To ensure that each accel driver has an implied dependency on CONFIG_DRM, enclose the entire Kconfig file in an if/endif check.

Currently only the files were moved (including the uapi file which was also renamed). This doesn't include registering to the accel subsystem. This will probably be only in the next kernel version. - In case of decoder error (axi error) in Gaudi2, we can now find the exact IP that initiated the erroneous transaction and print the details for better debug. - Add more trace events. We now can trace mmio transactions and communication with the preboot firmware. - Add to Gaudi2 support for abrupt reset that is done by the firmware. This was support so far only for Gaudi1. - Add uAPI to flush memory transactions (to the device memory). This is needed by the communications library in case of doing p2p with a host NIC which access our HBM directly through the PCI BAR. - Add uAPI to pass-through a request from user-space to firmware and get the result back to user-space. This will allow the driver code to avoid the need to add new packet (in the communication channel with the firmware) for every new request type. - Remove the option to export dma-buf by memory allocation handle in our uAPI. This was planned for Gaudi2 but was never used. Instead, we will do export by memory address (same as Gaudi1). In addition, we added the option to specify an offset to the address. This is needed in Gaudi2 because there the user allocates the entire HBM in one allocation, but would like to export only small part of it. - Multiple bug fixes, refactors and small optimizations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a decode error happens, we often don't know the exact root cause (the erroneous address that was accessed) and the exact engine that created the erroneous transaction. To find out, we need to go over all the relevant register blocks in the ASIC. Once we find the relevant engine, we print its details and the offending address. This helps tremendously when debugging an error that was created by running a user workload.

In such a case we do not support certain reset types, e.g., all kinds of soft-resets (compute reset, inference soft-reset), and reset upon device release. A hard-reset is the only way that an unusable device can change its status. All other reset procedures can't put the device in a reset procedure, which might ultimately cause the device to change its status, unintentionally, to become operational again. Such a scenario has recently occurred, when a user requested a hard-reset while another heavy user workload was ongoing (reset request is queued). Since the workload couldn't finish within reset's timeout limits, the reset has failed and set a device status malfunction. Eventually, when the user released the FD, an unsuccessful soft-reset occurred, hence followed by an additional hard-reset that changed the ASICs status back to be operational.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Zero-length arrays are deprecated[1] and we are moving towards adopting C99 flexible-array members instead. So, replace zero-length arrays in a couple of structures with flex-array members. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [2].

In order to avoid internal races, the driver verifies the device is idle before submitting the register clear job. This check introduces an issue, as debug mode will cause the device to be non-idle which will lead to device acquire failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each of the user contexts has two command queues, one for compute engine and one for the copy engine. Command queues are allocated and registered in the device when the first job (command buffer) is submitted from the user space to the VPU device. The userspace provides a list of GEM buffer object handles to submit to the VPU, the driver resolves buffer handles, pins physical memory if needed, increments ref count for each buffer and stores pointers to buffer objects in the ivpu_job objects that track jobs submitted to the device. The VPU signals job completion with an asynchronous message that contains the job id passed to firmware when the job was submitted. Currently, the driver supports simple scheduling logic where jobs submitted from user space are immediately pushed to the VPU device command queues. In the future, it will be extended to use hardware base scheduling and/or drm_sched.

Context with ID 0 (global context) is created upon driver initialization and it's mainly used for mapping memory required to execute the firmware.
