2012-01-17usb: add USBEndpointGerd Hoffmann3-0/+45
Start maintaining endpoint state at USBDevice level. Add USBEndpoint struct and some helper functions to deal with it. For now it contains the endpoint type only. Moved over some bits from usb-linux.c Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-01-17xhci: Initial xHCI implementationHector Martin2-0/+2752
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.

2012-01-17hw/arm_boot.c: Make SMP boards specify address to poll in bootup loopEvgeny Voevodin4-8/+15
The secondary CPU bootloader in arm_boot.c holds secondary CPUs in a pen until the primary CPU releases them. Make boards specify the address to be polled to determine whether to leave the pen (it was previously hardcoded to 0x10000030, which is a Versatile Express/ Realview specific system register address).

2012-01-13virtio-console: no need to remove char handlers explicitlyAmit Shah1-17/+0
qdev is now equipped (thanks to the last commit) to disassociate chardevs from the qdev devices on the devices going away. So doing it in the virtio-console driver is not necessary. Since that was the only thing being done in the qdev exit method, drop it entirely. Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-13qdev: Add a 'free' method to disassociate chardev from qdev deviceAmit Shah1-0/+11

2012-01-13virtio-blk: refuse SG_IO requests with scsi=offPaolo Bonzini1-0/+6
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.

This brings a usb audio device to qemu. Output only, fixed at 16bit stereo @ 480000 Hz. Based on a patch from H.

2012-01-10elf: Improve symbol lookup (optimize, fix for bsd-user)Stefan Weil1-7/+5
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.

2012-01-07malta: Fix regression (i8259 interrupts did not work)Stefan Weil1-4/+35
Commit 5632ae46d5bda798e971dae48ebb318ac2c3686a passes the address of i8259 to qemu_irq_proxy. i8259 is an auto variable with undefined value outside of mips_malta_init. This made the interrupt proxy unusable: either QEMU crashes, or the interrupt handler was not called. Ethernet for example no longer worked with MIPS Malta. v2: While v1 used a static variable for i8259, this patch introduces a qdev for the malta machine. i8259 is now part of the device status. This is a minimal qdev implementation to keep the patch small. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

Replace error_report("DEVICE-NAME: MESSAGE"); by just error_report("MESSAGE"); in block device init functions. DEVICE-NAME is bogus in some cases: it's "scsi-disk" for device scsi-hd and scsi-cd, "virtio-blk-pci" for virtio-blk-s390, and "usb-msd" for usb-storage. There is no real need to put a device name in the message, because error_report() points to the offending command line option already: $ qemu-system-x86_64 --nodefaults --enable-kvm -vnc :0 -S -monitor stdio -usb -device virtio-blk-pci upstream-qemu: -device virtio-blk-pci: virtio-blk-pci: drive property not set upstream-qemu: -device virtio-blk-pci: Device 'virtio-blk-pci' could not be initialized And for a monitor command, it's obvious anyway: $ qemu-system-x86_64 --nodefaults --enable-kvm -vnc :0 -S -monitor stdio -usb (qemu) device_add virtio-blk-pci virtio-blk-pci: drive property not set Device 'virtio-blk-pci' could not be initialized Reported-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
