3cc5d7a595 accel/amdxdna: Add carveout memory support for non-IOMMU systems
Add support for allocating buffers from reserved carveout memory when
IOMMU is not available. This is useful during debugging or bring-up.

In this configuration, the device uses physical addresses and does
not support scatter-gather lists, requiring physically contiguous
buffers.

Implement carveout-backed allocation and integrate it into buffer
management to support operation in physical address mode.

7455a0583a accel/ivpu: Add support for limiting NPU frequency
Add configurable frequency limits to allow users to constrain the NPU
operating frequency range for power and thermal management. This support
requires firmware API version 3.34.0 or newer.

New sysfs interface:

The freq/ subdirectory contains the following attributes:

- hw_min_freq: Minimum frequency supported by hardware (read-only)
- hw_max_freq: Maximum frequency supported by hardware (read-only)
- hw_efficient_freq: Hardware's optimal operating frequency (read-only)
- current_freq: Current NPU frequency in MHz (read-only)
- set_min_freq: Configure minimum operating frequency (50XX+ devices)
- set_max_freq: Configure maximum operating frequency (50XX+ devices)

Legacy attributes npu_max_frequency_mhz and npu_current_frequency_mhz
are maintained for backward compatibility.

Implementation details:

- Frequency configuration is communicated to firmware via JSM messages
- User-specified frequency values are clamped to hardware limits
- Power-efficient frequency (pn_ratio) is adjusted dynamically to stay
  within the configured range
- Frequency configuration is initialized during device boot
- The JSM API header is updated to version 3.34.0 to support the new
  VPU_JSM_MSG_FREQ_CONFIG firmware message

Added description for the sysfs attributes in the Documentation/ABI.

974d6764b7 accel/amdxdna: Set default DPM level based on QoS for temporal-only mode
The QoS request provided when creating a hardware context is currently
ignored when operating in temporal-only mode. Change this to use resource
allocation through xrs_allocate_resource(), which sets the default DPM
level according to the QoS request.

When multiple hardware contexts are active, track their required DPM
levels and set the default DPM level to the highest among them.

8711eb2dde accel/amdxdna: Improve tracing for job lifecycle and mailbox RX worker
Add more trace coverage to amdxdna job handling and mailbox receive
processing to make driver execution easier to debug.

Extend the xdna_job trace event to record the command opcode in
addition to the job sequence number. Use the enhanced tracepoint in
the job run, sent-to-device, signaled-fence, and job-free paths so
that trace output can be correlated with the command being executed.

Also add debug-point tracing when a command is received through the
submit ioctl path, and add a trace event when the mailbox RX worker
runs.

These changes improve visibility into job lifetime transitions and
mailbox activity, which helps debug command flow and scheduler issues.

d8c33b9c4b accel/amdxdna: Get device revision to derive VBNV string
Add support for querying the device revision from firmware.

Use the returned revision to look up the VBNV string during device
initialization, and fall back to the default VBNV when the revision
query is not supported or no mapping is found.

This allows the driver to report the accurate VBNV for devices that
share the same vendor/device ID but differ by hardware revision.

2d1e82f122 accel/amdxdna: Fix fatal_error_info layout in firmware interface
Adjust struct fatal_error_info to match the expected driver/firmware
interface layout.

The structure is used to retrieve debug information from firmware when
a command becomes stuck on the device. The reserved field currently
uses 128 u32 entries, which makes the structure larger than intended
and causes the layout to no longer match the firmware definition.

Reduce the reserved array size from 128 to 127 entries so the
structure matches the expected interface format.

c83ad8ea6b accel/amdxdna: Fix order of canceled mailbox messages
Mailbox message IDs are allocated cyclically. When destroying a mailbox
channel, pending messages are canceled starting from message ID 0. This
results in an incorrect cancellation order when the ID of the last posted
message wraps around and is smaller than the ID of the first posted
message.

9022f01097 accel/amdxdna: Check for device hang on job timeout
A job timeout does not necessarily indicate that the device is hung, as
it may still be processing other jobs.

Track whether any jobs have been successfully submitted or completed,
and use this information to determine if the device is making forward
progress. If so, return DRM_GPU_SCHED_STAT_NO_HANG instead of treating
the timeout as a device hang.

In the meanwhile the timeout interval is changed to 2 seconds which meets
the userspace requirement.

e0169d0c69 accel/amdxdna: Expose per-client BO memory usage via fdinfo
Implement amdxdna_show_fdinfo() to report per-client memory usage,
including below driver-specific memory stat:
  - heap allocation
  - internal BO allocation
  - external BO allocation

Hook the implementation into the DRM fdinfo infrastructure via
drm_driver.show_fdinfo, while continuing to expose standard DRM
memory stat through drm_show_memory_stats().

This improves observability of per-process memory usage and aligns
with existing fdinfo reporting mechanisms used by other drivers.

f844177c68 accel/amdxdna: Handle DETACH_DEBUG_BO through config_debug_bo path
Route DETACH_DEBUG_BO through aie2_config_debug_bo() the same way as
ATTACH_DEBUG_BO.

The scheduler switch in aie2_sched_job_run() already handles
ATTACH_DEBUG_BO with aie2_config_debug_bo(), but DETACH_DEBUG_BO was
not included in that path. Add an explicit fallthrough so both attach
and detach operations use the same handler.

This fixes debug BO detach handling by ensuring the detach command is

Update the amdxdna user-pointer (ubuf) BO path to support creating buffer

Detect read-only VMAs by checking VMA permissions across all user virtual
address ranges associated with the BO. When all entries are read-only, pin
user pages without FOLL_WRITE and export the resulting dmabuf as read-only
(O_RDONLY).

This allows userptr BOs backed by read-only mappings to be safely imported
and used without requiring write access, which was previously rejected due
to unconditional FOLL_WRITE usage.

2feec5ae5d accel/qaic: Handle DBC deactivation if the owner went away
When a DBC is released, the device sends a QAIC_TRANS_DEACTIVATE_FROM_DEV
transaction to the host over the QAIC_CONTROL MHI channel. QAIC handles
this by calling decode_deactivate() to release the resources allocated for
that DBC. Since that handling is done in the qaic_manage_ioctl() context,
if the user goes away before receiving and handling the deactivation, the
host will be out-of-sync with the DBCs available for use, and the DBC
resources will not be freed unless the device is removed. If another user
loads and requests to activate a network, then the device assigns the same
DBC to that network, QAIC will "indefinitely" wait for dbc->in_use = false,
leading the user process to hang.

As a solution to this, handle QAIC_TRANS_DEACTIVATE_FROM_DEV transactions
that are received after the user has gone away.

Track BO memory usage on a per-client basis by maintaining counters

reported statistics reflect the current memory footprint of each
process.

Wire the new query into the GET_ARRAY implementation to expose
the usage information to userspace.
