2020-11-16libpayload/i8042: Increase response timeout to 1.5sNico Huber
The current timeout of 500ms is too low. For instance self-test of the KBC integrated into IT8516E took almost 1s in tests. We already check for presence of the KBC before the self-test. So the timeout should only trigger on a hardware defect and we can leave some margin.

2020-11-08libpayload: Make OHCI enums into typesJacob Garber
The OHCI header file declares various enums as follows: enum { ... } enum_name; Since the name is at the end, this is actually declaring a variable called enum_name and *not* a type, which is causing a multiple definition error in GCC 10. Move the enum_name before the opening brace to prevent this.

2020-11-08libpayload: Add compiler.h to compiler parametersJacob Garber
Headers in libpayload define various structs like so: struct struct_name { ... } __packed; However, these header files do not include the compiler.h macro that defines what __packed is, so they are actually defining a variable named __packed and *not* declaring a packed struct. This leads to defining the same variable multiple times, which was caught by GCC 10. Add compiler.h to the compiler parameters so it is included in all files automatically.

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).

We can skip the PIT-based TSC calibration if we can derive the invariant TSC rate from CPUID/MSR data. This is necessary if the PIT is disabled, which is the default, for instance, on Coffee Lake CPUs. This implementation should cover all Intel Core i processors at least.

2020-10-22drivers/smmstore: Implement SMMSTORE version 2Patrick Rudolph
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. Separate the SMMSTORE into 64 KiB blocks that can individually be read/written/erased. To be used by payloads that implement a FaultTolerant Variable store like TianoCore. The implementation has been tested against EDK2 master. An example EDK2 implementation can be found here: https://github.com/9elements/edk2-1/commit/eb1127744a3a5d5c8ac4e8eb76f07e79c736dbe2 Change-Id: I25e49d184135710f3e6dd1ad3bed95de950fe057 Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Signed-off-by: Christian Walter <christian.walter@9elements.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40520 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Michał Żygowski <michal.zygowski@3mdeb.com> Reviewed-by: Matt DeVillier <matt.devillier@gmail.com>

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.

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().

The new enable_graphics_buffer() will redirect all graphics I/O into an invisible working buffer. To flush (redraw) the buffer to the real screen, call flush_graphics_buffer(). To stop buffering, call disable_graphics_buffer(). BUG=None TEST=Add the enable, flush and disable calls to payload 'depthcharge', built a firmware and boots into Chrome OS recover UI. No more flickering. The average rendering time on x86 platform is 1.2ms.

2020-08-24libpayload: memmove: Don't make expectations of architecture memcpyJulius Werner
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.

Having a pointer inside `libsysinfo` made a mess of it as the pointer would either refer to the original struct inside the coreboot table or to a new struct inside payload space. The latter would be unaffected by a relocation of the payload. Instead of the pointer, we'll always keep a copy of the whole struct, which can be altered on demand without affecting the coreboot table. To align the `video/graphics` driver with the console driver, we also replace `fbaddr` with a macro `FB` that calls phys_to_virt().

Theoretically a horizontal line can also be drawn by calling draw_rounded_box() with dim_rel.x being the line length and dim_rel.y being the line width. However, due to the truncation in integer division when converting relative coordinates to absolute ones, this will potentially produce inconsistent line widths, depending on the value of pos_rel.y. It is guaranteed that draw_line() will produce consistent line widths, regardless of the position of the line. Also, when the thickness argument is zero, this function is able to draw a line with 1-pixel width, which is not achievable by draw_rounded_box().

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).

The QEMU XHCI driver does not implement the Port Change Detect bit in the USBSTS register. As a result no devices are attached without looking at each port individually. Detect this as a quirk based on the QEMU XHCI controller PCI ID, and apply it to the root hub quirk list so it can get used by the generic hub driver to skip this check. With this change an attached USB mass storage device is detected and able to boot when supplied to qemu: -drive if=none,id=usbmsc,format=raw,file=/tmp/disk.img -device qemu-xhci,id-xhci -device usb-storage,bus=xhci.0,drive=usbmsc Change-Id: I6689cb1dbb24c93d45f5c5ef040b713925d07588 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/39839 Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Nico Huber <nico.h@gmx.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2020-04-30libpayload: xhci: Do not memcpy registersJulius Werner
memcpy() is meant to be used on normal memory and often implemented with architecture-specific optimizations to make that as performant as possible. MMIO registers often have special access restrictions that may be incompatible with whatever memcpy() does. For example, on arm64 it uses the LDP (load pair) to load 16 bytes at a time, which makes 4-byte MMIO registers unhappy. This patch removes the caching of the XHCI capreg registers and changes it back to a pointer. The CAP_GET() macro is still accessing a full (non-bitfield) uint32_t at the end so this should still generate a 4-byte access (which was the goal of the original change in CB:39838).

`lib_sysinfo->serial` is a virtual pointer into coreboot tables. It's not valid across relocation. Accessing the wrong value during relocation of FILO resulted in a hang with DEBUG_SEGMENT and UART console enabled. Work around that by caching the whole table entry locally. An alternative would be to revise `sysinfo`, to contain no virtual pointers to anything outside the payload.

2020-04-03libpayload: malloc: Change memcpy() to memmove() in reallocJulius Werner
Our realloc() works (somewhat suboptimally) by free()ing the existing allocation and then reallocating it wherever it fits. If there was free space before the old location, this means the new allocation may be before the old one, and if the free space block is smaller than the old allocation it may overlap. Thus, we should be moving memmove() instead of memcpy() to move the block over. This is not a problem in practice since all our existing memcpy()s are simple iterate and copy front to back implementations which are safe for overlaps when the destination is in front of the source. but it's still the more correct thing to do (in case we ever change our memcpy()s to do something more advanced or whatever).

cbfs_get_handle() and cbfs_get_attr() are both looping over elements to find a particular one. Each element header contains the element's length, which is used to compute the next element's offset. Invalid or corrupted CBFS files could lead to infinite loops where the offset would remain constant across iterations, due to 0-length elements or integer overflows in the computation of the next offset. This patch makes both functions more robust by adding a check that ensure offsets are strictly monotonic. Instead of infinite looping, the functions are now printing an ERROR and returning a NULL value.

2020-02-17libpayload/corebootfb: Fix character buffer relocationNico Huber
The `chars` pointer references the heap which is part of the payload and relocated along with it. So calling phys_to_virt() on it was always wrong; and the virt_to_phys() at its initialization was a no-op anyway, when the console was brought up before relocation. While we are at it, add a null-pointer check.

2020-02-17libpayload: arm64: Keep instruction cache enabled at all timesJulius Werner
This patch makes libpayload enable the instruction cache as the very first thing, which is similar to how we treat it in coreboot. It also prevents the icache from being disabled again during mmu_disable() as part of the two-stage page table setup in post_sysinfo_scan_mmu_setup(). It replaces the existing mmu_disable() implementation with the assembly version from coreboot which handles certain edge cases better (see CB:27238 for details). The SCTLR flag definitions in libpayload seem to have still been copy&pasted from arm32, so replace with the actual arm64 defintions from coreboot.

A function draw_rounded_box() is added to draw a box with rounded corners. In addition, this function is different from draw_box() in 2 ways: - The position and size arguments are relative to the canvas. - This function supports drawing only the border of a box (linear time complexity when the thickness is fixed).
