 short term:
 ----------
+- cycle counter for all archs
+- cpu_interrupt() win32/SMP fix
+- support variable tsc freq
+- USB host async
+- IDE async
 - debug option in 'configure' script + disable -fomit-frame-pointer
-- VGA font change fix
-- PIC spurious interrupt patch
-- 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
+- Precise VGA timings for old games/demos (malc patch)
+- merge PIC spurious interrupt 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
-- 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 
+- 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

 - 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)
+linux-user specific:
+-------------------
 - 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
