5091cdec56 dm: change max_io_len() to use blk_max_size_offset()
Using blk_max_size_offset() enables DM core's splitting to impose
ti->max_io_len (via q->limits.chunk_sectors) and also fallback to
respecting q->limits.max_sectors if chunk_sectors isn't set.

882ec4e609 dm table: stack 'chunk_sectors' limit to account for target-specific splitting
If target set ti->max_io_len it must be used when stacking
DM device's queue_limits to establish a 'chunk_sectors' that is
compatible with the IO stack.

By using lcm_not_zero() care is taken to avoid blindly overriding the
chunk_sectors limit stacked up by blk_stack_limits().

The port mask width was larger than the actual number of ports, and
therefore, all fields following this one were also shifted by the number
of excess bits. But the driver doesn't use the REW_OP, SMAC_REPLACE_ENA

macro HNS3_MAX_NON_TSO_BD_NUM with the queried value, and rewrite

BD number of non TSO packet.

Also, add a new parameter max_non_tso_bd_num to function
hns3_tx_bd_num() and hns3_skb_need_linearized(), then they can get
the maximum BD number of non TSO packet from the caller instead of
calculating by themself, The note of hns3_skb_need_linearized()

12a6727dee drm/amd/powerplay: add one sysfs file to support the feature to modify gfx clock on Raven/Raven2/Picasso APU.
This patch is to add one sysfs file -- "pp_od_clk_voltage" for
Raven/Raven2/Picasso APU, which is only used by dGPU like VEGA10.
This sysfs file supports the feature to modify gfx engine clock(Mhz units), it can
be used to configure the min value and the max value for gfx clock limited in the
safe range.

Command guide:
echo "s level clock" > pp_od_clk_voltage
	s - adjust teh sclk level
	level - 0 or 1, "0" represents the min value, "1" represents the max value
	clock - the clock value(Mhz units), like 400, 800 or 1200, the value must be within the
                OD_RANGE limits.
Example:
$ cat pp_od_clk_voltage
OD_SCLK:
0:        200Mhz
1:       1400Mhz
OD_RANGE:
SCLK:     200MHz       1400MHz

$ echo "s 0 600" > pp_od_clk_voltage
$ echo "s 1 1000" > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0:        600Mhz
1:       1000Mhz

93b8713d61 Merge branch 'bpf: Support multi-attach for freplace'
Toke Høiland-Jørgensen says:

====================
This series adds support attaching freplace BPF programs to multiple targets.
This is needed to support incremental attachment of multiple XDP programs using
the libxdp dispatcher model.

Patch 1 moves prog_aux->linked_prog and the trampoline to be embedded in
bpf_tracing_link on attach, and freed by the link release logic, and introduces
a mutex to protect the writing of the pointers in prog->aux.

Based on this refactoring (and previously applied patches), it becomes pretty
straight-forward to support multiple-attach for freplace programs (patch 2).
This is simply a matter of creating a second bpf_tracing_link if a target is
supplied. However, for API consistency with other types of link attach, this
option is added to the BPF_LINK_CREATE API instead of extending
bpf_raw_tracepoint_open().

Patch 3 is a port of Jiri Olsa's patch to support fentry/fexit on freplace
programs. His approach of getting the target type from the target program
reference no longer works after we've gotten rid of linked_prog (because the
bpf_tracing_link reference disappears on attach). Instead, we used the saved
reference to the target prog type that is also used to verify compatibility on
secondary freplace attachment.

Patch 4 is the accompanying libbpf update, and patches 5-7 are selftests: patch
5 tests for the multi-freplace functionality itself; patch 6 is Jiri's previous
selftest for the fentry-to-freplace fix; patch 7 is a test for the change
introduced in the previously-applied patches, blocking MODIFY_RETURN functions
from attaching to other BPF programs.

With this series, libxdp and xdp-tools can successfully attach multiple programs
one at a time. To play with this, use the 'freplace-multi-attach' branch of
xdp-tools:

$ git clone --recurse-submodules --branch freplace-multi-attach https://github.com/xdp-project/xdp-tools
$ cd xdp-tools/xdp-loader
$ make
$ sudo ./xdp-loader load veth0 ../lib/testing/xdp_drop.o
$ sudo ./xdp-loader load veth0 ../lib/testing/xdp_pass.o
$ sudo ./xdp-loader status

The series is also available here:
https://git.kernel.org/pub/scm/linux/kernel/git/toke/linux.git/log/?h=bpf-freplace-multi-attach-alt-10

Stanislaw Kardach says:

====================
octeontx2-af: cleanup and extend parser config

Current KPU configuration data is spread over multiple files which makes
it hard to read. Clean this up by gathering all configuration data in a
single structure and also in a single file (npc_profile.h). This should
increase the readability of KPU handling code (since it always
references same structure), simplify updates to the CAM key extraction
code and allow abstracting out the configuration source.
Additionally extend and fix the parser config to support additional DSA
types, NAT-T-ESP and IPv6 fields.

Patch 1 ensures that CUSTOMx LTYPEs are not aliased with meaningful
LTYPEs where possible.

Patch 2 gathers all KPU profile related data into a single struct and
creates an adapter structure which provides an interface to the KPU
profile for the octeontx2-af driver.

Patches 3-4 add support for Extended DSA, eDSA and Forward DSA.

Patches 5-6 adds IPv6 fields to CAM key extraction and optimize the
parser performance for fragmented IPv6 packets.

Patch 7 refactors ESP handling in the parser to support NAT-T-ESP.

8cfae0b5fa octeontx2-af: fix Extended DSA and eDSA parsing
KPU profile interpret Extended DSA and eDSA by looking source dev. This
was incorrect and it restricts to use few source device ids and also
created confusion while parsing regular DSA tag. With below patch lookup
was based on bit 12 of Word0. This is always zero for DSA tag and it
should be one for Extended DSA and eDSA.

This tag don't have a tpid field.

This patch provides parser and extraction support for the same.
Default ldata extraction profile added for FDSA such that Src_port
is extracted and placed inplace of vlanid field. Like extended DSA
and eDSA tags,a special PKIND of 62 is used for this tag.

42006910b5 octeontx2-af: cleanup KPU config data
Refactor KPU related NPC code gathering all configuration data in a
structured format and putting it in one place (npc_profile.h).
This increases readability and makes it easier to extend the profile
configuration (as opposed to jumping between multiple header and source
files).

To do this:
* Gather all KPU profile related data into a single adapter struct.
* Convert the built-in MKEX definition to a structured one to streamline
  the MKEX loading.
* Convert LT default register configuration into a structure, keeping
  default protocol settings in same file where identifiers for those
  protocols are defined.
* Add a single point for KPU profile loading, so that its source may
  change in the future once proper interfaces for loading such config
  are in place.

450f0b9788 octeontx2-af: fix LD CUSTOM LTYPE aliasing
Since LD contains LTYPE definitions tweaked toward efficient
NIX_AF_RX_FLOW_KEY_ALG(0..31)_FIELD(0..4) usage, the original location
of NPC_LT_LD_CUSTOM0/1 was aliased with MPLS_IN_* definitions.
Moving custom frame to value 6 and 7 removes the aliasing at the cost of
custom frames being also considered when TCP/UDP RSS algo is configured.

However since the goal of CUSTOM frames is to classify them to a
separate set of RQs, this cost is acceptable.

72e71a82d6 drm/amdgpu: add new trace event for page table update
This patch adds a new trace event to track the PTE update
events. This specific event will provide information like:
- start and end of virtual memory mapping
- HW engine flags for the map
- physical address for mapping

This will be particularly useful for memory profiling tools
(like RMV) which are monitoring the page table update events.

V2: Added physical address lookup logic in trace point
V3: switch to use __dynamic_array
    added nptes int the TPprint arguments list
    added page size in the arg list
V4: Addressed Christian's review comments
    add start/end instead of seg
    use incr instead of page_sz to be accurate
V5: Addressed Christian's review comments:
    add pid and vm context information in the event
V6: Re-sequence the variables (put pid and ctx_id first)

3514521ccb drm/amdgpu: restore proper ref count in amdgpu_display_crtc_set_config
A recent attempt to fix a ref count leak in
amdgpu_display_crtc_set_config() turned out to be doing too much and
"fixed" an intended decrease as if it were a leak. Undo that part to
restore the proper balance. This is the very nature of this function
to increase or decrease the power reference count depending on the
situation.

Consequences of this bug is that the power reference would
eventually get down to 0 while the display was still in use,
resulting in that display switching off unexpectedly.
