d1f862c0b9 One new board the ROC-RK3588-RT, gpu improvements for RK3328, frequency 
scaling for the RK3528 and the very first small steps for camera
 support on the RK3588 - with the CSI-DPHY support, with more hopefully
 to come soon'ish :-) .
 
 And apart from those bigger points, some more individual peripheral work
 on some boards.

8de446fd49 Apple SoC DTS updates for 6.18, part 2 
- New device trees for all M2 Pro, Max and Ultra models are added.
   This is responsible for most of the changed lines since we already
   need 2000+ lines just to describe all the power domains inside
   t602x-pmgr.dtsi for these SoCs.
 - Missing WiFi properties for t600x are added.
 - Bluetooth nodes are added for all t600x machines.
 - The PCIe ethernet iommu-map was fixed for the Apple M1 iMac
   to account for a disabled PCIe port.
 - SPMI, NVMe, SART and mailbox nodes for Apple's T2 and A11.

323302f54d selftests/bpf: Test bpf_xdp_pull_data 
Test bpf_xdp_pull_data() with xdp packets with different layouts. The
xdp bpf program first checks if the layout is as expected. Then, it
calls bpf_xdp_pull_data(). Finally, it checks the 0xbb marker at offset
1024 using directly packet access.

fe9544ed1a bpf: Support specifying linear xdp packet data size for BPF_PROG_TEST_RUN 
To test bpf_xdp_pull_data(), an xdp packet containing fragments as well
as free linear data area after xdp->data_end needs to be created.
However, bpf_prog_test_run_xdp() always fills the linear area with
data_in before creating fragments, leaving no space to pull data. This
patch will allow users to specify the linear data size through
ctx->data_end.

Currently, ctx_in->data_end must match data_size_in and will not be the
final ctx->data_end seen by xdp programs. This is because ctx->data_end
is populated according to the xdp_buff passed to test_run. The linear
data area available in an xdp_buff, max_linear_sz, is alawys filled up
before copying data_in into fragments.

This patch will allow users to specify the size of data that goes into
the linear area. When ctx_in->data_end is different from data_size_in,
only ctx_in->data_end bytes of data will be put into the linear area when
creating the xdp_buff.

While ctx_in->data_end will be allowed to be different from data_size_in,
it cannot be larger than the data_size_in as there will be no data to
copy from user space. If it is larger than the maximum linear data area
size, the layout suggested by the user will not be honored. Data beyond
max_linear_sz bytes will still be copied into fragments.

Finally, since it is possible for a NIC to produce a xdp_buff with empty
linear data area, allow it when calling bpf_test_init() from
bpf_prog_test_run_xdp() so that we can test XDP kfuncs with such
xdp_buff. This is done by moving lower-bound check to callers as most of
them already do except bpf_prog_test_run_skb(). The change also fixes a
bug that allows passing an xdp_buff with data < ETH_HLEN. This can
happen when ctx is used and metadata is at least ETH_HLEN.

7eb83bff02 bpf: Make variables in bpf_prog_test_run_xdp less confusing 
Change the variable naming in bpf_prog_test_run_xdp() to make the
overall logic less confusing. As different modes were added to the
function over the time, some variables got overloaded, making
it hard to understand and changing the code becomes error-prone.

Replace "size" with "linear_sz" where it refers to the size of metadata
and data. If "size" refers to input data size, use test.data_size_in
directly.

Replace "max_data_sz" with "max_linear_sz" to better reflect the fact
that it is the maximum size of metadata and data (i.e., linear_sz). Also,
xdp_rxq.frags_size is always PAGE_SIZE, so just set it directly instead
of subtracting headroom and tailroom and adding them back.

4dce1a0d7c bpf: Support pulling non-linear xdp data 
Add kfunc, bpf_xdp_pull_data(), to support pulling data from xdp
fragments. Similar to bpf_skb_pull_data(), bpf_xdp_pull_data() makes
the first len bytes of data directly readable and writable in bpf
programs. If the "len" argument is larger than the linear data size,
data in fragments will be copied to the linear data area when there
is enough room. Specifically, the kfunc will try to use the tailroom
first. When the tailroom is not enough, metadata and data will be
shifted down to make room for pulling data.

A use case of the kfunc is to decapsulate headers residing in xdp
fragments. It is possible for a NIC driver to place headers in xdp
fragments. To keep using direct packet access for parsing and
decapsulating headers, users can pull headers into the linear data
area by calling bpf_xdp_pull_data() and then pop the header with
bpf_xdp_adjust_head().

dea1526fba bpf: Allow bpf_xdp_shrink_data to shrink a frag from head and tail 
Move skb_frag_t adjustment into bpf_xdp_shrink_data() and extend its
functionality to be able to shrink an xdp fragment from both head and
tail. In a later patch, bpf_xdp_pull_data() will reuse it to shrink an
xdp fragment from head.

Additionally, in bpf_xdp_frags_shrink_tail(), breaking the loop when
bpf_xdp_shrink_data() returns false (i.e., not releasing the current
fragment) is not necessary as the loop condition, offset > 0, has the
same effect. Remove the else branch to simplify the code.

8f12d1137c bpf: Clear pfmemalloc flag when freeing all fragments 
It is possible for bpf_xdp_adjust_tail() to free all fragments. The
kfunc currently clears the XDP_FLAGS_HAS_FRAGS bit, but not
XDP_FLAGS_FRAGS_PF_MEMALLOC. So far, this has not caused a issue when
building sk_buff from xdp_buff since all readers of xdp_buff->flags
use the flag only when there are fragments. Clear the
XDP_FLAGS_FRAGS_PF_MEMALLOC bit as well to make the flags correct.

90315cd293 drm/bridge: adapt drm_bridge_add/remove() docs, mention the lingering list 
The role of drm_bridge_add/remove() is more complex now after having added
the lingering list. Update the kdoc accordingly.

Also stop mentioning the global list(s) in the first line of the docs: the
most important thing to mention here is that bridges are registered and
deregistered, lists are just the type of container used to implement such
(de)registration.

27312a8f24 drm/debugfs: show lingering bridges 
The usefulness of /sys/kernel/debug/dri/bridges is limited as it only shows
bridges between drm_bridge_add() and drm_bridge_remove(). However
refcounted bridges can stay allocated and lingering for a long time after
drm_bridge_remove(), and a memory leak due to a missing drm_bridge_put()
would not be visible in this debugfs file.

Add lingering bridges to the /sys/kernel/debug/dri/bridges output.

17805a15d1 drm/bridge: add list of removed refcounted bridges 
Between drm_bridge_add() and drm_bridge_remove() bridges are registered to
the DRM core via the global bridge_list and visible in
/sys/kernel/debug/dri/bridges. However between drm_bridge_remove() and the
last drm_bridge_put() memory is still allocated even though the bridge is
not registered, i.e. not in bridges_list, and also not visible in
debugfs. This prevents debugging refcounted bridges lifetime, especially
leaks due to a missing drm_bridge_put().

In order to allow debugfs to also show the removed bridges, move such
bridges into a new ad-hoc list until they are eventually freed.

Note this requires adding INIT_LIST_HEAD(&bridge->list) in the bridge
initialization code. The lack of such init was not exposing any bug so far,
but it would with the new code, for example when a bridge is allocated and
then freed without calling drm_bridge_add(), which is common on probe
errors.

drm_bridge_add() needs special care for bridges being added after having
been previously added and then removed.  This happens for example for many
non-DCS DSI host bridge drivers like samsung-dsim which
drm_bridge_add/remove() themselves every time the DSI device does a DSI
attaches/detach. When the DSI device is hot-pluggable this happens multiple
times in the lifetime of the DSI host bridge.  On every attach after the
first one, drm_bridge_add() finds bridge->list in the removed list, not at
the initialized state as drm_bridge_add() currently expects. Add a
list_del_init() to remove the bridge from the lingering list and bring
bridge->list back to the initialized state.

17752efeca Allwinner Device Tree changes for 6.18 
This tag contains two DT binding header changes that are shared with
 the clk tree.
 
 In this cycle we gained support for the MCU PRCM clock and reset
 controller on the A523/A527/T527 family of SoCs, the NPU which is a
 Vivante GC9000 IP block, and the NPU clock that was missing. The other
 PRCM clock controller gained default bus clock rate settings. These
 were not configured in the upstream U-boot bootloader, leading to them
 running at slower rates. The assigned rates are from the user manual.
 
 There is also a new board, the NetCube Systems Nagami SoM and two of
 its carrier boards.
 
 The A523 family development boards now have their internal RTC clocks
 configured correctly, so that the RTC does not drift wildly. The missing
 functions for the AXP717 on these boards are added. Missing reset GPIOs
 and delays for Ethernet PHYs are added. Last, the Cubie A5E now has its
 LEDs described and usable.
 
 An overlay for the Orange Pi Zero interface (addon) board was added.
 This can be used with the Orange Pi Zero and Zero Plus 2. Default audio
 routing for these two boards (to be used with the addon) were added to
 complement the overlay.

d0bf7cd5df riscv: bpf: Fix uninitialized symbol 'retval_off' 
In the __arch_prepare_bpf_trampoline() function, retval_off is only
meaningful when save_ret is true, so the current logic is correct.
However, in the original logic, retval_off is only initialized under
certain conditions; for example, in the fmod_ret logic, the compiler is
not aware that the flags of the fmod_ret program (prog) have set
BPF_TRAMP_F_CALL_ORIG, which results in an uninitialized symbol
compilation warning.

So initialize retval_off unconditionally to fix it.

Commit 40863f4d6e ("bpftool: Add support for signing BPF programs")
added new options for "bpftool prog load" and "bpftool gen skeleton".
This commit brings the relevant update to the bash completion file.

We rework slightly the processing of options to make completion more
resilient for options that take an argument.

The MR1.CKS field is 3 bits wide and all the possible values (from 0 to

upstream Linux. Take into account CKS=7 which allows setting bus

f0b5c1490a Merge branch 'bpf-allow-union-argument-in-trampoline-based-programs' 
Leon Hwang says:

====================
bpf: Allow union argument in trampoline based programs

While tracing 'release_pages' with bpfsnoop[0], the verifier reports:

The function release_pages arg0 type UNION is unsupported.

However, it should be acceptable to trace functions that have 'union'
arguments.

This patch set enables such support in the verifier by allowing 'union'
as a valid argument type.

Changes:
v3 -> v4:
* Address comments from Alexei:
  * Trim bpftrace output in patch #1 log.
  * Drop the referenced commit info and the test output in patch #2 log.

v2 -> v3:
* Address comments from Alexei:
  * Reuse the existing flag BTF_FMODEL_STRUCT_ARG.
  * Update the comment of the flag BTF_FMODEL_STRUCT_ARG.

v1 -> v2:
* Add 16B 'union' argument support in x86_64 trampoline.
* Update selftests using bpf_testmod.
* Add test case about 16-bytes 'union' argument.
* Address comments from Alexei:
  * Study the patch set about 'struct' argument support.
  * Update selftests to cover more cases.

ccb4f5d91e bpf: Allow union argument in trampoline based programs 
Currently, functions with 'union' arguments cannot be traced with
fentry/fexit:

bpftrace -e 'fentry:release_pages { exit(); }' -v

The function release_pages arg0 type UNION is unsupported.

The type of the 'release_pages' arg0 is defined as:

typedef union {
	struct page **pages;
	struct folio **folios;
	struct encoded_page **encoded_pages;
} release_pages_arg __attribute__ ((__transparent_union__));

This patch relaxes the restriction by allowing function arguments of type
'union' to be traced in verifier.

In preparation for multiple scheduler support:

- Add the @sch parameter to find_global_dsq() and refill_task_slice_dfl().

- Restructure scx_allow_ttwu_queue() and make it read scx_root into $sch.

- Make RCU protection in scx_dsq_move() and scx_bpf_dsq_move_to_local()
  explicit.

d4f7d86666 sched_ext: Drop scx_kf_exit() and scx_kf_error() 
The intention behind scx_kf_exit/error() was that when called from kfuncs,
scx_kf_exit/error() would be able to implicitly determine the scx_sched
instance being operated on and thus wouldn't need the @sch parameter passed
in explicitly. This turned out to be unnecessarily complicated to implement
and not have enough practical benefits. Replace scx_kf_exit/error() usages
with scx_exit/error() which take an explicit @sch parameter.

- Add the @sch parameter to scx_kf_allowed(), scx_kf_allowed_on_arg_tasks,
  mark_direct_dispatch() and other intermediate functions transitively.

- In callers that don't already have @sch available, grab RCU, read
  $scx_root, verify it's not NULL and use it.

In preparation for multiple scheduler support, separate out scx_kick_cpu()

Internal uses of scx_bpf_kick_cpu() are converted to scx_kick_cpu(). Where
$sch is available, it's used. In the pick_task_scx() path where no
associated scheduler can be identified, $scx_root is used directly. Note
that $scx_root cannot be NULL in this case.

7852e0fd1d tools/sched_ext: scx_qmap: Make debug output quieter by default 
scx_qmap currently outputs verbose debug messages including cgroup operations
and CPU online/offline events by default, which can be noisy during normal
operation. While the existing -P option controls DSQ dumps and event
statistics, there's no way to suppress the other debug messages.

Split the debug output controls to make scx_qmap quieter by default. The -P
option continues to control DSQ dumps and event statistics
(print_dsqs_and_events), while a new -M option controls debug messages like
cgroup operations and CPU events (print_msgs). This allows users to run
scx_qmap with minimal output and selectively enable debug information as
needed.
