8b92305265 This commit brings in the drivers needed to support OpenAMP. These changes were ported from https://github.com/FishsemiCode/nuttx. The current state: Most drivers do now compile but are not yet verfied.
This port was effort of a number of people, I rather arbitrarily gave authorship to Guiding Li because he has the largest number of fundamental quashed commits from the Xiamoi repository.

Squashed commit of the following:

Author: Xiang Xiao <xiaoxiang@pinecone.net>
    include/nuttx/b2c.h and libx/libc/string:  Add non-standard string functions to deal with cases where there are more than 8-bits in a type char.

Author: Gregory Nutt <gnutt@nuttx.org>
    Fix several build issues/missing definitiona needed for OpenAMP build in drivers/.
    Add OpenAMP code has been reviewed and ran through tools/nxstyle (with all reports accounted for).

Author: Xiang Xiao <xiaoxiang@xiaomi.com>
    tools/:  Fix the minor issue in Makefile

Author: Gregory Nutt <gnutt@nuttx.org>
    drivers/rptun/rptun.c:  Review for coding standard.  Run against tools/nxstyle.
    tools/LibTargets.mk:  Fix some TABs that were turned into spaces by a copy-paste.
    fs/hostfs:  Add configure and build support for hostfs RPC.
    drivers/timer:  Add configure and build support for syslog RTC.
    drivers/syslog:  Add configure and build support for syslog RPC.
    drivers/serial:  Add configure and build support for serial RPC.
    Kconfig, tools/*.mk. openamp/:  Add basic OpenAMP build support.
    drivers/rptun:  Add configure and build support for OpenAMP tunnel drivers.
    drivers/net:  Update Make.defs and Kconfig for OpenSDA support.
    Remove drivers/clk/clk-rpmsg.c drivers/power/rpmsg_regulator.c.  These depend on upstreaming support for a new subsystem based on the clk/regulator is model from Linux.  Removed because we want to separate the activities.  We will just try to get the basic OpenAMP support in place for now.
    Remove drivers/misc/misc_rpmsg.c and include/nuttx/misc/misc_rpmsg.h.  These are specific to the Xiaomi application.

fae7e63479 We have ported NuttX on Renesas RX65N Micro-controller. This port includes following interfaces
1. Serial (UART) driver (13 ports)
2. Ethernet driver

This port is provided on two boards
1. RSK RX65N-2MB
2. GR-Rose

The port is built on Cygwin environment.

As part of this port, we have created two documents
1. Readme.txt for each board
2. User manual to provide information about development environment setup
Both these documents are placed under
1. /boards/renesas/rx65n/rx65n-grrose
2. /boards/renesas/rx65n/rx65n-rsk2mb

We have run 'nxstyle' for coding guidelines and 'ostest' for testing NuttX features on test platform.
We have shared the log with no errors as confirmation of valid port.

a7fd58c4db Squashed commit of the following:
many locations:  Change occurences of open() followed by file_detach() to file_open().  Change most non-controversion calls to open() to nx_open().

    fs/inode/fs_fileopen.c:  Flesh out file_open() with some interim, placeholder logic.

    fs/inode/fs_fileopen.c:  Add a framework for a file_open() implementation (no real logic in place yet).

    fs/vfs/fs_open.c:  Add nx_open() which is the same as open() except that it does not create a cancellation point nor does it modify the errno variable.

a7265d71c6 This commit adds support for default signal actions for SIGSTOP, SIGSTP, and SIGCONT.
Squashed commit of the following:

    Add procfs support to show stopped tasks.  Add nxsig_action() to solve a chicken and egg problem:  We needed to use sigaction to set default actions, but sigaction() would refuse to set actions if the default actions could not be caught or ignored.

    sched/signal:  Add configuration option to selectively enabled/disable default signal actions for SIGSTOP/SIGSTP/SIGCONT and SIGKILL/SIGINT.  Fix some compilation issues.

    sched/sched:  Okay.. I figured out a way to handle state changes that may occur while they were stopped. If a task/thread was already blocked when SIGSTOP/SIGSTP was received, it will restart in the running state.  I will appear that to the task/thread that the blocked condition was interrupt by a signal and returns the EINTR error.

    sched/group and sched/sched:  Finish framework for continue/resume logic.

    sched/signal:  Roughing out basic structure to support task suspend/resume

c0d234a474 Squashed commit of the following:
drivers/serial/Kconfig:  It is no longer necessary to restrict Ctrl-C handling to the FLAT build

    sched/signal:  Add a new configuration option to select signal default actions, separate handling of signal default actions from both task startup logic and from the serial TTY Ctrl-C logic.  Add a signal set in the group structure to keep track of what signals have been set to the default action.  In dispatching signals in PROTECTED or KERNEL mode, use this signal set to determine if the default signal handler is attached and dispatch the signal in kernel mode for the default actions.

f3392e0a6c drivers/serial: Add a timeout to uart_tcdrain(). Even if tcflush() is used to discard buffered data, the close() can still hang if (a) hardware flow control is enabled, (b) CTS == 1, and (c) there is data stuck in the hardware Tx FIFO. tcflush() does not currently clear the MCU serial drivers' hardware Tx FIFOs. This is a workaround for that. 2018-05-27 11:39:34 -06:00

759e510c28 Per Matias Edlund: I recently used the tcflush function and found that it failed with ENOTTY. The reason is that the TCFLSH case in the function uart_ioctl in the file drivers/serial/serial.c does not update the ret value." On success, the TCFLSH IOCTL logic needs to explicitly set the return value (ret) to zero. 2018-03-26 13:54:47 -06:00
