short term: |
|---|---|
| 2 |
---------- |
| 3 |
- debug option in 'configure' script + disable -fomit-frame-pointer |
| 4 |
- Precise VGA timings for old games/demos (malc patch) |
| 5 |
- merge PIC spurious interrupt patch |
| 6 |
- merge Solaris patch |
| 7 |
- warning for OS/2: must not use 128 MB memory (merge bochs cmos patch ?) |
| 8 |
- config file (at least for windows/Mac OS X) |
| 9 |
- commit message if execution of code in IO memory |
| 10 |
- update doc: PCI infos. |
| 11 |
- VNC patch + Synaptic patch. |
| 12 |
- basic VGA optimizations |
| 13 |
- physical memory cache (reduce qemu-fast address space size to about 32 MB) |
| 14 |
- better code fetch (different exception handling + CS.limit support) |
| 15 |
- do not resize vga if invalid size. |
| 16 |
- avoid looping if only exceptions |
| 17 |
- cycle counter for all archs |
| 18 |
- TLB code protection support for PPC |
| 19 |
- see openMosix Doc |
| 20 |
- disable SMC handling for ARM/SPARC/PPC (not finished) |
| 21 |
- see undefined flags for BTx insn |
| 22 |
- user/kernel PUSHL/POPL in helper.c |
| 23 |
- keyboard output buffer filling timing emulation |
| 24 |
- return UD exception if LOCK prefix incorrectly used |
| 25 |
- test ldt limit < 7 ? |
| 26 |
- tests for each target CPU |
| 27 |
- fix CCOP optimisation |
| 28 |
- fix all remaining thread lock issues (must put TBs in a specific invalid |
| 29 |
state, find a solution for tb_flush()). |
| 30 |
- fix arm fpu rounding (at least for float->integer conversions) |
| 31 |
- SMP support |
| 32 |
|
| 33 |
ppc specific: |
| 34 |
------------ |
| 35 |
- TLB invalidate not needed if msr_pr changes |
| 36 |
- SPR_ENCODE() not useful |
| 37 |
- enable shift optimizations ? |
| 38 |
|
| 39 |
lower priority: |
| 40 |
-------------- |
| 41 |
- more friendly BIOS (logo) |
| 42 |
- int15 ah=86: use better timing |
| 43 |
- suppress shift_mem ops |
| 44 |
- fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret) |
| 45 |
- optimize FPU operations (evaluate x87 stack pointer statically) |
| 46 |
- add IPC syscalls |
| 47 |
- use -msoft-float on ARM |
| 48 |
- use kernel traps for unaligned accesses on ARM ? |
| 49 |
- handle rare page fault cases (in particular if page fault in helpers or |
| 50 |
in syscall emulation code). |
| 51 |
- fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID) |
| 52 |
- more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit |
| 53 |
issues, fix 16 bit uid issues) |
| 54 |
- use page_unprotect_range in every suitable syscall to handle all |
| 55 |
cases of self modifying code. |
| 56 |
- use gcc as a backend to generate better code (easy to do by using |
| 57 |
op-i386.c operations as local inline functions). |
