accel/amdxdna: Support preemption requests

2025-11-05T16:56:28Z

The driver checks the firmware version during initialization.If preemption is supported, the driver configures preemption accordingly and handles userspace preemption requests. Otherwise, the driver returns an error for userspace preemption requests.

accel/amdxdna: Support getting last hardware error

2025-10-16T16:32:48Z

Add new parameter DRM_AMDXDNA_HW_LAST_ASYNC_ERR to get array IOCTL. When hardware reports an error, the driver save the error information and timestamp. This new get array parameter retrieves the last error. Reviewed-by: Mario Limonciello (AMD) Signed-off-by: Lizhi Hou Link: https://lore.kernel.org/r/20251014234119.628453-1-lizhi.hou@amd.com

accel/amdxdna: Add ioctl DRM_IOCTL_AMDXDNA_GET_ARRAY

2025-09-04T15:26:43Z

Add interface for applications to get information array. The application provides a buffer pointer along with information type, maximum number of entries and maximum size of each entry. The buffer may also contain match conditions based on the information type. After the ioctl completes, the actual number of entries and entry size are returned.

accel/amdxdna: Support user space allocated buffer

2025-07-22T15:34:29Z

Enhance DRM_IOCTL_AMDXDNA_CREATE_BO to accept user space allocated buffer pointer. The buffer pages will be pinned in memory. Unless the CAP_IPC_LOCK is enabled for the application process, the total pinned memory can not beyond rlimit_memlock.

accel/amdxdna: Remove DRM_AMDXDNA_HWCTX_CONFIG_NUM

2024-12-17T18:10:07Z

Defining a number of enum elements in uapi header is meaningless. It will not be used as expected and can potentially lead to incompatible issue between user space application and driver.

accel/amdxdna: Add zero check for pad in ioctl input structures

2024-12-17T18:10:05Z

For input ioctl structures, it is better to check if the pad is zero. Thus, the pad bytes might be usable in the future.

accel/amdxdna: Enhance power management settings

2024-12-16T21:50:32Z

Add SET_STATE ioctl to configure device power mode for aie2 device. Three modes are supported initially. POWER_MODE_DEFAULT: Enable clock gating and set DPM (Dynamic Power Management) level to value which has been set by resource solver or maximum DPM level the device supports. POWER_MODE_HIGH: Enable clock gating and set DPM level to maximum DPM level the device supports. POWER_MODE_TURBO: Disable clock gating and set DPM level to maximum DPM level the device supports. Disabling clock gating means all clocks always run on full speed. And the different clock frequency are used based on DPM level been set. Initially, the driver set the power mode to default mode.
