2012-01-27qdev: prepare source tree for code conversionAnthony Liguori
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. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-27qdev: add class_init to DeviceInfoAnthony Liguori
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 Liguori
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 Liguori
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 Liguori
This is a very shallow integration. We register a TYPE_DEVICE but only use QOM as basically a memory allocator. This will make all devices show up as QOM objects but they will all carry the TYPE_DEVICE. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> --- v1 -> v2 - update for new location of object.h

2012-01-26scsi: Guard against buflen exceeding req->cmd.xfer in scsi_disk_emulate_commandThomas Higdon
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 Graf
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 Herrenschmidt
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 Gibson
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 Herrenschmidt

2012-01-21virtio: change memcpy to guest readsAlexander Graf
When accessing the device specific virtio config space, we memcpy the data into a variable in QEMU. At that point we're basically pulling host endianness into the game which is a really bad idea. So instead, let's use the target specific load/store helpers for memory pointers which fetch things in target endianness. The whole array is already populated in target endianness anyways (see virtio-blk). Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-21virtio-pci: Fix endianness of virtio configBenjamin Herrenschmidt
The virtio config area in PIO space is a bit special. The initial header is little endian but the rest (device specific) is guest native endian. The PIO accessors for PCI on machines that don't have native IO ports assume that all PIO is little endian, which works fine for everything except the above. A complicated way to fix it would be to split the BAR into two memory regions with different endianess settings, but this isn't practical to do, besides, the PIO code doesn't honor region endianness anyway (I have a patch for that too but it isn't necessary at this stage). So I decided to go for the quick fix instead which consists of reverting the swap in virtio-pci in selected places, hoping that when we eventually do a "v2" of the virtio protocols, we sort that out once and for all using a fixed endian setting for everything.

2012-01-21PPC: Bamboo: fold ppc440.c and ppc440_bamboo.c into a single fileAlexander Graf
The separation of ppc440 and ppc440_bamboo makes some sense, since ppc440 is the SoC while ppc440_bamboo is the actual board. But the separation makes things harder for us for no good reason, so let's just fold them in together with each other. Signed-off-by: Alexander Graf <agraf@suse.de>

2012-01-21PPC: 440: Ignore invalid PCI IRQsAlexander Graf
When running a 440 target, we currently get invalid irq_num values (-1) which completely confuse the IRQ setting code. This is most likely due to the missing qdev conversion. While this shouldn't happen in the first place and should really rather be fixed by converting the target, I dislike segfaults. So for now, let's just print a warning and ignore invalid irq_num values. Signed-off-by: Alexander Graf <agraf@suse.de>
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.

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.
