There were escape backslashes around regular expression passed to grep. Because of that, grep was returning empty results as a consequence of pattern mismatch, and thus symbols pointing to original functions were not created correctly.

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.

Currently clear_screen() calls set_pixel() to set all pixels. However, the actual order of pixels being set depends on the framebuffer orientation. With NORMAL orientation, the framebuffer is accessed sequentially; with LEFT_UP/RIGHT_UP orientation, it is accessed back and forth, leading to performance drop (>1 second on bugzzy). Therefore, ensure sequential access to the framebuffer, regardless of the orientation.

2021-06-18nvs: Add Chrome OS NVS (CNVS) information to coreboot tablesFurquan Shaikh
CB:51638 separated Chrome OS NVS from global NVS by allocating it separately in CBMEM. CNVS is used in depthcharge to fill firmware information at boot time. Thus, location of CNVS needs to be shared in coreboot tables for depthcharge to use. This change adds a new coreboot table tag `CB_TAG_ACPI_CNVS`/`CB_TAG_ACPI_CNVS`(0x41) which provides the location of CNVS in CBMEM to payload (depthcharge). Additionally, CB:51639 refactored device nvs(DNVS) and moved it to the end of GNVS instead of the fixed offset 0x1000. DNVS is used on older Intel platforms like baytrail, braswell and broadwell and depthcharge fills this at boot time as well. Since DNVS is no longer used on any new platforms, this information is not passed in coreboot tables. Instead depthcharge is being updated to use statically defined offsets for DNVS. BUG=b:191324611, b:191324611 TEST=Verified that `crossystem fwid` which reads fwid information from CNVS is reported correctly on brya.

2021-02-07libpayload: Add a Makefile for in-tree payloadsNico Huber
The new `Makefile.payload` can be included by the Makefiles of pay- loads for in-tree builds. The basic idea is to use libpayload's build results without the `make install` step, and to ensure that incremental builds work. For instance, if libpayload's code changes, a `make` for the payload would automatically update the libpayload build and rebuild the payload. But if there are no code changes in libpayload, only updated files of the payload will be re-built. The configuration of libpayload is supposed to be automatically generated from a `defconfig` file. If this `defconfig` changes, libpayload and the payload will be re-built.

The keyboard self-test is required for some devices. At least one device (integrated keyboard in a ThinkPad X201) actually starts the test automatically leading to spurious output and no response for the first seconds. We wait up to 5s for the self-test result. On failure or timeout, the command will be repeated until the 30s init timer runs out. This happens all in the background of the UI polling loop. To not unnecessarily delay the boot process, we first try an oppor- tunistic initialization which skips the self-test.

2020-12-24libpayload/keyboard: Revise keyboard_cmd() error handlingNico Huber
Even if we are careful, it's still possible that we read spurious data from the keyboard, e.g. keystrokes. Namely, when we send the reset/disable command, there is a race before the command is pro- cessed. So we should always process data from the keyboard in a loop. We break it, when an ACK (0xfa) or a NAK (0xfe) is received, and warn on unexpected data unless it might be due to the mentioned race. This also gives us the opportunity to use command-specific timeouts which we take from Linux: 1s for the keyboard self-test (as there are keyboards that perform the test before acking the command) and 200ms for all other commands.

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.

This is useful for payloads to setup the translation using the decode windows already known to coreboot. Until now, there was a single decode window at the top of 4G used by all x86 platforms. However, going forward, platforms might support more decode windows and hence in order to avoid duplication in payloads this information is filled in coreboot tables. `lb_spi_flash()` is updated to fill in the details about these windows by making a call to `spi_flash_get_mmap_windows()` which is implemented by the driver providing the boot media mapping device.

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).

SMMSTORE version 2 is a complete redesign of the current driver. It is not backwards-compatible with version 1, and only one version can be used at a time. Key features: * Uses a fixed communication buffer instead of writing to arbitrary memory addresses provided by untrusted ring0 code. * Gives the caller full control over the used data format. * Splits the store into smaller chunks to allow fault tolerant updates. * Doesn't provide feedback about the actual read/written bytes, just returns error or success in registers. * Returns an error if the requested operation would overflow the communication buffer.

2020-09-18libpayload: cbgfx: Fix 'equals' counter for Lanczos resamplingYu-Ping Wu
The current initialization of the 'equals' counter is incorrect, so that when 'equals >= SSZ * SSZ', the pixels in the sample array might not be all the same, leading to a wrong pixel value being set in the framebuffer. The 'equals' counter stores the number of latest pixels that were exactly equal. Within the for loop of 'ox', the sample array is updated in a column-based order, and the 'equals' counter is updated accordingly. However, the 'equals' counter is initialized in a row-based order, which causes it to be set too large than it should be. Consider the example where sample[sx][sy] are initially: [X X X A A A] // sy = 0 [X X X B B B] [X X X B B B] [X X X B B B] [X X X B B B] [X X X B B B] // sy = SSZ Then, the correct implementation will initialize 'equals' to be 15, with last_equal being B. Suppose all of the remaining pixels are B. Then, at the end of the 'while (fpfloor(ixfp) > ix)' loop when ix = 4, or equivalently after 4 more columns of sample are updated, 'equals' will be 15 + 6 * 4 = 39, which is greater than SSZ * SSZ = 36, but we can see there are still 2 A's in the sample: [B B B B A A] [B B B B B B] [B B B B B B] [B B B B B B] [B B B B B B] [B B B B B B] Therefore, we must also initialize the 'equals' counter in a column-based order.

2020-09-13libpayload: malloc: Fix realloc for overlapping buffersYu-Ping Wu
The current realloc() works by freeing the origin buffer, allocating a new one, and copying the data over. It's true that free() won't touch the actual memory. However, the alloc() following it will potentially modify the memory that belongs to the old buffer in order to create a new free block (right after the newly allocated block). This causes 8 bytes (HDRSIZE) to be overwritten before being copied to the new buffer. To fix the problem, we must create the header of the new free block after the data is copied. In this patch, the content of alloc() is split into two functions: 1. find_free_block(): Find a free block with large enough size, without touching the memory 2. use_block(): Update the header of the newly allocated block, and create the header of the new free block right after it Then, inside realloc(), call memmove() call right after find_free_block() while before use_block().

default_memmove() calls memcpy() when (src > dst). This is safe for the default_memcpy() implementation, but just calling memcpy() may invoke an architecture-specific implementation. Architectures are free to implement memcpy() however they want and may assume that buffers don't overlap in either direction. So while this happens to work for all current architecture implementations of memcpy(), it's safer not to rely on that and only rely on the known implementation of default_memcpy() for the forwards-overlapping case.
