The 4xxx driver can probe 4xxx and 402xx devices. However, the driver
only specifies the firmware images required for 4xxx.
This might result in external tools missing these binaries, if required,
in the initramfs.
Specify the firmware image used by 402xx with the MODULE_FIRMWARE()
macros in the 4xxx driver.

The function adf_send_admin_tl_start() enables the telemetry (TL)
feature on a QAT device by sending the ICP_QAT_FW_TL_START message to
the firmware. This triggers the FW to start writing TL data to a DMA
buffer in memory and returns an array containing the number of
accelerators of each type (slices) supported by this HW.
The pointer to this array is stored in the adf_tl_hw_data data
structure called slice_cnt.
The array slice_cnt is then used in the function tl_print_dev_data()
to report in debugfs only statistics about the supported accelerators.
An incorrect value of the elements in slice_cnt might lead to an out
of bounds memory read.
At the moment, there isn't an implementation of FW that returns a wrong
value, but for robustness validate the slice count array returned by FW.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Due to a lack of alignment in the data sent by requests, the actual DMA
support of the STM32 hash driver is only working with digest calls.
This patch, based on the algorithm used in the driver omap-sham.c,
allows for the usage of DMA in any situation.
It has been functionally tested on STM32MP15, STM32MP13 and STM32MP25.
By checking the performance of this new driver with OpenSSL, the
following results were found:
Performance:
(datasize: 4096, number of hashes performed in 10s)

| 8192 | 53% | 40% | 50% |
| 16384 | 53% | 33% | 50% |
Note: this update doesn't change the driver performance without DMA.
As shown, performance with DMA is slightly lower than without, but in
most cases, it will save CPU time.

The Intel QAT driver provides support for the Diffie-Hellman (DH)
algorithm, limited to prime numbers up to 4K. This driver is used
by default on platforms with integrated QAT hardware for all DH requests.
This has led to failures with algorithms requiring larger prime sizes,
such as ffdhe6144.
alg: ffdhe6144(dh): test failed on vector 1, err=-22
alg: self-tests for ffdhe6144(qat-dh) (ffdhe6144(dh)) failed (rc=-22)

There is a scenario where the file directory is created but the
file memory is not set. In this case, if a user accesses the
file, an error occurs.
So during the creation process of debugfs, memory should be
allocated first before creating the directory. In the release
process, the directory should be deleted first before releasing
the memory to avoid the situation where the memory does not
exist when accessing the directory.
In addition, the directory released by the debugfs is a global
variable. When the debugfs of an accelerator fails to be
initialized, releasing the directory of the global variable
affects the debugfs initialization of other accelerators.
The debugfs root directory released by debugfs init should be a
member of qm, not a global variable.

-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting
ready to enable it globally.
Use the `__struct_group()` helper to separate the flexible array
from the rest of the members in flexible `struct qat_alg_buf_list`,
through tagged `struct qat_alg_buf_list_hdr`, and avoid embedding the
flexible-array member in the middle of `struct qat_alg_fixed_buf_list`.
Also, use `container_of()` whenever we need to retrieve a pointer to
the flexible structure.
So, with these changes, fix the following warnings:

-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting
ready to enable it globally. So, we are deprecating flexible-array
members in the middle of another structure.
There is currently an object (`header`) in `struct nx842_crypto_ctx`
that contains a flexible structure (`struct nx842_crypto_header`):
struct nx842_crypto_ctx {
...
struct nx842_crypto_header header;
struct nx842_crypto_header_group group[NX842_CRYPTO_GROUP_MAX];
...
};
So, in order to avoid ending up with a flexible-array member in the
middle of another struct, we use the `struct_group_tagged()` helper to
separate the flexible array from the rest of the members in the flexible
structure:
struct nx842_crypto_header {
struct_group_tagged(nx842_crypto_header_hdr, hdr,
... the rest of the members
);
struct nx842_crypto_header_group group[];
} __packed;
With the change described above, we can now declare an object of the
type of the tagged struct, without embedding the flexible array in the
middle of another struct:
struct nx842_crypto_ctx {
...
struct nx842_crypto_header_hdr header;
struct nx842_crypto_header_group group[NX842_CRYPTO_GROUP_MAX];
...
} __packed;
We also use `container_of()` whenever we need to retrieve a pointer to
the flexible structure, through which we can access the flexible
array if needed.
So, with these changes, fix the following warning:

Add logic to implement the interface for live migration defined in
qat/qat_mig_dev.h. This is specific for QAT GEN4 Virtual Functions
(VFs).
This introduces a migration data manager which is used to handle the
device state during migration. The manager ensures that the device state
is stored in a format that can be restored in the destination node.
The VF state is organized into a hierarchical structure that includes a
preamble, a general state section, a MISC bar section and an ETR bar
section. The latter contains the state of the 4 ring pairs contained on
a VF. Here is a graphical representation of the state:
preamble | general state section | leaf state
| MISC bar state section| leaf state
| ETR bar state section | bank0 state section | leaf state
| bank1 state section | leaf state
| bank2 state section | leaf state
| bank3 state section | leaf state
In addition to the implementation of the qat_migdev_ops interface and
the state manager framework, add a mutex in pfvf to avoid pf2vf messages

Move and rename ADF_4XXX_PF2VM_OFFSET and ADF_4XXX_VM2PF_OFFSET to
ADF_GEN4_PF2VM_OFFSET and ADF_GEN4_VM2PF_OFFSET respectively.
These definitions are moved from adf_gen4_pfvf.c to adf_gen4_hw_data.h
as they are specific to GEN4 and not just to qat_4xxx.
This change is made in anticipation of their use in live migration.

Add and use the new helper function adf_get_etr_base() which retrieves
the virtual address of the ring bar.
This will be used extensively when adding support for Live Migration.

Pull crypto fixes from Herbert Xu:
"This fixes a regression that broke iwd as well as a divide by zero in
iaa"

crypto: iaa - Fix nr_cpus < nr_iaa case
Revert "crypto: pkcs7 - remove sha1 support"
|
|
If nr_cpus < nr_iaa, the calculated cpus_per_iaa will be 0, which
causes a divide-by-0 in rebalance_wq_table().
Make sure cpus_per_iaa is 1 in that case, and also in the nr_iaa == 0
case, even though cpus_per_iaa is never used if nr_iaa == 0, for
paranoia.
