.ML Output Field Descriptions

Output from .ML appears in one of is of the following forms:

 hal=0006 pal=%ffe61048  har=01b8  hptda=009f  pgoff=00000  f=021

 hal=000a pal=%ffe61068  har=0208  cs=0056 ds=d446 cref=001 f=13

 hal=0011 pal=%ffe610a0  palnext=ffe610a8      pgoff=00000  f=000

Each of the fields has the following meaning:

hal

The handle of the alias record being formatted. This is the unique identifier by which the alias record is known.
har
The handle of the arena record which represents the aliasing linear address range. The arena record for the aliased linear address is pointed to by the link field of the aliasing har.
hptda
The handle of the PTDA object of the context which has been aliased. This may also take the value of a system owner when memory is in the process of being freed.
pgoff
The page offset into the arena which is aliased. Note: aliases may map partial objects. The number of pages aliased may be determined from the arena record which represents the aliased memory. Use .MLC hal to display this information.
cs
The Code Selector created to alias R/W memory.
ds
The Data Selector which has been aliased by a Code selector.
cref
The reference count for the number of time a Code Selector alias has been requested for a given Data Selector.
palnext
The pointer to the next free alias record.
f
Alias record flags. For Selector Aliases this is a 6-bit field, for other aliases this is a 12-bit field.
