2023-03-15accel/habanalabs: Drop redundant pci_enable_pcie_error_reporting()Bjorn Helgaas1-5/+0
pci_enable_pcie_error_reporting() enables the device to send ERR_* Messages. Since commit f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"), the PCI core does this for all devices during enumeration, so the driver doesn't need to do it itself. Remove the redundant pci_enable_pcie_error_reporting() call from the driver. Also remove the corresponding pci_disable_pcie_error_reporting() from the driver .remove() path. Note that this only controls ERR_* Messages from the device. An ERR_* Message may cause the Root Port to generate an interrupt, depending on the AER Root Error Command register managed by the AER service driver.

2023-03-15accel/habanalabs: postpone mem_mgr IDR destruction to hpriv_release()Tomer Tayar4-1/+23
The memory manager IDR is currently destroyed when user releases the file descriptor. However, at this point the user context might be still held, and memory buffers might be still in use. Later on, calls to release those buffers will fail due to not finding their handles in the IDR, leading to a memory leak. To avoid this leak, split the IDR destruction from the memory manager fini, and postpone it to hpriv_release() when there is no user context and no buffers are used.

We plan to do soft-reset either by mmio or by using cpucp packet depending on the FW version. We don't want to check FW version in two different places for that (execute soft-reset and wait to soft-reset) so move the waiting to gaudi2_execute_soft_reset. This also makes sense because the cpucp also does the waiting.

2023-03-15accel/habanalabs: add uapi to stall/resume engineKoby Elbaz7-10/+356
The user might want to stall/resume engines to perform power testing for various scenarios. Because our current HL_CS_FLAGS_ENGINE_CORE_COMMAND command only handles the engines' cores, we need to add another opcode for handling entire engine and not just its core. The user supplies an array, where each entry holds the engine's ID and the command to send to the engine. The size of the array is limited by the number of engines in the ASIC (only Gaudi2 is currently supported).

compose_device_in_use_info() was added to handle the snprintf() return value in a single place. However, the buffer size in print_device_in_use_info() is set such that it would be enough for the max possible print, so compose_device_in_use_info() is not really needed. Moreover, scnprintf() can be used instead of snprintf(), to save the check if the return value larger than the given size.

There's a critical section relatively long, where in certain scenarios (e.g., multiple VM allocations) taking a spinlock might cause noticeable performance degradation. 2.
