++ trunk/HISTORY (local) $Id: HISTORY,v 1.1515 2007/04/14 05:39:46 debug Exp $ 20070324 Adding a "--debug" option to the configure script, to disable optimizations in unstable development builds. Moving out SCSI-specific stuff from diskimage.c into a new diskimage_scsicmd.c. Applying Hĺvard Eidnes' patch for SCSICDROM_READ_DISKINFO and SCSICDROM_READ_TRACKINFO. (Not really tested yet.) Implementing disk image "overlays" (to allow simple roll-back to previous disk state). Adding a 'V' disk flag for this, and updating the man page and misc.html. 20070325 Stability fix to cpu_dyntrans.c, when multiple physical pages share the same initial table entry. (The ppp == NULL check should be physpage_ofs == 0.) Bug found by analysing GXemul against a version patched for Godson. Fixing a second occurance of the same problem (also in cpu_dyntrans.c). Fixing a MAJOR physical page leak in cpu_dyntrans.c; pages weren't _added_ to the set of translated pages, they _replaced_ all previous pages. It's amazing that this bug has been able to live for this long. (Triggered when emulating >128MB RAM.) 20070326 Removing the GDB debugging stub support; it was too hackish and ugly. 20070328 Moving around some native code generation skeleton code. 20070329 The -lm check in the configure script now also checks for sin() in addition to sqrt(). (Thanks to Nigel Horne for noticing that sqrt was not enough on Fedora Core 6.) (Not verified yet.) 20070330 Fixing an indexing bug in dev_sh4.c, found by using gcc version 4.3.0 20070323. 20070331 Some more experimentation with native code generation. 20070404 Attempting to fix some more SH4 SCIF interrupt bugs; rewriting the SH interrupt assertion/deassertion code somewhat. 20070410 Splitting src/file.c into separate files in src/file/. Cleanup: Removing the dummy TS7200, Walnut, PB1000, and Meshcube emulation modes, and dev_epcom and dev_au1x00. Removing the experimental CHIP8/RCA180x code; it wasn't really working much lately, anyway. It was fun while it lasted. Also removing the experimental Transputer CPU support. 20070412 Moving the section about how the dynamic translation system works from intro.html to a separate translation.html file. Minor SH fixes; attempting to get OpenBSD/landisk to run without randomly bugging out, but no success yet. 20070413 SH SCI (serial bit interface) should now work together with a (new) RS5C313 clock device (for Landisk emulation). 20070414 Moving Redhat/MIPS down from supported to experimental, in guestoses.html. Preparing for a new release; doing some regression testing etc. ============== RELEASE 0.4.5 ==============
++ trunk/HISTORY (local) $Id: HISTORY,v 1.1497 2007/03/18 03:41:36 debug Exp $ 20070224 Minor update to the initialization of the ns16550 in machine_walnut.c, to allow that machine type to boot with the new interrupt system (although it is still a dummy machine). Adding a wdc at 0x14000000 to machine_landisk.c, and fixing the SCIF serial interrupts of the SH4 cpu enough to get NetBSD/landisk booting from a disk image :-) Adding a preliminary install instruction skeleton to guestoses.html. 20070306 Adding SH-IPL+G PROM emulation, and also passing the "end" symbol in r5 on bootup, for Landisk emulation. This is enough to get OpenBSD/landisk to install :) Adding a preliminary install instruction skeleton to the documentation. SuperH emulation is still shaky, though :-/ 20070307 Fixed a strangeness in memory_sh.c (read/write was never returned for any page). (Unknown whether this fixes any actual problems, though.) 20070308 dev_ram.c fix: invalidate code translations on writes to RAM, emulated as separate devices. Linux/dreamcast gets further in the boot process than before, but still bugs out in userland. Fixing bugs in the "stc.l gbr,@-rN" and "ldc.l @rN+,gbr" SuperH instructions (they should NOT check the MD bit), allowing the Linux/dreamcast Live CD to reach userland correctly :-) 20070310 Changing the cpu name "Alpha" in src/useremul.c to "21364" to unbreak userland syscall emulation of FreeBSD/Alpha binaries. 20070314 Applying a patch from Michael Yaroslavtsev which fixes the previous Linux lib64 patch to the configure script. 20070315 Adding a (dummy) sun4v machine type, and SPARC T1 cpu type. 20070316 Creating a new directory, src/disk, and moving diskimage.c to it. Separating out bootblock loading stuff from emul.c into new files in src/disk. Adding some more SPARC registers. 20070318 Preparing/testing for a minirelease, 0.4.4.1. ============== RELEASE 0.4.4.1 ==============
