- In a combined PPU/SPU debugging session, we have to consider multiple
- address spaces: the PPU 32- or 64-bit address space, and the 32-bit
- local store address space for each SPU context. As it is currently
- not yet possible to use the program_space / address_space mechanism
- to represent this, we encode all those addresses into one single
- 64-bit address for the whole process. For SPU programs using overlays,
- this address space must also include separate ranges reserved for the
- LMA of overlay sections.
-
-
- The following combinations are supported for combined debugging:
-
- PPU address (this relies on the fact that PPC 64-bit user space
- addresses can never have the highest-most bit set):
-
- +-+---------------------------------+
- |0| ADDR [63] |
- +-+---------------------------------+
-
- SPU address for SPU context with id SPU (this assumes that SPU
- IDs, which are file descriptors, are never larger than 2^30):
-
- +-+-+--------------+----------------+
- |1|0| SPU [30] | ADDR [32] |
- +-+-+--------------+----------------+
-
- SPU overlay section LMA for SPU context with id SPU:
-
- +-+-+--------------+----------------+
- |1|1| SPU [30] | ADDR [32] |
- +-+-+--------------+----------------+
-
-
- In SPU stand-alone debugging mode (using spu-linux-nat.c),
- the following combinations are supported:
-
- SPU address:
-
- +-+-+--------------+----------------+
- |0|0| 0 | ADDR [32] |
- +-+-+--------------+----------------+
-
- SPU overlay section LMA:
-
- +-+-+--------------+----------------+
