gitlab-ci: add static analysis check
Similar to the formatting check job, take advantage of the `clang-tidy` configuration we just created to add a new job running this tool. Running `clang-tidy` requires the following: * build dependencies must be present on the system so it can resolve the includes * the build folder must be configured as it relies on the `compile_commands.json` to get build flags (such as the include paths) This could be run in the `build` job, but it would make it harder to understand the actual underlying issue, so this is executed as a new, separate job, re-using the artifacts from the `build` job.

Arnaud Ferraris	9f8ae70cba	gitlab-ci: add static analysis check Similar to the formatting check job, take advantage of the `clang-tidy` configuration we just created to add a new job running this tool. Running `clang-tidy` requires the following: * build dependencies must be present on the system so it can resolve the includes * the build folder must be configured as it relies on the `compile_commands.json` to get build flags (such as the include paths) This could be run in the `build` job, but it would make it harder to understand the actual underlying issue, so this is executed as a new, separate job, re-using the artifacts from the `build` job.	2024-11-12 13:10:43 +01:00
Arnaud Ferraris	f978b775e0	src: fix issues reported by clang-tidy Some of those are simply ignored as they're false positives.	2024-11-12 13:10:43 +01:00
Arnaud Ferraris	2c311b9022	add clang-tidy configuration This will allow us to run a static analysis tool, catching the most obvious issues (use-after-free, potential NULL dereference...) and (hopefully) increasing this software's overall robustness.	2024-11-12 13:10:43 +01:00
Arnaud Ferraris	c785f7cb8d	add gitlab CI pipeline The current pipeline (from Mobian) just doesn't work, we should get to a more efficient, simpler one. With the `clang-format` config now in place, this pipeline has 2 jobs: * ensure the code is properly formatted * run a test build to make sure it won't break	2024-11-12 13:10:43 +01:00
Arnaud Ferraris	9f6178dafd	src: format using clang-format	2024-10-30 12:01:46 +01:00
Arnaud Ferraris	57142c2c11	add clang-format configuration This will ensure our coding style is more clearly defined and allow contibutors to auto-format their code, bringing some more consistency.	2024-10-30 11:59:45 +01:00
Aren Moynihan	99aa7e2bf7	gpio: remove handling of W_DISABLE pin The PinePhone has circuitry that makes this pin active-high, but the PinePhone Pro doesn't appear to, which means we would need read active high / active low from the config file. Since the modem works fine without setting this pin, remove the logic to handle the W_DISBALE pin.	2024-10-28 16:08:37 -04:00
Aren Moynihan	ce0fc25892	at: don't clear the resetting state on sequence end If the reset sequence fails, we don't want to transition to the powered state, instead we should stay in the resetting state so we eventually timeout and try a gpio reset. If the reset command succeeds the modem will eventually send RDY and transition the state to STARTED. Since this might take longer to change the modem state, add 15 seconds (for a total of 45) to the at reset timeout just in case. It looks like the modem typically takes about 20 between sending "AT+CFUN=1,1" and receiving "RDY", so this should be plenty.	2024-10-28 12:48:08 -04:00

Aren Moynihan	541aa00198	gpio: disable airplane mode when starting the modem I'm not sure why this was being done when disabling the modem, move it to the powerup sequence for more consistency.	2024-10-21 16:54:58 -04:00
Aren Moynihan	b53702ad0b	manager: modem_reset: fix file descriptor leek fd wasn't being closed if the write failed. Theoretically if a system with an unstable modem ran for long enough, this could bring down eg25-manager.	2024-10-21 16:54:58 -04:00
Aren Moynihan	1482899888	manager: reset using gpio pins if the mode is unresponsive If the modem doesn't respond to the at reboot sequence, this will attempt reboot the modem using both the power pin and then the reset pin in case that doesn't work.	2024-10-21 16:54:58 -04:00
Aren Moynihan	c4b3b75047	manager: always set the reset line when exiting This splits the logic from gpio_check_poweroff into two separate functions, allowing the caller more control over when the reset line is asserted to force the modem to turn off. Previously if the modem didn't respond to the power key sequence in quit_app, gpio_check_poweroff wouldn't set the reset pin, and eg25-manager could leave the modem running after exiting.	2024-10-04 17:11:26 -04:00

Arnaud Ferraris	1acd15ca2f	src: gnss: fix build on 32-bit architectures It seems `off_t` is now 64-bits wide on 32-bit architectures, so using `glong` causes a build failure in this case. Switch to using the correct type from the `sendfile()` prototype to fix this.	2024-08-27 11:01:08 +02:00

On a system with the community firmware both COMM_FW and NOT_COMM_FW were set to true, with the quectel firmware only NOT_COMM_FW was true.
