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.

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).

2020-03-03payloads/ext/Makefile.inc: Fix SeaBIOS race conditionAngel Pons
For a very long time, SeaBIOS sometimes failed to build when using multiple threads. This known problem has been haunting everyone for a very long time. Until now. Unlike most other payloads, building SeaBIOS results in two files: the SeaBIOS payload itself and SeaVGABIOS. Each file has its own target, and there's a third target called "seabios", which has the same recipe as the SeaBIOS file, which calls `payloads/external/SeaBIOS/Makefile` with a bunch of arguments. In addition, SeaVGABIOS depends on "seabios". When executing serially, if the file of either SeaBIOS or SeaVGABIOS is needed, the SeaBIOS Makefile will be run. This will generate both files, so it is not necessary to run the Makefile more than once. However, when using multiple threads, it can happen that one thread wants to make the SeaBIOS file, while another one wants to make the SeaVGABIOS file, which depends on "seabios". This implies that both threads will execute the SeaBIOS Makefile at about the same time, only to collide when performing git operations. Since git uses a lock file when updating the index, one of the threads will fail to acquire the lock with an error, which will ultimately cause the build to fail. Whenever this happened, manually aborting with Ctrl-C made the build process fail again because of the same error. The only way to get past this problem, other than using one thread, was to let the unfinished jobs complete. The thread that acquired the lock on the SeaBIOS git repository would finish building SeaBIOS, so that target would not need to be remade. When restarting the build, only the target that failed is rebuilt, so it does not collide with any other thread. To address this issue, make the SeaVGABIOS file target depend directly on the SeaBIOS file instead, and remove the duplicate "seabios" target.

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.

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.

2019-12-06endian: Replace explicit byte swapping with compiler builtinJulius Werner
gcc seems to have some stupid problem with deciding when to inline byte swapping functions (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92716). Using the compiler builtin instead seems to solve the problem. (This doesn't yet solve the issue for the read_be32()-family of functions, which we should maybe just get rid of at some point?)

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.
