| short term: |
| ---------- |
| - 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) |
| - 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) |
| - SMP support |
| |
| ppc specific: |
| ------------ |
| - TLB invalidate not needed if msr_pr changes |
| - SPR_ENCODE() not useful |
| - enable shift optimizations ? |
| |
| lower priority: |
| -------------- |
| - more friendly BIOS (logo) |
| - 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) |
| - 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 helpers 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). |
