Skip loading a linux FW image into the device with the current supported ASICs is done for test purposes only.

2024-02-26accel/habanalabs: use kcalloc() instead of kzalloc()Erick Archer1-1/+1
As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the purpose specific kcalloc() function instead of the argument size * count in the kzalloc() function.

2024-02-12PM: runtime: Simplify pm_runtime_get_if_active() usageSakari Ailus1-1/+1
There are two ways to opportunistically increment a device's runtime PM usage count, calling either pm_runtime_get_if_active() or pm_runtime_get_if_in_use(). The former has an argument to tell whether to ignore the usage count or not, and the latter simply calls the former with ign_usage_count set to false. The other users that want to ignore the usage_count will have to explicitly set that argument to true which is a bit cumbersome. To make this function more practical to use, remove the ign_usage_count argument from the function. The main implementation is in a static function called pm_runtime_get_conditional() and implementations of pm_runtime_get_if_active() and pm_runtime_get_if_in_use() are moved to runtime.c.

2024-02-12accel/ivpu: Fix DevTLB errors on suspend/resume and recoveryJacek Lawrynowicz2-29/+54
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.

Buffers still can't be shared among VPU contexts because each has its own MMU mapping and ivpu_bo only supports single MMU mappings.

Pull drm updates from Dave Airlie: "This contains two major new drivers: - imagination is a first driver for Imagination Technologies devices, it only covers very specific devices, but there is hope to grow it - xe is a reboot of the i915 GPU (shares display) side using a more upstream focused development model, and trying to maximise code sharing. It's not enabled for any hw by default, and will hopefully get switched on for Intel's Lunarlake. This also drops a bunch of the old UMS ioctls. It's been dead long enough. amdgpu has a bunch of new color management code that is being used in the Steam Deck. amdgpu also has a new ACPI WBRF interaction to help avoid radio interference. Otherwise it's the usual lots of changes in lots of places. Detailed summary: new drivers: - imagination - new driver for Imagination Technologies GPU - xe - new driver for Intel GPUs using core drm concepts core: - add CLOSE_FB ioctl - remove old UMS ioctls - increase max objects to accomodate AMD color mgmt encoder: - create per-encoder debugfs directory edid: - split out drm_eld - SAD helpers - drop edid_firmware module parameter format-helper: - cache format conversion buffers sched: -
