From e75919bc9e1cb1b5f8f69b5a5aabed9b3a1a53d9 Mon Sep 17 00:00:00 2001 From: Josh Blum Date: Sun, 1 May 2011 15:42:32 -0700 Subject: usrp2: added the concept of device locking to usrp2/nseries devices Each iface instance can lock itself to a particular device. When the device is locked, it cannot be discovered through find. Locking works by having a lock thread periodically update a register in the firmware that says when the device was last locked. The find routine can determine if a device is locked by checking the difference between the current time and this register. --- host/lib/usrp/usrp2/usrp2_regs.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'host/lib/usrp/usrp2/usrp2_regs.cpp') diff --git a/host/lib/usrp/usrp2/usrp2_regs.cpp b/host/lib/usrp/usrp2/usrp2_regs.cpp index 57ae36857..240bc3bab 100644 --- a/host/lib/usrp/usrp2/usrp2_regs.cpp +++ b/host/lib/usrp/usrp2/usrp2_regs.cpp @@ -56,7 +56,7 @@ int sr_addr(int sr) { return SETTING_REGS_BASE + (4 * sr); } -usrp2_regs_t usrp2_get_regs(bool) { +usrp2_regs_t usrp2_get_regs(void) { usrp2_regs_t x; x.misc_ctrl_clock = sr_addr(0); x.misc_ctrl_serdes = sr_addr(1); -- cgit v1.2.3
