      chore(epicardium): Use panic() for all critical errors · 0e5c6243
      Rahix authored
      
      
      Unify unrecoverable errors to use panic() in all cases.  This will allow
      further changes to panic() to work for all critical errors.

      chore(epicardium): Switch from MXC_ASSERT to assert · 070867f8
      Rahix authored
      
      
      Newlib assert uses __assert_func and thus our panic() function while
      MXC_ASSERT uses a custom assertion logic.  Newlib assert is also more
      portable as it works in expression position while MXC_ASSERT only works
      as a statement.

      feat(epicardium): Use panic() for assertion failures · 9d44017b
      Rahix authored
      
      
      Define `__assert_func()` so a failing `assert()` will trigger a panic.

      feat(epicardium): Add a panic() function · 1536da34
      Rahix authored
      In unrecoverable situations we should provide a common way to output the
      cause of the error and then reset the CPU.  The panic() function is
      mean to be exactly that.  It outputs the error-cause, stack-trace, and
      firmware revision, accompanied by a link to the issue-tracker to
      encourage people to report the error.  After a timeout of ~1.5s it
      resets the CPU and reboots.
      
      Future Work:
      
       - Right now, the stack-trace only has a depth of one which is the
         return address from where panic() was called.  In the future it might
         make sense to provide a deeper stack-trace if a robust implementation
         is possible.
       - Integration of @msgctl
      
      's faultscreen (!79) so users who don't have
         the serial console open at all times can also see what happened.

      feat(serial): Add function to switch serial to synchronous · 5e25bc89
      Rahix authored
      
      
      In severe error conditions, asynchronous prints will never work.  For
      such cases we need a way to make prints happen synchronously again, the
      same way it works during early boot.  Add a serial_return_to_synchronous()
      function which unconditionally switches the serial driver code to
      synchronous mode.
      
      Only use this function in unrecoverable error conditions!

      fix(libcard10): Mark card10_reset() as noreturn · 8ac93244
      Rahix authored
      
      
      card10_reset() won't ever return to where it was called from.  Telling
      the compiler this can help with program-flow analysis.

      fix(gfx/display): Draw partially clipped primitives · 14d5abcc
      Philip Stewart authored and Rahix's avatar Rahix committed
      Fix two bugs in the display/gfx module:
      
      1. The animation of the simple_menu used in the main menu had the issue
         that there is a black line visible at the top.  This is due the
         gfx_puts method ignoring lines, where the top pixel of the string is
         above the top of the screen.  As gfx_puts uses gfx_setpixel which in
         turn ignores pixels outside of the screen, remove the check in
         gfx_puts.
      2. X and Y coordinates were cast to unsigned-ints before being given to
         the gfx-library which means calls like circ(0, -10, 30) would be draw
         at coordinates like [0,65526].  Fix this by changing the data-type of
         all coordinates to signed-integers.
      
      Also remove the x and y ranges from the documentation of the individual
      python functions and instead add a general documentation about the
      screen and it's size/coordinate system.
