My wireless card is recognised as being a AR5424 by OpenBSD. Unfortunately, it is a non-supported card. After some hacking, I was able to make it work by using some code both from Linux and NetBSD device drivers.
After some initial doubts about licensing issues (I though the Linux code was GPL but at the end I figured out that it is dual-licensed BSD/GPL), I decided to send my patch to the list. Final question is: am I breaking something else? Probably yes since I know nothing about wireless cards... so, this patch works for me but I did not tried it with any other card. Here's the output of pcidump with information about my wireless card: 20:0:0: Atheros AR5424 0x0000: Vendor ID: 168c Product ID: 001c 0x0004: Command: 0007 Status ID: 0010 0x0008: Class: 02 Subclass: 00 Interface: 00 Revision: 01 0x000c: BIST: 00 Header Type: 00 Latency Timer: 00 Cache Line Size: 08 0x0010: BAR mem 64bit addr: 0x00000000f8200000 0x0018: BAR empty (00000000) 0x001c: BAR empty (00000000) 0x0020: BAR empty (00000000) 0x0024: BAR empty (00000000) 0x0028: Cardbus CIS: 00005001 0x002c: Subsystem Vendor ID: 144f Product ID: 7096 0x0030: Expansion ROM Base Address: 00000000 0x0038: 00000000 0x003c: Interrupt Pin: 01 Line: 0b Min Gnt: 00 Max Lat: 00 0x0040: Capability 0x01: Power Management 0x0050: Capability 0x05: Message Signaled Interrupts (MSI) 0x0060: Capability 0x10: PCI Express 0x0090: Capability 0x11: Extended Message Signaled Interrupts (MSI-X) Regards, Luis Index: dev/ic//ar5212.c =================================================================== RCS file: /home/miguel/openbsd-cvsroot//src/sys/dev/ic/ar5212.c,v retrieving revision 1.51 diff -c -p -r1.51 ar5212.c *** dev/ic//ar5212.c 2 Jun 2009 12:39:02 -0000 1.51 --- dev/ic//ar5212.c 22 Jan 2010 22:31:45 -0000 *************** HAL_BOOL ar5k_ar5212_nic_wakeup(struct *** 30,35 **** --- 30,36 ---- u_int16_t ar5k_ar5212_radio_revision(struct ath_hal *, HAL_CHIP);
