2012-01-21PPC: Bamboo: Set initial TLB entryAlexander Graf
Back in the day when the bamboo target got introduced, the initial TLB was dictated by KVM. TCG has been missing initial TLB values ever since, rendering the target unusable for TCG usage. This patch adds linear TLB maps the way Linux expects them, making the target work. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-01-21PPC: Bamboo: Register CPU resetAlexander Graf
To be able to support CPU reset, we need to put all register initialization and initial state into a CPU reset hook instead of a function that is only called once on bootup. This is a preparation step for the initial TLB setting code and brings bamboo more in line with what e500 and virtex already do. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-01-21PPC: 440EP: Initialize timerAlexander Graf
When using TCG with a BookE PowerPC core, we need to explicitly initialize the BookE timers with the correct frequencies. This was missing for 440EP, since that code came from KVM and was never used with TCG. Signed-off-by: Alexander Graf <agraf@suse.de>

2012-01-17arm: make the number of GIC interrupts configurableMark Langsdorf
Increase the maximum number of GIC interrupts for a9mp and a11mp to 1020, and create a configurable property for each defaulting to 96 and 64 (respectively) so that device modelers can set the value appropriately for their SoC. Other ARM processors also set their maximum number of used IRQs appropriately. Set the maximum theoretical number of GIC interrupts to 1020 and update the save/restore code to only use the appropriate number for each SoC.

2012-01-17xhci: Initial xHCI implementationHector Martin
Based on the implementation from Hector Martin <hector@marcansoft.com> Hectors's implementation completely sidestepped the qemu usb system and used libusb directly for usb device pass through. So I've ripped out the libusb bits (or left them in disabled, as reference for further coding) and hooked up the qemu subsystem instead. That work is not complete yet though, partly due to limitations of the qemu usb subsystem. Nevertheless I think it is better to continue development in-tree, especially as the qemu usb bits need a bunch of improvements too for decent usb 3.0 support. Current state: - usb-storage emulation should work ok. - Devices which need constant polling (HID emulation like usb-tablet) are known to not work. - ISO xfers are not implemented yet. - superspeed ports are not implemented yet. - usb pass-through is completely untested so far.

2012-01-13virtio-blk: refuse SG_IO requests with scsi=offPaolo Bonzini
QEMU does have a "scsi" option (to be used like -device virtio-blk-pci,drive=foo,scsi=off). However, it only masks the feature bit, and does not reject the command if a malicious guest disregards the feature bits and issues a request. Without this patch, using scsi=off does not protect you from CVE-2011-4127.

Coverity complained about local variable key which was only partially initiated. Only key.st_value was set. As this was also the only part of key which was used in function symfind, the code could be optimized by directly passing a pointer to orig_addr. In bsd-user/elfload.c, fix ec822001a2f26eef8701194714f6482b6d852de2 was missing. This was a simple replacement of > by >= in symfind, so I fixed it here without creating an additional patch.
