2010-05-06qemu: address todo comment in exec.cMichael S. Tsirkin
exec.c has a comment 'XXX: optimize' for lduw_phys/stw_phys, so let's do it, along the lines of stl_phys. The reason to address 16 bit accesses specifically is that virtio relies on these accesses to be done atomically, using memset as we do now breaks this assumption, which is reported to cause qemu with kvm to read wrong index values under stress. https://bugzilla.redhat.com/show_bug.cgi?id=525323 Signed-off-by: Michael S.

Avoid loading linux-user applications in address space already used/reserved by the host. Signed-off-by: Paul Brook <paul@codesourcery.com>
2010-05-05Remove PAGE_RESERVEDPaul Brook
The usermode PAGE_RESERVED code is not required by the current mmap implementation, and is already broken when guest_base != 0. Unfortunately the bsd emulation still uses the old mmap implementation, so we can't rip it out altogether. Signed-off-by: Paul Brook <paul@codesourcery.com>

Linux AIO is aonly used by system emulation, so should not be linked into the userspace emulatior. Signed-off-by: Paul Brook <paul@codesourcery.com>
2010-05-05Enable -d cpu logging by default.Richard Henderson
When -d cpu logging was handled by target-foo/translate.c, it was controled by DEBUG_DISAS, which is enabled by default. Use the same condition in cpu_exec. At the same time, reduce the if-deffery by assuming no flags update is required for the target. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-05-03hw: better i440 emulationBernhard M. Wiedemann
updated version of an old patch http://xenon.stanford.edu/~eswierk/misc/qemu-linuxbios/qemu-piix-ram-size.patch that together with http://www.mail-archive.com/linuxbios@linuxbios.org/msg02390.html (which is already in coreboot trunk) allows coreboot to autodetect the amount of RAM within qemu/kvm from a register in i440 northbridge. The message on the old patch states: Unfortunately the current version of qemu does not set these registers, but I have patched qemu so that it emulates the i440 more faithfully in this regard.

2010-05-03fix whitespace bogon in some versions of makeNathan Froyd
With three different make binaries I have available, configuring a pristine QEMU tree and attempting to make gives the cryptic: Makefile:27: *** missing separator. Stop. This patch fixes it (presumably because it makes the output of `set-vpath' be an empty string, rather than a bit of whitespace), but I don't understand why this hasn't been a problem for other folks before.

2010-05-03QMP: Introduce RESUME eventLuiz Capitulino
It's emitted when the Virtual Machine resumes execution. We currently have the STOP event but don't have the matching RESUME one, this means that clients are notified when the VM is stopped but don't get anything when it resumes.
