2012-01-21pseries: SLOF PCI flag dayBenjamin Herrenschmidt5-167/+104
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.

2012-01-21Correct types in bmdma_addr_{read,write}David Gibson1-2/+2
Back when I made patches introducing dma_addr_t and various PCI DMA wrapper functions, I made a mistake. The bmdma_addr_{read,write} functions need to take target_phys_addr_t not dma_addr_t, since they are assigned to MemoryRegionOps callbacks. This patch corrects my error.

2012-01-21Fix dirty logging with 32-bit qemu & 64-bit guestsBenjamin Herrenschmidt1-1/+2
The kvm_get_dirty_pages_log_range() function uses two address variables to step through the monitored memory region to update the dirty log. However, these variables have type unsigned long, which can overflow if running a 64-bit guest with a 32-bit qemu binary. This patch changes these to target_phys_addr_t which will have the correct size.

2012-01-21virtio: change memcpy to guest readsAlexander Graf1-6/+6
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 Herrenschmidt2-2/+40
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.

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: Default to 440EP CPUAlexander Graf1-1/+1
Today we're exposing a Virtex 440 CPU to the guest despite the fact that we're telling the guest that we're running on a 440EP one in the device tree. So let's better default to a real 440EP to make things synced again. Signed-off-by: Alexander Graf <agraf@suse.de>

2012-01-21PPC: 440: Ignore invalid PCI IRQsAlexander Graf1-0/+4
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 Graf1-1/+26
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 Graf1-6/+13
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>
