Aaronwu,
Please help!
I have tried a couple of changes and can't get rid of the CPLB miss
I reviewed http://ez.analog.com/message/1335#1335, but I don't know how to add a cplb entry, please help me there
Below are the changes I made and at the end is a boot capture and the CPLB miss
I modified mem_map.h as such
/* Async Memory Banks */
/* //JK Added banks 4-7 */
#define ASYNC_BANK7_BASE 0x20700000 /* Async Bank 7 */
#define ASYNC_BANK7_SIZE 0x00100000 /* 1M */
#define ASYNC_BANK6_BASE 0x20600000 /* Async Bank 6 */
#define ASYNC_BANK6_SIZE 0x00100000 /* 1M */
#define ASYNC_BANK5_BASE 0x20500000 /* Async Bank 5 */
#define ASYNC_BANK5_SIZE 0x00100000 /* 1M */
#define ASYNC_BANK4_BASE 0x20400000 /* Async Bank 4 */
#define ASYNC_BANK4_SIZE 0x00100000 /* 1M */
#define ASYNC_BANK3_BASE 0x20300000 /* Async Bank 3 */
#define ASYNC_BANK3_SIZE 0x00100000 /* 1M */
#define ASYNC_BANK2_BASE 0x20200000 /* Async Bank 2 */
#define ASYNC_BANK2_SIZE 0x00100000 /* 1M */
#define ASYNC_BANK1_BASE 0x20100000 /* Async Bank 1 */
#define ASYNC_BANK1_SIZE 0x00100000 /* 1M */
#define ASYNC_BANK0_BASE 0x20000000 /* Async Bank 0 */
#define ASYNC_BANK0_SIZE 0x00100000 /* 1M */
I found this in mmu_context.h and changed it
/*//JK if (unlikely(addr >= ASYNC_BANK0_BASE && addr < ASYNC_BANK3_BASE + ASYNC_BANK3_SIZE)) */
if (unlikely(addr >= ASYNC_BANK0_BASE && addr < ASYNC_BANK7_BASE + ASYNC_BANK7_SIZE))
page = (addr - (ASYNC_BANK0_BASE - _ramend)) >> 12;
else
I hunted down all the ASYNC_BANK3_BASE and size and changed them to ASYNC_BANK7_BASE and size
and I am still getting the CPLB miss
