3c0b49448a Network Loopback Driver: A configuration option to control packet size.
Historically, the loopback driver used the largest packet size of all enabled link layer protocols.  This permitted packets to be forward via the loopbak device with no major loss of performance.  However, in experimenting with configurations where no other link layer protocols were enabled, this means the loopback packet size was set to the smallest possible size, to the SLIP minimum of 296 bytes.  This resulted in terrible loopback performance.

    This commit adds an option to increase the loopback packet size with the option CONFIG_NET_LOOPBACK_PACKETSIZE.

    The loopback driver packet buffer should be quite large.  The larger the loopback packet buffer, the better will be TCP performance of the loopback transfers.  The Linux loopback device historically used packet buffers of size 16Kb, but that was increased in recent Linux versions to 64Kb.  Those sizes may be excessive for resource constrained MCUs, however.

    The network still enforces the lower limit that is the maximum packet size of all enabled link layer protocols.  But this new option permits the loopback packet size to be increased from that.

    * net/Kconfig:  Adds CONFIG_NET_LOOPBACK_PKTSIZE option
    * include/nuttx/net/netconfig.h:  Assures that the packet size that is used is at least as large as the largest packet size of other link layer protocols.
    * drivers/net/loopback.c:  Use that larger packet size.
    * boards/sim/sim/sim/configs/tcploop/defconfig:  Set the loopback packet size to 1500

6d69439f58 Call xxx_timer_initialize from clock subsystem
Call xxx_timer_initialize from clock subsystem to make timer ready for use as soon as possiblei and revert the workaround:

commit 0863e771a9
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Fri Apr 26 07:24:57 2019 -0600

    Revert "sched/clock/clock_initialize.c:  clock_inittime() needs to be done with CONFIG_SCHED_TICKLESS and clock_initialize should skip clock_inittime() for external RTC case since the RTC isn't ready yet."

    This reverts commit 2bc709d4b9.

    Commit 2bc709d4b9 was intended to handle the case where up_timer_gettime may not start from zero case.  However, this change has the side-effect of breaking every implementation of tickless mode:  After this change the tickless timer structures are used before they are initialized in clock_inittime().  Initialization happens later when up_initialize is called() when arm_timer_initialize().

    Since the tickless mode timer is very special, one solution might be to

    1. Rename xxx_timer_initialize to up_timer_initialize
    2  Move up_timer_initialize to include/nuttx/arch.h
    3.  Call it from clock subsystem instead up_initialize

    Basically, this change make timer initialization almost same as rtc initialization(up_rtc_initialize).

    For now, however, we just need to revert the change.

81f1133174 ELF64 support (#220)
* include: Introduce elf64.h and elf.h

    Added elf64.h for 64bit ELF support and moved common definitions
    from elf32.h to elf.h. Also introduced Elf_xxx to be used in
    common libraries such as binfmt.

  * binfmt, include, modlib, module: Add support for ELF64

    Elf_xxx must be used instead of Elf32_xxx to support ELF64.
    To use ELF64, CONFIG_ELF_64BIT must be enabled.

  * binfmt, modlib: Add support for relocate address

  * arch: risc-v: Add include/elf.h

  * libs: machine: Add risc-v related files.

    NOTE: Currently only supports ELF64

  * boards: maix-bit: Add elf and posix_spawn configurations

  * boards: maix-bit: Add support for module configuration

2def8035db sched/sched/sched_getcpu.c: Implement non-standard interface.
If SMP is enabled this function will return the number of the CPU that the thread is running on.  This is non-standard but follows GLIBC if __GNU_SOURCE is enabled.  The returned CPU number is, however, worthless since it returns the CPU number of the CPU that was executing the task when the function was called.  The application can never know the true CPU number of the CPU tht it is running on since that value is volatile and change change at any time.

    Net cleanup (#17)

    * Fix the semaphore usage issue found in tcp/udp

    1. The count semaphore need disable priority inheritance
    2. Loop again if net_lockedwait return -EINTR
    3. Call nxsem_trywait to avoid the race condition
    4. Call nxsem_post instead of sem_post

    * Put the work notifier into free list to avoid the heap fragment in the long run.  Since the allocation strategy is encapsulated internally, we can even refine the implementation later.

    * Network stack shouldn't allocate memory in the poll implementation to avoid the heap fragment in the long run, other modification include:

    1. Select MM_IOB automatically since ICMP[v6] socket can't work without the read ahead buffer
    2. Remove the net lock since xxx_callback_free already do the same thing
    3. TCP/UDP poll should work even the read ahead buffer isn't enabled at all

    * Add NET_ prefix for UDP_NOTIFIER and TCP_NOTIFIER option to align with other UDP/TCP option convention

    * Remove the unused _SF_[IDLE|ACCEPT|SEND|RECV|MASK] flags since there are code to set/clear these flags, but nobody check them.

87cf5c58ae Correct some problems with network timed events when there are multiple network devices in the configuration.
Squashed commit of the following:

Author: Gregory Nutt <gnutt@nuttx.org>

    Ran nxstyle against many of the affected files.  But this job was too big for today.  Many of the network drivers under arch are highly non-compiant and generate many, many faults from nxstyle.  Those will have to be visited again another day.

Author: Xiang Xiao <xiaoxiang@xiaomi.com>

    This effects all network drivers as well as timing related portions of net/: devif_poll_tcp_timer shouldn't be skipped in the multiple card case.  devif_timer will be called multiple time in one period if the multiple card exist, the elapsed time calculated for the first callback is right, but the flowing callback in the same period is wrong(very short) because the global variable g_polltimer is used in the calculation.  So let's pass the delay time to devif_timer and remove g_polltimer.
