| short term: |
| ---------- |
| - handle fast timers + add explicit clocks |
| - OS/2 install bug |
| - win 95 install bug |
| - handle Self Modifying Code even if modifying current TB (BE OS 5 install) |
| - physical memory cache (reduce qemu-fast address space size to about 32 MB) |
| - better code fetch |
| - XP security bug |
| - cycle counter for all archs |
| - TLB code protection support for PPC |
| - add sysenter/sysexit and fxsr for L4 pistachio 686 |
| - basic VGA optimizations |
| - disable SMC handling for ARM/SPARC/PPC |
| - 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 |
| - cmos clock update and timers |
| - 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 |
| |
| lower priority: |
| -------------- |
| - suppress shift_mem ops |
| - fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret) |
| - sysenter/sysexit emulation |
| - 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 heplers 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). |
| - add SSE2/MMX operations |
