Damien George 469c623bb8 cc3200: Shrink the FreeRTOS heap and place TCB+stack in freed location.
The 16k FreeRTOS heap originally had all TCBs and stacks dynamically
allocated within it (plus semaphores and some other things).  Now that
xTaskCreateStatic is used instead of xTaskCreate, the TCBs and stacks
are allocated statically and no longer use any of the FreeRTOS heap.
Therefore, the FreeRTOS stack can be shrunk by the amount that has been
made static.  Furthermore, the TCBs and stack that are now static should
be placed in the .rtos_heaps section of RAM because this RAM is treated
specially by the bootloader (the bootloader executes from the first 16k
of RAM and loads the firmware into the section starting after the 16k).

After this patch the FreeRTOS heap (ucHeap) is 7200 bytes.  The memory
available for the MicroPython heap is 54936 bytes (including GC overhead).

Damien George e098eac195 cc3200: Start the simplelink spawn task using the static task creator.
In VStartSimpleLinkSpawnTask we change xTaskCreate to xTaskCreateStatic
so that the task is created using statically allocated memory for the TCB
and stack.

This means that xTaskCreate function is no longer needed (the static
version is now used exclusively).

Damien George 5b8e884573 cc3200: Remove .boot section attribute from osi_TaskCreate function.
This function is no longer used.  Having the .boot section attribute
meant that it was included in the firmware regargless of use.  Without
this attribute the linker can remove the function.

Damien George 1d5aa9d245 cc3200: In FreeRTOSConfig.h, comment on configSUPPORT_STATIC_ALLOCATION.
This config variable is now needed regardless of whether threading is
enabled or not.

Damien George fa2ac93c3a cc3200/mpthreadport: Move mem alloc outside the thread_mutex lock.
Otherwise there could be a deadlock, with the GC's mutex and
thread_mutex.

Damien George 757146efe3 cc3200/mpthreadport: Scan more root pointers from thread data. 2016-06-28 11:28:52 +01:00
Damien George 17886828c8 cc3200/gccollect: Use MP_STATE_THREAD(stack_top) to get top of stack. 2016-06-28 11:28:52 +01:00

Damien George 27241293c4 cc3200/mpthreadport: Make mutex statically allocated.
Reduced the need for the FreeRTOS heap to allocate the mutex.

Damien George 0455755296 cc3200: Use xTaskCreateStatic instead of osi_TaskCreate.
This allows to statically allocate the TCB (thread control block) and
thread stack in the BSS segment, reducing the need for dynamic memory
allocation.

Damien George c9520c591b cc3200: Fix call to new exception to be _msg instead of _arg1. 2016-06-28 11:28:51 +01:00
Damien George df95f52583 py/modthread: Allow to properly set the stack limit of a thread.
We rely on the port setting and adjusting the stack size so there is
enough room to recover from hitting the stack limit.

Damien George eef4f13a33 cc3200: Add basic threading capabilities.
Can create a new thread and run it.  Does not use the GIL at this point.

Damien George 9b1c1262dc cc3200: Define our own FreeRTOS heap so it can go in a special segment. 2016-06-28 11:28:50 +01:00
Damien George 5c0fc73f33 cc3200: Update FreeRTOS to v9.0.0.
This is a pristine copy (actually a subset of files) of upstream FreeRTOS
v9.0.0.

Modifications to the previous version of FreeRTOS (v8.1.2) included
addition of __attribute__ ((section (".boot"))) to the following
functions:

    pxPortInitialiseStack
    prvTaskExitError
    prvPortStartFirstTask
    xPortStartScheduler
    vPortSetupTimerInterrupt
    xTaskGenericCreate
    vTaskStartScheduler
    prvInitialiseTCBVariables
    prvInitialiseTaskLists
    prvAllocateTCBAndStack

This attribute will need to be reinstated on a case-by-case basis
because some of the above functions are now removed/changed.

Paul Sokolovsky 07209f8592 all: Rename mp_obj_type_t::stream_p to protocol.
It's now used for more than just stream protocol (e.g. pin protocol), so
don't use false names.

Damien George 70ff7350e7 stmhal, cc3200: Change i2c.scan() method to scan addresses 0x08-0x77.
A standard I2C address is 7 bits but addresses 0b0000xxx and 0b1111xxx
are reserved.  The scan() method is changed to reflect this, along with
the docs.

ports to use the pyhelp_print_obj function.

Jan Čapek d76c65f599 py: Add rules for automated extraction of qstrs from sources.
- add template rule that converts a specified source file into a qstring file

- add special rule for generating a central header that contains all
  extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED
  variable. Each platform appends a list of sources that may contain
  qstrings into a new build variable: SRC_QSTR. Any autogenerated
  prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable.

- remove most qstrings from py/qstrdefs, keep only qstrings that
  contain special characters - these cannot be easily detected in the
  sources without additional annotations

- remove most manual qstrdefs, use qstrdef autogen for: py, cc3200,
  stmhal, teensy, unix, windows, pic16bit:

   - remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.)
   - remove all port specific qstrdefs except for special strings
   - append sources for qstr generation in platform makefiles (SRC_QSTR)

Damien George 5b3f0b7f39 py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure.  So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that).  This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.

Paul Sokolovsky 0e1b5faad5 stmhal, cc3200: Actually implement machine -> umachine module weak link. 2015-12-18 22:22:43 +02:00
Paul Sokolovsky 2eb844e0b4 ports: Rename "machine" module to "umachine".
To let unix port implement "machine" functionality on Python level, and
keep consistent naming in other ports (baremetal ports will use magic
module "symlinking" to still load it on "import machine").

Fixes #1701.

with iBCS2 standard, which jopefully means compatibility with other Unices too).
