-short term:
-----------
-- support variable tsc freq
+General:
+-------
+- cycle counter for all archs
- cpu_interrupt() win32/SMP fix
-- 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
-- merge Solaris patch
- warning for OS/2: must not use 128 MB memory (merge bochs cmos patch ?)
- config file (at least for windows/Mac OS X)
-- commit message if execution of code in IO memory
- update doc: PCI infos.
-- VNC patch + Synaptic patch.
- basic VGA optimizations
-- physical memory cache (reduce qemu-fast address space size to about 32 MB)
-- better code fetch (different exception handling + CS.limit support)
+- better code fetch
- do not resize vga if invalid size.
-- avoid looping if only exceptions
-- cycle counter for all archs
- 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()).
-- fix arm fpu rounding (at least for float->integer conversions)
ppc specific:
------------
- TLB invalidate not needed if msr_pr changes
-- SPR_ENCODE() not useful
- 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).
+- remove threading support as it cannot work at this point
+- improve IPC syscalls
- 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
