Yeah, CONFIG_SSB_MIPS should depend on the MIPS CPU. Which kconfig option do you suggest to make a "depend" on? > drivers/ssb/driver_pci/pcicore.c refers to SSB_PCICORE_SBTOPCI1_CFG1 > that is not defined anywhere in the kernel. Yeah, could be a typo. I'll have a look at it. > I could send you huge logs, but I think it's already a clear sign that > you didn't compile-test the current tree with CONFIG_SSB_DRIVER_MIPS > enabled. Things are better if it is disabled. It is tested. But obviously on MIPS platform. > In case you haven't seen those warnings: > > /home/proski/src/linux-2.6/drivers/net/wireless/d80211/bcm43xx/bcm43xx_main.c:843: > warning: 'bcm43xx_wireless_core_mark_inactive' defined but not used > /home/proski/src/linux-2.6/drivers/net/wireless/d80211/bcm43xx/bcm43xx_main.c:3032: > warning: 'bcm43xx_bluetooth_coext_enable' defined but not used I am very well aware of these warnings, as they mark unimplemented features. > I could compile the code, and it even loaded as a module, but the kernel > oopsed once I brought wlan0 up by ifconfig. > > bcm43xx_d80211: Adding Interface type 2 > bcm43xx_d80211: Found PHY: Version 4, Type 2, Revision 8 > bcm43xx_d80211: Found Radio: Manuf 0x17F, Version 0x2050, Revision 2 > bcm43xx_d80211: Loading firmware version 351.126 (2006-07-29 05:54:02) > bcm43xx_d80211: Radio turned on > bcm43xx_d80211: FIXME: Possibly broken code in bcm43xx_phy_initg() at > /home/proski/src/linux-2.6/drivers/net/wireless/d80211/bcm43xx/bcm43xx_phy.c:1650 > bcm43xx_d80211: Chip initialized > Unable to handle kernel NULL pointer dereference at 0000000000000000 RIP: > [<ffffffff8021eee6>] dma_alloc_coherent+0x52/0x23f > PGD 50d1067 PUD 5201067 PMD 0 > Oops: 0000 [1] SMP > CPU 1 > Modules linked in: bcm43xx_d80211 ssb > Pid: 2623, comm: ifconfig Not tainted 2.6.20-rc3 #5 > RIP: 0010:[<ffffffff8021eee6>] [<ffffffff8021eee6>] > dma_alloc_coherent+0x52/0x23f > RSP: 0018:ffff810005127bd8 EFLAGS: 00010206 > RAX: 0000000000000000 RBX: 0000000000003500 RCX: 00000000000010d4 > RDX: 00000000ffffffff RSI: 0000000000001000 RDI: ffff81000196c3a8 > RBP: 00000000000010d0 R08: ffff81001f6d1600 R09: 0000000000000004 > R10: 0000000000000001 R11: ffff810001122c60 R12: 0000000000001000 > R13: ffff810001b96000 R14: ffff81000196c3a8 R15: 00000000ffffffff > FS: 00002b411b2133b0(0000) GS:ffff810001827440(0000) knlGS:0000000000000000 > CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b > CR2: 0000000000000000 CR3: 0000000015fdf000 CR4: 00000000000006e0 > Process ifconfig (pid: 2623, threadinfo ffff810005126000, task > ffff81001f58d180) > Stack: ffff81001ee6a3c0 ffff81001ee6a3e8 ffff810001b96000 0000000000003500 > ffff81001ee6a3c0 0000000000000080 ffff810001b96000 0000000000000000 > 0000000000000000 ffffffff88019966 0000000000000005 0000000100000036 > Call Trace: > [<ffffffff88019966>] :bcm43xx_d80211:bcm43xx_setup_dmaring+0x1a7/0x460 > [<ffffffff88019ea3>] :bcm43xx_d80211:bcm43xx_dma_init+0xc0/0x290 > [<ffffffff88008131>] :bcm43xx_d80211:bcm43xx_wireless_core_init+0x78f/0x9f1 > [<ffffffff8022885e>] mntput_no_expire+0x19/0x77 > [<ffffffff8020a3c3>] do_page_fault+0x40b/0x74a > [<ffffffff88009f4e>] :bcm43xx_d80211:bcm43xx_add_interface+0x67/0xeb > [<ffffffff804378d2>] ieee80211_open+0x1c6/0x2c5 > [<ffffffff803fd3ec>] dev_open+0x2f/0x6e > [<ffffffff803fbcd5>] dev_change_flags+0x5a/0x119 > [<ffffffff80423bab>] devinet_ioctl+0x235/0x59c > [<ffffffff803f4bef>] sock_ioctl+0x1c8/0x1e5 > [<ffffffff8023b862>] do_ioctl+0x21/0x6b > [<ffffffff8022b614>] vfs_ioctl+0x25c/0x275 > [<ffffffff8024559b>] sys_ioctl+0x3c/0x5c > [<ffffffff802548ee>] system_call+0x7e/0x83 > > > Code: 4c 23 38 49 39 d7 0f 46 e9 49 8d 44 24 ff 83 ca ff 49 89 c5 > RIP [<ffffffff8021eee6>] dma_alloc_coherent+0x52/0x23f > RSP <ffff810005127bd8> > CR2: 0000000000000000 Hm, not sure why this oopses.
