++ trunk/HISTORY (local) $Id: HISTORY,v 1.1298 2006/07/22 11:27:46 debug Exp $ 20060626 Continuing on SPARC emulation (beginning on the 'save' instruction, register windows, etc). 20060629 Planning statistics gathering (new -s command line option), and renaming speed_tricks to allow_instruction_combinations. 20060630 Some minor manual page updates. Various cleanups. Implementing the -s command line option. 20060701 FINALLY found the bug which prevented Linux and Ultrix from running without the ugly hack in the R2000/R3000 cache isol code; it was the phystranslation hint array which was buggy. Removing the phystranslation hint code completely, for now. 20060702 Minor dyntrans cleanups; invalidation of physpages now only invalidate those parts of a page that have actually been translated. (32 parts per page.) Some MIPS non-R3000 speed fixes. Experimenting with MIPS instruction combination for some addiu+bne+sw loops, and sw+sw+sw. Adding support (again) for larger-than-4KB pages in MIPS tlbw*. Continuing on SPARC emulation: adding load/store instructions. 20060704 Fixing a virtual vs physical page shift bug in the new tlbw* implementation. Problem noticed by Jakub Jermar. (Many thanks.) Moving rfe and eret to cpu_mips_instr.c, since that is the only place that uses them nowadays. 20060705 Removing the BSD license from the "testmachine" include files, placing them in the public domain instead; this enables the testmachine stuff to be used from projects which are incompatible with the BSD license for some reason. 20060707 Adding instruction combinations for the R2000/R3000 L1 I-cache invalidation code used by NetBSD/pmax 3.0, lui+addiu, various branches followed by addiu or nop, and jr ra followed by addiu. The time it takes to perform a full NetBSD/pmax R3000 install on the laptop has dropped from 573 seconds to 539. :-) 20060708 Adding a framebuffer controller device (dev_fbctrl), which so far can be used to change the fb resolution during runtime, but in the future will also be useful for accelerated block fill/ copy, and possibly also simplified character output. Adding an instruction combination for NetBSD/pmax' strlen. 20060709 Minor fixes: reading raw files in src/file.c wasn't memblock aligned, removing buggy multi_sw MIPS instruction combination, etc. 20060711 Adding a machine_qemu.c, which contains a "qemu_mips" machine. (It mimics QEMU's MIPS machine mode, so that a test kernel made for QEMU_MIPS also can run in GXemul... at least to some extent.) Adding a short section about how to run this mode to doc/guestoses.html. 20060714 Misc. minor code cleanups. 20060715 Applying a patch which adds getchar() to promemul/yamon.c (from Oleksandr Tymoshenko). Adding yamon.h from NetBSD, and rewriting yamon.c to use it (instead of ugly hardcoded numbers) + some cleanup. 20060716 Found and fixed the bug which broke single-stepping of 64-bit programs between 0.4.0 and 0.4.0.1 (caused by too quick refactoring and no testing). Hopefully this fix will not break too many other things. 20060718 Continuing on the 8253 PIT; it now works with Linux/QEMU_MIPS. Re-adding the sw+sw+sw instr comb (the problem was that I had ignored endian issues); however, it doesn't seem to give any big performance gain. 20060720 Adding a dummy Transputer mode (T414, T800 etc) skeleton (only the 'j' and 'ldc' instructions are implemented so far). :-} 20060721 Adding gtreg.h from NetBSD, updating dev_gt.c to use it, plus misc. other updates to get Linux 2.6 for evbmips/malta working (thanks to Alec Voropay for the details). FINALLY found and fixed the bug which made tlbw* for non-R3000 buggy; it was a reference count problem in the dyntrans core. 20060722 Testing stuff; things seem stable enough for a new release. ============== RELEASE 0.4.1 ==============
