short term: ---------- - debug option in 'configure' script + disable -fomit-frame-pointer - Solaris display error with Cirrus VGA (http://lists.gnu.org/archive/html/qemu-devel/2004-10/msg00390.html). - Precise VGA timings for old games/demos (malc patch) - merge PIC spurious interrupt patch - merge VNC keyboard patch - merge Solaris patch - merge ARM patches + self modifying code patch (Paul Brook) - warning for OS/2: must not use 128 MB memory - config file (at least for windows/Mac OS X) - commit message if execution of code in IO memory - update doc: PCI infos. - VNC patch + Synaptic patch. - basic VGA optimizations - test sysenter/sysexit and fxsr for L4 pistachio 686 - physical memory cache (reduce qemu-fast address space size to about 32 MB) - better code fetch (different exception handling + CS.limit support) - do not resize vga if invalid size. - avoid looping if only exceptions - cycle counter for all archs - TLB code protection support for PPC - see openMosix Doc - disable SMC handling for ARM/SPARC/PPC (not finished) - see undefined flags for BTx insn - user/kernel PUSHL/POPL in helper.c - keyboard output buffer filling timing emulation - return UD exception if LOCK prefix incorrectly used - test ldt limit < 7 ? - tests for each target CPU - fix CCOP optimisation - fix all remaining thread lock issues (must put TBs in a specific invalid state, find a solution for tb_flush()). - fix arm fpu rounding (at least for float->integer conversions) - SMP support ppc specific: ------------ - TLB invalidate not needed if msr_pr changes - endianness bugs in do_load_fpscr and do_store_fpscr - SPR_ENCODE() not useful - enable shift optimizations ? lower priority: -------------- - more friendly BIOS (logo) - int15 ah=86: use better timing - HDD geometry in CMOS (not used except for very old DOS programs) - suppress shift_mem ops - fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret) - sysenter/sysexit emulation - optimize FPU operations (evaluate x87 stack pointer statically) - add IPC syscalls - use -msoft-float on ARM - use kernel traps for unaligned accesses on ARM ? - handle rare page fault cases (in particular if page fault in helpers or in syscall emulation code). - fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID) - more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit issues, fix 16 bit uid issues) - use page_unprotect_range in every suitable syscall to handle all cases of self modifying code. - use gcc as a backend to generate better code (easy to do by using op-i386.c operations as local inline functions). - add SSE2/MMX operations
