* or1k: Make heap start configurableJeff Johnston2015-05-272-2/+7
| | | | | | | | | - Previously the heap started right after the bss section. This can now be configured by changing the _or1k_heap_start symbol that defaults to the old value (&end). In board_init_early, we can now set this to another value. * or1k/sbrk.c: Allow for different heap start
* or1k: UART also accept timeout interruptJeff Johnston2015-05-272-3/+9
| | | | | | | - The UART interrupt only handled receiver FIFO full interrupts, but we also want to handle timeout interrupts. * or1k/or1k_uart.c: Fix interrupts
* Bug fix in timer for or1kJeff Johnston2015-05-272-1/+5
| | | | | | - Properly set the interrupt pending flag in the timer mode register. * or1k/timer.c: Properly set interrupt flags
* Store entire context for or1kJeff Johnston2015-05-272-0/+14
| | | | | | | | - Store the exception program counter (from EPCR) and exception status register (from ESR) also during the exception. A runtime system may replace them thereby to implement a thread switch. * or1k/exception-asm.S: Store missing state
* Fix exception stack frame for or1kJeff Johnston2015-05-273-3/+8
| | | | | | | | | - We do not need a red zone here, as we do not operate on the current stack, but always use the clear exception stack. Also reserve two extra words for the context to store EPCR and ESR. * or1k/crt0.S: Fix exception stack frame * or1k/exception-asm.S: ditto
* Fix interrupt handling for or1k.Jeff Johnston2015-05-272-28/+28
| | | | | | | | | | | | - During interrupt handling the PICSR, table pointers and current interrupt line have been saved in incorrect registers and/or stored on the stack. - Save the pointer in r16/r18, PICSR in r20 and the current interrupt line in r22. Those are callee-saved registers, so that the register values will be preserved. * or1k/interruts-asm.S: Change registers to callee-saved.
* Add a check that the data area does not overrun the stack.Nick Clifton2015-05-277-3/+110

* Fix OPOST for non-Cygwin pty slavesTakashi Yano2015-04-235-19/+178
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * fhandler.h (class fhandler_base): Add virtual function get_io_handle_cyg() to get handle from which OPOST-processed output is read on PTY master. (class fhandler_pty_slave): Add variable output_handle_cyg to store a handle to which OPOST-processed output is written. Add two functions, i.e., set_output_handle_cyg() and get_output_handle_cyg(), regarding variable output_handle_cyg. Now, output_handle is used only by native windows program. The data before OPOST-processing is written to output_handle and OPOST-processing is applied in the master-side. For a cygwin process, OPOST-processing is applied in the slave-side, and the data after OPOST-processing is written to output_handle_cyg. (class fhandler_pty_master): Add two variables, i.e., io_handle_cyg and to_master_cyg, to store handles of a pipe through which OPOST-processed output passes. Add pty_master_fwd_thread and function pty_master_fwd_thread() for a thread which applies OPOST-processing and forwards data from io_handle to to_master_cyg. Add function get_io_handle_cyg() regarding variable io_handle_cyg. Now, the pipe between io_handle and to_master are used only by native windows program for applying OPOST-processing in the master-side. For a cygwin process, the pipe between io_handle_cyg and to_master_cyg is used for passing through the data which is applied OPOST-processing in the slave-side. * fhandler_tty.cc (struct pipe_reply): Add member to_master_cyg. (fhandler_pty_master::process_slave_output): Read slave output from io_handle_cyg rather than io_handle. (fhandler_pty_slave::fhandler_pty_salve): Initialize output_handle_cyg. (fhandler_pty_slave::open): Set output_handle_cyg by duplicating handle to_master_cyg on PTY master. (fhandler_pty_slave::close): Close handle output_handle_cyg. (fhandler_pty_slave::write): Write data to output_handle_cyg rather than output_handle. (fhandler_pty_slave::fch_close_handles): Close handle output_handle_cyg.

(fhandler_pty_master::close): Print to_master_cyg as well in debug message. Terminate master forwarding thread. Close handles to_master_cyg and io_handle_cyg. (fhandler_pty_master::ioctl): Use io_handle_cyg rather than to_master. (fhandler_pty_master::pty_master_thread): Add code for duplicating handle to_master_cyg. (fhandler_pty_master::pty_master_fwd_thread): New function for a thread to forward OPOST-processed data from io_handle to to_master_cyg. This thread applies OPOST-processing to the output of native windows program. (::pty_master_fwd_thread): Ditto. (fhandler_pty_master::setup): Create a new pipe to pass thruegh OPOST- processed output. Create new thread to forward data from io_handle to to_master_cyg. Set handle to_master_cyg to tty. Print io_handle_cyg as well in debug message. Close handles io_handle_cyg and to_master_cyg in case of error. (fhandler_pty_master::fixup_after_fork): Set handle to_master_cyg to tty. Copy handle to_master_cyg from arch->to_master_cyg. (fhandler_pty_master::fixup_after_exec): Clean up to_master_cyg. * select.cc: Check handle returned by get_io_handle_cyg() rather than get_handle(). * tty.h (class tty): Add variable _to_master_cyg to store a handle to which OPOST-processed data is written.
