Heiko Schocher 95c6f6d34d ARM V7 (OMAP): add data cache support, test on Beagle board ... Add data cache support for ARM V7 systems. Used cache flush functions from linux:arch/arm/mm/cache-v7.S developed from Catalin Marinas. Enable "cache" command on Beagle board and test performance. Test 1: Loading 127 MB of data from NAND flash into RAM: Instr. Cache off on on Data Cache off off on -------------------------------------------------- Beagle (Cortex A8) 116s 106s 30.3s = x 3.8 Test 2: uncompressing a gzipped image from RAM to RAM (size compressed: 6.5 MiB, uncompressed: 35 MiB): Instr. Cache off on on Data Cache off off on -------------------------------------------------- Beagle (Cortex A8) 1.84s 1.64s 0.12s = x 15.3 Portions of this work were supported by funding from the CE Linux Forum.
