[Qemu-devel] QEMU 0.5.2

[Fabrice Bellard]

Hi,

QEMU 0.5.2 is out. A statically linked binary distribution for i386 is 
also available. There are still many known problems (see the TODO list 
!), but more OSes are working.

version 0.5.2:

  - improved soft MMU speed (assembly functions and specializing)
  - improved multitasking speed by avoiding flushing TBs when
    switching tasks
  - improved qemu-fast speed
  - improved self modifying code handling (big performance gain in
    softmmu mode).
  - fixed IO checking
  - fixed CD-ROM detection (win98 install CD)
  - fixed addseg real mode bug (GRUB boot fix)
  - added ROM memory support (win98 boot)
  - fixed 'call Ev' in case of paging exception
  - updated the script 'qemu-binfmt-conf.sh' to use QEMU automagically
    when launching executables for the supported target CPUs.
  - PowerPC system emulation update (Jocelyn Mayer)
  - PC floppy emulation and DMA fixes (Jocelyn Mayer)
  - polled mode for PIC (Jocelyn Mayer)
  - fixed PTE dirty bit handling
  - fixed xadd same reg bug
  - fixed cmpxchg exception safeness
  - access to virtual memory in gdb stub
  - task gate and NT flag fixes
  - eflags optimisation fix for string operations
