++ trunk/HISTORY (local) $Id: HISTORY,v 1.1613 2007/06/15 20:11:26 debug Exp $ 20070501 Continuing a little on m88k disassembly (control registers, more instructions). Adding a dummy mvme88k machine mode. 20070502 Re-adding MIPS load/store alignment exceptions. 20070503 Implementing more of the M88K disassembly code. 20070504 Adding disassembly of some more M88K load/store instructions. Implementing some relatively simple M88K instructions (br.n, xor[.u] imm, and[.u] imm). 20070505 Implementing M88K three-register and, or, xor, and jmp[.n], bsr[.n] including function call trace stuff. Applying a patch from Bruce M. Simpson which implements the SYSCON_BOARD_CPU_CLOCK_FREQ_ID object of the syscon call in the yamon PROM emulation. 20070506 Implementing M88K bb0[.n] and bb1[.n], and skeletons for ldcr and stcr (although no control regs are implemented yet). 20070509 Found and fixed the bug which caused Linux for QEMU_MIPS to stop working in 0.4.5.1: It was a faulty change to the MIPS 'sc' and 'scd' instructions I made while going through gcc -W warnings on 20070428. 20070510 Updating the Linux/QEMU_MIPS section in guestoses.html to use mips-test-0.2.tar.gz instead of 0.1. A big thank you to Miod Vallat for sending me M88K manuals. Implementing more M88K instructions (addu, subu, div[u], mulu, ext[u], clr, set, cmp). 20070511 Fixing bugs in the M88K "and" and "and.u" instructions (found by comparing against the manual). Implementing more M88K instructions (mask[.u], mak, bcnd (auto- generated)) and some more control register details. Cleanup: Removing the experimental AVR emulation mode and corresponding devices; AVR emulation wasn't really meaningful. Implementing autogeneration of most M88K loads/stores. The rectangle drawing demo (with -O0) for M88K runs :-) Beginning on M88K exception handling. More M88K instructions: tb0, tb1, rte, sub, jsr[.n]. Adding some skeleton MVME PROM ("BUG") emulation. 20070512 Fixing a bug in the M88K cmp instruction. Adding the M88K lda (scaled register) instruction. Fixing bugs in 64-bit (32-bit pairs) M88K loads/stores. Removing the unused tick_hz stuff from the machine struct. Implementing the M88K xmem instruction. OpenBSD/mvme88k gets far enough to display the Copyright banner :-) Implementing subu.co (guess), addu.co, addu.ci, ff0, and ff1. Adding a dev_mvme187, for MVME187-specific devices/registers. OpenBSD/mvme88k prints more boot messages. :) 20070515 Continuing on MVME187 emulation (adding more devices, beginning on the CMMUs, etc). Adding the M88K and.c, xor.c, and or.c instructions, and making sure that mul, div, etc cause exceptions if executed when SFD1 is disabled. 20070517 Continuing on M88K and MVME187 emulation in general; moving the CMMU registers to the CPU struct, separating dev_pcc2 from dev_mvme187, and beginning on memory_m88k.c (BATC and PATC). Fixing a bug in 64-bit (32-bit pairs) M88K fast stores. Implementing the clock part of dev_mk48txx. Implementing the M88K fstcr and xcr instructions. Implementing m88k_cpu_tlbdump(). Beginning on the implementation of a separate address space for M88K .usr loads/stores. 20070520 Removing the non-working (skeleton) Sandpoint, SonyNEWS, SHARK Dnard, and Zaurus machine modes. Experimenting with dyntrans to_be_translated read-ahead. It seems to give a very small performance increase for MIPS emulation, but a large performance degradation for SuperH. Hm. 20070522 Disabling correct SuperH ITLB emulation; it does not seem to be necessary in order to let SH4 guest OSes run, and it slows down userspace code. Implementing "samepage" branches for SuperH emulation, and some other minor speed hacks. 20070525 Continuing on M88K memory-related stuff: exceptions, memory transaction register contents, etc. Implementing the M88K subu.ci instruction. Removing the non-working (skeleton) Iyonix machine mode. OpenBSD/mvme88k reaches userland :-), starts executing /sbin/init's instructions, and issues a few syscalls, before crashing. 20070526 Fixing bugs in dev_mk48txx, so that OpenBSD/mvme88k detects the correct time-of-day. Implementing a generic IRQ controller for the test machines (dev_irqc), similar to a proposed patch from Petr Stepan. Experimenting some more with translation read-ahead. Adding an "expect" script for automated OpenBSD/landisk install regression/performance tests. 20070527 Adding a dummy mmEye (SH3) machine mode skeleton. FINALLY found the strange M88K bug I have been hunting: I had not emulated the SNIP value for exceptions occurring in branch delay slots correctly. Implementing correct exceptions for 64-bit M88K loads/stores. Address to symbol lookups are now disabled when M88K is running in usermode (because usermode addresses don't have anything to do with supervisor addresses). 20070531 Removing the mmEye machine mode skeleton. 20070604 Some minor code cleanup. 20070605 Moving src/useremul.c into a subdir (src/useremul/), and cleaning up some more legacy constructs. Adding -Wstrict-aliasing and -fstrict-aliasing detection to the configure script. 20070606 Adding a check for broken GCC on Solaris to the configure script. (GCC 3.4.3 on Solaris cannot handle static variables which are initialized to 0 or NULL. :-/) Removing the old (non-working) ARC emulation modes: NEC RD94, R94, R96, and R98, and the last traces of Olivetti M700 and Deskstation Tyne. Removing the non-working skeleton WDSC device (dev_wdsc). 20070607 Thinking about how to use the host's cc + ld at runtime to generate native code. (See experiments/native_cc_ld_test.i for an example.) 20070608 Adding a program counter sampling timer, which could be useful for native code generation experiments. The KN02_CSR_NRMMOD bit in the DECstation 5000/200 (KN02) CSR should always be set, to allow a 5000/200 PROM to boot. 20070609 Moving out breakpoint details from the machine struct into a helper struct, and removing the limit on max nr of breakpoints. 20070610 Moving out tick functions into a helper struct as well (which also gets rid of the max limit). 20070612 FINALLY figured out why Debian/DECstation stopped working when translation read-ahead was enabled: in src/memory_rw.c, the call to invalidate_code_translation was made also if the memory access was an instruction load (if the page was mapped as writable); it shouldn't be called in that case. 20070613 Implementing some more MIPS32/64 revision 2 instructions: di, ei, ext, dext, dextm, dextu, and ins. 20070614 Implementing an instruction combination for the NetBSD/arm idle loop (making the host not use any cpu if NetBSD/arm inside the emulator is not using any cpu). Increasing the nr of ARM VPH entries from 128 to 384. 20070615 Removing the ENABLE_arch stuff from the configure script, so that all included architectures are included in both release and development builds. Moving memory related helper functions from misc.c to memory.c. Adding preliminary instructions for netbooting NetBSD/pmppc to guestoses.html; it doesn't work yet, there are weird timeouts. Beginning a total rewrite of the userland emulation modes (removing all emulation modes, beginning from scratch with NetBSD/MIPS and FreeBSD/Alpha only). 20070616 After fixing a bug in the DEC21143 NIC (the TDSTAT_OWN bit was only cleared for the last segment when transmitting, not all segments), NetBSD/pmppc boots with root-on-nfs without the timeouts. Updating guestoses.html. Removing the skeleton PSP (Playstation Portable) mode. Moving X11-related stuff in the machine struct into a helper struct. Cleanup of out-of-memory checks, to use a new CHECK_ALLOCATION macro (which prints a meaningful error message). Adding a COMMENT to each machine and device (for automagic .index comment generation). Doing regression testing for the next release. ============== RELEASE 0.4.6 ==============
++ trunk/HISTORY (local) $Id: HISTORY,v 1.1480 2007/02/19 01:34:42 debug Exp $ 20061029 Changing usleep(1) calls in the debugger to usleep(10000) 20061107 Adding a new disk image option (-d o...) which sets the ISO9660 filesystem base offset; also making some other hacks to allow NetBSD/dreamcast and homebrew demos/games to boot directly from a filesystem image. Moving Dreamcast-specific stuff in the documentation to its own page (dreamcast.html). Adding a border to the Dreamcast PVR framebuffer. 20061108 Adding a -T command line option (again?), for halting the emulator on unimplemented memory accesses. 20061109 Continuing on various SH4 and Dreamcast related things. The emulator should now halt on more unimplemented device accesses, instead of just printing a warning, forcing me to actually implement missing stuff :) 20061111 Continuing on SH4 and Dreamcast stuff. Adding a bogus Landisk (SH4) machine mode. 20061112 Implementing some parts of the Dreamcast GDROM device. With some ugly hacks, NetBSD can (barely) mount an ISO image. 20061113 NetBSD/dreamcast now starts booting from the Live CD image, but crashes randomly quite early on in the boot process. 20061122 Beginning on a skeleton interrupt.h and interrupt.c for the new interrupt subsystem. 20061124 Continuing on the new interrupt system; taking the first steps to attempt to connect CPUs (SuperH and MIPS) and devices (dev_cons and SH4 timer interrupts) to it. Many things will probably break from now on. 20061125 Converting dev_ns16550, dev_8253 to the new interrupt system. Attempting to begin to convert the ISA bus. 20061130 Incorporating a patch from Brian Foley for the configure script, which checks for X11 libs in /usr/X11R6/lib64 (which is used on some Linux systems). 20061227 Adding a note in the man page about booting from Dreamcast CDROM images (i.e. that no external kernel is needed). 20061229 Continuing on the interrupt system rewrite: beginning to convert more devices, adding abort() calls for legacy interrupt system calls so that everything now _has_ to be rewritten! Almost all machine modes are now completely broken. 20061230 More progress on removing old interrupt code, mostly related to the ISA bus + devices, the LCA bus (on AlphaBook1), and the Footbridge bus (for CATS). And some minor PCI stuff. Connecting the ARM cpu to the new interrupt system. The CATS, NetWinder, and QEMU_MIPS machine modes now work with the new interrupt system :) 20061231 Connecting PowerPC CPUs to the new interrupt system. Making PReP machines (IBM 6050) work again. Beginning to convert the GT PCI controller (for e.g. Malta and Cobalt emulation). Some things work, but not everything. Updating Copyright notices for 2007. 20070101 Converting dev_kn02 from legacy style to devinit; the 3max machine mode now works with the new interrupt system :-] 20070105 Beginning to convert the SGI O2 machine to the new interrupt system; finally converting O2 (IP32) devices to devinit, etc. 20070106 Continuing on the interrupt system redesign/rewrite; KN01 (PMAX), KN230, and Dreamcast ASIC interrupts should work again, moving out stuff from machine.h and devices.h into the corresponding devices, beginning the rewrite of i80321 interrupts, etc. 20070107 Beginning on the rewrite of Eagle interrupt stuff (PReP, etc). 20070117 Beginning the rewrite of Algor (V3) interrupts (finally changing dev_v3 into devinit style). 20070118 Removing the "bus" registry concept from machine.h, because it was practically meaningless. Continuing on the rewrite of Algor V3 ISA interrupts. 20070121 More work on Algor interrupts; they are now working again, well enough to run NetBSD/algor. :-) 20070122 Converting VR41xx (HPCmips) interrupts. NetBSD/hpcmips can be installed using the new interrupt system :-) 20070123 Making the testmips mode work with the new interrupt system. 20070127 Beginning to convert DEC5800 devices to devinit, and to the new interrupt system. Converting Playstation 2 devices to devinit, and converting the interrupt system. Also fixing a severe bug: the interrupt mask register on Playstation 2 is bitwise _toggled_ on writes. 20070128 Removing the dummy NetGear machine mode and the 8250 device (which was only used by the NetGear machine). Beginning to convert the MacPPC GC (Grand Central) interrupt controller to the new interrupt system. Converting Jazz interrupts (PICA61 etc.) to the new interrupt system. NetBSD/arc can be installed again :-) Fixing the JAZZ timer (hardcoding it at 100 Hz, works with NetBSD and it is better than a completely dummy timer as it was before). Converting dev_mp to the new interrupt system, although I haven't had time to actually test it yet. Completely removing src/machines/interrupts.c, cpu_interrupt and cpu_interrupt_ack in src/cpu.c, and src/include/machine_interrupts.h! Adding fatal error messages + abort() in the few places that are left to fix. Converting dev_z8530 to the new interrupt system. FINALLY removing the md_int struct completely from the machine struct. SH4 fixes (adding a PADDR invalidation in the ITLB replacement code in memory_sh.c); the NetBSD/dreamcast LiveCD now runs all the way to the login prompt, and can be interacted with :-) Converting the CPC700 controller (PCI and interrupt controller for PM/PPC) to the new interrupt system. 20070129 Fixing MACE ISA interrupts (SGI IP32 emulation). Both NetBSD/ sgimips' and OpenBSD/sgi's ramdisk kernels can now be interacted with again. 20070130 Moving out the MIPS multi_lw and _sw instruction combinations so that they are auto-generated at compile time instead. 20070131 Adding detection of amd64/x86_64 hosts in the configure script, for doing initial experiments (again :-) with native code generation. Adding a -k command line option to set the size of the dyntrans cache, and a -B command line option to disable native code generation, even if GXemul was compiled with support for native code generation for the specific host CPU architecture. 20070201 Experimenting with a skeleton for native code generation. Changing the default behaviour, so that native code generation is now disabled by default, and has to be enabled by using -b on the command line. 20070202 Continuing the native code generation experiments. Making PCI interrupts work for Footbridge again. 20070203 More native code generation experiments. Removing most of the native code generation experimental code, it does not make sense to include any quick hacks like this. Minor cleanup/removal of some more legacy MIPS interrupt code. 20070204 Making i80321 interrupts work again (for NetBSD/evbarm etc.), and fixing the timer at 100 Hz. 20070206 Experimenting with removing the wdc interrupt slowness hack. 20070207 Lowering the number of dyntrans TLB entries for MIPS from 192 to 128, resulting in a minor speed improvement. Minor optimization to the code invalidation routine in cpu_dyntrans.c. 20070208 Increasing (experimentally) the nr of dyntrans instructions per loop from 60 to 120. 20070210 Commenting out (experimentally) the dyntrans_device_danger detection in memory_rw.c. Changing the testmips and baremips machines to use a revision 2 MIPS64 CPU by default, instead of revision 1. Removing the dummy i960, IA64, x86, AVR32, and HP PA-RISC files, the PC bios emulation, and the Olivetti M700 (ARC) and db64360 emulation modes. 20070211 Adding an "mp" demo to the demos directory, which tests the SMP functionality of the testmips machine. Fixing PReP interrupts some more. NetBSD/prep now boots again. 20070216 Adding a "nop workaround" for booting Mach/PMAX to the documentation; thanks to Artur Bujdoso for the values. Converting more of the MacPPC interrupt stuff to the new system. Beginning to convert BeBox interrupts to the new system. PPC603e should NOT have the PPC_NO_DEC flag! Removing it. Correcting BeBox clock speed (it was set to 100 in the NetBSD bootinfo block, but should be 33000000/4), allowing NetBSD to start without using the (incorrect) PPC_NO_DEC hack. 20070217 Implementing (slow) AltiVec vector loads and stores, allowing NetBSD/macppc to finally boot using the GENERIC kernel :-) Updating the documentation with install instructions for NetBSD/macppc. 20070218-19 Regression testing for the release. ============== RELEASE 0.4.4 ==============
++ trunk/HISTORY (local) $Id: HISTORY,v 1.1421 2006/11/06 05:32:37 debug Exp $ 20060816 Adding a framework for emulated/virtual timers (src/timer.c), using only setitimer(). Rewriting the mc146818 to use the new timer framework. 20060817 Adding a call to gettimeofday() every now and then (once every second, at the moment) to resynch the timer if it drifts. Beginning to convert the ISA timer interrupt mechanism (8253 and 8259) to use the new timer framework. Removing the -I command line option. 20060819 Adding the -I command line option again, with new semantics. Working on Footbridge timer interrupts; NetBSD/NetWinder and NetBSD/CATS now run at correct speed, but unfortunately with HUGE delays during bootup. 20060821 Some minor m68k updates. Adding the first instruction: nop. :) Minor Alpha emulation updates. 20060822 Adding a FreeBSD development specific YAMON environment variable ("khz") (as suggested by Bruce M. Simpson). Moving YAMON environment variable initialization from machine_evbmips.c into promemul/yamon.c, and adding some more variables. Continuing on the LCA PCI bus controller (for Alpha machines). 20060823 Continuing on the timer stuff: experimenting with MIPS count/ compare interrupts connected to the timer framework. 20060825 Adding bogus SCSI commands 0x51 (SCSICDROM_READ_DISCINFO) and 0x52 (SCSICDROM_READ_TRACKINFO) to the SCSI emulation layer, to allow NetBSD/pmax 4.0_BETA to be installed from CDROM. Minor updates to the LCA PCI controller. 20060827 Implementing a CHIP8 cpu mode, and a corresponding CHIP8 machine, for fun. Disassembly support for all instructions, and most of the common instructions have been implemented: mvi, mov_imm, add_imm, jmp, rand, cls, sprite, skeq_imm, jsr, skne_imm, bcd, rts, ldr, str, mov, or, and, xor, add, sub, font, ssound, sdelay, gdelay, bogus skup/skpr, skeq, skne. 20060828 Beginning to convert the CHIP8 cpu in the CHIP8 machine to a (more correct) RCA 180x cpu. (Disassembly for all 1802 instructions has been implemented, but no execution yet, and no 1805 extended instructions.) 20060829 Minor Alpha emulation updates. 20060830 Beginning to experiment a little with PCI IDE for SGI O2. Fixing the cursor key mappings for MobilePro 770 emulation. Fixing the LK201 warning caused by recent NetBSD/pmax. The MIPS R41xx standby, suspend, and hibernate instructions now behave like the RM52xx/MIPS32/MIPS64 wait instruction. Fixing dev_wdc so it calculates correct (64-bit) offsets before giving them to diskimage_access(). 20060831 Continuing on Alpha emulation (OSF1 PALcode). 20060901 Minor Alpha updates; beginning on virtual memory pagetables. Removed the limit for max nr of devices (in preparation for allowing devices' base addresses to be changed during runtime). Adding a hack for MIPS [d]mfc0 select 0 (except the count register), so that the coproc register is simply copied. The MIPS suspend instruction now exits the emulator, instead of being treated as a wait instruction (this causes NetBSD/ hpcmips to get correct 'halt' behavior). The VR41xx RTC now returns correct time. Connecting the VR41xx timer to the timer framework (fixed at 128 Hz, for now). Continuing on SPARC emulation, adding more instructions: restore, ba_xcc, ble. The rectangle drawing demo works :) Removing the last traces of the old ENABLE_CACHE_EMULATION MIPS stuff (not usable with dyntrans anyway). 20060902 Splitting up src/net.c into several smaller files in its own subdirectory (src/net/). 20060903 Cleanup of the files in src/net/, to make them less ugly. 20060904 Continuing on the 'settings' subsystem. Minor progress on the SPARC emulation mode. 20060905 Cleanup of various things, and connecting the settings infrastructure to various subsystems (emul, machine, cpu, etc). Changing the lk201 mouse update routine to not rely on any emulated hardware framebuffer cursor coordinates, but instead always do (semi-usable) relative movements. 20060906 Continuing on the lk201 mouse stuff. Mouse behaviour with multiple framebuffers (which was working in Ultrix) is now semi-broken (but it still works, in a way). Moving the documentation about networking into its own file (networking.html), and refreshing it a bit. Adding an example of how to use ethernet frame direct-access (udp_snoop). 20060907 Continuing on the settings infrastructure. 20060908 Minor updates to SH emulation: for 32-bit emulation: delay slots and the 'jsr @Rn' instruction. I'm putting 64-bit SH5 on ice, for now. 20060909-10 Implementing some more 32-bit SH instructions. Removing the 64-bit mode completely. Enough has now been implemented to run the rectangle drawing demo. :-) 20060912 Adding more SH instructions. 20060916 Continuing on SH emulation (some more instructions: div0u, div1, rotcl/rotcr, more mov instructions, dt, braf, sets, sett, tst_imm, dmuls.l, subc, ldc_rm_vbr, movt, clrt, clrs, clrmac). Continuing on the settings subsystem (beginning on reading/ writing settings, removing bugs, and connecting more cpus to the framework). 20060919 More work on SH emulation; adding an ldc banked instruction, and attaching a 640x480 framebuffer to the Dreamcast machine mode (NetBSD/dreamcast prints the NetBSD copyright banner :-), and then panics). 20060920 Continuing on the settings subsystem. 20060921 Fixing the Footbridge timer stuff so that NetBSD/cats and NetBSD/netwinder boot up without the delays. 20060922 Temporarily hardcoding MIPS timer interrupt to 100 Hz. With 'wait' support disabled, NetBSD/malta and Linux/malta run at correct speed. 20060923 Connecting dev_gt to the timer framework, so that NetBSD/cobalt runs at correct speed. Moving SH4-specific memory mapped registers into its own device (dev_sh4.c). Running with -N now prints "idling" instead of bogus nr of instrs/second (which isn't valid anyway) while idling. 20060924 Algor emulation should now run at correct speed. Adding disassembly support for some MIPS64 revision 2 instructions: ext, dext, dextm, dextu. 20060926 The timer framework now works also when the MIPS wait instruction is used. 20060928 Re-implementing checks for coprocessor availability for MIPS cop0 instructions. (Thanks to Carl van Schaik for noticing the lack of cop0 availability checks.) 20060929 Implementing an instruction combination hack which treats NetBSD/pmax' idle loop as a wait-like instruction. 20060930 The ENTRYHI_R_MASK was missing in (at least) memory_mips_v2p.c, causing TLB lookups to sometimes succeed when they should have failed. (A big thank you to Juli Mallett for noticing the problem.) Adding disassembly support for more MIPS64 revision 2 opcodes (seb, seh, wsbh, jalr.hb, jr.hb, synci, ins, dins, dinsu, dinsm, dsbh, dshd, ror, dror, rorv, drorv, dror32). Also implementing seb, seh, dsbh, dshd, and wsbh. Implementing an instruction combination hack for Linux/pmax' idle loop, similar to the NetBSD/pmax case. 20061001 Changing the NetBSD/sgimips install instructions to extract files from an iso image, instead of downloading them via ftp. 20061002 More-than-31-bit userland addresses in memory_mips_v2p.c were not actually working; applying a fix from Carl van Schaik to enable them to work + making some other updates (adding kuseg support). Fixing hpcmips (vr41xx) timer initialization. Experimenting with O(n)->O(1) reduction in the MIPS TLB lookup loop. Seems to work both for R3000 and non-R3000. 20061003 Continuing a little on SH emulation (adding more control registers; mini-cleanup of memory_sh.c). 20061004 Beginning on a dev_rtc, a clock/timer device for the test machines; also adding a demo, and some documentation. Fixing a bug in SH "mov.w @(disp,pc),Rn" (the result wasn't sign-extended), and adding the addc and ldtlb instructions. 20061005 Contining on SH emulation: virtual to physical address translation, and a skeleton exception mechanism. 20061006 Adding more SH instructions (various loads and stores, rte, negc, muls.w, various privileged register-move instructions). 20061007 More SH instructions: various move instructions, trapa, div0s, float, fdiv, ftrc. Continuing on dev_rtc; removing the rtc demo. 20061008 Adding a dummy Dreamcast PROM module. (Homebrew Dreamcast programs using KOS libs need this.) Adding more SH instructions: "stc vbr,rn", rotl, rotr, fsca, fmul, fadd, various floating-point moves, etc. A 256-byte demo for Dreamcast runs :-) 20061012 Adding the SH "lds Rm,pr" and bsr instructions. 20061013 More SH instructions: "sts fpscr,rn", tas.b, and some more floating point instructions, cmp/str, and more moves. Adding a dummy dev_pvr (Dreamcast graphics controller). 20061014 Generalizing the expression evaluator (used in the built-in debugger) to support parentheses and +-*/%^&|. 20061015 Removing the experimental tlb index hint code in mips_memory_v2p.c, since it didn't really have any effect. 20061017 Minor SH updates; adding the "sts pr,Rn", fcmp/gt, fneg, frchg, and some other instructions. Fixing missing sign- extension in an 8-bit load instruction. 20061019 Adding a simple dev_dreamcast_rtc. Implementing memory-mapped access to the SH ITLB/UTLB arrays. 20061021 Continuing on various SH and Dreamcast things: sh4 timers, debug messages for dev_pvr, fixing some virtual address translation bugs, adding the bsrf instruction. The NetBSD/dreamcast GENERIC_MD kernel now reaches userland :) Adding a dummy dev_dreamcast_asic.c (not really useful yet). Implementing simple support for Store Queues. Beginning on the PVR Tile Accelerator. 20061022 Generalizing the PVR framebuffer to support off-screen drawing, multiple bit-depths, etc. (A small speed penalty, but most likely worth it.) Adding more SH instructions (mulu.w, fcmp/eq, fsub, fmac, fschg, and some more); correcting bugs in "fsca" and "float". 20061024 Adding the SH ftrv (matrix * vector) instruction. Marcus Comstedt's "tatest" example runs :) (wireframe only). Correcting disassembly for SH floating point instructions that use the xd* registers. Adding the SH fsts instruction. In memory_device_dyntrans_access(), only the currently used range is now invalidated, and not the entire device range. 20061025 Adding a dummy AVR32 cpu mode skeleton. 20061026 Various Dreamcast updates; beginning on a Maple bus controller. 20061027 Continuing on the Maple bus. A bogus Controller, Keyboard, and Mouse can now be detected by NetBSD and KOS homebrew programs. Cleaning up the SH4 Timer Management Unit, and beginning on SH4 interrupts. Implementing the Dreamcast SYSASIC. 20061028 Continuing on the SYSASIC. Adding the SH fsqrt instruction. memory_sh.c now actually scans the ITLB. Fixing a bug in dev_sh4.c, related to associative writes into the memory-mapped UTLB array. NetBSD/dreamcast now reaches userland stably, and prints the "Terminal type?" message :-] Implementing enough of the Dreamcast keyboard to make NetBSD accept it for input. Enabling SuperH for stable (non-development) builds. Adding NetBSD/dreamcast to the documentation, although it doesn't support root-on-nfs yet. 20061029 Changing usleep(1) calls in the debugger to to usleep(10000) (according to Brian Foley, this makes GXemul run better on MacOS X). Making the Maple "Controller" do something (enough to barely interact with dcircus.elf). 20061030-31 Some progress on the PVR. More test programs start running (but with strange output). Various other SH4-related updates. 20061102 Various Dreamcast and SH4 updates; more KOS demos run now. 20061104 Adding a skeleton dev_mb8696x.c (the Dreamcast's LAN adapter). 20061105 Continuing on the MB8696x; NetBSD/dreamcast detects it as mbe0.
