/* This file was derived from remote-eb.c, which did a similar job, but for

an AMD-29K running EBMON. That file was in turn derived from remote.c

as mentioned in the following comment (left in for comic relief):
|
|
|
|

1999-07-07 22:19:36 +02:00
|
|
|
"This is like remote.c but is for a different situation--
|
1999-04-16 03:35:26 +02:00
|
|
|
having a PC running os9000 hook up with a unix machine with
|
|
|
|
a serial line, and running ctty com2 on the PC. os9000 has a debug
|
|
|
|
monitor called ROMBUG running. Not to mention that the PC
|
|
|
|
has PC/NFS, so it can access the same executables that gdb can,
|
|
|
|
over the net in real time."
|
|
|
|
|
|
|
|
In reality, this module talks to a debug monitor called 'ROMBUG', which
|
|
|
|
We communicate with ROMBUG via a direct serial line, the network version
|
|
|
|
of ROMBUG is not available yet.

wait for the prompt, because the terminal is being handed over

to the inferior. However, the next thing which happens after that

is a rombug_wait which does wait for the prompt.

* dcache.h (set_dcache_state): Removed declaration.
* dcache.c (set_dcache_state): Removed definition
* dcache.c: Update module comment, as dcache is now enabled and
disabled with memory region attributes instead of by the global
variable "remotecache". Add comment describing the interaction
between dcache and memory region attributes.
(dcache_xfer_memory): Add comment describing benefits of moving
cache writeback to a higher level.
(dcache_struct): Removed cache_has_stuff field. This was used to
record whether the cache had been accessed in order to invalidate
it when it was disabled. However, this is not needed because the
cache is write through and the code that enables, disables, and
deletes memory regions invalidate the cache. Add comment which
suggests that we could be more selective and only invalidate those
cache lines containing data from those memory regions.
(dcache_invalidate): Updated.
(dcache_xfer_memory): Updated.
(dcache_alloc): Don't abort() if dcache_enabled_p is clear.
(dcache_xfer_memory): Removed code that called do_xfer_memory() to
perform a uncached transfer if dcache_enabled_p was clear. This
function is now only called if caching is enabled for the memory
region.
(dcache_info): Always print cache info.
* target.c (do_xfer_memory): Add attrib argument.
(target_xfer_memory, target_xfer_memory_partial): Break transfer
into chunks defined by memory regions, pass region attributes to
do_xfer_memory().
* dcache.c (dcache_read_line, dcache_write_line): Likewise.
* Makefile.in (SFILES): Add memattr.c.
(COMMON_OBS): Add memattr.o.
(dcache.o): Add target.h to dependencies.
* memattr.c: New file.
* memattr.h: Likewise.
