37b14f2d - crypto: qat - enable dc chaining service

Thu, 14 Sep 2023 14:14:13 +0000

crypto: qat - enable dc chaining serviceQAT GEN4 devices support chained compression operations. Theseallow, with a single request to firmware, to hash then compressdata.Extend the configuration to enable such mode. The cfg_servicesoperations in sysfs are extended to allow the string "dcc". Whenselected, the driver downloads to the device both the symmetriccrypto and the compression firmware images and sends an admin messageto firmware which enables `chained` operations.In addition, it sets the device's capabilities as the combinationof compression and symmetric crypto capabilities, while excludingthe ICP_ACCEL_CAPABILITIES_CRYPTO_SYMMETRIC bit to indicatethat in this mode, symmetric crypto instances are not supported.When "dcc" is enabled, the device will handle compression requestsas if the "dc" configuration is loaded ("dcc" is a variation of "dc")and the driver will register the acomp algorithms.As for the other extended configurations, "dcc" is only available forqat_4xxx devices and the chaining service will be only accessible fromuser space.Signed-off-by: Adam Guerin Reviewed-by: Giovanni Cabiddu Signed-off-by: Herbert Xu List of files: /linux-6.15/Documentation/ABI/testing/sysfs-driver-qat

crypto: qat - expose pm_idle_enabled through sysfsExpose 'pm_idle_enabled' sysfs attribute. This attribute controls howidle conditions are handled. If it is set to 1 (idle support enabled)when the device detects an idle condition, the driver will transitionthe device to the 'MIN' power configuration.In order to set the value of this attribute for a device, the devicemust be in the 'down' state.This only applies to qat_4xxx generation.Signed-off-by: Lucas Segarra Fernandez Reviewed-by: Giovanni Cabiddu Reviewed-by: Andy Shevchenko Signed-off-by: Herbert Xu List of files: /linux-6.15/Documentation/ABI/testing/sysfs-driver-qat

crypto: qat - extend configuration for 4xxxA QAT GEN4 device can be currently configured for crypto (sym;asym) orcompression (dc).This patch extends the configuration to support more variations of theseservices, download the correct FW images on the device and report thecorrect capabilities on the device based on the configured service.The device can now be configured with the following services:"sym", "asym", "dc", "sym;asym", "asym;sym", "sym;dc", "dc;sym","asym;dc", "dc;asym".With this change, the configuration "sym", "asym", "sym;dc", "dc;sym","asym;dc", "dc;asym" will be accessible only via userspace, i.e. the driverfor those configurations will not register into the crypto framework.Support for such configurations in kernel will be enabled in a laterpatch.The pairs "sym;asym" and "asym;sym" result in identical device config.As do "sym;dc", "dc;sym", and "asym;dc", "dc;asym".Signed-off-by: Adam Guerin Reviewed-by: Giovanni Cabiddu Reviewed-by: Andy Shevchenko Signed-off-by: Herbert Xu List of files: /linux-6.15/Documentation/ABI/testing/sysfs-driver-qat

crypto: qat - expose device state through sysfs for 4xxxExpose the device state through an attribute in sysfs and allow tochange it. This is to stop and shutdown a QAT device in order to changeits configuration.The state attribute has been added to a newly created `qat` attributegroup which will contain all _QAT specific_ attributes.The logic that implements the sysfs entries is part of a new file,adf_sysfs.c. This exposes an entry point to allow the driver to createattributes.The function that creates the sysfs attributes is called from the probefunction of the driver and not in the state machine init function toallow the change of states even if the device is in the down state.In order to restore the device configuration between a transition fromdown to up, the function that configures the devices has been abstractedinto the HW data structure.The `state` attribute is only exposed for qat_4xxx devices.Signed-off-by: Giovanni Cabiddu Co-developed-by: Tomasz Kowallik Signed-off-by: Tomasz Kowallik Reviewed-by: Adam Guerin Reviewed-by: Fiona Trahe Reviewed-by: Wojciech Ziemba Reviewed-by: Vladis Dronov Signed-off-by: Herbert Xu List of files: /linux-6.15/Documentation/ABI/testing/sysfs-driver-qat
