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
|
|
- 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
|
|
- 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
|
|
- 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()).
|
|
|
|
ppc specific:
|
|
------------
|
|
- TLB invalidate not needed if msr_pr changes
|
|
- enable shift optimizations ?
|
|
|
|
linux-user specific:
|
|
-------------------
|
|
- add IPC syscalls
|
|
- handle rare page fault cases (in particular if page fault in helpers or
|
|
in syscall emulation code).
|
|
- 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.
|
|
- 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
