chao an 6ee9ec7656 build: add initial cmake build system 1. Update all CMakeLists.txt to adapt to new layout 2. Fix cmake build break 3. Update all new file license 4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose) ------------------ How to test From within nuttx/. Configure: cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja (or full path in custom board) : cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja This uses ninja generator (install with sudo apt install ninja-build). To build: $ cmake --build build menuconfig: $ cmake --build build -t menuconfig -------------------------- 2. cmake/build: reformat the cmake style by cmake-format https://github.com/cheshirekow/cmake_format $ pip install cmakelang $ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done $ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done Co-authored-by: Matias N <matias@protobits.dev> Signed-off-by: chao an <anchao@xiaomi.com>		2023-07-08 13:50:48 +08:00

fs/procfs README
================

  This is a tiny procfs file system that allows read-only access to a few
  attributes of a task or thread.  This tiny procfs fs file system can be
  built into the system by enabling:

    CONFIG_FS_PROCFS=y

  It can then be mounted from the NSH command like like:

    nsh> mount -t procfs /proc

Example
=======

  NuttShell (NSH) NuttX-6.31
  nsh> mount -t procfs /proc

  nsh> ls /proc
  /proc:
   0/
   1/

  nsh> ls /proc/1
  /proc/1:
   status
   cmdline

  nsh> cat /proc/1/status
  Name:       init
  Type:       Task
  State:      Running
  Priority:   100
  Scheduler:  SCHED_FIFO
  SigMask:    00000000

  nsh> cat /proc/1/cmdline

  nsh> sleep 100 &
  sleep [2:100]
