2015-02-26acpi-build: simplify rsdp management for legacyMichael S. Tsirkin1-4/+6
For legacy machine types, rsdp is not in RAM, so we need a copy of rsdp for fw cfg. We previously used g_array_free with false parameter, but this seems to confuse people. This also wastes a bit of memory as the buffer is unused for new machine types. Let's just use plain g_memdup, and free original memory together with the array. TODO: rationalize tcpalog memory management, and get rid of the mfre parameter. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com>
2015-02-26acpi: has_immutable_rsdp->!rsdp_in_ramMichael S. Tsirkin3-7/+7
As comment in acpi-build.c notes, RSDP is not really immutable. So it's really a question of whether it's in RAM, name the variable accordingly. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com>
2015-02-26acpi-build: fix ACPI RAM managementMichael S. Tsirkin1-20/+23
This fixes multiple issues around ACPI RAM management: RSDP and linker RAM aren't currently marked dirty on update, so they won't be migrated correctly. Let's handle all tables in the same way: set correct size (assert if too big), update, mark RAM dirty. This also drops assert checking that table size didn't change: table size is fundamentally dynamic and depends on hw configuration, just set the correct size and use that (memory core asserts if size is too large). This also means we can drop tracking table size, memory core does this for us now. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2015-02-26pc: acpi-build: migrate RSDP tableIgor Mammedov3-9/+21
Makes sure that RSDP stays the same /i.e. matches ACPI tables blob in source/ if guest is migrated during RSDP reading or has been already shadowed by firmware. Fix applies only to new machine types starting from 2.3, so it won't break migration for old machine types. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.

2015-02-26pc: acpi-build: update linker on guest accessIgor Mammedov1-1/+7
Linker table is build only once, so if later during tables rebuild sizes of other ACPI tables change pointers will be patched incorrectly due to wrong offsets in linker. Resulting in guest not being able to find ACPI tables. Fix it by updating 'linker' table with the rest of tables when firmware reads it.

2015-02-26acpi: update RSDP on guest accessMichael S. Tsirkin1-6/+9
RSDT offset can change across reboots and that makes immutable RSDP, which is build at startup, point to incorrect place in ACPI table blob. That results in BIOS corrupting tables and guest OS failing to find ACPI tables. We really should have put it in a ROM region, but we can't change that for old machine types, let's just set the callback and update it explicitly. Signed-off-by: Michael S.

2015-02-26qdev: Don't exit when running into bad -globalMarkus Armbruster2-19/+10
-global lets you set a nice booby-trap for yourself: $ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l QEMU 2.1.94 monitor - type 'help' for more information (qemu) device_add usb-mouse Parameter 'usb_version' expects an int64 value or range $ echo $? 1 Not nice. Until commit 3196270 we even abort()ed. The same error triggers if you manage to screw up a machine type's compat_props. To demonstrate, change HW_COMPAT_2_1's entry to .driver = "usb-mouse",\ .property = "usb_version",\ .value = "1", \ Then run $ qemu-system-x86_64 -usb -M pc-i440fx-2.1 -device usb-mouse upstream-qemu: -device usb-mouse: Parameter 'usb_version' expects an int64 value or range $ echo $? 1 One of our creatively cruel error messages. Since this is actually a coding error, we *should* abort() here. Replace the error by an assertion failure in this case. But turn the fatal error into a mere warning when the faulty GlobalProperty comes from the user. Looks like this: $ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l QEMU 2.1.94 monitor - type 'help' for more information (qemu) device_add usb-mouse Warning: global usb-mouse.usb_version=l ignored (Parameter 'usb_version' expects an int64 value or range) (qemu) This is consistent with how we handle similarly unusable -global in qdev_prop_check_globals(). You could argue that the error should make device_add fail. Would be harder, because we're running within TypeInfo's instance_post_init() method device_post_init(), which can't fail.

Normalize to hmp_COMMAND(), where COMMAND is exactly the command name with '-' replaced by '_'. Exceptions: * do_device_add() and client_migrate_info() *not* renamed to hmp_device_add(), hmp_client_migrate_info(), because they're also QMP handlers. They still need to be converted to QAPI. * do_memory_dump(), do_physical_memory_dump(), do_ioport_read(), do_ioport_write() renamed do hmp_* instead of hmp_x(), hmp_xp(), hmp_i(), hmp_o(), because those names are too cryptic for my taste. * do_info_help() renamed to hmp_info_help() instead of hmp_info(), because it only covers help.

2015-02-18Make sysbus EHCI devices ARM only by defaultDavid Gibson1-1/+2
A number of ARM embedded boards include EHCI USB host controllers which appear as directly mapped devices, rather than sitting on a PCI bus. At present code to emulate such devices is included whenever EHCI support is included. This patch adjusts teh config options to only include them in builds targetting ARM by default.

2015-02-18PPC: Don't use legacy -usbdevice support for setting up boardMarkus Armbruster2-4/+10
It's tempting, because usbdevice_create() is so simple to use. But there's a lot of unwanted complexity behind the simple interface. Switch to usb_create_simple().

2015-02-18usb: Suppress bogus error when automatic usb-hub creation failsMarkus Armbruster1-7/+28
USBDevice's realize method usb_qdev_realize() automatically creates a usb-hub when only one port is left. Creating devices in realize methods is questionable, but works. If usb-hub creation fails, an error is reported to stderr, but the failure is otherwise ignored. We then create the actual device using the last port, which may well succeed. Example: $ qemu -nodefaults -S -display none -machine usb=on -monitor stdio QEMU 2.2.50 monitor - type 'help' for more information (qemu) device_add usb-mouse [Repeat 36 times] (qemu) info usb Device 0.0, Port 1, Speed 12 Mb/s, Product QEMU USB Mouse Device 0.0, Port 2, Speed 12 Mb/s, Product QEMU USB Hub Device 0.0, Port 2.1, Speed 12 Mb/s, Product QEMU USB Mouse [More mice and hubs omitted...] Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse (qemu) device_add usb-mouse usb hub chain too deep Failed to initialize USB device 'usb-hub' (qemu) info usb [...] Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse Device 0.0, Port 2.8.8.8.8.8, Speed 12 Mb/s, Product QEMU USB Mouse Despite the "Failed" message, the command actually succeeded. In QMP, it's worse. When adding the 37th mouse via QMP, the command fails with {"error": {"class": "GenericError", "desc": "usb hub chain too deep"}} Additionally, "Failed to initialize USB device 'usb-hub'" is reported on stderr. Despite the command failure, the device was created. This is wrong. Fix by avoiding qdev_init() for usb-hub creation, so we can ignore errors cleanly.

2015-02-18usb: Improve -usbdevice error reporting a bitMarkus Armbruster6-17/+19
Most LegacyUSBFactory usbdevice_init() methods realize with qdev_init_nofail(), even though their caller usbdevice_create() can handle failure. Okay if it really can't fail (I didn't check), but somewhat brittle. usb_msd_init() and usb_bt_init() call qdev_init(). The latter additionally reports an error when qdev_init() fails. Realization failure produces multiple error reports: a specific one from qdev_init(), and generic ones from usb_bt_init(), usb_create_simple(), usbdevice_create() and usb_parse(). Remove realization from the usbdevice_init() methods. Realize in usbdevice_create(), and produce exactly one error message there. You still get another one from usb_parse().
