Alessandro Gatti	44986b1f04	qemu/riscv64: Add new QEMU RV64 port. ... This adds a QEMU-based bare metal RISC-V 64 bits port. For the time being only QEMU's "virt" 64 bits board is supported, using the lp64 ABI and the RV64IMC architecture. The port's README is also updated to keep track of these changes.

Jeff Epler	f0c6f16b9e	all: Remove Python 2.7 support. ... Python 2.7 has been EOL since January 2020. Ubuntu oldoldlts (Focal Fossa, 20.04) has Python 3.8. Debian oldoldstable (Buster, from 2019) has Python 3.7. RHEL 8 (from 2019) has Python 3.6. It's easier than ever to install a modern Python using uv. Given this, it seems like a fine idea to drop Python 2.7 support. Even though the build is not tested on Python as old as 3.3, I left comments stating that "3.3+" is the baseline Python version. However, it might make sense to bump this to e.g., 3.10, the oldest Python 3 version used during CI. Or, using uv or another method actually test on the oldest Python interpreter that is desirable to support (uv goes back to Python 3.7 easily; in October 2025, the oldest supported Python interpreter version will be 3.10) Signed-off-by: Jeff Epler <jepler@gmail.com>	2025-09-15 14:53:32 +10:00

Angus Gratton	371db85c8e	esp32/machine_uart: Convert machine.UART objects to static instances. ... Makes machine.UART objects static instances (similar to other ports), adds machine_uart_deinit_all() function for cleanup on soft reset. - Fixes the case where the OS-level uart_event_task is leaked (along with 2KB of heap) when a UART object is garbage collected (including after a soft reset). - Fixes hard fault if a previous UART irq() fires after the UART object is garbage collected (including after a soft reset), but before any new UART object is instantiated for the same UART number. - Constructing multiple UART objects for the same UART now returns the same instance multiple times, not different instances. - Was also able to streamline deinit/init to only install the driver once, rather than install-with-defaults/uninstall/reinstall. Alternative would be to add a finaliser, but this is more consistent with how most other UART objects are implemented. This work was funded through GitHub Sponsors.

Angus Gratton	8d5a8892d2	esp32: Add IDF Component Lockfiles to git repo. ... This is recommended by Espressif, and it's the only way to ensure everyone builds the same set of component versions. The awkward part is that updating the ESP-IDF version will churn a line in each of these files (and possibly other changes).

Damien George	c7c0ad222e	alif/tinyusb_port: Fix setting of USB device addr for fast hosts. ... A fast host (eg Mac M4) may request the status for the SET_ADDRESS before TinyUSB gets to process it.

Also has benefit of reducing D/IRAM size, increasing free memory at runtime (167187 to 148584, -18603 bytes).

Daniël van de Giessen	1df5ee12e8	esp32/network_ppp: Stop polling if PPP was disconnected. ... When disconnecting from PPP the modem sends a confirmation. This message is received, like all messages, through the poll() method. lwIP may then immediately call our status callback with code PPPERR_USER to indicate the connection was closed. Our callback then immediately proceeds to free the PCB. Thus, during each new iteration of the loop in poll() we must check if we haven't disconnected in the meantime to prevent calling the pppos_input_tcpip with a PCB that is now NULL.

Damien George	a3f9dec788	py/mpconfig: Enable the sys module at all feature levels by default. ... This is a pretty fundamental module, and even minimal ports like unix and zephyr minimal have it enabled. So, enabled it by default at the lowest feature level. Most things in the `sys` module are configurable, and off by default, so it shouldn't add too much to ports that don't already have it enabled (which is just the minimal port). Also note that `sys` is still disabled on the bare-arm port, to keep that ultra minimal. It means we now have bare-arm without `sys` and the minimal port with `sys`.

Angus Gratton	d8672f4cde	unix: Increase stack sizes if running with sanitizers. ... The specific problem seems to be that the runtime "Python stack frame" function call is several times more expensive in stack usage when running with UBSan on older GCC (observed on gcc 11.4 as used in CI, would get 'RuntimeError: maximum recursion depth exceeded' when running some tests with UBSan enabled.) Other stack usage (i.e. from pushing things on the stack in Python) stays the same. Whatever causes the usage seems to be mostly gone in later GCC versions. Includes a refactor to apply the same stack size multipliers for the default thread stack size same as the main stack size. This goes in a new port-specific header as it depends on macros in misc.h, so can't be in mpconfigport.h. A side effect of this is that the default thread stack size is now doubled on ARM, same as the main stack size. This work was funded through GitHub Sponsors.
