Adding a dummy mvme88k machine mode. 20070502 Re-adding MIPS load/store alignment exceptions. 20070503 Implementing more of the M88K disassembly code. 20070504 Adding disassembly of some more M88K load/store instructions. Implementing some relatively simple M88K instructions (br.n, xor[.u] imm, and[.u] imm). 20070505 Implementing M88K three-register and, or, xor, and jmp[.n], bsr[.n] including function call trace stuff. Applying a patch from Bruce M. Simpson which implements the SYSCON_BOARD_CPU_CLOCK_FREQ_ID object of the syscon call in the yamon PROM emulation. 20070506 Implementing M88K bb0[.n] and bb1[.n], and skeletons for ldcr and stcr (although no control regs are implemented yet). 20070509 Found and fixed the bug which caused Linux for QEMU_MIPS to stop working in 0.4.5.1: It was a faulty change to the MIPS 'sc' and 'scd' instructions I made while going through gcc -W warnings on 20070428. 20070510 Updating the Linux/QEMU_MIPS section in guestoses.html to use mips-test-0.2.tar.gz instead of 0.1. A big thank you to Miod Vallat for sending me M88K manuals. Implementing more M88K instructions (addu, subu, div[u], mulu, ext[u], clr, set, cmp). 20070511 Fixing bugs in the M88K "and" and "and.u" instructions (found by comparing against the manual). Implementing more M88K instructions (mask[.u], mak, bcnd (auto- generated)) and some more control register details. Cleanup: Removing the experimental AVR emulation mode and corresponding devices; AVR emulation wasn't really meaningful. Implementing autogeneration of most M88K loads/stores. The rectangle drawing demo (with -O0) for M88K runs :-) Beginning on M88K exception handling. More M88K instructions: tb0, tb1, rte, sub, jsr[.n]. Adding some skeleton MVME PROM ("BUG") emulation. 20070512 Fixing a bug in the M88K cmp instruction. Adding the M88K lda (scaled register) instruction. Fixing bugs in 64-bit (32-bit pairs) M88K loads/stores. Removing the unused tick_hz stuff from the machine struct. Implementing the M88K xmem instruction. OpenBSD/mvme88k gets far enough to display the Copyright banner :-) Implementing subu.co (guess), addu.co, addu.ci, ff0, and ff1. Adding a dev_mvme187, for MVME187-specific devices/registers. OpenBSD/mvme88k prints more boot messages. :) 20070515 Continuing on MVME187 emulation (adding more devices, beginning on the CMMUs, etc). Adding the M88K and.c, xor.c, and or.c instructions, and making sure that mul, div, etc cause exceptions if executed when SFD1 is disabled. 20070517 Continuing on M88K and MVME187 emulation in general; moving the CMMU registers to the CPU struct, separating dev_pcc2 from dev_mvme187, and beginning on memory_m88k.c (BATC and PATC). Fixing a bug in 64-bit (32-bit pairs) M88K fast stores. Implementing the clock part of dev_mk48txx. Implementing the M88K fstcr and xcr instructions. Implementing m88k_cpu_tlbdump(). Beginning on the implementation of a separate address space for M88K .usr loads/stores. 20070520 Removing the non-working (skeleton) Sandpoint, SonyNEWS, SHARK Dnard, and Zaurus machine modes. Experimenting with dyntrans to_be_translated read-ahead. It seems to give a very small performance increase for MIPS emulation, but a large performance degradation for SuperH. Hm. 20070522 Disabling correct SuperH ITLB emulation; it does not seem to be necessary in order to let SH4 guest OSes run, and it slows down userspace code. Implementing "samepage" branches for SuperH emulation, and some other minor speed hacks. 20070525 Continuing on M88K memory-related stuff: exceptions, memory transaction register contents, etc. Implementing the M88K subu.ci instruction. Removing the non-working (skeleton) Iyonix machine mode. OpenBSD/mvme88k reaches userland :-), starts executing /sbin/init's instructions, and issues a few syscalls, before crashing. 20070526 Fixing bugs in dev_mk48txx, so that OpenBSD/mvme88k detects the correct time-of-day. Implementing a generic IRQ controller for the test machines (dev_irqc), similar to a proposed patch from Petr Stepan. Experimenting some more with translation read-ahead. Adding an "expect" script for automated OpenBSD/landisk install regression/performance tests. 20070527 Adding a dummy mmEye (SH3) machine mode skeleton. FINALLY found the strange M88K bug I have been hunting: I had not emulated the SNIP value for exceptions occurring in branch delay slots correctly. Implementing correct exceptions for 64-bit M88K loads/stores. Address to symbol lookups are now disabled when M88K is running in usermode (because usermode addresses don't have anything to do with supervisor addresses). 20070531 Removing the mmEye machine mode skeleton. 20070604 Some minor code cleanup. 20070605 Moving src/useremul.c into a subdir (src/useremul/), and cleaning up some more legacy constructs. Adding -Wstrict-aliasing and -fstrict-aliasing detection to the configure script. 20070606 Adding a check for broken GCC on Solaris to the configure script. (GCC 3.4.3 on Solaris cannot handle static variables which are initialized to 0 or NULL. :-/) Removing the old (non-working) ARC emulation modes: NEC RD94, R94, R96, and R98, and the last traces of Olivetti M700 and Deskstation Tyne. Removing the non-working skeleton WDSC device (dev_wdsc). 20070607 Thinking about how to use the host's cc + ld at runtime to generate native code. (See experiments/native_cc_ld_test.i for an example.) 20070608 Adding a program counter sampling timer, which could be useful for native code generation experiments. The KN02_CSR_NRMMOD bit in the DECstation 5000/200 (KN02) CSR should always be set, to allow a 5000/200 PROM to boot. 20070609 Moving out breakpoint details from the machine struct into a helper struct, and removing the limit on max nr of breakpoints. 20070610 Moving out tick functions into a helper struct as well (which also gets rid of the max limit). 20070612 FINALLY figured out why Debian/DECstation stopped working when translation read-ahead was enabled: in src/memory_rw.c, the call to invalidate_code_translation was made also if the memory access was an instruction load (if the page was mapped as writable); it shouldn't be called in that case. 20070613 Implementing some more MIPS32/64 revision 2 instructions: di, ei, ext, dext, dextm, dextu, and ins. 20070614 Implementing an instruction combination for the NetBSD/arm idle loop (making the host not use any cpu if NetBSD/arm inside the emulator is not using any cpu). Increasing the nr of ARM VPH entries from 128 to 384. 20070615 Removing the ENABLE_arch stuff from the configure script, so that all included architectures are included in both release and development builds. Moving memory related helper functions from misc.c to memory.c. Adding preliminary instructions for netbooting NetBSD/pmppc to guestoses.html; it doesn't work yet, there are weird timeouts. Beginning a total rewrite of the userland emulation modes (removing all emulation modes, beginning from scratch with NetBSD/MIPS and FreeBSD/Alpha only). 20070616 After fixing a bug in the DEC21143 NIC (the TDSTAT_OWN bit was only cleared for the last segment when transmitting, not all segments), NetBSD/pmppc boots with root-on-nfs without the timeouts. Updating guestoses.html. Removing the skeleton PSP (Playstation Portable) mode. Moving X11-related stuff in the machine struct into a helper struct. Cleanup of out-of-memory checks, to use a new CHECK_ALLOCATION macro (which prints a meaningful error message). Adding a COMMENT to each machine and device (for automagic .index comment generation). Doing regression testing for the next release. ============== RELEASE 0.4.6 ==============
