Angus Gratton	1754c587f9	esp32: Fix heap corruption triggered by bluetooth.active(0). ... It seems like at some point Espressif NimBLE team changed nimble_port_init and nimble_port_deinit to manage HCI init internally: https://github.com/espressif/esp-nimble/commit/f8a79b04c9743543b8959727d7 This change is included in all the IDF versions that MicroPython supports. As a result, existing code that called esp_nimble_hci_deinit() explicitly would trigger a use-after-free bug and heap corruption (specifically this calls through to ble_transport_deinit() which calls os_mempool_free(). The second time this writes out to a bunch of memory pools where the backing buffers have already been freed.) Symptoms were intermittent random crashes after de-activating Bluetooth (running multi_bluetooth/ble_gatt_data_transfer.py could sometimes reproduce). Setting Heap Poisoning to Comprehensive in menuconfig caused the bug to be detected every time. This work was funded through GitHub Sponsors.

iabdalkader	a3100be4b2	stm32/boards: Swap FMC banks on ARDUINO_GIGA and ARDUINO_PORTENTA_H7. ... Swap FMC banks to remap the SDRAM bank1 address to 0x60000000. Arduino's M4 firmware uses address 0x60000000 by default. When the elf loader tries to load that it will fail because by default NOR/PSRAM is mapped at that address, not SDRAM bank1. (Note that the region at 0xC0000000 has an XN attribute by default, so switching the M4 firmware address will not work.) Signed-off-by: iabdalkader <i.abdalkader@gmail.com>	2024-07-31 16:47:32 +10:00

Alessandro Gatti	6007f3e206	esp32/mpconfigport: Enable the RV32 emitter for ESP32C3 targets. ... The RV32 code emitter assumed that the arch-specific NLR was used instead of the setjmp/longjmp based NLR code. If the latter NLR provider was chosen, the emitter would allocate space on the stack for the NLR buffer but would not fill it in. This change turns off setjmp()-based NLR and GCREGS for the ESP32C3 target, in favour of more platform-tailored alternatives. As setjmp() NLR is now disabled by default, the RV32 emitter can be safely enabled by default as well for the target in question.

In this situation, `self` in `mp_convert_member_lookup` is the `native_base_init_wrapper_obj`.

Felix Dörre	7fe8f030ee	rp2/lwip_inc: Enable IPv6 per default on rp2 port. ... Having IPv6 support is important, especially for IoT-Devices which might be many, requiring individual IP-addresses. In particular direct access via link-local addresses and having deterministic SLAAC-addresses can be quite convenient. Also in IPv6-only networks or for connecting to IPv6-only services, this is very useful. For the Pico W, there is enough flash and RAM that enabling IPv6 by default is the right choice. Should IPv6 support in a network exist (i.e. there are Router Advertisements), but not provide connectivity, connecting by domain name should not be a problem as DNS will default to return the IPv4-address (if that exists), unless reconfigured at runtime to prefer IPv6. In any case a user can disable obtaining SLAAC-addresses with: <nic>.ipconfig(autoconf6=False) Signed-off-by: Felix Dörre <felix@dogcraft.de>	2024-07-24 14:59:01 +10:00
Angus Gratton	ba98533454	rp2: Stop machine.idle() blocking indefinitely. ... Updates rp2 port to always resume from idle within 1ms max. When rp2 port went tickless the behaviour of machine.idle() changed as there is no longer a tick interrupt to wake it up every millisecond. On a quiet system it would now block indefinitely. No other port does this. See parent commit for justification of why this change is useful. Also adds a test case that fails without this change. This work was funded through GitHub Sponsors.

Angus Gratton	81daba31c5	docs: Specify that machine.idle() returns at least every 1ms. ... A lot of existing code (i.e. micropython-lib lps22h, lcd160cr sensor drivers, lora sync_modem driver, usb-device-hid) calls machine.idle() inside a tight loop that is polling some condition. This reduces the power usage compared to constantly looping, but can be faster than calling a sleep function. However on a tickless port there's not always an interrupt before the condition they are polling for, so it's difficult to restructure this code if machine.idle() doesn't have any upper limit on execution time. This commit specifies an upper limit of 1ms before machine.idle() resumes execution. This is already the case for all ports except rp2. This work was funded through GitHub Sponsors.

Angus Gratton	9db16cfe31	rp2: Fix wakeup from WFE on core1. ... If core1 executes `mp_wfe_or_timeout()` then it needs to receive an interrupt or a SEV to resume execution, but the soft timer interrupt only fires on core 0. This fix adds a SEV to the soft timer interrupt handler. This issue was masked by the issue fixed in the previous commit, as WFE previously wasn't suspending properly.

Angus Gratton	eced9d86a7	rp2: Fix power consumption when sleeping with a timeout. ... Fixes a regression introduced in 3af006efb3 where WFE never blocked in `mp_wfe_or_timeout()` function and would busy-wait instead. This increases power consumption measurably. Root cause is that `mp_wfe_or_timeout()` calls soft timer functions that (after the regression) call `recursive_mutex_enter()` and `recursive_mutex_exit()`. The exit calls `lock_internal_spin_unlock_with_notify()` and the default pico-sdk implementation of this macro issues a SEV which negates the WFE that follows it, meaning the CPU never suspends. See https://forums.raspberrypi.com/viewtopic.php?p=2233908 for more details. The fix in this comment adds a custom "nowait" variant mutex that doesn't do WFE/SEV, and uses this one for PendSV. This will use more power when there's contention for the PendSV mutex as the other core will spin, but this shouldn't happen very often. This work was funded through GitHub Sponsors.

Angus Gratton	337742f6c7	esp32/mpthreadport: Fix uneven GIL allocation between Python threads. ... Explicitly yield each time a thread mutex is unlocked. Key to understanding this bug is that Python threads run at equal RTOS priority, and although ESP-IDF FreeRTOS (and I think vanilla FreeRTOS) scheduler will round-robin equal priority tasks in the ready state it does not make a similar guarantee for tasks moving between ready and waiting. The pathological case of this bug is when one Python thread task is busy (i.e. never blocks) it will hog the CPU more than expected, sometimes for an unbounded amount of time. This happens even though it periodically unlocks the GIL to allow another task to run. Assume T1 is busy and T2 is blocked waiting for the GIL. T1 is executing and hits a condition to yield execution: 1. T1 calls MP_THREAD_GIL_EXIT 2. FreeRTOS sees T2 is waiting for the GIL and moves it to the Ready list (but does not preempt, as T2 is same priority, so T1 keeps running). 3. T1 immediately calls MP_THREAD_GIL_ENTER and re-takes the GIL. 4. Pre-emptive context switch happens, T2 wakes up, sees GIL is not available, and goes on the waiting list for the GIL again. To break this cycle step 4 must happen before step 3, but this may be a very narrow window of time so it may not happen regularly - and quantisation of the timing of the tick interrupt to trigger a context switch may mean it never happens. Yielding at the end of step 2 maximises the chance for another task to run. Adds a test that fails on esp32 before this fix and passes afterwards. Fixes issue #15423.

Damien George	69c25ea865	shared/runtime/pyexec: Make a raised SystemExit always do a forced exit. ... The current situation with SystemExit and soft reset is the following: - `sys.exit()` follows CPython and just raises `SystemExit`. - On the unix port, raising `SystemExit` quits the application/MicroPython, whether at the REPL or in code (this follows CPython behaviour). - On bare-metal ports, raising `SystemExit` at the REPL does nothing, raising it in code will stop the code and drop into the REPL. - `machine.soft_reset()` raises `SystemExit` but with a special flag set, and bare-metal targets check this flag when it propagates to the top-level and do a soft reset when they receive it. The original idea here was that a bare-metal target can't "quit" like the unix port can, and so dropping to the REPL was considered the same as "quit". But this bare-metal behaviour is arguably inconsistent with unix, and "quit" should mean terminate everything, including REPL access. This commit changes the behaviour to the following, which is more consistent: - Raising `SystemExit` on a bare-metal port will do a soft reset (unless the exception is caught by the application). - `machine.soft_reset()` is now equivalent to `sys.exit()`. - unix port behaviour remains unchanged. Tested running the test suite on an stm32 board and everything still passes, in particular tests that skip by raising `SystemExit` still correctly skip.
