| query_info [IN] |
A query identification that indicates the item to
be queried:
- ALF_QUERY_NUM_ACCEL: Returns the number
of accelerators in the system.
- ALF_QUERY_HOST_MEM_SIZE: Returns the memory size of control
nodes up to 4T bytes, in units of kilobytes (2^10 bytes). When the size of
memory is more than 4T bytes, the total reported memory size is (ALF_QUERY_HOST_MEM_SIZE_EXT*4T
+ ALF_QUERY_HOST_MEM_SIZE*1K) bytes. In case of systems where
virtual memory is supported, this should be the maximum size of one contiguous
memory block that a single user space application could allocate.
- ALF_QUERY_HOST_MEM_SIZE_EXT: Returns the memory size
of control nodes, in units of 4T bytes (2^42 bytes).
- ALF_QUERY_ACCEL_MEM_SIZE: Returns the memory size of
accelerator nodes up to 4T bytes, in units of kilo bytes (2^10 bytes) . When
the size of memory is more than 4T bytes, the total reported memory size is
(ALF_QUERY_ACCEL_MEM_SIZE_EXT*4T + ALF_QUERY_ACCL_MEM_SIZE*1K)
bytes. For systems where virtual memory is supported, this should be the maximum
size of one contiguous memory block that a single user space application could
allocate.
- ALF_QUERY_ACCEL_MEM_SIZE_EXT: Returns the memory size
of accelerator nodes, in units of 4T bytes (2^42 bytes).
- ALF_QUERY_HOST_ADDR_ALIGN: Returns the basic requirement
of memory address alignment on control node side, in exponential of 2. A zero
stands for byte aligned address. A 4 is to align by 16 byte boundaries.
- ALF_QUERY_ACCEL_ADDR_ALIGN: Returns the basic requirement
of memory address alignment on accelerator node side, in exponential of 2.
A zero stands for byte aligned address. An 8 is to align by 256 byte boundaries
- ALF_QUERY_DTL_ADDR_ALIGN: Returns the address alignment
of data transfer list entries, in exponential of 2. A zero stands for byte
aligned address. An 8 is to align by 256 byte boundaries.
- ALF_QUERY_ACCEL_ENDIAN_ORDER:
- ALF_ENDIAN_ORDER_BIG
- ALF_ENDIAN_ORDER_LITTLE
- ALF_QUERY_HOST_ENDIAN_ORDER:
- ALF_ENDIAN_ORDER_BIG
- ALF_ENDIAN_ORDER_LITTLE
