Summary: parallel port access is slow due to high cpu usage (eprom burner) Product: Wine Version: 0.9 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wine-binary AssignedTo: wine-bugs@winehq.org ReportedBy: pkk@spth.de
Whe I burn EPROMs with the willem eprom burner (software at http://www.willem.org/ZIP/epr097ja.zip) wine needs a lot of cpu power. Parallel port access speed scales with CPU speed.
I run wine as root and have added the following registry keys:
[HKEY_USERS\S-1-5-4\Software\Wine\VDM]
[HKEY_USERS\S-1-5-4\Software\Wine\VDM\Ports] "read"="0x278-0x27f,0x378-0x37f" "write"="0x278-0x27f,0x378-0x37f"
[HKEY_USERS\S-1-5-4\Software\Wine\VDM\ppdev] "378"="/dev/parport0"
