Look into this line: ssb0: <Broadcom BCM4315 802.11b/g Wireless> mem 0xf4000000-0xf4003fff There we see, device have 0x4000 memory window. Each core required 0x1000. Your code to call required core move PCI window to appropriate 0x1000 block (if core - second, move to 0xf4001000). Maybe we can map full window, and then access to required core without core switching. >> >> regards, >> Weongyo Jeong >> -- Рыбалко Александр Консультант D-Link Украина _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
