* xscale: add support for length arg to wp commandMike Dunn2010-04-241-8/+51
| | | | | | | | | | | | | | | | | | | | | | | 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.

* stm32x: allow flash probe on a running targetAndreas Fritiofson2010-04-201-6/+0
| | | | | | | | | | | | | | | If the flash has not yet been probed and GDB connects while the target is running, the flash probe triggered by GDB's memory map read will fail. In that case the returned memory map will be empty, causing a subsequent load from within GDB to fail. There's not much you can do from GDB to recover, other than a restart; a 'mon reset init' and manual 'mon flash probe' won't help since GDB has already made up its mind about the memory map. It seems there's no reason to require the target to be halted when probing the flash. Remove the check to let a valid memory map be provided to GDB even when connecting to a running target.

* xscale: fix analyze_trace for trace data collected in wrap modeMike Dunn2010-04-152-216/+243
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).
