Damien George	611d8f9ce8	esp32/modsocket: Fix getaddrinfo hints to set AI_CANONNAME. ... Because the `ai_canonname` field is subsequently used. ESP32_GENERIC_S3 (at least) crashes with IDF 5.2.3 without this set. Signed-off-by: Damien George <damien@micropython.org>	2024-11-13 13:35:37 +11:00
Daniël van de Giessen	77406b4240	extmod/network_ppp: Allow stream=None to suspend PPP. ... This allows the stream to be set to `None`, which essentially stops all PPP communication without disconnecting the session. This allows replacing the stream on-the-fly to suspend it, for example to send AT commands to a modem without completely disconnecting and re-establishing the PPP connection: uart = ppp.config('stream') ppp.config(stream=None) uart.write(b'+++') # do some AT commands uart.write(b'ATO\r\n') ppp.config(stream=uart) Any attempted communication by PPP while the stream is not connected will register as simple packet loss to the LwIP stack because we return 0 for any write calls, and protocols like TCP will then automatically handle retrying.

Angus Gratton	df6b40a87f	esp32: Workaround native code execution crash on ESP32-S2. ... Seemingly ESP-IDF incorrectly marks RTC FAST memory region as MALLOC_CAP_EXEC on ESP32-S2 when it isn't. This memory is the lowest priority, so it only is returned if D/IRAM is exhausted. Apply this workaround to treat the allocation as failed if it gives us non-executable RAM back, rather than crashing. This work was funded through GitHub Sponsors.

Angus Gratton	594670e446	esp32/machine_pwm: Restore PWM support for ESP-IDF v5.0.x and v5.1.x. ... The cleanup in 548babf8 relies on some functions not available in older ESP-IDF. Temporarily restore them, until we drop support for ESP-IDF <5.2. PWM functionality should end up the same regardless of ESP-IDF version, and also no different from MicroPython V1.23.

Angus Gratton	82e69df33e	esp32: Apply the LWIP active TCP socket limit. ... This is a workaround for a bug in ESP-IDF where the configuration setting for maximum active TCP sockets (PCBs) is not applied. Fixes cases where a lot of short-lived TCP connections can cause: - Excessive memory usage (unbounded number of sockets in TIME-WAIT). - Much higher risk of stalled connections due to repeated port numbers. The maximum number of active TCP PCBs is reduced from 16 to 12 to further reduce this risk (trade-off against possibility of TIME-WAIT Assassination as described in RFC1337). This is not a watertight fix for the second point: a peer can still reuse a port number while a previous socket is in TIME-WAIT, and LWIP will reject that connection (in an RFC compliant way) causing the peer to stall.

Angus Gratton	05ac69329d	esp32: Fix hang in taskYIELD() on riscv CPUs when IRQs disabled. ... Regression introduced in 337742f. The hang occurs because the esp32 port was calling "from ISR" port-layer functions to set/clear the interrupt mask. FreeRTOS kernel therefore doesn't know the CPU is in a critical section. In taskYIELD() the riscv port layer blocks after yielding until it knows the yield has happened, and would block indefinitely if IRQs are disabled (until INT WDT triggers). Moving to the "public" portENTER_CRITICAL/portEXIT_CRITICAL API means that FreeRTOS knows we're in a critical section and can react accordingly. Adds a regression test for this case (should be safe to run on all ports). On single core CPUs, this should result in almost exactly the same behaviour apart from fixing this case. On dual core CPUs, we now have cross-CPU mutual exclusion for atomic sections. This also shouldn't change anything, mostly because all the code which enters an atomic section runs on the same CPU. If it does change something, it will be to fix a thread safety bug. There is some risk that this change triggers a FreeRTOS crash where there is a call to a blocking FreeRTOS API with interrupts disabled. Previously this code might have worked, but was probably thread unsafe and would have hung in some circumstances. This work was funded through GitHub Sponsors.

The the existing logic was hard to follow, adding this config macro makes it easier to see which USB is in use and to have board definitions that enable/disable different USB levels. This commit also drops (nominal) support for manually setting CONFIG_ESP_CONSOLE_USB_CDC in sdkconfig. No included board configs use this and it didn't seem to work (if secondary console was set to the default USB Serial/JTAG then there is no serial output on any port, and if secondary console was set to None then linking fails.)

Angus Gratton	b6a3aa10f5	esp32: Remove the increased stack limit margin for ESP32-C3. ... The extra limit for C3 dates from 6823514 which added C3 support. Measuring the minimum stack margins that can pass the stress tests I measured 768 bytes for ESP32-S3 and 512 bytes for ESP32-C3 on ESP-IDF V5.2.2 and similar on V5.0.4. i.e. The ESP32-C3 actually needs less stack margin not more! I think the extra margin for ESP32-C3 probably arose from: 1. Some toolchain inefficiency in the IDF V4.x RISC-V compiler codegen, that has since been improved. OR 2. The race condition that was fixed in e3955f42 where sometimes the limit wasn't set correctly at all. This seems to trigger more on C3, presumably some timing artifact, and I'd believe that some binaries might be more susceptible than others due to random factors. OR 3.

Angus Gratton	6565b3cb34	esp32: Fix Python cstack size for bluetooth irq callbacks. ... This value should have been adjusted when the new cstack API was adopted in e3955f421d, as otherwise the stack limit is too small especially on ESP32-C3 where the stack limit was 6144 - 2048 - 2048. Some extra margin is needed for bluetooth irq because invoke_irq_handler() isn't a top-level task function, NimBLE calls through multiple layers first. Measuring this overhead on IDF V5.2.2 (by putting an abort() in invoke_irq_handler() and then measuring the stack size) yielded 672 bytes on ESP32-S3 and 612 bytes on ESP32-C3, similar to the size reported in cd66aa05cf. Sticking with 1024 bytes for added safety margin. This means on Xtensa the total margin for the BLE task stays the same (2048 bytes) as before switching to cstack.

Alessandro Gatti	0b75e180a3	esp32/mphalport: Print debug strings even before the GIL is ready. ... If verbose debugging is enabled there is some stdout output happening before the GIL is ready (for example, GC initialisation), and the code assumed that no string printing occurred before the interpreter was fully initialised. Printing long strings would operate without holding the GIL, which would crash if string output would happen too early in the startup process. This commit addresses that issue, making sure verbose debugging output will work even before the interpreter is fully initialised (as if it is not yet ready there's no GIL to take care of). Also, the threshold that would indicate whether a string is "long" (and thus requiring a GIL release/lock operation) or not was hardcoded to 20 bytes. This commit makes that configurable, maintaining 20 bytes as a default. Fixes issue #15408. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>	2024-08-16 13:45:03 +10:00
