A range of MSIX vectors are allocated at initialization for the number
needed for RocE and L2. During run-time, if the user increases or
decreases the number of L2 rings, all the MSIX vectors have to be
freed and a new range has to be allocated. This is not optimal and
causes disruptions to RoCE traffic every time there is a change in L2
MSIX.
If the system supports dynamic MSIX allocations, use dynamic
allocation to add new L2 MSIX vectors or free unneeded L2 MSIX
vectors. RoCE traffic is not affected using this scheme.

If dynamic MSIX allocation is supported, additional MSIX can be
allocated at run-time without reinitializing the existing MSIX entries.
The first step to support this dynamic scheme is to allocate a large

Firmware has deprecated support for legacy INTX in 2022 (since v2.27)
and INTX hasn't been tested for many years before that. INTX was
only used as a fallback mechansim in case MSIX wasn't available. MSIX
is always supported by all firmware. If MSIX capability in PCI config
space is not found during probe, abort.

Due to the special handling of the GSCCS in HW, we can't escalate to GT
reset when we receive the reset failure interrupt; the specs indicate
that we should trigger an FLR instead, but we do not have support for
that at the moment, so the HW will stay permanently in a broken state.
We should therefore mark the device as wedged, the same as if the GT
reset had failed.

Note this only happens when the very first random data providing
crypto card appears via hot plug in the system AND is in disabled
state ("deconfig"). Then the initial pull of random data fails and
a re-scan of the AP bus is triggered while already in the middle
of an AP bus scan caused by the appearing new hardware.
The fix is relatively simple once the scenario us understood:
The AP bus force rescan function will immediately return if there
is currently an AP bus scan running with the very same thread id.

There is a use case during early boot with an secure key encrypted
root file system where the paes cipher may try to derive a protected
key from secure key while the AP bus is still in the process of
scanning the bus and building up the zcrypt device drivers. As the
detection of CEX cards also triggers the modprobe of the pkey handler
modules, these modules may come into existence too late.
Yet another use case happening during early boot is for use of an
protected key encrypted swap file(system). There is an ephemeral
protected key read via sysfs to set up the swap file. But this only
works when the pkey_pckmo module is already in - which may happen at a
later time as the load is triggered via CPU feature.
This patch introduces a new function pkey_handler_request_modules()
and invokes it which unconditional tries to load in the pkey handler
modules. This function is called for the in-kernel API to derive a
protected key from whatever and in the sysfs API when the first
attempt to simple invoke the handler function failed.

For some keys there exists an alternative but usually slower
path to convert the key material into a protected key.
This patch introduces a new handler function
slowpath_key_to_protkey()
which provides this alternate path for the CCA and EP11
handler code. With that even the knowledge about how
and when this can be used within the pkey API code can
be removed. So now the pkey API just tries the primary
way and if that fails simple tries the alternative way.

Introduce pkey base kernel code with a simple pkey handler registry.
Regroup the pkey code into these kernel modules:
- pkey is the pkey api supporting the ioctls, sysfs and in-kernel api.
Also the pkey base code which offers the handler registry and
handler wrapping invocation functions is integrated there. This
module is automatically loaded in via CPU feature if the MSA feature
is available.
- pkey-cca is the CCA related handler code kernel module a offering
CCA specific implementation for pkey. This module is loaded in
via MODULE_DEVICE_TABLE when a CEX[4-8] card becomes available.
- pkey-ep11 is the EP11 related handler code kernel module offering an
EP11 specific implementation for pkey. This module is loaded in via
MODULE_DEVICE_TABLE when a CEX[4-8] card becomes available.
- pkey-pckmo is the PCKMO related handler code kernel module. This
module is loaded in via CPU feature if the MSA feature is available,
but on init a check for availability of the pckmo instruction is
performed.
The handler modules register via a pkey_handler struct at the pkey
base code and the pkey customer (that is currently the pkey api code
fetches a handler via pkey handler registry functions and calls the
unified handler functions via the pkey base handler functions.
As a result the pkey-cca, pkey-ep11 and pkey-pckmo modules get
independent from each other and it becomes possible to write new
handlers which offer another kind of implementation without implicit
dependencies to other handler implementations and/or kernel device
drivers.
For each of these 4 kernel modules there is an individual Kconfig
entry: CONFIG_PKEY for the base and api, CONFIG_PKEY_CCA for the PKEY
CCA support handler, CONFIG_PKEY_EP11 for the EP11 support handler and
CONFIG_PKEY_PCKMO for the pckmo support. The both CEX related handler
modules (PKEY CCA and PKEY EP11) have a dependency to the zcrypt api
of the zcrypt device driver.

As a preparation step for introducing a common function API

signatures exposed by the handlers and reworks all the

This is a huge rework of all the pkey kernel module code.
The goal is to split the code into individual parts with
a dedicated calling interface:
- move all the sysfs related code into pkey_sysfs.c
- all the CCA related code goes to pkey_cca.c
- the EP11 stuff has been moved to pkey_ep11.c
- the PCKMO related code is now in pkey_pckmo.c
The CCA, EP11 and PCKMO code may be seen as "handlers" with
a similar calling interface. The new header file pkey_base.h
declares this calling interface. The remaining code in
pkey_api.c handles the ioctl, the pkey module things and the
"handler" independent code on top of the calling interface
invoking the handlers.
This regrouping of the code will be the base for a real
pkey kernel module split into a pkey base module which acts
as a dispatcher and handler modules providing their service.

The issue is GOODIX_HID_PKG_LEN_SIZE is defined as sizeof(u16) which is
type size_t. However, goodix_hid_check_ack_status() returns negative
error codes or potentially a positive but invalid length which is too
small. So when we compare "if ((response_data_len <=
GOODIX_HID_PKG_LEN_SIZE)" then negative error codes are type promoted to
size_t and counted as a positive large value and treated as valid.
It would have been easy enough to add some casting to avoid the type
promotion, however this patch takes a more thourough approach and moves
the length check into goodix_hid_check_ack_status(). Now the function
only return negative error codes or zero on success and the length
pointer is never set to an invalid length.

Add notifier function for PLL0 clock. In the function, the cpu_root clock
should be operated by saving its current parent and setting a new safe
parent (osc clock) before setting the PLL0 clock rate. After setting PLL0
rate, it should be switched back to the original parent clock.

will run into a TX timeout and flood the kernel log. So log only the

The QUPs aren't shared in a way that requires parking the RCG at an
always on parent in case some other entity turns on the clk. The
hardware is capable of setting a new frequency itself with the DFS mode,
so parking is unnecessary. Furthermore, there aren't any GDSCs for these
devices, so there isn't a possibility of the GDSC turning on the clks
for housekeeping purposes.
Like for the SM8550 GCC QUP clocks at [1], do not use shared clk_ops for QUPs.
