* BaseMemoryLibSse2: Take advantage of write combining buffersCompostella, Jeremy2020-10-1610-38/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current SSE2 implementation of the ZeroMem(), SetMem(), SetMem16(), SetMem32 and SetMem64 functions is writing 16 bytes per 16 bytes. It hurts the performances so bad that this is even slower than a simple 'rep stos' (4% slower) in regular DRAM. To take full advantages of the 'movntdq' instruction it is better to "queue" a total of 64 bytes in the write combining buffers. This patch implement such a change. Below is a table where I measured (with 'rdtsc') the time to write an entire 100MB RAM buffer. These functions operate almost two times faster. | Function | Arch | Untouched | 64 bytes | Result | |----------+------+-----------+----------+--------| | ZeroMem | Ia32 | 17765947 | 9136062 | 1.945x | | ZeroMem | X64 | 17525170 | 9233391 | 1.898x | | SetMem | Ia32 | 17522291 | 9137272 | 1.918x | | SetMem | X64 | 17949261 | 9176978 | 1.956x | | SetMem16 | Ia32 | 18219673 | 9372062 | 1.944x | | SetMem16 | X64 | 17523331 | 9275184 | 1.889x | | SetMem32 | Ia32 | 18495036 | 9273053 | 1.994x | | SetMem32 | X64 | 17368864 | 9285885 | 1.870x | | SetMem64 | Ia32 | 18564473 | 9241362 | 2.009x | | SetMem64 | X64 | 17506951 | 9280148 | 1.886x | Signed-off-by: Jeremy Compostella <jeremy.compostella@intel.com> Reviewed-by: Liming Gao <gaoliming@byosoft.com.cn>

* MdePkg/BaseMemoryLib*: check for zero length in ZeroMem ()Ard Biesheuvel2016-11-041-1/+5
| | | | | | | | | | | | | | | | Unlike other string functions in this library, ZeroMem () does not return early when the length of the input buffer is 0. So add the same to ZeroMem () as well, for all implementations of BaseMemoryLib living under MdePkg/ This fixes an issue with the ARM implementation of BaseMemoryLibOPtDxe, whose InternalMemZeroMem code does not expect a length of 0, and always writes at least a single byte.
