2021-06-29hw/nvme: fix pin-based interrupt behavior (again)Klaus Jensen2-1/+18
Jakub noticed[1] that, when using pin-based interrupts, the device will unconditionally deasssert when any CQEs are acknowledged. However, the pin should not be deasserted if other completion queues still holds unacknowledged CQEs. The bug is an artifact of commit ca247d35098d ("hw/block/nvme: fix pin-based interrupt behavior") which fixed one bug but introduced another. This is the third time someone tries to fix pin-based interrupts (see commit 5e9aa92eb1a5 ("hw/block: Fix pin-based interrupt behaviour of NVMe"))... Third time's the charm, so fix it, again, by keeping track of how many CQs have unacknowledged CQEs and only deassert when all are cleared.

2021-06-29Partially revert "hw/block/nvme: drain namespaces on sq deletion"Klaus Jensen1-17/+2
This partially reverts commit 98f84f5a4eca5c03e32fff20f246d9b4b96d6422. Since all "multi aio" commands are now reimplemented to properly track the nested aiocbs, we can revert the "hack" that was introduced to make sure all requests we're properly drained upon sq deletion. The revert is partial since we keep the assert that no outstanding requests remain on the submission queue after the explicit cancellation.

2021-06-29hw/nvme: add param to control auto zone transitioning to zone state closedNiklas Cassel2-10/+23
In the Zoned Namespace Command Set Specification, chapter 2.5.1 Managing resources "The controller may transition zones in the ZSIO:Implicitly Opened state to the ZSC:Closed state for resource management purposes." The word may in this sentence means that automatically transitioning an implicitly opened zone to closed is completely optional. Add a new parameter so that the user can control if this automatic transitioning should be performed or not. Being able to control this can help with verifying that e.g. a user-space program behaves properly even without this optional ZNS feature. The default value is set to true, in order to not change the existing behavior.

2021-06-21hw/acpi: Provide function acpi_ghes_present()Peter Maydell2-0/+22
Allow code elsewhere in the system to check whether the ACPI GHES table is present, so it can determine whether it is OK to try to record an error by calling acpi_ghes_record_errors(). (We don't need to migrate the new 'present' field in AcpiGhesState, because it is set once at system initialization and doesn't change.)

Generic code in target/arm wants to call acpi_ghes_record_errors(); provide a stub version so that we don't fail to link when CONFIG_ACPI_APEI is not set. This requires us to add a new ghes-stub.c file to contain it and the meson.build mechanics to use it when appropriate.

2021-06-21s390x/css: Add passthrough IRBEric Farman3-1/+20
Wire in the subchannel callback for building the IRB ESW and ECW space for passthrough devices, and copy the hardware's ESW into the IRB we are building. If the hardware presented concurrent sense, then copy that sense data into the IRB's ECW space.

2021-06-21s390x/css: Refactor IRB constructionEric Farman3-16/+31
Currently, all subchannel types have "sense data" copied into the IRB.ECW space, and a couple flags enabled in the IRB.SCSW and IRB.ESW. But for passthrough (vfio-ccw) subchannels, this data isn't populated in the first place, so enabling those flags leads to unexpected behavior if the guest tries to process the sense data (zeros) in the IRB.ECW. Let's add a subchannel callback that builds these portions of the IRB, and move the existing code into a routine for those virtual subchannels. The passthrough subchannels will be able to piggy-back onto this later.

2021-06-21s390x/css: Introduce an ESW structEric Farman1-6/+13
The Interrupt Response Block is comprised of several other structures concatenated together, but only the 12-byte Subchannel-Status Word (SCSW) is defined as a proper struct. Everything else is a simple array of 32-bit words. Let's define a proper struct for the 20-byte Extended-Status Word (ESW) so that we can make good decisions about the sense data that would go into the ECW area for virtual vs passthrough devices.

2021-06-18vfio/migration: Correct device state from vmstate change for savevm caseKirti Wankhede1-1/+10
Set _SAVING flag for device state from vmstate change handler when it gets called from savevm. Currently State transition savevm/suspend is seen as: _RUNNING -> _STOP -> Stop-and-copy -> _STOP State transition savevm/suspend should be: _RUNNING -> Stop-and-copy -> _STOP State transition from _RUNNING to _STOP occurs from vfio_vmstate_change() where when vmstate changes from running to !running, _RUNNING flag is reset but at the same time when vfio_vmstate_change() is called for RUN_STATE_SAVE_VM, _SAVING bit should be set.
