qat: Export missing symbols in qat_common

2025-12-29T16:13:53+00:00

Some symbols required by dependent modules were missing from
qat_common.ko and qat_api.ko, causing load failures when local symbol
resolution is disabled.

qat: add disable safe dc mode for QAT SPR devices

2025-06-06T13:42:58+00:00

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 VF driver support

2023-06-12T17:44:01+00:00

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 VF driver support.
- Device configurability via sysctls.
- UIO support for Intel® 4xxx Series devices.

qat: Add Intel® 4xxx Series platform support

2023-01-24T15:33:50+00:00

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.

LinuxKPI: define LINUXKPI_INCLUDES for module builds as well

2022-09-26T19:34:01+00:00

While for in-kernel we already have LINUXKPI_INCLUDES in kern.pre.mk
for kmod builds we've not had a common define to use leading to various
spellings of include paths.

In order for the include list to be expanded more easily in the future,
e.g., adding the "dummy" includes (for all) and to harmonize code,
duplicate LINUXKPI_INCLUDES to kmod.mk and use it for all module Makefiles.

qat: Move CWARNFLAGS down so it works.

2022-09-02T21:52:55+00:00

CWARNFLAGS must be added to after including kern.mk, otherwise all the
warnings set in kern.mk are ignored.  This is why the
-Wmissing-prototypes warnings were not seen previously.

While here, drop -Wno-pointer-sign as it is doesn't seem to be needed,
but add -Wno-cast-qual to silence warnings for various casts of const
pointers to non-const pointers.
