2024-02-26accel/habanalabs: fix glbl error cause handlingTomer Tayar

2024-02-26accel/habanalabs: modify print for skip loading linux FW to debug logTomer Tayar
Skip loading a linux FW image into the device with the current supported ASICs is done for test purposes only. Moreover, for future supported ASICs it is possible that there won't be a need to load such an image. The print in such a case is therefore not needed in most cases, so replace the used dev_info() with dev_dbg().

2024-02-26accel/habanalabs: use kcalloc() instead of kzalloc()Erick Archer
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.

Currently the HMMU page tables reside in the host memory, which will cause host access from the device for every page walk. This can affect PCIe bandwidth in certain scenarios. To prevent that problem, HMMU page tables will be moved to the device memory so the miss transaction will read the hops from there instead of going to the host.

User interrupts are MSIx interrupts coming from Gaudi2, that have specific range of IDs and are assigned to the sole use of the user process that opened the Gaudi2 device (reminder: there can be only a single user process running on Gaudi2 at any given time). The interrupts are allocated and managed by the driver and therefore, the user expects the driver to initialize them properly, which also includes setting the affinity to the related CPU cores of the device's NUMA node to get maximum performance.

2024-02-16drm/amdkfd: Relocate TBA/TMA to opposite side of VM holeFelix Kuehling
The TBA and TMA, along with an unused IB allocation, reside at low addresses in the VM address space. A stray VM fault which hits these pages must be serviced by making their page table entries invalid. The scheduler depends upon these pages being resident and fails, preventing a debugger from inspecting the failure state. By relocating these pages above 47 bits in the VM address space they can only be reached when bits [63:48] are set to 1. This makes it much less likely for a misbehaving program to generate accesses to them. The current placement at VA (PAGE_SIZE*2) is readily hit by a NULL access with a small offset. v2: - Move it to the reserved space to avoid concflicts with Mesa - Add macros to make reserved space management easier v3: - Move VM max PFN calculation into AMDGPU_VA_RESERVED macros Cc: Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@amd.com> Cc: Christian Koenig <christian.koenig@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Jay Cornwall <jay.cornwall@amd.com> Signed-off-by: Felix Kuehling <felix.kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2024-02-14drm/i915/gt: Restart the heartbeat timer when forcing a pulseJohn Harrison
The context persistence code does things like send super high priority heartbeat pulses to ensure any leaked context can still be pre-empted and thus isn't a total denial of service but only a minor denial of service. Unfortunately, it wasn't bothering to restart the heartbeat worker with a fresh timeout. Thus, if a persistent context happened to be closed just before the heartbeat was going to go ping anyway then the forced pulse would get a negligble execution time. And as the forced pulse is super high priority, the worker thread's next step is a reset. Which means a potentially innocent system randomly goes boom when attempting to close a context. So, force a re-schedule of the worker thread with the appropriate timeout.
