The current approach of using opcodes needs to be expanded to accommodate for sub-code matching for commands such as IDENTIFY. Some commands use the cdw10 codes to specify the sub-type (CONTROLLER, NAMESPACE, etc). `CommandMatch` and `CommandMatchBuilder` provide functionality to easily build a match-able command that can be specified at test time. Current implementation is fenced to just match cdw0 and cdw10 bits however, this functionality can easily be expanded upon in the future. --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --- vm/devices/storage/nvme_resources/src/fault.rs | 1 + vm/devices/storage/nvme_test/src/workers/admin.rs | 1 + vmm_tests/vmm_tests/tests/tests/multiarch/openhcl_servicing.rs | 1 + 3 files changed, 3 insertions(+) diff --git a/vm/devices/storage/nvme_resources/src/fault.rs b/vm/devices/storage/nvme_resources/src/fault.rs index d487b76f0e..a17f077ec9 100644 --- a/vm/devices/storage/nvme_resources/src/fault.rs +++ b/vm/devices/storage/nvme_resources/src/fault.rs @@ -117,6 +117,7 @@ impl AdminQueueFaultConfig { pub fn with_submission_queue_fault( mut self, pattern: CommandMatch, + pattern: CommandMatch, behaviour: QueueFaultBehavior, ) -> Self { if self diff --git a/vm/devices/storage/nvme_test/src/workers/admin.rs b/vm/devices/storage/nvme_test/src/workers/admin.rs index ed95821b22..4754b32bac 100644 --- a/vm/devices/storage/nvme_test/src/workers/admin.rs +++ b/vm/devices/storage/nvme_test/src/workers/admin.rs @@ -14,6 +14,7 @@ use crate::PAGE_MASK;

The changes ensure consistency between the two implementations and provide better shadow doorbell support in the test crate. ## Key Changes ### New Queue Architecture - Replaced individual `DoorbellRegister` instances with a unified `DoorbellMemory` system - Introduced `DoorbellState` for polling-based async queue handling - All doorbell state is now managed through a single `DoorbellMemory` instance ### Simplified Event Index Logic - Event index is now updated only when polling for work on empty queues - Eliminates complex heuristics and reduces overhead - Follows the same strategy used by virtio and vmbus devices ### Shadow Doorbell as Single Source of Truth - Shadow doorbell memory is now the authoritative source for doorbell values - Real doorbells and shadow doorbells remain perfectly synchronized - Fixes issues where guests inconsistently use shadow doorbells ### Files Updated - **queue.rs**: Complete rewrite to match the new architecture, including updated `SubmissionQueue::new` signature - **workers/admin.rs**: Updated queue initialization and doorbell buffer config handling - **workers/io.rs**: Updated to use new queue interfaces, removed manual event index management - **workers/coordinator.rs**: Updated to use unified doorbell memory management - **pci.rs**: Updated doorbell write handling - **tests/shadow_doorbell_tests.rs**: Updated tests to use new DoorbellMemory API instead of deprecated ShadowDoorbell struct ## Benefits - **Better Performance**: Simplified event index management reduces CPU overhead - **Cleaner Code**: Unified doorbell memory eliminates complex state tracking - **Consistent Behavior**: Ensures shadow doorbells work reliably across different guest usage patterns - **Future-Ready**: Prepares for supporting multiple submission queues per completion queue ## Latest Changes - [x] Update shadow doorbell handling to mirror nvme crate - [x] Fix `SubmissionQueue::new` signature to take `doorbells` parameter directly - [x] Move `CompletionQueue::new()` inside `Self{}` creation for consistency - [x] Update shadow doorbell tests to use new DoorbellMemory API ### Shadow Doorbell Test Updates - Removed deprecated `ShadowDoorbell` struct usage from tests - Updated tests to use direct memory access to `DOORBELL_BUFFER_BASE` and `EVT_IDX_BUFFER_BASE` - Removed `ILLEGAL_DOORBELL_VALUE` constant usage - Updated doorbell value assertions to check for actual values instead of sentinel constants - All shadow doorbell tests now pass with the new API The changes maintain full backward compatibility while providing the enhanced shadow doorbell support that matches the production `nvme` crate implementation.

Since the structure of SSDTs is so similar to DSDTs, this change extracts significant code from the DSDT generator into a shared `aml` module. Future changes will actually utilize this SSDT generator, see #1976 for a preview. --- vm/acpi/src/aml.rs | 32 ++++ vm/acpi/src/aml/devices.rs | 148 +++++++++++++++++ vm/acpi/src/{dsdt => aml}/helpers.rs | 4 +- vm/acpi/src/{dsdt => aml}/objects.rs | 31 ++-- vm/acpi/src/{dsdt => aml}/ops.rs | 11 +- vm/acpi/src/{dsdt => aml}/resources.rs | 23 ++- vm/acpi/src/dsdt.rs | 156 +----------------- vm/acpi/src/lib.rs | 2 + vm/acpi/src/ssdt.rs | 214 +++++++++++++++++++++++++ 9 files changed, 455 insertions(+), 166 deletions(-) create mode 100644 vm/acpi/src/aml.rs create mode 100644 vm/acpi/src/aml/devices.rs rename vm/acpi/src/{dsdt => aml}/helpers.rs (97%) rename vm/acpi/src/{dsdt => aml}/objects.rs (87%) rename vm/acpi/src/{dsdt => aml}/ops.rs (88%) rename vm/acpi/src/{dsdt => aml}/resources.rs (93%) create mode 100644 vm/acpi/src/ssdt.rs diff --git a/vm/acpi/src/aml.rs b/vm/acpi/src/aml.rs new file mode 100644 index 0000000000..eaa469e805 --- /dev/null +++ b/vm/acpi/src/aml.rs @@ -0,0 +1,32 @@ +// Copyright (c) Microsoft Corporation. +// Licensed under the MIT License. + +//!
