+ lower word.
+
+Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
+
+ * std-config.h (INLINE, STATIC_INLINE): Was being set to static
+ inline.. Only problem being that with ppc-opcode-simple this gave
+ it the chance to inline all the idecode functions with potentially
+ disasterous results on a 16mb PC. For moment hobble INLINE.
+
+ * configure.in, std-config.h (WITH_SMP): Make that 5 processors by
+ default ...
+
+ * configure.in: Tweek flags passed to gcc for --with-sim-warnings.
+ Firstly make them errors and secondly remove the options gcc-245
+ doesn't reconize.
+
+Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * misc.c (zalloc), cpu.c (cpu_init), devices
+ (console_io_read_buffer_callback, icu_io_read_buffer_callback,

+
+Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
+
+ * igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
+ generation of switch entries in tables - treat the same as
+ cracking/semantic functions.
+
+ * igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
+ of a boolean switch statement (field zero or non-zero).
+
+ * ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
+ switch/table generation ability of igen.
+
+ * igen.c (idecode_switch_leaf): Fix code output when a switch
+ statement needs to look up a table.
+
+ * igen.c (idecode_declare_if_switch): New function called from
+ gen_idecode_c - need to declare any idecode switch functions
+ before they are used in idecode tables.
+
+ * igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
+ idecode_crack_insn): Add is_inline_function argument to code
+ printing cracker functions which indicates if STATIC_IDECODE or
+ STATIC_INLINE_IDECODE should be used for definition. For
+ idecode_crack_insn (which implies not duplicating/expanding) don't
+ declare function as inline - we assume that the only time this is
+ code is generated is when things are being tested. For
+ idecode_crack_leaf, make static (instead of INLINE) if the
+ instructions parent is a table as function will always be called
+ via a table.
+
+ * igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
+ STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
+ called directly, all others are called via a table.
+
+ * igen.c (lf_print_semantic_function_header, semantics_h_leaf,
+ semantics_h_insn, semantics_h_function,
+ lf_print_c_semantic_function, semantics_c_function): Add
+ is_inline_function argument to lf_print_semantic_function_header
+ to indicate if an inline or static function declaration/definition
+ should be output. Depending on situtation call accordingly:
+ functions (not instruction semantic routines) are always inline;
+ Semantic routines are made inline when there is no icache (cache
+ will contain the function address) and are duplicating (see above)
+ and the parent of the instruction is a switch statement.
+
+ * igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
+ and moved to insn_table_find_opcode_field.
+
+ * table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
+
+ * igen.c (model_c_insn): Suggestion - document the name of the
+ instruction on each line of the instruction model table.

+Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
+
+ * std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
+ macro, indicates if the PowerPC's horrible XOR endian mode should

+ * vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
+ (vm_instruction_map_read): If XOR endian, xor the address
+ with a value from an xor table (indexed by size of access).
+
+ * vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
+ set up xor table to xor if there is a conflict between the
+ CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
+ check of suported change of endian mode from cpu.c to vm.c.
+
+ * vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
+ Hopefully added correct hack to handle XOR endian mode.
+
+ FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
+ little endian mode, the model accepts miss aligned transfers.
+
+ FIXME: Need to create an `init' device that, during
+ initializatioin for XOR mode, it mushes (XOR address) all the dma
+ data before passing it on to the core for storage. Just like the
+ real thing really.
+
+Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
+
+ * devices.c (halt_io_write_buffer_callback): Use value written to

+ * device_tree.h, device_tree.c (scand_*): New functions.
+
+Tue Nov 7 23:36:31 1995 Andrew Cagney <cagneyhighland.com.au>
+
+ * filter_filename.c, Makefile.in: Change so that only dependant on
+ a very limited nr of files. Stops an unnecessary dependency.
+
+Tue Nov 7 15:44:33 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * core.c (core_map_find_mapping): Use cpu_halt rather than error

+
+ * Makefile.in: Uncomment built file dependencies.
+
+ * configure.in: Rewrite --enable-sim switch handling to use the
+ autoconf builtins so it works correctly if the configure or

+ Makefile. Also document all of the --enable-sim switches
+ supported. Check whether getrusage and sys/resource.h are
+ supported.
+ * config.in: Regenerate.
+ * configure: Regenerate.
+ * Makefile.in: Add support for all of the variables set with
+ --enable-sim switches.

+
+ * configure.in: Add support for --enable-sim-opcode=stupid.

+
+ * igen.c (main), misc.h (target_a2i, i2target), misc.c: Add
+ functions to convert between target and igen internal bit numbers.
+ Make IO go through these functions. Add -b (bit size) and -h (high
+ bit nr) options to igen. Typical usage would be: ./igen -b 16 -h
+ 15 for a 16 bit instruction format with the msb given a number 15.
+
+Wed Nov 1 22:17:32 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * dgen.c (main): Was outputting optarg even when it was NULL.

+
+Tue Oct 31 21:31:32 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * ppc-opcode-stupid: Third example of use of opcode table - this
+ one expands all mtspr/mfspr and branch instructions. Appears to

+Wed Nov 1 10:49:48 1995 Michael Meissner <meissner@tiktok.cygnus.com>
+
+ * emul_netbsd.c (do_exit): Print arguments and close parenthesis

+ variables.
+ * configure: Regenerate from configure.in.
+ * Makefile.in: Add various Make variables that the various
+ switches alter.
+
+ * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC
+ and optimizing by default.
+
+Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
+ make them functions again. Appears 2.6.3 is confused by just a
+ macro.
+
+Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * ppc-endian.c (SWAP_8): Fix 8 byte swap!
+
+ * psim.c (psim_create): Not correctly checking that runtime
+ configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
+ matched the compiled in ones.
+
+ * debug.h (ITRACE), igen.c: Tidy up more tracing flags -
+ trace_semantics is now different to trace_idecode, the former
+ checks the cache.
+
+Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * ppc-instructions (mtsrin): Missing instruction
+ * ppc-instructions (mfsrin): Missing instruction

+
+ * std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
+ INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
+ Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
+ DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
+ the instruction or data critical paths.
+
+ * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
+ the inclusion of device_tree.c/emul_generic.c.
+
+Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

+
+ * cpu.h, cpu.c (cpu_init): New function, zero the registers before
+ the processor is started. Fixes problem of registers being
+ undefined when restarting from within gdb.
+
+ * cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
+ instruction cache (if present). Fixes problem of cpu caching gdb
+ breakpoint instructions.
+
+ FIXME: PSIM sometimes aborts calling error(), it should instead
+ call sim_error() say which takes care of housekeeping such as
+ saving the CIA before calling error.
+
+ * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
+ used when restarting a simulation because the latter has the
+ unwanted side effect (well I as a kernel hacker think it is) of
+ performing an isync when the instruction stream doesn't contain
+ one.
+
+Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance
+ monitoring module. Counts both instructions issued and
+ load/stores.
+
+ * NOTE: mon does not contain to count instruction loads as this
+ information is already available from the mon_issue() hook.
+
+ * igen.c (lf_print_c_semantic), vm_n.h: Add counting code.
+
+ * psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
+ a common monitor to each of the cpus. Delete
+ cpu_increment_number_of_insns() and cpu_get_number_of_insns()

+
+ * sim_calls.c, main.c, psim.c (psim_create): always create
+ `WITH_SMP' cpus. The actual number of CPU's active in a
+ simulation run is taken from the device node: /init/smp (an
+ integer). WITH_SMP changed to 2 (remember to put it back to 0).
+
+Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * system.c: More system call emulation. If code appears NetBSD
+ specific, make conditional to being compiled on a NetBSD system
+ (sigh).
+
+Wed Oct 18 23:02:20 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * Makefile.in, gen.c(delete), igen.c(new), dgen.c(new),
+ lf.[ch](new), table.[ch](new): Split into two generators - igen
+ that outputs the instruction tables and dgen that outputs the spr
+ tables. Add -f (filter out) flag to igen to filter out certain
+ instructions (ex 64 bit ones) from the created tables. Include
+ $(LIBIBERTY_LIB) in link options in case host lacks some libc
+ functions.
+
+ * NOTE: igen, since it was originally written for the
+ PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
+
+ * Makefile.in, std-config.h, ppc-cache-rules(new),
+ ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create
+ cache-rule and opcode-rule tables from macros found std-config.h.
+ Delete corresponding macro's from std-config.h.
+
+ * igen.c (gen_itable_c, gen_itable_h), Makefile.in: code to output
+ an table of all the instructions. Code to output a type
+ enumerating all the instructin names.
+
+ * igen.c(lf_print_c_semantic): Move call to increment instruction
+ counter so that it occures _after_ the instruction has been fully
+ validated, was double counting illegal/invalid instructions. Add
+ conditional so only compiled in when WITH_PROFILE enabled (enabled
+ by default).
+
+ * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
+ itable.h, count individual instruction types not just total,
+ adjust reporting functions to output this.
+
+ * ppc-instructions (64 bit Load Doubleword with Update Indexed):
+ Had 32./ instead of 31./
+
+ * ppc-instructions (64 bit Store Double Word Conditional Indexed):
+ bitrot - updated to use newer CR register operators.
+
+ * ppc-instructions (64bit Floating Convert from Integer
+ Doubleword): Correct call to Round_Float().
+
+Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * basics.h: #include "sim_callbacks.h" earlier so that its
+ prototypes are declared in all other header files.
+
+ * bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
+ doc in bits.h, remove dead code in bits.c, move ROTL32/ROTL64 into
+ bits.h.
+
+ * cpu.c(cpu_add_commas), device_tree.h, device_tree.c(scand_*):
+ Add size of buffer argument to functions writing a string into a
+ buffer. Check for buffer overflow.
+
+Sun Oct 15 22:16:11 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * devices.h, devices.c, debug.h, debug.c: add macro's for tracing

+ devices node when creating it.
+
+ * device_tree.c, debug.h, debug.c: Add tracing of `device-tree'.

+
+ * Makefile.in (clean): Delete *.i and *.out files.
+
+ * ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
+ macros for either assignment or return. Fix SWAP_8 to use a
+ union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
+ (ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
+ that hardwired swapping on/off, let optimizer delete dead code.
+
+ * main.c (main): Add printf that we caught a signal and print out

+ (gen_idecode_c): Move from here.
+
+Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * gen.c, ppc-instructions, psim.c: Fix code for generating
+ cracking instruction cache. Delete the code that cached just the
+ result from doing an instruction lookup - this ran slower than no
+ cache at all.
+
+Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
+
+ * Makefile.in (gen.o): Include $(INLINE_CFLAGS).

+ commas.
+ (cpu_print_info): Use it to print number_of_insns.
+
+ * ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
+ 2, 4, and 8 bytes.
+ (ENDIAN_N): If both target and host byte orders are known, don't
+ bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
+
+ * ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
+ to allow target specific H2T_n/T2H_n macros to be used.
+ (htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
+ non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
+ of the 3 instruction sequence that runs on 386s.
+
+ * std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
+ specified on the compile line.
+ (WITH_BSWAP): If not defined, define as 0.
+
+ * Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
+ default inline support. Pass INLINE_CFLAGS when compiling.
+
+ * devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
+ INLINE_DEVICES since GCC doesn't like inline functions that
+ accept variable arguments.
+ (stack_ioctl_callback): Make function just static because GCC
+ doesn't like inline functions that accept variable arguments.
+
+ * devices.h (STATIC_DEVICES): Define as empty if not defined.
+
+ * inline.c: Correct pathnames of included C files to match current
+ implementation.
+
+ * inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
+ non-zero, define STATIC_DEVICES to be static.

+
+Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * ppc-instructions: Initial cut of floating point suport added.
+ Of note include - use of host IEEE floating point instructions,
+ use of PowerPC manual pseudo code to handle the FPSCR. It is not
+ currently a pretty sight.
+
+ * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
+ merge into core.h, core.c, core_n.h. The type memory_map replaced
+ with core_map. This removes a level of pointer indirection when
+ translating an address.
+
+ * memory_map.h, memory_map.c, memory_map_n.h: delete.
+
+ * Makefile.in et.al (sorry): tweek to use new core, core_map and

+
+Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * devices.h, devices.c, memory_map.h, memory_map.c: Changed
+ callback interface so that there is a read/write buffer but no
+ read/write_word. VEA default memory read/write handler sometimes
+ couldn't resolve an access and of those some were for a memory
+ fault and some were because gdb was making a bogus request.
+
+ * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:
+ eliminate transfer_mode (raw or cooked) parameter from read/write
+ buffer.
+
+Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * ppc-instructions (fmul, fmuls): correct instruction format - had

+ handled by a device. Arguments passed across using a device ioctl
+ (hack).
+
+ * devices.h, devices.c: device ioctl callback changed to allow a
+ variable number of arguments. This gives greater flexability and
+ greater chance of bugs.
+
+Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>
+
+ * main.c (printf_filtered, error): Missing va_end() to close off

+ alternative file name to use in output files for things like #line
+ macros.
+
+ Makefile.in (tmp-gencode): Use gen -n so that debug info is
+ correct.
+
+ * Makefile.in (TARGETLIB): Use this instead of libsim.a in the
+ Makefile.

+
+PSIM is a program written in extended ANSI-C that implements an
+instruction level simulation of the PowerPC environment. It is freely
+available in source code form under the terms of the GNU General
+Public License (version 2 or later).
+
+The PowerPC Architecture is described as having three levels of
+compliance:
+
+ UEA - User Environment Architecture
+ VEA - Virtual Environment Architecture
+ OEA - Operating Environment Architecture
+
+PSIM both implements all three levels of the PowerPC and includes (for
+each level) a corresponding simulated run-time environment.
+
+In addition, PSIM, to the execution unit level, models the performance
+of most of the current PowerPC implementations (contributed by Michael
+Meissner). This detailed performance monitoring (unlike many other
+simulators) resulting in only a relatively marginal reduction in the
+simulators performance.
+

+
+
+ What features does PSIM include?
+
+ Monitoring and modeling
+
+ PSIM includes (thanks to Michael Meissner)
+ a detailed model of most of the PowerPC
+ implementations to the functional unit level.
+
+
+ SMP
+
+ The PowerPC ISA defines SMP synchronizing instructions.
+ This simulator implements a limited, but functional,
+ subset of the PowerPC synchronization instructions
+ behaviour. Programs that restrict their synchronization
+ primitives to those that work with this functional
+ sub-set (eg P() and V()) are able to run on the SMP
+ version of PSIM.
+
+ People intending to use this system should study
+ the code implementing the lwarx instruction.
+
+ ENDIAN SUPPORT
+
+ PSIM implements the PowerPC's big and little (xor
+ endian) modes and correctly simulates code that
+ switches between these two modes.
+
+ In addition, psim can model a true little-endian
+ machine.
+
+ ISA (Instruction Set Architecture) models
+
+ PSIM includes a model of the UEA, VEA and OEA. This
+ includes the time base registers (VEA) and HTAB
+ and BATS (OEA).
+
+ In addition, a preliminary model of the 64 bit
+ PowerPC architecture is implemented.
+
+ IO Hardware
+
+ PSIM's internals are based around the concept
+ of a Device Tree. This tree intentionally
+ resembles that of the Device Tree found in
+ OpenBoot firmware. PSIM is flexible enough
+ to allow the user to fully configure this device
+ tree (and consequently the hardware model) at
+ run time.
+
+ Run-time environments:
+
+ PSIM's UEA model includes emulation for BSD
+ based UNIX system calls.
+
+ PSIM's OEA model includes emulation of either:
+
+ o OpenBoot client interface
+
+ o MOTO's BUG interface.
+
+
+ Floating point
+
+ Preliminary support for floating point is included.
+
+
+ Who would be interested in PSIM?
+
+ o the curious
+
+ Using psim, gdb, gcc and binutils the curious
+ user can construct an environment that allows
+ them to play with PowerPC Environment without
+ the need for real hardware.
+
+
+ o the analyst
+
+ PSIM includes many (contributed) monitoring
+ features which (unlike many other simulators)
+ do not come with a great penalty in performance.
+
+ Thus the performance analyst is able to use
+ this simulator to analyse the performance of
+ the system under test.
+
+ If PSIM doesn't monitor a components of interest,
+ the source code is freely available, and hence
+ there is no hinderance to changing things
+ to meet a specific analysts needs.
+
+
+ o the serious SW developer
+
+ PSIM models all three levels of the PowerPC
+ Architecture: UEA, VEA and OEA. Further,
+ the internal design is such that PSIM can
+ be extended to support additional requirements.
+
+
+ What performance analysis measurements can PSIM perform?
+
+ Below is the output from a recent analysis run
+ (contributed by Michael Meissner):
+
+ For the following program:
+
+ long
+ simple_rand ()
+ {
+ static unsigned long seed = 47114711;
+ unsigned long this = seed * 1103515245 + 12345;
+ seed = this;
+ /* cut-cut-cut - see the file RUN.psim */
+ }
+
+ Here is the current output generated with the -I switch on a P90
+ (the compiler used is the development version of GCC with a new
+ scheduler replacing the old one):
+
+ CPU #1 executed 41,994 AND instructions.
+ CPU #1 executed 519,785 AND Immediate instructions.
+ .
+ .
+ .
+ CPU #1 executed 1 System Call instruction.
+ CPU #1 executed 207,746 XOR instructions.
+
+ CPU #1 executed 23,740,856 cycles.
+ CPU #1 executed 10,242,780 stalls waiting for data.
+ CPU #1 executed 1 stall waiting for a function unit.
+ .
+ .
+ .
+ CPU #1 executed 3,136,229 branch functional unit instructions.
+ CPU #1 executed 16,949,396 instructions that were accounted for in timing info.
+ CPU #1 executed 871,920 data reads.
+ CPU #1 executed 971,926 data writes.
+ CPU #1 executed 221 icache misses.
+ CPU #1 executed 16,949,396 instructions in total.
+
+ Simulator speed was 250,731 instructions/second
+
+
+ What motivated PSIM?
+
+ As an idea, psim was first discussed seriously during mid
+ 1994. At that time its main objectives were:
+
+
+ o good performance
+
+ Many simulators loose out by only providing
+ a binary interface to the internals. This
+ interface eventually becomes a bottle neck
+ in the simulators performance.
+
+ It was intended that PSIM would avoid this
+ problem by giving the user access to the
+ full source code.
+
+ Further, by exploiting the power of modern
+ compilers it was hoped that PSIM would achieve
+ good performance with out having to compromise
+ its internal design.
+
+
+ o practical portability
+
+ Rather than try to be portable to every
+ C compiler on every platform, it was decided
+ that PSIM would restrict its self to supporting
+ ANSI compilers that included the extension
+ of a long long type.
+
+ GCC is one such compiler, consequently PSIM
+ should be portable to any machine running GCC.
+
+
+ o flexibility in its design
+
+ PSIM should allow the user to select the
+ features required and customise the build
+ accordingly. By having the source code,
+ the compiler is able to eliminate any un
+ used features of the simulator.
+
+ After all, let the compiler do the work.
+
+
+ o SMP
+
+ A model that allowed the simulation of
+ SMP platforms with out the large overhead
+ often encountered with such models.
+
+
+ PSIM achieves each of these objectives.
+
+
+ Is PSIM PowerPC Platform (PPCP) (nee CHRP) Compliant?
+
+ No.
+
+ Among other things it does not have an Apple ROM socket.
+
+
+ Could PSIM be extended so that it models a CHRP machine?
+
+ Yes.
+
+ PSIM has been designed with the CHRP spec in mind. To model
+ a CHRP desktop the following would need to be added:
+
+ o An apple ROM socket :-)
+
+ o Model of each of the desktop IO devices
+
+ o An OpenPIC device.
+
+ o RTAS (Run Time Abstraction Services).
+
+ o A fully populated device tree.
+
+
+ Is the source code available?
+
+ Yes.
+
+ The source code to PSIM is available under the terms of
+ the GNU Public Licence. This allows you to distribute
+ the source code for free but with certain conditions.
+
+ See the file:
+
+ ftp://archie.au/gnu/COPYING
+
+ For details of the terms and conditions.
+
+
+ Where do I send bugs or report problems?
+
+ There is a mailing list (subscribe through majordomo@ci.com.au) at:
+
+ powerpc-psim@ci.com.au
+
+ If I get the ftp archive updated I post a note to that mailing list.
+ In addition your welcome to send bugs or problems either to me or to
+ that e-mail list.
+
+ This list currently averages zero articles a day.
+
+
+ Does PSIM have any limitations or problems?
+
+ PSIM can't run rs6000/AIX binaries - At present PSIM can only
+ simulate static executables. Since an AIX executable is
+ never static, PSIM is unable to simulate its execution.
+
+ PSIM is still under development - consequently there are going
+ to be bugs.
+
+ See the file BUGS (included in the distribution) for any
+ other outstanding issues.
