2009-11-11Reject late rom loadingPaul Brook
rom_+add_file/rom_add_blob only work correctly if called before load_all_roms. Enforce this rather than silently accepting and putting the rom in the wrong place at reset. Signed-off-by: Paul Brook <paul@codesourcery.com>

2009-11-09QemuOpts: command line switches for the config file.Gerd Hoffmann
Adds -readconfig and -writeconfig command line switches to read/write QemuOpts from config file. In theory you should be able to do: qemu < machine config cmd line switches here > -writeconfig vm.cfg qemu -readconfig vm.cfg In practice it will not work. Not all command line switches are converted to QemuOpts, so you'll have to keep the not-yet converted ones on the second line. Also there might be bugs lurking which prevent even the converted ones from working correctly. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-09Documentation: Don't mention old qemu-img optionsKevin Wolf
The old options are still supported for compatibility, but they are inconsistent (for example create -b vs. convert -B for backing files) and incomplete (-F only exists for create) which tends to confuse people.

2009-11-09eepro100: Improve support for different devicesStefan Weil
* Add device properties (size of statistical data, extended tcb support) to EEPRO100State and set these values for the different devices. * Fix PCI configuration for existing devices. * Add initialisation code for missing devices. * Remove function device_supports_eTxCB. It is no longer needed. * Fix dump of statistical data. It now respects the real size of the statistical data. An endianess issue was fixed here, too. * CU_SHOWSTATS, CU_DUMPSTATS now write a completion value after the statistical data. There is no need to keep this value in eepro100_stats_t, so member "complete" could be removed. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-09pci: implement pci bridge filtering.Isaku Yamahata
This patch implements pci bridge filtering. TODO: currently almost all the map funcions assumes filtered_size == size and addr & ~(size - 1) == addr. However with bridge filtering, they aren't always true. Teach them such cases, such that filtered_size < size and addr & (size - 1) != 0.

2009-11-09pci: initialize pci config headers depending it pci header type.Isaku Yamahata
- Only sets default subsystem id for header type 00.(normal header type) because header type 01 doesn't have subsystem id, and uses the register for other purpose. So setting default subsystem id doesn't make sense. - initialize wmask more for header type 01.(bridge header type) Without those wmasks, linux was confused not boot, and lspci was confused not to print out expected IO/memory range.

2009-11-09pci: teach pci_default_config_write() ROM bar for normal/bridge device .Isaku Yamahata
When updated ROM expantion address of header type 0, it missed to update mappings. Add PCI_ROM_ADDRESS check whether to call pci_update_mappings() Also update pci mapping when PCI_ROM_ADDRESS1 is written for header type 1. pci_update_mapping() path isn't performance critical, so call it even independent of header type.

2009-11-09pci: add helper functions to check ranges overlap.Isaku Yamahata
add helper function to check ranges overlap suggested by Michael S. Tsirkin <mst@redhat.com>. His original suggestion was to use [first, last], however I chosen to use offset, length pair, i.e. [offset, offset + length) because pci configuration space related functions all uses offset and length pair, so it helps to avoid to type constant twice.

2009-11-09pci: make pci configuration transaction more accurate.Isaku Yamahata
This patch sorts out/enhances pci code to track pci bus topology more accurately. - Track host bus bridge with pci domain number. Although the current qemu implementation supports only pci domian 0 yet. - Track pci bridge parent-child relationship. When looking down from pci host bus for pci sub bus, be aware of secondary bus/subordinate bus. Thus pci configuration transaction is more accurately emulated. This patch adds new member to PCIBus to track pci bus topology. Since qdev already tracks down bus relationship, those new member wouldn't be necessary. However it would be addressed later because not all the pci device isn't converted to qdev yet.

2009-11-09pci: 64bit bar support.Isaku Yamahata
implemented pci 64bit bar support. The tricky bit is pci_update_mapping(). An OS is allowed to set the BAR such that OS can't address the area pointed by BAR. It doesn't make sense, though. In that case, don't map the BAR. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-09pci: typedef pcibus_t as uint64_t instead of uint32_t.Isaku Yamahata
This patch is preliminary for 64bit bar. For 64bit bar support, change pcibus_t which represents pci bus addr/size from uint32_t to uint64_t. And also change FMT_pcibus for printf. In pci_update_mapping() checks 32bit overflow. So the check must be updated too. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-09pci_host.h: move functions in pci_host.h into .c file.Isaku Yamahata
split static functions in pci_host.h into pci_host.c and pci_host_template.h. Later a structures declared in pci_host.h, PCIHostState, will be used. However pci_host.h doesn't allow to include itself easily. This patches addresses it. pci_host.h includes functions which are instantiated in .c by including pci_host.h with typedefing pci_addr_t. pci_addr_t is per pci host bridge and is typedef'ed to uint32_t for ioio or target_phys_addr_t for mmio in .c file. That prevents from including pci_host.h to use PCIHostState because of requiring type, pci_addr_t. Its purpose to include is to instantiate io function for mmio or ioio depending on which pci host bridge requires ioio or mmio. To avoid including code, we always instantiate both version.

- use symbolic constant - use helper function pci_set_xxx() - removed lines which initializes to 0. It is unnecessary because it is already zeroed. - add some comments on command registers.

2009-11-09whitelist host virtio networking featuresDustin Kirkland
This patch is a followup to 8eca6b1bc770982595db2f7207c65051572436cb, fixing crashes when guests with 2.6.25 virtio drivers have saturated virtio network connections. https://bugs.edge.launchpad.net/ubuntu/+source/qemu-kvm/+bug/458521 That patch should have been whitelisting *_HOST_* rather than the the *_GUEST_* features. I tested this by running an Ubuntu 8.04 Hardy guest (2.6.24 kernel + 2.6.25-virtio driver). I saturated both the incoming, and outgoing network connection with nc, seeing sustained 6MB/s up and 6MB/s down bitrates for ~20 minutes. Previously, this crashed immediately. Now, the guest does not crash and maintains network connectivity throughout the test.
