crypto: octeontx2 - add support for OcteonTX2 98xx CPT block.

2021-04-22T07:31:31+00:00

OcteonTX2 series of silicons have multiple variants, the
98xx variant has two crypto (CPT0 & CPT1) blocks. This patch
adds support for firmware load on new CPT block(CPT1).

crypto: octeontx2 - fix -Wpointer-bool-conversion warning

2021-02-10T06:56:00+00:00

When CONFIG_CPUMASK_OFFSTACK is disabled, clang reports a warning
about a bogus condition:

drivers/crypto/marvell/octeontx2/otx2_cptlf.c:334:21: error: address of array 'lfs->lf[slot].affinity_mask' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
                if (lfs->lf[slot].affinity_mask)
                ~~  ~~~~~~~~~~~~~~^~~~~~~~~~~~~

In this configuration, the free_cpumask_var() function does nothing,
so the condition could be skipped.

When the option is enabled, there is no warning, but the check
is also redundant because free_cpumask_var() falls back to kfree(),
which is documented as ignoring NULL pointers.

Remove the check to avoid the warning.

crypto: marvell - CRYPTO_DEV_OCTEONTX2_CPT should depend on ARCH_THUNDER2

2021-02-10T06:54:31+00:00

The Marvell OcteonTX2 CPT physical function PCI device is present only
on OcteonTx2 SoC, and not available as an independent PCIe endpoint.
Hence add a dependency on ARCH_THUNDER2, to prevent asking the user
about this driver when configuring a kernel without OcteonTx2 platform
support.

crypto: octeontx2 - Add dependency on NET_VENDOR_MARVELL

2021-02-05T03:32:05+00:00

The crypto octeontx2 driver depends on the mbox code in the network
tree.  It tries to select the MBOX Kconfig option but that option
itself depends on many other options which are not selected, e.g.,
CONFIG_NET_VENDOR_MARVELL.  It would be inappropriate to select them
all as randomly prompting the user for network options which would
oterhwise be disabled just because a crypto driver has been enabled
makes no sense.

This patch fixes this by adding a dependency on NET_VENDOR_MARVELL.
This makes the crypto driver invisible if the network option is off.

If the crypto driver must be visible even without the network stack
then the shared mbox code should be moved out of drivers/net.

crypto: marvell/cesa - Fix use of sg_pcopy on iomem pointer

2021-01-29T05:07:03+00:00

The cesa driver mixes use of iomem pointers and normal kernel
pointers.  Sometimes it uses memcpy_toio/memcpy_fromio on both
while other times it would use straight memcpy on both, through
the sg_pcopy_* helpers.

This patch fixes this by adding a new field sram_pool to the engine
for the normal pointer case which then allows us to use the right
interface depending on the value of engine->pool.

crypto: octeontx2 - register with linux crypto framework

2021-01-22T03:58:03+00:00

CPT offload module utilises the linux crypto framework to offload
crypto processing. This patch registers supported algorithms by
calling registration functions provided by the kernel crypto API.

The module currently supports:
- AES block cipher in CBC,ECB and XTS mode.
- 3DES block cipher in CBC and ECB mode.
- AEAD algorithms.
