Having the exec queue snapshot inside a "GuC CT" section was always
wrong. Commit c28fd6c358db ("drm/xe/devcoredump: Improve section
headings and add tile info") tried to fix that bug, but with that also
broke the mesa tool that parses the devcoredump, hence it was reverted
in commit a53da2fb25a3 ("drm/xe: Revert some changes that break a mesa
debug tool").
With the mesa tool also fixed, this can propagate as a fix on both
kernel and userspace side to avoid unnecessary headache for a debug
feature.

We rely on stream->pollin to decide whether or not to block during
poll/read calls. However, currently there are blocking read code paths
which don't even set stream->pollin. The best place to consistently set
stream->pollin for all code paths is therefore to set it in
xe_oa_buffer_check_unlocked.

[WHY]
When the system powers up eDP with external monitors in seamless boot
sequence, stutter get enabled before TTU and HUBP registers being
programmed, which resulting in underflow.
[HOW]
Enable TTU in hubp_init.
Change the sequence that do not perpare_bandwidth and optimize_bandwidth
while having seamless boot streams.

[WHAT & HOW]
hpo_stream_to_link_encoder_mapping has size MAX_HPO_DP2_ENCODERS(=4),
but location can have size up to 6. As a result, it is necessary to
check location against MAX_HPO_DP2_ENCODERS.
Similiarly, disp_cfg_stream_location can be used as an array index which
should be 0..5, so the ASSERT's conditions should be less without equal.

Pull timer fixes from Thomas Gleixner:
- Properly cast the input to secs_to_jiffies() to unsigned long as
otherwise the result uses the data type of the input variable, which
causes result range checks to fail if the input data type is signed
and smaller than unsigned long.
- Handle late armed hrtimers gracefully on CPU hotplug
There are legitimate cases where a hrtimer is (re)armed on an
outgoing CPU after the timers have been migrated away. This triggers
warnings and caused people to implement horrible workarounds in RCU.
But those workarounds are incomplete and do not cover e.g. the
scheduler hrtimers.
Stop this by force moving timer which are enqueued on the current CPU
after timer migration to be queued on a remote online CPU.
This allows to undo the workarounds in a seperate step.
- Demote a warning level printk() to info level in the clocksource
watchdog code as there is no point to emit a warning level message
for a purely informational message.
- Mark a helper function __always_inline and move it into the existing
#ifdef block to avoid 'unused function' warnings from CLANG

Pull irq fixes from Thomas Gleixner:
- Ensure ordering of memory and device I/O for IPIs on RISCV
The RISCV interrupt controllers use writel_relaxed() for generating
an IPI. That's a device I/O write which is not guaranteed to be
ordered against preceding memory writes. As a consequence a IPI
receiving CPU might not be able to observe the actual IPI data which
is required to handle it. Switch to writel() which contains the
necessary memory barriers to enforce ordering.
- Fix up the fallout of the MSI conversion in the MVEVBU ICU driver.
The conversion failed to handle the change of the data storage and
kept the original code which uses the domain::host_data pointer
unchanged. After the conversion domain::host_data points to the new
msi_domain_info structure and not longer to the MVEBU specific MSI
data, which is now stored in a member of msi_domain_info. This leads
to malfunction of the transalate() callback.
- Only handle the PMC in FIQ mode when it is configured that way.
The original check was incorrect as it did not explicitely check for
the proper conditions, which led to malfunctions of the PMU
interrupt.
- Improve Kconfig dependencies for the LAN966x Outband Interrupt
controller to avoid pointless pronmpts.

While the MIDI jacks are configured correctly, and the MIDIStreaming
endpoint descriptors are filled with the correct information,
bNumEmbMIDIJack and bLength are set incorrectly in these descriptors.
This does not matter when the numbers of in and out ports are equal, but
when they differ the host will receive broken descriptors with
uninitialized stack memory leaking into the descriptor for whichever
value is smaller.
The precise meaning of "in" and "out" in the port counts is not clearly
defined and can be confusing. But elsewhere the driver consistently
uses this to match the USB meaning of IN and OUT viewed from the host,
so that "in" ports send data to the host and "out" ports receive data
from it.

In dwc2_hsotg_udc_start(), e.g. when binding composite driver, "of_node"
is set to hsotg->dev->of_node.
It causes errors when binding the gadget driver several times, on
stm32mp157c-ev1 board. Below error is seen:
"pin PA10 already requested by 49000000.usb-otg; cannot claim for gadget.0"
The first time, no issue is seen as when registering the driver, of_node
isn't NULL:
-> gadget_dev_desc_UDC_store
-> usb_gadget_register_driver_owner
-> driver_register
...
-> really_probe -> pinctrl_bind_pins (no effect)
Then dwc2_hsotg_udc_start() sets of_node.
The second time (stop the gadget, reconfigure it, then start it again),
of_node has been set, so the probing code tries to acquire pins for the
gadget. These pins are hold by the controller, hence the error.
So clear gadget.dev.of_node in udc_stop() routine to avoid the issue.

retries
The current implementation sets the wMaxPacketSize of bulk in/out
endpoints to 1024 bytes at the end of the f_midi_bind function. However,
in cases where there is a failure in the first midi bind attempt,
consider rebinding. This scenario may encounter an f_midi_bind issue due
to the previous bind setting the bulk endpoint's wMaxPacketSize to 1024
bytes, which exceeds the ep->maxpacket_limit where configured dwc3 TX/RX
FIFO's maxpacket size of 512 bytes for IN/OUT endpoints in support HS
speed only.
Here the term "rebind" in this context refers to attempting to bind the
MIDI function a second time in certain scenarios. The situations where
rebinding is considered include:
* When there is a failure in the first UDC write attempt, which may be
caused by other functions bind along with MIDI.
* Runtime composition change : Example : MIDI,ADB to MIDI. Or MIDI to
MIDI,ADB.
This commit addresses this issue by resetting the wMaxPacketSize before
endpoint claim. And here there is no need to reset all values in the usb
endpoint descriptor structure, as all members except wMaxPacketSize and
bEndpointAddress have predefined values.
This ensures that restores the endpoint to its expected configuration,
and preventing conflicts with value of ep->maxpacket_limit. It also
aligns with the approach used in other function drivers, which treat
endpoint descriptors as if they were full speed before endpoint claim.

atomic context
The following bug report happened with a PREEMPT_RT kernel:
BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48

clocksource_verify_percpu.part.0+0x6b/0x330
clocksource_watchdog_kthread+0x193/0x1a0
It is due to the fact that clocksource_verify_choose_cpus() is invoked with
preemption disabled. This function invokes get_random_u32() to obtain
random numbers for choosing CPUs. The batched_entropy_32 local lock and/or
the base_crng.lock spinlock in driver/char/random.c will be acquired during
the call. In PREEMPT_RT kernel, they are both sleeping locks and so cannot
be acquired in atomic context.
Fix this problem by using migrate_disable() to allow smp_processor_id() to
be reliably used without introducing atomic context. preempt_disable() is
then called after clocksource_verify_choose_cpus() but before the
clocksource measurement is being run to avoid introducing unexpected
latency.

The scale() functions detects invalid parameters, but continues
its calculations anyway. This causes bad results if negative values
are used for unsigned operations. Worst case, a division by 0 error
will be seen if source_min == source_max.
On top of that, after v6.13, the sequence of WARN_ON() followed by clamp()
may result in a build error with gcc 13.x.

include/linux/compiler_types.h:542:45: error:

This happens if the compiler decides to rearrange the code as follows.
if (source_min > source_max) {
WARN(..);
/* Do the clamp() knowing that source_min > source_max */
source_val = clamp(source_val, source_min, source_max);
} else {
/* Do the clamp knowing that source_min <= source_max */
source_val = clamp(source_val, source_min, source_max);
}
Fix the problem by evaluating the return values from WARN_ON and returning
immediately after a warning. While at it, fix divide by zero error seen
if source_min == source_max.

Currently we support Adaptive sync operation mode with dynamic frame
rate, but instead the operation mode with fixed rate is set.
This was initially set correctly in the earlier version of changes but
later got changed, while defining a macro for the same.

After the context is unpinned the backing memory can also be unpinned,
so any accesses via the lrc_reg_state pointer can end up in unmapped
memory. To avoid that, make sure to only access that memory if the

I'm seeing underruns with these 64bpp YUV formats on TGL.
The weird details:
- only happens on pipe B/C/D SDR planes, pipe A SDR planes
seem fine, as do all HDR planes
- somehow CDCLK related, higher CDCLK allows for bigger plane
with these formats without underruns. With 300MHz CDCLK I
can only go up to 1200 pixels wide or so, with 650MHz even
a 3840 pixel wide plane was OK
- ICL and ADL so far appear unaffected
So not really sure what's the deal with this, but bspec does
state "64-bit formats supported only on the HDR planes" so
let's just drop these formats from the SDR planes. We already
disallow 64bpp RGB formats.

When converting to folios the cleanup path of shmem_get_pages() was
missed. When a DMA remap fails and the max segment size is greater than
PAGE_SIZE it will attempt to retry the remap with a PAGE_SIZEd segment
size. The cleanup code isn't properly using the folio apis and as a
result isn't handling compound pages correctly.
v2 -> v3:
(Ville) Just use shmem_sg_free_table() as-is in the failure path of
shmem_get_pages(). shmem_sg_free_table() will clear mapping unevictable
but it will be reset when it retries in shmem_sg_alloc_table().
v1 -> v2:
(Ville) Fixed locations where we were not clearing mapping unevictable.

When running igt@gem_exec_balancer@individual for multiple iterations,
it is seen that the delta busyness returned by PMU is 0. The issue stems
from a combination of 2 implementation specific details:
1) gt_park is throttling __update_guc_busyness_stats() so that it does
not hog PCI bandwidth for some use cases. (Ref: 59bcdb564b3ba)
2) busyness implementation always returns monotonically increasing
counters. (Ref: cf907f6d29421)
If an application queried an engine while it was active,
engine->stats.guc.running is set to true. Following that, if all PM
wakeref's are released, then gt is parked. At this time the throttling
of __update_guc_busyness_stats() may result in a missed update to the
running state of the engine (due to (1) above). This means subsequent
calls to guc_engine_busyness() will think that the engine is still
running and they will keep updating the cached counter (stats->total).
This results in an inflated cached counter.
Later when the application runs a workload and queries for busyness, we
return the cached value since it is larger than the actual value (due to
(2) above)
All subsequent queries will return the same large (inflated) value, so
the application sees a delta busyness of zero.
Fix the issue by resetting the running state of engines each time
intel_guc_busyness_park() is called.
v2: (Rodrigo)
- Use the correct tag in commit message
- Drop the redundant wakeref check in guc_engine_busyness() and update
commit message

Creation of a module which contains gateway configuration consists of
few additional steps, namely:
- assigning ID (node_id) for the gateway
- attaching hardware configuration from the NHLT table (optional)
