* libpayload: Add compiler.h to compiler parametersJacob Garber2020-11-081-1/+0
| | | | | | | | | | | | | | | | | | 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.

* Add buffer_to/from_fifo32(_prefix) helpersJulius Werner2019-08-221-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | 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*).

* libpayload: classify all keyboardsMatt Delco2019-05-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | Depthcharge uses the keyboard type to help determine whether it can trust the keyboard for security-sensitive confirmations. Currently it trusts anything except usb, but now there's a need to distrust ec-based ps/2 keyboards that are associated with untrusted ECs. To help facilitate this, coreboot needs to report more details about non-usb keyboards, so this change replaces the current instances of unknown with enum values that distinguish uart and gpio from ec-based keyboards. BUG=b:129471321 BRANCH=None TEST=Local compile and flash to systems with trusted and non-trusted ECs. Confirmed that security confirmation can't be performed via keyboard on a system with an untrusted EC but can still be performed on a system with a trusted EC.

* Make common macros double-evaluation safeJulius Werner2019-04-041-2/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I just got hit by a double-evaluation bug again, it's time to attempt to fix this once more. Unfortunately there are several issues that don't make this easy: - bitfield variables don't support typeof() - local macro variables that shadow others trigger -Werror=shadow - sign warnings with integer literal and unsigned var in typeof-MIN() - ({ statement expressions }) can not be used outside functions - romcc doesn't support any of the fancy GCC/clang extensions This patch tries to address all of them as far as possible with macro magic. We don't have the technology to solve the bitfield and non-function context issues yet (__builtin_choose_expr() still throws a "no statement expression outside a function" error if it's only in the branch that's not chosen, unfortunately), so we'll have to provide alternative macros for use in those cases (and we'll avoid making __ALIGN_MASK() double-evaluation safe for now, since it would be annoying to do that there and having an alignment mask with side effects seems very unlikely). romcc can continue using unsafe versions since we're hopefully not writing a lot of new code for it. Sign warnings can be avoided in literal/variable comparisons by always using the type of the variable there. Shadowing is avoided by picking very explicit local variable names and using a special __COUNTER__ solution for MIN() and MAX() (the only ones of these you're likely to nest). Also add DIV_ROUND_UP() to libpayload since it's a generally quite useful thing to have.

* lib: Unify log2() and related functionsJulius Werner2015-06-051-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a few bit counting functions that are commonly needed for certain register calculations. We previously had a log2() implementation already, but it was awkwardly split between some C code that's only available in ramstage and an optimized x86-specific implementation in pre-RAM that prevented other archs from pulling it into earlier stages. Using __builtin_clz() as the baseline allows GCC to inline optimized assembly for most archs (including CLZ on ARM/ARM64 and BSR on x86), and to perform constant-folding if possible. What was previously named log2f on pre-RAM x86 is now ffs, since that's the standard name for that operation and I honestly don't have the slightest idea how it could've ever ended up being called log2f (which in POSIX is 'binary(2) LOGarithm with Float result, whereas the Find First Set operation has no direct correlation to logarithms that I know of). Make ffs result 0-based instead of the POSIX standard's 1-based since that is consistent with clz, log2 and the former log2f, and generally closer to what you want for most applications (a value that can directly be used as a shift to reach the found bit). Call it __ffs() instead of ffs() to avoid problems when importing code, since that's what Linux uses for the 0-based operation. CQ-DEPEND=CL:273023 BRANCH=None BUG=None TEST=Built on Big, Falco, Jerry, Oak and Urara. Compared old and new log2() and __ffs() results on Falco for a bunch of test values.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | setbits_le32() is not really arch-specific... the arch-specific part of accessing memory is wrapped by readl() and writel(), and the endianness can be accounted for with the right macros. Generalize the definitions, add a be32 version and move them to endian.h so that all platforms can use them. Also include endian.h from libpayload.h so we won't update any payload's old use of the macros (endianness is something useful enough to always have avalable anyway, and shouldn't clash with other things). This also fixes a bug where these macros would only be available if libpayload-config.h had been independently included before. Also fix a bug with readl() macros on all archs where they refused to work on const pointers (which they should). CQ-DEPEND=CL:208712 BUG=None TEST=Stuff still compiles. Built and booted on Storm.

* libpayload: Add remote GDB supportJulius Werner2015-01-091-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the ability to attach a GDB host through the UART to a running payload. Libpayload implements a small stub that can parse and respond to the GDB remote protocol and provide the required primitives (reading/writing registers/memory, etc.) to allow GDB to control execution. The goal of this implementation is to be as small and uninvasive as possible. It implements only the minimum amount of primitives required, and relies on GDB's impressive workaround capabilities (such as emulating breakpoints by temporarily replacing instructions) for the more complicated features. This way, a relatively tiny amount of code on the firmware side opens a vast range of capabilities to the user, not just in debugging but also in remote-controlling the firmware to change its behavior (e.g. through GDBs ability to modify variables and call functions). By default, a system with the REMOTEGDB Kconfig will only trap into GDB when executing halt() (including the calls from die_if(), assert(), and exception handlers). In addition, payloads can manually call gdb_enter() if desired. It will print a final "Ready for GDB connection." on the serial, detach the normal serial output driver and wait for the commands that GDB starts sending on attach. Based on original implementation by Gabe Black <gabeblack@chromium.org>. BUG=chrome-os-partner:18390 TEST=Boot a GDB enabled image in recovery mode (or get it to hit a halt()), close your terminal, execute '<toolchain>-gdb --symbols /build/<board>/firmware/depthcharge_gdb/depthcharge.elf --directory ~/trunk/src/third_party/coreboot/payloads/libpayload --directory ~/trunk/src/platform/depthcharge --directory ~/trunk/src/platform/vboot_reference --ex "target remote <cpu_uart_pty>"' and behold the magic. (You can also SIGSTOP your terminal's parent shell and the terminal itself, and SIGCONT them in reverse order after GDB exits. More convenient wrapper tools to do all this automatically coming soon.)
