github/workflows: Add esp32 to code size report.
Add an esp32 build (specifically ESP32_GENERIC) to the CI code-size check. Multiple new steps must be done to prepare for building esp32, and caching is used to speed up both the install of the IDF and the build process. Signed-off-by: Jeff Epler <jepler@unpythonic.net> |

alif/ospi_flash: Remove workaround for P10_7 OSPI pinmux issue.
P5_6 doesn't have that alt function, and only has 7 alt functions. This workaround was never really needed, it was introduced in DFP because the wrong P10_7 alt function was used, in original DFP sources. This has been removed from DFP starting with 1.3.4, so remove it here also. Signed-off-by: iabdalkader <i.abdalkader@gmail.com> |

alif/Makefile: Enable job server support on Ubuntu LTS.
This commit modifies the Alif port's Makefile to propagate to child make
tasks the number of parallel jobs to run.
On Ubuntu LTS 24.04, building the Alif port passing a parallel jobs
number to make's command line will result in the command emitting this
warning:
make[1]: warning: jobserver unavailable: using -j1. Add '+' to parent
make rule.
And building the two cores' firmware images using one compile job at a
time instead of the number provided to the command line.

alif/Makefile: Do not hardcode the python interpreter name.
This commit fixes a build issue occurring on systems where the Python
3.x interpreter isn't aliased to 'python' but has a different name
(usually `python3').
The main Linux distribution where this occurs is Ubuntu LTS, where the
Python 3.x interpreter is available as 'python3' since at least two
major versions (so since about five years now). MicroPython's makefile
environment setup file ('py/mkenv.mk') already defines a variable called
'$(PYTHON)' that defaults to 'python3', so the Makefile was updated to
use that instead of hardcoding the interpreter name. Without these
changes, building a firmware image on Ubuntu LTS fails with this error:
make: python: No such file or directory
make: *** [Makefile:95: build-ALIF_ENSEMBLE/firmware.toc.bin] Error 127
This also allows overriding the interpreter name to something else if
there's the need to perform tests with different interpreter versions or
the like.

This commit adds byte-swapping macros for 16-, 32-, and 64-bit values. Modern compilers are usually able to detect manual byte/endian swaps and will generate optimised code sequences if they know how to do that. However, in certain situations it may be helpful to let the compiler generate an optimised sequence if it doesn't recognise the pattern. Most compilers provide built-in byte swap operations for 16, 32, and 64 bit values, accessed via "__builtin_bswap<size>", but if those are not available a fallback implementation is provided.

extmod/modopenamp: Rework trace buffer setup procedure.
This commit reworks the setup procedure for the OpenAMP trace buffer, used by the libmetal framework to provide cross-core logging data if needed. Before these changes, the buffer was provided by MicroPython, as a fixed size 128 bytes chunk that was accidentally put into the .rodata section, making it not usable for its intended purpose. Now, a buffer placed in .bss with a default size of 128 bytes is provided by MicroPython unless chosen otherwise. A user-chosen buffer pointer can be provided to MicroPython using the MICROPY_PY_OPENAMP_TRACE_BUF preprocessor definition. If what MicroPython provides by default is fine, the buffer size can be overridden with a new value for the MICROPY_PY_OPENAMP_TRACE_BUF_LEN preprocessor definition instead.

nrf/modules/machine/pin: Reduce footprint of pin structures.
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_obj_t" structure, holding pin information, had an unused
word-sized field ("pull") that isn't used by any of the board
definitions, yet it takes up space in each pin structure being compiled
in the final firmware image.
Images for all available boards were built successfully with this
change, so there should be no unwanted issues arising from shrinking
that structure.

The pin objects structure ("machine_pin_obj_t") instead has its QSTR

of that structure have been rearranged to remove enough padding bytes
inside structure elements to let the linker allocate less data for

This commit performs a minor change to the "pin_af_t" structure, changing the data type used to store alternate function pin name QSTRs in order to have a smaller impact on the .rodata section of the firmware. The data type used to store the QSTR name of the pin is changed from "qstr" to "qstr_short_t", that is able to store the same name string index but in half the size. Other pin-related structures in the port that also store QSTRs do not benefit from a narrower data type, as their members are mostly word-aligned and thus the linker is forced to insert padding bytes between entries.

The implementation uses the object based capabilities, which avoids complication about different flash block sizes. The ROM partition is placed between the text and writable filesystem sections, and the latter size is unchanged. VfsRom sizes are: - NRF51x22: 12K - NRF52832: 128K - NRF52840: 256K - NRF9160: 256K Use frozen `_boot.py` to set up and mount the filesystem, replacing a mix of C-Code and Python code. The mkfs part has been simplified to save code. Tested with Microbit and Arduino Nano Connect. Signed-off-by: Damien George <damien@micropython.org> Signed-off-by: robert-hh <robert@hammelrath.com> |

samd: Add support for VfsRom filesystem for SAMD21 and SAMD51.
The flash driver is update to support the new `mp_vfs_rom_ioctl()` function, and the buffer protocol is added to `samd_flash_type` (it is needed for VfsRom on devices without external flash). For SAMD21, only boards with external SPI flash have VfsRom enabled, due to size constraints. For such boards, the VfsRom filesystem has a size of 12k and is placed at the upper end of the flash. The `onewire`, `ds18x20` and `dht` drivers have been removed from frozen bytecode as they can be placed into the VfsRom files when needed. For SAMD51, the VfsRom filesystem has a default size of 64k for SAMD51x19 and 256K for SAMD51x20. It is placed at the upper end of the flash. For boards with external SPI flash, the code size is reduced from 496K to 432K. If that is not sufficient for some boards or configurations, it can be changed for each board or board variant. Tested with ADAFRUIT_ITSYBITSY_M0_EXPRESS, ADAFRUIT_ITSYBITSY_M4_EXPRESS, SPARKFUN_SAMD51_THING_PLUS, SEEED_XIAO_SAMD21, SAMD_GENERIC_D51X19, and SAMD_GENERIC_D51X20.

mimxrt: Add support for VfsRom filesystem.
The default size for the ROM partition is 256k, and it is placed in flash between the text and writable vfs sections. Its size can be changed in `mpconfigboard.mk` by defining `MICROPY_HW_ROMFS_BYTES` to a different value, but it must not be smaller than a single sector. The MIMXRT1170_EVK and SEEED ARCH MIX ROMFS boards use a larger size of 512kB. ROMFS support is disabled for MIMXRT1050_EVKB due to issues with Hyperflash. The extents of the ROM partition are defined by the linker-level symbols `_micropy_hw_romfs_part0_start` and `_micropy_hw_romfs_part0_size`, following existing ports.

tools/ci.sh: Run natmod tests as part of CI for Unix/RV64.
This commit updates the test procedure for the Unix port targeting the RV64 platform to also run the battery of native modules test that is part of the QEMU port. Unfortunately this required a few changes to the CI setup since the Unix port was still using an older version of Ubuntu LTS than the RISC-V natmods build infrastructure expects. Updating the OS version just for the RV64 Unix target brought a couple of issues when building the code (an extra package is now needed to let FFI build) and running tests (QEMU binfmt support requires a new setup).

unix/mpconfigport: Enable natmod loading for RISC-V builds.
This commit lets the Unix port load native modules when built for both RV32 and RV64. Since RV64 doesn't have a native emitter, the new native code loading configuration settings have been used to allow such a feature. RV32 is fully supported by the native emitter framework but the emitter wasn't enabled for Unix builds (and therefore no natmod support). RV64 builds have been tested on QEMU and on a MilkV-Duo board, and whilst RV32 isn't really tested, its native code loading functionality is routinely tested both on bare-metal QEMU and on microcontroller boards. Since the code for RV64 under Unix and RV32 is essentially the same, having RV64 working is a strong indicator that RV32 will work too. Signed-off-by: Alessandro Gatti <a.gatti@frob.it> |

This commit lets the QEMU port's VIRT_RV64 board load and run native modules, via the appropriate configuration changes in mpconfigport.h. Now the CI test job for the QEMU/RV64 port can also run natmods and see whether they actually work, so the CI tasks script has been updated to bring RV64 to parity with RV32 as far as CI checks go.

This commit adds the ability to compile native modules for the RV64 platform, using "rv64imc" as its architecture name (eg. "make ARCH=rv64imc" should build a RV64 natmod). The rest of 64-bits relocations needed to build a native module are now implemented, and all sample native modules build without errors or warnings. The same Picolibc caveats on RV32 also apply on RV64, thus the documentation was updated accordingly. RV64 native modules are also built as part of the CI process, but not yet executed as the QEMU port is not yet able to load and run them. Signed-off-by: Alessandro Gatti <a.gatti@frob.it> |

tools/mpy_ld.py: Fix handling of R_RISCV_TLSDESC_LOAD_LO12.
This commit fixes handling of the R_RISCV_TLSDESC_LOAD_LO12 RISC-V object file relocation, fixing a couple of mistakes in its usage. The condition check for TLS relocations presence and their rejection when found in object files skipped checking for R_RISCV_TLSDESC_LOAD_LO12 relocations, which is part of the set of unsupported TLS relocations and thus needing an object file rejection. Interestingly, that relocation name constant was actually misspelled in the file - since it was skipped in the list of relocations being checked its wrong name did pass unnoticed until now. This is not a critical change as the linker will raise an error about an unknown relocation type rather than report a more descriptive message to the user, but it's nice to have nonetheless.

This commit fixes the implementation of the R_RISCV_GOT32_PCREL RISC-V relocation type when linking native modules for RV32IMC. The previous implementation of R_RISCV_GOT32_PCREL ended up not being fully updated when the initial RV32 support was checked in. Said relocation was not emitted in the sample natmods that ship with the MicroPython source tree, and since they're the testbed for CI jobs that should check RV32 natmod support, this was not caught. On the other hand, nobody raised an issue about this problem yet, so hopefully it didn't cause much trouble. Signed-off-by: Alessandro Gatti <a.gatti@frob.it> |

This commit makes use of the new native code loading changes to provide a test bed for a target with the native compiler framework available but without no code loading capabilities. mpy-cross already fully disables native code loading, however those changes do not really propagate anywhere outside `py/persistentcode`. Recent changes in the code loading framework actually touch the core code in a few more places, but no default CI target is configured to run with the new native code loading defines switched off. Given that mpy-cross doesn't really need to load code anyway, it is a good target for setting up a configuration that goes a bit deeper when it comes to disabling code loading. Since mpy-cross is built several times during the CI process, it can be repurposed as an early warning system for issues related to these new changes. Normal operation should not be affected in any way. Signed-off-by: Alessandro Gatti <a.gatti@frob.it> |

tests/run-natmodtests.py: Explicitly open prelude file.
This change lets the natmod test runner report status information on session end if a prelude script file is chosen. The script serialises its input data as part of the end of session reporting data, but since the prelude file is not a serialisable object serialisation would fail (it's a file handle as far as the argument container structure is aware). Now the file is explicitly open by the script rather than relying on argparse's file handle argument class wrapper. Signed-off-by: Alessandro Gatti <a.gatti@frob.it> |

This commit lets the nRF port use the new MICROPY_PERSISTENT_CODE_LOAD_NATIVE configuration entry. The nRF port needs a special procedure to allocate memory used to hold executable native code. This functionality was gated behind the presence of a native emitter and thus its inclusion condition had to be updated. Signed-off-by: Alessandro Gatti <a.gatti@frob.it> |

qemu/Makefile: Allow overriding the test natmods list.
This commit modifies the QEMU port makefile to let the user provide their own list of natmods to test as part of "test_natmod". The makefile now will replace the list of natmods to test with the contents of the "TEST_NATMODS" command line variable, so if there's a specific subset of natmods causing problems test runs can be limited to that very subset. "TEST_NATMODS" accepts a whitespace-separated list of natmod names for which there are available matching tests in "tests/extmod" (eg. make test_natmod TEST_NATMODS="btree heapq").

py/emitglue: Flush caches when loading native code without emitters.
This commit forces a data/instruction cache flush after loading native code blocks even if there's no emitter available. Caches flush upon native code load was still tied to the presence of a native emitter, but this assumption is no longer valid due to previous commits decoupling native code loading from code generation availability.

py/persistentcode: Detect the target architecture from compiler defines.
This commit replaces the target architecture definition method, from relying on defines in MicroPython's configuration, to using the host compiler's environment definitions instead. Before these changes the target type was inferred from which kind of native emitter was enabled, since there can be only just one available at all times and it has to be the correct one otherwise generated code would crash the target. However, with the introduction of RV64 there is now a platform without an emitter, and thus RV64 targets would not be able to report their platform via "sys.implementation._mpy". The target is reported only if the interpreter is configured to load external MPY code. Now a series of compile definitions are used to detect the target platform the firmware image is compiled for, making the target definition more accurate and much harder to force the interpreter to report the wrong target architecture due to a misconfiguration. Whilst this is probably not directly affecting user-facing code, some infrastructure components like the testing framework and its associated feature scripts rely on this feature to properly execute test runs. This is also a concern for situations in which loading external binary code is needed but all code generation functions have to be disabled. Signed-off-by: Alessandro Gatti <a.gatti@frob.it> |

py/persistentcode: Decouple native code loading from emitters' presence.
This commit lets the interpreter load MPY files containing native code even if the target platform does not have a native emitter, or if native code generation is disabled. Native code loading has been tied to native code generation being enabled as a discriminant to allow said operation. This blocks native code loading on platforms that could benefit from such a thing but they don't (and probably won't) have a native code generation target written for them (ie. AArch64 and RISC-V 64). This also forces a firmware image to have a full native code compiler present even if it doesn't need to generate anything, as native modules already have all the code they will ever need to load. There is a new configuration setting, MICROPY_PERSISTENT_CODE_LOAD_NATIVE, that if enabled it will allow loading native code modules even if code generation (MICROPY_EMIT_<platform> and MICROPY_EMIT_INLINE_<platform>) is explicitly turned off.

rp2/CMakeLists.txt: Set the appropriate mpy-cross flags on all targets.
This commit lets the RP2 port build system use the appropriate flags to pass to "mpy-cross" when building frozen MPY files as part of the build process. Now all possible variants (RP2040, RP2350/Arm, and RP2350/RV32) have their right flags assigned, falling back the flags set of the RP2040 if a new variant is introduced. Before these changes all variants would use the RP2040 set of flags which may be a bit of an issue when building code for the RP2350 in RV32 mode. Signed-off-by: Alessandro Gatti <a.gatti@frob.it> |

py/asmrv32: Use Zcmp opcodes for function prologues and epilogues.
This commit introduces the possibility of using Zcmp opcodes when generating function prologues and epilogues, reducing the generated code size. With the addition of selected Zcmp opcodes, each generated function can be up to 30 bytes shorter and having a faster prologue and epilogue. If Zcmp opcodes can be used then register saving is a matter of a simple CM.PUSH opcode rather than a series of C.SWSP opcodes. Conversely, register restoring is a single CM.POPRET opcode instead of a series of C.LWSP opcodes followed by a C.JR RA opcode. This should also lead to faster code given that there's only one opcode doing the registers saving rather than a series of them. For functions that allocate less than three locals then the generated code will allocate up to 12 bytes of unused stack space. Whilst this is a relatively rare occurrence for generated native and viper code, inline assembler blocks will probably incur into this penalty. Still, considering that at the moment the only targets that support Zcmp opcodes are relatively high-end MCUs (the RP2350 in RV32 mode and the ESP32P4), this is probably not much of an issue.

py/asmrv32: Reserve a flag for the Zcmp RV32 CPU extension.
This commit performs the necessary changes to handle an additional RV32 CPU extension flag, for the Zcmp extension in this case. The changes are not limited to RV32-only code, as other parts of the tooling need to be modified for this: the testing framework has to be made aware that an extra bit can be set in sys.implementation._mpy and needs to know how it is called, and "mpy-cross" must be able to actually set that flag bit in the first place via the appropriate command line argument.

qemu/Makefile: Allow usage of a custom QEMU binary to run code.
This commit introduces a new optional makefile variable to let the build system know that, when running code, a custom QEMU binary must be used instead of the one provided by the system's PATH. Given that the CI machine won't keep up with QEMU updates unless its base image tracks a new version of QEMU itself, sometimes it is needed to use a custom QEMU build to be able to test new code in an emulated context rather than having to perform on-device testing during development.

tests/run-tests.py: Discover RV32 extension inlineasm tests.
This commit extends the test runner to automatically discover inline
assembler tests for known RV32 extensions, and checks whether to add the
discovered tests to the enabled tests list.
Automatic discovery requires that inline assembler tests for RV32
extensions follow a specific pattern both for filenames and for the
tests' output in case of success. A valid RV32 extension test must
have:
* A code fragment that checks for support of the extension on the
running target in "/tests/feature_check", called
"inlineasm_rv32_<extensionname>.py" that should print the string
"rv32_<extensionname>" if the extension is supported
* A matching expected result file in "/tests/feature_check" called
"inlineasm_rv32_<extensionname>.py.exp" that must contain the string
"rv32_<extensionname>" (without quotes)
* A regular MicroPython test file in "/tests/inlineasm/rv32" called
"asm_ext_<extensionname>.py"
For example, to test the Zba extension, there must be a file called
"/tests/feature_check/inlineasm_rv32_zba.py" that should print the
string "rv32_zba" if the extension is supported, together with a file
called "/test/feature_check/inlineasm_rv32_zba.py.exp" that contains the
string "rv32_zba" in it, and finally there must be a regular MicroPython
test file called "/tests/inlineasm/rv32/asm_ext_zba.py".

py/emitnative: Optimise register clearing.
This commit introduces a new generic ASM API function to clear a register (i.e. clearing all the registers' bits). The native emitter used to perform a XOR operation to clear a given register, but different platform have more optimised method to achieve the same result taking up less space - either for the generated code or for the code generator itself. Arm, RV32, X86, and X64 already had an already optimised generator and generated optimised code. The code generator when build for Thumb takes less space generating a constant immediate move rather than a XOR operation, even though both operations would distill down to a single narrow opcode. On Xtensa the situation is almost the same as Thumb, with the exception that a constant immediate move would take one byte less than a XOR operation.

The SDMMC_HOST_DEFAULT() macro sets slot to SDMMC_HOST_SLOT_1, but this was not being overridden when the user specified a different slot number. This caused SDMMC initialization to fail on chips like ESP32-P4 when trying to use slot 0. This commit ensures the slot number passed to the SDCard constructor is properly assigned to the host configuration structure. Tested on ESP32-P4 with SD card on slot 0.

This commit introduces ESP8266 support for target wiring tests, fixing execution of relevant tests that once failed on that platform. ESP8266 boards need to have GPIO4 and GPIO5 connected together to provide a UART loopback, in order to test whether UART data effectively flows through. The wiring-enabled UART transmission timing test was also updated with measurements compatible with a few ESP8266 test boards. Signed-off-by: Alessandro Gatti <a.gatti@frob.it> |
