x86/microcode/AMD: Fix __apply_microcode_amd()'s return value
When verify_sha256_digest() fails, __apply_microcode_amd() should propagate
the failure by returning false (and not -1 which is promoted to true).

net/mlx5e: SHAMPO, Make reserved size independent of page size
When hw-gro is enabled, the maximum number of header entries that are
needed per wqe (hd_per_wqe) is calculated based on the size of the
reservations among other parameters.
Miscalculation of the size of reservations leads to incorrect
calculation of hd_per_wqe as 0, particularly in the case of large page
size like in aarch64, this prevents the SHAMPO header from being
correctly initialized in the device, ultimately causing the following
cqe err that indicates a violation of PD.
mlx5_core 0000:00:08.0 eth2: ERR CQE on RQ: 0x1180
mlx5_core 0000:00:08.0 eth2: Error cqe on cqn 0x510, ci 0x0, qn 0x1180, opcode 0xe, syndrome 0x4, vendor syndrome 0x32
00000000: 00 00 00 00 04 4a 00 00 00 00 00 00 20 00 93 32
00000010: 55 00 00 00 fb cc 00 00 00 00 00 00 07 18 00 00

00000030: 00 00 00 9a 93 00 32 04 00 00 00 00 00 00 da e1
Use the correct formula for calculating the size of reservations,
precisely it shouldn't be dependent on page size, instead use the
correct multiply of MLX5E_SHAMPO_WQ_BASE_RESRV_SIZE.

net: mana: Switch to page pool for jumbo frames
Frag allocators, such as netdev_alloc_frag(), were not designed to
work for fragsz > PAGE_SIZE.
So, switch to page pool for jumbo frames instead of using page frag
allocators. This driver is using page pool for smaller MTUs already.

dm-verity: support block number limits for different ioprio classes
Calling verity_verify_io in bh for IO of all sizes is not suitable for embedded devices. From our tests, it can improve the performance of 4K synchronise random reads. For example: ./fio --name=rand_read --ioengine=psync --rw=randread --bs=4K \ --direct=1 --numjobs=8 --runtime=60 --time_based --group_reporting \ --filename=/dev/block/mapper/xx-verity But it will degrade the performance of 512K synchronise sequential reads on our devices. For example: ./fio --name=read --ioengine=psync --rw=read --bs=512K --direct=1 \ --numjobs=8 --runtime=60 --time_based --group_reporting \ --filename=/dev/block/mapper/xx-verity A parameter array is introduced by this change. And users can modify the default config by /sys/module/dm_verity/parameters/use_bh_bytes. The default limits for NONE/RT/BE is set to 8192. The default limits for IDLE is set to 0. Call verity_verify_io directly when verity_end_io is not in hardirq. Signed-off-by: LongPing Wei <weilongping@oppo.com> Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> |

drm/i915/selftests: Refactor RC6 power measurement and error handling
Revise the power measurement logic to save and evaluate energy values. Previously, the test only checked whether the system had entered the RC6 state, without considering any potential interruptions in that state. This update introduces a threshold check to ensure that the GPU remains in the RC6 state properly during the specified sleep duration. v3: - Reorder threshold check (Badal) v4: - Improved commit message (Anshuman) v5: - Rename variables for improved readability (Anshuman) Signed-off-by: Sk Anirban <sk.anirban@intel.com> Reviewed-by: Badal Nilawar <badal.nilawar@intel.com> Signed-off-by: Anshuman Gupta <anshuman.gupta@intel.com> Link: https://lore.kernel.org/r/20250327191924.4131598-1-sk.anirban@intel.com |

drm/virtio: Add capset definitions to UAPI
Since the context-type additions to the virtio-gpu spec, these have been defined locally in guest user-space, and virtio-gpu backend library code. Now, these capsets have been stabilized, and should be defined in a common space, in both the virtio_gpu header, and alongside the virtgpu_drm interface that they apply to.

ksmbd: fix r_count dec/increment mismatch
r_count is only increased when there is an oplock break wait,
so r_count inc/decrement are not paired. This can cause r_count

tracing tooling updates for 6.15:
- Allow RTLA to collect data via BPF The current implementation of rtla uses libtracefs and libtraceevent to pull sample events generated by the timerlat tracer from the trace buffer. rtla then processes the sample by updating the histogram and summary (current, maximum, minimum, and sum values) as well as checks if tracing has been stopped due to threshold overflow. In use cases where a large number of samples is being generated, that is, with measurements running on many CPUs and with a low interval, this sample processing design causes a significant CPU load on the rtla side. Furthermore, with >100 CPUs and 100us interval, rtla was reported as not being able to keep up with the samples and dropping most of them, leading to it being unusable. Change the way the timerlat trace processes samples by attaching a BPF program to the trace event using the BPF skeleton feature of bpftool. Unlike the current implementation, the BPF implementation does not check whether tracing is stopped (in BPF mode, tracing is always off to improve performance), but waits for a write to a BPF ringbuffer instead. This allows rtla to exit immediately when a threshold is violated, without waiting for the next iteration of the while loop. If the requirements for the BPF implementation are not met, either at build time or at run time, the current implementation is used as fallback. Which implementation is being used can be seen when running rtla timerlat with "-D" option. rtla can be forced to run in non-BPF mode by setting the RTLA_NO_BPF option to 1, for debugging purposes. - Fix LD_FLAGS from being dropped in build - Refactor code to remove duplication of save_trace_to_file - Always set options and do not rely on default settings Do not rely on the default kernel settings of the tracers when starting. They could have been changed by the user which gives inconsistent results.

tracing updates for v6.15:
- Add option traceoff_after_boot In order to debug kernel boot, it sometimes is helpful to enable tracing via the kernel command line. Unfortunately, by the time the login prompt appears, the trace is overwritten by the init process and other user space start up applications. Adding a "traceoff_after_boot" will disable tracing when the kernel passes control to init which will allow developers to be able to see the traces that occurred during boot. - Clean up the mmflags macros that display the GFP flags in trace events The macros to print the GFP flags for trace events had a bit of duplication. The code was restructured to remove duplication and in the process it also adds some flags that were missed before. - Removed some dead code and scripts/draw_functrace.py draw_functrace.py hasn't worked in years and as nobody complained about it, remove it. - Constify struct event_trigger_ops The event_trigger_ops is just a structure that has function pointers that are assigned when the variables are created.

Latency tracing changes for v6.15:
- Add some trace events to osnoise and timerlat sample generation
This adds more information to the osnoise and timerlat tracers as well as
allows BPF programs to be attached to these locations to extract even more
data.
- Fix to DECLARE_TRACE_CONDITION() macro
It wasn't used but now will be and it happened to be broken causing the
build to fail.
- Add scheduler specification monitors to runtime verifier (RV)
This is a continuation of Daniel Bristot's work.
RV allows monitors to run and react concurrently. Running the cumulative
model is equivalent to running single components using the same
reactors, with the advantage that it's easier to point out which
specification failed in case of error.
This update introduces nested monitors to RV, in short, the sysfs
monitor folder will contain a monitor named sched, which is nothing but
an empty container for other monitors. Controlling the sched monitor
(enable, disable, set reactors) controls all nested monitors.
The following scheduling monitors are added:
* sco: scheduling context operations
Monitor to ensure sched_set_state happens only in thread context
* tss: task switch while scheduling
Monitor to ensure sched_switch happens only in scheduling context
* snroc: set non runnable on its own context
Monitor to ensure set_state happens only in the respective task's context
* scpd: schedule called with preemption disabled
Monitor to ensure schedule is called with preemption disabled
* snep: schedule does not enable preempt
Monitor to ensure schedule does not enable preempt
* sncid: schedule not called with interrupt disabled
Monitor to ensure schedule is not called with interrupt disabled

ftrace changes for v6.15:
- Record function parameters for function and function graph tracers
An option has been added to function tracer (func-args) and the function
graph tracer (funcgraph-args) that when set, the tracers will record the
registers that hold the arguments into each function event. On reading of
the trace, it will use BTF to print those arguments. Most archs support up
to 6 arguments (depending on the complexity of the arguments) and those
are printed. If a function has more arguments then what was recorded, the
output will end with " ... )".
Example of function graph tracer:
6) | dummy_xmit [dummy](skb = 0x8887c100, dev = 0x872ca000) {
6) | consume_skb(skb = 0x8887c100) {
6) | skb_release_head_state(skb = 0x8887c100) {
6) 0.178 us | sock_wfree(skb = 0x8887c100)
6) 0.627 us | }
- The rest of the changes are minor clean ups and fixes

wifi: ath12k: add monitor interface support on QCN9274
Currently, the monitor interface is not supported. To support the monitor interface, configure the monitor vdev state identifier, configure the HTT filter setup, subscribe the mac80211 NO_VIRTUAL_MONITOR feature, remove the VIRTUAL_MONITOR handler procedures since align to NO_VIRTUAL_MONITOR feature and prevent monitor interface to transmit packet. Therefore, add these procedures to add monitor interface support and enable the monitor interface support on the QCN9274 platform through the hardware parameter.

wifi: ath12k: Move to NO_VIRTUAL monitor
Currently, VIRTUAL monitor handling is present. In multi radio model, VIRTUAL monitor is not suitable since each radio needs a separate VIF and channel context. Therefore, switch to NO_VIRTUAL_MONITOR feature. Remove the monitor_conf_enabled flag and mac_op_config() handler as they are not need for the NO_VIRTUAL_MONITOR feature. In NO_VIRTUAL_MONITOR handling, each interface creation/deletion triggers the mac_op_add_interface() / mac_op_remove_interface() callback. Consequently, remove the monitor vdev create/delete/start/stop from the other vdev type handlers.

wifi: ath12k: Refactor the monitor channel context procedure
Currently, the monitor start procedure use the iteration callback to pick the last available channel definition in the mac80211 hardware. This approach is incorrect for the single wiphy model, as it holds multiple radio/link channel contexts within the same mac80211 hardware.

wifi: ath12k: fix NULL access in assign channel context handler
Currently, when ath12k_mac_assign_vif_to_vdev() fails, the radio handle
(ar) gets accessed from the link VIF handle (arvif) for debug logging, This
is incorrect. In the fail scenario, radio handle is NULL. Fix the NULL
access, avoid radio handle access by moving to the hardware debug logging
helper function (ath12k_hw_warn).

tracing and sorttable updates for 6.15:
- Implement arm64 build time sorting of the mcount location table When gcc is used to build arm64, the mcount_loc section is all zeros in the vmlinux elf file. The addresses are stored in the Elf_Rela location. To sort at build time, an array is allocated and the addresses are added to it via the content of the mcount_loc section as well as he Elf_Rela data. After sorting, the information is put back into the Elf_Rela which now has the section sorted. - Make sorting of mcount location table for arm64 work with clang as well When clang is used, the mcount_loc section contains the addresses, unlike the gcc build. An array is still created and the sorting works for both methods. - Remove weak functions from the mcount_loc section Have the sorttable code pass in the data of functions defined via nm -S which shows the functions as well as their sizes. Using this information the sorttable code can determine if a function in the mcount_loc section was weak and overridden. If the function is not found, it is set to be zero. On boot, when the mcount_loc section is read and the ftrace table is created, if the address in the mcount_loc is not in the kernel core text then it is removed and not added to the ftrace_filter_functions (the functions that can be attached by ftrace callbacks). - Update and fix the reporting of how much data is used for ftrace functions On boot, a report of how many pages were used by the ftrace table as well as how they were grouped (the table holds a list of sections that are groups of pages that were able to be allocated).

bcachefs updates for 6.15
On disk format is now soft frozen: no more required/automatic are
anticipated before taking off the experimental label.
Major changes/features since 6.14:
- Scrub
- Blocksize greater than page size support
- A number of "rebalance spinning and doing no work" issues have been
fixed; we now check if the write allocation will succeed in
bch2_data_update_init(), before kicking off the read.
There's still more work to do in this area. Later we may want to add
another bitset btree, like rebalance_work, to track "extents that
rebalance was requested to move but couldn't", e.g. due to destination
target having insufficient online devices.
- We can now support scaling well into the petabyte range: latest
bcachefs-tools will pick an appropriate bucket size at format time to
ensure fsck can run in available memory (e.g. a server with 256GB of
ram and 100PB of storage would want 16MB buckets).
On disk format changes:
- 1.21: cached backpointers (scalability improvement)
Cached replicas now get backpointers, which means we no longer rely on
incrementing bucket generation numbers to invalidate cached data: this
lets us get rid of the bucket generation number garbage collection,
which had to periodically rescan all extents to recompute bucket
oldest_gen.
Bucket generation numbers are now only used as a consistency check,
but they're quite useful for that.
- 1.22: stripe backpointers
Stripes now have backpointers: erasure coded stripes have their own
checksums, separate from the checksums for the extents they contain
(and stripe checksums also cover the parity blocks). This is required
for implementing scrub for stripes.
- 1.23: stripe lru (scalability improvement)
Persistent lru for stripes, ordered by "number of empty blocks". This
is used by the stripe creation path, which depending on free space
may create a new stripe out of a partially empty existing stripe
instead of starting a brand new stripe.
This replaces an in-memory heap, and means we no longer have to read
in the stripes btree at startup.
- 1.24: casefolding
Case insensitive directory support, courtesy of Valve.
This is an incompatible feature, to enable mount with
-o version_upgrade=incompatible
- 1.25: extent_flags
Another incompatible feature requiring explicit opt-in to enable.
This adds a flags entry to extents, and a flag bit that marks extents
as poisoned.
A poisoned extent is an extent that was unreadable due to checksum
errors. We can't move such extents without giving them a new checksum,
and we may have to move them (for e.g. copygc or device evacuate).
We also don't want to delete them: in the future we'll have an API
that lets userspace ignore checksum errors and attempt to deal with
simple bitrot itself. Marking them as poisoned lets us continue to
return the correct error to userspace on normal read calls.
Other changes/features:
- BCH_IOCTL_QUERY_COUNTERS: this is used by the new 'bcachefs fs top'
command, which shows a live view of all internal filesystem counters.
- Improved journal pipelining: we can now have 16 journal writes in
flight concurrently, up from 4. We're logging significantly more to
the journal than we used to with all the recent disk accounting
changes and additions, so some users should see a performance
increase on some workloads.
- BCH_MEMBER_STATE_failed: previously, we would do no IO at all to
devices marked as failed. Now we will attempt to read from them, but
only if we have no better options.
- New option, write_error_timeout: devices will be kicked out of the
filesystem if all writes have been failing for x number of seconds.
We now also kick devices out when notified by blk_holder_ops that
they've gone offline.
- Device option handling improvements: the discard option should now be
working as expected (additionally, in -tools, all device options that
can be set at format time can now be set at device add time, i.e.
data_allowed, state).
- We now try harder to read data after a checksum error: we'll do
additional retries if necessary to a device after after it gave us
data with a checksum error.
- More self healing work: the full inode <-> dirent consistency checks
that are currently run by fsck are now also run every time we do a
lookup, meaning we'll be able to correct errors at runtime. Runtime
self healing will be flipped on after the new changes have seen more
testing, currently they're just checking for consistency.
- KMSAN fixes: our KMSAN builds should be nearly clean now, which will
put a massive dent in the syzbot dashboard.

We now also kick devices out when notified by blk_holder_ops that
they've gone offline.
- Device option handling improvements: the discard option should now
be working as expected (additionally, in -tools, all device options
that can be set at format time can now be set at device add time,
i.e. data_allowed, state).
- We now try harder to read data after a checksum error: we'll do
additional retries if necessary to a device after after it gave us
data with a checksum error.
- More self healing work: the full inode <-> dirent consistency
checks that are currently run by fsck are now also run every time
we do a lookup, meaning we'll be able to correct errors at runtime.
Runtime self healing will be flipped on after the new changes have
seen more testing, currently they're just checking for consistency.
- KMSAN fixes: our KMSAN builds should be nearly clean now, which
will put a massive dent in the syzbot dashboard"
