Mike Causer 3117fde407 travis: Add esp8266 GENERIC_512K build to CI. 2019-10-10 16:32:25 +11:00
Mike Causer 53a9b45da1 esp8266: Add per-board configs, following other ports.
The specific board can be selected with the BOARD makefile variable.  This
defaults (if not specified) to BOARD=GENERIC, which is the original default
firmware build.  For the 512k target use BOARD=GENERIC_512K.

Jim Mussared fa23033fc4 travis: Add BLE submodules to ESP32 IDF4 build. 2019-10-08 14:52:31 +11:00
Jim Mussared cd8bbf4cfc esp32/boards: Enable BLE by default when building with IDF 4.x. 2019-10-08 14:50:01 +11:00
Jim Mussared 6a9bd1c1ab esp32: Implement BLE using Nimble from IDF 4.x. 2019-10-08 14:50:01 +11:00
Jim Mussared 902bb4ceae stm32: Extract port-specific Nimble implementation.
On other ports (e.g. ESP32) they provide a complete Nimble implementation
(i.e. we don't need to use the code in extmod/nimble). This change
extracts out the bits that we don't need to use in other ports:
 - malloc/free/realloc for Nimble memory.
 - pendsv poll handler
 - depowering the cywbt

Also cleans up the root pointer management.

Damien George 4a6974bea5 stm32/boards/PYBD_SF2: Put nimble library in external QSPI XIP flash.
The BLE stack is not performance critical, so put it in external
memory-mapped flash to save internal flash for other things (like frozen
bytecode).

Damien George f7ddc94166 py/asmxtensa: Add support for Xtensa with windowed registers.
Window-specific asm emit functions are added, along with a new macro option
GENERIC_ASM_API_WIN.

Damien George 306ec5369a py/emitnative: Add support for archs that cannot read executable data.
In which case place the native function prelude in a bytes object, linked
from the const_table of that function.  An architecture should define
N_PRELUDE_AS_BYTES_OBJ to 1 before including py/emitnative.c to emit
correct machine code, then enable MICROPY_EMIT_NATIVE_PRELUDE_AS_BYTES_OBJ
so the runtime can correctly handle the prelude being in a bytes object.

Damien George 3504edc804 py/emitnative: Add support for using setjmp with native emitter.
To enable this feature the N_NLR_SETJMP macro should be set to 1 before
including py/emitnative.c.

Damien George 4107597b84 py/emitnative: Add support for archs with windowed registers.
Such that args/return regs for the parent are different to args/return regs
for child calls.  For an architecture to use this feature it should define
the REG_PARENT_xxx macros before including py/emitnative.c.

Damien George 27fe84e661 tests/basics: Add test for throw into yield-from with normal return.

Damien George 809d89c794 py/runtime: Fix PEP479 behaviour throwing StopIteration into yield from.
Commit 3f6ffe059f implemented PEP479 but did
not catch the case fixed in this commit.  Found by coverage analysis, that
the VM had uncovered code.

Damien George 82c494a97e py/vm: Fix handling of unwind jump out of active finally.
Prior to this commit, when unwinding through an active finally the stack
was not being correctly popped/folded, which resulting in the VM crashing
for complicated unwinding of nested finallys.

This should be fixed with this commit, and more tests for return/break/
continue within a finally have been added to exercise this.

Chris Mason 0096041c99 stm32/{adc,machine_adc}: Change ADC clock and sampling time for F0 MCUs.
STM32F0 has PCLK=48MHz and maximum ADC clock is 14MHz so use PCLK/4=12MHz
to stay within spec of the ADC peripheral.  In pyb.ADC set common sampling
time to approx 4uS for internal and external sources.  In machine.ADC
reduce sample time to approx 1uS for external source, leave internal at
maximum sampling time.

Jim Mussared a09fd04758 py/makeqstrdefs.py: Remove unused blacklist.
As of 7d58a197cf, `NULL` should no longer be
here because it's allowed (MP_QSTRnull took its place).  This entry was
preventing the use of MP_QSTR_NULL to mean "NULL" (although this is not
currently used).

A blacklist should not be needed because it should be possible to intern
all strings.

Fixes issue #5140.

Jim Mussared 4ddd46e6cf docs/develop/qstr.rst: Add documentation for string interning. 2019-10-04 17:13:13 +10:00
Petr Viktorin 25a9bccdee py/compile: Disallow 'import *' outside module level.
This check follows CPython's behaviour, because 'import *' always populates
the globals with the imported names, not locals.

Since it's safe to do this (doesn't lead to a crash or undefined behaviour)
the check is only enabled for MICROPY_CPYTHON_COMPAT.

Fixes issue #5121.

Damien George 26e90a0514 stm32/boards: Enable MICROPY_HW_RTC_USE_LSE on L4 boards.
The previous commit changed the default configuration on L4 MCUs to use
LSI, so configure these boards to use LSE again.

hahmadi 266146ad64 stm32/system_stm32: Support selection of HSE and LSI on L4 MCUs.
This commit adds the option to use HSE or MSI system clock, and LSE or LSI
RTC clock, on L4 MCUs.

Note that prior to this commit the default clocks on an L4 part were MSI
and LSE.  The defaults are now MSI and LSI.

In mpconfigboard.h select the clock source via:

    #define MICROPY_HW_RTC_USE_LSE (0) or (1)
    #define MICROPY_HW_CLK_USE_HSE (0) or (1)

and the PLLSAI1 N,P,Q,R settings:

    #define MICROPY_HW_CLK_PLLSAIN (12)
    #define MICROPY_HW_CLK_PLLSAIP (RCC_PLLP_DIV7)
    #define MICROPY_HW_CLK_PLLSAIQ (RCC_PLLQ_DIV2)
    #define MICROPY_HW_CLK_PLLSAIR (RCC_PLLR_DIV2)

Glenn Ruben Bakke cf383412ef nrf/flash: Update flash driver to use nrfx_nvmc driver.
The the nrfx driver is aware of chip specific registers, while
the raw HAL abstraction is not. This driver enables use of NVMC
in non-secure domain for nrf9160.

Glenn Ruben Bakke 02a8c31eef nrf/temp: Move module configuration guard.
This patch moves the check for MICROPY_PY_MACHINE_TEMP to come
before the inclusion of nrf_temp.h. The nrf_temp.h depends on
the NRF_TEMP_Type which might not be defined for all nRF devices.

Damien George fd9b7efe39 minimal/frozentest.mpy: Update due to change in bytecode. 2019-10-01 12:26:22 +10:00
Damien George c8c0fd4ca3 py: Rework and compress second part of bytecode prelude.
This patch compresses the second part of the bytecode prelude which
contains the source file name, function name, source-line-number mapping
and cell closure information.  This part of the prelude now begins with a
single varible length unsigned integer which encodes 2 numbers, being the
byte-size of the following 2 sections in the header: the "source info
section" and the "closure section".  After decoding this variable unsigned
integer it's possible to skip over one or both of these sections very
easily.

This scheme saves about 2 bytes for most functions compared to the original
format: one in the case that there are no closure cells, and one because
padding was eliminated.

Damien George b5ebfadbd6 py: Compress first part of bytecode prelude.
The start of the bytecode prelude contains 6 numbers telling the amount of
stack needed for the Python values and exceptions, and the signature of the
function.  Prior to this patch these numbers were all encoded one after the
other (2x variable unsigned integers, then 4x bytes), but using so many
bytes is unnecessary.

An entropy analysis of around 150,000 bytecode functions from the CPython
standard library showed that the optimal Shannon coding would need about
7.1 bits on average to encode these 6 numbers, compared to the existing 48
bits.

This patch attempts to get close to this optimal value by packing the 6
numbers into a single, varible-length unsigned integer via bit-wise
interleaving.  The interleaving scheme is chosen to minimise the average
number of bytes needed, and at the same time keep the scheme simple enough
so it can be implemented without too much overhead in code size or speed.
The scheme requires about 10.5 bits on average to store the 6 numbers.

As a result most functions which originally took 6 bytes to encode these 6
numbers now need only 1 byte (in 80% of cases).

Damien George 81d04a0200 py: Add n_state to mp_code_state_t struct.
