20050408	Some minor updates to the wdc. Linux now doesn't complain
		anymore if a disk is non-present.
20050409	Various minor fixes (a bintrans bug, and some other things).
		The wdc seems to work with Playstation2 emulation, but there
		is a _long_ annoying delay when disks are detected.
		Fixing a really important bintrans bug (when devices and RAM
		are mixed within 4KB pages), which was triggered with
		NetBSD/playstation2 kernels.
20050410	Adding a dummy dev_ps2_ether (just so that NetBSD doesn't
		complain as much during bootup).
		Symbols starting with '$' are now ignored.
		Renaming dev_ps2_ohci.c to dev_ohci.c, etc.
20050411	Moving the bintrans-cache-isolation check from cpu_mips.c to
		cpu_mips_coproc.c. (I thought this would give a speedup, but
		it's not noticable.)
		Better playstation2 sbus interrupt code.
		Skip ahead many ticks if the count register is read manually.
		(This increases the speed of delay-loops that simply read
		the count register.)
20050412	Updates to the playstation2 timer/interrupt code.
		Some other minor updates.
20050413	NetBSD/cobalt runs from a disk image :-) including userland;
		updating the documentation on how to install NetBSD/cobalt
		using NetBSD/pmax (!).
		Some minor bintrans updates (no real speed improvement) and
		other minor updates (playstation2 now uses the -o options).
20050414	Adding a dummy x86 (and AMD64) mode.
20050415	Adding some (32-bit and 16-bit) x86 instructions.
		Adding some initial support for non-SCSI, non-IDE floppy
		images. (The x86 mode can boot from these, more or less.)
		Moving the devices/ and include/ directories to src/devices/
		and src/include/, respectively.
20050416	Continuing on the x86 stuff. (Adding pc_bios.c and some simple
		support for software interrupts in 16-bit mode.)
20050417	Ripping out most of the x86 instruction decoding stuff, trying
		to rewrite it in a cleaner way.
		Disabling some of the least working CPU families in the
		configure script (sparc, x86, alpha, hppa), so that they are
		not enabled by default.
20050418	Trying to fix the bug which caused problems when turning on
		and off bintrans interactively, by flushing the bintrans cache
		whenever bintrans is manually (re)enabled.
20050419	Adding the 'lswi' ppc instruction.
		Minor updates to the x86 instruction decoding.
20050420	Renaming x86 register name indices from R_xx to X86_R_xx (this
		makes building on Tru64 nicer).
20050422	Adding a check for duplicate MIPS TLB entries on tlbwr/tlbwi.
20050427	Adding screenshots to guestoses.html.
		Some minor fixes and testing for the next release.

64 <h3>Hello world:</h3>
65
66 You might want to use the emulator to develop programs on your own,
67 not just run precompiled kernels such as NetBSD. To get started, I recommend
68 that you do two things:
69
70 <p>
71 <ul>
72 <li>Build and install a cross-compiler for MIPS.
73 <li>Compile this hello world program, and run it in the emulator.
74 </ul>
75
76 <p>
77 The emulator has several modes where it doesn't emulate any real machine.
78 It can either run in "bare" mode, where no devices are included by default
79 (just the CPU), or in a "test" mode where some simple devices are
80 emulated.

116 This hello world program is available here as well:
117 <a href="hello_mips.c">hello_mips.c</a>
118 <p>
119 I recommend that you build a GCC cross compiler for the
120 <b>mips64-unknown-elf</b> target, and install it. Other compilers could
121 work too, but GCC is good because of its portability. Then try to compile
122 the hello world program:
123 <pre>
124 $ <b>mips64-unknown-elf-gcc -O2 hello_mips.c -mips4 -mabi=64 -c</b>
125 $ <b>mips64-unknown-elf-ld -Ttext 0xa800000000030000 -e f hello_mips.o -o hello_mips --oformat=elf64-bigmips</b>
126 $ <b>file hello_mips</b>
127 hello_mips: ELF 64-bit MSB mips-4 executable, MIPS R3000_BE, version 1 (SYSV), statically linked, not stripped
128 $ <b>gxemul -q -E testmips hello_mips</b>
129 Hello world
130
131 $ <b>mips64-unknown-elf-gcc -O2 hello_mips.c -c</b>
132 $ <b>mips64-unknown-elf-ld -Ttext 0x80030000 -e f hello_mips.o -o hello_mips</b>
133 $ <b>file hello_mips</b>
134 hello_mips: ELF 32-bit MSB mips-3 executable, MIPS R3000_BE, version 1 (SYSV), statically linked, not stripped
135 $ <b>gxemul -q -E testmips hello_mips</b>
136 Hello world
137 </pre>
138
139 <p>
140 As you can see above, a GCC configured for mips64-unknown-elf can produce
141 both 64-bit and 32-bit binaries. If you don't want to run the entire
142 Hello World program, but want to single-step through the execution to
143 learn more about how MIPS programs run, then add -V to the command line:
144
145 <p>

193
194 GXemul also has an experimental PowerPC emulation mode.
195 <a href="hello_ppc.c">hello_ppc.c</a> is similar to hello_mips.c, but
196 should be compiled and run as follows:
197 <p>
198 <pre>

209 [&nbsp;2005-02-18: I haven't yet been able to build a GCC for ppc64 (only the
210 binutils toolchain), because the gcc sources seem to include Linux header files
211 that aren't present on my FreeBSD system. 32-bit PPC works ok, though.&nbsp;]

364 <p>
365 While these devices may resemble real-world hardware, they are
366 intentionally made simpler to use. (An exception is the framebuffer;
367 some machines actually have simple linear framebuffers like this.)
368
369 <p>
370 If the physical address is 0x10000000, then for MIPS that means that it
371 can be accessed at virtual address 0xffffffffb0000000. (Actually it can be
372 accessed at 0xffffffff90000000 too, but devices should usually be accessed
373 in a non-cached manner.)
374
375 <p>
376 (When using the PPC test machine, "testppc", the addresses are
377 0x10000000, 0x11000000 etc., so no need to add any virtual displacement.)
378
379 <p>
380 The <b>mp</b> device is agnostic when it comes to
381 word-length. For example, when reading offset 0x0000 of the <b>mp</b>
382 device, you may use any kind of read (an 8-bit read will work just as well
383 as a 64-bit read, although the value will be truncated to 8 bits in the
384 first case).
385
386 <p>
387 The <b>cons</b> device should be accessed using 8-bit reads and writes.
388 Doing a getchar() (ie reading from offset 0x0000) returns 0x00 if no
389 character was available.
390
391 <p>
392 On MIPS, the <b>cons</b> device is hardwired to interrupt 2 (the lowest
393 hardware interrupt). Whenever a character is available, the interrupt is
394 asserted. When there are no more available characters, the interrupt is
395 deasserted. (Remember that the interrupt has to be enabled in the status

441 <li>Linux for DECstation:
442 <br>Here is a Debian package containing a Linux 2.4.26 kernel for
443 DECstation which supports framebuffer!

445 <br>kernel-image-2.4.26-r3k-kn02_2.4.26-0.040505.1_mipsel.deb</a>
446 <br>Run the following commands to extract the kernel:<pre>

449 <b>mv boot/vmlinux-* .; rmdir boot</b>
450 </pre>
451 <br>To try with the framebuffer: <b>-E dec -e 3max -X vmlinux-2.4.26-r3k-kn02</b>
452 <br>To try with serial console: <b>-E dec -e 3max -o 'console=ttyS3' vmlinux-2.4.26-r3k-kn02</b>
453 <br>Read <a href="guestoses.html#declinux">this section</a> about how to run a Debian Linux install kernel.
