  • Tools/Gdb Server

    v28 v29  
    202202  * 0x10 (MIPS32_DEBUG_DATA - print CPU load/store)
    203203
     204 * If supported by the cache, the gdb server can enable the display of debugging information form the cache during the simulation. This mask can be set via the gdb server with the following command ({{{val}}} is the new value of the mask):
     205{{{
     206(gdb) monitor cachedebug val
     207}}}
     208 At the moment, only the cc_vcache models support the debug mask and defines the following values:
     209  * 0x1 (dcache FSM debug)
     210  * 0x2 (icache FSM debug)
     211  * 0x4 (cleanup FSM debug)
     212
    204213 * Cycle breakpoints can be used to instruct the `GdbServer` to stop the simulation at a given cycle number. This enables taking advantage of the fact that SoCLib simulations always yield the same result when executed multiple times. This allows starting a simulation again with a cycle break point to examine the simulator state just before a chosen point is reached or particular event happens. Cycle counts are reported when using the call trace feature for instance. The `SOCLIB_GDB_CYCLEBP` environment variable must be set to the breaking cycle number to define a cycle break point.
