2022-01-10libpayload: Enable vboot integrationJakub Czapiga
This patch introduces building and linking of 3rdparty/vboot with libpayload. VBoot can be enabled by setting CONFIG_LP_VBOOT_LIB. Moreover it can be configured to use either TPM or TPM 2.0 mode, and whether to use SHA256 processor extension instructions on x86.

2021-10-11libpayload: Add mock architectureJakub Czapiga
Mock architecture can be used to build libpayload using host compiler. It can be enabled by setting ARCH_MOCK=y in the dotconfig. It sets LITTLE_ENDIAN=y, as most machines these days use little-endian CPUs. Libpayload will use HOSTCC as CC, HOSTLD as LD, etc. instead of tools provided by xcompile. Mock architecture configuration can be used by payloads for testing purposes. Thanks to it, tests can be architecture-independent, and can be executed without requiring compatible Kconfig options, e.g. ARCH_ARM64=y for ARM64 machine. However, one has to provide implementation for most architecture-specific functions present in arch/* directories.

Add a Kconfig option to set the keyboard translation state on exit and set the default to true. This restores the keyboard to the power-up defaults for firmware that does not always run libpayload keyboard init to have consistent state, and provides an option to disable translation for keyboards that might need it.

2020-12-23libpayload/keyboard: Revise scancode set and translation configNico Huber
Some background first: The original XT keyboards used what we call scancode set #1 today. The PC/AT keyboards introduced scancode set #2, but for compatibility, its controller translated scancodes back to set #1 by default. Newer keyboards (maybe all we have to deal with) also support switching the scancode set. This means the translation option in the controller and the scancode set selection in the keyboard have to match. In libpayload, we only support set #1 scancodes. So we either need the controller's trans- lation on and set #2 selected in the keyboard, or the controller's translation off and set #1 selected in the keyboard. Valid configurations: * SET #1 + XLATE off * SET #2 + XLATE on Both with and without the PC_KEYBOARD_AT_TRANSLATED option, we were only configuring one of the two settings, leaving room for invalid configurations. With this change, we try to select scancode set #2 first, which seems to be the most supported one, and configure the controller's translation accordingly. We try to fall back to set #1 on failure. We also keep translation disabled during configuration steps to ensure that the controller doesn't accidentally translate confi- guration data. On the coreboot side, we leave the controller's translation at its default setting, unless DRIVERS_PS2_KEYBOARD is enabled. The latter enables the translation unconditionally. For QEMU this means that the option effectively toggles the translation, as QEMU's controller has it disabled by default. This probably made a lot of earlier testing inconsistent. Fixes: commit a95a6bf646 (libpayload/drivers/i8402/kbd: Fix qemu) The reset introduced there effectively reverted the scancode selection made before (because 2 is the default). It's unclear if later changes to the code were only necessary to work around it.

2020-11-02libpayload: Add support for link time optimizationJacob Garber
Link time optimization is a technique for whole-program optimization. Instead of doing code generation during compilation, the compiler saves its intermediate representation to the object files. During the final linking step, it will then merge all the object files together and perform optimizations on the entire program. This can often reduce the final binary size, but also may increase the total compilation time. This patch introduces a Kconfig option for enabling link time optimization in libpayload. Since libpayload does no linking of its own, its LTO archive files will contain only IR and no generated code. Downstream projects will need to use LTO-aware tools when manipulating the archives (eg. gcc-ar and gcc-nm), but otherwise do not need to use LTO themselves -- the compiler will recognize which files are LTO and which are not, so enabling this option should mostly be "drop in". For example, when building coreinfo.elf using tinycurses libpayload: binary size compilation time default 114 KiB 11.49s LTO 95 KiB 10.36s In this case the total compilation time was actually shorter -- despite the final linking step taking longer, this was offset by the shorter compilation times for each individual file (since there is no code gen until the very end).

2020-07-09libpayload: cbgfx: Replace bilinear resampling with LanczosJulius Werner
This patch improves the image resampling (scaling) code in CBGFX to use the Lanczos algorithm that is widely considered the "best" resampling algorithm (e.g. also the first choice in Python's PIL library). It is of course much more elaborate and therefore slower than bilinear resampling, but a lot of the difference can be made up with optimizations, and the resulting code was found to still produce acceptable speeds for existing Chrome OS UI use cases (on an Arm Cortex-A55 device, time to scale an image to 1101x593 went from ~88ms to ~275ms, a little over 3x slowdown). Nevertheless, if this should be too slow for anyone there's also an option to tune it down a little, but still much better than bilinear (same operation was ~170ms with this).

2019-03-02libpayload: keyboard: Add option to ignore failures during initDuncan Laurie
If keys are pressed at boot some keyboard controllers will not properly respond with an ACK to commands, which results in the keyboard_init function aborting before it adds the keyboard to the input device list. This same keyboard controller will manage to properly return keyboard data when keys are pressed later, so it is possible for it to be functional in the payload even if it does not respond properly to every command during initialization. In order to allow payloads to use the keyboard when this happens a new Kconfig option is added to ignore the keyboard ACK response and always add the keyboard to the input device list. This option is disabled by default and must be enabled by the specific boards that need it. BUG=b:126633269 TEST=boot on device with this controller and press keys during boot and see that the keyboard is still functional in the payload.

2016-10-17libpayload: Reintroduce CONFIG_LP_CHROMEOS to set suitable defaultsJulius Werner
Chrome OS builds always have some inherent differences to "standard" libpayload configurations: they don't want to use curses or things like storage drivers, they always use the coreboot framebuffer and USB, etc. This patch reintroduces CONFIG_LP_CHROMEOS as an option that only affects Kconfig defaults. This allows Chrome OS builds to select most of what they need in one go and reduces board-specific .config files to only the options that are really specific to that board. Also restricts the 8250_SERIAL_CONSOLE Kconfig to only default to yes on x86 boards, which probably makes sense for all of libpayload (some but far from all ARM boards use 8250-compatible UARTs, and we should probably not default a platform option unless it's going to be correct with very high probability).

2015-11-28libpayload: Remove redundant 8250 MMIO32 UART driverAlexandru Gagniuc
The more generic 8250 driver can handle both port-mapped and memory- mapped 8250-compatible UARTs, with different register sizes. Thus, a separate driver for MMIO32 is not needed. The generic 8250 driver was tested to work for both output and input, on Apollolake SoC, which only presents an MMIO32 UART.

2015-07-09libpayload: Add LZ4 decompression algorithmJulius Werner
This patch adds support for the LZ4 decompression algorithm to libpayload. It's what all the cool kids are using for decompression these days and has many interesting advantages over LZMA (and everything else I know of): blazing fast decompression (20(!) times faster than LZMA, twice as fast as LZO on my Cortex-A72), no memory requirements on decompression, and possibly in-place decompression support. It pays for that with a lower compression ratio (about 50% larger compressed size than LZMA, 10% larger than LZO for an ARM64 Linux kernel binary), but the boot time math still works in its favor for our IO speeds. This patch only adds the raw decompression functions for use by external payloads, we can later try integrating them in CBFS. It copies the decompression code itself unmodified from the upstream LZ4 library at github.com/Cyan4973/lz4 which will hopefully make it easy to update. The frame format parsing is reimplemented since the upstream version looks unnecessarily complex and unreadable for our needs. BRANCH=smaug BUG=chrome-os-partner:32184 TEST=With other patches, booted ARM64 kernel that got compressed from 15M to 5.1M and decompresses in 44ms.
