I have actually made some progress on this serial port card! I looked at how FreeBSD has it configured, tried to map the values to the OpenBSD struct, and actually got something working!
I added the following to pcidevs: vendor PERLE 0x155f Perle vendor COMTROL 0x11fe Comtrol product PERLE R35583 0xb008 Speed8 LE product COMTROL 5002265 0x0805 RocketPort uPCI Octa I added the following to pucdata.c: { { PCI_VENDOR_PERLE, PCI_PRODUCT_PERLE_R35583, 0, 0 }, { 0xffff, 0xffff, 0, 0 }, { { PUC_COM_POW2(0), 0x10, 0x0000 }, { PUC_COM_POW2(0), 0x10, 0x0008 }, { PUC_COM_POW2(1), 0x10, 0x0010 }, { PUC_COM_POW2(1), 0x10, 0x0018 }, { PUC_COM_POW2(2), 0x10, 0x0020 }, { PUC_COM_POW2(2), 0x10, 0x0028 }, { PUC_COM_POW2(3), 0x10, 0x0030 }, { PUC_COM_POW2(3), 0x10, 0x0038 }, }, }, And much to my surprise, it shows up (with some issues) and when i connect 2 of the ports with a null modem adapter, i can cu from one to another! (For now, I’m not too concerned about the RocketPort card) The dmesg looks like this: puc0 at pci0 dev 9 function 0 "Perle Speed8 LE" rev 0x00: ports: 8 com com4 at puc0 port 0 apic 2 int 18: st16650, 32 byte fifo com4: probed fifo depth: 16 bytes com5 at puc0 port 1 apic 2 int 18: st16650, 32 byte fifo com5: probed fifo depth: 16 bytes com6 at puc0 port 2 apic 2 int 18: st16650, 32 byte fifo com6: probed fifo depth: 16 bytes com7 at puc0 port 3 apic 2 int 18: st16650, 32 byte fifo com7: probed fifo depth: 16 bytes puc0: couldn't get subregion for port 4 puc0: couldn't get subregion for port 5 puc0: couldn't get subregion for port 6 puc0: couldn't get subregion for port 7 puc1 at pci0 dev 9 function 1 "Perle Speed8 LE" rev 0x00: ports: 8 com com8 at puc1 port 0 apic 2 int 18: st16650, 32 byte fifo com9 at puc1 port 1 apic 2 int 18: st16650, 32 byte fifo com10 at puc1 port 2 apic 2 int 18: st16650, 32 byte fifo com11 at puc1 port 3 apic 2 int 18: st16650, 32 byte fifo puc1: couldn't get subregion for port 4 puc1: couldn't get subregion for port 5 puc1: couldn't get subregion for port 6 puc1: couldn't get subregion for port 7 "Comtrol RocketPort uPCI Octa" rev 0x01 at pci0 dev 10 function 0 not configured Now some questions: I first listed all 8 ports with PUC_COM_POW2(3) because I think I saw a similar device (a Boca card or something) using it. it worked fine (one of the ports was connected to a different machine an cu could pass text). I then changed the numbers passed in (to 0, 1, 2, 3) just to see if anything changed, and the first and second ports can still talk to each other. What exactly does that value do? Why do the first four ports probe to 16 bytes but not the next four? I read somewhere that this card has two four-port chips, so that why it is recognized as two devices. It’s just strange that some have the probe depth message and some don’t. What is up with the “couldn’t get subregion” message? I did a search and couldn’t find anything about that string on the Internet. This is my first real attempt at development of this type so I am pretty happy about this. I would love for 5.9 to have support for this card. I also have a couple RocketPort cards and I could probably send one to someone if they would want to work on it. Jordon
