2009-12-16s390: Fix buggy assignmentStefan Weil
nd->model keeps dynamically allocated model names. So casting of a constant string is wrong here. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Acked-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-13target-alpha: Implement RD/WRUNIQUE in the translatorRichard Henderson
When emulating user-mode only, there's no reason to exit the translation block to effect a call_pal. We can generate a move to/from the unique slot directly. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-13workaround for cmd646 bmdma register access while no dma is activeIgor V. Kovalenko
This is a workaround only, and is a partial revert of a few changes to BMDMAState which removed pci_dev field on the way. - cmd646 pci_from_bm() expects bm->unit value to correspond with bm data being passed to callback as opaque pointer. This breaks when write to dma control register of second channel happens when no dma operation is in progress, so bm->unit is zero for second channel, and pci_from_bm() returns garbage pointer. Crash happens shortly after that while dereferencing that pointer. v0->v1: cleaned up dead code from pci_from_bm. Signed-off-by: Igor V.

2009-12-13fdc/sparc32: don't hang on detection under OBPArtyom Tarasenko
Stepping through the SS-5's OBP initialization routines it looks like reading fdc main status register should clear the fd interrupt. The patch doesn't fix problems with fdc on sparc platform, it only fixes fdc detection. Signed-off-by: Artyom Tarasenko <atar4qemu@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-12-13Sparc32: implement AFX for SS-5Artyom Tarasenko
Implement a stub for the AFX register on SparcStation-5. This stub is needed for running the original SS-5 OBP instead of OpenBIOS (which allows to boot Solaris 2.5.1 and Solaris 2.6 kernels). Signed-off-by: Artyom Tarasenko <atar4qemu@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-12-13scsi-disk: Inquiry with allocation length of CDB < 36 (v4)Artyom Tarasenko
According to the SCSI-2 specification, http://ldkelley.com/SCSI2/SCSI2/SCSI2/SCSI2-08.html#8.2.5 , "if the allocation length of the command descriptor block (CDB) is too small to transfer all of the parameters, the additional length shall not be adjusted to reflect the truncation." The 36 mandatory bytes of response are written to outbuf, and then only the length requested in CDB is transferred.

2009-12-12PCI: Convert pci_device_hot_add() to QObjectLuiz Capitulino
Return a QDict with information about the just added device. This commit should not change user output. Please, note that this patch does not do error handling conversion. In error conditions the handler still calls monitor_printf(). Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-12scsi: fix drive hotplug.Gerd Hoffmann
This patch fills the DriveInfo->unit after hotplugging a scsi disk. It makes a difference when auto-assigning a scsi id, where unit was left filled with '-1' instead of the actual scsi id. With this patch applied the the drive naming logic in drive_init() works as good as it did in previous releases. Which means it works fine with a single scsi bus.

2009-12-12pci: don't hw_error() when no slot is available.Gerd Hoffmann
Current PCI code will simply hw_error() and thus abort in case no free PCI slot is available or the requested PCI slot is already in use by another device. For the hotplug case this behavior is not acceptable. This patch makes qemu pass up the error properly, so the calling code can decide whenever it wants to exit with an error (on startup) or whenever it wants to continue (hotplug).

2009-12-12pci: don't abort() when trying to hotplug with acpi off.Gerd Hoffmann
The PCI bus on x86 requires ACPI for hotplug support, thus disbling ACPI also disables hotplug for the PCI bus. This patch makes qemu check whenever the PCI bus in question can handle hotplug before trying to add devices. This is needed because qdev will abort() on any attempt to hotplug devices into a non-hotpluggable bus.

2009-12-12Set default console to virtio on S390xGerd Hoffmann
All "normal" system emulation targets in qemu I'm aware of display output on either VGA or serial output. Our S390x virtio machine doesn't have such kind of legacy hardware. So instead we need to default to a virtio console. Add flags to QEMUMachine to indicate which kind of default devices make sense for the machine in question. Use it for S390x: enable virtcon, disable serial, parallel and vga. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-12qdev: also match bus name for global propertiesGerd Hoffmann

2009-12-12qdev: make compat stuff more genericGerd Hoffmann

2009-12-12qdev: Replace device names containing whitespaceMarkus Armbruster
Device names with whitespace require quoting in the shell and in the monitor. Some of the offenders are also overly long. Some have a more convenient alias, some don't. The place for verbose device names is DeviceInfo member desc. The name should be short & sweet.

2009-12-12qdev: Separate USB product description from qdev nameMarkus Armbruster
Using the qdev name for the product description makes for inconvenient qdev names. Put the product description in new USBDeviceInfo member product_desc. Make usb_qdev_init() use it. No user or guest visible change, since the value is still the same. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-12qdev: Rename USBDevice member devname to product_descMarkus Armbruster

2009-12-12fix rtc-td-hack on host without high-res timersGleb Natapov
On hosts without high-res timers it is impossible to inject rtc interrupt faster then 1kHz. Windows sometimes configures RTC to generate 1kHz interrupts, so we can't inject missed interrupts when running on such hosts. Always injecting an interrupt on REG_C read is also not an option since Windows wait for REG_C to become zero with interrupt disabled during boot. This patch uses mixed approach: accelerate timer + inject up to 1000 interrupts on REG_C read. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

On S390x we don't want to go through the hassle of emulating real existing hardware, because we don't need to for running Linux.
