| 1 # TI's original version of the pf_TaskEntry() function in the guts of GPF | |
| 2 # does this number once all GPF tasks have entered their main loop: | |
| 3 # | |
| 4 # TraceMask[0] = 0; | |
| 5 # | |
| 6 # The effect of this line is that "system" trace output gets disabled; | |
| 7 # in particular, "system primitive" requests like querying for existing | |
| 8 # TRACECLASS of various entities or for the GPF version elicit no response | |
| 9 # whatsoever until one sends a TRACECLASS setting sysprim which restores | |
| 10 # the TC_SYSTEM bit in TraceMask[0]. | |
| 11 # | |
| 12 # In FreeCalypso we consider this clearing of TraceMask[0] to be either | |
| 13 # a bug or a misfeature, and we would like to change it. In the case of | |
| 14 # the GPF code in question, we do have a copy of frame.c source (the module | |
| 15 # where the offending pf_TaskEntry() function is implemented) which we believe | |
| 16 # is the same code as what's in the TCS211 version of GPF, but TCS211 is not | |
| 17 # set up to recompile any part of GPF from source, and there are other modules | |
| 18 # in the same frame_na7_db_ir.lib for which we don't have the original source | |
| 19 # (os_*), hence it is easier to do a binary lib patch. | |
| 20 # | |
| 21 # The present patch is a binary form of: | |
| 22 # | |
| 23 # -TraceMask[0] = 0; | |
| 24 # +TraceMask[0] = TC_SYSTEM; | |
