++ trunk/HISTORY (local) $Id: HISTORY,v 1.772 2005/06/04 12:02:16 debug Exp $ 20050428 Disabling the "-fmove-all-movables" option in the configure script, because it causes the compile to fail on OpenBSD/sgi. 20050502 Minor updates. 20050503 Removing the WRT54G mode (it was bogus anyway), and adding a comment about Windows NT for MIPS in doc/experiments.html. Minor updates to the x86 instruction decoding. 20050504 Adding some more x86 instructions. Adding support for reading files from ISO9660 CDROMs (including gzipped files). It's an ugly hack, but it seems to work. Various other minor updates (dev_vga.c, pc_bios.c etc). 20050505 Some more x86-related updates. Beginning (what I hope will be) a major code cleanup phase. "bootris" (an x86 bootsector) runs :-) 20050506 Adding some more x86 instructions. 20050507 tmpnam => mkstemp. Working on a hack to allow VGA charcells to be shown even when not running with X11. Adding more x86 instructions. 20050508 x86 32-bit SIB addressing fix, and more instructions. 20050509 Adding more x86 instructions. 20050510 Minor documentation updates, and other updates (x86 stuff etc.) 20050511 More x86-related updates. 20050513 Various updates, mostly x86-related. (Trying to fix flag calculation, factoring out the ugly shift/rotate code, and some other things.) 20050514 Adding support for loading some old i386 a.out executables. Finally beginning the cleanup of machine/PROM/bios dependant info. Some minor documentation updates. Trying to clean up ARCBIOS stuff a little. 20050515 Trying to make it possible to actually use more than one disk type per machine (floppy, ide, scsi). Trying to clean up the kbd vs PROM console stuff. (For PC and ARC emulation modes, mostly.) Beginning to add an 8259 interrupt controller, and connecting it to the x86 emulation. 20050516 The first x86 interrupts seem to work (keyboard stuff). Adding a 8253/8254 programmable interval timer skeleton. FreeDOS now reaches a command prompt and can be interacted with. 20050517 After some bugfixes, MS-DOS also (sometimes) reaches a command prompt now. Trying to fix the pckbc to work with MS-DOS' keyb.com, but no success yet. 20050518 Adding a simple 32-bit x86 MMU skeleton. 20050519 Some more work on the x86 stuff. (Beginning the work on paging, and various other fixes). 20050520 More updates. Working on dev_vga (4-bit graphics modes), adding 40 columns support to the PC bios emulation. Trying to add support for resizing windows when switching between graphics modes. 20050521 Many more x86-related updates. 20050522 Correcting the initial stack pointer's sign-extension for ARCBIOS emulation (thanks to Alec Voropay for noticing the error). Continuing on the cleanup (ARCBIOS etc). dev_vga updates. 20050523 More x86 updates: trying to add some support for protected mode interrupts (via gate descriptors) and many other fixes. More ARCBIOS cleanup. Adding a device flag which indicates that reads cause no side-effects. (Useful for the "dump" command in the debugger, and other things.) Adding support for directly starting up x86 ELFs, skipping the bootloader stage. (Most ELFs, however, are not suitable for this.) 20050524 Adding simple 32-bit x86 TSS task switching, but no privilege level support yet. More work on dev_vga. A small "Copper bars" demo works. :-) Adding support for Trap Flag (single-step exceptions), at least in real mode, and various other x86-related fixes. 20050525 Adding a new disk image prefix (gH;S;) which can be used to override the default nr of heads and sectors per track. 20050527 Various bug fixes, more work on the x86 mode (stack change on interrupts between different priv.levels), and some minor documentation updates. 20050528 Various fixes (x86 stuff). 20050529 More x86 fixes. An OpenBSD/i386 bootfloppy reaches userland and can be interacted with (although there are problems with key repetition). NetBSD/i386 triggers a serious CISC-related problem: instruction fetches across page boundaries, where the later part isn't actually part of the instruction. 20050530 Various minor updates. (Documentation updates, etc.) 20050531 Adding some experimental code (experiments/new_test_*) which could be useful for dynamic (but not binary) translation in the future. 20050602 Adding a dummy ARM skeleton. Fixing the pckbc key repetition problem (by adding release scancodes for all keypresses). 20050603 Minor updates for the next release. 20050604 Release testing. Minor updates. ============== RELEASE 0.3.3 ============== 20050604 There'll probably be a 0.3.3.1 release soon, with some very very tiny updates.
++ 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 ==============
