2024-06-16console: Only add non-stub code to romstage if SEPARATE_ROMSTAGE=yNicholas Chin
If both CONFIG_SEPARATE_ROMSTAGE and CONFIG_BOOTBLOCK_CONSOLE are not set, compilation will fail with errors indicating redefinitions of various console methods. When BOOTBLOCK_CONSOLE is not set, the __CONSOLE_ENABLE__ macro in include/console/console.h evaluates to zero when compiling the bootblock, resulting in various console methods being defined as stubs in the header. In a typical build with a separate bootblock and romstage, this will not cause a conflict as the non-stub definitions found in the console/*.c files are added conditionally to the bootblock depending on CONFIG_BOOTBLOCK_CONSOLE. When SEPARATE_ROMSTAGE is not set, the list of romstage objects gets added to the bootblock. Since the console sources were unconditionally added to romstage, the non-stub definitions were able to slip into the bootblock, causing a redefinition of the stubs. Avoid this by conditionally adding these sources to romstage depending on CONFIG_SEPARATE_ROMSTAGE. If SEPARATE_ROMSTAGE is set, the non-stub definitions are handled in the same way as they were before. If it is not set, the union of bootblock and romstage objects will only include the non-stub definitions based on CONFIG_BOOTBLOCK_CONSOLE, which uses existing console/Makefile.mk rules for the bootblock. TEST=qemu-i440fx builds successfully with all possible settings of CONFIG_SEPARATE_ROMSTAGE and CONFIG_BOOTBLOCK_CONSOLE.

2023-11-09Allow to build romstage sources inside the bootblockArthur Heymans
Having a separate romstage is only desirable: - with advanced setups like vboot or normal/fallback - boot medium is slow at startup (some ARM SOCs) - bootblock is limited in size (Intel APL 32K) When this is not the case there is no need for the extra complexity that romstage brings. Including the romstage sources inside the bootblock substantially reduces the total code footprint. Often the resulting code is 10-20k smaller. This is controlled via a Kconfig option. TESTED: works on qemu x86, arm and aarch64 with and without VBOOT.

2022-12-17lib: Hook up libhwbase in romstageJeremy Compostella
It's hidden behind the configuration option `CONFIG_ROMSTAGE_LIBHWBASE'. This also adds some glue code to use the coreboot console for debug output and our monotonic timer framework as timer backend. Running Ada code in romstage and more particular libhwbase brings a few challenges as global initialized variables are not supported in Cache-As-Ram mode. 1. The libhwbase dynamic mmio driver implementation makes the Gnat compiler generate some global initialized variables. For this reason, when compiled for romstage or for romstage and ramstage the static mmio driver is enforced (`HWBASE_STATIC_MMIO'). 2. The Gnat compiler generates elaboration functions to initialize program data at runtime. These elaboration functions are called by the romstage_adainit() function. The data references symbols suffixed by `_E'. Even though these symbols, at compilation time, do not contain any data and are filled with zeros, the Gnat compiler installs them in the .data section. Since these symbols are actually filled with zeros, it is safe to install them in the .bss section. cf. https://docs.adacore.com/gnat_ugn-docs/html/gnat_ugn/gnat_ugn/elaboration_order_handling_in_gnat.html#elaboration-code This patch requires the libhwbase https://review.coreboot.org/c/libhwbase/+/69854 CL.

In order to provide the same loglevel prefixes and highlighting that were recently introduced for "interactive" consoles (e.g. UART) to "stored" consoles (e.g. CBMEM) but minimize the amont of extra storage space wasted on this info, this patch will write a 1-byte control character marker indicating the loglevel to the start of every line logged in those consoles. The `cbmem` utility will then interpret those markers and translate them back into loglevel prefixes and escape sequences as needed. Since coreboot and userspace log readers aren't always in sync, occasionally an older reader may come across these markers and not know how to interpret them... but that should usually be fine, as the range chosen contains non-printable ASCII characters that normally have no effect on the terminal. At worst the outdated reader would display one garbled character at the start of every line which isn't that bad.

2022-02-07console: Add ANSI escape sequences for highlightingJulius Werner
This patch adds ANSI escape sequences to highlight a log line based on its loglevel to the output of "interactive" consoles that are meant to be displayed on a terminal (e.g. UART). This should help make errors and warnings stand out better among the usual spew of debug messages. For users whose terminal or use case doesn't support these sequences for some reason (or who simply don't like them), they can be disabled with a Kconfig. While ANSI escape sequences can be used to add color, minicom (the presumably most common terminal emulator for UART endpoints?) doesn't support color output unless explicitly enabled (via -c command line flag), and other terminal emulators may have similar restrictions, so in an effort to make this as widely useful by default as possible I have chosen not to use color codes and implement this highlighting via bolding, underlining and inverting alone (which seem to go through in all cases). If desired, support for separate color highlighting could be added via Kconfig later.

Chromebooks normally run with non-serial enabled firmware because writing to the UART console is very slow. This unfortunately makes debugging boot errors more difficult. We tend to rely on port 80s and/or the vboot recovery code. When CONSOLE_CBMEM_DUMP_TO_UART is selected it will dump the entire cbmem console to the UART whenever `vboot_reboot()` is called. We don't incur any boot time penalty in the happy path, but still retain the ability to access the logs when an error occurs. The previous implementation was using a hard coded UART index and `get_uart_baudrate` was always returning 0 since `CONFIG_TTYS0_BAUD` wasn't defined. This change makes it so the UART console properties are available when CONSOLE_CBMEM_DUMP_TO_UART is set. This results in the following .config diff: +CONFIG_UART_FOR_CONSOLE=0 +CONFIG_TTYS0_BASE=0x3f8 +CONFIG_TTYS0_LCS=3 +CONFIG_CONSOLE_SERIAL_115200=y +CONFIG_TTYS0_BAUD=115200 This functionality is especially helpful on Guybrush. PSP Verstage is run on S0i3 resume. Today, if there is an error, the cbmem console is lost since it lives in the PSP SRAM. BUG=b:213828947, b:215599230 TEST=Build non-serial guybrush FW and verify no serial output happens in happy path. Inject a vboot error and perform an S0i3 suspend/resume. Verify CBMEM console gets dumped to the correct UART.

2022-01-17console: Add Kconfig to dump pre-bootblock cbmem contentsRaul E Rangel
Pre-bootblock stages (i.e., VBOOT_STARTS_BEFORE_BOOTBLOCK) might not have the ability to log to the UART, so their console messages are inaccessible until the boot processes gets into the payload or OS. This makes it difficult to debug verstage. This feature will dump the pre-bootblock CBMEM console immediately after the bootblock console is initialized. I chose to do this in console_init instead of bootblock_soc_init because I wanted to have the pre-bootblock contents dumped before the coreboot bootblock starting message is printed.

2019-12-11printf: Automatically prefix %p with 0xJulius Werner
According to the POSIX standard, %p is supposed to print a pointer "as if by %#x", meaning the "0x" prefix should automatically be prepended. All other implementations out there (glibc, Linux, even libpayload) do this, so we should make coreboot match. This patch changes vtxprintf() accordingly and removes any explicit instances of "0x%p" from existing format strings. How to handle zero padding is less clear: the official POSIX definition above technically says there should be no automatic zero padding, but in practice most other implementations seem to do it and I assume most programmers would prefer it. The way chosen here is to always zero-pad to 32 bits, even on a 64-bit system. The rationale for this is that even on 64-bit systems, coreboot always avoids using any memory above 4GB for itself, so in practice all pointers should fit in that range and padding everything to 64 bits would just hurt readability. Padding it this way also helps pointers that do exceed 4GB (e.g. prints from MMU config on some arm64 systems) stand out better from the others.

Because the function is implemented in C, post_code() calls from cache_as_ram.S and other early assembly entry files may not currently work for cold boots.

Implicit fall throughs are a perpetual source of bugs and Coverity Scan issues, so let's squash them once and for all. GCC can flag implicit fall throughs using the -Wimplicit-fallthrough warning, and this should ensure no more enter the code base. However, many fall throughs are intentional, and we can use the following comment style to have GCC suppress the warning. switch (x) { case 1: y += 1; /* fall through */ case 2: y += 2; /* fall through - but this time with an explanation */ default: y += 3; } This patch adds comments for all remaining intentional fall throughs, and tweaks some existing fall through comments to fit the syntax that GCC expects.
