6a3c2aded6 Fix wait loop and void cast (#24)
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

383ce02442 drivers/rptun/rptun.c and fs/hostfs/hostfs_rpmsg.c: Fix 64-bit build issue in rpmsg driver. 2019-11-03 07:28:17 -06:00

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.

    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).

    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.

be3dd0bac6 fs/: Fix various coding standard issues found while testing tools/nxstyle.c 2019-03-01 15:01:04 -06:00

Fixed coding standard error in several files.  Use of while( is incorrect; a space is required between while and (.  Also ran tools/nxstyle and fix thoses complaints as well in most files.

    Changes to comply with coding standard.  Mostly focused on files with missing space after keyword in if(, switch(, and for(.  Offending files also got changes to comply with tools nxstyle.  If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh.  Still need to fix occurrences of while( with missing space.  There are a lot of them.

9568600ab1 Squashed commit of the following:
This commit backs out most of commit b4747286b1.  That change was added because sem_wait() would sometimes cause cancellation points inappropriated.  But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.

    In the OS, all calls to sem_wait() changed to nxsem_wait().  nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.

    In all OS functions (not libraries), change sem_wait() to nxsem_wait().  This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.

    sched/semaphore:  Add the function nxsem_wait().  This is a new internal OS interface.  It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.

sched/semaphore:  Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable.  Changed all references to sem_post in the OS to nxsem_post().

    sched/semaphore:  Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable.  Changed all references to sem_destroy() in the OS to nxsem_destroy().

    libc/semaphore and sched/semaphore:  Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable.  Changed all references to sem_setprotocol in the OS to nxsem_setprotocol().  sem_getprotocol() was not used in the OS

83cdb0c552 Squashed commit of the following:
libc/semaphore:  Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable.  Changed all references to sem_getvalue in the OS to nxsem_getvalue().

    sched/semaphore:  Rename all internal private functions from sem_xyz to nxsem_xyz.  The sem_ prefix is (will be) reserved only for the application semaphore interfaces.

    libc/semaphore:  Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable.  Changed all references to sem_init in the OS to nxsem_init().

    sched/semaphore:  Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.

    sched/semaphoate:  Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.
