/* This include file defines the interface between the main part
|
|
|
|
|
of the debugger, and the part which is target-specific, or
|
|
|
|
|
specific to the communications interface between us and the
|
|
|
|
|
target.

|
A TARGET is an interface between the debugger and a particular
|
|
|
|
|
kind of file or process. Targets can be STACKED in STRATA,
|
1999-04-16 03:35:26 +02:00
|
|
|
|
so that more than one target can potentially respond to a request.
|
|
|
|
|
In particular, memory accesses will walk down the stack of targets
|
|
|
|
|
until they find a target that is interested in handling that particular
|
|
|
|
|
address. STRATA are artificial boundaries on the stack, within
|
|
|
|
|
which particular kinds of targets live. Strata exist so that
|
|
|
|
|
people don't get confused by pushing e.g. a process target and then
|
|
|
|
|
a file target, and wondering why they can't see the current values
|
|
|
|
|
of variables any more (the file target is handling them and they
|
|
|
|
|
never get to the process target). So when you push a file target,
|
|
|
|
|
it goes into the file stratum, which is always below the process
|
|
|
|
|
stratum. */

* target.h (#include "memattr.h"): Added.
(target_ops.to_xfer_memory): Add attrib argument.
* wince.c (_initialize_inftarg): Removed call to set_dcache_state.
* 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.

0 means that we can't handle this. If errno has been set, it is the

beyond this length, but no promises.

negative (call its absolute value N) means that we cannot

NOTE: cagney/2003-10-17: The current interface can lead to

|
|
fragmented transfers. Lower target levels should not implement
|
|
|
|
|
hacks, such as enlarging the transfer, in an attempt to
|
|
|
|
|
compensate for this. Instead, the target stack should be
|
|
|
|
|
extended so that it implements supply/collect methods and a
|
|
|
|
|
look-aside object cache. With that available, the lowest
|
|
|
|
|
target can safely and freely "push" data up the stack.
|
|
|
|
|
|
|
|
|
|
See target_read and target_write for more information. One,
|
|
