      Initial support for ESP32-C6 and ESP32-H2, plus assorted fixes & improvements (#3646) · 4cdebe71
      Jade Mattsson authored
      
      
      * Proof-of-concept multi-type console support via stdio
      
      * Address crashes on linput's use of printf.
      
      On an empty line input, a C3 with UART console would panic while attempting
      to output the new Lua prompt. The backtrace shows a xQueueSemaphoreTake
      with uxItemSize==0 as the panic cause, deep inside the uart driver, invoked
      via vfs_uart and vfs_console layers, from printf.
      Similarly, the printf for outputting a backspace/erase sequence would also
      trigger a panic.
      
      This workaround (of not mixing fflush() with printf) is likely merely hiding
      a deeper issue, but it appears to be consistent. Plus, printf with no args
      and a user-supplied format string is a no-no and should be fixed anyway.
      
      * Work around IDF inconsistency with stdout buffering.
      
      * Increase console task stack size.
      
      Seems on Xtensa it ended up not being enough.
      
      * Switch to single-byte console reads.
      
      * Stop cheating and feed Lua from the right context.
      
      * Work around IDF buffering stdout even when told not to, on ACM consoles.
      
      * Initial build support for esp32c6.
      
      Plus fixup of module selection for a variety of targets.
      
      * Update github actions to node 20 versions.
      
      * Update github build to deal with Lua 5.3 being default.
      
      * Address fatal compiler warning.
      
      Newer IDF toolchain is stricter, and we'd apparently failed to build test
      the Lua-5.1 path for some time.
      
      * Initial build support for esp32h2.
      
      * Upgrade IDF to v5.1.3
      
      * Fix left-over incorrect type in uzlib.
      
      * Avoid null pointer crashes when debugging startup.
      
      * Workaround for using wifi module on S2 with USB-CDC console.

      Switch to IDF-provided VFS and standard `io` module. · a2ba49e3
      Johny Mattsson authored
      The IDF-provided VFS resolves several issues:
      
       - The IDF components having a different view of the (virtual) file system
         compared to the Lua environment.
      
       - RTOS task/thread safety. Our legacy VFS was only ever safe to use
         from the LVM thread, which limited its usability. Upgrading it
         would have effectively required a reimplementation of the IDF VFS,
         which would have been a bigger task with larger on-going maintenance
         issues.
      
       - We're no longer needing to maintain our own SPIFFS component.
      
       - We're no longer needing to maintain our own FATFS component.
      
       - The legacy of the 8266's lack of standard C interface to the file system
         is no longer holding us back, meaning that we can use the standard
         Lua `io` module rather than the cobbled-together swiss army knife
         also known as the file module.
      
      Of course, the downside is that we'll either have to declare a backwards
      breakage in regard to the file module, or provide a Lua shim for the old
      functions, where applicable.
      
      Also included is some necessary integer type fixups in unrelated code,
      which apparently had depended on some non-standard types in either the
      SPIFFS or FATFS headers.
      
      A memory leak issue in the sdmmc module was also found and fixed while
      said module got switched over to the Espressif VFS.
      
      Module documentation has been updated to match the new reality (and I
      discovered in some places it wasn't even matching the old reality).

      Discard old console driver. · fbef7fea
      Johny Mattsson authored
      The IDF provides all we need these days, and the old driver was just
      needlessly conflicting with the IDF settings and setup.
      
      This also simplifies our uart input path as we no longer need to
      duplicate the raw byte handling for when "run_input" is false.
