/* Some notes on the ptid usage on this target.

|

|
The pid field represents the kvm inferior instance. Currently,
|
||||||
|
we don't support multiple kvm inferiors, but we start at 1
|
||||||
|
anyway. The lwp field is set to != 0, in case the core wants to
|
||||||
|
refer to the whole kvm inferior with ptid(1,0,0).
|
||||||
|
|
||||||
|
If kvm is made to export running processes as gdb threads,
|
||||||
|
the following form can be used:
|
||||||
|
ptid (1, 1, 0) -> kvm inferior 1, in kernel
|
||||||
|
ptid (1, 1, 1) -> kvm inferior 1, process 1
|
||||||
|
ptid (1, 1, 2) -> kvm inferior 1, process 2
|
||||||
|
ptid (1, 1, n) -> kvm inferior 1, process n
