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). -----BEGIN PGP SIGNATURE----- iQJGBAABCAAwFiEE4fcc61cGeeHD/fCwgsRv/nhiVHEFAmZCZd4SHHJqd0Byand5 c29ja2kubmV0AAoJEILEb/54YlRxg28P/03RJlnog56dF6Isv5m+wPf6S66aDwQ/ Dv5tUTk7Fy9JU7ICny5TMfWCwAwaxJVmZ08s/BvowQsLFUnZvuKjxjX3ALTe68GU u93wX8xN/FGSTY/SnGxwhcS12TpZ33khlM2Ci16Nlfl2RFRkA7CJsjoEpUYMNU9h 4WNS3gVRamKdrT+KHxZmJ4+ZwPxG3KOpSMgYtOW8Bg7uDTUgMzezL7au7z5YDlNd uxxWR2F/Ts0HceuYIXOIun5N+sqy9QEGHT9lJVaMYvQHzx+xUvz10nsUOpB56dZv m1CzP5IOy+JloldVEjt9BohzSlEfx4cvkqPePoToOVWlCCt++LUm2tJGEWvZU4XZ vo+9Ed3y/5Mp7ws5InSrM51PyC2l+P1Hdh6prgsoaq3XHn5b+DH0Nytly2fut9zF rKIN9xBO/UI8k7jYgB9Gk3WfekJWFu9QkA1+udzf8vmPYFyJOt1PdxBFXRy7DdpU vXF//E2SIZ428LVolHyQlUCw72ZiHuc4lV1UmqK/9s1vpfp4Ksn0ou3mZIwqfEio doI8A1GSym7a8YrnZnrHCyRNCyPj+Wmk42oIDQRGw3VEA9q4jLCSsmYwVptvQM4C tgAogbbRfbZ9hTWGhMyMM9f60oDdjbxBZ2uG607UXO/Hqz4P+C1P0I/J55Fp2OM2 B8KoOSd82URw =CzKP -----END PGP SIGNATURE----- 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.

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

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. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmZBGUITHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYod3xD/98Xa4qZN7eceyyGUhgXnPLOKQzGQ7k 7cmhsoAYjABeXLvuAvtKePL7ky7OPcqVW2E/g0+jdZuRDkRDbnVkM7CDMRTyL0/b BZLhVAXyANKjK79a5WvjL0zDasYQRQ16MQJ6TPa++mX0KhZSI7KvXWIqPWov5i02 n8UbPUraH5bJi3qGKm6u4n2261Be1gtDag0ZjmGma45/3wsn3bWPoB7iPK6qxmq3 Q7VARPXAcRp5wYACk6mCOM1dOXMUV9CgI5AUk92xGfXi4RAdsFeNSzeQWn9jHWOf CYbbJjNl4QmGP4IWmy6/Up4vIiEhUCOT2DmHsygrQTs/G+nPnMAe1qUuDuECiofj iToBL3hn1dHG8uINKOB81MJ33QEGWyYWY8PxxoR3LMTrhVpfChUlJO8T2XK5nu+i 2EA6XLtJiHacpXhn8HQam0aQN9nvi4wT1LzpkhmboyCQuXTiXuJNbyLIh5TdFa1n DzqAGhRB67z6eGevJJ7kTI1X71W0poMwYlzCU8itnLOK8np0zFQ8bgwwqm9opZGq V2eSDuZAbqXVolzmaF8NSfM+b/R9URQtWsZ8cEc+/OdVV4HR4zfeqejy60TuV/4G 39CTnn8vPBKcRSS6CAcJhKPhzIvHw4EMhoU4DJKBtwBdM58RyP9NY1wF3rIPJIGh sl61JBuYYuIZXg== =bqLN -----END PGP SIGNATURE----- Merge tag 'x86-irq-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 interrupt handling updates from Thomas Gleixner: "Add support for posted interrupts on bare metal.

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 -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmZBCM0THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoeZHEACqMLN3K+1HyWflYtcTHJeYCjZLHS77 2tQeKaaskOA4W6dcGXPxMw5CHqAobHVQQMqgcJxhUdqQiOJnFFnrtCD7JtqM0hWK UORNbyeovuhAo+iJ0fTuS8p63H7vm2GIWwBLWJnOuChYv/6Yyx5Cald1skvyvbzL zePhiiAf5mkdmJMeT5wJSCqEWSRYOXsVAJ/0YAwFG3bKkJH3bmDo6SDJY02sXT5P pjbtD/0hum9wIVT4fNdYleHHQMdBdj9dLlcxXBikHq50mDMw7GxvjKiLcXmoerw3 rEBfVVJp3qpSofpNJZ3HH0ywcF3yUzq04/LPE9Tk2MoQ8NF0GzP8r9Ahke4B7cUj FysWNiAlC2IisEi6th313FZkTLx0zgewdsdEBTLt8eAE9TU0wamRbo99LZ8i/Qr3 hk7jV8DzL+EDQJLgl4p1iPJgA708eW17tbCxLEa15VKVV6P58miohmhx/IfPO2Gx FV1PPehtItsmiK/UoRtUCoFdFsqNQtOE+h8DWLyy8RDmhBqGbn9Ut4euXiQIF+rX WJKPFfslCTR39BrBcZnZeNsgOCN7tEfFRstzjzkey1DaeTGWtxmA5UGhpC2vT74y YyXluvZlgKr4S64ABmcqQj++hQLho0OQAih3uW5YVxt4VxEUcXYMJOsV1AQGpMjF UnewWH5opBQdfw== =jFLf -----END PGP SIGNATURE----- Merge tag 'irq-core-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull interrupt subsystem updates from Thomas Gleixner: "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.

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. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmZBErUTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoZVhD/9iUPzcGNgqGqcO1bXy6dH4xLpeec6o 2En1vg45DOaygN7DFxkoei20KJtfdFeaaEDH8UqmOfPcpLIuVAd0yqhgDQtx6ZcO XNd09SFDInzUt1Ot/WcoXp5N6Wt3vyEgUAlIN1fQdbaZ3fh6OhGhXXCRfiRCGXU1 ea2pSunLuRf1pKU0AYhGIexnZMOHC4NmVXw/m+WNw5DJrmWB+OaNFKfMoQjtQ1HD Vgyr2RALHnIeXm60y2j3dD7TWGXICE/edzOd7pEyg5LFXsmcp388eu/DEdOq3OTV tsHLgIi05GJym3dykPBVwZk09M5oVNNfkg9zDxHWhSLkEJmc4QUaH3dgM8uBoaRW pS3LaO3ePxWmtAOdSNKFY6xnl6df+PYJoZcIF/GuXgty7im+VLK9C4M05mSjey00 omcEywvmGdFezY6D9MmjjhFa+q2v9zpRjFpCWaIv3DQdAaDPrOzBk4SSqHZOV4lq +hp7ar1mTn1FPrXBouwyOgSOUANISV5cy/QuwOtrVIuVR4rWFVgfWo/7J32/q5Ik XBR0lTdQy1Biogf6xy0HCY+4wItOLTqEXXqeknHSMJpDzj5uZglZemgKbix1wVJ9 8YlD85Q7sktlPmiLMKV9ra0MKVyXDoIrgt4hX98A8M12q9bNdw23x0p0jkJHwGha ZYUyX+XxKgOJug== =pL+S -----END PGP SIGNATURE----- Merge tag 'timers-core-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timers and timekeeping updates from Thomas Gleixner: "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.

eventfs: Fix a possible null pointer dereference in eventfs_find_events()
In function eventfs_find_events,there is a potential null pointer
that may be caused by calling update_events_attr which will perform
some operations on the members of the ei struct when ei is NULL.
Hence,When ei->is_freed is set,return NULL directly.

ftrace: Fix possible use-after-free issue in ftrace_location()
KASAN reports a bug:
BUG: KASAN: use-after-free in ftrace_location+0x90/0x120
Read of size 8 at addr ffff888141d40010 by task insmod/424

entry_SYSCALL_64_after_hwframe+0x71/0x79
The root cause is that, in lookup_rec(), ftrace record of some address
is being searched in ftrace pages of some module, but those ftrace pages
at the same time is being freed in ftrace_release_mod() as the
corresponding module is being deleted:
CPU1 | CPU2
register_kprobes() { | delete_module() {
check_kprobe_address_safe() { |
arch_check_ftrace_location() { |
ftrace_location() { |
lookup_rec() // USE! | ftrace_release_mod() // Free!
To fix this issue:
1. Hold rcu lock as accessing ftrace pages in ftrace_location_range();
2. Use ftrace_location_range() instead of lookup_rec() in
ftrace_location();
3. Call synchronize_rcu() before freeing any ftrace pages both in
ftrace_process_locs()/ftrace_release_mod()/ftrace_free_mem().

If hdev->le_num_of_adv_sets is set to 1 it means that only handle 0x00
can be used, but since the MGMT interface instances start from 1
(instance 0 means all instances in case of MGMT_OP_REMOVE_ADVERTISING)
the code needs to map the instance to handle otherwise users will not be
able to advertise as instance 1 would attempt to use handle 0x01.

Bluetooth: L2CAP: Fix div-by-zero in l2cap_le_flowctl_init()
l2cap_le_flowctl_init() can cause both div-by-zero and an integer
overflow since hdev->le_mtu may not fall in the valid range.
Move MTU from hci_dev to hci_conn to validate MTU and stop the connection
process earlier if MTU is invalid.
Also, add a missing validation in read_buffer_size() and make it return
an error value if the validation fails.
Now hci_conn_add() returns ERR_PTR() as it can fail due to the both a
kzalloc failure and invalid MTU value.

LE Create Connection command timeout increased to 20 secs
On our DUT, we can see that the host issues create connection cancel command after 4-sec if there is no connection complete event for LE create connection cmd. As per core spec v5.3 section 7.8.5, advertisement interval range is- Advertising_Interval_Min Default : 0x0800(1.28s) Time Range: 20ms to 10.24s Advertising_Interval_Max Default : 0x0800(1.28s) Time Range: 20ms to 10.24s If the remote device is using adv interval of > 4 sec, it is difficult to make a connection with the current timeout value. Also, with the default interval of 1.28 sec, we will get only 3 chances to capture the adv packets with the 4 sec window. Hence we want to increase this timeout to 20sec.

dt-bindings: net: bluetooth: Add MediaTek MT7921S SDIO Bluetooth
The MediaTek MT7921S is a WiFi/Bluetooth combo chip that works over SDIO. WiFi and Bluetooth are separate SDIO functions within the chip. While the Bluetooth SDIO function is fully discoverable, the chip has a pin that can reset just the Bluetooth core, as opposed to the full chip. This should be described in the device tree. Add a device tree binding for the Bluetooth SDIO function of the MT7921S specifically to document the reset line. This binding is based on the MMC controller binding, which specifies one device node per SDIO function.

Bluetooth: compute LE flow credits based on recvbuf space
Previously LE flow credits were returned to the
sender even if the socket's receive buffer was
full. This meant that no back-pressure
was applied to the sender, thus it continued to
send data, resulting in data loss without any
error being reported. Furthermore, the amount
of credits was essentially fixed to a small
amount, leading to reduced performance.
This is fixed by computing the number of returned
LE flow credits based on the estimated available
space in the receive buffer of an L2CAP socket.
Consequently, if the receive buffer is full, no
credits are returned until the buffer is read and
thus cleared by user-space.
Since the computation of available receive buffer
space can only be performed approximately (due to
sk_buff overhead) and the receive buffer size may
be changed by user-space after flow credits have
been sent, superfluous received data is temporary
stored within l2cap_pinfo. This is necessary
because Bluetooth LE provides no retransmission
mechanism once the data has been acked by the
physical layer.
If receive buffer space estimation is not possible
at the moment, we fall back to providing credits
for one full packet as before. This is currently
the case during connection setup, when MPS is not
yet available.
