2012-01-03xen: convert to MemoryListener APIAvi Kivity
Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-20memory: temporarily add memory_region_get_ram_addr()Avi Kivity
This is a layering violation, but needed while the code contains naked calls to qemu_get_ram_ptr() and the like. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-20xen, vga: add API for registering the framebufferAvi Kivity
Xen currently uses the name of a memory region to determine whether it is the framebuffer. Replace with an explicit API. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-20vhost: convert to MemoryListener APIAvi Kivity
Drop the use of cpu_register_phys_memory_client() in favour of the new MemoryListener API. The new API simplifies the caller, since there is no need to deal with splitting and merging slots; however this is not exploited in this patch. Signed-off-by: Avi Kivity <avi@redhat.com>

2011-12-20kvm: switch kvm slots to use host virtual address instead of ram_addr_tAvi Kivity
This simplifies a later switch to the memory API in slot management. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-20memory: add API for observing updates to the physical memory mapAvi Kivity
Add an API that allows a client to observe changes in the global memory map: - region added (possibly with logging enabled) - region removed (possibly with logging enabled) - logging started on a region - logging stopped on a region - global logging started - global logging removed This API will eventually replace cpu_register_physical_memory_client().

2011-12-20memory: replace cpu_physical_sync_dirty_bitmap() with a memory APIAvi Kivity
The function is still used as the implementation. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-20framebuffer: drop use of cpu_physical_sync_dirty_bitmap()Avi Kivity
Replace with memory API equivalent. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-20loader: remove calls to cpu_get_physical_page_desc()Avi Kivity
cpu_get_physical_page_desc() is tied into the memory core's innards, replace it with uses of the API. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-20framebuffer: drop use of cpu_get_physical_page_desc()Avi Kivity
cpu_get_physical_page_desc() is tied into the memory core's innards, replace it with uses of the API. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-20memory: introduce memory_region_find()Avi Kivity
Given an address space (represented by the top-level memory region), returns the memory region that maps a given range. Useful for implementing DMA. The implementation is a simplistic binary search. Once we have a tree representation this can be optimized. Signed-off-by: Avi Kivity <avi@redhat.com>

2011-12-20sysbus: add sysbus_address_space()Avi Kivity
Given a bus device, retrieves the memory address space for its bus. Signed-off-by: Avi Kivity <avi@redhat.com>
2011-12-19sysbus: remove sysbus_init_mmio_cb2Benoît Canet
This function is not longer in use so remove it. Signed-off-by: Benoît Canet <benoit.canet@gmail.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-19ppce500_pci: remove sysbus_init_mmio_cb2 usageBenoît Canet

2011-12-19sh_pci: remove sysbus_init_mmio_cb2 usageBenoît Canet
The isa region is not exposed as a sysbus region because the iobr register contains its address and use it to remap dynamically the region.

2011-12-19qom: register qdev properties also as non-legacy propertiesPaolo Bonzini
Push legacy properties into a "legacy-..." namespace, and make them available with correct types too. For now, all properties come in both variants. This need not be the case for string properties. We will revisit this after -device is changed to actually use the legacy properties.

2011-12-19qom: introduce get/set methods for PropertyPaolo Bonzini
This patch adds a visitor interface to Property. This way, QOM will be able to expose Properties that access a fixed field in a struct without exposing also the everything-is-a-string "feature" of qdev properties. Whenever the printed representation in both QOM and qdev (which is typically the case for device backends), parse/print code can be reused via get_generic/set_generic. Dually, whenever multiple PropertyInfos have the same representation in both the struct and the visitors the code can be reused (for example among all of int32/uint32/hex32).

2011-12-19qom: push permission checks up into qdev_property_add_legacyPaolo Bonzini
qdev_property_get and qdev_property_set can generate permission denied errors themselves. Do not duplicate this functionality in qdev_get/set_legacy_property, and clean up excessive indentation.

2011-12-19qapi: protect against NULL QObject in qmp_input_get_objectPaolo Bonzini
A NULL qobj can occur when a parameter is fetched via qdict_get, but the parameter is not in the command. By returning NULL, the caller can choose whether to raise a missing parameter error, an invalid parameter type error, or use a default value. For example, qom-set could can use this to reset a property to its default value, though at this time it will fail with "Invalid parameter type". In any case, anything is better than crashing!

2011-12-19vl.c: In qemu -h output, only print options for the arch we are running asMichael Ellerman
Only print options in the help output that are accepted by our arch. This is less confusing for users and also for other programs that consume the help output. The options affected are: -g and -prom-env only displayed on PPC or SPARC -win2k-hack, -rtc-td-hack, -no-fd-bootchk, -no-acpi, -no-hpet, -acpitable, -smbios only displayed on i386 -semihosting only displayed on ARM, M68K or XTENSA -old-param only displayed on ARM Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-12-19vl.c: Move option generation logic into a wrapper fileMichael Ellerman
In vl.c and qemu-options.h we define macros and include qemu-options.def in order to generate different content. Move the bulk of the def'ing and undef'ing into a wrapper, this will make it cleaner when we add another macro in the next patch. AFAICS undefining GEN_DOCS services no purpose, but I've left it for now. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-12-19configure: Improve Xen autodetection for hosts without XenStefan Weil
With this patch, it only takes one test (instead of four) to detect that there is no Xen support at all. For most build hosts, this will reduce the time configure needs. It will also reduce noisy output in config.log. Build hosts with Xen now need up to five (instead of up to four) tests. They get improved diagnostics when Xen support fails.
