This issue-thread shall serve as a collection of breaking changes and otherwise noteworthy information to be part of the Tock 2.1 release notes. This is in addition to a final pass over the merged commits before tagging the final release, so that we don't miss anything important. If you feel like something shall be included, add a comment below.

As discussed on the call today, compiling this list of breaking changes was motivated by an inquiry from @kupiakos. However, the release issue (#3116) tends to get cluttered with testing notes & feedback. Hopefully it'll make discussions around these breaking changes easier to read when they are kept in a separate issue.

I would like to suggest adding a line to the release note/breaking changes:

  • VirtualMuxAlarms now requires the setup() function to be called in board set up code after they are created (e.g. link) after this change

Assuming #3175 stays in, we're breaking the implemented ABI contract for downstream users.

I have absolutely no idea how I got the list of PRs for 2.0. I can't seem to figure out whatever tool I used. Best I've got is using the github command line tool: gh pr list --state merged --limit 5000 which returned this list since the date of the 2.0 release:

This tool gave a slightly prettier output? Still kind of a giant list though.. :/

I went through @ppannuto's list and have a first draft of the 2.1 release notes. Feedback welcome! @ppannuto's list is further included in a drawer below (and GitHub's editor does not cope well with that).

Tock 2.1

Tock 2.1 has seen numerous changes from Tock 2.0. In particular, the new system call interface introduced with Tock 2.0 has been refined to provide more guarantees to processes with respect to sharing and unsharing buffers and upcalls. Other changes include the introduction of a userspace-readable allow system call, support for new HILs and boards, and various other bug-fixes and improvements to code size and documentation.

Breaking Changes

Noteworthy Changes

New HILs

  • hasher
  • public_key_crypto

New Platforms

  • OpenTitan EarlGrey CW310
  • Redboard Red-V B
  • STM32F429I Discovery development board
  • QEMU RISC-V 32-bit "virt" Platform

Deprecated Platforms

  • OpenTitan EarlGrey NexysVideo

Known Issues

This release was tagged despite several known bugs in non-tier-1 boards, so as to avoid delaying the release. These include:

  • Raspberry Pi Pico: process faults when running IPC examples: Raspberry Pi Pico Panic in rot service ipc #3183
  • The cortex-m exception handler does not correctly handle all possible exception entry cases. This is not known to currently manifest on any examples, but could with unlucky timing: Curious Timing Causes Failed Syscall on Cortex-M4 MCU #3109
  • STM32F303 Discovery: adc app runs, but eventually hangs in the app (seems to be caught in the exit loop, but not sure why it gets there)
  • STM32F303 Discovery: kernel panics lead to only a partial printout of the panic message before the board enters a reboot loop
  • weact_f401ccu6: gpio example fails to generate interrupts on the input pin. This board is likely to be deprecated soon anyway, as it is no longer available for sale.

Thanks for the great summary, Leon!

Other changes include the introduction of a read-only allow system call

Read-only allow was in Tock 2.0, perhaps you mean userspace-readable allow?

I updated Leon's comment to fix a couple nits and to add a "Known Issues" section
