short term:
----------
+- 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
- 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
- basic VGA optimizations
-- disable SMC handling for ARM/SPARC/PPC
+- 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
lower priority:
--------------
+- 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
