============== RELEASE 0.4.0.1 ============== |
============== 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. |
