10 years agoxscale: fix trace buffer functionality when resuming from a breakpoint
Mike Dunn [Sun, 28 Mar 2010 19:48:32 +0000 (15:48 -0400)]
xscale: fix trace buffer functionality when resuming from a breakpoint

Problem: halt at a breakpoint, enable trace buffer ('xscale trace_buffer enable
fill'), then resume.  Wait for debug exception when trace buffer fills (if not
sooner due to another breakpoint, vector catch, etc).  Instead, never halts.
When halted explicitly from OpenOCD and trace buffer dumped, it contains only
one entry; a branch to the address of the original breakpoint.  If the above
steps are repeated, except that the breakpoint is removed before resuming, the
trace buffer fills and the debug exception is generated, as expected.

Cause: related to how a breakpoint is stepped over on resume.  The breakpoint is
temporarily removed, and a hardware breakpoint is set on the next instruction
that will execute.  xscale_debug_entry() is called when that breakpoint hits.
This function checks if the trace buffer is enabled, and if so reads the trace
buffer from the target and then disables the trace (unless multiple trace
buffers are specified by the user when trace is enabled).  Thus you only trace
one instruction before it is disabled.

Solution: kind of a hack on top of a hack, but it's simple.  Anything better
would involve some refactoring.  This has been tested and trace now works as
intended, except that the very first instruction is not part of the trace when
resuming from a breakpoint.

TODO: still many issues with trace: doesn't work during single-stepping (trace
buffer is flushed each step), 'xscale analyze_trace' works only marginally for
a trace captured in 'fill' mode, and not at all for a trace captured in 'wrap'
mode.

fix software breakpoints on xscale

This patch fixes xscale software breakpoints by cleaning the dcache and
invalidating the icache after the bkpt instruction is inserted or removed.  The
icache operation is necessary in order to flush the fetch buffers, even if the
icache is disabled (see section 4.2.7 of the xscale core developer's manual).
The dcache is presumed to be enabled; no harm done if not.  The dcache is also
invalidated after cleaning in order to safeguard against a future load of
invalid data, in the event that cache_clean_address points to memory that is
valid and in use.

Also corrected a confusing typo I noticed in a comment.

TODO (or not TODO...?): the xscale's 2K "mini dcache" is not cleaned.  This
cache is not used unless the 'X' bit in the page table entry is set.  This is a
proprietary xscale extension to the ARM architecture.  If a target's OS or
executive makes use of this for memory regions holding code, the breakpoint
problem will persist.  Flushing the mini dcache requires that 2K of valid
cacheable memory (mapped with 'X' bit set) be designated by the user for this
purpose.  The debug handler that gets downloaded to the target will also need to

That routine is  a mess  built around a "what type layout am I" core.
That's a bad design ... in this case, especially so, since it bypasses
the layout-specific dispatch which was just done, and obfuscates the
initialization which is at least somewhat generic, instead of being

rename usbjtag_reset() ... that also was not specific to the "usbjtag"

split "interface" commands from "jtag" ones

We'll need to be able to work with debug adapter interfaces (drivers)
even when they're not used for JTAG ... for example, while there are
multi-transport drivers which support JTAG *and* several other
transports (or just one more, like SWD) there are also adapters
with more limited goals (and no JTAG support at all).

Start decoupling the two concepts ("debug adapter driver", "jtag")
by having two command groups, which initialize separately.

This will help us support OpenOCD sessions using only non-JTAG
transports, in which JTAG commands should not be registered.
Update docs to mention that the JTAG, SVF, and XSVF commands
won't work without a JTAG transport.

Note that at least commands working with SRST are still inappropriately
coupled  to JTAG ... inappropriate because (a) SRST is not part of the
JTAG standard, for all that many platforms (like ARM) expect it; and also
(b) because they're used with non-JTAG debug and programming interfaces,
too.  They should perhaps become generic "interface" operations at some
point.  (Similarly with the clock rate to be used by a given adapter.)

adapters are discrete widgets; some are integrated onto boards.  If
we only talk about "dongles" we rule out many valid setups, and help
confuse some users (who may be using Dongle-free environments).

Also start bringing out the point that JTAG isn't the only transport
protocol, even though OpenOCD historically presumes "all is JTAG".
