Chris Webb	ccc954256f	tests: Generalise rp2 timer test into a cross-port test. ... Now all ports with machine.Timer except nrf support both hard and soft callbacks, generalise tests/ports/rp2_machine_timer.py into tests/extmod/machine_timer.py. There is an existing machine_soft_timer.py which varies period= and covers the nrf port but skips esp32/esp8266 because they don't support software timers. In our new test, we try varying freq= instead of period=, and cover esp32/esp8266 (with a fixed choice of hardware timer) but skip nrf because it doesn't support hard= or freq=. Add a check that the heap is locked (so allocation fails) in hard callbacks and it is unlocked (so allocation succeeds) in soft callbacks, to ensure we're getting the right kind of callback, not falling back to the default.

Damien George	b3c8ed6c33	tests/ports/rp2: Decrease test lower bound for thread lightsleep time. ... This makes the rp2-specific lightsleep test more lenient, so it passes. This test was added in PR #16454 / 69993daa5c and even back then it did not pass reliably on RP2040. The issue is that threads can race each other to enter lightsleep mode, and when one of them actually stops the CPU clock the other thread is stopped as well. Depending on whether the other thread was just entering or just exiting lightsleep itself, the total duration of all sleeps can vary and can be as small as 2*T. Therefore, adjust the minimum to allow 2*T. `machine.lightsleep()` is anyway 1) specified only to wait at most the given time; and 2) not well specified when multiple threads call it at the same time. So it seems OK to make the test more lenient. Work done in collaboration with @projectgus. Signed-off-by: Damien George <damien@micropython.org>	2025-09-08 11:07:36 +10:00

Angus Gratton	69993daa5c	rp2/modmachine: Add mutual exclusion for machine.lightsleep(). ... There's no specified behaviour for what should happen if both CPUs call `lightsleep()` together, but the latest changes could cause a permanent hang due to a race in the timer cleanup code. Add a flag to prevent hangs if two threads accidentally lightsleep, at least. This allows the new lightsleep test to pass on RPI_PICO and RPI_PICO2, and even have much tighter time deltas. However, the test still fails on wireless boards where the lwIP tick wakes them up too frequently. This work was funded through GitHub Sponsors.

Damien George	00a0cd70f5	tests/ports/rp2: Tune rp2.DMA test so it runs in all configurations. ... Changes in this commit: - Allow the DMA instance to be any instance, not just DMA(0); eg WLAN may be using DMA(0). - Make the DMA timing test run a little faster by preloading `dma.active`. - Run the DMA timing test 10 times and take the average time taken as the test result, to eliminate any big effects of caching. - Change the expected time to `range(30, 80)` to cover RP2040, RP2350, RISC-V variants, and both bytecode and native emitter. - Add a `sleep_ms(1)` after waiting for the IRQ to fire, so that any scheduled code gets a chance to run when the test is compiled with the native emitter. With these changes this test passes reliably on RPI_PICO, RPI_PICO_W, RPI_PICO2, RPI_PICO2_W, RPI_PICO2-RISCV and RPI_PICO2_W-RISCV, in both bytecode and native emitter mode, with and without WLAN enabled.

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	068d9bf2cf	rp2: Fix USB PLL glitch during wake from light sleep. ... Follow-up to a84c7a0ed9, this commit works most of the time but has an intermittent bug where USB doesn't resume as expected after waking from light sleep. Turns out waking calls clocks_init() which will re-initialise the USB PLL. Most of the time this is OK but occasionally it seems like the clock glitches the USB peripheral and it stops working until the next hard reset. Adds a machine.lightsleep() test that consistently hangs in the first two dozen iterations on rp2 without this fix. Passed over 100 times in a row with this fix. The test is currently rp2-only as it seems similar lightsleep USB issues exist on other ports (both pyboard and ESP32-S3 native USB don't send any data to the host after waking, until they receive something from the host first.)
