Commit c1ec54b7b5af
("drm/mediatek: Use mailbox rx_callback instead of cmdq_task_cb")
would cause numerous mtk cmdq mailbox driver warning:
WARNING: CPU: 0 PID: 0 at drivers/mailbox/mtk-cmdq-mailbox.c:198

100GbE Intel Wired LAN Driver Updates 2021-10-11
Wojciech Drewek says:
This series adds support for adding/removing advanced switch filters
in ice driver. Advanced filters are building blocks for HW acceleration
of TC orchestration. Add ndo_setup_tc callback implementation for PF and
VF port representors (when device is configured in switchdev mode).
Define dummy packet headers to allow adding advanced rules in HW.
Supported headers, and thus filters, are:
- MAC + IPv4 + UDP
- MAC + VLAN + IPv4 + UDP
- MAC + IPv4 + TCP
- MAC + VLAN + IPv4 + TCP
- MAC + IPv6 + UDP
- MAC + VLAN + IPv6 + UDP
- MAC + IPv6 + TCP

Add driver for Qualcomm PCIe Endpoint controller based on the DesignWare
core with added Qualcomm-specific wrapper around the core. The driver
support is very basic such that it supports only enumeration, PCIe
read/write, and MSI. There is no ASPM and PM support for now but these will
be added later.
The driver is capable of using the PERST# and WAKE# side-band GPIOs for
operation and written on top of the DWC PCI framework.

In certain cases we need a variant of pci_read_vpd()/pci_write_vpd() that
does not check against dev->vpd.len. Such cases are:
- Reading VPD if dev->vpd.len isn't set yet (in pci_vpd_size())
- Devices that map non-VPD information to arbitrary places in VPD address
space (example: Chelsio T3 EEPROM write-protect flag)
Therefore add pci_read_vpd_any() and pci_write_vpd_any() that check against
PCI_VPD_MAX_SIZE only.

Function checks if the rule is presented on regular rules list or

Define dummy packet headers to allow adding advanced rules in HW. This
header is used as admin queue command parameter for adding a rule.
The firmware will extract correct fields and will use them in look ups.
Define each supported packets header and offsets to words used in recipe.
Supported headers:
- MAC + IPv4 + UDP
- MAC + VLAN + IPv4 + UDP
- MAC + IPv4 + TCP
- MAC + VLAN + IPv4 + TCP
- MAC + IPv6 + UDP
- MAC + VLAN + IPv6 + UDP
- MAC + IPv6 + TCP
- MAC + VLAN + IPv6 + TCP
Add code for creating an advanced rule. Rule needs to match defined
dummy packet, if not return error, which means that this type of rule
isn't currently supported.
The first step in adding advanced rule is searching for an advanced
recipe matching this kind of rule. If it doesn't exist new recipe is
created. Dummy packet has to be filled with the correct header field
value from the rule definition. It will be used to do look up in HW.
Support searching for existing advance rule entry. It is used in case
of adding the same rule on different VSI. In this case, instead of
creating new rule, the existing one should be updated with refreshed VSI
list.
Add initialization for prof_res_bm_init flag to zero so that
the possible resource for fv in the files can be initialized.

These changes introduce code for creating advanced recipes for the
switch in hardware.
There are a couple of recipes already defined in the HW. They apply to
matching on basic protocol headers, like MAC, VLAN, MACVLAN,
ethertype or direction (promiscuous), etc.. If the user wants to match on
other protocol headers (eg. ip address, src/dst port etc.) or different
variation of already supported protocols, there is a need to create
new, more complex recipe. That new recipe is referred as
'advanced recipe', and the filtering rule created on top of that recipe
is called 'advanced rule'.
One recipe can have up to 5 words, but the first word is always reserved
for match on switch id, so the driver can define up to 4 words for one
recipe. To support recipes with more words up to 5 recipes can be
chained, so 20 words can be programmed for look up.
Input for adding recipe function is a list of protocols to support. Based
on this list correct profile is being chosen. Correct profile means
that it contains all protocol types from a list. Each profile have up to
48 field vector words and each of this word have protocol id and offset.
These two fields need to match with input data for adding recipe
function. If the correct profile can't be found the function returns an
error.
The next step after finding the correct profile is grouping words into
groups. One group can have up to 4 words. This is done to simplify
sending recipes to HW (because recipe also can have up to 4 words).
In case of chaining (so when look up consists of more than 4 words) last
recipe will always have results from the previous recipes used as words.
A recipe to profile map is used to store information about which profile
is associate with this recipe. This map is an array of 64 elements (max
number of recipes) and each element is a 256 bits bitmap (max number of
profiles)

Implement functions to manage profiles and field vectors in hardware.
In hardware, there are up to 256 profiles and each of these profiles can
have 48 field vector words. Each field vector word is described by
protocol id and offset in the packet. To add a new recipe all used
profiles need to be searched. If the profile contains all required
protocol ids and offsets from the recipe it can be used. The driver has
to add this profile to recipe association to tell hardware that newly
added recipe is going to be associated with this profile.
The amount of used profiles depend on the package. To avoid searching
across not used profile, max profile id value is calculated at init flow.
The profile is considered as unused when all field vector words in the
profile are invalid (protocol id 0xff and offset 0x1ff).
Profiles are read from the package section ICE_SID_FLD_VEC_SW. Empty
field vector words can be used for recipe results. Store all unused field
vector words in prof_res_bm. It is a 256 elements array (max number of
profiles) each element is a 48 bit bitmap (max number of field vector
words).
For now, support only non-tunnel profiles type.

When doing "rmmod ath11k_pci", ath11k performs global SOC reset

log below:

...
This issue is also observed in SSR process, cause a similar
sequence as above is performed.
Such an invalid access occurs because, during rmmod or SSR, MSI
address is cleared but HW MSI functionality not disabled, thus HW
target is able to raise an MSI transaction with 0 as MSI address.
So it can be fixed by simply disabling MSI before reset. For SSR,
since MSI functionality is still needed after target is brought
back, we need to reenable it.
Also change naming of some interfaces related.

existing recipes code.
Only default recipes can be updated. An update is done by reading recipes
from HW, changing their params and calling add recipe command.
Support following admin queue commands:
- ice_aqc_opc_add_recipe (0x0290) - create a recipe with protocol
header information and other details that determine how this recipe
filter works
- ice_aqc_opc_recipe_to_profile (0x0291) - associate a switch recipe
to a profile
- ice_aqc_opc_get_recipe (0x0292) - get details of an existing recipe
- ice_aqc_opc_get_recipe_to_profile (0x0293) - get a recipe associated
with profile ID
Define ICE_AQC_RES_TYPE_RECIPE resource type to hold a switch
recipe. It is needed when a new switch recipe needs to be created.

SAR information from BIOS may come in non sequential pattern.
To overcome the issue, a check is made to extract the right SAR
information using the device mode which is currently being used.

Cache the count of shared fences in the iterator to avoid dereferencing
the dma_resv_object outside the RCU protection. Otherwise iterator and its

The int3472-discrete driver can enter an error path after initialising
int3472->clock.ena_gpio, but before it has registered the clock. This will
cause a NULL pointer dereference, because clkdev_drop() is not null aware.
Instead of guarding the call to skl_int3472_unregister_clock() by checking
for .ena_gpio, check specifically for the presence of the clk_lookup, which
will guarantee clkdev_create() has already been called.

The comment decribing the IPC timeout hadn't been updated when the
actual timeout was changed from 3 to 5 seconds in
commit a7d53dbbc70a ("platform/x86: intel_scu_ipc: Increase virtual
timeout from 3 to 5 seconds") .
Since the value is anyway updated to 10s now, take this opportunity to
update the value in the comment too.

Commit a7d53dbbc70a ("platform/x86: intel_scu_ipc: Increase virtual
timeout from 3 to 5 seconds") states that the recommended timeout range
is 5-10 seconds. Adjust the timeout value to the higher of those i.e 10
seconds, to account for situations where the 5 seconds is insufficient
for disconnect command success.
