20060723 More Transputer instructions (pfix, nfix, opr, mint, ldl, ldlp,
eqc, rev, ajw, stl, stlf, sthf, sub, ldnl, ldnlp, ldpi, move,
wcnt, add, bcnt).
Adding more SPARC instructions (andcc, addcc, bl, rdpr).
Progress on the igsfb framebuffer used by NetBSD/netwinder.
Enabling 8-bit fills in dev_fb.
NetBSD/netwinder 3.0.1 can now run from a disk image :-)
20060724 Cleanup/performance fix for 64-bit virtual translation table
updates (by removing the "timestamp" stuff). A full NetBSD/pmax
3.0.1 install for R4400 has dropped from 667 seconds to 584 :)
Fixing the igsfb "almost vga" color (it is 24-bit, not 18-bit).
Adding some MIPS instruction combinations (3*lw, and 3*addu).
The 8048 keyboard now turns off interrupt enable between the
KBR_ACK and the KBR_RSTDONE, to work better with Linux 2.6.
Not causing PPC DEC interrupts if PPC_NO_DEC is set for a
specific CPU; NetBSD/bebox gets slightly further than before.
Adding some more SPARC instructions: branches, udiv.
20060725 Refreshing dev_pckbc.c a little.
Cleanups for the SH emulation mode, and adding the first
"compact" (16-bit) instructions: various simple movs, nop,
shll, stc, or, ldc.
20060726 Adding dummy "pcn" (AMD PCnet NIC) PCI glue.
20060727 Various cleanups; removing stuff from cpu.h, such as
running_translated (not really meaningful anymore), and
page flags (breaking into the debugger clears all translations
anyway).
Minor MIPS instruction combination updates.
20060807 Expanding the 3*sw and 3*lw MIPS instruction combinations to
work with 2* and 4* too, resulting in a minor performance gain.
Implementing a usleep hack for the RM52xx/MIPS32/MIPS64 "wait"
instruction (when emulating 1 cpu).
20060808 Experimenting with some more MIPS instruction combinations.
Implementing support for showing a (hardcoded 12x22) text
cursor in igsfb.
20060809 Simplifying the NetBSD/evbmips (Malta) install instructions
somewhat (by using a NetBSD/pmax ramdisk install kernel).
20060812 Experimenting more with the MIPS 'wait' instruction.
PCI configuration register writes can now be handled, which
allow PCI IDE controllers to work with NetBSD/Malta 3.0.1 and
NetBSD/cobalt 3.0.1. (Previously only NetBSD 2.1 worked.)
20060813 Updating dev_gt.c based on numbers from Alec Voropay, to enable
Linux 2.6 to use PCI on Malta.
Continuing on Algor interrupt stuff.
20060814 Adding support for routing ISA interrupts to two different
interrupts, making it possible to run NetBSD/algor :-)
20060814-15 Testing for the release.

Original Path:
trunk/experiments/test_netbsd_pmax_install.expect
File length: 1003 byte(s)
++ trunk/HISTORY (local)
$Id: HISTORY,v 1.1298 2006/07/22 11:27:46 debug Exp $
20060626 Continuing on SPARC emulation (beginning on the 'save'
instruction, register windows, etc).
20060629 Planning statistics gathering (new -s command line option),
and renaming speed_tricks to allow_instruction_combinations.
20060630 Some minor manual page updates.
Various cleanups.
Implementing the -s command line option.
20060701 FINALLY found the bug which prevented Linux and Ultrix from
running without the ugly hack in the R2000/R3000 cache isol
code; it was the phystranslation hint array which was buggy.
Removing the phystranslation hint code completely, for now.
20060702 Minor dyntrans cleanups; invalidation of physpages now only
invalidate those parts of a page that have actually been
translated. (32 parts per page.)
Some MIPS non-R3000 speed fixes.
Experimenting with MIPS instruction combination for some
addiu+bne+sw loops, and sw+sw+sw.
Adding support (again) for larger-than-4KB pages in MIPS tlbw*.
Continuing on SPARC emulation: adding load/store instructions.
20060704 Fixing a virtual vs physical page shift bug in the new tlbw*
implementation. Problem noticed by Jakub Jermar. (Many thanks.)
Moving rfe and eret to cpu_mips_instr.c, since that is the
only place that uses them nowadays.
20060705 Removing the BSD license from the "testmachine" include files,
placing them in the public domain instead; this enables the
testmachine stuff to be used from projects which are
incompatible with the BSD license for some reason.
20060707 Adding instruction combinations for the R2000/R3000 L1
I-cache invalidation code used by NetBSD/pmax 3.0, lui+addiu,
various branches followed by addiu or nop, and jr ra followed
by addiu. The time it takes to perform a full NetBSD/pmax R3000
install on the laptop has dropped from 573 seconds to 539. :-)
20060708 Adding a framebuffer controller device (dev_fbctrl), which so
far can be used to change the fb resolution during runtime, but
in the future will also be useful for accelerated block fill/
copy, and possibly also simplified character output.
Adding an instruction combination for NetBSD/pmax' strlen.
20060709 Minor fixes: reading raw files in src/file.c wasn't memblock
aligned, removing buggy multi_sw MIPS instruction combination,
etc.
20060711 Adding a machine_qemu.c, which contains a "qemu_mips" machine.
(It mimics QEMU's MIPS machine mode, so that a test kernel
made for QEMU_MIPS also can run in GXemul... at least to some
extent.) Adding a short section about how to run this mode to
doc/guestoses.html.
20060714 Misc. minor code cleanups.
20060715 Applying a patch which adds getchar() to promemul/yamon.c
(from Oleksandr Tymoshenko).
Adding yamon.h from NetBSD, and rewriting yamon.c to use it
(instead of ugly hardcoded numbers) + some cleanup.
20060716 Found and fixed the bug which broke single-stepping of 64-bit
programs between 0.4.0 and 0.4.0.1 (caused by too quick
refactoring and no testing). Hopefully this fix will not
break too many other things.
20060718 Continuing on the 8253 PIT; it now works with Linux/QEMU_MIPS.
Re-adding the sw+sw+sw instr comb (the problem was that I had
ignored endian issues); however, it doesn't seem to give any
big performance gain.
20060720 Adding a dummy Transputer mode (T414, T800 etc) skeleton (only
the 'j' and 'ldc' instructions are implemented so far). :-}
20060721 Adding gtreg.h from NetBSD, updating dev_gt.c to use it, plus
misc. other updates to get Linux 2.6 for evbmips/malta working
(thanks to Alec Voropay for the details).
FINALLY found and fixed the bug which made tlbw* for non-R3000
buggy; it was a reference count problem in the dyntrans core.
20060722 Testing stuff; things seem stable enough for a new release.
