HwbpManual test was broken:

  • Value read back from tselect was compared with tdata1 value.
    value = self.gdb.p("$tselect")
    if value == tdata1:
    break
    This resulted in the test being reported as not supported, after all the triggers were checked.
  • tdata1.type field was not set to mcontrol.
  • tselect value used to be changed by handle_reset and not restored.
    1:
    addi t0, t0, 1
    csrw CSR_TSELECT, t0
    csrw CSR_TDATA1, zero
    csrr t1, CSR_TSELECT
    beq t0, t1, 1b
  • Manual breakpoint used to be left behind.
