SATA controller implemented in FPGA can write time stamps into specific memory region with 1/75 usec resolution. This feature called ''datascope'' was used to debug the controller itself, but it can also be used to debug or profile software. Each record in memory is a 32 bit value which is composed of a time stamp (28 lower bits) and a user defined tag (3 bits):
0x<8 + user tag><time stamp>
To add a time stamp, write a user defined tag to a specific memory location in the SATA controller's memory region. The controller will combine the tag with timer value and write it to memory.

Here is a short example of using datascope in driver's code. First, create a couple of global (for simplicity) variables, one is a pointer to the ''datascope'' register and the other is a flag (optional) which enables writing to the register:
static void __iomem *dscope_reg = NULL;
static unsigned int dscope_en = 0;

Second, create memory mapping for ''datascope'' register somewhere in start up code:

const unsigned long reg_addr = 0x80000178;

// initialize data scope
if (dscope_reg == NULL) {
dscope_reg = ioremap(reg_addr, 4);
if (dscope_reg == NULL)
printk(KERN_ERR "Can not ioremap data scope register\n");
else
dscope_en = 1;
}
}
Here, ''reg_addr'' is the ''datascope'' register address which consists of the following parts: 0x80000000 is the start address of AHCI controller memory registers, 0x100 is port 0 start address and 0x78 is one register in vendor specific register space (0x70 - 0x7f, see Serial ATA Advanced Host Controller Interface specification);

Third, remove ''datascope'' memory mapping when finished:
if (dscope_reg != NULL) {
iounmap(dscope_reg);
dscope_reg = NULL;
}

Invoke this function from code to set time stamp with tag ''tag'':
void dscope_timestamp(unsigned int cmd)
{
uint32_t data;

if (dscope_reg != NULL && dscope_en) {
data = tag & 0x7;
iowrite32(data, dscope_reg);
}
}

''Datascope'' writes time stamps to a memory region starting from 0x80001000 and occupying one memory page. In-camera python script can be used to watch the content of this memory region:
# cd /usr/local/bin/; python
>>> import x393_mem
>>> mem = x393_mem.X393Mem(1,0,1)
>>> _=mem.mem_dump(0x80001000, 100, 4)
The controller can use this memory region for debug output during its operation. If such interference is undesirable - remove AHCI driver:
modprobe -r ahci_elphel
