Seems to work great other than a lock ordering issue wrt page faults. I switched all the lockmgr() locks to sx locks and I get this: lock order reversal 1st 0xc1e09324 rm.mutex_lock (rm.mutex_lock) @ nvidia_os.c:609 2nd 0xc3aec1a0 dev.api_lock (dev.api_lock) @ nvidia_subr.c:741 KDB: stack backtrace: kdb_backtrace(c06323c2,c3aec1a0,c45f41c0,c45f41c0,c45f4386) at kdb_backtrace+0x2e witness_checkorder(c3aec1a0,9,c45f4386,2e5,c04d78a6) at witness_checkorder+0x6b2 _sx_xlock(c3aec1a0,c45f4386,2e5,d76c07bc,c45da851) at _sx_xlock+0x7e nv_lock_api(c3ae5700,0,d9,c3080200,c3080200) at nv_lock_api+0x29 nvidia_dev_mmap(c3080200,f0000000,d76c07dc,1,f0000) at nvidia_dev_mmap+0x31 dev_pager_getpages(c2e807bc,d76c08a4,1,0,d76c0868) at dev_pager_getpages+0xce vm_fault(c274fb90,28a4b000,1,0,c1bb5000) at vm_fault+0x94e trap_pfault(d76c0960,0,28a4b000,d76c0984,28a4b000) at trap_pfault+0xf7 trap(18,10,10,f0000000,c3ae5700) at trap+0x350 calltrap() at calltrap+0x5 --- trap 0xc, eip = 0xc05ff911, esp = 0xd76c09a0, ebp = 0xd76c09b0 --- fubyte(28a4b000,2,c3f54800,d76c09f4,c443b87a) at fubyte+0x1d nv_get_user_phys_address(28a4b000,1,0,c4430639,2000000) at nv_get_user_phys_address+0x30 _nv001233rm(c1a5c400,c3ca4000,c253bc00,c067f098,0) at _nv001233rm+0x92 _nv006271rm(c1d00002,2050200,2,0,0) at _nv006271rm+0x143 _nv006527rm(d76c0c58,4,0,c067f878,1) at _nv006527rm+0x65 _nv006196rm(c485ad20,c3977700,24,d76c0c58,c062bb0a) at _nv006196rm+0x113 rm_ioctl(c485ad20,c3977700,24,d76c0c58,c0284624) at rm_ioctl+0x1d nvidia_handle_ioctl(c3aeb900,c0284624,d76c0c58,3,c1bb5000) at nvidia_handle_ioctl+0x73 nvidia_ctl_ioctl(c3aeb900,c0284624,d76c0c58,3,c1bb5000) at nvidia_ctl_ioctl+0xcc spec_ioctl(d76c0b80,d76c0c2c,c0519f15,d76c0b80,1) at spec_ioctl+0x1ae spec_vnoperate(d76c0b80,1,c06371e4,30e,c06762e0) at spec_vnoperate+0x18 vn_ioctl(c1ffc94c,c0284624,d76c0c58,c198e480,c1bb5000) at vn_ioctl+0x1b5 ioctl(c1bb5000,d76c0d14,c,d76c0d3c,3) at ioctl+0x4f2 syscall(2f,2f,2f,bfbfed4c,0) at syscall+0x272 Xint0x80_syscall() at Xint0x80_syscall+0x1f --- syscall (54, FreeBSD ELF32, ioctl), eip = 0x2826293f, esp = 0xbfbfec8c, ebp = 0xbfbfeca8 --- I was able to get the port going with these changes: <http://green.homeunix.org/~green/nvidia-driver-port.tar.bz2>; -- Brian Fundakowski Feldman \'[ FreeBSD ]''''''''''\ <> green@FreeBSD.org \ The Power to Serve! \ Opinions expressed are my own. \,,,,,,,,,,,,,,,,,,,,,,\
