f4d7b8a6 - accel/amdxdna: Enhance power management settings

Fri, 13 Dec 2024 23:29:31 +0000

accel/amdxdna: Enhance power management settingsAdd 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 PowerManagement) level to value which has been set by resource solver ormaximum DPM level the device supports.POWER_MODE_HIGH: Enable clock gating and set DPM level to maximum DPMlevel the device supports.POWER_MODE_TURBO: Disable clock gating and set DPM level to maximum DPMlevel the device supports.Disabling clock gating means all clocks always run on full speed. Andthe different clock frequency are used based on DPM level been set.Initially, the driver set the power mode to default mode.Co-developed-by: Narendra Gutta Signed-off-by: Narendra Gutta Co-developed-by: George Yang Signed-off-by: George Yang Reviewed-by: Mario Limonciello Signed-off-by: Lizhi Hou Signed-off-by: Mario Limonciello Link: https://patchwork.freedesktop.org/patch/msgid/20241213232933.1545388-4-lizhi.hou@amd.com List of files: /linux-6.15/drivers/accel/amdxdna/Makefile

4fd4ca98 - accel/amdxdna: Add error handling

Mon, 18 Nov 2024 17:29:41 +0000

accel/amdxdna: Add error handlingWhen there is a hardware error, the NPU firmware notifies the host througha mailbox message. The message includes details of the error, such as thetile and column indexes where the error occurred.The driver starts a thread to handle the NPU error message. The threadstops the clients which are using the column where error occurred. Thenthe driver resets that column.Co-developed-by: Min Ma Signed-off-by: Min Ma Reviewed-by: Jeffrey Hugo Signed-off-by: Lizhi Hou Signed-off-by: Jeffrey Hugo Link: https://patchwork.freedesktop.org/patch/msgid/20241118172942.2014541-10-lizhi.hou@amd.com List of files: /linux-6.15/drivers/accel/amdxdna/Makefile

ac49797c - accel/amdxdna: Add GEM buffer object management

Mon, 18 Nov 2024 17:29:38 +0000

accel/amdxdna: Add GEM buffer object managementThere different types of BOs are supported:- shmemA user application uses shmem BOs as input/output for its workload runningon NPU.- device memory heapThe fixed size buffer dedicated to the device.- device bufferThe buffer object allocated from device memory heap.- command bufferThe buffer object created for delivering commands. The command bufferobject is small and pinned on creation.New IOCTLs are added: CREATE_BO, GET_BO_INFO, SYNC_BO. SYNC_BO is usedto explicitly flush CPU cache for BO memory.Co-developed-by: Min Ma Signed-off-by: Min Ma Reviewed-by: Jeffrey Hugo Signed-off-by: Lizhi Hou Signed-off-by: Jeffrey Hugo Link: https://patchwork.freedesktop.org/patch/msgid/20241118172942.2014541-7-lizhi.hou@amd.com List of files: /linux-6.15/drivers/accel/amdxdna/Makefile

accel/amdxdna: Add hardware contextThe hardware can be shared among multiple user applications. Thehardware resources are allocated/freed based on the request fromuser application via driver IOCTLs.DRM_IOCTL_AMDXDNA_CREATE_HWCTXAllocate tile columns and create a hardware context structure to track theusage and status of the resources. A hardware context ID is returned forXDNA command execution.DRM_IOCTL_AMDXDNA_DESTROY_HWCTXRelease hardware context based on its ID. The tile columns belong tothis hardware context will be reclaimed.DRM_IOCTL_AMDXDNA_CONFIG_HWCTXConfig hardware context.
