One rate-limited (0.5 s) sema-xchan line per pass for the X DDX channel:
rrc/uok/upa/uas/put/get/last/ring_pa/entry0 - names the decode-gate state
independently of the shared userdp budget. Diagnostic only, no behaviour
change. params-r1624.txt is the rich r1624 insmod set as a durable
tools/guest-diag file (INSMOD_PARAMS=tools/guest-diag/params-r1624.txt).
Context (c130/c131 with the rich set): the DDX DMA test now PASSES on most
attempts (tracker release decoded + delivered); the remaining gap is the
USERD speculative-latch lifetime (a latch that delivered the test kick is
REJECTED 15 s later with no PUT advance; the next generation then adopts a
stale VRAM block, put=2 get=0, and the retry window closes) plus a later
'Push buffer object allocation failed: 0x51 NV_ERR_NO_MEMORY' (emulated heap
accounting; 1872 MiB free).
