short term:----------- support variable tsc freq- cpu_interrupt() win32/SMP fix- USB host async- IDE async- debug option in 'configure' script + disable -fomit-frame-pointer- Precise VGA timings for old games/demos (malc patch)- merge PIC spurious interrupt patch- merge Solaris patch- warning for OS/2: must not use 128 MB memory (merge bochs cmos patch ?)- 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- 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)ppc specific:------------- TLB invalidate not needed if msr_pr changes- SPR_ENCODE() not useful- enable shift optimizations ?linux-user specific:-------------------- add IPC syscalls- handle rare page fault cases (in particular if page fault in helpers or  in syscall emulation code).- 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.- fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID)- use kernel traps for unaligned accesses on ARM ?lower priority:--------------- int15 ah=86: use better timing- suppress shift_mem ops- fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)- optimize FPU operations (evaluate x87 stack pointer statically)- use -msoft-float on ARM
