089e0e746d wifi: ath12k: add hardware registers for QCC2072
Add hardware registers and populate hw_regs field in
ath12k_wifi7_hw_ver_map for QCC2072. Note for some registers not
defined and not used by QCC2072, a magic value is assigned.

Also populate other fields to be the same with WCN7850. Among them,
however, QCC2072 requires different HAL ops and descriptor size, both
will be updated in upcoming patches.

b5151c9b6e wifi: ath12k: fix mac phy capability parsing
Currently ath12k_pull_mac_phy_cap_svc_ready_ext() assumes only one band
supported in each phy, hence it skips 5 GHz band if 2 GHz band support
is detected. This does not work for device which gets only one phy but
has both bands supported, such as QCC2072.

Change to check each band individually to fix this issue.

6281d4f4df wifi: ath12k: refactor 320 MHz bandwidth support parsing
For single pdev device, 320 MHz bandwidth support is reported only in
capability of WMI_HOST_HW_MODE_SINGLE mode, hence commit d4e244c85e
("wifi: ath12k: enable 320 MHz bandwidth for 6 GHz band in EHT PHY
capability for WCN7850") relaxed the condition check in
ath12k_wmi_tlv_mac_phy_caps_ext() to allow SINGLE mode getting parsed in
ath12k_wmi_tlv_mac_phy_caps_ext_parse(). Since SINGLE mode is not assumed
to be preferred, the function returns unconditionally after parsing 320
MHz support.

This works for WCN7850 because it prefers another mode indeed, while it
breaks QCC2072 since it prefers SINGLE mode. Due to the unconditional
return, the subsequent EHT parsing is skipped. Consequently EHT related
features are disabled.

Refactor it by moving 320 MHz parsing to ath12k_wmi_tlv_mac_phy_caps_ext(),
before the mode checking. This makes the code more straightforward, and
work for both WCN7850 and QCC2072.

7f852de000 wifi: ath12k: fix preferred hardware mode calculation
For single pdev device like WCN7850/QCC2072, preferred_hw_mode is
initialized to WMI_HOST_HW_MODE_SINGLE. Later when firmware sends
supported modes to host, each mode is compared with the initial one
and if the priority of the new mode is higher, update the parameter
and store mode capability.

For WCN7850, this does not result in issue, as one of the supported
mode indeed has a higher priority. However the only available mode of
QCC2072 at this stage is WMI_HOST_HW_MODE_SINGLE, which fails the
comparison, hence mode capability is not stored. Subsequently driver
initialization fails.

Fix it by accepting a mode with the same priority.

1f165022d5 wifi: ath12k: refactor REO status ring handling
The entry of REO status ring of existing chips has a 64 bit TLV header,
hence below functions take a 64 bit TLV assumption by default

        ath12k_wifi7_dp_rx_process_reo_status()
        ath12k_wifi7_hal_reo_status_queue_stats()
        ath12k_wifi7_hal_reo_flush_queue_status()
        ath12k_wifi7_hal_reo_flush_cache_status()
        ath12k_wifi7_hal_reo_unblk_cache_status()
        ath12k_wifi7_hal_reo_flush_timeout_list_status()
        ath12k_wifi7_hal_reo_desc_thresh_reached_status()
        ath12k_wifi7_hal_reo_update_rx_reo_queue_status()

However this is not the case for QCC2072 of which the TLV is 32 bit.

Refactor above functions to prepare for QCC2072 support, this is done by
removing TLV length assumption and offloading TLV decoding work to a newly
added callback _reo_status_dec_tlv_hdr. This way each chip can register
its own handler hence can do the work accordingly.

        ath12k_wifi7_hal_reo_cmd_flush_cache()
        ath12k_wifi7_hal_reo_cmd_update_rx_queue()

However this is not the case for QCC2072 of which the TLV is 32 bit,
meaning above functions don't work for it.

Rename/refactor above functions to prepare for QCC2072 support:

Rename the first one to ath12k_wifi7_hal_reo_init_cmd_ring_tlv64() to
better reflect what it is doing. There will be a 32 bit variant when
QCC2072 support is in place.

For the last ones, remove TLV length assumption and offload TLV encoding
work to a newly added callback _reo_cmd_enc_tlv_hdr. This way each chip
can register its own handler hence can do the work accordingly.

b515730ec3 wifi: ath11k: move .max_tx_ring to struct ath11k_hw_hal_params
".max_tx_ring" is an upper bounds to indexing ".tcl2wbm_rbm_map". It
is initialized in, core.c, a different file than the array. This
spaghetti-like relation is fragile and not obvious. Accidentally
setting ".max_tx_ring" too high leads to a hard to track out-of-
bounds access and memory corruption.

There is a small ambiguity on the meaning of "max_tx_ring":
 - The highest ring, max=3 implies there are 4 rings (0, 1, 2, 3)
 - The highest number to use for array indexing (there are 3 rings)

Clarify this dependency by moving ".max_tx_ring" adjacent to the array
".tcl2wbm_rbm_map", and name it "num_tx_rings". Use ARRAY_SIZE()
instead of #defines to initialize the length field.

The intent is to make the code easier to understand rather than fix
an existing bug.

 * WMI service enabled for the CFR support
   'WMI_TLV_SERVICE_CFR_CAPTURE_SUPPORT'

Also, provide a configuration option CONFIG_ATH11K_CFR to enable CFR
feature support during the compilation time.

CFR module initialization includes Direct Buffer(DB) ring initialization
where hardware uses the DB ring buffers to copy CFR data to host.
Number of buffers and buffer size of the ring is based on the DB ring
capabilities advertised by the firmware through WMI service ready.
Also ring configurations are sent to firmware through
ath11k_dbring_wmi_cfg_setup().

Predefine ath11k_cfr_dma_hdr, ath11k_look_up_table, and ath11k_cfr
structs and fields for subsequent patches.

8fb264d1a0 wifi: ath12k: remove redundant pci_set_drvdata() call
pci_set_drvdata() is called twice in ath12k_pci_probe() with the
same pointer. Remove the earlier call so drvdata is set after
ath12k_base and ath12k_pci initialization is complete.

Having two calls might suggest that drvdata needs to be set early for
some reason, even though it is not used until after the 'ab' struct
ath12k_base is fully populated. Even though exact placement is
not critical, keeping a single pci_set_drvdata() at the end of
the initialization makes it clearer that drvdata points to a
fully initialized structure and avoids confusion for future changes.

a995fe1a3a rust: driver: drop device private data post unbind
Currently, the driver's device private data is allocated and initialized
from driver core code called from bus abstractions after the driver's
probe() callback returned the corresponding initializer.

Similarly, the driver's device private data is dropped within the
remove() callback of bus abstractions after calling the remove()
callback of the corresponding driver.

However, commit 6f61a2637a ("rust: device: introduce
Device::drvdata()") introduced an accessor for the driver's device
private data for a Device<Bound>, i.e. a device that is currently bound
to a driver.

Obviously, this is in conflict with dropping the driver's device private
data in remove(), since a device can not be considered to be fully
unbound after remove() has finished:

We also have to consider registrations guarded by devres - such as IRQ
or class device registrations - which are torn down after remove() in
devres_release_all().

Thus, it can happen that, for instance, a class device or IRQ callback
still calls Device::drvdata(), which then runs concurrently to remove()
(which sets dev->driver_data to NULL and drops the driver's device
private data), before devres_release_all() started to tear down the
corresponding registration. This is because devres guarded registrations
can, as expected, access the corresponding Device<Bound> that defines
their scope.

In C it simply is the driver's responsibility to ensure that its device
private data is freed after e.g. an IRQ registration is unregistered.

Typically, C drivers achieve this by allocating their device private data
with e.g. devm_kzalloc() before doing anything else, i.e. before e.g.
registering an IRQ with devm_request_threaded_irq(), relying on the
reverse order cleanup of devres.

Technically, we could do something similar in Rust. However, the
resulting code would be pretty messy:

In Rust we have to differentiate between allocated but uninitialized
memory and initialized memory in the type system. Thus, we would need to
somehow keep track of whether the driver's device private data object
has been initialized (i.e. probe() was successful and returned a valid
initializer for this memory) and conditionally call the destructor of
the corresponding object when it is freed.

This is because we'd need to allocate and register the memory of the
driver's device private data *before* it is initialized by the
initializer returned by the driver's probe() callback, because the
driver could already register devres guarded registrations within
probe() outside of the driver's device private data initializer.

Luckily there is a much simpler solution: Instead of dropping the
driver's device private data at the end of remove(), we just drop it
after the device has been fully unbound, i.e. after all devres callbacks
have been processed.

For this, we introduce a new post_unbind() callback private to the
driver-core, i.e. the callback is neither exposed to drivers, nor to bus
abstractions.

This way, the driver-core code can simply continue to conditionally
allocate the memory for the driver's device private data when the
driver's initializer is returned from probe() - no change needed - and
drop it when the driver-core code receives the post_unbind() callback.

The problem is that on arm we use alternate storage for pt_regs object
that is passed to bpf_prog_run and if any register is changed (which
is the case of bpf_override_return) it's not propagated back to actual
pt_regs object.

Fixing this by introducing and calling ftrace_partial_regs_update function

88e490913f ftrace fixes for v6.19:
- Fix allocation accounting on boot up
 
   The ftrace records for each function that ftrace can attach to is
   done in a group of pages. At boot up, the number of pages are
   calculated and allocated. After that, the pages are filled with data.
   It may allocate more than needed due to some functions not being
   recorded (because they are unused weak functions), this too is
   recorded.
 
   After the data is filled in, a check is made to make sure the right
   number of pages were allocated. But this was off due to the
   assumption that the same number of entries fit per every page.
   Because the size of an entry does not evenly divide into PAGE_SIZE,
   there is a rounding error when a large number of pages is allocated
   to hold the events. This causes the check to fail and triggers a
   warning.
 
   Fix the accounting by finding out how many pages are actually
   allocated from the functions that allocate them and use that to see
   if all the pages allocated were used and the ones not used are
   properly freed.

   After the data is filled in, a check is made to make sure the right
   number of pages were allocated. But this was off due to the
   assumption that the same number of entries fit per every page.
   Because the size of an entry does not evenly divide into PAGE_SIZE,
   there is a rounding error when a large number of pages is allocated
   to hold the events. This causes the check to fail and triggers a
   warning.

   Fix the accounting by finding out how many pages are actually
   allocated from the functions that allocate them and use that to see
   if all the pages allocated were used and the ones not used are
   properly freed.

0df529f466 dt-bindings: display/msm/rgmu: Document A612 RGMU
RGMU a.k.a Reduced Graphics Management Unit is a small state machine
with the sole purpose of providing IFPC (Inter Frame Power Collapse)
support. Compared to GMU, it doesn't manage GPU clock, voltage
scaling, bw voting or any other functionalities. All it does is detect
an idle GPU and toggle the GDSC switch. As it doesn't access DDR space,
it doesn't require iommu.

So far, only Adreno 612 GPU has an RGMU core. Document it in
qcom,adreno-rgmu.yaml.

fa4525799d dt-bindings: display/msm: gpu: Document A612 GPU
A612 GPU has a new IP called RGMU (Reduced Graphics Management Unit)
which replaces GMU. But it doesn't do clock or voltage scaling. So we
need the gpu core clock in the GPU node along with the power domain to
do clock and voltage scaling from the kernel. Update the bindings to
describe this GPU.

JSON Schema conditionals can become complex and error-prone when combined

e39333a81e drm/msm/a6xx: Retrieve gmu core range by index
Some GPUs like A612 doesn't use a named register range resource. This
is because the reg-name property is discouraged when there is just a
single resource.

To address this, retrieve the 'gmu' register range by its index. It is
always guaranteed to be at index 0.

fbfeca7404 lib/crypto: aes: Drop 'volatile' from aes_sbox and aes_inv_sbox
The volatile keyword is no longer necessary or useful on aes_sbox and
aes_inv_sbox, since the table prefetching is now done using a helper
function that casts to volatile itself and also includes an optimization
barrier.  Since it prevents some compiler optimizations, remove it.

953f2db0bf lib/crypto: aes: Remove old AES en/decryption functions
Now that all callers of the aes_encrypt() and aes_decrypt() type-generic
macros are using the new types, remove the old functions.

Then, replace the macro with direct calls to the new functions, dropping
the "_new" suffix from them.

This completes the change in the type of the key struct that is passed
to aes_encrypt() and aes_decrypt().

bc79efa08c lib/crypto: aesgcm: Use new AES library API
Switch from the old AES library functions (which use struct
crypto_aes_ctx) to the new ones (which use struct aes_enckey).  This
eliminates the unnecessary computation and caching of the decryption
round keys.  The new AES en/decryption functions are also much faster
and use AES instructions when supported by the CPU.

Note that in addition to the change in the key preparation function and
the key struct type itself, the change in the type of the key struct
results in aes_encrypt() (which is temporarily a type-generic macro)
calling the new encryption function rather than the old one.

eliminate the dependency on this field, instead just access the raw key
directly, which is already available in the relevant functions.
