| H A D | file.c | 69a2f00c Mon Nov 20 11:45:00 CST 2006 Dwayne Grant McConnell <decimal@us.ibm.com> [POWERPC] spufs: Implement /mbox_info, /ibox_info, and /wbox_info.
This patch implements read only access to
/mbox_info - SPU Write Outbound Mailbox
/ibox_info - SPU Write Outbound Interrupt Mailbox
/wbox_info - SPU Read Inbound Mailbox
These files are used by gdb in order to look into the current mailbox
queues without changing the contents at the same time. They are
not meant for general programming use, since the access requires
a context save and is therefore rather slow.
It would be good to complement this patch with one that adds
write support as well.
