      drivers/serial/serial.c: Optimize wait time in tcdram() for buffer emptying · c6942f61
      Frank Benkert authored
      According to the specification, the close function must wait until all data
      has been written before it closes the file (except O_NONBLOCK is set). The
      maximum waiting time for this is not specified.
      
      To be able to edit the file list of the process, the close function has to lock
      the file list semaphore. After that the close function of the serial driver is
      called.
      
      Waiting for the complete transmission of all data is done in the serial driver.
      This causes the semaphore to remain locked until all data has been sent.
      However, no other thread of the process can edit the file list for that time
      (open, close, dup2, etc.). This is not optimal in a multithreaded environment.
      Therefore, we have to keep the waiting time within the driver as short as possible.

      Gregory Nutt authored
      This commit modifies the Unix domain local socket design.  Local sockets are built on top of pipes.  The Local socket implementation maintained file descriptors to interrupt with the pipes.  File descriptors have the bad property that they are valid only while running on the thread within the task that created the local socket.
      
      As a policy, all internal OS implementations must use "detached" files which are valid in any context and do not depend on the validity of a file descriptor at any point in time.  This commit converts the usage of file descriptors to detached files throughout the local socket implementation.
      
      Squashed commit of the following:
      
          net/local: Finish change to eliminate use of file descriptors.
          net/local:  A little more of the conversion.
          net/local: Beginning of chnages to eliminate use of file descriptors in the local socket implementeation. poll() will be a problem.

      Fix GPIO operation of STMPE811 driver.
      
      Fixed issues:
      1. STMPE811_GPIO_DIR was defined for register name
         and later was redefined to be the pin direction mask
         for `stmpe811_gpioconfig`
      
         I decided to change register name to be STMPE811_GPIO_DIR_REG,
         and keep pin direction mask STMPE811_GPIO_DIR, so that any
         external code that already use this driver will be unchanged.
      
      2. The STMPE811 register GPIO_DIR uses bit value 1 for output
         and 0 for input, but `stmpe811_gpioconfig` set the opposite.
      
      3. The call to `stmpe811_gpiowrite` from inside of `stmpe811_gpioconfig`
         leaded to deadlock.

          fs/userfs:  This completes coding of the UserFS client and of the UserFS feature in general.  This feature is being merged to main now because I believe it is innocuous.  It is, however, untesed.  The next step will be to develop a test case to verify the feature.
          fs/userfs:  Completes the request logic for the UserFS client.  Still need the logic that receives the responses.
          fs/userfs:  Completes coding for most of the server side of the user filesystem logic.
          fs/userfs:  Big design changes, simplications. Use Unix domain local sockets instead of message queues.  Easier to transfer big data in local sockets than message queues.  Remove character drvier 'factory' it is not necessary.
          fs/userfs:  Minor reparitioning; volume private info does not need to be held on the OS client side.
          libc/userfs:  Add some of the server side logic.
          fs/userfs:  Add some UserFS initialization logic.
          fs/userfs:  Add frame work for the UserFS proxy.  Remove all references to a block driver.  There is no block dricer... what was I thinking?
          fs/userfs: Add some initialization of the character driver, 'factory' device.
          fs/userfs:  Rename from fusefs to userfs to that we don't stomp on someone else's cool name.
          Add a header file describing the fusefs interface.

      Gregory Nutt authored
      Correct a problem that was causing an apparent directory to be reported as a file instead of a directory by opendir.
      
      This happened after adding these three new procfs entries:
      
        fs/block
        fs/mount
        fs/usage
      
      Of course, there is no directory fs in this case, only three files that have fs/ in their relative pathnames.  The logic was detecting that fs was the name of the enty to report, but it was then declaring that fs was a file (because fs/block is of type file).
      
      This was fixed by adding a check for matching lenghts.  i.e., if strlen(fs) != strlen(fs/block), then report fs as a directory instead of a file.

      Port STM32F7 I2C driver to STM32L4
      
      * arch/stm32l4: port STM32F7 I2C driver to STM32L4
      
          STM32L4 I2C driver is in work-in-progress state (plentiful of
          TODOs and #warnings) and lags many features found in more
          up-to-date STM32 I2C drivers. The peripheral on STM32F7 and
          STM32L4 are identical except for L4's 'wakeup from stop mode'
          flag and STM32F7's I2C driver is in more 'ready to use' state.
      
          Patch ports the STM32F7 I2C driver to STM32L4. The I2C clock
          configuration is kept the same as before (I2CCLK = PCLK1 80 Mhz)
          instead of switching to STM32F7 arch default that is I2CCLK=HSI.
          Further work would be to add configuration option for choosing
          I2C clock source instead of current hard-coded default.
