2013-04-08hw: move target-independent files to subdirectoriesPaolo Bonzini1-1092/+0
This patch tackles all files that are compiled once, moving them to subdirectories of hw/. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-04-08hw: move headers to include/Paolo Bonzini1-1/+1
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

2013-03-15qdev: Implement (variable length) array propertiesPeter Maydell1-0/+104
Add support for declaring array properties for qdev devices. These work by defining an initial static property 'len-arrayname' which the user of the device should set to the desired size of the array. When this property is set, memory is allocated for the array elements, and dynamic properties "arrayname[0]", "arrayname[1]"... are created so the user of the device can then set the values of the individual array elements.

2013-03-01hw: include hw header files with full pathsPaolo Bonzini1-1/+1
Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.

2012-12-19qdev-properties.c: Separate core from the code used only by qemu-system-*Eduardo Habkost1-326/+1
This separates the qdev properties code in two parts: - qdev-properties.c, that contains most of the qdev properties code; - qdev-properties-system.c for code specific for qemu-system-*, containing: - Property types: drive, chr, netdev, vlan, that depend on code that won't be included on *-user - qemu_add_globals(), that depends on qemu-config.o. This change should help on two things: - Allowing DeviceState to be used by *-user without pulling dependencies that are specific for qemu-system-*; - Writing qdev unit tests without pulling too many dependencies. The copyright/license of qdev-properties.c isn't explicitly stated at the file, so add a simple copyright/license header pointing to the commit ID of the original file.

Move public headers to include/net, and leave private headers in net/. Put the virtio headers in include/net/tap.h, removing the multiple copies that existed. Leave include/net/tap.h as the interface for NICs, and net/tap_int.h as the interface for OS-specific parts of the tap backend. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-12-19janitor: do not rely on indirect inclusions of or from qemu-char.hPaolo Bonzini1-0/+1
Various header files rely on qemu-char.h including qemu-config.h or main-loop.h, but they really do not need qemu-char.h at all (particularly interesting is the case of the block layer!). Clean this up, and also add missing inclusions of qemu-char.h itself. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-11-15qdev: Split up header so it can be used in cpu.hAnthony Liguori1-0/+1
Header file dependency is a frickin' nightmare right now. cpu.h tends to get included in our 'include everything' header files but qdev also needs to include those headers mainly for qdev-properties since it knows about CharDriverState and friends. We can solve this for now by splitting out qdev.h along the same lines that we previously split the C file. Then cpu.h just needs to include qdev-core.h. hw/qdev.h is split into following new headers: hw/qdev-core.h hw/qdev-properties.h hw/qdev-monitor.h Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> [ehabkost: re-add DEFINE_PROP_PCI_HOST_DEVADDR, that was removed on the original patch (by mistake, I guess)] [ehabkost: kill qdev_prop_set_vlan() declaration] [ehabkost: moved get_fw_dev_path() comment to the original location (I don't know why it was moved)] [ehabkost: removed qdev_exists() declaration] [ehabkost: keep using 'QemuOpts' instead of 'struct QemuOpts', as qdev-core.h includes qemu-option.h] Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2012-08-01net: Rename VLANClientState to NetClientStateStefan Hajnoczi1-7/+7
The vlan feature is no longer part of net core. Rename VLANClientState to NetClientState because net clients are not explicitly associated with a vlan at all, instead they have a peer net client to which they are connected. This patch is a mechanical search-and-replace except for a few whitespace fixups where changing VLANClientState to NetClientState misaligned whitespace.

2012-07-17block: Geometry and translation hints are now useless, purge themMarkus Armbruster1-0/+1
There are two producers of these hints: drive_init() on behalf of -drive, and hd_geometry_guess(). The only consumer of the hint is hd_geometry_guess(). The callers of hd_geometry_guess() call it only when drive_init() didn't set the hints. Therefore, drive_init()'s hints are never used. Thus, hd_geometry_guess() only ever sees hints it produced itself in a prior call. Only the first call computes something, subsequent calls just repeat the first call's results. However, hd_geometry_guess() is never called more than once: the device models don't, and the block device is destroyed on unplug. Thus, dropping the repeat feature doesn't break anything now. If a block device wasn't destroyed on unplug and could be reused with a new device, then repeating old results would be wrong. Thus, dropping the repeat feature prevents future breakage. This renders the hints unused. Purge them from the block layer. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-06-18qdev: Move bus properties to abstract superclassesPaolo Bonzini1-18/+22
In qdev, each bus in practice identified an abstract superclass, but this was mostly hidden. In QOM, instead, these abstract classes are explicit so we can move bus properties there. All bus property walks are removed, and all device property walks are changed to look along the class hierarchy instead. We would have duplicates if class A defines some properties and its subclass B does not define any, because class_b->props will be left equal to class_a->props. The solution here is to reintroduce the class_base_init TypeInfo callback, that was present in one of the early QOM versions but removed (on my request...) before committing. This breaks global bus properties, an obscure feature when used with the command-line which is actually useful and used when used by backwards-compatible machine types. So this patch also adjusts the global bus properties in hw/pc_piix.c to refer to the abstract class. Globals and other properties must be modified in the same patch to avoid complications related to initialization ordering.

2012-06-08qdev: Use int32_t container for devfn propertyMichael Roth1-7/+4
Valid range for devfn is -1 to 255 (-1 for automatic assignment). We do not currently validate this due to devfn being stored as a uint32_t. This can lead to segfaults and other strange behavior. We could technically just cast it to int32_t to implement the checking, but this will not work for visitor-based setting where we may do additional bounds-checking based on target container type, which is int32_t for this case.

2012-04-05qdev: add blocksize property typeStefan Hajnoczi1-0/+46
Storage interfaces like virtio-blk can be configured with block size information so that the guest can take advantage of efficient I/O request sizes. According to the SCSI Block Commands (SBC) standard a device's block size is "almost always greater than one byte and may be a multiple of 512 bytes". QEMU currently has a 512 byte minimum block size because the block layer functions work at that granularity. Furthermore, the block size should be a power of 2 because QEMU calculates bitmasks from the value. Introduce a "blocksize" property type so devices can enforce these constraints on block size values. If the constraints are relaxed in the future then this property can be updated. Introduce the new PropertyValueNotPowerOf2 QError so QMP clients know exactly why a block size value was rejected.

2012-02-22qdev: accept hex properties only if prefixed by 0xPaolo Bonzini1-0/+12
Hex properties are an obstacle to removal of old qdev string parsing, but even here we can lay down the foundations for future simplification. In general, they are rarely used and their printed form is more interesting than the parsing. For example you'd usually set isa-serial.index instead of isa-serial.iobase. And luckily our main client, libvirt only cares about few of these, and always sets them with a 0x prefix. So the series stops accepting bare hexadecimal numbers, preparing for making legacy properties read-only in 1.3 or so. The read side will stay as long as "info qtree" is with us.
