Not sure if -stable is the right place for this, but I'll give it
a shot; if it's not, then a pointer in the right direction would
be much appreciated.
I'm having a problem with a StarTech PEX2S952 dual-port serial
card.
I believe that it should be supported, as it has this entry in
pucdata.c
[...]
{ 0x1415, 0xc158, 0xffff, 0,
"Oxford Semiconductor OXPCIe952 UARTs",
DEFAULT_RCLK * 0x22,
PUC_PORT_NONSTANDARD, 0x10, 0, -1,
.config_function = puc_config_oxford_pcie
},
[...]
And, while it is recognized at boot -- after adding
device puc
options COM_MULTIPORT
to my kernel, it doesn't seem to be working. The devices '/dev/cuau2'
and '/dev/cuau3' show up, and I can connect to them, but they don't
seem to pass any traffic. If I connect to the serial console of
another machine (one that I know for certain is working), I get
nothing at all.
I suspect (?) that it may not be recognized as the proper card. Boot
and pciconf messages are:
puc0: <Oxford Semiconductor OXPCIe952 UARTs> mem 0xf9dfc000-0xf9dfffff,0xfa000000-0xfa1fffff,0xf9e00000-0xf9ffffff irq 30 at device 0.0 on pci4
puc0@pci0:4:0:0: class=0x070002 card=0xc1581415 chip=0xc1581415 rev=0x00 hdr=0x00
vendor = 'Oxford Semiconductor Ltd'
class = simple comms
subclass = UART
bar [10] = type Memory, range 32, base 0xf9dfc000, size 16384, enabled
bar [14] = type Memory, range 32, base 0xfa000000, size 2097152, enabled
bar [18] = type Memory, range 32, base 0xf9e00000, size 2097152, enabled
The kernel is actually FreeBSD 9.0-BETA1 amd64, which is not quite
'STABLE' yet, but I don't think that this should matter.
Any advice would be much appreciated. The machine is still in
test phase, so I can mess around with it as necessary.
Thanks.
