* console: flush consoles on newline when debuggingAhmad Fatoum2024-03-131-1/+4
| | | | | | | | | | | | | | | For debugging hangs, CONFIG_DEBUG_PROBES and CONFIG_DEBUG_INITCALLS are useful tools to pinpoint where the issue is. FOr issues that lock up the SoC, their output can be misleading if we have bigger UART FIFO and not all output has managed to make it out. Add a new DEBUG_FLUSH_LINE_BREAK to make debugging this easier. The option is unnecessary outside of debugging, so for now we don't add a prompt by default and select it as needed.

* console: don't fixup baud rate into earlycon stringAhmad Fatoum2023-05-231-2/+2
| | | | | | | | | | | | | | | | | By design, earlycon depends on boot firmware to setup the console for Linux to use early before proper driver probe. When we specify the baudrate though, the earlycon implementation may configure UART-internal dividers to try to achieve the specified baudrate. The bus clock being divided is defined statically Linux-architecture-wide using the BASE_BAUD symbol, which is not suitable across different baudrates and SoCs. Side step this issue by skipping fix up of the baudrate, so Linux just uses what was preconfigured. This fixed global.bootm.earlycon=1 for the ROCK-3A with 1.5 MBaud.

* Rename struct device_d to deviceSascha Hauer2023-01-101-2/+2
| | | | | | | | | | | | | The '_d' suffix was originally introduced in case we want to import Linux struct device as a separate struct into barebox.

* console: add new $global.bootm.earlycon parameterAhmad Fatoum2022-06-091-0/+17
| | | | | | | | | | | | | | | | | | | barebox already fixes up a suitable console= parameter if it can determine one into the kernel command line. This doesn't help with early Linux issues, which can instead be debugged by the earlycon mechanism. For earlycon to work, the kernel DT must have a stdout-path or the user needs to explicitly specify what driver to use and how to access it (base address, optionally access_type). Make this easier by just having barebox fix up the needed information when $global.bootm.earlycon is true and the barebox serial driver provides the needed information. If the serial driver doesn't, a plain "earlycon" parameter will be fixed up.

| | | | | | | | | | | ctrlc is allowed only after init and reboot mode scripts have run, so these scripts run uninterruptible. A side effect of this is that all calls to ctrlc() will immediately return with false without running the pollers. While init scripts shouldn't run too long, it's still surprising behavior.

| | | | | | | | | | | | | | | | | | Trying to output a single character via echo -a /dev/serial0-1 currently results in garbage output after the newline, because console.c's fops_write discards the buffer length and passes the buffer to (struct cdev)::puts which only handles NUL-terminated strings. Fix this by amending (struct cdev)::puts with a new nbytes parameter, which is correctly propagated. All this functions now return at most the nbytes parameter they were passed in. This fixes __console_puts, which used to count new lines twice in its return value.

* console: forbid ctrlc during startupSascha Hauer2019-04-241-0/+24
| | | | | | | | | | | | | | | When global.autoboot_abort_key is set to ctrl-c then the user is expected to press ctrl-c to get to the prompt. The user might press ctrl-c before the init script runs the "timeout" command. In this case the init script is aborted at arbitrary places which leads to inconsistent results depending on the place it is aborted. This patch introduces the global.console.ctrlc_allowed variable. When this variable is set to false ctrl-c is ignored entirely. The variable is set to false by default and changed to true in the init script. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Shell: Handle aborting loops betterSascha Hauer2019-04-241-5/+23
| | | | | | | | | | | | | | | | | | 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>

"access" can be empty for regular read/write parameter, "_ro" for readonly parameters which get their value from a variable pointer in the background or "_fixed" for parameters which are set to a fixed value (without a pointer in the background).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the ability to control barebox over serial lines. The regular console is designed for human input and is unsuitable for controlling barebox from scripts since characters can be lost on both ends, the data stream contains escape sequences and the prompt cannot be easily matched upon. This approach is based on the RATP protocol. RATP packages start with a binary 0x01 which does not occur in normal console data. Whenever a 0x01 character is detected in the console barebox goes into RATP mode. The RATP packets contain a simple structure with a command/respone type and data for that type. Currently defined types are: BB_RATP_TYPE_COMMAND (host->barebox): Execute a command in the shell BB_RATP_TYPE_COMMAND_RETURN (barebox->host) Sends return value of the command back to the host, also means barebox is ready for the next command BB_RATP_TYPE_CONSOLEMSG (barebox->host) Console message from barebox Planned but not yet implemented are: BB_RATP_TYPE_PING (host->barebox) BB_RATP_TYPE_PONG (barebox->host) For testing purposes BB_RATP_TYPE_GETENV (host->barebox) BB_RATP_TYPE_GETENV_RETURN (barebox->host) Get values of environment variables Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Tested-by: Andrey Smirnov <andrew.smirnov@gmail.com>
