile: ASSERT to ensure 'DriverInfoData' is not NULL
Code logic ensures that the pointer 'DriverInfoData' will not be NULL when
it is used.

Liming Gao 467d5f6b30 MdeModulePkg: DxeCore MemoryPool Algorithm Update
Use 128 bytes as the start size region to be same to previous one.

64 bytes is small as the first range. On X64 arch, POOL_OVERHEAD
takes 40 bytes, the pool data less than 24 bytes can be fit into
it. But, the real allocation is few that can't reduce its free pool
link list. And, the second range (64~128) has more allocation
that also increases the free pool link list of the first range.
Then, the link list will become longer and longer. When LinkList
check enable in DEBUG tip, the long link list will bring the
additional overhead and bad performance. Here is the performance
data collected in our X64 platform with DEBUG enable.
64  byte: 22 seconds in BDS phase
128 byte: 19.6 seconds in BDS phase

DescEnd will be clipped for alignment in CoreFindFreePagesI, and it
may fall below DescStart, when alignment is more than 16KB (included)
and both DescStart and original DescEnd fall into a single range of
such alignment. This results in a huge size (Negative number in
unsigned type) for this descriptor, fulfilling the allocation
requirement but failing to run ConvertPages; at last it causes
occasional failure of AllocatePages.

A simple comparison is added to ensure we would never get a negative

Ard Biesheuvel 6860b92c84 MdeModulePkg: serve allocations from higher-up bins if current bin is empty
This patch changes the allocation logic for the pool allocator to only
allocate additional pages if the requested allocation cannot be fulfilled
from the current bin or any of the larger ones. If there are larger blocks
available, they will be used to serve the allocation, and the remainder will
be carved up into smaller blocks using the existing carving up logic.
Note that all pool sizes are a multiple of the smallest pool size, so it is
guaranteed that the remainder will be carved up without spilling. Due to the
exponential nature of the pool sizes, the amount of work is logarithmic in
the size of the available block.

Ard Biesheuvel 7970100ccb MdeModulePkg: use correct granularity when allocating pool pages
After fixing the sanity check on the alignment of the runtime regions
in SVN revision #16630 ("MdeModulePkg/DxeMain: Fix wrong sanity check
in CoreTerminateMemoryMap()"), it is no longer possible to define a
runtime allocation alignment that is different from the boot time
allocation alignment.

For instance, #defining the following in MdeModulePkg/Core/Dxe/Mem/Imem.h
will hit the ASSERT () in MdeModulePkg/Core/Dxe/Mem/Page.c:1798

  #define EFI_ACPI_RUNTIME_PAGE_ALLOCATION_ALIGNMENT  (SIZE_64KB)
  #define DEFAULT_PAGE_ALLOCATION                     (EFI_PAGE_SIZE)

(which is needed for 64-bit ARM to adhere to the Server Base Boot
Requirements [SBBR], which stipulates that all runtime memory regions
should be naturally aligned multiples of 64 KB)

This patch fixes this use case by ensuring that the backing for the memory
pools is allocated in appropriate chunks for the memory type.

mdkinney d436d5ca09 Guarantee that free memory in the 4K page starting at address 0 is always cleared to 0. The algorithm is to clear page zero if it is registered with the DXE Core with type EfiConventionalMemory, and to also clear page zero if it is freed using the UEFI Boot Service FreePages(). This patch improves OS compatibility for OSes that may evaluate page 0 for legacy data structures. Before this patch, free memory may contain random values which induces random boot failures for some OSes. This patch may also help find NULL pointer bugs sooner because all of the fields in a data structure dereferenced through NULL will also be NULL now.
