2021-06-18habanalabs: added open_stats info ioctlYuri Nudelman1-0/+12
In a system with multiple ASICs, there is a need to provide monitoring tools with information on how long a device was opened and how many times a device was opened. Therefore, we add a new opcode to the INFO ioctl to provide that information.

2021-06-18habanalabs: add debug flag to prevent failure on timeoutYuri Nudelman1-0/+1
Sometimes it is useful to allow the command to continue running despite the timeout occurred, to differentiate between really stuck or just very time consuming commands. This can be achieved by passing a new debug flag alongside the cs, HL_CS_FLAGS_SKIP_RESET_ON_TIMEOUT. Anyway, if the timeout occurred, a warning print shall be issued, however this shall not fail the submission.

2020-05-19uapi: habanalabs: add signal/wait operationsOmer Shpigelman1-16/+51
This is a pre-requisite to upstreaming GAUDI support. Signal/wait operations are done by the user to perform sync between two Primary Queues (PQs). The sync is done using the sync manager and it is usually resolved inside the device, but sometimes it can be resolved in the host, i.e. the user should be able to wait in the host until a signal has been completed. The mechanism to define signal and wait operations is done by the driver because it needs atomicity and serialization, which is already done in the driver when submitting work to the different queues. To implement this feature, the driver "takes" a couple of h/w resources, and this is reflected by the defines added to the uapi file. The signal/wait operations are done via the existing CS IOCTL, and they use the same data structure. There is a difference in the meaning of some of the parameters, and for that we added unions to make the code more readable.

2020-02-22uacce: add uacce driverKenneth Lee1-0/+38
Uacce (Unified/User-space-access-intended Accelerator Framework) targets to provide Shared Virtual Addressing (SVA) between accelerators and processes. So accelerator can access any data structure of the main cpu. This differs from the data sharing between cpu and io device, which share only data content rather than address. Since unified address, hardware and user space of process can share the same virtual address in the communication. Uacce create a chrdev for every registration, the queue is allocated to the process when the chrdev is opened. Then the process can access the hardware resource by interact with the queue file. By mmap the queue file space to user space, the process can directly put requests to the hardware without syscall to the kernel space. The IOMMU core only tracks mm<->device bonds at the moment, because it only needs to handle IOTLB invalidation and PASID table entries. However uacce needs a finer granularity since multiple queues from the same device can be bound to an mm. When the mm exits, all bound queues must be stopped so that the IOMMU can safely clear the PASID table entry and reallocate the PASID. An intermediate struct uacce_mm links uacce devices and queues. Note that an mm may be bound to multiple devices but an uacce_mm structure only ever belongs to a single device, because we don't need anything more complex (if multiple devices are bound to one mm, then we'll create one uacce_mm for each bond). uacce_device --+-- uacce_mm --+-- uacce_queue | '-- uacce_queue | '-- uacce_mm --+-- uacce_queue +-- uacce_queue '-- uacce_queue Reviewed-by: Greg Kroah-Hartman <[email protected]> Reviewed-by: Jonathan Cameron <[email protected]> Signed-off-by: Kenneth Lee <[email protected]> Signed-off-by: Zaibo Xu <[email protected]> Signed-off-by: Zhou Wang <[email protected]> Signed-off-by: Jean-Philippe Brucker <[email protected]> Signed-off-by: Zhangfei Gao <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
