    2525// The printk.c and printk.h files define the functions used by the kernel
    26 // to display messages on the kernel text terminal, using a busy waiting
    27 // policy if required : these functions does not use the TXT kernel thread,
    28 // and does not deschedule if TXT peripheral is not available.
    29 // These functions use the generic TXT device to call the proper implementation
     26// to display messages on a text terminal.
     27// Two access modes are supported:
     28// - The printk() function displays kernel messages on the kernel terminal TXT0,
     29//   using a busy waiting policy: It calls directly the relevant TXT driver,
     30//   after taking the TXT0 chdev lock for exclusive access to the TXT0 terminal.
     31// - The user_printk() function displays messages on the calling thread private
     32//   terminal, using a descheduling policy: it register the request in the selected
     33//   TXT chdev waiting queue and deschedule. The calling thread is reactivated by
     34//   the IRQ signaling completion.
     35// Both functions use the generic TXT device to call the proper implementation
    3036// dependant TXT driver.
     37// Finally these files define a set of conditionnal trace <***_dmsg> for debug.
