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.

Please see the function acpi_pcihp_pc_no_hotplug() (thanks Julia). 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 amls like _EJ0 etc for the pci slot where the bridge is cold plugged. We have a demo video here: https://youtu.be/pME2sjyQweo In this fix, we identify a cold plugged bridge and for cold plugged bridges, we do not add the appropriate amls and acpi methods that are used by the OS to identify a hot-pluggable/unpluggable pci device. After this change, Windows does not show an option to eject the PCI bridge. A demo video is here: https://youtu.be/kbgej5B9Hgs 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.

It is used to unit test the flag 'acpi-pci-hotplug-with-bridge-support' used with pci bridges. This change also clears the file tests/qtest/bios-tables-test-allowed-diff.h so that future changes which affect the table can be caught. The following is the diff between files tests/data/acpi/pc/DSDT.bridge and tests/data/acpi/pc/DSDT.hpbridge after disassembly : @@ -1,30 +1,30 @@ /* * Intel ACPI Component Architecture * AML/ASL+

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 AMLs for the PCNT method are only added when bsel is enabled for the corresponding pci bus or bridge hotplug is turned on. As a result, when the hotplug for both the root pci device and bridge are disabled, this AML in the DSDT acpi table is turned off. 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 also commit the updated golden master DSDT table acpi binary blobs as well. Following is a typical diff between the q35 acpi DSDT table blobs: @@ -1,30 +1,30 @@ /* * Intel ACPI Component Architecture * AML/ASL+ Disassembler version 20180105 (64-bit version) * Copyright (c) 2000 - 2018 Intel Corporation * * Disassembling to symbolic ASL+ operators * - * Disassembly of tests/data/acpi/q35/DSDT, Tue Sep 15 18:52:47 2020 + * Disassembly of /tmp/aml-3O0DR0, Tue Sep 15 18:52:47 2020 * * Original Table Header: * Signature "DSDT" - * Length 0x00001DFE (7678) + * Length 0x00001DF6 (7670) * Revision 0x01 **** 32-bit table (V1), no 64-bit math support - * Checksum 0xAC + * Checksum 0x17 * OEM ID "BOCHS " * OEM Table ID "BXPCDSDT" * OEM Revision 0x00000001 (1) * Compiler ID "BXPC" * Compiler Version 0x00000001 (1) */ DefinitionBlock ("", "DSDT", 1, "BOCHS ", "BXPCDSDT", 0x00000001) { Scope (\) { OperationRegion (DBG, SystemIO, 0x0402, One) Field (DBG, ByteAcc, NoLock, Preserve) { DBGB, 8 } @@ -3113,24 +3113,20 @@ Name (_ADR, 0x00010000) // _ADR: Address Method (_S1D, 0, NotSerialized) // _S1D: S1 Device State { Return (Zero) } Method (_S2D, 0, NotSerialized) // _S2D: S2 Device State { Return (Zero) } Method (_S3D, 0, NotSerialized) // _S3D: S3 Device State { Return (Zero) } } - - Method (PCNT, 0, NotSerialized) - { - } } } } Signed-off-by: Ani Sinha --- hw/acpi/piix4.c | 6 ++++-- hw/i386/acpi-build.c | 23 +++++++++++++++++------ tests/data/acpi/q35/DSDT | Bin 7678 -> 7670 bytes tests/data/acpi/q35/DSDT.acpihmat | Bin 9002 -> 8994 bytes tests/data/acpi/q35/DSDT.bridge | Bin 7695 -> 7688 bytes tests/data/acpi/q35/DSDT.cphp | Bin 8141 -> 8133 bytes tests/data/acpi/q35/DSDT.dimmpxm | Bin 9331 -> 9323 bytes tests/data/acpi/q35/DSDT.ipmibt | Bin 7753 -> 7745 bytes tests/data/acpi/q35/DSDT.memhp | Bin 9037 -> 9029 bytes tests/data/acpi/q35/DSDT.mmio64 | Bin 8808 -> 8801 bytes tests/data/acpi/q35/DSDT.numamem | Bin 7684 -> 7676 bytes tests/data/acpi/q35/DSDT.tis | Bin 8283 -> 8276 bytes 12 files changed, 21 insertions(+), 8 deletions(-) changelog: v1: initial patch. v2: fixed a bug and added acpi DSDT table blobs for q35 to make unit tests pass. diff --git a/tests/data/acpi/q35/DSDT b/tests/data/acpi/q35/DSDT index bba8884073a27427b88ac0d733c9c87330a59366..4fad91b72e279b744b0528fd687c862d3a3d5cfa 100644 GIT binary patch delta 33 pcmexo{mq)oCDEHUxHPVoYElb9FB)33dtLkYiwAT)&ZPnJlLVYfOBwQ@nt~9^r>33dtLmt$aH^xnv|OqSE1H6}jTDPF*R@=jTQb`iD!XTJ~z0NaZSF#rGn diff --git a/tests/data/acpi/q35/DSDT.cphp b/tests/data/acpi/q35/DSDT.cphp index 57d859cef9fa16a8f125c4b338611c8472699f38..8d2395e3cb4383b30e3840caed0d09ccad0c7323 100644 GIT binary patch delta 33 ocmX?Wf7G7KCDY0kO^r)&Kwi delta 42 xcmX?Vf7YJMCDvmYDcpr+5K3mdPFRw(KHo0nUCQ3;+bB3f%wz diff --git a/tests/data/acpi/q35/DSDT.dimmpxm b/tests/data/acpi/q35/DSDT.dimmpxm index 9d5bd5744e2ba2e0f6126c3aba0bb36af865e499..df7422051c6feadeaa3b6733ad7efa67c339b49d 100644 GIT binary patch delta 33 ocmezD@!EsSCD)i9vcGQi_CDc=Kufz delta 42 xcmX@=cGiu{CD^ diff --git a/tests/data/acpi/q35/DSDT.mmio64 b/tests/data/acpi/q35/DSDT.mmio64 index efd3f1188f2b55da1514212d4be081a61c2a96e9..d8dd702b69cc24a6b58b8eaa79ea02439a2a7dd9 100644 GIT binary patch delta 33 ocmaFi^3a9LCD)i>_Ld&VC^b00^lI82|tP diff --git a/tests/data/acpi/q35/DSDT.numamem b/tests/data/acpi/q35/DSDT.numamem index 1978b55f1255402bf9bade0b91150b5cb49789a4..f36d22063a6eed4fb107ffd0e10477a2d6d7a983 100644 GIT binary patch delta 33 pcmZp%`D4xH66_N4N0xzs@!&?THL{#;EHUxHPVoYElMl$+0sy+k3XK2& delta 42 xcmexk-D1P#66_MfBFDhM7`l;bjVzZROH6#QQ@ns1%jEsCw(KHo0nUCQ3;^@W3X}i< diff --git a/tests/data/acpi/q35/DSDT.tis b/tests/data/acpi/q35/DSDT.tis index 638de3872673d17b1958497d0e62c83653de1602..203030a61a92c204bb93c43fe79e546471ae2985 100644 GIT binary patch delta 38 ucmccZaK(YkCDUZRU~-WC8&31`DbH delta 45 zcmccOaNB{)CDio_gpe);
