-* Add changes that need a full description here +### acpi: Add Arm IO Remapping Table structures
-* This section should have full descriptions and can or should have - a link to the referenced commits. +Input Output Remapping Table (IORT) represents the IO topology of an Arm +based system. + +Document number: ARM DEN 0049E.e, Sep 2022 + + +### acpi: Add PPTT support + +This patch adds code to generate Processor Properties Topology Tables +(PPTT) compliant to the ACPI 6.4 specification. + + - The 'acpi_get_pptt_topology' hook is mandatory once ACPI_PPTT is + selected. Its purpose is to return a pointer to a topology tree, + which describes the relationship between CPUs and caches. The hook + can be provided by, for example, mainboard code. + +Background: We are currently working on mainboard code for qemu-sbsa and +Neoverse N2. Both require a valid PPTT table. Patch was tested against +the qemu-sbsa board. + + +### acpi: Add support for WDAT table + +This commit lays the groundwork for implementing the ACPI WDAT (Watchdog +Action Table) table specification. The WDAT is a special ACPI table +introduced by Microsoft that describes the watchdog for the OS. + +Platforms that need to implement the WDAT table must describe the +hardware watchdog management operations as described in the +specification. See “Links to ACPI-Related Documents” +(http://uefi.org/acpi) under the heading “Watchdog Action Table”. + + +### lib/jpeg: Replace decoder with Wuffs' implementation + +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). + +[0] https://github.com/google/wuffs
