* Shell: Handle aborting loops betterSascha Hauer2019-04-241-1/+1
| | | | | | | | | | | | | | | | | | It's easy to get stuck in an infinite loop in the hush shell: while true; do sleep 1; done The 'sleep' command will check for ctrl-c with the ctrlc() function. This will abort the sleep command. Hush then checks for ctrl-c again in the loop. The ctrl-c in the buffer has already been eaten by the sleep command, so the loop will continue. With this patch we remember the presence of a ctrl-c character in a variable instead of checking for a new character each time. The variable must be resetted explicitly by calling ctrlc_handled() which will be called by the shell in the outer loop. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* sandbox: new --stdinout option to enable a bidirectional consoleAleksander Morgado2017-06-061-11/+42
| | | | | | | | | In addition to allowing read-only and write-only consoles with --stdin and --stdout, we now allow bidirectional read/write consoles with FIFO files. This is e.g. to allow doing RATP over the FIFO based consoles. Signed-off-by: Aleksander Morgado <aleksander@aleksander.es> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* sandbox: Fix registering file/fifo consolesSascha Hauer2017-06-011-19/+19
| | | | | | | | barebox_register_console() uses xzalloc which requires the malloc pool to be initialized, so call it during the second option parsing when this is already done. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* sandbox: fix registering multiple consolesAleksander Morgado2017-06-011-3/+3
| | | | | | | | | | | | | | | | | | Consoles need to be registered with the "console" device name so that they are probed by the correct driver. The barebox_register_console() was already forcing this as it was overwriting the name that was being passed as argument, but it was failing to provide a unique id for each new console, so the underlying register_device() would just return an error when wanting to re-register a device with device name "console" and id 0. We remove the unused name parameter from barebox_register_console() as it is really nowhere used, and also specify DEVICE_ID_DYNAMIC as id, so that a new unique device id is given to each newly registered console device.

* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.

| | | | | | | | | | | | This patch makes it possible to specify the device name of a file added to the sandbox via the --image paramter, e.g.: barebox --image foo=bar.image This means the file "bar.image" is added as "/dev/foo" to the sandbox.

* Only pass -P to cpp when generating ld scriptsLoïc Minier2011-10-181-1/+0
| | | | | | | | | | | | | | | | | | | | | | | When building sandbox with ccache, one would hit warnings such as: warning: 'struct mmsghdr' declared inside parameter list on random files; a way to reproduce this issue is to build a simple file doing just: #include <sys/socket.h> int main(void) { return 0; } gcc -Wall -P -c -o foo foo.c But actually the -P flag is only useful when generating non-C files, such as linker scripts in the case of barebox. Removing the -P flag from all the gcc invocations, except when generating .lds files makes the warning go away. It turns out that this is what linux/scripts/Makefile.build also does nowadays.

* sandbox: add longopts and fix segfaultRobert Schwebel2010-09-211-14/+32
| | | | | | | | | | | | | | | Until now, the main function of the sandbox port wants to use the libc getopt(), but as we have a getopt() implementation in barebox as well, it is silently used instead. This works in the usual case, but if an error occurs (i.e. by using an unknown argument) in getopt(), the implementation tries to write to the console, which is not initialized and thus breaks with a null pointer exception. This patch changes the main function to use getopt_long() instead of getopt(). This makes us use the implementation in glibc and while being there, we get long options, which makes us look more professional... Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
