Summary: Wine OSS driver sometimes uses 100% CPU.
Product: Wine
Version: 0.9
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED
Severity: major
Priority: P2
Component: wine-multimedia
AssignedTo: wine-bugs at winehq.org
ReportedBy: markknecht at gmail.com
When running Windows VSTs in a hosting app like Savihost sometimes Wine uses
100% CPU according to top:
mkdir SAVITEST
cd SAVITEST
wget http://www.hermannseib.com/programs/savihost.zip
unzip savihost.zip
wget http://www.greenoak.com/crystal/dl/Crystal.zip
unzip Crystal.zip
cp savihost.exe Crystal.exe
Now, run Savihost for the Crystal dll:
mark at lightning ~/SAVITEST $ wine ./Crystal.exe
With Wine set to use the OSS driver (the current default) Wine uses 100% CPU.
(Approcimately 15% usr, 85% sys on my AMD64 3000+ machine.
We have seen this problem on multiple machines (ia-32 and AMD64) and using many
VSTs other than Crystal.dll.
I'm entering this as 'major' as 100% CPU usage seems really bad to us.
