2023-12-13lib/jpeg: Replace decoder with Wuffs' implementationPatrick Georgi
To quote its repo[0]: Wuffs is a memory-safe programming language (and a standard library written in that language) for Wrangling Untrusted File Formats Safely. Wrangling includes parsing, decoding and encoding. It compiles its library, written in its own language, to a C/C++ source file that can then be used independently without needing support for the language. That library is now imported to src/vendorcode/wuffs/. This change modifies our linters to ignore that directory because it's supposed to contain the wuffs compiler's result verbatim. Nigel Tao provided an initial wrapper around wuffs' jpeg decoder that implements our JPEG API. I further changed it a bit regarding data placement, dropped stuff from our API that wasn't ever used, or isn't used anymore, and generally made it fit coreboot a bit better. Features are Nigel's, bugs are mine. This commit also adapts our jpeg fuzz test to work with the modified API. After limiting it to deal only with approximately screen sized inputs, it fuzzed for 25 hours CPU time without a single hang or crash. This is a notable improvement over running the test with our old decoder which crashes within a minute. Finally, I tried the new parser with a pretty-much-random JPEG file I got from the internet, and it just showed it (once the resolution matched), which is also a notable improvement over the old decoder which is very particular about the subset of JPEG it supports. In terms of code size, a QEmu build's ramstage increases from 128060 bytes decompressed (64121 bytes after LZMA) to 172304 bytes decompressed (82734 bytes after LZMA).

2022-09-30util/lint: Update tools that use git to use a libraryMartin Roth
Each of the tools that used git had similar functionality. This combines all of that into a single script that gets sourced by each. This makes maintenance much easier. By doing this and updating each of the scripts to do the correct thing if the script isn't being run in a git repository, it makes them work much better for the releases, which are just released as a tarball, without any attached git repository.

2021-04-06lint: checkpatch: Only exclude specific src/vendorcode/ subdirectoriesJulius Werner
Some of the src/vendorcode/ directories are used to import a whole codebase from somewhere else which uses a completely different coding style. For those directories, excluding them from checkpatch makes sense. However, other directories are simply implementing vendor-specific extensions that were written by coreboot developers specifically for coreboot in coreboot's coding style. Those directories should be covered by checkpatch. This patch narrows the existing blanket exception of src/vendorcode/ to the amd, cavium, intel and mediatek directories (which actually include large amounts of foreign source). The eltan, google and siemens directories (which seem to contain code specifically written for coreboot) will now be covered by checkpatch.

This reverts commit 626ba097a2cd1c87800a2154420829b09803467e. This change was submitted under the incorrect assumption that there was agreement on a coding style change. There wasn't, so while the issue is under discussion we should revert to the previous status quo. Making clang-format honor the line length is a separate issue from changing the line length, and can be reuploaded as a separate CL.
