2013-01-02target: Add support for IQ swap when requiredSylvain Munaut1-2/+5
Operation in GSM850 band requires IQ swap because of the offset PLL used in the TRF causing spectrum reversal. Thanks to Dieter Spaar for noticing the issue and the original patch Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2012-02-12firmware: add missing includesSteve Markgraf1-0/+1
This fixes all 'implicit-function-declaration'-warnings. Signed-off-by: Steve Markgraf <steve@steve-m.de>
2012-01-28target/rf: Make the trf6151_set_arfcn use ARFCN_UPLINK flag to select UL/DLSylvain Munaut1-1/+1
This way we can independentely control what frequency we want and wheter we want to TX or RX. This allow TX on DL band and RX on UL band. This also means all call to tx_window setup now need to properly set the ARFCN_UPLINK flag ! Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2011-04-26src: use new libosmogsm and include/osmocom/[gsm|core] path to headersPablo Neira Ayuso1-2/+2
This patch changes include paths to get osmocom-bb working with the current libosmocore tree. Among all these renames, you can notice several tweaks that I added on purpose, and that require some explanation, they are: * hexdump() in osmocon.c and osmoload.c has been renamed to avoid clashing with hexdump() defined in libosmocore. * gsmmap now depends on libosmogsm. Actually I had to cleanup Makefile.am because I was experiencing weird linking problems, probably due to a bug in the autotools. With the change included in this patch, I got it compiled and linked here correctly. This patch has been tested with the phone Motorola C123 and the following images files: * firmware/board/compal_e88/hello_world.compalram.bin * firmware/board/compal_e88/layer1.compalram.bin Using the osmocon, bcch_scan and mobile tools.

2010-09-26target/layer1: Implement host-driven Tx power controlSylvain Munaut1-1/+1
It's up to L23 to change the parameters using the appropriate L1CTL call. This is a mix between Harald's version and Dieter's version of the TX control code. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2010-09-17fw/layer1: Add common TPU win setup/cleanup codeSylvain Munaut1-1/+1
Instead of each primitive doing it independently, if there is a TPU scenario in one of the item, we do a common setup with the base tn returned by rfch_get_params. Then each rx / tx window setup is relative to that 'base tn'. For TX window, you have to explicitely request an offset of 3. (this would allow for some test code to TX on ts=0 for eg.)

2010-09-17fw/layer1: Convert primitives to use common DSP/TPU scenario endingSylvain Munaut1-5/+3
Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2010-09-17fw/layer1: Add a priority field for sched_itemSylvain Munaut1-2/+2
Each item has a priority associated to it. The standard is : -4 -> Responses processing -3 -> L1S parameters changes -2 -> [Reserved for TPU window setup] -1 -> (anything) 0..7 -> Commands relative to time slot n (relative to current l1s main timeslot) 8 -> (anything) 9 -> [Reserved for TPU window cleanup] 10 -> (anthing) Note that with this modification, an item scheduled for the current frame from within a call back won't have its priority respected !

2010-09-12[layer1] Fixed double IRQ bugAndreas.Eversberg1-2/+4
During IRQ handling, disabling and enabling IRQ may cause the same IRQ to fire again. This is because the condition for this IRQ may be fullfilled again, while still handling it. Using local_firq_save() and local_irq_resore() intead, the IRQ handling will be completed before it is cleared, and may then fire again. The problem was detected during process of messages from layer23 to layer1. In the IRQ context, the TX-functions of l23_api.c are called. There, messages are queued and events are scheduled. During access to a queue or a scheduler from any IRQ context or from normal context, interrupts must be locked to prevent nested calls. If it is not desired to call l23_api.c inside IRQ context, a message queue must be used. If a message is written to that queue, it must be locked. Afterwards a signal must be sent to the main process. The main process locks the queue and de-queues the message. This is how it is done by all layer 1 drivers of mISDN.
2010-07-27include: Rename l1a_l23_interface.h to l1ctl_proto.hSylvain Munaut1-1/+1
The interface between l1 and upper layer is called by several name. IMHO l1ctl is shorted and sounds good so try to unify using that. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2010-07-13[layer1] Added mf_off to shedule next RACH request.Andreas.Eversberg1-1/+2
The mf_off value defines the offset of multiframes.

2010-06-20[L1CTL] rename primitives to comply with official naming s/_REQ/_CONF/Harald Welte1-1/+1
When L23 issues a REQ, we should respond with CONF, rather than _RESP
2010-06-20[layer1] Add L1CTL_RACH_RESP to confirm that a RACH request was sentHarald Welte1-0/+23

2010-04-09layer1: reorganize code, introduce prim_{pm,rach}.cHarald Welte1-0/+109
The new plan for layer1 is to structure the source code not based on whether it is part of l1s/l1a or other parts, but based on 'primitives'. All code that relates to transmitting a RACH burst should be in one file, same for all code related to power management. Those files are called layer1/prim_*.c
