From 18c6813f2c788b603dab363b9138d65d24252167 Mon Sep 17 00:00:00 2001 From: tzafrir Date: Wed, 27 May 2009 10:01:24 +0000 Subject: Big dump of newer xpp code. For finer details and separate commits, you are advised to look into the commit log of dahdi-{linux,tools}. xpp.r7150 * 116x Astribanks: - Support for the TwinStar capability and for FXO and (BRI|PRI) on same device. - New control protocol ("MPP"). - astribank_hextool - a low-level firmware loading tool instead of fpga_load . - astribank_tool - Other MPP activities . - Can still reset (but just that) through older protocol. - astribank_hexload is required for loading FPGA firmware for USB_FW.hex rev > 6885. - USB_FW rev. 7071 . - More modular FPGA firmware (1161 only). - FPGA_1161.hex rev. 7131. PIC_TYPE_* rev. 7107. - software-settings of some capabilities with astribank_allow . * XPP: - init_card_* script are less verbose. - Reduced rate of "Is a DAHDI sync master" message. - Replace member bus_id with dev_name() and set_dev_name() for building with 2.6.30. - Conditionally remove 'owner' property of procfs was dropped in 2.6.30. - astribank_hook now enabled by default. - Has an optional hook for TwinStar. * BRI: - hardhdlc support: The bri_dchan patch is no longer needed. - If bri_dchan patch applied: old code is used, and "dchan" is used. - If not: new code and "hardhdlc" is used. - zapconf will generate the right configuration, depending on the new sysfs driver attribute bri_hardhdlc, but default to "dchan" as before if not explicitly told. - Bugfix: explicitly turn off leds on startup. * FXS: - Initialization and calibration fixes. - Notify the user just one about wrong VMWI config * Dahdi-perl: - Fix detection of empty slots in wctdm. - Fix working with ethmf's extra file in /proc/zaptel - Improved detection of Rhino cards. - dahdi_genconf's generated text better explains files are generated. - /etc/xpp_order - allow specifiying an explicit order for Astribanks to register with Zaptel. - Dahdi::Xpp::Mpp - A wrapper around astribank_tool . * dahdi.init: - A separate waitfor_xpds script. May now have a wait-loop in some cases. - xpp_sync needs to only be called after dahdi_cfg . (for the PRI module). git-svn-id: http://svn.digium.com/svn/zaptel/branches/1.4@4641 5390a7c7-147a-4af0-8ec9-7488f05a26cb --- kernel/xpp/utils/astribank_allow.c | 378 +++++++++++++++++++++++++++++++++++++ 1 file changed, 378 insertions(+) create mode 100644 kernel/xpp/utils/astribank_allow.c (limited to 'kernel/xpp/utils/astribank_allow.c') diff --git a/kernel/xpp/utils/astribank_allow.c b/kernel/xpp/utils/astribank_allow.c new file mode 100644 index 0000000..ec60d4a --- /dev/null +++ b/kernel/xpp/utils/astribank_allow.c @@ -0,0 +1,378 @@ +/* + * Written by Oron Peled and + * Alex Landau + * Copyright (C) 2008, Xorcom + * + * All rights reserved. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
