It seems that FreeBSD's > implementation uses the %gs register, which NVidia also wants to use. Nvidia's driver is using %gs to implement its own type of TLS since FreeBSD doesn't provide TLS. Once FreeBSD provides real TLS, then the Nvidia driver can use that which will result in both the driver and the threading code sharing %gs nicely. (Since %gs will be used to implement TLS). -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
