We have licensed the code under GNU Afffero Public License,
and state that in the first paragraph as well as in the link
to the license. However, a paragraph in the middle stated
"see the GNU General Public License", which is somewhat misleading.
Let's fix that.

At the time the phy link / phy instance level VTY configuration
commands are parsed, we did not yet call l1if_open() and thus
pinst->u.{lc15,sysmobts}.hdl == NULL.
PHY or PHY instance specific configuration must thus be stored inside
the phy_link or phy_instance itself, and not inside the (not yet
existing) handle.
We solve this by moving around some parameters:
* clk_use_eeprom/clk_cal/clk_src/calib_path get replicated in
phy_instance
* min_qual_{rach,norm} are moved into the generic part (which means
that osmo-bts-octphy and osmo-bts-trx should also implement them)

API revision 5.1 allows us to pass a version number for the rx/tx
calibration and the DSP/FPGA will inform us about clock errors.
|
|
When enqueueing a command towards the L1, we can now pass along
a private data pointer, which then gets passed to the call-back
upon completion.

calib_file.c: In function 'next_calib_file_idx':
calib_file.c:126:3: warning: implicit declaration of function 'band_femto2osmo' [-Wimplicit-function-declaration]
|
|
The information from band_mask has never been used as the return
was executed unconditionally.
Fixes: Coverity CID 1113473
|
|
Even if one calibration table cannot be loaded, continue to try to
load the other tables, instead of aborting very early.
|
|
If L1 tells us that a certain band is not supported, then there is no
point in even trying to read+load calibration tables from EEPROM or
files.

Coverity wants us to check that fscanf has scanned the amount of
variables we want to have. Initialize the scan result to 0/0.0f
and warn if the scan has failed.
Fixes: Coverity CID 1040774, CID 1040773

Close the cached file descriptor once the calibration data is
loaded and applied.

This should fix:
calib_file.c: In function 'calib_eeprom_read':
calib_file.c:262: error: 'SuperFemto_SetRxCalibTblReq_t' undeclared (first use in this function)
calib_file.c:262: error: (Each undeclared identifier is reported only once
calib_file.c:262: error: for each function it appears in.)

This should fix:
calib_file.c: In function 'calib_fixup_rx':
calib_file.c:148: error: 'SuperFemto_SetRxCalibTblReq_t' undeclared (first use in this function)

Make sure the l1msg is always freed in the callback. There were
several error conditions were the msgb would not have been freed,
in the case of the calib data and the system information the message
was not freed even in normal condition.
I will modify this code to __use a msgb. This allows to re-use
the allocated msgb across read operations.

|
For certain sysmoBTS units, a fixup to the calibration table is needed,
if the firmware is >= 3.3.0.
|
|
On v2D (and later) hardware, the calibration data can be read directly
from the EEPROM and doesn't have to be read from files.
If there is no trx-calib-path set in the VTY, we will read from EEPROM.
|
|
In case opening a calibration file is failing an error will will be
logged, the caller and implementation were inconsistent about the API
version that is supported for the calibration data, attempt to make
the cut-off at 2.4.0.

All users (but the gsm_compl) of the l1if_req_compl use it with
is_system_primitive=1. We can now remove this parameter from the
method. Introduce _l1if_req_compl that will insert the item into
the queue for us.
|
|
|
|
l1if_gsm_req_compl everyone is passing the trx as data pointer right
now, remove it from the request procedure right now as it can be
deducted from the femtol1_hdl.

'trx-calibration-path' is the new VTY command indicating the path
name where the calibration files can be found.
Calibration is only implemented for SUPERFEMTO API version 2.4.0 or
later.

... and convert them to L1 primitives. The code is not yet used.
