2024-01-09test: hush: dollar: fix bugous behaviorIon Agorria
The dollar test was merged with bugous console behavior, and instead of fixing it, this behavior was just workarounded. It seems like without the fix the ut_assert_skipline(); didn't clear console and running ut_assert_skipline(); many times would give always OK. With lib: membuff: fix readline not returning line in case of overflow the line is cleared correctly and next assert fails because now there is nothing to clean which is correct if we look the this a bit above the failing assert: if (gd->flags & GD_FLG_HUSH_MODERN_PARSER) { /* * For some strange reasons, the console is not empty after * running above command. * So, we reset it to not have side effects for other tests. */ console_record_reset_enable(); } else if (gd->flags & GD_FLG_HUSH_OLD_PARSER) { ut_assert_console_end(); } Which further confirms that tests workaround the old problem and now that problem is fixed we can remove the whole if blocks and simply place ut_assert_console_end() right after ut_assert_skipline() without any conditional and will pass green. So this part of code goes from: ut_assert_skipline(); ut_assert_skipline(); if (gd->flags & GD_FLG_HUSH_MODERN_PARSER) { /* See above comments. */ console_record_reset_enable(); } else if (gd->flags & GD_FLG_HUSH_OLD_PARSER) { ut_assert_console_end(); } to become: ut_assert_skipline(); ut_assert_console_end(); Same thing should be done with the if block mentioned above that calls console_record_reset_enable().

2024-01-07acpi: Write pointers to tables instead of addressesSimon Glass
Sandbox uses an API to map between addresses and pointers. This allows it to have (emulated) memory at zero and avoid arch-specific addressing details. It also allows memory-mapped peripherals to work. As an example, on many machines sandbox maps address 100 to pointer value 10000000. However this is not correct for ACPI, if sandbox starts another program (e.g EFI app) and passes it the tables. That app has no knowledge of sandbox's address mapping. So to make this work we want to store 10000000 as the value in the table. Add two new 'nomap' functions which clearly make this exeption to how sandbox works. This should allow EFI apps to access ACPI tables with sandbox, e.g. for testing purposes. Signed-off-by: Simon Glass <sjg@chromium.org> Suggested-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2023-12-28Merge patch series "Modernize U-Boot shell"Tom Rini
Francis Laniel <francis.laniel@amarulasolutions.com> says: During 2021 summer, Sean Anderson wrote a contribution to add a new shell, based on LIL, to U-Boot [1, 2]. While one of the goals of this contribution was to address the fact actual U-Boot shell, which is based on Busybox hush, is old there was a discussion about adding a new shell versus updating the actual one [3, 4]. So, in this series, with Harald Seiler, we updated the actual U-Boot shell to reflect what is currently in Busybox source code. Basically, this contribution is about taking a snapshot of Busybox shell/hush.c file (as it exists in commit 37460f5da) and adapt it to suit U-Boot needs. This contribution was written to be as backward-compatible as possible to avoid breaking the existing. So, the modern hush flavor offers the same as the actual, that is to say: 1. Variable expansion. 2. Instruction lists (;, && and ||). 3. If, then and else. 4. Loops (for, while and until). No new features offered by Busybox hush were implemented (e.g. functions). It is possible to change the parser at runtime using the "cli" command: => cli print old => cli set modern => cli print modern => cli set old The default parser is the old one. Note that to use both parser, you would need to set both CONFIG_HUSH_MODERN_PARSER and CONFIG_HUSH_OLD_PARSER. In terms of testing, new unit tests were added to ut to ensure the new behavior is the same as the old one and it does not add regression. Nonetheless, if old behavior was buggy and fixed upstream, the fix is then added to U-Boot [5]. In sandbox, all of these tests pass smoothly: => printenv board board=sandbox => ut hush Running 20 hush tests ... Failures: 0 => cli set modern => ut hush Running 20 hush tests ... Failures: 0 Thanks to the effort of Harald Seiler, I was successful booting a board: => printenv fdtfile fdtfile=amlogic/meson-gxl-s905x-libretech-cc.dtb => cli get old => boot ... root@lepotato:~# root@lepotato:~# reboot ... => cli set modern => cli get modern => printenv fdtfile fdtfile=amlogic/meson-gxl-s905x-libretech-cc.dtb => boot ... root@lepotato:~# This contribution indeed adds a lot of code and there were concern about its size [6, 7]. With regard to the amount of code added, the cli_hush_upstream.c is 13030 lines long but it seems a smaller subset is really used: gcc -D__U_BOOT__ -E common/cli_hush_upstream.c | wc -l 2870 Despite this, it is better to still have the whole upstream code for the sake of easing maintenance. With regard to memory size, I conducted some experiments for version 8 of this series and for a subset of arm64 boards and found the worst case to be 4K [8]. Tom Rini conducted more research on this and also found the increase to be acceptable [9]. If you want to review it - your review will really be appreciated - here are some information regarding the commits: * commits marked as "test:" deal with unit tests. * commit "cli: Add Busybox upstream hush.c file." copies Busybox shell/hush.c into U-Boot tree, this explain why this commit contains around 12000 additions. * commit "cli: Port Busybox 2021 hush to U-Boot." modifies previously added file to permit us to use this as new shell. The really good idea of #include'ing Busybox code into a wrapper file to define some particular functions while minimizing modifications to upstream code comes from Harald Seiler. * commit "cmd: Add new parser command" adds a new command which permits selecting parser at runtime. I am not really satisfied with the fact it calls cli_init() and cli_loop() each time the parser is set, so your reviews would be welcomed. * Other commits focus on enabling features we need (e.g. if).

2023-12-13cmd: acpi: fix acpi list commandHeinrich Schuchardt
ACPI tables may comprise either RSDT, XSDT, or both. The current code fails to check the presence of the RSDT table before accessing it. This leads to an exception if the RSDT table is not provided. The XSDT table takes precedence over the RSDT table. The return values of list_rsdt() and list_rsdp() are always zero and not checked. Remove the return values. Addresses in the XSDT table are 64-bit. Adjust the output accordingly. As the RSDT table has to be ignored if the XSDT command is present there is no need to compare the tables in a display command. Anyway the specification does not require that the sequence of addresses in the RSDT and XSDT table are the same. The FACS table header does not provide revision information.

2023-12-13Merge patch series "bootm: Refactoring to reduce reliance on CMDLINE (part A)"Tom Rini
To quote the author: It would be useful to be able to boot an OS when CONFIG_CMDLINE is disabled. This could allow reduced code size. Standard boot provides a way to handle programmatic boot, without scripts, so such a feature is possible. The main impediment is the inability to use the booting features of U-Boot without a command line. So the solution is to avoid passing command arguments and the like to code in boot/ A similar process has taken place with filesystems, for example, where we have (somewhat) separate Kconfig options for the filesystem commands and the filesystems themselves. This series starts the process of refactoring the bootm logic so that it can be called from standard boot without using the command line. Mostly it removes the use of argc, argv and cmdtbl from the internal logic. Some limited tidy-up is included, but this is kept to smaller patches, rather than trying to remove all #ifdefs etc. Some function comments are added, however. A simple programmatic boot is provided as a starting point. This work will likely take many series, so this is just the start. Size growth with this series for firefly-rk3288 (Thumb2) is: arm: (for 1/1 boards) all +23.0 rodata -49.0 text +72.0 This should be removed by: https://source.denx.de/u-boot/custodians/u-boot-dm/-/issues/11 but it is not included in this series as it is already large enough. No functional change is intended in this series. Changes in v3: - Add a panic if programmatic boot fails - Drop RFC tag Changes in v2: - Add new patch to adjust position of unmap_sysmem() in boot_get_kernel() - Add new patch to obtain command arguments - Fix 'boot_find_os' typo - Pass in the command name - Use the command table to provide the command name, instead of "bootm"
