accel/ivpu: Don't enable any tiles by default on VPU40xx

2024-02-20T15:56:21Z

There is no point in requesting 1 tile on VPU40xx as the FW will probably need more tiles to run workloads, so it will have to reconfigure PLL anyway. Don't enable any tiles and allow the FW to perform initial tile configuration. This improves NPU boot stability as the tiles are always enabled only by the FW from the same initial state.

accel/ivpu: Fix DevTLB errors on suspend/resume and recovery

2024-02-12T08:00:44Z

Issue IP reset before shutdown in order to complete all upstream requests to the SOC. Without this DevTLB is complaining about incomplete transactions and NPU cannot resume from suspend. This problem is only happening on recent IFWI releases. IP reset in rare corner cases can mess up PCI configuration, so save it before the reset. After this happens it is also impossible to issue PLL requests and D0->D3->D0 cycle is needed to recover the NPU. Add WP 0 request on power up, so the PUNIT is always notified about NPU reset. Use D0/D3 cycle for recovery as it can recover from failed IP reset and FLR cannot.

accel/ivpu: Add job status for jobs aborted by the driver

2024-02-06T12:37:34Z

Add DRM_IVPU_JOB_STATUS_ABORTED to indicate that the job was aborted by the driver due to e.g. TDR or user context MMU faults. This will help UMD and tests distinguish if job was aborted by the FW or the driver.

accel/ivpu: Correct MMU queue size checking functions

2024-02-06T12:36:33Z

Do not use kernel CIRC_SPACE and CIRC_CNT that incorrectly return space of a queue when wrap bit was set. Use correct implementation that compares producer, consumer and wrap bit values. Without this fix it was possible to lose events in case when event queue was full.

Set AW_SNOOP_OVERRIDE bit in VPU_37/40XX_HOST_IF_TCU_PTW_OVERRIDES to force snooping for MMU write accesses (setting event queue events). MMU event queue buffer is the only buffer written by MMU and mapped as write-back which break cache coherency. Force write transactions to be snooped solving the problem.
