2009-11-13Fix PPC crashBlue Swirl
Because of a typo, structure field vga_bios_size was not initialized properly and a bogus BAR6 for the nonexistent VGA BIOS appeared. The bug was uncovered by c169998802505c244b8bcad562633f29de7d74a4. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-11-12vnc: improve capslock handling.Gerd Hoffmann
When capslock is toggled while the vnc window hasn't the focus qemu will miss the state change. Add sanity checks for the capslock state and toggle it if needed, so hosts and guests idea of capslock state stay in sync. Simliar logic for numlock is present in qemu already.

2009-11-12e1000 fix: read access to some registers is missing.Kay Ackermann
While writing working on an e1000 driver for my university's OS I noticed that some registers aren't readable in QEMU, but they should be readable as stated in Intels Driver Developer Manual (and also verified on real hardware). Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-11-12virtio-blk: Pass read errors to the guestKevin Wolf

2009-11-12savevm: Delete existing snapshots in all imagesKevin Wolf
When creating a snapshot we can run into the situation that the first disk doesn't have a snapshot, but the second one does have one with the same name as the new snapshot. In this case, qemu doesn't recognize that there is a snapshot to be overwritten, so it starts to save the new snapshot and errors out later when it tries to snapshot the second image. With this patch, snapshots on secondary images are overwritten just like on the first image.

2009-11-12qdev: Check if unplug handler exists before calling itAmit Shah
A bus may have hotplugging enabled but not have the 'unplug' callback defined, which would lead to a crash on trying to unplug a device on the bus. Fix by introducing an assert to check if the callback is valid. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-12Makefile: Fix definition of pxe-*.bin blobsStefan Weil
* Remove 2nd entry for pxe-pcnet.bin. This kind of error can be avoided by sorting entries. So all pxe-*.bin entries are now sorted alphabetically. * Rename pxe-eepro100.bin -> pxe-i82559er.bin. This change completes another patch which did the rename on the pxe image for i82559er. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-12eepro100: Add missing .exit initialisationStefan Weil
Some devices did not have an initialisation value for entry ".exit". This is fixed here. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-11-12eepro100: Fix boot ROM supportStefan Weil
* Rename pxe-eepro100.bin to pxe-i82559er.bin. The other devices supported by eepro100.c need additional pxe boot ROM images. * Call rom_add_option during initialisation. The code won't work with two or more different eepro100 devices, because it only adds one option ROM, but this use case is perhaps never needed. Using this patch, model=i82559er at least works partially. For full support, more eepro100 patches are needed (will follow later, can be fetched from ar7 branch of QEMU).

2009-11-12serial: Add interface to set reference oscillator frequencyStefan Weil
Many (most?) serial interfaces have a programmable clock which provides the reference frequency ("baudbase"). So a fixed baudbase which is only set once can be wrong. omap1.c is an example which could use the new interface to change baudbase when the programmable clock changes. ar7 system emulation (still not part of standard QEMU) is similar to omap and already uses serial_set_frequency.

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.

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.

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.
