Coremark porting to Android

1. Coremark 定位在 single core (CPU) 的測試
2. Readme.txt 提到，需要修改 "adjust <core_portme.mak>, <core_portme.h> (and possibly <core_portme.c>) according to the specific platform used."
3. 先 copy 一份 config 到 ./linux/
4. 首先 "make PORT_DIR=linux clean"
5. 修改 "linux/core_portme.mak" / "linux/core_portme.c" / "linux/core_portme.h" / "Makefile"
• core_poartme.mak
• 
  
#CC = gcc
CC = /home/xxx/arm-none-linux-gnueabi-gcc
PORT_CFLAGS = -O2
FLAGS_STR = "$(PORT_CFLAGS) $(XCFLAGS) $(XLFLAGS) $(LFLAGS_END)"
CFLAGS = $(PORT_CFLAGS) -I$(PORT_DIR) -I. -DFLAGS_STR=\"$(FLAGS_STR)\" -static
LFLAGS_END += -lrt

  
6. 可編譯成幾種不同 mode:
• General mode for default setting
• make PORT_DIR=linux
• General mode with iteration 
• make PORT_DIR=linux -DPERFORMANCE_RUN=1 -DITERATIONS=1000
• Validation mode 
• make PORT_DIR=linux -DVALIDATION_RUN=1
• Debug mode for incorrect CRC
• make PORT_DIR=linux XCFLAGS="-DCORE_DEBUG=1"
• Parallel mode_FORK
• make PORT_DIR=linux XCFLAGS="-g -DMULTITHREAD=4 -DUSE_FORK=1"
• Parallel mode_PTHREAD
• Modify core_portme.mak (LFLAGS_END += -lrt –lpthread)
• make PORT_DIR=linux XCFLAGS="-DMULTITHREAD=4 -DUSE_PTHREAD"
• Profile mode (TBT)
• Mem allocation_malloc
• 修改 core_portme.h
• define MEM_METHOD MEM_MALLOC
• 配合上面的 make
• Mem allocation_static
• 修改 core_portme.h
• define MEM_METHOD MEM_STATIC
• 配合上面的 make
• Mem allocation_stack
• 修改 core_portme.h
• define MEM_METHOD MEM_STACK
• 配合上面的 make
7. 執行 ./coremark or ./coremark 0x0 0x0 0x66 0 7 1 2000
8. 結果就看 Total ticks / Total time (secs) / Iterations/Sec / Iterations / Compiler flags
