accel/ivpu: Fix WARN in ivpu_ipc_send_receive_internal()

2024-12-27T13:02:16Z

commit 0f6482caa6acdfdfc744db7430771fe7e6c4e787 upstream. Move pm_runtime_set_active() to ivpu_pm_init() so when ivpu_ipc_send_receive_internal() is executed before ivpu_pm_enable() it already has correct runtime state, even if last resume was not successful.

accel/ivpu: Prevent recovery invocation during probe and resume

2024-12-05T13:01:44Z

[ Upstream commit 5eaa497411197c41b0813d61ba3fbd6267049082 ] Refactor IPC send and receive functions to allow correct handling of operations that should not trigger a recovery process. Expose ivpu_send_receive_internal(), which is now utilized by the D0i3 entry, DCT initialization, and HWS initialization functions. These functions have been modified to return error codes gracefully, rather than initiating recovery. The updated functions are invoked within ivpu_probe() and ivpu_resume(), ensuring that any errors encountered during these stages result in a proper teardown or shutdown sequence. The previous approach of triggering recovery within these functions could lead to a race condition, potentially causing undefined behavior and kernel crashes due to null pointer dereferences.

accel/ivpu: Fix NOC firewall interrupt handling

2024-10-30T09:17:00Z

The NOC firewall interrupt means that the HW prevented unauthorized access to a protected resource, so there is no need to trigger device reset in such case. To facilitate security testing add firewall_irq_counter debugfs file that tracks firewall interrupts.

accel/ivpu: Add missing MODULE_FIRMWARE metadata

2024-07-15T09:13:04Z

Modules that load firmware from various paths at runtime must declare those paths at compile time, via the MODULE_FIRMWARE macro, so that the firmware paths are included in the module's metadata. The accel/ivpu driver loads firmware but lacks this metadata, preventing dracut from correctly locating firmware files. Fix it.

accel/ivpu: Increase autosuspend delay to 100ms on 40xx

The new HW is more power efficient and there is no need to enter the D0i3/D3 so quickly. Increasing autosuspend delay reduces latency in certain usage scenarios.
