-From: Jiri Gaisler <jiri@gaisler.se>
-Date: Wed, 23 Dec 2015 16:17:10 -0500
-Subject: [PATCH 1/9] sim/erc32: Use gdb callback for UART I/O when linked with
- gdb.
-
- * erc32.c (<errno.h>): new include.
- (init_stdio, restore_stdio): don't set tty attributes if ttys not open.
- (DO_STDIO_READ, port_init, read_uart, write_uart, flush_uart, uarta_tx,
- uartb_tx, uart_rx): Use gdb callbacks for console I/O, fix whitespace.
-
- * func.c (dumbio, tty_setup): new variables.
- (nouartrx): new variable, set to 1 if UART receiver should be disabled.
- (sim_callback): new variable, pointer to gdb host callback structure.
-
- * interf.c (dumbio): remove duplicate extern declaration.
- (sim_callback): moved to func.c.
- (sim_open): add -nouartrx switch to disable UART input.
-
- * sis.c (main): Add -nouartrx switch to disable UART input.
-
- * sis.h (nouartrx, sim_callback, dumbio, tty_setup): add external declare.

-From c14cfd7c752600f375806e89dcf578d38fb4d27d Mon Sep 17 00:00:00 2001
-From: Jiri Gaisler <jiri@gaisler.se>
-Date: Wed, 23 Dec 2015 16:21:52 -0500
-Subject: [PATCH 2/9] sim/erc32: Access memory subsystem through struct memsys.
-
- Introduce an common API to access emulated memory. This allows
- to emulate different types of SPARC-based CPUs.
-
- * erc32.c (reset, error_mode, sim_halt, close_port, exit_sim, init_stdio,
- restore_stdio, memory_iread, memory_read, memory_write, sis_memory_write,
- sis_memory_read): Mark static.
- (sim_stop): Move to interf.c.
- (erc32sys): New variable, exporting memory operations through struct memsys.
- * exec.c (dispatch_instruction): Access memory through common API.
- * func.c (ms): New global, pointing to active memory sub-system.
- (exec_cmd, print_insn_sparc_sis, dis_mem, reset_all, bfd_load): Access memory
- through common API.
- * interf.c (sregs, ctrl_c, sis_verbose): move extern declaration to sis.h.
- (run_sim, sim_close, sim_write, sim_read, flush_windows): Access memory through
- common API.
- (sim_stop): Add.
- * sis.c (sregs, ctrl_c, sis_verbose): move extern declaration to sis.h.
- (run_sim, main): Access memory through common API.
- * sis.h (memsys): Define struct memsys as common memory API. Remove declaration
- of functions marked as static.

-Subject: [PATCH 4/9] Add support for LEON3 processor emulation.
-
- Added memory and I/O sub-system to emulate a LEON3 processor.
- The cache and MMU are not emulated but enough functionallity
- is provided to run any RTEMS and BCC compiled application.
- The code is based on erc32.c and modified to emulate the
- LEON3 address space and peripheral operations.
-
- * Makefile.in: Added new object files
- * README.leon3: New file, documentation for leon3 emulation
- * README.sis: Updated documentation for simulator commands
- * grlib.c: New file, emulates leon3/grlib peripheral devices
- * grlib.h: New file, definition of grlib plug&play values
- * leon3.c: New file, emulation of leon3 memory and interrupt controller
- * erc32.c (memory_read, memory_write): Remove asi from parameters,
- compute locally.
- (memory_read_asi, memory_write_asi): New memory function with asi
- parameter.
- (get_mem_ptr): Allow reading of I/O registers if access has exactly
- 4 byte size.
- (boot_init): Mark as static. Add new struct members.
- * exec.c (dispatch_instruction): Emulate leon3 V8 mul/div and asr17.
- Emulate LDA/LDDA/LDUBA/LDUHA/LDSTA/SWAPA/STA/STBA/SHA/STDA instructions
- separately.
- (fpexec): Use integer operations for FMOV to avoid FPU traps on x86.
- (execute_trap): Support single vector trapping for leon3
- (init_regs): Add leon3 vendor/device ID to %psr.
- * func.c (sis_version): Set version to 2.8 to indicate support of leon3.
- (exec_cmd): Call boot_init through memsys structure. Set PC to start
- address of last loaded binary, and initialize registers if not 0.
- (show_stat): Use 64-bit floats when calculating simulator statistics.
- * interf.c (run_sim): Call boot_init through memsys struct. Add -leon3
- option.
- (sim_open): Set leon3 default frequency to 50 MHz. Print out current
- emulation mode (erc32/leon3).
- (flush_windows): Skip asi when flushing windows.
- * sis.c (main): Update maintainer email. Add -leon3 switch. Set default
- leon3 frequency to 50 MHz. Print out current emulation mode.
- * sis.h: Add memsys struct for leon3.

-+1. LEON3 emulation
-+
-+The file 'leon3.c' contains a model of simple LEON3 sub-system. It
-+contains 16 Mbyte ROM and 16 Mbyte RAM. Standard peripherals
-+such as interrupt controller, UART and timer are provided.
-+The model can execute leon3 binaries that do not require an
-+MMU.
-+
-+To start sis in Leon3 mode, add the -leon3 switch. In gdb,
-+use 'target sim -leon3' .
-+
-+1.1 UART
-+
-+The UART emulates an APBUART and is located at address 0x80000100.
-+The following registers are implemented:
-+
-+- UART RX and TX register (0x80000100)
-+- UART status register (0x80000104)
-+
-+The UART generates interrupt 3.
-+
-+1.2 Timer unit (GPTIMER)
-+
-+The GPTIMER programmable counter is emulated and located at
-+address 0x80000300. It is configured with two timers and separate
-+interrupts (8 and 9).
-+
-+1.3 Interrupt controller
-+
-+The IRQMP interrupt controller is implemented as described in the
-+GRLIB IP manual, with the exception of the interrupt level register.
-+Extended interrupts are not supported. The registers are located
-+at address 0x80000200.
-+
-+1.5 Memory interface
-+
-+The following memory areas are valid for the Leon3 simulator:
-+
-+0x00000000 - 0x01000000 ROM (16 Mbyte, loaded at start-up)
-+0x40000000 - 0x41000000 RAM (16 Mbyte, loaded at start-up)
-+0x80000000 - 0x81000000 APB bus, including plug&play
-+0xFFFFF000 - 0xFFFFFFFF AHB plug&play area
-+

-From: Jiri Gaisler <jiri@gaisler.se>
-Date: Tue, 29 Dec 2015 20:57:59 -0500
-Subject: [PATCH 5/9] sim/erc32: Add support for LEON2 processor emulation.
-
- Added memory and I/O sub-system to emulate a LEON2 processor.
- The cache and MMU are not emulated but enough functionallity
- is provided to run any RTEMS and BCC compiled application.
- The code is based on erc32.c and modified to emulate the
- LEON2 address space and peripheral operations.
-
- * Makefile.in : Added new object files.
- * exec.c (init_regs): Add leon2 vendor/device ID to %psr.
- * interf.c (sim_open): Add -leon2 to start-up switches.
- (sim_open): Set leon2 default frequency to 50 MHz. Print out current
- emulation mode.
- * leon2.c : New file, emulation of leon2 memory and peripherals.
- * sis.c (main): Add -leon2 switch. Set default leon2 frequency to 50 MHz.
- * sis.h: Add memsys struct for leon2.

--How to use SIS with GDB
-------------------------
--
--1. Building GDB with SIS
--
--To build GDB with the SIS/ERC32 simulator, configure with option
--'--target sparc-erc32-aout' and build as usual.
--
--2. Attaching the simulator
--
--To attach GDB to the simulator, use:
--
--target sim [options] [files]
--
--The following options are supported:
--
-- -nfp Disable FPU. FPops will cause an FPU disabled trap.
--
-- -freq <f> Set the simulated "system clock" to <f> MHz.
--
-- -v Verbose mode.
--
-- -nogdb Disable GDB breakpoint handling (see below)
--
--The listed [files] are expected to be in aout format and will be
--loaded in the simulator memory prior. This could be used to load
--a boot block at address 0x0 if the application is linked to run
--from RAM (0x2000000).
--
--To start debugging a program type 'load <program>' and debug as
--usual.
--
--The native simulator commands can be reached using the GDB 'sim'
--command:
--
--sim <sis_command>
--
--Direct simulator commands during a GDB session must be issued
--with care not to disturb GDB's operation ...
--
--For info on supported ERC32 functionality, see README.sis.
--
--
--3. Loading aout files
--
--The GDB load command loads an aout file into the simulator
--memory with the data section starting directly after the text
--section regardless of wich start address was specified for the data
--at link time! This means that your applications either has to include
--a routine that initialise the data segment at the proper address or
--link with the data placed directly after the text section.
--
--A copying routine is fairly simple, just copy all data between
--_etext and _data to a memory loaction starting at _environ. This
--should be done at the same time as the bss is cleared (in srt0.s).
--
--
--4. GDB breakpoint handling
--
--GDB inserts breakpoint in the form of the 'ta 1' instruction. The
--GDB-integrated simulator will therefore recognize the breakpoint
--instruction and return control to GDB. If the application uses
--'ta 1', the breakpoint detection can be disabled with the -nogdb
--switch. In this case however, GDB breakpoints will not work.

-+1. LEON2 emulation
-+
-+The file 'leon2.c' contains a model of simple LEON2 sub-system. It
-+contains 16 Mbyte ROM and 16 Mbyte RAM. Standard peripherals
-+such as interrupt controller, UART and timer are provided.
-+The model can execute leon2 binaries that do not require an
-+MMU.
-+
-+To start sis in Leon2 mode, add the -leon2 switch. In gdb,
-+use 'target sim -leon2' .
-+
-+1.1 UART
-+
-+One LEON2 UART is emaulted, and is located at address 0x80000070.
-+The following registers are implemeted:
-+
-+- UART RX and TX register (0x80000070)
-+- UART status register (0x80000074)
-+
-+The UART generates interrupt 3.
-+
-+1.2 Timer unit
-+
-+The LEON2 timer unit is emulated and located at address 0x80000040.
-+It is configured with two timers and separate interrupts (8 and 9).
-+The scaler is configured to 16 bits, while the counters are 32 bits.
-+
-+1.3 Interrupt controller
-+
-+The interrupt controller is implemented as described in the
-+LEON2 IP manual, with the exception of the interrupt level register.
-+Secondary interrupts are not supported. The registers are located
-+at address 0x80000090.
-+
-+1.5 Memory interface
-+
-+The following memory areas are valid for the Leon3 simulator:
-+
-+0x00000000 - 0x01000000 ROM (16 Mbyte, loaded at start-up)
-+0x40000000 - 0x41000000 RAM (16 Mbyte, loaded at start-up)
-+0x80000000 - 0x81000000 APB bus, including plug&play
-+0xFFFFF000 - 0xFFFFFFFF AHB plug&play area
-+
-+Access to non-existing memory will result in a memory exception trap.
-+
-+1.8 Power-down mode
-+
-+The Leon2 power-down register (0x80000018) is supported. When power-down is
-+entered, time is skipped forward until the next event in the event queue.
-+However, if the simulator event queue is empty, power-down mode is not
-+entered since no interrupt would be generated to exit from the mode. A
-+Ctrl-C in the simulator window will exit the power-down mode.

-
--The core interacts with the user-defined memory modules through
--a number of functions. The memory module must provide the following
--functions:
--
--int memory_read(asi,addr,data,ws)
--int asi;
--unsigned int addr;
--unsigned int *data;
--int *ws;
--
--int memory_write(asi,addr,data,sz,ws)
--int asi;
--unsigned int addr;
--unsigned int *data;
--int sz;
--int *ws;
--
--int sis_memory_read(addr, data, length)
--unsigned int addr;
--char *data;
--unsigned int length;
--
--int sis_memory_write(addr, data, length)
--unsigned int addr;
--char *data;
--unsigned int length;
--
--int init_sim()
--
--int reset()
--
--int error_mode(pc)
--unsigned int pc;
--
--memory_read() is used by the simulator to fetch instructions and
--operands. The address space identifier (asi) and address is passed as
--parameters. The read data should be assigned to the data pointer
--(*data) and the number of waitstate to *ws. 'memory_read' should return
--0 on success and 1 on failure. A failure will cause a data or
--instruction fetch trap. memory_read() always reads one 32-bit word.
--
--sis_memory_read() is used by the simulator to display and disassemble
--memory contants. The function should copy 'length' bytes of the simulated
--memory starting at 'addr' to '*data'.
--The sis_memory_read() should return 1 on success and 0 on failure.
--Failure should only be indicated if access to unimplemented memory is attempted.
--
--memory_write() is used to write to memory. In addition to the asi
--and address parameters, the size of the written data is given by 'sz'.
--The pointer *data points to the data to be written. The 'sz' is coded
--as follows:
--
-- sz access type
-- 0 byte
-- 1 halfword
-- 2 word
-- 3 double-word
--
--If a double word is written, the most significant word is in data[0] and
--the least significant in data[1].
--
--sis_memory_write() is used by the simulator during loading of programs.
--The function should copy 'length' bytes from *data to the simulated
--memory starting at 'addr'. sis_memory_write() should return 1 on
--success and 0 on failure. Failure should only be indicated if access
--to unimplemented memory is attempted. See erc32.c for more details
--on how to define the memory emulation functions.
--
--The 'init_sim' is called once when the simulator is started. This function
--should be used to perform initialisations of user defined memory or
--peripherals that only have to be done once, such as opening files etc.
--
--The 'reset' is called every time the simulator is reset, i.e. when a
--'run' command is given. This function should be used to simulate a power
--on reset of memory and peripherals.
--
--error_mode() is called by the simulator when the IU goes into error mode,
--typically if a trap is caused when traps are disabled. The memory module
--can then take actions, such as issue a reset.
--
--sys_reset() can be called by the memory module to reset the simulator. A
--reset will empty the event queue and perform a power-on reset.
--
--4. Events and interrupts
--
--The simulator supports an event queue and the generation of processor
--interrupts. The following functions are available to the user-defined
--memory module:
--
--event(cfunc,arg,delta)
--void (*cfunc)();
--int arg;
--unsigned int delta;
--
--set_int(level,callback,arg)
--int level;
--void (*callback)();
--int arg;
--
--clear_int(level)
--int level;
--
--sim_stop()
--
--The 'event' functions will schedule the execution of the function 'cfunc'
--at time 'now + delta' clock cycles. The parameter 'arg' is passed as a
--parameter to 'cfunc'.
--
--The 'set_int' function set the processor interrupt 'level'. When the interrupt
--is taken, the function 'callback' is called with the argument 'arg'. This
--will also clear the interrupt. An interrupt can be cleared before it is
--taken by calling 'clear_int' with the appropriate interrupt level.
--
--The sim_stop function is called each time the simulator stops execution.
--It can be used to flush buffered devices to get a clean state during
--single stepping etc.
--
--See 'erc32.c' for examples on how to use events and interrupts.

-Subject: [PATCH 8/9] Add watchpoint support to gdb simulator interface.
-
- Currently, only the sparc sim supports watchpoints. Stubs for the
- watchpoint functions were added to all other built-in sims
- to avoid linking errors.
