2014-09-22async: aio_context_new(): Handle event_notifier_init failureChrysostomos Nanakos2-2/+2
On a system with a low limit of open files the initialization of the event notifier could fail and QEMU exits without printing any error information to the user. The problem can be easily reproduced by enforcing a low limit of open files and start QEMU with enough I/O threads to hit this limit. The same problem raises, without the creation of I/O threads, while QEMU initializes the main event loop by enforcing an even lower limit of open files. This commit adds an error message on failure: # qemu [...] -object iothread,id=iothread0 -object iothread,id=iothread1 qemu: Failed to initialize event notifier: Too many open files in system Signed-off-by: Chrysostomos Nanakos <cnanakos@grnet.gr> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2014-09-18qdev: Move global validation to a single functionEduardo Habkost1-5/+5
Currently GlobalProperty.not_used=false has multiple meanings: * It may be a property for a hotpluggable device, which may or may not have been used by a device; * It may be a machine-type-provided property, which may or may not have been used by a device. * It may be a user-provided property that was actually not used by any device. Simplify the logic by having two separate fields: 'user_provided' and 'used'. This allows the entire global property validation logic to be contained in a single function, and allows more specific error messages.

2014-09-10block: Make the block accounting functions operate on BlockAcctStatsBenoît Canet2-5/+8
This is the next step for decoupling block accounting functions from BlockDriverState. In a future commit the BlockAcctStats structure will be moved from BlockDriverState to the device models structures. Note that bdrv_get_stats was introduced so device models can retrieve the BlockAcctStats structure of a BlockDriverState without being aware of it's layout. This function should go away when BlockAcctStats will be embedded in the device models structures.

2014-09-10block: Extract the block accounting codeBenoît Canet5-24/+60
The plan is to add new accounting metrics (latency, invalid requests, failed requests, queue depth) and block.c is overpopulated so it will be better to work in a separate module. Moreover the long term plan is to have statistics in each of the BDS of the graph for metrology purpose; this means that the device model statistics must move from the topmost BDS to the device model. So we need to decouple the statistic code from BlockDriverState. This is another argument for the extraction of the code in a separate module.

2014-09-08spapr_pci: map the MSI window in each PHBGreg Kurz2-3/+1
On sPAPR, virtio devices are connected to the PCI bus and use MSI-X. Commit cc943c36faa192cd4b32af8fe5edb31894017d35 has modified MSI-X so that writes are made using the bus master address space and follow the IOMMU path. Unfortunately, the IOMMU address space address space does not have an MSI window: the notification is silently dropped in unassigned_mem_write instead of reaching the guest... The most visible effect is that all virtio devices are non-functional on sPAPR since then. :( This patch does the following: 1) map the MSI window into the IOMMU address space for each PHB - since each PHB instantiates its own IOMMU address space, we can safely map the window at a fixed address (SPAPR_PCI_MSI_WINDOW) - no real need to keep the MSI window setup in a separate function, the spapr_pci_msi_init() code moves to spapr_phb_realize(). 2) kill the global MSI window as it is not needed in the end Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2014-09-08KVM: Add helper to run KVM_CHECK_EXTENSION on vm fdAlexander Graf1-0/+2
We now can call KVM_CHECK_EXTENSION on the kvm fd or on the vm fd, whereas the vm version is more accurate when it comes to PPC KVM. Add a helper to make the vm version available that falls back to the non-vm variant if the vm one is not available yet to stay compatible. Signed-off-by: Alexander Graf <agraf@suse.de>
2014-09-08spapr: Locate RTAS and device-tree based on real RMABenjamin Herrenschmidt1-1/+2
We currently calculate the final RTAS and FDT location based on the early estimate of the RMA size, cropped to 256M on KVM since we only know the real RMA size at reset time which happens much later in the boot process. This means the FDT and RTAS end up right below 256M while they could be much higher, using precious RMA space and limiting what the OS bootloader can put there which has proved to be a problem with some OSes (such as when using very large initrd's) Fortunately, we do the actual copy of the device-tree into guest memory much later, during reset, late enough to be able to do it using the final RMA value, we just need to move the calculation to the right place. However, RTAS is still loaded too early, so we change the code to load the tiny blob into qemu memory early on, and then copy it into guest memory at reset time. It's small enough that the memory usage doesn't matter.

2014-09-08loader: Add load_image_size() to replace load_image()Benjamin Herrenschmidt1-0/+1
A subsequent patch to ppc/spapr needs to load the RTAS blob into qemu memory rather than target memory (so it can later be copied into the right spot at machine reset time). I would use load_image() but it is marked deprecated because it doesn't take a buffer size as argument, so let's add load_image_size() that does.

2014-09-08PPC: mac99: Move NVRAM to page boundary when necessaryAlexander Graf1-1/+1
When running KVM we have to adhere to host page boundaries for memory slots. Unfortunately the NVRAM on mac99 is a 4k RAM hole inside of an MMIO flash area. So if our host is configured with 64k page size, we can't use the mac99 target with KVM. This is a real shame, as this limitation is not really an issue - we can easily map NVRAM somewhere else and at least Linux and Mac OS X use it at their new location. So in that emergency case when it's about failing to run at all and moving NVRAM to a place it shouldn't be at, choose the latter. This patch enables -M mac99 with KVM on 64k page size hosts.

2014-09-08ppc: spapr-rtas - implement os-term rtas callNikunj A Dadhania1-2/+1
PAPR compliant guest calls this in absence of kdump. This finally reaches the guest and can be handled according to the policies set by higher level tools(like taking dump) for further analysis by tools like crash. Linux kernel calls ibm,os-term when extended property of os-term is set. This makes sure that a return to the linux kernel is gauranteed.
