dax_adi(3DAX) DAX Library Functions dax_adi(3DAX)
NAME
dax_adi - DAX support for ADI
DESCRIPTION
The functions in the libdax library check for ADI errors in their input
and output vectors if ADI is enabled for those pages when the functions
are called. But the functions check only the first cache line of each
vector. This includes the following DAX function arguments:
dax_vec_t *src Checks src->data
dax_vec_t *dst Checks dst->data
dax_vec_t *widths Checks widths->data
dax_vec_t *runs Checks runs->data
dax_vec_t *mask Checks mask->data
dax_vec_t *bitmap Checks bitmap->data
dax_zip_t *codec Checks the codec. If the dax_zip_create_contig()
function creates the codec, this is the buffer
passed to that function, else this is the memory
allocated by libdax.
Also, the ADI version in all output cache lines is set to the version
available in the dst->data output pointer.
If an ADI mismatch occurs during the execution of libdax library code,
the process receives an ADI mismatch exception. If an ADI mismatch
occurs when DAX accesses a vector, the operation completes with the
DAX_EADI status. The latter mismatch can occur if the application
changes the ADI value of a cache line between the time the function is
called and the time that DAX starts an operation.
