Subject: [PATCH] memattrs: add debug attribute
|
|
|
|
Extend the MemTxAttrs to include 'debug' flag. The flag can be used as
|
|
general indicator that operation was triggered by the debugger.
|
|
|
|
Later in the patch series we set the debug=1 when issuing a memory access
|
|
from the gdbstub or HMP commands. This patch is prerequisite to support
|
|
debugging the encrypted guest. If we see request with debug=1 then we
|
|
will need to use encryption APIs to access the guest memory.
