2576 |
|
|
2577 |
|
20060219 Various minor updates. Removing the old MIPS16 skeleton code, |
2578 |
|
because it will need to be rewritten for dyntrans anyway. |
2579 |
|
20060220-22 Removing the non-working dyntrans backend support. |
2580 |
|
Continuing on the 64-bit dyntrans virtual memory generalization. |

20060223 More work on the 64-bit vm generalization. |
2582 |
|
20060225 Beginning on MIPS dyntrans load/store instructions. |
2583 |
|
Minor PPC updates (64-bit load/store, etc). |
2584 |
|
Fixes for the variable-instruction-length framework, some |
2585 |
|
minor AVR updates (a simple Hello World program works!). |
2586 |
|
Beginning on a skeleton for automatically generating documen- |
2587 |
|
tation (for devices etc.). |

2591 |
|
accept the serial console. |
2592 |
|
20060301 Adding more AVR instructions. |
2593 |
|
20060304 Continuing on AVR-related stuff. Beginning on a framework for |
2594 |

2595 |
|
TV" device (just a dummy so far). |
2596 |
|
20060305 Adding more AVR instructions. |
2597 |
|
Adding a dummy epcom serial controller (for TS7200 emulation). |
2598 |
|
20060310 Removing the emul() command from configuration files, so only |
2599 |
|
net() and machine() are supported. |
2600 |
|
Minor progress on the MIPS dyntrans rewrite. |
2601 |
|
20060311 Continuing on the MIPS dyntrans rewrite (adding more |
2602 |
|
instructions, etc). |
2603 |
|
20060315 Adding more instructions (sllv, srav, srlv, bgtz[l], blez[l], |
2604 |
|
beql, bnel, slti[u], various loads and stores). |
2605 |
|
20060316 Removing the ALWAYS_SIGNEXTEND_32 option, since it was rarely |
2606 |
|
used. |
2607 |
|
Adding more MIPS dyntrans instructions, and fixing bugs. |
2608 |
|
20060318 Implementing fast loads/stores for MIPS dyntrans (big/little |
2609 |
|
endian, 32-bit and 64-bit modes). |
2610 |
|
20060320 Making MIPS dyntrans the default configure option; use |
2611 |
|
"--enable-oldmips" to use the old bintrans system. |
2612 |
|
Adding MIPS dyntrans dmult[u]; minor updates. |
2613 |

2614 |
|
Adding a simple skeleton for demangling C++ "_ZN" symbols. |
2615 |
|
20060323 Moving src/debugger.c into a new directory (src/debugger/). |
2616 |
|
20060324 Fixing the hack used to load PPC ELFs (useful for relocated |
2617 |
|
Linux/ppc kernels), and adding a dummy G3 machine mode. |
2618 |
|
20060325-26 Beginning to experiment with GDB remote serial protocol |
2619 |
|
connections; adding a -G command line option for selecting |
2620 |
|
which TCP port to listen to. |
2621 |
|
20060330 Beginning a major cleanup to replace things like "0x%016llx" |
2622 |
|
with more correct "0x%016"PRIx64, etc. |
2623 |
|
Continuing on the GDB remote serial protocol support. |
2624 |
|
20060331 More cleanup, and some minor GDB remote progress. |
2625 |
|
20060402 Adding a hack to the configure script, to allow compilation |
2626 |
|
on systems that lack PRIx64 etc. |
2627 |
|
20060406 Removing the temporary FreeBSD/arm hack in dev_ns16550.c and |
2628 |
|
replacing it with a better fix from Olivier Houchard. |
2629 |
|
20060407 A remote debugger (gdb or ddd) can now start and stop the |
2630 |
|
emulator using the GDB remote serial protocol, and registers |
2631 |
|
and memory can be read. MIPS only for now. |
2632 |
|
20060408 More GDB progress: single-stepping also works, and also adding |
2633 |
|
support for ARM, PowerPC, and Alpha targets. |
2634 |
|
Continuing on the delay-slot-across-page-boundary issue. |
2635 |
|
20060412 Minor update: beginning to add support for the SPARC target |
2636 |
|
to the remote GDB functionality. |
2637 |
|
20060414 Various MIPS updates: adding more instructions for dyntrans |
2638 |
|
(eret, add), and making some exceptions work. Fixing a bug |
2639 |
|
in dmult[u]. |
2640 |
|
Implementing the first SPARC instructions (sethi, or). |
2641 |
|
20060415 Adding "magic trap" instructions so that PROM calls can be |
2642 |
|
software emulated in MIPS dyntrans. |
2643 |
|
Adding more MIPS dyntrans instructions (ddiv, dadd) and |
2644 |
|
fixing another bug in dmult. |
2645 |
|
20060416 More MIPS dyntrans progress: adding [d]addi, movn, movz, dsllv, |
2646 |
|
rfi, an ugly hack for supporting R2000/R3000 style faked caches, |
2647 |
|
preliminary interrupt support, and various other updates and |
2648 |
|
bugfixes. |
2649 |
|
20060417 Adding more SPARC instructions (add, sub, sll[x], sra[x], |
2650 |
|
srl[x]), and useful SPARC header definitions. |
2651 |
|
Adding the first (trivial) x86/AMD64 dyntrans instructions (nop, |
2652 |
|
cli/sti, stc/clc, std/cld, simple mov, inc ax). Various other |
2653 |
|
x86 updates related to variable instruction length stuff. |
2654 |
|
Adding unaligned loads/stores to the MIPS dyntrans mode (but |
2655 |
|
still using the pre-dyntrans (slow) imlementation). |
2656 |
|
20060419 Fixing a MIPS dyntrans exception-in-delay-slot bug. |
2657 |
|
Removing the old "show opcode statistics" functionality, since |
2658 |
|
it wasn't really useful and isn't implemented for dyntrans. |
2659 |
|
Single-stepping (or running with instruction trace) now looks |
2660 |
|
ok with dyntrans with delay-slot architectures. |
2661 |
|
20060420 Minor hacks (removing the -B command line option when compiled |
2662 |
|
for non-bintrans, and some other very minor updates). |
2663 |
|
Adding (slow) MIPS dyntrans load-linked/store-conditional. |
2664 |
|
20060422 Applying fixes for bugs discovered by Nils Weller's nwcc |
2665 |
|
(static DEC memmap => now per machine, and adding an extern |
2666 |
|
keyword in cpu_arm_instr.c). |
2667 |
|
Finally found one of the MIPS dyntrans bugs that I've been |
2668 |
|
looking for (copy/paste spelling error BIG vs LITTLE endian in |
2669 |
|
cpu_mips_instr_loadstore.c for 16-bit fast stores). |
2670 |
|
FINALLY found the major MIPS dyntrans bug: slti vs sltiu |
2671 |
|
signed/unsigned code in cpu_mips_instr.c. :-) |
2672 |
|
Adding more MIPS dyntrans instructions (lwc1, swc1, bgezal[l], |
2673 |
|
ctc1, tlt[u], tge[u], tne, beginning on rdhwr). |
2674 |
|
NetBSD/hpcmips can now reach userland when using dyntrans :-) |
2675 |
|
Adding some more x86 dyntrans instructions. |
2676 |
|
Finally removed the old Alpha-specific virtual memory code, |
2677 |
|
and replaced it with the generic 64-bit version. |
2678 |
|
Beginning to add disassembly support for SPECIAL3 MIPS opcodes. |
2679 |
|
20060423 Continuing on the delay-slot-across-page-boundary issue; |
2680 |
|
adding an end_of_page2 ic slot (like I had planned before, but |
2681 |
|
had removed for some reason). |
2682 |
|
Adding a quick-and-dirty fallback to legacy coprocessor 1 |
2683 |
|
code (i.e. skipping dyntrans implementation for now). |
2684 |
|
NetBSD/hpcmips and NetBSD/pmax (when running on an emulated |
2685 |
|
R4400) can now be installed and run. :-) (Many bugs left |
2686 |
|
to fix, though.) |
2687 |
|
Adding more MIPS dyntrans instructions: madd[u], msub[u]. |
2688 |
|
Cleaning up the SPECIAL2 vs R5900/TX79/C790 "MMI" opcode |
2689 |
|
maps somewhat (disassembly and dyntrans instruction decoding). |
2690 |
|
20060424 Adding an isa_revision field to mips_cpu_types.h, and making |
2691 |
|
sure that SPECIAL3 opcodes cause Reserved Instruction |
2692 |
|
exceptions on MIPS32/64 revisions lower than 2. |
2693 |
|
Adding the SPARC 'ba', 'call', 'jmpl/retl', 'and', and 'xor' |
2694 |
|
instructions. |
2695 |
|
20060425 Removing the -m command line option ("run at most x |
2696 |
|
instructions") and -T ("single_step_on_bad_addr"), because |
2697 |
|
they never worked correctly with dyntrans anyway. |
2698 |
|
Freshening up the man page. |
2699 |
|
20060428 Adding more MIPS dyntrans instructions: bltzal[l], idle. |
2700 |
|
Enabling MIPS dyntrans compare interrupts. |
2701 |
|
20060429 FINALLY found the weird dyntrans bug, causing NetBSD etc. to |
2702 |
|
behave strangely: some floating point code (conditional |
2703 |
|
coprocessor branches) could not be reused from the old |
2704 |
|
non-dyntrans code. The "quick-and-dirty fallback" only appeared |
2705 |
|
to work. Fixing by implementing bc1* for MIPS dyntrans. |
2706 |
|
More MIPS instructions: [d]sub, sdc1, ldc1, dmtc1, dmfc1, cfc0. |
2707 |
|
Freshening up MIPS floating point disassembly appearance. |
2708 |
|
20060430 Continuing on C790/R5900/TX79 disassembly; implementing 128-bit |
2709 |
|
"por" and "pextlw". |
2710 |
|
20060504 Disabling -u (userland emulation) unless compiled as unstable |
2711 |
|
development version. |
2712 |
|
Beginning on freshening up the testmachine include files, |
2713 |
|
to make it easier to reuse those files (placing them in |
2714 |
|
src/include/testmachine/), and beginning on a set of "demos" |
2715 |
|
or "tutorials" for the testmachine functionality. |
2716 |
|
Minor updates to the MIPS GDB remote protocol stub. |
2717 |
|
Refreshing doc/experiments.html and gdb_remote.html. |
2718 |
|
Enabling Alpha emulation in the stable release configuration, |
2719 |
|
even though no guest OSes for Alpha can run yet. |
2720 |
|
20060505 Adding a generic 'settings' object, which will contain |
2721 |
|
references to settable variables (which will later be possible |
2722 |
|
to access using the debugger). |
2723 |
|
20060506 Updating dev_disk and corresponding demo/documentation (and |
2724 |
|
switching from SCSI to IDE disk types, so it actually works |
2725 |
|
with current test machines :-). |
2726 |
|
20060510 Adding a -D_LARGEFILE_SOURCE hack for 64-bit Linux hosts, |
2727 |
|
so that fseeko() doesn't give a warning. |
2728 |
|
Updating the section about how dyntrans works (the "runnable |
2729 |
|
IR") in doc/intro.html. |
2730 |
|
Instruction updates (some x64=1 checks, some more R5900 |
2731 |
|
dyntrans stuff: better mul/mult separation from MIPS32/64, |
2732 |
|
adding ei and di). |
2733 |
|
Updating MIPS cpuregs.h to a newer one (from NetBSD). |
2734 |
|
Adding more MIPS dyntrans instructions: deret, ehb. |
2735 |
|
20060514 Adding disassembly and beginning implementation of SPARC wr |
2736 |
|
and wrpr instructions. |
2737 |
|
20060515 Adding a SUN SPARC machine mode, with dummy SS20 and Ultra1 |
2738 |
|
machines. Adding the 32-bit "rd psr" instruction. |
2739 |
|
20060517 Disassembly support for the general SPARC rd instruction. |
2740 |
|
Partial implementation of the cmp (subcc) instruction. |
2741 |
|
Some other minor updates (making sure that R5900 processors |
2742 |
|
start up with the EIE bit enabled, otherwise Linux/playstation2 |
2743 |
|
receives no interrupts). |
2744 |
|
20060519 Minor MIPS updates/cleanups. |
2745 |
|
20060521 Moving the MeshCube machine into evbmips; this seems to work |
2746 |
|
reasonably well with a snapshot of a NetBSD MeshCube kernel. |
2747 |
|
Cleanup/fix of MIPS config0 register initialization. |
2748 |
|
20060529 Minor MIPS fixes, including a sign-extension fix to the |
2749 |
|
unaligned load/store code, which makes NetBSD/pmax on R3000 |
2750 |
|
work better with dyntrans. (Ultrix and Linux/DECstation still |
2751 |
|
don't work, though.) |
2752 |
|
20060530 Minor updates to the Alpha machine mode: adding an AlphaBook |
2753 |
|
mode, an LCA bus (forwarding accesses to an ISA bus), etc. |
2754 |
|
20060531 Applying a bugfix for the MIPS dyntrans sc[d] instruction from |
2755 |
|
Ondrej Palkovsky. (Many thanks.) |
2756 |
|
20060601 Minifix to allow ARM immediate msr instruction to not give |
2757 |
|
an error for some valid values. |
2758 |
|
More Alpha updates. |
2759 |
|
20060602 Some minor Alpha updates. |
2760 |
|
20060603 Adding the Alpha cmpbge instruction. NetBSD/alpha prints its |
2761 |
|
first boot messages :-) on an emulated Alphabook 1. |
2762 |
|
20060612 Minor updates; adding a dev_ether.h include file for the |
2763 |
|
testmachine ether device. Continuing the hunt for the dyntrans |
2764 |
|
bug which makes Linux and Ultrix on DECstation behave |
2765 |
|
strangely... FINALLY found it! It seems to be related to |
2766 |
|
invalidation of the translation cache, on tlbw{r,i}. There |
2767 |
|
also seems to be some remaining interrupt-related problems. |
2768 |
|
20060614 Correcting the implementation of ldc1/sdc1 for MIPS dyntrans |
2769 |
|
(so that it uses 16 32-bit registers if the FR bit in the |
2770 |
|
status register is not set). |
2771 |
|
20060616 REMOVING BINTRANS COMPLETELY! |
2772 |
|
Removing the old MIPS interpretation mode. |
2773 |
|
Removing the MFHILO_DELAY and instruction delay stuff, because |
2774 |
|
they wouldn't work with dyntrans anyway. |
2775 |
|
20060617 Some documentation updates (adding "NetBSD-archive" to some |
2776 |
|
URLs, and new Debian/DECstation installation screenshots). |
2777 |
|
Removing the "tracenull" and "enable-caches" configure options. |
2778 |
|
Improving MIPS dyntrans performance somewhat (only invalidate |
2779 |
|
translations if necessary, on writes to the entryhi register, |
2780 |
|
instead of doing it for all cop0 writes). |
2781 |
|
20060618 More cleanup after the removal of the old MIPS emulation. |
2782 |
|
Trying to fix the MIPS dyntrans performance bugs/bottlenecks; |
2783 |
|
only semi-successful so far (for R3000). |
2784 |
|
20060620 Minor update to allow clean compilation again on Tru64/Alpha. |
2785 |
|
20060622 MIPS cleanup and fixes (removing the pc_last stuff, which |
2786 |
|
doesn't make sense with dyntrans anyway, and fixing a cross- |
2787 |
|
page-delay-slot-with-exception case in end_of_page). |
2788 |
|
Removing the old max_random_cycles_per_chunk stuff, and the |
2789 |
|
concept of cycles vs instructions for MIPS emulation. |
2790 |
|
FINALLY found and fixed the bug which caused NetBSD/pmax |
2791 |
|
clocks to behave strangely (it was a load to the zero register, |
2792 |
|
which was treated as a NOP; now it is treated as a load to a |
2793 |
|
dummy scratch register). |
2794 |
|
20060623 Increasing the dyntrans chunk size back to |
2795 |
|
N_SAFE_DYNTRANS_LIMIT, instead of N_SAFE_DYNTRANS_LIMIT/2. |
2796 |
|
Preparing for a quick release, even though there are known |
2797 |
|
bugs, and performance for non-R3000 MIPS emulation is very |
2798 |
|
poor. :-/ |
2799 |
|
Reverting to half the dyntrans chunk size again, because |
2800 |
|
NetBSD/cats seemed less stable with full size chunks. :( |
2801 |
|
NetBSD/sgimips 3.0 can now run :-) (With release 0.3.8, only |
2802 |
|
NetBSD/sgimips 2.1 worked, not 3.0.) |
2803 |
|
|
2804 |
|
============== RELEASE 0.4.0 ============== |
2805 |
|
|
2806 |
|
20060624 Replacing the error-prone machine type initialization stuff |
2807 |
|
with something more reasonable. |
2808 |
|
Finally removing the old "cpu_run" kludge; moving around stuff |
2809 |
|
in machine.c and emul.c to better suit the dyntrans system. |
2810 |
|
Various minor dyntrans cleanups (renaming translate_address to |
2811 |
|
translate_v2p, and experimenting with template physpages). |
2812 |
|
20060625 Removing the speed hack which separated the vph entries into |
2813 |
|
two halves (code vs data); things seem a lot more stable now. |
2814 |
|
Minor performance hack: R2000/R3000 cache isolation now only |
2815 |
|
clears address translations when going into isolation, not |
2816 |
|
when going out of it. |
2817 |
|
Fixing the MIPS interrupt problems by letting mtc0 immediately |
2818 |
|
cause interrupts. |
2819 |
|
|
2820 |
|
============== RELEASE 0.4.0.1 ============== |
2821 |
|
|
2822 |
|
20060626 Continuing on SPARC emulation (beginning on the 'save' |
2823 |
|
instruction, register windows, etc). |
2824 |
|
20060629 Planning statistics gathering (new -s command line option), |
2825 |
|
and renaming speed_tricks to allow_instruction_combinations. |
2826 |
|
20060630 Some minor manual page updates. |
2827 |
|
Various cleanups. |
2828 |
|
Implementing the -s command line option. |
2829 |
|
20060701 FINALLY found the bug which prevented Linux and Ultrix from |
2830 |
|
running without the ugly hack in the R2000/R3000 cache isol |
2831 |
|
code; it was the phystranslation hint array which was buggy. |
2832 |
|
Removing the phystranslation hint code completely, for now. |
2833 |
|
20060702 Minor dyntrans cleanups; invalidation of physpages now only |
2834 |
|
invalidate those parts of a page that have actually been |
2835 |
|
translated. (32 parts per page.) |
2836 |
|
Some MIPS non-R3000 speed fixes. |
2837 |
|
Experimenting with MIPS instruction combination for some |
2838 |
|
addiu+bne+sw loops, and sw+sw+sw. |
2839 |
|
Adding support (again) for larger-than-4KB pages in MIPS tlbw*. |
2840 |
|
Continuing on SPARC emulation: adding load/store instructions. |
2841 |
|
20060704 Fixing a virtual vs physical page shift bug in the new tlbw* |
2842 |
|
implementation. Problem noticed by Jakub Jermar. (Many thanks.) |
2843 |
|
Moving rfe and eret to cpu_mips_instr.c, since that is the |
2844 |
|
only place that uses them nowadays. |
2845 |
|
20060705 Removing the BSD license from the "testmachine" include files, |
2846 |
|
placing them in the public domain instead; this enables the |
2847 |
|
testmachine stuff to be used from projects which are |
2848 |
|
incompatible with the BSD license for some reason. |
2849 |
|
20060707 Adding instruction combinations for the R2000/R3000 L1 |
2850 |
|
I-cache invalidation code used by NetBSD/pmax 3.0, lui+addiu, |
2851 |
|
various branches followed by addiu or nop, and jr ra followed |
2852 |
|
by addiu. The time it takes to perform a full NetBSD/pmax R3000 |
2853 |
|
install on the laptop has dropped from 573 seconds to 539. :-) |
2854 |
|
20060708 Adding a framebuffer controller device (dev_fbctrl), which so |
2855 |
|
far can be used to change the fb resolution during runtime, but |
2856 |
|
in the future will also be useful for accelerated block fill/ |
2857 |
|
copy, and possibly also simplified character output. |
2858 |
|
Adding an instruction combination for NetBSD/pmax' strlen. |
2859 |
|
20060709 Minor fixes: reading raw files in src/file.c wasn't memblock |
2860 |
|
aligned, removing buggy multi_sw MIPS instruction combination, |
2861 |
|
etc. |
2862 |
|
20060711 Adding a machine_qemu.c, which contains a "qemu_mips" machine. |
2863 |
|
(It mimics QEMU's MIPS machine mode, so that a test kernel |
2864 |
|
made for QEMU_MIPS also can run in GXemul... at least to some |
2865 |
|
extent.) Adding a short section about how to run this mode to |
2866 |
|
doc/guestoses.html. |
2867 |
|
20060714 Misc. minor code cleanups. |
2868 |
|
20060715 Applying a patch which adds getchar() to promemul/yamon.c |
2869 |
|
(from Oleksandr Tymoshenko). |
2870 |
|
Adding yamon.h from NetBSD, and rewriting yamon.c to use it |
2871 |
|
(instead of ugly hardcoded numbers) + some cleanup. |
2872 |
|
20060716 Found and fixed the bug which broke single-stepping of 64-bit |
2873 |
|
programs between 0.4.0 and 0.4.0.1 (caused by too quick |
2874 |
|
refactoring and no testing). Hopefully this fix will not |
2875 |
|
break too many other things. |
2876 |
|
20060718 Continuing on the 8253 PIT; it now works with Linux/QEMU_MIPS. |
2877 |
|
Re-adding the sw+sw+sw instr comb (the problem was that I had |
2878 |
|
ignored endian issues); however, it doesn't seem to give any |
2879 |
|
big performance gain. |
2880 |
|
20060720 Adding a dummy Transputer mode (T414, T800 etc) skeleton (only |
2881 |
|
the 'j' and 'ldc' instructions are implemented so far). :-} |
2882 |
|
20060721 Adding gtreg.h from NetBSD, updating dev_gt.c to use it, plus |
2883 |
|
misc. other updates to get Linux 2.6 for evbmips/malta working |
2884 |
|
(thanks to Alec Voropay for the details). |
2885 |
|
FINALLY found and fixed the bug which made tlbw* for non-R3000 |
2886 |
|
buggy; it was a reference count problem in the dyntrans core. |
2887 |
|
20060722 Testing stuff; things seem stable enough for a new release. |
2888 |
|
|
2889 |
|
============== RELEASE 0.4.1 ============== |
2890 |
|
|
2891 |
|
20060723 More Transputer instructions (pfix, nfix, opr, mint, ldl, ldlp, |
2892 |
|
eqc, rev, ajw, stl, stlf, sthf, sub, ldnl, ldnlp, ldpi, move, |
2893 |
|
wcnt, add, bcnt). |
2894 |
|
Adding more SPARC instructions (andcc, addcc, bl, rdpr). |
2895 |
|
Progress on the igsfb framebuffer used by NetBSD/netwinder. |
2896 |
|
Enabling 8-bit fills in dev_fb. |
2897 |
|
NetBSD/netwinder 3.0.1 can now run from a disk image :-) |
2898 |
|
20060724 Cleanup/performance fix for 64-bit virtual translation table |
2899 |
|
updates (by removing the "timestamp" stuff). A full NetBSD/pmax |
2900 |
|
3.0.1 install for R4400 has dropped from 667 seconds to 584 :) |
2901 |
|
Fixing the igsfb "almost vga" color (it is 24-bit, not 18-bit). |
2902 |
|
Adding some MIPS instruction combinations (3*lw, and 3*addu). |
2903 |
|
The 8048 keyboard now turns off interrupt enable between the |
2904 |
|
KBR_ACK and the KBR_RSTDONE, to work better with Linux 2.6. |
2905 |
|
Not causing PPC DEC interrupts if PPC_NO_DEC is set for a |
2906 |
|
specific CPU; NetBSD/bebox gets slightly further than before. |
2907 |
|
Adding some more SPARC instructions: branches, udiv. |
2908 |
|
20060725 Refreshing dev_pckbc.c a little. |
2909 |
|
Cleanups for the SH emulation mode, and adding the first |
2910 |
|
"compact" (16-bit) instructions: various simple movs, nop, |
2911 |
|
shll, stc, or, ldc. |
2912 |
|
20060726 Adding dummy "pcn" (AMD PCnet NIC) PCI glue. |
2913 |
|
20060727 Various cleanups; removing stuff from cpu.h, such as |
2914 |
|
running_translated (not really meaningful anymore), and |
2915 |
|
page flags (breaking into the debugger clears all translations |
2916 |
|
anyway). |
2917 |
|
Minor MIPS instruction combination updates. |
2918 |
|
20060807 Expanding the 3*sw and 3*lw MIPS instruction combinations to |
2919 |
|
work with 2* and 4* too, resulting in a minor performance gain. |
2920 |
|
Implementing a usleep hack for the RM52xx/MIPS32/MIPS64 "wait" |
2921 |
|
instruction (when emulating 1 cpu). |
2922 |
|
20060808 Experimenting with some more MIPS instruction combinations. |
2923 |
|
Implementing support for showing a (hardcoded 12x22) text |
2924 |
|
cursor in igsfb. |
2925 |
|
20060809 Simplifying the NetBSD/evbmips (Malta) install instructions |
2926 |
|
somewhat (by using a NetBSD/pmax ramdisk install kernel). |
2927 |
|
20060812 Experimenting more with the MIPS 'wait' instruction. |
2928 |
|
PCI configuration register writes can now be handled, which |
2929 |
|
allow PCI IDE controllers to work with NetBSD/Malta 3.0.1 and |
2930 |
|
NetBSD/cobalt 3.0.1. (Previously only NetBSD 2.1 worked.) |
2931 |
|
20060813 Updating dev_gt.c based on numbers from Alec Voropay, to enable |
2932 |
|
Linux 2.6 to use PCI on Malta. |
2933 |
|
Continuing on Algor interrupt stuff. |
2934 |
|
20060814 Adding support for routing ISA interrupts to two different |
2935 |
|
interrupts, making it possible to run NetBSD/algor :-) |
2936 |
|
20060814-15 Testing for the release. |
2937 |
