++ trunk/HISTORY (local) $Id: HISTORY,v 1.1004 2005/10/27 14:01:10 debug Exp $ 20051011 Passing -A as the default boot arg for CATS (works fine with OpenBSD/cats). 20051012 Fixing the VGA cursor offset bug, and speeding up framebuffer redraws if character cells contain the same thing as during the last redraw. 20051013 Adding a slow strd ARM instruction hack. 20051017 Minor updates: Adding a dummy i80321 Verde controller (for XScale emulation), fixing the disassembly of the ARM "ldrd" instruction, adding "support" for less-than-4KB pages for ARM (by not adding them to translation tables). 20051020 Continuing on some HPCarm stuff. A NetBSD/hpcarm kernel prints some boot messages on an emulated Jornada 720. Making dev_ram work better with dyntrans (speeds up some things quite a bit). 20051021 Automatically generating some of the most common ARM load/store multiple instructions. 20051022 Better statistics gathering for the ARM load/store multiple. Various other dyntrans and device updates. 20051023 Various minor updates. 20051024 Continuing; minor device and dyntrans fine-tuning. Adding the first "reasonable" instruction combination hacks for ARM (the cores of NetBSD/cats' memset and memcpy). 20051025 Fixing a dyntrans-related bug in dev_vga. Also changing the dyntrans low/high access notification to only be updated on writes, not reads. Hopefully it will be enough. (dev_vga in charcell mode now seems to work correctly with both reads and writes.) Experimenting with gathering dyntrans statistics (which parts of emulated RAM that are actually executed), and adding instruction combination hacks for cache cleaning and a part of NetBSD's scanc() function. 20051026 Adding a bitmap for ARM emulation which indicates if a page is (specifically) user accessible; loads and stores with the t- flag set can now use the translation arrays, which results in a measurable speedup. 20051027 Dyntrans updates; adding an extra bitmap array for 32-bit emulation modes, speeding up the check whether a physical page has any code translations or not (O(n) -> O(1)). Doing a similar reduction of O(n) to O(1) by avoiding the scan through the translation entries on a translation update (32-bit mode only). Various other minor hacks. 20051029 Quick release, without any testing at all. ============== RELEASE 0.3.6.2 ==============
++ trunk/HISTORY (local) $Id: HISTORY,v 1.707 2005/04/27 16:37:33 debug Exp $ 20050408 Some minor updates to the wdc. Linux now doesn't complain anymore if a disk is non-present. 20050409 Various minor fixes (a bintrans bug, and some other things). The wdc seems to work with Playstation2 emulation, but there is a _long_ annoying delay when disks are detected. Fixing a really important bintrans bug (when devices and RAM are mixed within 4KB pages), which was triggered with NetBSD/playstation2 kernels. 20050410 Adding a dummy dev_ps2_ether (just so that NetBSD doesn't complain as much during bootup). Symbols starting with '$' are now ignored. Renaming dev_ps2_ohci.c to dev_ohci.c, etc. 20050411 Moving the bintrans-cache-isolation check from cpu_mips.c to cpu_mips_coproc.c. (I thought this would give a speedup, but it's not noticable.) Better playstation2 sbus interrupt code. Skip ahead many ticks if the count register is read manually. (This increases the speed of delay-loops that simply read the count register.) 20050412 Updates to the playstation2 timer/interrupt code. Some other minor updates. 20050413 NetBSD/cobalt runs from a disk image :-) including userland; updating the documentation on how to install NetBSD/cobalt using NetBSD/pmax (!). Some minor bintrans updates (no real speed improvement) and other minor updates (playstation2 now uses the -o options). 20050414 Adding a dummy x86 (and AMD64) mode. 20050415 Adding some (32-bit and 16-bit) x86 instructions. Adding some initial support for non-SCSI, non-IDE floppy images. (The x86 mode can boot from these, more or less.) Moving the devices/ and include/ directories to src/devices/ and src/include/, respectively. 20050416 Continuing on the x86 stuff. (Adding pc_bios.c and some simple support for software interrupts in 16-bit mode.) 20050417 Ripping out most of the x86 instruction decoding stuff, trying to rewrite it in a cleaner way. Disabling some of the least working CPU families in the configure script (sparc, x86, alpha, hppa), so that they are not enabled by default. 20050418 Trying to fix the bug which caused problems when turning on and off bintrans interactively, by flushing the bintrans cache whenever bintrans is manually (re)enabled. 20050419 Adding the 'lswi' ppc instruction. Minor updates to the x86 instruction decoding. 20050420 Renaming x86 register name indices from R_xx to X86_R_xx (this makes building on Tru64 nicer). 20050422 Adding a check for duplicate MIPS TLB entries on tlbwr/tlbwi. 20050427 Adding screenshots to guestoses.html. Some minor fixes and testing for the next release. ============== RELEASE 0.3.2 ==============
