1 short term:
2 ----------
3 - debug option in 'configure' script + disable -fomit-frame-pointer
4 - Solaris display error with Cirrus VGA
5 (http://lists.gnu.org/archive/html/qemu-devel/2004-10/msg00390.html).
6 - Precise VGA timings for old games/demos (malc patch)
7 - merge PIC spurious interrupt patch
8 - merge VNC keyboard patch
9 - merge Solaris patch
10 - merge ARM patches + self modifying code patch (Paul Brook)
11 - warning for OS/2: must not use 128 MB memory
12 - config file (at least for windows/Mac OS X)
13 - commit message if execution of code in IO memory
14 - update doc: PCI infos.
15 - VNC patch + Synaptic patch.
16 - basic VGA optimizations
17 - test sysenter/sysexit and fxsr for L4 pistachio 686
18 - physical memory cache (reduce qemu-fast address space size to about 32 MB)
19 - better code fetch (different exception handling + CS.limit support)
20 - do not resize vga if invalid size.
21 - avoid looping if only exceptions
22 - cycle counter for all archs
23 - TLB code protection support for PPC
24 - see openMosix Doc
25 - disable SMC handling for ARM/SPARC/PPC (not finished)
26 - see undefined flags for BTx insn
27 - user/kernel PUSHL/POPL in helper.c
28 - keyboard output buffer filling timing emulation
29 - return UD exception if LOCK prefix incorrectly used
30 - test ldt limit < 7 ?
31 - tests for each target CPU
32 - fix CCOP optimisation
33 - fix all remaining thread lock issues (must put TBs in a specific invalid
34 state, find a solution for tb_flush()).
35 - fix arm fpu rounding (at least for float->integer conversions)
36 - SMP support
38 ppc specific:
39 ------------
40 - TLB invalidate not needed if msr_pr changes
41 - endianness bugs in do_load_fpscr and do_store_fpscr
42 - SPR_ENCODE() not useful
43 - enable shift optimizations ?
45 lower priority:
46 --------------
47 - more friendly BIOS (logo)
48 - int15 ah=86: use better timing
49 - HDD geometry in CMOS (not used except for very old DOS programs)
50 - suppress shift_mem ops
51 - fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)
52 - sysenter/sysexit emulation
53 - optimize FPU operations (evaluate x87 stack pointer statically)
54 - add IPC syscalls
55 - use -msoft-float on ARM
56 - use kernel traps for unaligned accesses on ARM ?
57 - handle rare page fault cases (in particular if page fault in helpers or
58 in syscall emulation code).
59 - fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID)
60 - more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit
61 issues, fix 16 bit uid issues)
62 - use page_unprotect_range in every suitable syscall to handle all
63 cases of self modifying code.
64 - use gcc as a backend to generate better code (easy to do by using
65 op-i386.c operations as local inline functions).
66 - add SSE2/MMX operations
