2020-09-29qapi/block.json: Add newline after "Example:" for block-latency-histogram-setPeter Maydell
The block-latency-histogram-set command is the only one which uses the Example/Examples section with the first line of the documentation immediately following the ':'. Bring it into line with the rest. This will allow us to avoid special-casing the indentation handling for "Examples" sections; instead for Examples as for any other section header these two indentations will be equivalent: Examples: Line one Line two Examples: Line one Line two Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-Id: <20200925162316.21205-3-peter.maydell@linaro.org> Reviewed-by: Markus Armbruster <armbru@redhat.com> [Commit message tweaked] Signed-off-by: Markus Armbruster <armbru@redhat.com>
2020-09-29qapi: Fix doc comment indentation againPeter Maydell
In commit 26ec4e53f2 and similar commits we fixed the indentation for doc comments in our qapi json files to follow a new stricter standard for indentation, which permits only: @arg: description line 1 description line 2 or: @arg: line 1 line 2 but because the script updates that enforce this are not yet in the tree we have had a steady trickle of subsequent changes which didn't follow the new rules. Fix the latest round of mis-indented doc comments.

2020-09-29tests/acpi: update golden master DSDT binary table blobs for q35Ani Sinha
In the previously applied commit ("piix4: don't reserve hw resources when hotplug is off globally"), we make changes to the ACPI DSDT tables such that some ACPI code are not generated when bsel is absent.

2020-09-29piix4: don't reserve hw resources when hotplug is off globallyAni Sinha
When acpi hotplug is turned off for both root pci bus as well as for pci bridges, we should not generate the related ACPI code for DSDT table or initialize related hw ports or reserve hw resources. This change makes sure all those operations are turned off in the case ACPI pci hotplug is off globally. In this change, we also make sure ACPI code for the PCNT method are only added when bsel is enabled for the corresponding pci bus or bridge hotplug is turned on. As q35 machines do not use bsel for it's pci buses at this point in time, this change affects DSDT acpi table for q35 machines as well. Therefore, we will also need to commit the updated golden master DSDT table acpi binary blobs as well. Following is the list of blobs which needs updating: tests/data/acpi/q35/DSDT tests/data/acpi/q35/DSDT.acpihmat tests/data/acpi/q35/DSDT.bridge tests/data/acpi/q35/DSDT.cphp tests/data/acpi/q35/DSDT.dimmpxm tests/data/acpi/q35/DSDT.ipmibt tests/data/acpi/q35/DSDT.memhp tests/data/acpi/q35/DSDT.mmio64 tests/data/acpi/q35/DSDT.numamem tests/data/acpi/q35/DSDT.tis These tables are updated in the following commit.

2020-09-29i440fx/acpi: do not add hotplug related amls for cold plugged bridgesAni Sinha
Cold plugged bridges are not hot unpluggable, even when their hotplug property (acpi-pci-hotplug-with-bridge-support) is turned off. Please see the function acpi_pcihp_pc_no_hotplug(). However, with the current implementaton, Windows would try to hot-unplug a pci bridge when it's hotplug switch is off. This is regardless of whether there are devices attached to the bridge. This is because we add ACPI code like _EJ0 etc for the pci slot where the bridge is cold plugged. In this fix, we identify a cold plugged bridge and for cold plugged bridges, we do not add the appropriate ACPI methods that are used by the OS to identify a hot-pluggable/unpluggable pci device. After this change, Windows does not detect the cold plugged pci bridge as ejectable. As a result of the patch, the following are the changes to the DSDT ACPI table: @@ -858,38 +858,33 @@ Return (Zero) } Method (_S2D, 0, NotSerialized) // _S2D: S2 Device State { Return (Zero) } Method (_S3D, 0, NotSerialized) // _S3D: S3 Device State { Return (Zero) } } Device (S18) { - Name (_SUN, 0x03) // _SUN: Slot User Number Name (_ADR, 0x00030000) // _ADR: Address - Method (_EJ0, 1, NotSerialized) // _EJx: Eject Device - { - PCEJ (BSEL, _SUN) - } } Device (S20) { Name (_SUN, 0x04) // _SUN: Slot User Number Name (_ADR, 0x00040000) // _ADR: Address Method (_EJ0, 1, NotSerialized) // _EJx: Eject Device { PCEJ (BSEL, _SUN) } } Device (S28) { Name (_SUN, 0x05) // _SUN: Slot User Number Name (_ADR, 0x00050000) // _ADR: Address @@ -1148,37 +1143,32 @@ PCEJ (BSEL, _SUN) } } Device (SF8) { Name (_SUN, 0x1F) // _SUN: Slot User Number Name (_ADR, 0x001F0000) // _ADR: Address Method (_EJ0, 1, NotSerialized) // _EJx: Eject Device { PCEJ (BSEL, _SUN) } } Method (DVNT, 2, NotSerialized) { - If ((Arg0 & 0x08)) - { - Notify (S18, Arg1) - } - If ((Arg0 & 0x10)) { Notify (S20, Arg1) } If ((Arg0 & 0x20)) { Notify (S28, Arg1) } If ((Arg0 & 0x40)) { Notify (S30, Arg1) } If ((Arg0 & 0x80)) While at it, I have also updated a stale comment.

2020-09-29Fix a gap where acpi_pcihp_find_hotplug_bus() returns a non-hotpluggable busAni Sinha
When ACPI hotplug for the root bus is disabled, the bsel property for that bus is not set. Please see the following commit: 3d7e78aa7777f ("Introduce a new flag for i440fx to disable PCI hotplug on the root bus"). As a result, when acpi_pcihp_find_hotplug_bus() is called with bsel set to 0, it may return the root bus. This can cause devices attached to the root bus to get hot-unplugged if the user issues the following set of commmands: outl 0xae10 0 outl 0xae08 your_slot Thanks to Julia for pointing this out here: https://www.mail-archive.com/qemu-devel@nongnu.org/msg734548.html In this patch, we fix the issue in this function by checking if the bus which is returned by the function is actually hotpluggable. If not, we simply return NULL. This avoids the scenario where we were returning a non-hotpluggable bus.

2020-09-29hw/smbios: report error if table size is too largeDaniel P. Berrangé
The SMBIOS 2.1 entry point uses a uint16 data type for reporting the total length of the tables. If the user passes -smbios configuration to QEMU that causes the table size to exceed this limit then various bad behaviours result, including - firmware hangs in an infinite loop - firmware triggers a KVM crash on bad memory access - firmware silently discards user's SMBIOS data replacing it with a generic data set. Limiting the size to 0xffff in QEMU avoids triggering most of these problems. There is a remaining bug in SeaBIOS which tries to prepend its own data for table 0, and does not check whether there is sufficient space before attempting this.

2020-09-29x68: acpi: trigger SMI before sending hotplug Notify event to OSPMIgor Mammedov
In case firmware has negotiated CPU hotplug SMI feature, generate AML to describe SMI IO port region and send SMI to firmware on each CPU hotplug SCI in case new CPUs were hotplugged. Since new CPUs can be hotplugged while CPU_SCAN_METHOD is running we can't send SMI before new CPUs are fetched from QEMU as it could cause sending Notify to a CPU that firmware hasn't seen yet. So fetch new CPUs into local cache first, then send SMI and after that send Notify events to cached CPUs. This should ensure that Notify is sent only to CPUs which were processed by firmware first. Any CPUs that were hotplugged after caching will be processed by the next CPU_SCAN_METHOD, when pending SCI is handled.
