Hello, freebsd-hackers I'm trying to add parallel port card support to the puc(4) driver. The chip is an OX12PCI840, which is a PCI chip (in my case it is attached via cardbus bridge).
I have two questions related to it: 1) Will I need additional code in the puc driver itself (revised the code I assumed that it is not needed, as parallel port cards are normally identified - the exception may be the EPP extended register which is in my case not 0x400h above the standard register, but just located in another BAR). 2) I currently experiment with the ppc driver, and I found the problem located in the ppc_detect_port function - writing into the standard parallel IO port (which in my case is located at BAR0 (bar 0x10)) 0xaa and reading it then doesnt give the 0xaa again :( Have anyone ever tried to deal with puc parallel devices or experienced similar problems (probably it related to cardbus bridge?)?
