Paul Sokolovsky 6ddcfe68b8 unix/Makefile: Allow to override/omit pthread lib name.
For example, on Android, pthread functions are part of libc, so LIBPTHREAD
should be empty.

Damien George a07e56cbd8 tests/basics/class_getattr: Remove invalid test for __getattribute__.
Part of this test was trying to test some functionality of __getattribute__
but this method name was misspelt so it wasn't doing anything useful.
Fixing the typo in this name makes the test fail because MicroPython
doesn't support user defined __getattribute__ methods.  So this part of the
test is removed.  The remaining tests are modified slightly to make it
clearer what they are testing.

Damien George 7eb29c2000 py/objtype: Remove comment about catching exc from user __getattr__.
Any exception raised in a user __getattr__ should be propagated out.  A
test is added to verify these semantics.

Paul Sokolovsky 0c18633ea9 unix/modusocket: Finish socket.settimeout() implementation.
1. Return correct error code for non-blocking vs timed out socket
(POSIX returns EAGAIN for both, we want ETIMEDOUT in case of timed
out socket). To achieve this, blocking/non-blocking flag is added
to the mp_obj_socket_t, to avoid issuing fcntl() syscall each time
EAGAIN occurs. (mp_obj_socket_t used to be 8 bytes, having some room
in a standard 16-byte alloc block.)

2. Handle socket.settimeout(0) properly - in Python, that means
non-blocking mode, but SO_RCVTIMEO/SO_SNDTIMEO of 0 is infinite
timeout.

3. Overall, make sure that socket.settimeout() call switches blocking
state as expected.

Damien George 0f6f86ca49 stm32/usbd_cdc_interface: Refactor USB CDC tx code to not use SOF IRQ.
Prior to this commit the USB CDC used the USB start-of-frame (SOF) IRQ to
regularly check if buffered data needed to be sent out to the USB host.
This wasted resources (CPU, power) if no data needed to be sent.

This commit changes how the USB CDC transmits buffered data:
- When new data is first available to send the data is queued immediately
  on the USB IN endpoint, ready to be sent as soon as possible.
- Subsequent additions to the buffer (via usbd_cdc_try_tx()) will wait.
- When the low-level USB driver has finished sending out the data queued
  in the USB IN endpoint it calls usbd_cdc_tx_ready() which immediately
  queues any outstanding data, waiting for the next IN frame.

The benefits on this new approach are:
- SOF IRQ does not need to run continuously so device has a better chance
  to sleep for longer, and be more responsive to other IRQs.
- Because SOF IRQ is off, current consumption is reduced by a small amount,
  roughly 200uA when USB is connected (measured on PYBv1.0).
- CDC tx throughput (USB IN) on PYBv1.0 is about 2.3 faster (USB OUT is
  unchanged).
- When USB is connected, Python code that is executing is slightly faster
  because SOF IRQ no longer interrupts continuously.
- On F733 with USB HS, CDC tx throughput is about the same as prior to this
  commit.
- On F733 with USB HS, Python code is about 5% faster because of no SOF.

As part of this refactor, the serial port should no longer echo initial
characters when the serial port is first opened (this only used to happen
rarely on USB FS, but on USB HS is was more evident).

Damien George 53ccbe6cec stm32/usbd_cdc_interface: Handle disconnect IRQ to set VCP disconnected.
pyb.USB_VCP().isconnected() will now return False if the USB is
disconnected after having previously been connected.

Damien George de71035e02 py/emitnative: Put None/False/True in global native const table.
So these constant objects can be loaded by dereferencing the REG_FUN_TABLE
pointer instead of loading immediate values.  This reduces the size of
generated native code (when such constants are used), and means that
pointers to these constants are no longer stored in the assembly code.

Damien George 6c6050ca43 py/emitnative: Push internal None rather than const obj where possible.
This shifts the work of loading the constant None object on to
load_reg_stack_imm(), making the handling of None more centralised.

Damien George 175739cd37 py/emitnative: Consolidate use of stacked immediate values to one func.
This commit adds the helper function load_reg_stack_imm() which deals with
constant immediate values and converting them to Python objects if needed.

Otherwise there is really nothing that can be done, it can't be unlocked by

Damien George 6bda951d4d py/emitnative: Remove unused ptr argument from ASM_CALL_IND macro. 2018-10-13 15:16:33 +11:00
Damien George 25571800fc py/asmthumb: Remove unused fun_ptr arg from asm_thumb_bl_ind function. 2018-10-13 15:16:33 +11:00
Damien George 5f1dd5b86b py/asmarm: Simplify asm_arm_bl_ind to only load via index, not literal.
The maximum index into mp_fun_table is currently less than 1024 and should
stay that way to keep things efficient for all architectures, so there is
no need to handle loading the pointer directly via a literal in this
function.

Damien George 006671056d py/emitnative: Load native fun table ptr from const table for all archs.
All architectures now have a dedicated register to hold the pointer to the
native function table mp_fun_table, and so they all need to load this
register at the start of the native function.  This commit makes the
loading of this register uniform across architectures by passing the
pointer in the constant table for the native function, and then loading the
register from the constant table.  Doing it this way means that the pointer
is not stored in the assembly code, helping to make the code more portable.

Damien George 355eb8eafb py/asmx86: Change indirect calls to load fun ptr from the native table.
Instead of storing the function pointer directly in the assembly code.
This makes the generated code more independent of the runtime (so easier to
relocate the code), and reduces the generated code size.

Damien George b7c6f859d0 py/asmx86: Change stack management to reference locals by esp not ebp.
The esp register is always a fixed distance below ebp, and using esp to
reference locals on the stack frees up the ebp register for general purpose
use (which is important for an architecture with only 8 user registers).

Damien George 8941c63290 py/asmx64: Change stack management to reference locals by rsp not rbp.
The rsp register is always a fixed distance below rbp, and using rsp to

Glenn Ruben Bakke 11bc38d55f nrf/bluetooth: Set GAP_ADV_MAX_SIZE to 31 (s132/s140).
For s132 and s140, GAP_ADV_MAX_SIZE was currently set to
BLE_GATT_ATT_MTU_DEFAULT, which is 23. The correct value
should have been 31, but there are no define for this in
the s132/s140 header files as for s110.

Updating define in ble_drv.c to the correct value of 31.

Andrew Leech 338635ccc6 stm32/main: Add configuration macros for board to set heap start/end.
The macros are MICROPY_HEAP_START and MICROPY_HEAP_END, and if not defined
by a board then the default values will be used (maximum heap from SRAM as
defined by linker symbols).

As part of this commit the SDRAM initialisation is moved to much earlier in
main() to potentially make it available to other peripherals and avoid
re-initialisation on soft-reboot.  On boards with SDRAM enabled the heap
has been set to use that.

stijn 02ca8d4674 windows/msvc: Implement file/directory type query.
Add some more POSIX compatibility by adding a d_type field to the
dirent structure and defining corresponding macros so listdir_next
in the unix' port modos.c can use it, end result being uos.ilistdir
now reports the file type.

Paul Sokolovsky 18f45d2e23 extmod/moductypes: Remove BITFIELD from aggregate types enum.
This value is unused. It was an artifact of early draft design, but
bitfields were optimized to use scalar one-word encoding, to allow
compact encoding of typical multiple bitfields in MCU control
registers.

Paul Sokolovsky d251f26688 docs/uselect: Describe more aspects of poll.register/modify behavior.

Paul Sokolovsky 6ef783527d tests/uselect_poll_basic: Add basic test for uselect.poll invariants.

Damien George 69e7903904 py/obj.h: Use uint64_t instead of mp_int_t in repr-D MP_OBJ_IS_x macros.
This follows how it's already done in MP_OBJ_IS_OBJ: the objects are
considered 64-bit unsigned ints for the purpose of bitwise manipulation.

Damien George b3e013f60e docs: Unify all the ports into one set of documentation.
With this commit there is now only one entry point into the whole
documentation, which describes the general MicroPython language, and then
from there there are links to information about specific platforms/ports.

This commit doesn't change content (almost, it does fix a few internal
links), it just reorganises things.

Damien George 5cc9517fc5 tests/run-tests: Enabled native tests that pass now that yield works. 2018-10-01 13:31:11 +10:00
Damien George cc2bd63c57 py/emitnative: Implement yield and yield-from in native emitter.
This commit adds first class support for yield and yield-from in the native
emitter, including send and throw support, and yields enclosed in exception
handlers (which requires pulling down the NLR stack before yielding, then
rebuilding it when resuming).

This has been fully tested and is working on unix x86 and x86-64, and
stm32.  Also basic tests have been done with the esp8266 port.  Performance
of existing native code is unchanged.

Damien George 8fec6f5434 py/emitnative: Reorder native state on C stack so nlr_buf_t is first.
The nlr_buf_t doesn't need to be part of the Python value stack (as it was
before this commit), it's simpler to have it separated as auxiliary state
that lives on the C stack.  This will help adding yield support because in
that case the nlr_buf_t and Python value stack live in separate memory
areas (C stack and heap respectively).
