2021-09-15crypto: qat - do not ignore errors from enable_vf2pf_comms()Giovanni Cabiddu1-2/+3
[ Upstream commit 5147f0906d50a9d26f2b8698cd06b5680e9867ff ] The function adf_dev_init() ignores the error code reported by enable_vf2pf_comms(). If the latter fails, e.g. the VF is not compatible with the pf, then the load of the VF driver progresses. This patch changes adf_dev_init() so that the error code from enable_vf2pf_comms() is returned to the caller.

2015-03-23crypto: qat - make error and info log messages more descriptiveAllan, Bruce W1-33/+50
Convert pr_info() and pr_err() log messages to dev_info() and dev_err(), respectively, where able. This adds the module name and PCI B:D:F to indicate which QAT device generated the log message. The "QAT:" is removed from these log messages as that is now unnecessary. A few of these log messages have additional spelling/contextual fixes.

2015-01-13crypto: qat - fix device reset flowAllan, Bruce W1-11/+80
When the device needs a reset, e.g. when an uncorrectable PCIe AER event occurs, various services/data structures need to be cleaned up, the hardware reset and the services/data structures initialized and started. The code to perform the cleanup and initialization was not performed when a device reset was done. This patch moves some of the initialization code out of the .probe entry- point into a separate function that is now called during probe as well as after the hardware has been reset. Similarly, a new function is added for first cleaning up these services/data structures prior to resetting. The new functions are adf_dev_init() and adf_dev_shutdown(), respectively, for which there are already prototypes but no actual functions just yet and are now called when the device is reset and during probe/cleanup of the driver. The down and up flows via ioctl calls has similarly been updated. In addition, there are two other bugs in the reset flow - one in the logic for determining whether to schedule a device reset upon receiving an uncorrectable AER event which prevents the reset flow from being initiated, and another with clearing the status bit indicating a device is configured (when resetting the device the configuration remains across the reset so the bit should not be cleared, otherwise, the necessary services will not be re-started in adf_dev_start() after the reset - clear the bit only when actually deleting the configuration).
