crypto: qat - change value of default idle filter

2023-09-13T07:48:00Z

[ Upstream commit 0f942bdfe9d463be3073301519492f8d53c6b2d5 ] The power management configuration of 4xxx devices is too aggressive and in some conditions the device might be prematurely put to a low power state. Increase the idle filter value to prevent that. In future, this will be set by firmware.

crypto: qat - unmap buffers before free for RSA

2023-07-19T14:36:19Z

[ Upstream commit d776b25495f2c71b9dbf1f5e53b642215ba72f3c ] The callback function for RSA frees the memory allocated for the source and destination buffers before unmapping them. This sequence is wrong. Change the cleanup sequence to unmap the buffers before freeing them.

Pull driver core updates from Greg KH: "Here is the large set of driver core changes for 6.4-rc1. Once again, a busy development cycle, with lots of changes happening in the driver core in the quest to be able to move "struct bus" and "struct class" into read-only memory, a task now complete with these changes. This will make the future rust interactions with the driver core more "provably correct" as well as providing more obvious lifetime rules for all busses and classes in the kernel. The changes required for this did touch many individual classes and busses as many callbacks were changed to take const * parameters instead. All of these changes have been submitted to the various subsystem maintainers, giving them plenty of time to review, and most of them actually did so. Other than those changes, included in here are a small set of other things: - kobject logging improvements - cacheinfo improvements and updates - obligatory fw_devlink updates and fixes - documentation updates - device property cleanups and const * changes - firwmare loader dependency fixes. All of these have been in linux-next for a while with no reported problems" * tag 'driver-core-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (120 commits) device property: make device_property functions take const device * driver core: update comments in device_rename() driver core: Don't require dynamic_debug for initcall_debug probe timing firmware_loader: rework crypto dependencies firmware_loader: Strip off \n from customized path zram: fix up permission for the hot_add sysfs file cacheinfo: Add use_arch[|_cache]_info field/function arch_topology: Remove early cacheinfo error message if -ENOENT cacheinfo: Check cache properties are present in DT cacheinfo: Check sib_leaf in cache_leaves_are_shared() cacheinfo: Allow early level detection when DT/ACPI info is missing/broken cacheinfo: Add arm64 early level initializer implementation cacheinfo: Add arch specific early level initializer tty: make tty_class a static const structure driver core: class: remove struct class_interface * from callbacks driver core: class: mark the struct class in struct class_interface constant driver core: class: make class_register() take a const * driver core: class: mark class_release() as taking a const * driver core: remove incorrect comment for device_create* MIPS: vpe-cmp: remove module owner pointer from struct class usage. ...

crypto: qat - Move driver to drivers/crypto/intel/qat

2023-04-06T08:41:28Z

With the growing number of Intel crypto drivers, it makes sense to group them all into a single drivers/crypto/intel/ directory. Signed-off-by: Tom Zanussi Signed-off-by: Herbert Xu
