emulators/gxemul,
Framework for full-system computer architecture emulation
Branch: CURRENT,
Version: 0.7.0nb2,
Package name: gxemul-0.7.0nb2,
Maintainer: pkgsrc-usersGXemul is a framework for full-system computer architecture emulation.
Several processor architectures and machine types have been implemented.
It is working well enough to allow unmodified "guest" operating systems to
run inside the emulator, as if they were running on real hardware.
The emulator emulates (networks of) real machines. The machines may consist
of ARM, MIPS, Motorola 88K, PowerPC, and SuperH processors, and various
surrounding hardware components such as framebuffers, busses, interrupt
controllers, ethernet controllers, disk controllers, and serial port
controllers.
GXemul, including the dynamic translation system, is implemented in portable
C++, which means that the emulator will (at least in theory) run on
practically any modern host architecture and unix-like operating system, for
which a C++ compiler is available.
The documentation lists the machines and specific guest operating systems
that can be regarded as "working" in GXemul. The guest operating system
that works best in GXemul is NetBSD/pmax.

emulators: Remove SHA1 hashes for distfiles

Log message:
gxemul: update to 0.7.0.
ChangeLog:
20210228 Switching back from C++ to plain C.
Implementing a helper method for registering device addresses
as symbols (so that it can be used from several machines).
20210307 Subtle colorized output when stdin/stdout are connected to a
tty, to make it quicker to interpret text output. Enabled with
-G or by setting the CLICOLOR environment variable. Can be
disabled with -A.
20210309 Beginning to separate debug messages into subsystems, that have
individual verbosity levels.
Making -K work more consistently (enter the debugger at the
end of a run). -V implies -K.
Making -T work better for M88K (breaking into the debugger
directly on bad memory accesses, if -K is used).
20210310 All MIPS machines now register their devices as symbols (based
in kseg1, i.e. 0xffffffffa0000000).
20210311 Making -T work better for MIPS, PPC, ARM, and SuperH.
20210314 Adding a -L command line option for enabling tap networking
without using configuration files.
-x is now needed if one wants separate xterm windows for serial
I/O when using configuration files with a single machine.
20210316 debugmsg subsystems can now be registered at runtime; this is
so far done from the Lance Ethernet device.
Adding a 'verbosity' debugger command for inspecting and
setting the verbosity level for individual subsystems.
20210318 Fixing an annoying 'backspace' bug in the debugger command
line handling, where the response sometimes could become
"unknown command ''".
Implementing CTRL-W (erase word) in the debugger.
Implementing CTRL-T (SIGINFO-like status line) in the debugger.
20210320 Removing the UNSTABLE_DEVEL configure define; it was not used
much, and the debugmsg verbosity levels can be used in its
place.
Fixing a bug for MIPS R2000/R3000 when writing to coprocessor 0
"entrylo" register (if the lowest 8 bits were 0, the code took
the non-R2000/R3000 code path).
20210321 Adding an empty i960 CPU skeleton [again].
Moving 'arch' from struct machine to struct cpu; in the future,
perhaps this would allow a machine to have heterogenous CPU
sets (such as the Dreamcast with both SuperH and ARM).
Removing "slow_serial_interrupts_hack_for_linux" (-U) command
line option, since it is not used for most guest OSes, and
occupied a command line option char.
20210323 Breaking out the mb89352 SCSI Protocol Controller from the
luna88k device, and beginning to implement it. Works well
enough for OpenBSD's "boot" to read the disk and load the
kernel, but not well enough for the kernel to like it.
20210324 Adding support for 00 99 01 07 variant of luna88k a.out.
20210325 The mb89352 SCSI controller uses its own subsystem for debug
messages.
20210327 Adding an empty RISC-V CPU skeleton [again].
Implementing enough of the mb89352 to allow OpenBSD/luna88k
to boot with SCSI (both the boot loader and the kernel)!
20210401 Applying a patch from George Matsumura to make things build
better on Linux: __attribute__((__packed__)); in bootblock.h.
20210405 Adding hardcoded boot_unit=0 and boot_partition=0 NVRAM
variables to the LUNA-88K machine, allowing OpenBSD/luna88k
to boot from disk without asking for root and swap partitions.
Adding 'R' (upper-case) disk image prefix, as a shorthand for
creating temporary overlays.
20210407 Code for idling the host processor has been moved out from
individual CPU implementations to the main emul loop.
Implementing an X11 mouse pointer grab mechanism. Grab is
activated by clicking in a framebuffer window, and released
using left CTRL + ALT. When grab is active, the host mouse
cursor is hidden and the window caption changes to indicate
that grab is active.
20210408 Implementing an unusual 88K "not_maxneg_nor_zero" bcnd
condition.
20210409 Moving the LUNA88K framebuffer to its own device file.
Beginning to implement the LUNA88K front panel LCD.
Also fixing a bug where the rightmost pixel (or 8 pixels in
the case of monochrome) were not drawn.
20210410 Also check for X11R7 in the configure script, in addition
to X11R6.
20210417 Porting over i960CA disassembly from the C++ framework.
20210418 More i960 stuff, including re-adding the (so far dummy)
Cyclone VH machine.
Assuming availabilty of __func__ (C99 standard).
20210422 Enabling idle detection for OpenBSD/luna88k, which uses a
bcnd.n instruction. A hack, but it seems to work.
Fixing a bug where console input could randomly be lost when
idling, if there were multiple emulated serial ports.

Log message:
gxemul: Update to 0.6.3.1
Changelog:
20210215 Implementing the fadd.dss 88K instruction, and working a bit
more on the exception cases in the xmem instruction.
20210220 Implementing mouse emulation support for the LUNA88K machine.
Updating OpenBSD/sgi install instructions (6.5 -> 6.8),
and including a screenshot of X11 running.
20210221 Handle return values from interrupted select() when checking
for available console input. (Found when using CTRL-C on Linux
to enter the debugger command line, and noticed that it was
spuriously broken.)
20210222 Basic multiprocessor bootup of OpenBSD/luna88k now works, but
it is slightly unstable.
