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.

2020-08-24libpayload: Cache copy of `cb_framebuffer` structNico Huber
Our AArch64 code supports dynamic framebuffer allocation which makes it necessary to change the framebuffer information during runtime. 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().

2020-08-24libpayload: Cache physical cbmem console addressNico Huber
Same as with other consoles and drivers that cache an address outside the payload (e.g. video/corebootfb), we should store the physical address, so we can derive the virtual address on demand. This makes it save to use the address across relocations. As a first step in migrating `libsysinfo` to `uintptr_t`, we also switch to the physical address there.

2020-07-23libpayload: cbgfx: Add draw_line()Yu-Ping Wu
Add a function draw_line() to draw either a horizontal or vertical line segment. 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().

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).

That's a bad idea, though, since 0xffffffff when interpreted as an int32_t would become a negative number. We need to always shift one more than the current code does to get a safe reduction.

2020-05-01lp/drivers/usb: Add quirk for QEMU XHCI root hubDuncan Laurie
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.

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.

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.

2019-12-05arm64: Bump exception stack size to 2KBJulius Werner
To avoid trampling over interesting exception artifacts on the real stack, our arm64 systems switch to a separate exception stack when entering an exception handler. We don't want that to use up too much SRAM so we just set it to 512 bytes. I mean it just prints a bunch of registers, how much stack could it need, right? Quite a bit it turns out. The whole vtxprintf() call stack goes pretty deep, and aarch64 generally seems to be very generous with stack space. Just the varargs handling seems to require 128 bytes for some reason, and the other stuff adds up too. In the end the current implementation takes 1008 bytes, so bump the exception stack size to 2K to make sure it fits.

Some broken USB mass storage devices send another zero-length packet at the end of the data part of a transfer if the amount of data was evenly divisible by the packet size (which is pretty much always the case for block reads). This packet will get interpreted as the CSW and screw up the MSC state machine. This patch works around this issue by retrying the CSW transfer when it was received as exactly 0 bytes. This is the same mitigation the Linux kernel uses and harmless for correctly behaving devices. Also tighten validation of the CSW a little, making sure we verify the length before we read any fields and checking the signature in addition to the tag.

2019-08-22Add buffer_to/from_fifo32(_prefix) helpersJulius Werner
Many peripheral drivers across different SoCs regularly face the same task of piping a transfer buffer into (or reading it out of) a 32-bit FIFO register. Sometimes it's just one register, sometimes a whole array of registers. Sometimes you actually transfer 4 bytes per register read/write, sometimes only 2 (or even 1). Sometimes writes need to be prefixed with one or two command bytes which makes the actual payload buffer "misaligned" in relation to the FIFO and requires a bunch of tricky bit packing logic to get right. Most of the times transfer lengths are not guaranteed to be divisible by 4, which also requires a bunch of logic to treat the potential unaligned end of the transfer correctly. We have a dozen different implementations of this same pattern across coreboot. This patch introduces a new family of helper functions that aims to solve all these use cases once and for all (*fingers crossed*).

2019-07-23libpayload/libc: Correct strlcat return valueJacob Garber
The documented return value for strlcat is horribly wrong, as is the return value itself. It should not return the number of appended bytes, but rather the length of the concatenated string. From the man page: The strlcpy() and strlcat() functions return the total length of the string they tried to create. For strlcpy() that means the length of src. For strlcat() that means the initial length of dst plus the length of src. While this may seem somewhat confusing, it was done to make truncation detection simple. This change is more likely to fix existing code than break it, since anyone who uses the return value of strlcat will almost certainly rely on the standard behaviour rather than investigate coreboot's source code to see that we have a quirky version.
