BUGLE-STATS_NV(7) Bugle user manual BUGLE-STATS_NV(7)NAMEbugle-stats_nv - gather performance data from NVPerfSDK
SYNOPSIS
filterset stats_nv
{
flush "yes"
}
DESCRIPTION
The stats_nv filter-set extracts data from certain NVIDIA GPUs using
NVPerfSDK. This filter-set is only built if the appropriate header file
is present at compile time, and also requires a suitably configured
driver and GPU (refer to the NVPerfSDK[1] documentation).
The possible statistics can be seen in the example statistics file
(doc/examples/statistics in the bugle source distribution). It is
important to read the NVPerfSDK documentation to understand what the
different types of statistics are, what they mean, and the limitations
of the hardware interface.
OPTIONS
flush
If set, a glFinish(3) will be issued immediately prior to sampling
the counters. This guarantees that events will be accounted to the
correct frame, but will cause pipeline stalls.
BUGS
Because NVPerfSDK operates across OpenGL contexts, it will count events
from outside the debugged application. In particular, using bugle-
showstats(7) to view the results will alter the statistics.
