short term:
----------
-- handle fast timers + add explicit clocks
-- OS/2 install bug
-- handle Self Modifying Code even if modifying current TB (BE OS 5 install)
-- physical memory cache (reduce qemu-fast address space size to about 32 MB)
-- better code fetch
-- XP security bug
- cycle counter for all archs
-- TLB code protection support for PPC
-- add sysenter/sysexit and fxsr for L4 pistachio 686
+- cpu_interrupt() win32/SMP fix
+- support variable tsc freq
+- 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
+- warning for OS/2: must not use 128 MB memory (merge bochs cmos patch ?)
+- config file (at least for windows/Mac OS X)
+- update doc: PCI infos.
- basic VGA optimizations
-- disable SMC handling for ARM/SPARC/PPC
+- better code fetch (different exception handling + CS.limit support)
+- do not resize vga if invalid size.
+- avoid looping if only exceptions
+- 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
-- cmos clock update and timers
- 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
-lower priority:
---------------
-- 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)
+ppc specific:
+------------
+- TLB invalidate not needed if msr_pr changes
+- enable shift optimizations ?
+
+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 heplers or
+- 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
+- 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
