2012-01-27qdev: prepare source tree for code conversionAnthony Liguori15-312/+304
These are various small stylistic changes which help make things more consistent such that the automated conversion script can be simpler. It's not necessary to agree or disagree with these style changes because all of this code is going to be rewritten by the patch monkey script anyway.

2012-01-27qdev: add class_init to DeviceInfoAnthony Liguori2-0/+9
Since we are still dynamically creating TypeInfo, we need to chain the class_init function in order to be able to make use of it within subclasses of TYPE_DEVICE. This will disappear once we register TypeInfos directly. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-27qdev: add a interface to register subclassesAnthony Liguori2-2/+8
In order to introduce inheritance while still using the qdev registration interfaces, we need to be able to use a parent other than TYPE_DEVICE. Add a new interface that allows this. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-01-27qdev: move qdev->info to classAnthony Liguori33-93/+119
Right now, DeviceInfo acts as the class for qdev. In order to switch to a proper ObjectClass derivative, we need to ween all of the callers off of interacting directly with the info pointer. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-27qdev: integrate with QEMU Object Model (v2)Anthony Liguori2-2/+35
This is a very shallow integration. We register a TYPE_DEVICE but only use QOM as basically a memory allocator.

2012-01-26scsi: Guard against buflen exceeding req->cmd.xfer in scsi_disk_emulate_commandThomas Higdon1-9/+1
Limit the return value (corresponding to the length of the buffer to be DMAed back to the intiator) to the value in req->cmd.xfer, which is the amount of data that the initiator expects. Eliminate now-duplicate code that does this guarding in the functions for individual commands. Without this, the SCRIPTS code in the emulated LSI device eventually raises a DMA interrupt for a data overrun when an INQUIRY command whose buflen exceeds req->cmd.xfer is processed. It's the responsibility of the client to provide a request buffer and allocation length that are large enough for the result of the command.

2012-01-21PPC: Pseries: Check for PCI boundariesAlexander Graf1-4/+23
We call pci_host_config_{read,write}_common() which perform PCI config accesses. However they don't do all limit checking the way we expect it to. So let's introduce a small wrapper around them, making them behave the way we would without touching generic code. This patch is based on a patch by David Gibson which put this logic into the generic code. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-01-21pseries: SLOF PCI flag dayBenjamin Herrenschmidt2-166/+103
Currently on the pseries machine the SLOF firmware is used normally, but we bypass it when -kernel is specified. Having these two different boot paths can cause some confusion. In particular at present we need to "probe" the (emulated) PCI bus and produce device tree nodes for the PCI devices in qemu, for the -kernel case. In the SLOF case, it takes the device tree from qemu adds some stuff to it then passes it on to the kernel. It's been decided that a better approach is to always boot through SLOF, even when using -kernel. WIth this approach we can leave PCI probing and device node creation to SLOF in all cases which removes a bunch of code in qemu, and avoids iterating the PCI devices from the machine specific init code which we're not supposed to do. This patch changes qemu to always boot through SLOF, and not to create PCI nodes. Simultaneously it updates the included version of SLOF (submodule and binary image) to one which supports (and requires) the new approach. The new SLOF version also includes a number of unrelated enhancements: support for booting from virtio-pci devices and e1000, greatly improved FCode support and many bugfixes. It also makes SLOF ready to be used even when specifying a kernel on the qemu command line.

2012-01-21pseries: Use correct dispatcher for PCI config space accessesDavid Gibson1-4/+4
The pseries machine expects a para-virtualized guest and so supplies RTAS functions (via a hypercall) for performing PCI config space access. Currently the implementation of these calls into pci_default_{read,write}_config(). However this would be incorrect for any PCI device which overrides the default config read/write functions. AFAICT there's only one such device today, but we should still get it right. In addition the pci_host_config_{read,write}_common() functions which do correctly do this dispatch, perform bounds checking on the config space address, lack of which currently leads to an exploitable bug. This patch corrects the problem. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2012-01-21pseries: Support PCI extended config space in RTAS callsBenjamin Herrenschmidt1-4/+10
On the pseries machine (which expexts a paravirtualized guest), guest access to PCI config space is via host-provided RTAS functions. This patch extends these RTAS functions to permit access to PCI extended config space, as specified in PAPR.
