From: "Bill Lortz" <blortz@...> To: <bug-followup@...>, <david@...> Cc: Subject: Re: kern/134878: [puc] [patch] Add support for Oxford OXPCIe954 and OXPCIe958 PCI Express chips Date: Sun, 8 Nov 2009 11:02:46 -0800 This is a multi-part message in MIME format. ------=_NextPart_000_01B3_01CA6063.01402410 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit I have the FreeTech PCI-e mini card with 1 serial and 1 parallel port (part #PEX1S1PMINI) that claims to use the Oxford OXPCIe952 chip. The computer is a FITPC2 (Intel Atom-based computer). After applying the puc patch, enabling puc in the kernel and re-compiling, the card is recognized, but no driver was assigned. I ran a pciconf -lv to list the pci devices and found the chip id's didn't match anything in the patched driver. So, I changed an entry in the patched code for the 952 chip from "0x1415, 0x15d" to "0x1415, 0xc11b" so that it matched the output from the pciconf. Since I was only interested in the serial function, I didn't try to patch for the parallel port function. After recompiling the kernel it worked and assigned a device driver to the UART. I wasn't comfortable in my patch to add a new table entry, so that is why I changed an existing entry. I suspect the proper patch would be to add a new table entry. I've included the output from my "pciconf" that shows the pci card and chip ids for both the serial and parallel ports. Notice that it assigned a device puc0 to the UART. none3@pci0:3:0:0: class=0x070102 card=0xc1181415 chip=0xc1181415 rev=0x00 hdr=0x00 vendor = 'Oxford Semiconductor Ltd' class = simple comms subclass = parallel port puc0@pci0:3:0:3: class=0x070002 card=0xc11b1415 chip=0xc11b1415 rev=0x00 hdr=0x00 vendor = 'Oxford Semiconductor Ltd' class = simple comms subclass = UART I'm very new to FreeBSD and am not sure if I approached notification of my findings in the correct way by submitting this followup. In any case, I hope it is helpful since I assume it is hard for the developers to test on every combination of computer and card. If a new patch is released, I'd be happy to test it out.
