2012-11-02migration: use migrate_fd_close in migrate_fd_cleanupPaolo Bonzini1-11/+8
migrate_fd_cleanup will usually close the file descriptor via buffered_file_close's call to migrate_fd_close. However, in the case of s->file == NULL it is "inlining" migrate_fd_close (almost: there is a direct close() instead of using s->close(s)). To fix the inconsistency and clean up the code, allow multiple calls to migrate_fd_close and use the function in migrate_fd_cleanup. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Now that qemu_fseek does not exist anymore, there is no reason to do an fseek before fread/fwrite when operating on an stdio file. Thus, unify the get/put_buffer callbacks used by qemu_fopen with those used for pipes. Reviewed-by: Orit Wasserman <owasserm@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2012-11-01arm_boot: Change initrd load address to "halfway through RAM"Peter Maydell2-15/+26
To avoid continually having to bump the initrd load address to account for larger kernel images, put the initrd halfway through RAM. This allows large kernels on new boards with lots of RAM to work OK, without breaking existing usecases for boards with only 32MB of RAM. Note that this change fixes in passing a bug where we were passing an overly large max_size to load_image_targphys() for the initrd, which meant that we wouldn't correctly refuse to load an enormous initrd that didn't actually fit into RAM.

2012-11-01pixman/vnc: use pixman images in vnc.Gerd Hoffmann7-228/+259
The vnc code uses *three* DisplaySurfaces: First is the surface of the actual QemuConsole, usually the guest screen, but could also be a text console (monitor/serial reachable via Ctrl-Alt-<nr> keys). This is left as-is. Second is the current server's view of the screen content. The vnc code uses this to figure which parts of the guest screen did _really_ change to reduce the amount of updates sent to the vnc clients. It is also used as data source when sending out the updates to the clients. This surface gets replaced by a pixman image. The format changes too, instead of using the guest screen format we'll use fixed 32bit rgb framebuffer and convert the pixels on the fly when comparing and updating the server framebuffer. Third surface carries the format expected by the vnc client. That isn't used to store image data. This surface is switched to PixelFormat and a boolean for bigendian byte order.

Depending on whenever vga_update_text() or vga_draw_text() happens to be called first only the text display or only the graphics display will see display resolution changes and full redraws.

2012-11-01target-ppc: Extend FPU state for newer POWER CPUsDavid Gibson3-14/+27
This patch adds some extra FPU state to CPUPPCState. Specifically, fpscr is extended to a target_ulong bits, since some recent (64 bit) CPUs now have more status bits than fit inside 32 bits. Also, we add the 32 VSR registers present on CPUs with VSX (these extend the standard FP regs, which together with the Altivec/VMX registers form a 64 x 128bit register file for VSX). We don't actually support the instructions using these extra registers in TCG yet, but we still need a place to store the state so we can sync it with KVM and savevm/loadvm it. This patch updates the savevm code to not fail on the extended state, but also does not actually save it - that's a project for another patch.

2012-11-01e1000: pre-initialize RAH/RAL registersGabriel L. Somlo1-0/+10
Some guest operating systems' drivers (Mac OS X in particular) fail to properly initialize the Receive Address registers (probably expecting them to be pre-initialized by an earlier component, such as a specific proprietary BIOS). This patch pre-initializes the RA registers, allowing OS X networking to function properly. Other guest operating systems are not affected, and free to (re)initialize these registers during boot. [According to the datasheet the Address Valid bits in the RA registers are cleared on PCI or software reset. This patch adds the NIC's MAC address and sets Address Valid on reset. So we diverge from real hardware behavior here. -- Stefan] Signed-off-by: Gabriel Somlo <somlo@cmu.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2012-11-01net: Reject non-netdevs in qmp_netdev_del()Stefan Hajnoczi1-1/+8
The netdev_del command crashes when given a -net device, because it calls qemu_opts_del(NULL). Check that this is a -netdev before attempting to delete it and the QemuOpts. Note the subtle change from qemu_find_opts_err("netdev", errp) to qemu_find_opts_err("netdev", NULL). Since "netdev" is a built in options group and we don't check for NULL return anyway, there's no use in passing errp here. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
