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