2014-03-13raven: Move BIOS loading from board code to PCI hostHervé Poussineau1-0/+51
Raven datasheet explains where firmware lives in system memory, so do it there instead of in board code. Other boards using the same PCI host will not have to copy the firmware loading code.

2014-03-09pam: partly fix write-only modeHervé Poussineau1-1/+1
In write-only mode, writes are forwarded to RAM, while reads should not be handled (ie should return 0xff). Assume that in this mode, no read access is ever done, as they shouldn't give any sensible result. So, in write-only mode, alias PAM region to RAM, instead of PCI memory (which can even be mapped to some device!) This fixes Award BIOS, which use this mode to shadow system BIOS and video BIOS.

2013-12-23piix: fix 32bit pci holeGerd Hoffmann1-9/+2
Make the 32bit pci hole start at end of ram, so all possible address space is covered. We used to try and make addresses aligned so they are easier to cover with MTRRs, but since they are cosmetic on KVM, this is probably not worth worrying about. Of course the firmware can use less than that. Leaving space unused is no problem, mapping pci bars outside the hole causes problems though.

2013-12-23piix3 piix4: Clean up use of cannot_instantiate_with_device_add_yetMarkus Armbruster1-2/+10
A PIIX3/PIIX4 southbridge has multiple functions. We model each function as a separate qdev. Two of them need some special wiring set up in pc_init1() or mips_malta_init() to work: the ISA bridge at 01.0, and the SMBus controller at 01.3. The IDE controller at 01.1 (piix3-ide, piix3-ide-xen, piix4-ide) has always had cannot_instantiate_with_device_add_yet set, but there is no obvious reason why device_add could not work for them. Drop it. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Marcel Apfelbaum <marcel.a@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-12-23pci-host: Consistently set cannot_instantiate_with_device_add_yetMarkus Armbruster9-4/+66
Many PCI host bridges consist of a sysbus device and a PCI device. You need both for the thing to work. Arguably, these bridges should be modelled as a single, composite devices instead of pairs of seemingly independent devices you can only use together, but we're not there, yet. Since the sysbus part can't be instantiated with device_add, yet, permitting it with the PCI part is useless. We shouldn't offer useless options to the user, so let's set cannot_instantiate_with_device_add_yet for them. It's already set for Bonito, Grackle, i440FX and Raven. Document why. Set it for the others: dec-21154, e500-host-bridge, gt64120_pci, mch, pbm-pci, ppc4xx-host-bridge, sh_pci_host, u3-agp, uni-north-agp, uni-north-internal-pci, uni-north-pci, and versatile_pci_host.

2013-12-23sysbus: Set cannot_instantiate_with_device_add_yetMarkus Armbruster4-6/+0
device_add plugs devices into suitable bus. For "real" buses, that actually connects the device. For sysbus, the connections need to be made separately, and device_add can't do that. The device would be left unconnected, and could not possibly work. Quite a few, but not all sysbus devices already set cannot_instantiate_with_device_add_yet in their class init function. Set it in their abstract base's class init function sysbus_device_class_init(), and remove the now redundant assignments from device class init functions.

2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster4-10/+10
In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.

2013-12-20PPC: Use default pci bus name for grackle and heathrowAlexander Graf2-3/+3
There's no good reason to call our bus "pci" rather than let the default bus name take over ("pci.0"). The big downside to calling it different from anyone else is that tools that pass -device get confused. They are looking for a bus "pci.0" rather than "pci". To make life easier for everyone, let's just drop the name override. Signed-off-by: Alexander Graf <agraf@suse.de>

commit 398489018183d613306ab022653552247d93919f pc: limit 64 bit hole to 2G by default introduced a way for management to control the window allocated to the 64 bit PCI hole. This is useful, but existing management tools do not know how to set this property. As a result, e.g. specifying a large ivshmem device with size > 4G is broken by default. For example this configuration no longer works: -device ivshmem,size=4294967296,chardev=cfoo -chardev socket,path=/tmp/sock,id=cfoo,server,nowait Fix this by detecting that hole size was not specified and defaulting to the backwards-compatible value of 1 << 62.

2013-07-07pci: Replace pci_find_domain() with more general pci_root_bus_path()David Gibson2-0/+18
pci_find_domain() is used in a number of places where we want an id for a whole PCI domain (i.e. the subtree under a PCI root bus). The trouble is that many platforms may support multiple independent host bridges with no hardware supplied notion of domain number. This patch, therefore, replaces calls to pci_find_domain() with calls to a new pci_root_bus_path() returning a string. The new call is implemented in terms of a new callback in the host bridge class, so it can be defined in some way that's well defined for the platform. When no callback is available we fall back on the qbus name. Most current uses of pci_find_domain() are for error or informational messages, so the change in identifiers should be harmless. The exception is pci_get_dev_path(), whose results form part of migration streams. To maintain compatibility with old migration streams, the PIIX PCI host is altered to always supply "0000" for this path, which matches the old domain number (since the code didn't actually support domains other than 0). For the pseries (spapr) PCI bridge we use a different platform-unique identifier (pseries machines can routinely have dozens of PCI host bridges). Theoretically that breaks migration streams, but given that we don't yet have migration support for pseries, it doesn't matter. Any other machines that have working migration support including PCI devices will need to be updated to maintain migration stream compatibility.

2013-05-30q35: set fw_nameMichael S. Tsirkin1-0/+1
PCI host bridges need to set fw_name to be discoverable by bios for boot device selection. In particular, seabios expects root device to be called "/pci/@i0cf8", so let's set it up like that for Q35.
