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
|
|
- 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
|
|
- 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)
|
|
- SMP support
|
|
|
|
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)
|
|
- 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
|
|
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
