Where is Xhash() function defined ? It has called from driver-btm-DASH.c but i could not see anywhere that the function decribed declared ..
in
Code:
x11/xcoin.c
Code:
void Xhash(void *state, const void *input)
{
//printf("-----------------Xhash-------------------\n");
DATA_ALIGN16(unsigned char hashbuf[128]);
DATA_ALIGN16(size_t hashptr);
DATA_ALIGN16(sph_u64 hashctA);
DATA_ALIGN16(sph_u64 hashctB);
int speedrun[] = {0, 1, 3, 4, 6, 7 };
int i;
DATA_ALIGN16(unsigned char hash[128]);
/* proably not needed */
memset(hash, 0, 128);
// blake1-bmw2-grs3-skein4-jh5-keccak6-luffa7-cubehash8-shavite9-simd10-echo11
#ifdef DUMP_INFO_PERSTEP
char strInfo[1024];
unsigned char *pByte;
uint64_t tmpValue;
char ret_line[3]={'\r','\n','\0'};
printf("-----------------X11 input-------------------\n");
pByte=(unsigned char *)input;
BinToHexStr(strInfo,pByte,128);
printf("input=%s\n",strInfo);
#endif
//---blake1---
DECL_BLK;
BLK_I;
BLK_W;
BLK_C;
#ifdef DUMP_INFO_PERSTEP
printf("-----------------blake output-------------------\n");
pByte=(unsigned char *)hash;
BinToHexStr(strInfo,pByte,128); // defined unsigned char hash[128]
printf("hash=%s\n",strInfo);
#endif
So if we return from here ? Are going to get grostl hash as output ?{
//printf("-----------------Xhash-------------------\n");
DATA_ALIGN16(unsigned char hashbuf[128]);
DATA_ALIGN16(size_t hashptr);
DATA_ALIGN16(sph_u64 hashctA);
DATA_ALIGN16(sph_u64 hashctB);
int speedrun[] = {0, 1, 3, 4, 6, 7 };
int i;
DATA_ALIGN16(unsigned char hash[128]);
/* proably not needed */
memset(hash, 0, 128);
// blake1-bmw2-grs3-skein4-jh5-keccak6-luffa7-cubehash8-shavite9-simd10-echo11
#ifdef DUMP_INFO_PERSTEP
char strInfo[1024];
unsigned char *pByte;
uint64_t tmpValue;
char ret_line[3]={'\r','\n','\0'};
printf("-----------------X11 input-------------------\n");
pByte=(unsigned char *)input;
BinToHexStr(strInfo,pByte,128);
printf("input=%s\n",strInfo);
#endif
//---blake1---
DECL_BLK;
BLK_I;
BLK_W;
BLK_C;
#ifdef DUMP_INFO_PERSTEP
printf("-----------------blake output-------------------\n");
pByte=(unsigned char *)hash;
BinToHexStr(strInfo,pByte,128); // defined unsigned char hash[128]
printf("hash=%s\n",strInfo);
#endif
How is it invoking asics ?
i think we need:
1) made this mode in the function, for go i grs3;
2) recomplie the cgminer
3) rebuild the firmware whit this chage
4) Test it
Anyone can help for this step? i think we are on the right track
I really could not understand what is going on that code, it takes each algorithm step by step but how ? because there is no any assignment , just memcpy so how is it interacting with asics ?
I don't see any memcpy above. However, memcpy would allow you to 'write' to a logical memory location where the ASIC is. My guess, without having a full review, is that the memory location is used as both as INPUT for data to be hashed and an OUTPUT for the resulting hash. In most instances the input/output portion of the memory are simply predefined offsets.
