++ trunk/HISTORY (local) $Id: HISTORY,v 1.1121 2006/02/18 21:03:08 debug Exp $ 20051126 Cobalt and PReP now work with the 21143 NIC. Continuing on Alpha dyntrans things. Fixing some more left-shift-by-24 to unsigned. 20051127 Working on OpenFirmware emulation; major cleanup/redesign. Progress on MacPPC emulation: NetBSD detects two CPUs (when running with -n 2), framebuffer output (for text) works. Adding quick-hack Bandit PCI controller and "gc" interrupt controller for MacPPC. 20051128 Changing from a Bandit to a Uni-North controller for macppc. Continuing on OpenFirmware and MacPPC emulation in general (obio controller, and wdc attached to the obio seems to work). 20051129 More work on MacPPC emulation (adding a dummy ADB controller). Continuing the PCI bus cleanup (endianness and tag composition) and rewriting all PCI controllers' access functions. 20051130 Various minor PPC dyntrans optimizations. Manually inlining some parts of the framebuffer redraw routine. Slowly beginning the conversion of the old MIPS emulation into dyntrans (but this will take quite some time to get right). Generalizing quick_pc_to_pointers. 20051201 Documentation update (David Muse has made available a kernel which simplifies Debian/DECstation installation). Continuing on the ADB bus controller. 20051202 Beginning a rewrite of the Zilog serial controller (dev_zs). 20051203 Continuing on the zs rewrite (now called dev_z8530); conversion to devinit style. Reworking some of the input-only vs output-only vs input-output details of src/console.c, better warning messages, and adding a debug dump. Removing the concept of "device state"; it wasn't really used. Changing some debug output (-vv should now be used to show all details about devices and busses; not shown during normal startup anymore). Beginning on some SPARC instruction disassembly support. 20051204 Minor PPC updates (WALNUT skeleton stuff). Continuing on the MIPS dyntrans rewrite. More progress on the ADB controller (a keyboard is "detected" by NetBSD and OpenBSD). Downgrading OpenBSD/arc as a guest OS from "working" to "almost working" in the documentation. Progress on Algor emulation ("v3" PCI controller). 20051205 Minor updates. 20051207 Sorting devices according to address; this reduces complexity of device lookups from O(n) to O(log n) in memory_rw (but no real performance increase (yet) in experiments). 20051210 Beginning the work on native dyntrans backends (by making a simple skeleton; so far only for Alpha hosts). 20051211 Some very minor SPARC updates. 20051215 Fixing a bug in the MIPS mul (note: not mult) instruction, so it also works with non-64-bit emulation. (Thanks to Alec Voropay for noticing the problem.) 20051216 More work on the fake/empty/simple/skeleton/whatever backend; performance doesn't increase, so this isn't really worth it, but it was probably worth it to prepare for a real backend later. 20051219 More instr call statistics gathering and analysis stuff. 20051220 Another fix for MIPS 'mul'. Also converting mul and {d,}cl{o,z} to dyntrans. memory_ppc.c syntax error fix (noticed by Peter Valchev). Beginning to move out machines from src/machine.c into individual files in src/machines (in a way similar to the autodev system for devices). 20051222 Updating the documentation regarding NetBSD/pmax 3.0. 20051223 - " - NetBSD/cats 3.0. 20051225 - " - NetBSD/hpcmips 3.0. 20051226 Continuing on the machine registry redesign. Adding support for ARM rrx (33-bit rotate). Fixing some signed/unsigned issues (exposed by gcc -W). 20051227 Fixing the bug which prevented a NetBSD/prep 3.0 install kernel from starting (triggered when an mtmsr was the last instruction on a page). Unfortunately not enough to get the kernel to run as well as the 2.1 kernels did. 20051230 Some dyntrans refactoring. 20051231 Continuing on the machine registry redesign. 20060101-10 Continuing... moving more machines. Moving MD interrupt stuff from machine.c into a new src/machines/interrupts.c. 20060114 Adding various mvmeppc machine skeletons. 20060115 Continuing on mvme* stuff. NetBSD/mvmeppc prints boot messages (for MVME1600) and reaches the root device prompt, but no specific hardware devices are emulated yet. 20060116 Minor updates to the mvme1600 emulation mode; the Eagle PCI bus seems to work without much modification, and a 21143 can be detected, interrupts might work (but untested so far). Adding a fake MK48Txx (mkclock) device, for NetBSD/mvmeppc. 20060121 Adding an aux control register for ARM. (A BIG thank you to Olivier Houchard for tracking down this bug.) 20060122 Adding more ARM instructions (smulXY), and dev_iq80321_7seg. 20060124 Adding disassembly of more ARM instructions (mia*, mra/mar), and some semi-bogus XScale and i80321 registers. 20060201-02 Various minor updates. Moving the last machines out of machine.c. 20060204 Adding a -c command line option, for running debugger commands before the simulation starts, but after all files have been loaded. Minor iq80321-related updates. 20060209 Minor hacks (DEVINIT macro, etc). Preparing for the generalization of the 64-bit dyntrans address translation subsystem. 20060216 Adding ARM ldrd (double-register load). 20060217 Continuing on various ARM-related stuff. 20060218 More progress on the ATA/wdc emulation for NetBSD/iq80321. NetBSD/evbarm can now be installed :-) Updating the docs, etc. Continuing on Algor emulation. ============== RELEASE 0.3.8 ==============
++ trunk/HISTORY (local) $Id: HISTORY,v 1.707 2005/04/27 16:37:33 debug Exp $ 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. ============== RELEASE 0.3.2 ==============
