- Subject: [rfc/rfa] [4/4] SPU enhancements: GDB/MI extensions
Hello,
this patch makes the new "info spu" commands available via the GDB/MI
protocol. The Cell Broadband Engine IDE is already able to make use
of these commands and display the SPU status information.
It looks like these are the first platform-specific MI commands, so
I'd appreciate opinions on this ...
Eli, doc changes OK?
Bye,
Ulrich
ChangeLog:
* mi/mi-cmds.c (mi_cmds): Add -spu-info-event, -spu-info-signal,
-spu-info-mailbox, -spu-info-dma, and -spu-info-proxydma commands.
doc/ChangeLog:
* gdb.texinfo (GDB/MI Miscellaneous Commands): Document -spu-info
commands.
