hi-
i was looking into adding support for the Dell 2650's embedded
management processor's virtual 16550 UART. it turns out that this
device shares a PCI_ID_REG value with a RAID controller on other
systems and you have to use PCI_SUBSYS_ID_REG to tell them apart.
i.e.:
vendor device subvend subdevice what it is
0x1028 0x0008 0x1028 0x00cf Dell PERC 3/Di
0x1028 0x0008 0x1028 0x0008 Dell RAC Serial PPP Link
exactly how is this kind of info supposed to be added to src/sys/dev/pcidevs?
is the device and subdevice info supposed to be all mixed together?
is there a naming convention for sub-info i should follow?
looking at src/sys/dev/pcidevs, we currently have:
/* Dell Computer products */
product DELL PERC_2SI 0x0001 PERC 2/Si
product DELL PERC_3DI 0x0002 PERC 3/Di
product DELL PERC_3SI 0x0003 PERC 3/Si
product DELL PERC_3SI_2 0x0004 PERC 3/Si

product DELL PERC_3DI_3 0x000a PERC 3/Di
product DELL PERC_3SI 0x0003 PERC 3/Si
product DELL PERC_3DI_2_SUB 0x00cf PERC 3/Di
product DELL PERC_3SI_2_SUB 0x00d0 PERC 3/Si
product DELL PERC_3DI_SUB2 0x00d1 PERC 3/Di
product DELL PERC_3DI_SUB3 0x00d9 PERC 3/Di
product DELL PERC_3DI_3_SUB 0x0106 PERC 3/Di
product DELL PERC_3DI_3_SUB2 0x011b PERC 3/Di
