qat: enable qat driver for 402xx device

2025-09-15T13:48:45Z

Enabled qat driver support for 402xx device with ID 0x4944/0x4945. This is an additional device supported under the existing qat_4xxx driver. Firmwares specific to the 402xx device are added.

qat: move debugfs handling to separate file

2025-06-06T13:43:22Z

Moved handling of debugfs entries to a separate file. In addition, it will allow to consolidate the addition of debugfs entries to a single location in the code. This implementation adds infrastructure to create (and remove) debugfs entries at two different stages. - Done when a device is probed, allows to keep debugfs entries persistent between a transition in device state (up to down or vice versa). - Done after the initialization phase, allows to have debugfs entries that are accessible only when the device is up. In addition, moved the creation of debugfs entries for configuration of the newly created function adf_dbgfs_init() and replace symbolic permissions with octal permissions when creating the debugfs files. Added sysctl oids storage for proper cleanup on device down. Reviewed by: markj, ziaee MFC after: 2 weeks Sponsored by: Intel Corporation Differential Revision: https://reviews.freebsd.org/D50379

qat: add disable safe dc mode for QAT SPR devices

2025-06-06T13:42:58Z

Build and sysctl configuration modes are introduced for QAT SPR devices to disable safe dc mode. A new QAT driver build option ‘QAT_DISABLE_SAFE_DC_MODE’ is required to build the QAT driver with code that allows a request to be sent to FW to override the ‘History Buffer’ mitigation. Default QAT driver builds do not include this ‘QAT_DISABLE_SAFE_DC_MODE’ build option. Even if the QAT driver was built with code that allows a request to be sent to FW to override the ‘History Buffer’ mitigation, the QAT driver must still be configured using sysctl to request an override of the ‘History Buffer’ mitigation if desired. The default QAT driver configuration option sysctl dev.qat.X.disable_safe_dc_mode does not allow override of the mitigation. The new sysctl attribute disable_safe_dc_mode is to be set to 1 for overriding the history buffer mitigation. Firmware for qat_4xxx is updated for this change. If this mode is enabled, decompression throughput increases but may result in a data leak if num_user_processes is more than 1. This option is to be enabled only if your system is not prone to user data leaks.

qat: Add Intel® 4xxx Series platform support

2023-01-24T15:33:50Z

Overview: Intel(R) QuickAssist Technology (Intel(R) QAT) provides hardware acceleration for offloading security, authentication and compression services from the CPU, thus significantly increasing the performance and efficiency of standard platform solutions. This commit introduces: - Intel® 4xxx Series platform support. - QuickAssist kernel API implementation update for Generation 4 device. Enabled services: symmetric cryptography and data compression. - Increased default number of crypto instances in static configuration for performance purposes. OCF backend changes: - changed GCM/CCM MAC validation policy to generate MAC by HW and validate by SW due to the QAT HW limitations.
