Hi. I have a Perle Speed/LE-8 card that's poorly supported (cough) by the vendor. The design seems to be plain-vanilla enough: it uses Oxford 9501 and 9511 chips. $ lspci -v -n -s 04:07 04:07.0 0700: 155f:b008 (prog-if 06 [16950]) Subsystem: 1415:9501 Flags: medium devsel, IRQ 21 I/O ports at ec00 [size=32] Memory at fbfff000 (32-bit, non-prefetchable) [size=4K] I/O ports at e880 [size=32] Memory at fbffe000 (32-bit, non-prefetchable) [size=4K] Capabilities: [40] Power Management version 1 Kernel driver in use: perle-serial Kernel modules: perle-serial 04:07.1 0680: 155f:b008 Subsystem: 1415:9511 Flags: medium devsel, IRQ 21 I/O ports at e800 [size=32] Memory at fbffd000 (32-bit, non-prefetchable) [size=4K] I/O ports at e480 [size=32] Memory at fbffc000 (32-bit, non-prefetchable) [size=4K] Capabilities: [40] Power Management version 1 Kernel driver in use: perle-serial Kernel modules: perle-serial $ There's nothing funky about this card except that one of the lines is either DTR or RTS if I've understood the scarce documentation. Anyway, I was wondering what's involved in getting the drivers/tty/serial/8250_pci.c to support this?
