2025-05-05crypto: qat - rename and relocate timer logicGeorge Abraham P
Rename adf_gen4_timer.c to adf_timer.c and adf_gen4_timer.h to adf_timer.h to make the files generation-agnostic. This includes renaming the start() and stop() timer APIs and macro definitions to be generic, allowing for reuse across different device generations. This does not introduce any functional changes.

2025-05-05crypto: qat - include qat_common in top MakefileSuman Kumar Chakraborty
To ensure proper functionality, each specific driver needs to access functions located in the qat_common folder. Move the include path for qat_common to the top-level Makefile. This eliminates the need for redundant include directives in the Makefiles of individual drivers.

2025-04-28crypto: iaa - Adjust workqueue allocation typeKees Cook
In preparation for making the kmalloc family of allocators type aware, we need to make sure that the returned type from the allocation matches the type of the variable being assigned. (Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type is "struct idxd_wq **", but the returned type will be "struct wq **". These are the same size allocation (pointer sized), but the types don't match. Adjust the allocation type to match the assignment.

2025-02-22crypto: qat - refactor service parsing logicMałgorzata Mielnik
The service parsing logic is used to parse the configuration string provided by the user using the attribute qat/cfg_services in sysfs. The logic relies on hard-coded strings. For example, the service "sym;asym" is also replicated as "asym;sym". This makes the addition of new services or service combinations complex as it requires the addition of new hard-coded strings for all possible combinations. This commit addresses this issue by: * reducing the number of internal service strings to only the basic service representations. * modifying the service parsing logic to analyze the service string token by token instead of comparing a whole string with patterns. * introducing the concept of a service mask where each service is represented by a single bit. * dividing the parsing logic into several functions to allow for code reuse (e.g. by sysfs-related functions). * introducing a new, device generation-specific function to verify whether the requested service combination is supported by the currently used device.

2024-12-28crypto: iaa - Fix IAA disabling that occurs when sync_mode is set to 'async'Kanchana P Sridhar
With the latest mm-unstable, setting the iaa_crypto sync_mode to 'async' causes crypto testmgr.c test_acomp() failure and dmesg call traces, and zswap being unable to use 'deflate-iaa' as a compressor: echo async > /sys/bus/dsa/drivers/crypto/sync_mode [ 255.271030] zswap: compressor deflate-iaa not available [ 369.960673] INFO: task cryptomgr_test:4889 blocked for more than 122 seconds.

With 'async', iaa_crypto calls to compress/decompress submit the descriptor and return -EINPROGRESS, without any mechanism in the driver to poll for completions. Hence callers such as test_acomp() in crypto/testmgr.c or zswap, that wrap the calls to crypto_acomp_compress() and crypto_acomp_decompress() in synchronous wrappers, will block indefinitely. Even before zswap can notice this problem, the crypto testmgr.c's test_acomp() will fail and prevent registration of "deflate-iaa" as a valid crypto acomp algorithm, thereby disallowing the use of "deflate-iaa" as a zswap compress (zswap will fall-back to the default compressor in this case). To fix this issue, this patch modifies the iaa_crypto sync_mode set function to treat 'async' equivalent to 'sync', so that the correct and only supported driver async polling without interrupts implementation is enabled, and zswap can use 'deflate-iaa' as the compressor. Hence, with this patch, this is what will happen: echo async > /sys/bus/dsa/drivers/crypto/sync_mode cat /sys/bus/dsa/drivers/crypto/sync_mode sync There are no crypto/testmgr.c test_acomp() errors, no call traces and zswap can use 'deflate-iaa' without any errors. The iaa_crypto documentation has also been updated to mention this caveat with 'async' and what to expect with this fix. True iaa_crypto async polling without interrupts is enabled in patch "crypto: iaa - Implement batch_compress(), batch_decompress() API in iaa_crypto." [1] which is under review as part of the "zswap IAA compress batching" patch-series [2]. Until this is merged, we would appreciate it if this current patch can be considered for a hotfix.

2024-10-19crypto: qat - remove faulty arbiter config resetAhsan Atta
Resetting the service arbiter config can cause potential issues related to response ordering and ring flow control check in the event of AER or device hang. This is because it results in changing the default response ring size from 32 bytes to 16 bytes. The service arbiter config reset also disables response ring flow control check. Thus, by removing this reset we can prevent the service arbiter from being configured inappropriately, which leads to undesired device behaviour in the event of errors.
