drm/xe/uc: Move GuC submission init to post hwconfig step
We shouldn't need anything from the GuC submission code until we finish GuC initialization in post hwconfig step. While around add diagnostic message if we fail uC init.

drm/xe/uc: Reorder post hwconfig uC initialization step
We want to move the GuC submission initialization to the post hwconfig step, but now this step is done too late as migration initialization uses exec_queue that would crash due to a unset exec_queue_ops. We can easily fix that by small function reorder.

clk: samsung: Don't register clkdev lookup for the fixed rate clocks
Commit 4d11c62ca8d7 ("clkdev: report over-sized strings when creating
clkdev entries") revealed that clock lookup is registered for all fixed
clocks. The mentioned commit added a check if the registered name is not
too long. This fails for some clocks registered for Exynos542x SoCs family.
This lookup is a left-over from early common clock framework days, not
really needed nowadays, so remove it to avoid further issues.

drm/xe: Only use reserved BCS instances for usm migrate exec queue
The GuC context scheduling queue is 2 entires deep, thus it is possible
for a migration job to be stuck behind a fault if migration exec queue
shares engines with user jobs. This can deadlock as the migrate exec
queue is required to service page faults. Avoid deadlock by only using
reserved BCS instances for usm migrate exec queue.

Thermal control updates for 6.10-rc1
- Redesign the thermal governor interface to allow the governors to
work in a more straightforward way (Rafael Wysocki).
- Make thermal governors take the current trip point thresholds into
account in their computations which allows trip hysteresis to be
observed more accurately (Rafael Wysocki).
- Make the thermal core manage passive polling for thermal zones and
remove passive polling management from thermal governors (Rafael
Wysocki).
- Refactor trip point representation and move the definition of
thermal governor and thermal zone device structures to the thermal
core (Rafael Wysocki).
- Sort trip point crossing notifications and debug recording of trip
point crossing events by temperature (Rafael Wysocki).
- Improve the handling of cooling device states and thermal mitigation
episodes in progress in the thermal debug code (Rafael Wysocki).
- Avoid excessive updates of trip point statistics and clean up the
printing of thermal mitigation episode information (Rafael Wysocki).
- Clean up thermal governors and thermal core (Rafael Wysocki).
- Allow thermal drivers to register notifiers that will be invoked
on netlink events like BIND and UNBIND, so that they can adjust
their activity depending on whether or not there are any
subscribers of netlink messages coming from them, and make
the Intel HFI driver use this mechanism (Stanislaw Gruszka).
- Adjust the update delay and capabilities-per-event values in the
Intel HFI thermal driver to prevent it from missing events and allow
it to process more data in one go (Ricardo Neri).
- Add missing MODULE_DESCRIPTION() to multiple files in the
int340x_thermal and intel_soc_dts_iosf drivers (Srinivas Pandruvada).
- Replace deprecated strncpy() with strscpy() in the int340x_thermal
driver (Justin Stitt).
- Add QCM2290 compatible DT bindings for Lmh and fix a NULL pointer
dereference in the lmh driver when the SCM is not present (Konrad
Dybcio).
- Use the strreplace() function instead of doing it manually in the
Armada driver (Rasmus Villemoes).
- Convert st,stih407-thermal to DT schema and fix up missing
properties (Raphael Gallais-Pou).
- Add suspend/resume by restoring the context of the tsens sensor
(Priyansh Jain).
- Support A1 SoC family Thermal Sensor controller and add the DT
bindings (Dmitry Rokosov).
- Improve the temperature approximation calculation and consolidate
the Tj constant into a shared area of the structure instead of
duplicating it on the Rcar Gen3 (Niklas Söderlund).
- Fix the Mediatek LVTS sensor coefficient for the MT8192 in order to support
it correctly (Hsin-Te Yuan).
- Fix a NULL pointer dereference in the tsens driver when the function
compute_intercept_slope() is called with a NULL parameter (Aleksandr
Mishin).
- Remove some unused fields in struct qpnp_tm_chip and k3_bandgap
(Christophe Jaillet).
- Fix up calibration efuse data decoding, consolidate the code by
checking boundaries and refactor some part of the LVTS Mediatek
driver. After setting the scene, add MT8186 and MT8188 along with
the DT bindings (Nicolas Pitre).
- Add Loongson-2K2000 support after some minor code adjustements and
providing the DT bindings definition (Binbin Zhou).

Merge tag 'thermal-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull thermal control updates from Rafael Wysocki:
"The most significant part of this is a rework of thermal governors,
including a redesign of the thermal governor interface and changes to
make some of them take trip point hysteresis into account properly, as
well as some related cleanups of the thermal governors and thermal
core.
The above is based on preliminary changes refactoring thermal data
structures and moving the definitions of some of them into the thermal
core which also ensure that trip point crossing notifications will be
sent to user space via netlink and recorded in the debug statistics in
temperature order.
In addition, netlink bind/unbind notifications are added to the
thermal core and the Intel HFI driver is modified to use them to avoid
sending netlink messages until there are subscribers.
Apart from that, multiple thermal drivers are updated which includes
new hardware support (MediaTek MT8188 and MT8186, Amlogic A1 thermal
sensor, Loongson-2K2000, Lmh QCM2290), fixes, cleanups and
documentation updates, and the recently added thermal debug code is
fixed and cleaned up.
Specifics:
- Redesign the thermal governor interface to allow the governors to
work in a more straightforward way (Rafael Wysocki)
- Make thermal governors take the current trip point thresholds into
account in their computations which allows trip hysteresis to be
observed more accurately (Rafael Wysocki)
- Make the thermal core manage passive polling for thermal zones and
remove passive polling management from thermal governors (Rafael
Wysocki)
- Refactor trip point representation and move the definition of
thermal governor and thermal zone device structures to the thermal
core (Rafael Wysocki)
- Sort trip point crossing notifications and debug recording of trip
point crossing events by temperature (Rafael Wysocki)
- Improve the handling of cooling device states and thermal
mitigation episodes in progress in the thermal debug code (Rafael
Wysocki)
- Avoid excessive updates of trip point statistics and clean up the
printing of thermal mitigation episode information (Rafael Wysocki)
- Clean up thermal governors and thermal core (Rafael Wysocki)
- Allow thermal drivers to register notifiers that will be invoked on
netlink events like BIND and UNBIND, so that they can adjust their
activity depending on whether or not there are any subscribers of
netlink messages coming from them, and make the Intel HFI driver
use this mechanism (Stanislaw Gruszka)
- Adjust the update delay and capabilities-per-event values in the
Intel HFI thermal driver to prevent it from missing events and
allow it to process more data in one go (Ricardo Neri)
- Add missing MODULE_DESCRIPTION() to multiple files in the
int340x_thermal and intel_soc_dts_iosf drivers (Srinivas
Pandruvada)
- Replace deprecated strncpy() with strscpy() in the int340x_thermal
driver (Justin Stitt)
- Add QCM2290 compatible DT bindings for Lmh and fix a NULL pointer
dereference in the lmh driver when the SCM is not present (Konrad
Dybcio)
- Use the strreplace() function instead of doing it manually in the
Armada driver (Rasmus Villemoes)
- Convert st,stih407-thermal to DT schema and fix up missing
properties (Raphael Gallais-Pou)
- Add suspend/resume by restoring the context of the tsens sensor
(Priyansh Jain)
- Support A1 SoC family Thermal Sensor controller and add the DT
bindings (Dmitry Rokosov)
- Improve the temperature approximation calculation and consolidate
the Tj constant into a shared area of the structure instead of
duplicating it on the Rcar Gen3 (Niklas Söderlund)
- Fix the Mediatek LVTS sensor coefficient for the MT8192 in order to
support it correctly (Hsin-Te Yuan)
- Fix a NULL pointer dereference in the tsens driver when the
function compute_intercept_slope() is called with a NULL parameter
(Aleksandr Mishin)
- Remove some unused fields in struct qpnp_tm_chip and k3_bandgap
(Christophe Jaillet)
- Fix up calibration efuse data decoding, consolidate the code by
checking boundaries and refactor some part of the LVTS Mediatek
driver. After setting the scene, add MT8186 and MT8188 along with
the DT bindings (Nicolas Pitre)
- Add Loongson-2K2000 support after some minor code adjustements and
providing the DT bindings definition (Binbin Zhou)"

Merge tag 'sh-for-v6.10-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux
Pull sh updates from John Paul Adrian Glaubitz:
"The majority of improvements are coming from Geert Uytterhoeven who
took the time to fix a total of 30 cases of "-Wmissing-prototypes"
compiler warnings, either by adding a missing header include, defining
the missing forward declarations or making the functions in question
static.
In the case of several DMA functions, the fix was to actually just
remove them as they were added but never used. Another one of these
warnings was eliminated by removing the left-over sh5 cache handling
support, a change that was suggested by Yoshinori Sato and, finally,
the last of these warnings was fixed by guarding the function
setup_profiling_timer() with CONFIG_PROFILING.
While at it, Geert also removed two unneeded casts to kprobe_opcode_t
in the kprobes code.
Another change was contributed by Guenter Roeck to fix errors that
were reported during checksum unit tests. The fix actually reverts the
older change

s390/ipl: Do not accept z/VM CP diag X'008' cmds longer than max length
The old implementation of vmcmd sysfs string attributes truncated passed z/VM CP diagnose X'008' commands which were longer than the max allowed number of characters but the reported number of written characters was still equal to the entire length of a given string. This can result in silent failures of some s390-tools (e.g. dumpconf) which can be very hard to detect. Therefore, this commit makes a write attempt to a vmcmd sysfs attribute * fail with E2BIG error if a given string is longer than the maximum allowed one * never destroy the old data in the vmcmd sysfs attribute if the new data doesn't fit into it entirely * return the actual number of written characters if it succeeds Reviewed-by: Heiko Carstens <hca@linux.ibm.com> Signed-off-by: Alexander Egorenkov <egorenar@linux.ibm.com> Signed-off-by: Alexander Gordeev <agordeev@linux.ibm.com> |

s390/ipl: Fix size of vmcmd buffers for sending z/VM CP diag X'008' cmds
z/VM CP diagnose X'008' accepts commands of max 240 characters. Using a smaller value as a buffer size makes kernel send truncated CP commands which are longer than the old buffer size. This can result in invalid CP commands passed to z/VM.

X86 interrupt handling update:
Support for posted interrupts on bare metal
Posted interrupts is a virtualization feature which allows to inject
interrupts directly into a guest without host interaction. The VT-d
interrupt remapping hardware sets the bit which corresponds to the
interrupt vector in a vector bitmap which is either used to inject the
interrupt directly into the guest via a virtualized APIC or in case
that the guest is scheduled out provides a host side notification
interrupt which informs the host that an interrupt has been marked
pending in the bitmap.
This can be utilized on bare metal for scenarios where multiple
devices, e.g. NVME storage, raise interrupts with a high frequency. In
the default mode these interrupts are handles independently and
therefore require a full roundtrip of interrupt entry/exit.
Utilizing posted interrupts this roundtrip overhead can be avoided by
coalescing these interrupt entries to a single entry for the posted
interrupt notification. The notification interrupt then demultiplexes
the pending bits in a memory based bitmap and invokes the corresponding
device specific handlers.
Depending on the usage scenario and device utilization throughput
improvements between 10% and 130% have been measured.
As this is only relevant for high end servers with multiple device
queues per CPU attached and counterproductive for situations where
interrupts are arriving at distinct times, the functionality is opt-in
via a kernel command line parameter.

Updates for the interrupt subsystem:
- Core code:
- Interrupt storm detection for the lockup watchdog:
Lockups which are caused by interrupt storms are not easy to debug
because there is no information about the events which make the lockup
detector trigger.
To make this more user friendly, provide an extenstion to interrupt
statistics which allows to take snapshots and an interface to retrieve
the delta to the snapshot. Use this new mechanism in the watchdog code
to do a two stage lockup analysis by taking the snapshot and printing
the deltas for the topmost active interrupts on the second trigger.
Note: This contains both the interrupt and the watchdog changes as
the latter depend on the former obviously.
- Avoid summation loops in the /proc/interrupts output and use the global
counter when possible
- Skip suspended interrupts on CPU hotplug operations to ensure that they
are not delivered before the system resumes the device drivers when
coming out of suspend.
- On CPU hot-unplug interrupts which are affine to the outgoing CPU are
migrated to a different CPU in the affinity mask. This can fail when
the CPUs have no vectors left. Instead of giving up try to migrate it
to any online CPU and thereby breaking the affinity setting in order to
prevent a stale device interrupt which targets an offline CPU
- The usual small cleanups
- Driver code:
- Support for the RISCV AIA MSI controller
- Make the interrupt allocation for the Loongson PCH controller more
flexible to prevent vector exhaustion
- The usual set of cleanups and fixes all over the place

A single update for the TSC synchronixation sanity checks:
The sad state of TSC being notoriously non-sychronized for several decades caused the kernel to grow quite rigorous sanity checks to detect whether the TSC is valid to be used for timekeeping. The TSC ADJUST MSR provides the offset between the initial TSC value after hardware reset and later modifications. This allows to detect cases where firmware tampers with the TSC and also allows to correct the firmware induced damage by resetting the offset in a controlled way. The universal correct rule is that the TSC ADJUST value has to be consistent within all CPUs of a socket. The kernel further assumes that the TSC offset should be consistent between sockets. That's not really correct as systems with a huge number of sockets are not architecurally guaranteed to reset the per socket TSC base synchronously. In case that the per socket offset is not consistent the kernel resets it to the offset of the boot CPU and then does a synchronization check which corrects for the inter socket delays. That works most of the time, but it is suboptimal as the firmware has eventually better information about the per socket offset and on sane systems that offset should just work in the validation checks. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmZCDA4THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYodLcD/4hZmCiEL97M+qb0rjmscKmJq/EOjxm pRgT/+vH2MakYh2xIjLSeMtRB5eFdfz+ZspJGEt017yW5l+saZ6edrq+g2qi1EfJ TDGbDGK9T6HR0WDplFLqLXolKS2lcvHbolATu/t5ZQmrRmuGuS+6t6eAoI9QcaWQ DaqMtdSQNq8B5hopaZtaJSTTkznD/CtKyMCvVKGxXE2gH6d6UmezR72f6oruzgg9 WXLDt1sPxg1zl1rS1GdeRa4xXrsLxr8THZ53Nr5pPyZV6FCSOZQtcurwhsIYcMO7 b3m+LU04XGURK196c0Uej8UwRCAHpD50aS91GcclXsR4wTKyFatVz9mpwZOK/F/L Pw+5O6xUeyIAKMr6YJl6KusPhhwDcYm+ETuTzMmWMyJEh91lLYHyCKniE3wsHpzT L7er6HWOwBaPlOnvuOhl4rzqr0F+9xLmWWq6s+85HlvlgfV1NjEhqi7dn/ZO1jdx Im3Xq8sq04tIMNjLPSTkovXmvU2us45yQk2HthWSM7FQ+vpzPDgdp1sVFsLK19cu +t0jI01qSUBzYvcM28CDX99hEI2L8Oo/nC1/Vq/4MB+KkEPCUMKr0ZA2nTKHL8lx +lOGdnzokr6DsbRdtfqWKywc/is2r1OXrOSBR23SwwK1XQ2aRMi/0F96Q0cR9lzt 6utxZRFhc7BtpA== =W1qL -----END PGP SIGNATURE----- Merge tag 'x86-timers-2024-05-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 timers update from Thomas Gleixner: "A single update for the TSC synchronixation sanity checks: The sad state of TSC being notoriously non-sychronized for several decades caused the kernel to grow quite rigorous sanity checks to detect whether the TSC is valid to be used for timekeeping.

Timers and timekeeping updates:
- Core code:
- Make timekeeping and VDSO time readouts resilent against math overflow:
In guest context the kernel is prone to math overflow when the host
defers the timer interrupt due to overload, malfunction or malice.
This can be mitigated by checking the clocksource delta for the
maximum deferrement which is readily available. If that value is
exceeded then the code uses a slowpath function which can handle the
multiplication overflow.
This functionality is enabled unconditionally in the kernel, but made
conditional in the VDSO code. The latter is conditional because it
allows architectures to optimize the check so it is not causing
performance regressions.
On X86 this is achieved by reworking the existing check for negative
TSC deltas as a negative delta obviously exceeds the maximum
deferrement when it is evaluated as an unsigned value. That avoids two
conditionals in the hotpath and allows to hide both the negative delta
and the large delta handling in the same slow path.
- Add an initial minimal ktime_t abstraction for Rust
- The usual boring cleanups and enhancements
- Drivers:
- Boring updates to device trees and trivial enhancements in various
drivers.

drm/xe: Fix the warning conditions
The maximum timeout display uses in xe_pcode_request is 3 msec, add the warning in cases the function is misused with higher timeouts. Add a warning if pcode_try_request is not passed the timeout parameter greater than 0.

drm/xe: Change pcode timeout to 50msec while polling again
Polling is initially attempted with timeout_base_ms enabled for
preemption, and if it exceeds this timeframe, another attempt is made
without preemption, allowing an additional 50 ms before timing out.

- Rebase
v3
- Move warnings to separate patch (Lucas)
