iabdalkader	b006bb0dff	extmod/vfs_reader: Process pending events during file reads. ... Call `mp_event_handle_nowait()` in the VFS reader buffer refill path so that pending scheduled events (USB task, network poll, etc.) get processed during long-running import/parse/compile operations. Without this, importing a large Python module from the filesystem blocks for too long causing TinyUSB event queue to overflow. For example, on renesas-ra, running a script that imports iperf3 via mpremote run, asserts, most likely due to SOF interrupts not getting processing: queue_event at lib/tinyusb/src/device/usbd.c:382 dcd_event_handler at lib/tinyusb/src/device/usbd.c:1318 dcd_event_sof at lib/tinyusb/src/device/dcd.h:237 dcd_int_handler at tinyusb/src/portable/renesas/rusb2/dcd_rusb2.c:964 <signal handler called> disk_ioctl at extmod/vfs_fat_diskio.c:125 validate at lib/oofatfs/ff.c:3359 f_read at lib/oofatfs/ff.c:3625 file_obj_read at extmod/vfs_fat_file.c:75 mp_stream_rw at py/stream.c:60 mp_reader_vfs_readbyte at extmod/vfs_reader.c:59 next_char at py/lexer.c:174 mp_lexer_to_next at py/lexer.c:713 mp_parse at py/parse.c:1167 Signed-off-by: iabdalkader <i.abdalkader@gmail.com>	2026-02-24 18:46:01 +11:00
Alessandro Gatti	43a4914fe1	tests/micropython: Add a test for checking viper value clobbering. ... This commit introduces a test that should check whether viper load or store operations won't clobber either the buffer address or the index value being used.

Alessandro Gatti	424ae08680	py/asmrv32: Do not clobber index register on viper load/store. ... This commit lets the native emitter preserve the value of the index register when performing register-indexed loads or stores for halfword or word values on RV32. The original code was optimised too aggressively to reduce the generated code's size, using compressed opcodes that alias the target register to one of the operands. In register-indexed load/store operations, the index register was assumed to be allocated somewhere safe, but it was not always the case. To solve this, now all halfword and word register-indexed operations will use REG_TEMP2 to store the scaled index register. The size penalty on generated code varies across operation sizes and enabled extensions: - byte operations stay the same size with or without Zba - halfword operations will be 2 bytes larger without Zba, and will stay the same size with Zba - word operations will be 4 bytes larger without Zba, and 2 bytes larger with Zba There is also a minor firmware footprint increase to hold the extra logic needed for conditional register clobbering, but it shouldn't be that large anyway.

Alessandro Gatti	b46f9f503f	py/asmthumb: Do not clobber index register on viper load/store. ... This commit lets the native emitter preserve the value of the index register when performing register-indexed loads or stores of halfword or word values on Thumb. The original code was optimised too aggressively for a register-starved architecture like Thumb, and the index value in the sequence to generate was assumed to be allocated somewhere safe. This is valid on other architectures, but not on Thumb. To solve this, load operations do clobber a temporary register that should be safe to use, REG_TEMP2, to store the scaled register offset. REG_TEMP2's value is only used within the scope of a single ASM API instruction. Save operations unfortunately use a register that is aliased to REG_TEMP2, since they need to have three values in registers to perform the operation. This means the index register needs to be pushed to the stack before performing the scale + store operation, and then popped from the stack. That's a 4 bytes penalty on each store and a minor speed hit on generated code (plus a minor footprint increase of the firmware image).

Michel Le Bihan	158cbd6065	rp2: Switch all RNG sources from ROSC to pico_rand. ... Replace the custom rosc_random_u8()/rosc_random_u32() implementation with the pico_rand API from the Pico SDK. The RP2040 datasheet notes that ROSC "does not meet the requirements of randomness for security systems because it can be compromised", and the current 8-bit LFSR conditioning is not a vetted algorithm under NIST SP 800-90B. pico_rand uses various hardware RNG sources depending on the available platform (including the RP2350 hardware TRNG) and is officially supported and maintained as part of the Pico SDK. This changes os.urandom(), the mbedTLS entropy source, the PRNG seed, and the lwIP random function to all use pico_rand, and removes the custom ROSC random functions from main.c.

This commit performs a few minor changes to the structures used to store board pin information, in order to reduce the impact on the .rodata section of the firmware of instances of those structures. The pin objects structure ("machine_pin_obj_t") instead has its QSTR variable holder changed from "qstr" to "qstr_short_t", and some elements of that structure have been rearranged to remove enough padding bytes inside structure elements to let the linker allocate less data for instances of that structure.

Convert the stm32 port from the old `MICROPY_EVENT_POLL_HOOK` macro to use the new `mp_event_wait_xxx()` functions in conjunction with `MICROPY_INTERNAL_WFE`. This change should be functionally equivalent to the existing behaivour because `mp_event_wait_ms()` and `mp_event_wait_indefinite()` are equal to `mp_handle_pending(true); __WFI()`, which is what `MICROPY_EVENT_POLL_HOOK` was. Note that the `CYW43_EVENT_POLL_HOOK` macro needed to be overridden, otherwise it would just call `mp_event_handle_nowait()` which would create power hungry busy loops.

Alessandro Gatti	9dcad25de6	py/emitinlinextensa: Add inline assembler support for windowed cores. ... This commit introduces support for writing inline assembler code snippets when targeting Xtensa cores that use register windows (eg. the whole ESP32 family). Opcodes support is still limited to what the ESP8266 supports (as in, LX3 cores opcodes), however each LX core version is guaranteed to support all previous versions' opcodes as well. The ESP32 does not have the inline assembler enabled by default, following the existing expectations when it comes to firmware footprint. Since now emitted functions may have one of two possible exit sequences, the L32I test had to be fixed. It would return the word containing the L32I opcode itself, but the upper 8 bits of the word came from the following opcode - which can change depending on the exit code sequence.

Daniël van de Giessen	71866edc13	py/stream: Use detailed error strings for TLS sockets. ... Both mbedTLS and axTLS have support for producing more detailed error strings. However, these are not used if the error is raised in stream protocol functions (read/write/ioctl). This commit adds support for more detailed error messages from streams. Under the hood it's using a new MP_STREAM_RAISE_ERROR ioctl request to pass the error code back to the stream implementation which can raise a more detailed error. If the ioctl is not implemented, we fall back to the old behaviour and raise an OSError with the error code. Currently the detailed messages are only implemented for TLS sockets since those already had helper functions for raising detailed exceptions, but can be easily implemented in any other stream.

Damien George	ee99014e2a	tests/run-tests.py: Broaden the check for raw REPL failure. ... This is a follow up to 6436f8b93f that catches more cases of a failed raw REPL. If the target device is broken in a certain way then it can have a serial write error instead of just not returning any data. In that case the error raised by `pyboard.py` is "could not enter raw repl: Write timeout", which is slightly different to "could not enter raw repl" (the latter is raised when a serial read fails to return the correct data). The patch here accounts for all cases of a failed raw REPL by using `str.startswith()` instead of a string equality. This can be tested on RPI_PICO_W and RPI_PICO2_W which currently crash in the specific way needed to trigger the write timeout when running the `tests/extmod/socket_badconstructor.py` test. In particular adding the following code to the end of a test (eg `tests/extmod/random_extra.py`) will trigger the issue: import socket try: s = socket.socket(socket.AF_INET, socket.SOCK_RAW, None) except TypeError: pass With the fix here, the `run-tests.py` and `run-natmodtests.py` will abort early if that code is added (prior to the fix they would continue to run all tests and take a long time).
