2013-07-01PPC: Add non-kvm stub fileAlexander Graf
There are cases where a kvm provided function is called from generic hw code that doesn't know whether kvm is available or not. Provide a stub file which can provide simple replacement functions for those cases. Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com>
2013-07-01KVM: PIC: Only commit irq routing when necessaryAlexander Graf
The current logic updates KVM's view of our interrupt map every time we change it. While this is nice and bullet proof, it slows things down badly for me. QEMU spends about 3 seconds on every start telling KVM what news it has on its routing maps. Instead, let's just synchronize the whole irq routing map as a whole when we're done constructing it. For things that change during runtime, we can still update the routing table on demand. Signed-off-by: Alexander Graf <agraf@suse.de>

2013-07-01KVM: MSI: Swap payload to native endiannessAlexander Graf
The usual MSI injection mechanism writes msi.data into memory using an le32 wrapper. So on big endian guests, this swaps msg.data into the expected byte order. For irqfd however, we don't swap the payload right now, rendering in-kernel MPIC emulation broken on PowerPC. Swap msg.data to the correct endianness whenever we touch it. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-01KVM: Export kvm_init_irq_routingAlexander Graf
On PPC, we can have different types of interrupt controllers, so we really only know that we are going to use one when we created it. Export kvm_init_irq_routing() to common code, so that we don't have to call kvm_irqchip_create(). Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-01KVM: Don't assume that mpstate exists with in-kernel PIC alwaysAlexander Graf
On PPC, we don't support MP state. So far it's not necessary and I'm not convinced yet that we really need to support it ever. However, the current idle logic in QEMU assumes that an in-kernel PIC also means we support MP state. This assumption is not true anymore. Let's split up the two cases into two different variables. That way PPC can expose an in-kernel PIC, while not implementing MP state. Signed-off-by: Alexander Graf <agraf@suse.de> CC: Jan Kiszka <jan.kiszka@siemens.com>

2013-06-28qemu-char: Fix ID reuse after chardev-remove for qapi-based initMarkus Armbruster
Commit 2c5f488 introduced qapi-based character device initialization as a new code path in qemu_chr_new_from_opts(). Unfortunately, it failed to store parameter opts in the new chardev. Therefore, qemu_chr_delete() doesn't delete it. Even though the device is gone, its options linger, and any attempt to create another one with the same ID fails.

Also use CAIRO_FORMAT_RGB24 unconditionally. DisplaySurfaces will never ever see 8bpp surfaces.

2013-06-28vl: convert -smp to qemu_opts_parse()Michael Tokarev
This also introduces a new suboption, "cpus=", which is the default. So after this patch, -smp n,sockets=y is the same as -smp cpus=n,sockets=y (with "cpu" being some generic thing, referring to either cores, or threads, or sockets, as before). We still don't validate relations between different numbers, for example it is still possible to say -smp 1,sockets=10 and it will be accepted to mean sockets=1.

2013-06-28multiboot: Calculate upper_mem in the ROMKevin Wolf
The upper_mem field of the Multiboot information struct doesn't really contain the RAM size - 1 MB like we used to calculate it, but only the memory from 1 MB up to the first (upper) memory hole. In order to correctly retrieve this information, the multiboot ROM now looks at the mmap it creates anyway and tries to find the size of contiguous usable memory from 1 MB. Drop the multiboot.c definition of lower_mem and upper_mem because both are queried at runtime now.

2013-06-28multiboot: Don't forget last mmap entryKevin Wolf
When the BIOS returns ebx = 0, the current entry is still valid and needs to be included in the Multiboot memory map. Fixing this meant that using bx as the entry index doesn't work any more because it's 0 on the last entry (and it was SeaBIOS-specific anyway), so the whole loop had to change a bit and should be more generic as a result (ebx can be an arbitrary continuation number now, and the entry size returned by the BIOS is used instead of hard-coding 20 bytes).

2013-06-28arch_init: Fix format string by using RAM_ADDR_FMTStefan Weil
length is a ram_addr_t, so RAM_ADDR_FMT must be used instead of %ld. This fixes a recently introduced regression for w64 builds. Using RAM_ADDR_FMT also changes decimal output to sedecimal. This is good here because length and block->length should both use the same base in the error message.

2013-06-28block: change default of .has_zero_init to 0Peter Lieven
.has_zero_init defaults to 1 for all formats and protocols. this is a dangerous default since this means that all new added drivers need to manually overwrite it to 0 if they do not ensure that a device is zero initialized after bdrv_create(). if a driver needs to explicitly set this value to 1 its easier to verify the correctness in the review process. during review of the existing drivers it turned out that ssh and gluster had a wrong default of 1. both protocols support host_devices as backend which are not by default zero initialized. this wrong assumption will lead to possible corruption if qemu-img convert is used to write to such a backend. vpc and vmdk also defaulted to 1 altough they support fixed respectively flat extends. this has to be addresses in separate patches. both formats as well as the mentioned ssh and gluster are turned to the default of 0 with this patch for safety. a similar problem with the wrong default existed for iscsi most likely because the driver developer did oversee the default value of 1.
