2010-02-19net: Fix bogus "Warning: vlan 0 with no nics" with -deviceMarkus Armbruster
net_check_clients() prints this when an VLAN has host devices, but no guest devices. It uses VLANState members nb_guest_devs and nb_host_devs to keep track of these devices. However, -device does not update nb_guest_devs, only net_init_nic() does that, for -net nic. Check the VLAN clients directly, and remove the counters.

Since b567b38 (target-arm: remove T0 and T1, 2009-10-16) the only global register that is used is AREG0, so the complexity of hostregs_helper.h is unused.

When compiled with CONFIG_DEBUG_TCG, this code looks for missing, duplicate and wrong entries in the op definitions.

2010-02-14PPC: Add timer when running KVMAlexander Graf
For some odd reason we sometimes hang inside KVM forever. I'd guess it's a race condition where we actually have a level triggered interrupt, but the infrastructure can't expose that yet, so the guest ACKs it, goes to sleep and never gets notified that there's still an interrupt pending. As a quick workaround, let's just wake up every 500 ms. That way we can assure that we're always reinjecting interrupts in time. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: Fix large pagesAlexander Graf
We were masking 1TB SLB entries on the feature bit of 16 MB pages. Obviously that breaks, so let's just ignore 1TB SLB entries for now and instead do 16MB pages correctly. This fixes PPC64 Linux boot with -m above 256. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: Add USB per default on U3Alexander Graf
Linux with CONFIG_PPC64 doesn't support ADB devices anymore, so we have to use USB for keyboard and mouse. This patch enables USB per default on U3 and adds a virtual keyboard and mouse there. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: Get rid of segfaults in DBDMA emulationAlexander Graf
While trying to find the right channel number for the DBDMA emulation I stumbled across segmentation faults that were purely triggered by the guest. The guest should never have the possiblity to segfault us, so let's check all indirect function calls on a channel, so the code even works for channels that have not been reserved. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: Use macio IDE controller for NewworldAlexander Graf
Per default Linux doesn't come with a lot of storage adapters enabled on Mac configurations. The one that's pretty much always present is the pmac-ide, while the cmd64x is almost never included in any distribution. So let's switch to use the MacIO based IDE controller. There is corresponding OpenBIOS code to get interrupts working properly. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: tell the guest about the time base frequencyAlexander Graf
Our guest systems need to know by how much the timebase increases every second, so there usually is a "timebase-frequency" property in the cpu leaf of the device tree. This property is missing in OpenBIOS. With qemu, Linux's fallback timebase speed and qemu's internal timebase speed match up. With KVM, that is no longer true. The guest is running at the same timebase speed as the host. This leads to massive timing problems. On my test machine, a "sleep 2" takes about 14 seconds with KVM enabled. This patch exports the timebase frequency to OpenBIOS, so it can then put them into the device tree. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: Make interrupts workAlexander Graf
The interrupt code as is didn't really work for me. I couldn't even convince Linux to take interrupt 9 in an interrupt-map. So let's do this right. Let's map all PCI interrupts to 0x1b - 0x1e. That way we're at least a small step closer to what real hardware does. I also took the interrupt pin to line conversion from OpenBIOS, which at least assures us we're compatible with our firmware :-).

2010-02-14PPC: Include dump of lspci -nn on real G5Alexander Graf
To ease debugging and to know what we're lacking, I found it really useful to have an lspci dump of a real U3 based G5 around. So I added a comment for it. If people don't think it's important enough to include this information in the sources, just don't apply this patch. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-02-14PPC: Use Mac99_U3 type on ppc64Alexander Graf
The "Mac99" type so far defines a "U2" based configuration. Unfortunately, there have never been any U2 based PPC64 machines. That's what the U3 was developed for. So let's split the Mac99 machine in a PPC64 and a PPC32 machine. The PPC32 machine stays "Mac99", while the PPC64 one becomes "Mac99_U3". All peripherals stay the same.

2010-02-14PPC: Uninorth config space accessorAlexander Graf
The Uninorth PCI bridge requires different layouts in its PCI config space accessors. This patch introduces a conversion function that makes it compatible with the way Linux accesses it. I also kept an OpenBIOS compatibility hack in. I think it'd be better to take small steps here and do the config space access rework in OpenBIOS later on. When that's done we can remove that hack.

2010-02-14rwhandler: simplified way to register for mem/ioMichael S. Tsirkin
Some users prefer a single callback with length passed as parameter to using b/w/l callbacks. It would maybe be cleaner to just pass length to existing callbacks but that's a lot of churn. So for now add a wrapper. For convenience use pcibus_t for address so a single callback can be used for pci io and pci memory. I did have to resort to preprocessor to reduce code duplication. It is however slightly more straightforward, and better contained than what we had with pci_host_template.h. Again, it would go away if we just passed len to existing callbacks.
