* pc: use new CPU hotplug interface since 2.7 machine typeIgor Mammedov2016-06-241-0/+32
| | | | | | | | | | | | | | | | | | For compatibility reasons PC/Q35 will start with legacy CPU hotplug interface by default but with new CPU hotplug AML code since 2.7 machine type. That way legacy firmware that doesn't use QEMU generated ACPI tables will be able to continue using legacy CPU hotplug interface. While new machine type, with firmware supporting QEMU provided ACPI tables, will generate new CPU hotplug AML, which will switch to new CPU hotplug interface when guest OS executes its _INI method on ACPI tables loading.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little.

| | | | | | | | | | | | | | These commands are handled entirely by QEMU. Do not raise an SMI when they happen, because Windows (at least 2008r2) expects these commands to work and (depending on the value of APMC_EN at startup) the firmware might not have installed an SMI handler. When this happens (e.g. the kernel supports SMIs, or you are using TCG, but you have used "-machine smm=off") RIP is moved to 0x38000 where there is no code to execute. Acked-by: Michael S.

* hw/acpi: piix4_pm_init(): take fw_cfg object no moreLaszlo Ersek2015-06-041-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | This PIIX4 init function has no more reason to receive a pointer to the FwCfg object. Remove the parameter from the prototype, and update callers. As a result, the pc_init1() function no longer needs to save the return value of pc_memory_init() and xen_load_linux(), which makes it more similar to pc_q35_init(). The return type & value of pc_memory_init() and xen_load_linux() are not changed themselves; maybe we'll need their return values sometime later.

* hw/acpi: move "etc/system-states" fw_cfg file from PIIX4 to coreLaszlo Ersek2015-06-041-8/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | The acpi_pm1_cnt_init() core function is responsible for setting up the register block that will ultimately react to S3 and S4 requests (see acpi_pm1_cnt_write()). It makes sense to advertise this configuration to the guest firmware via an easy to parse fw_cfg file (ACPI is too complex for firmware to parse), and indeed PIIX4 does that. However, since acpi_pm1_cnt_init() is not specific to PIIX4, neither should be the fw_cfg file. This patch makes "etc/system-states" appear on all chipsets modified in the previous patch, not just PIIX4 (assuming they have fw_cfg at all).

|/ | | | | | | | | | | | | | | | | | due to recent change introduced by: "pcihp: reduce number of device check events" 'up' field is cleared right after it's read. This is incompatible with legacy BIOS ACPI code where PCNF ACPI method reads this field 32 times. To make pci_read mmio callback compatible with legacy 'up' behavior, pcihp code will need to know in which mode it runs add 'legacy_piix' field to AcpiPciHpState structure and alter register behavior accordingly.

| | | | | | | | | | | | | | | | | | | | | | | | Hardcoded GPE0 mask isn't really needed. Since GPE0_STS initialized with all bits cleared and only QEMU itself can set bits there (i.e. guest can only clear bits in it). So guest can't triger SCI by setting _STS & _EN bits and there is not reason to mask out not supported _STS bits since they shouldn't be set by QEMU in the first place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster2013-12-231-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
