Vortex 2.1 opae runtime issue #127

Open Geunyoung00 opened 5 months ago

Geunyoung00 commented 5 months ago

When I run Quick demo with opae driver, there are meaningless performance prints. it seems to take place only in opae driver.

I found the "PERF: ~~" is printed by the public function "int ready_wait()" in runtime/opae/vortex.cpp. There are many functions calling "ready_wait()" (eg, upload, download ..) So the "PERF ~~" keep printing. As a temporary measure, I just commented the profilling_end() in the "int read_wait()" and added another ready_wait_blah which is not commented profilling_end(). And then changed "device->ready_wait(time_out)" to the new ready_wait_blah in "vx_ready_wait()" function.

I think this is not a proper way, So I upload here that somebody can modify it.

And the api.fpgaProperiesGetLocalMemorySize error still exist in vortex2.1. I cannot understand this function because it doesn't looks to affect to running.

The --driver=opae prints are really annoying indeed. Thank you for posting the workaround. I think they haven't changed this yet.
