2015-07-13pc: fix reuse of pc-i440fx-2.4 in pc-i440fx-2.3Eduardo Habkost
commit fddd179ab962f6f78a8493742e1068d6a620e059, "pc: Convert *_MACHINE_OPTIONS macros into functions" broke the chaining of *_machine_options() functions on pc-i440fx-2.3, at: -#define PC_I440FX_2_3_MACHINE_OPTIONS \ - PC_I440FX_2_4_MACHINE_OPTIONS, \ - .alias = NULL, \ - .is_default = 0 +static void pc_i440fx_2_3_machine_options(QEMUMachine *m) +{ + pc_i440fx_machine_options(m); + m->alias = NULL; + m->is_default = 0; +} I have replaced PC_I440FX_2_4_MACHINE_OPTIONS with a pc_i440fx_machine_options() call, instead of calling pc_i440fx_2_4_machine_options(). This broke the setting of default_machine_opts and default_display on pc-i440fx-{2.0,2,1,2.2,2.3}. Fix this by making pc_i440fx_2_3_machine_options() reuse pc_i440fx_2_4_machine_options().

2015-07-08hw/i386/pc: don't carry FDC from pc_basic_device_init() to pc_cmos_init()Laszlo Ersek
Thanks to the last patch, pc_cmos_init() doesn't need the (optional) board-default FDC any longer as an input parameter. Update pc_basic_device_init() not to hand it back to pc_init1() / pc_q35_init(), and update the latter not to carry the FDC to pc_cmos_init(). This simplifies the code. pc_init1() | pc_q35_init() pc_basic_device_init() pc_cmos_init() Cc: Jan Tomko <jtomko@redhat.com> Cc: John Snow <jsnow@redhat.com> Cc: Markus Armbruster <armbru@redhat.com> Cc: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: John Snow <jsnow@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Michael S.

2015-07-08hw/i386/pc: reflect any FDC @ ioport 0x3f0 in the CMOSLaszlo Ersek
With the pc-q35-2.4 machine type, if the user creates an ISA FDC manually: -device isa-fdc,driveA=drive-fdc0-0-0 \ -drive file=...,if=none,id=drive-fdc0-0-0,format=raw then the board-default FDC will be skipped, and only the explicitly requested FDC will exist. qtree-wise, this is correct; however such an FDC is currently not registered in the CMOS, because that code is only reached for the board-default FDC. The pc_cmos_init_late() one-shot reset handler -- one-shot because the CMOS is not reprogrammed during warm reset -- should search for any ISA FDC devices, created implicitly (by board code) or explicitly, and set the CMOS accordingly to the ISA FDC(s) with iobase=0x3f0: - if there is no such FDC, report both drives absent, - if there is exactly one such FDC, report its drives in the CMOS, - if there are more than one such FDCs, then pick one (it is not specified which one), and print a warning about the ambiguity.

2015-07-07ich9: add TCO interface emulationPaulo Alcantara
This interface provides some registers within a 32-byte range and can be acessed through PCI-to-LPC bridge interface (PMBASE + 0x60). It's commonly used as a watchdog timer to detect system lockups through SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If NO_REBOOT bit is not set in GCS (General Control and Status register), the system will be resetted upon second timeout if TCO_RLD register wasn't previously written to prevent timeout. This patch adds support to TCO watchdog logic and few other features like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection, etc. are not implemented yet.

2015-06-11i386/acpi-build: fix PXB workarounds for unsupported BIOSesLaszlo Ersek
The patch apci: fix PXB behaviour if used with unsupported BIOS uses the following condition to see if a "PXB mem/IO chunk" has *not* been configured by the BIOS: (!range_base || range_base > range_limit) When this condition evaluates to true, said patch *omits* the corresponding entry from the _CRS. Later on the patch checks for the opposite condition (with the intent of *adding* entries to the _CRS if the "PXB mem/IO chunks" *have* been configured). Unfortunately, the condition was negated incorrectly: only the first ! operator was removed, which led to the nonsensical expression (range_base || range_base > range_limit) leading to bogus entries in the _CRS, and causing BSOD in Windows Server 2012 R2 when it runs on OVMF. The correct negative of the condition seen at the top is (range_base && range_base <= range_limit) Fix the expressions. Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Michael S.

2015-06-11i386/acpi-build: more traditional _UID and _HID for PXB root busesLaszlo Ersek
The ACPI specification permits the _HID and _UID objects to evaluate to strings. (See "6.1.5 _HID (Hardware ID)" and "6.1.12 _UID (Unique ID)" in the ACPI v6.0 spec.) With regard to related standards, the UEFI specification can also express a device address composed from string _HID and _UID identifiers, inside the Expanded ACPI Device Path Node. (See "9.3.3 ACPI Device Path", Table 49, in the UEFI v2.5 spec.) However, numeric (integer) contents for both _HID and _UID are more traditional. They are recommended by the UEFI spec for size reasons: [...] the ACPI Device Path node is smaller and should be used if possible to reduce the size of device paths that may potentially be stored in nonvolatile storage [...] External tools support them better (for example the --acpi_hid and --acpi_uid options of "efibootmgr" only take numeric identifiers). Finally, numeric _HID and _UID contents are existing practice in the QEMU source. This patch was tested with a Fedora 20 LiveCD and a preexistent Windows Server 2012 R2 guest. Using "acpidump" and "iasl" in the Fedora guest, we get, in the SSDT: > Scope (\_SB) > { > Device (PC04) > { > Name (_UID, 0x04) // _UID: Unique ID > Name (_HID, EisaId ("PNP0A03") /* PCI Bus */) // _HID: Hardware ID Cc: Marcel Apfelbaum <marcel@redhat.com> Cc: Michael S.

2015-06-04hw/acpi: piix4_pm_init(): take fw_cfg object no moreLaszlo Ersek
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.

2015-06-02pc: Ensure non-zero CPU ref count after attaching to ICC busAndreas Färber
Setting the parent bus of a device increases its ref count, which we ultimately want to level out. However it is only safe to do so after the last reference to the device in local code, as qom-set or similar operations might decrease the ref count. Therefore move the object_unref() from pc_new_cpu() into its callers. The APIC operations on the last CPU in pc_cpus_init() are still potentially insecure, but that is beyond the scope of this code movement.

2015-05-31i386/pc_q35: don't insist on board FDC if there's no default floppyLaszlo Ersek
The "no_floppy = 1" machine class setting causes "default_floppy" in main() to become zero. Consequently, default_drive() will not call drive_add() and drive_new() for IF_FLOPPY, index=0, meaning that no default floppy drive will be created for the virtual machine. In that case, board code should also not insist on the creation of the board-default FDC. The board-default FDC will still be created if the user requests a floppy drive with "-drive if=floppy". Additionally, separate FDCs can be specified manually with "-device isa-fdc". They allow the -device isa-fdc,driveA=... syntax that is more flexible than the one required by the board-default FDC: -global isa-fdc.driveA=... This patch doesn't change the behavior observably, as all Q35 machine types have "no_floppy = 0".

2015-05-31i386/pc: pc_basic_device_init(): delegate FDC creation requestLaszlo Ersek
This patch introduces no observable change, but it allows the callers of pc_basic_device_init(), ie. pc_init1() and pc_q35_init(), to request (or not request) the creation of the FDC explicitly. At the moment both callers pass constant create_fdctrl=true (hence no observable change). Assuming a board passes create_fdctrl=false, "floppy" will be NULL on output, and (beyond the FDC not being created) that NULL will be passed on to pc_cmos_init(). Luckily, pc_cmos_init() already handles that case.

2015-05-31pc: acpi: fix pvpanic for buggy guestsRadim Krčmář
In the old times, we always had pvpanic in ACPI and a _STA method told the guest not to use it. Automatic generation dropped the _STA method as the specification says that missing _STA means enabled and working. Some guests (Linux) had buggy drivers and this change made them unable to utilize pvpanic. A Linux patch is posted as well, but I think it's worth to make pvpanic useable on old guests at the price of three lines and few bytes of SSDT. The old _STA method was Method (_STA, 0, NotSerialized) { Store (PEST, Local0) If (LEqual (Local0, Zero)) { Return (Zero) } Else { Return (0x0F) }} Igor pointed out that we don't need to use a method to return a constant and that 0xB (don't show in UI) is the common definition now.
