Mike Dunn [Wed, 21 Apr 2010 17:40:51 +0000 (13:40 -0400)]
xscale: add support for length arg to wp command

This patch adds support for the length argument to the xscale implementation of
the wp command.  Per discussion with David, the length argument specifies the
range of addresses over which a memory access should generate a debug exception.
This patch utilizes the "mask" feature of the xscale debug hardware to implement
the correct functionality of the length argument.  Some limitations imposed by
the hardware are:

   - The length must be a power of two, with a minumum of 4.
   - Two data breakpoint registers are available, allowing for two watchpoints.
     However, if the length of a watchpoint is greater than four, both registers
     are used (the second for a mask value), limiting the number of watchpoints
     to one.

This patch also removes a useless call to xscale_get_reg(dbcon) in
xscale_set_watchpoint() (value had already been read from the register cache,
and the same previously read value is then modified and written back).

I have been using and testing this patch for a couple days.

Questions, corrections, criticisms of course gratefully received.

14 years agoxscale: fix analyze_trace for trace data collected in wrap mode
Mike Dunn [Tue, 13 Apr 2010 17:34:52 +0000 (13:34 -0400)]
xscale: fix analyze_trace for trace data collected in wrap mode

This patch fixes the xscale_analyze_trace() function.  This function was
defective for a trace collected in 'fill' mode (hiccups with repeated
instructions) and completely broken when buffer overflowed in 'wrap' mode.  The
reason for the latter case is that the checkpoint registers were interpreted
incorrectly when two checkpoints are present in the trace (which will be true in
'wrap' mode once the buffer fills).  In this case, checkpoint1 register will
contain the older entry, and checkpoint0 the newer.  The original code assumed
the opposite.  I eventually gave up trying to understand all the logic of the
function, and rewrote it.  I think it's much cleaner and understandable now.  I
have been using and testing this for a few weeks now.  I'm confident it hasn't
regressed in any way.

Also added capability to handle (as best as possible) the case where an
instruction can not be read from the loaded trace image; e.g., partial image.
This was a 'TODO' comment in the original xscale_analyze_trace().

Outside of xcsale_analyze_trace(), these (related) changes were made:

- Remove pc_ok and current_pc elements from struct xscale_trace.  These elements
  and associated logic are useless clutter because the very first entry placed
  in the trace buffer is always an indirect jump to the address at which
  execution resumed.  This type of trace entry includes the literal address in
  the trace buffer, so the initial address of the trace is immediately
  determined from the trace buffer contents and does not need to be recorded
  when trace is enabled.

- Added num_checkpoints to struct xscale_trace_data, which is necessary in order
  to correctly interpret the checkpoint register contents.

- In xscale_read_trace()
  - Fix potential array out-of-bounds condition.
  - Eliminate partial address entries when parsing trace (can occur in wrap mode).
  - Count and record number of checkpoints in trace.

- Added small, inlined utility function xscale_display_instruction() to help
  make the code more concise and clear.

TODO:
 - Save processor state (arm or thumb) in struct xscale_trace when trace is
   enabled so that trace can be analyzed correctly (currently assumes arm mode).
 - Add element to struct xscale_trace that records (when trace is enabled)
   whether vector table is relocated high (to 0xffff0000) or not, so that a
   branch to an exception vector is traced correctly (curently assumes vectors
   at 0x0).

14 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.

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

In the ft2232 driver, initialization for many layouts punts to a routine

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
specific to the "usbjtag" layout.

Split and document out the generic parts of usbjtag_init(), and make
the rest of those layouts have layout-specific init methods.  Also,
rename usbjtag_reset() ... that also was not specific to the "usbjtag"
layout, and thus contributed to the previous code structure confusion.

By a bit of code inspection it seems like all of these
instances of jtag_get_end_state() can be unambigously
replaced by constants.

Fix underlying problem with xscale icache and dcache commands

Fix problem with the xscale icache and dcache commands.  Both commands were
enabling or disabling the mmu, not the caches

I didn't look any further after my earlier patch fixed the trivial problem
with command argument parsing.  Turns out the underlying code was broken.

The resolution is straightforward when you look at the arguments to
xscale_enable_mmu_caches() and xscale_disable_mmu_caches().  I finally
took a deeper look after dumping the cp15 control register (XSCALE_CTRL)
and seeing that the cache bits weren't changing, but the mmu bit was
(which caused all manner of grief, as you can imagine).  This has been
tested and works OK now.

ADI_v5 - it's not always an "SWJ-DP"

So don't use the name "swjdp" for all DAPs; rename to
plain old "dap", which *is* always correct.

remove more duplication

Not sure how the original "move code to adi_v5_swd.c" patch left
some code in the "arm_adi_v5.c" file, but a recent patch was only
a partial fix -- it didn't remove all the duplication.
