-before 0.5.2:
-------------
-
-- TLB code protection support
-- basic VGA optimizations
-- disable SMC handling for ARM/SPARC/PPC
-
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
+- 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 (not finished)
+- see undefined flags for BTx insn
- user/kernel PUSHL/POPL in helper.c
- keyboard output buffer filling timing emulation
-- verify tb_flush() with a20 and TLBs
-
-- cmos clock update and timers
+- return UD exception if LOCK prefix incorrectly used
- 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
-- optimize FPU operations (evaluate x87 stack pointer statically) and
- fix cr0.TS 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 ?
