This tag contains habanalabs driver changes for v5.13:
- Add support to reset device after the user closes the file descriptor. Because we support a single user, we can reset the device (if needs to) after a user closes its file descriptor to make sure the device is in idle and clean state for the next user. - Add a new feature to allow the user to wait on interrupt. This is needed for future ASICs - Replace GFP_ATOMIC with GFP_KERNEL wherever possible and add code to support failure of allocating with GFP_ATOMIC. - Update code to support the latest firmware image: - More security features are done in the firmware - Remove hard-coded assumptions and replace them with values that are sent to the firmware on loading. - Print device unusable error - Reset device in case the communication between driver and firmware gets out of sync. - Support new PCI device ids for secured GAUDI. - Expose current power draw through the INFO IOCTL. - Support resetting the device upon a request from the BMC (through F/W). - Always use only a single MSI in GAUDI, due to H/W limitation. - Improve data-path code by taking out code from spinlock protection. - Allow user to specify custom timeout per Command Submission. - Some enhancements to debugfs. - Various minor changes and improvements. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEE7TEboABC71LctBLFZR1NuKta54AFAmByAxcTHG9nYWJiYXlA a2VybmVsLm9yZwAKCRBlHU24q1rngLzgB/4gkltBLgkp+VaIK+fb7uB34CY096M1 e8iO7eqxjrjW3YymBaHVYVuaogv9/XD1pUap/rsvw4Ytvb3g390wLjHhsHcSW0AM 8gIswu0VqWWrxphe0ns+ArV4j6JWVBkUQ1QDxp9Ut0qMaUZha/EkfAengMseQbjR 3oaPwrUCpPpl4XfZaBTxTg3RyHtXnzi3cFw2b207D9iX8DS69TtLgMPAj5xN4vO2 lei/4ZRJw/MbJSwvmNJt2d7E7CniLQh9sy7JnMeinpG+WD4GMdx1m0bI8fIuKQ11 GkvVRREGHuQ0YtvTIWi9K+GAwJNqIIw/cW8M3+P1+7WjLWAKkyOTtYk5 =ZHBU -----END PGP SIGNATURE-----
