KNOWN ISSUES:

- Pinephone Pro:
  - imx258 capture doesn't work after suspend/resume cycle (test)

- Pinephone:
  - You may experience p-boot display pipeline handover failures with the
    new HDMI HPD fix since (2021-10-26) if you have drivers compiled in such
    a way that parts of the sunxi DRM stack have to re-probe on boot.
    One way to workaround this is to compile everything needed for anx7688
    and display pipeline as built-in drivers.
  - Bluetooth is never powered off. Only way to power it off is to unload
    the bluetooth driver module. (rfkill or bluetoothctl power off do not
    work)

2022-11-01:
- rebased on v6.1-rc3
- add pinephone keyboard power manager driver
  - this driver manages charging cycle of both batteries and provides
    LED triggers, uevents and combined state in debugfs/kbpwr/state usable
    for summary capacity/discharge rate reporting
  - the driver optimizes for the highest power efficiency (power is used
    more directly without needless recharging of phone's battery from the
    keyboard battery)
  - the driver also performs calibration of kb battery internal resistance
    to improve reliability of capacity reporting of keyboard battery
  - the driver optionally provides emergency shutdown when both batteries
    are almost discharged
- make various PMIC drivers report battery capacity in uWh to userspace
  to make calculations for total capacity of multi-battery setup with
  different sized batteries more meaningful
- move to mainlined pinephone-keyboard driver
- ported sun6i-csi patches over to the 6.1 (base driver was changed quite
  a lot in rc2, so multicamera support needed to be rewritten from scratch)
- fixed pinephone keyboard current reporting (with large currents, the
  keyboard would sometimes report incorrect negative values due to integer
  overflow)
- renamed ppp selfie camera sensor subdevice name to be mainline compatible
- ppkb: allowed to disable special handling of FN layer via module parameter
  (to make it possible to use Fn key as another modifier key in xkb)
- hopefully final fix for quartz64-a pcie register/address ranges map
- added buffer support for af8133j magnetometer driver
- removed useless error messages
- sun4i-drm (pinephone) DRM driver fixes
  - rewritten patches that fix layer positioning and fixed additional bugs
    in the driver (reconfiguring planes while crtc was turned off led to
    corruption/stale framebuffer being scanned to the display)
- pinephone: fix power key getting stuck after resume, when pressed and
  released quickly enough (reported by Aren)

- added support for front and back camera for Pinephone Pro
- resolved clock frequency incompatibility between the sensor drivers
2022-05-21:
- rebase on v5.18-rc8
- stupid ass schematic for pinephone pro is completely confusing, which is one
  reason why world facing camera didn't work up to now. See for yourself:
  This https://megous.com/dl/tmp/39cbd011289c6818.png apparently means that
  IMX258 is connected to MIPI1_TX1/RX1 lol https://megous.com/dl/tmp/5f25b00ef0166252.png
  MIPI_RX0 is isp0 MIPI1_RX1 is isp1. Just by reading the camera sheet in the
  schematic, I happily assumed that naming signals MIPI_RX0, they actually really
  are MIPI_RX0, but alas. Anyway, I moved IMX258 sensor node in device tree
  to isp1, so that increases chances that users who have working connection
  to the sensor over I2C will have a working camera now. :) Please test and
  report back.

  (until now it was hardcoded in device tree)
  - minimum brightness calibration instructions (default for lth_brightness is 10%,
    meaning is 'PWM duty cycle at the lowest brightness setting'):

  echo 1 > /sys/class/backlight/backlight/brightness
  echo 1 > /sys/class/backlight/backlight/device/lth_brightness
  echo 2 > /sys/class/backlight/backlight/device/lth_brightness
  echo 3 > /sys/class/backlight/backlight/device/lth_brightness

- applied Samuel's time travel avoidance fix https://patchwork.kernel.org/project/linux-arm-kernel/patch/20210515021439.55316-1-samuel@sholland.org/
  - this should fix occasional stalls and system hangs
- revert fine tuned OCV based capacity reporting, PMIC is not reporting OCV correctly
  so kernel has garbage input for the OCV -> capacity conversion and thus produces
  garbage output too (this stops large jumps in capacity when plugging in a charger
  and in general makes capacity reporting saner)
- fixed "NOHZ tick-stop error: Non-RCU local softirq work is pending, handler #08!!!"
- wifi driver no longer prevents dynticks from working
- improved (well..., added) suspend/resume code to anx7688 driver :)

- rebase on 5.12 final
- fixed behavior with dumb charger (DCP) being forced to 500mA on boot from anx7688
  driver

  reducing power consumption by about 40mW in sleep (and by 130mW when touching
  the screen in sleep)
  - before: https://megous.com/dl/tmp/0533207eed42258c.png
  - after: https://megous.com/dl/tmp/5d504d680415e2e3.png
  - those power spikes are touch controller checking if there's a finger touching
    the screen, and those dense spikes are when the finger is actually touching
    the screen

- used nvmem reboot driver (suggested by Samuel in RFC patch) for rebooting to FEL,
  eMMC bootloader, various p-boot boot configs on either eMMC or SD card's bootfs filesystems,
  boot menu, etc. via reboot() syscall with extra arg (see LINUX_REBOOT_CMD_RESTART2)
  (p-boot is also updated to support this mechanism, as of 2021-02-15)
2021-02-08:

2020-12-07:
- rebased on top of 5.10-rc7
2020-12-05:
- modem power driver: add more powerup modes and change interface for dumb and fastboot powerup
  - you can now write 2, 3 or 4 to .../powered sysfs file to select differnt powerup mode from
    the normal one (1)
  - this is useful for selecting alternate userspace configurations early in boot to allow
    tracing the userspace processes from early on for reverse engineering, and in the near
    future, it will be used to switch between original and fully-FOSS userspace code
    running on the modem's APPS CPU on powerup
    - see https://xnux.eu/log/#028
2020-12-02:
- fix WiFi blocking suspend
- improve modem power driver interaction with kernel's autosleep
- shorten resume times from 1.2s to 400ms (wifi driver optimization)
2020-11-30:
- I improved the anx7688 driver to actually respect PD capabilities of the source,
  and don't overload it. This should make it more likely to work with the USB-C
  docks when docks are powered.
- Pine64 dock can provide either 500mA when powered from regular USB-A charger
  (regardless of what kind of charger it is, it can't use more current from it)
- With my 3A PD charger, Pine64 dock will advertise 2600mA and Pinephone will
  now respect this limit.
- rebase on linus/master (5.10-rc6 atm)
- increase I2C clock for sensors and touchscreen/anx7688 from 100kHz to 400kHz
- added patch from https://patchwork.kernel.org/project/dri-devel/cover/20200222024210.18697-1-yuq825@gmail.com/#23237865

My kernel's main integration branch is 'orange-pi-$VER' (this one).
No other branch is supposed to work alone. My defconfigs are tested
and work on the boards I support. Read the README.md for more info.

Only my branches based on the current mainline kernel branch are
maintained (those are usually the -rc# kernels!). You can find the
current mainline version here https://www.kernel.org/ (mainline: ...)

My prebuilt kernels can be found at https://xff.cz/kernels/ You can
use them to test that your board works, or just run them without
bothering with building everything yourself. I run them on all my
boards.

My website is https://xnux.eu and may contain useful advice.

Good luck!

KNOWN ISSUES:

- Pinephone Pro:
  - imx258 capture doesn't work after suspend/resume cycle (test)

- Pinephone:
  - You may experience p-boot display pipeline handover failures with the
    new HDMI HPD fix since (2021-10-26) if you have drivers compiled in such
    a way that parts of the sunxi DRM stack have to re-probe on boot.
    One way to workaround this is to compile everything needed for anx7688
    and display pipeline as built-in drivers.
  - Bluetooth is never powered off. Only way to power it off is to unload
    the bluetooth driver module. (rfkill or bluetoothctl power off do not
    work)

2023-02-03:
- rebased on v6.2-rc6+
2023-01-22:
- reworked multi-camera support for Pinephone on top of upstream changes
  (media device graph changed quite a bit upstream, you may need to update the
  userspace camera apps for them to continue working)
- fixed Alt-DP mode on Pinebook Pro
- rebased on v6.2-rc5+
2022-12-30:
- rebased on v6.1
- pulled in v6.1.1
2022-12-11:
- ppp: don't reset 'display state of charge' (dsoc) to 0 on vbat low interrupt
2022-12-10:
- rebased on v6.1-rc7+
- don't enable ppkb-manager by default, to enable it manually use:
    echo echo 0 > /sys/devices/platform/keyboard-power/disabled
- ppp: make stk3311 gpio input if bootloader does leave it as output
  (fixes probe issues on phones with broken bootloaders)
2022-12-04:
- rebased on v6.1-rc7+
- don't reinitialize bluetooth on Pinephone during resume
2022-11-28:

- pinephone keyboard: wait for 100ms after enabling power supply and before
  probing
2022-11-01:
- rebased on v6.1-rc3
- add pinephone keyboard power manager driver
  - this driver manages charging cycle of both batteries and provides
    LED triggers, uevents and combined state in debugfs/kbpwr/state usable
    for summary capacity/discharge rate reporting
  - the driver optimizes for the highest power efficiency (power is used
    more directly without needless recharging of phone's battery from the
    keyboard battery)
  - the driver also performs calibration of kb battery internal resistance
    to improve reliability of capacity reporting of keyboard battery
  - the driver optionally provides emergency shutdown when both batteries
    are almost discharged
- make various PMIC drivers report battery capacity in uWh to userspace
  to make calculations for total capacity of multi-battery setup with
  different sized batteries more meaningful
- move to mainlined pinephone-keyboard driver
- ported sun6i-csi patches over to the 6.1 (base driver was changed quite
  a lot in rc2, so multicamera support needed to be rewritten from scratch)
- fixed pinephone keyboard current reporting (with large currents, the
  keyboard would sometimes report incorrect negative values due to integer
  overflow)
- renamed ppp selfie camera sensor subdevice name to be mainline compatible
- ppkb: allowed to disable special handling of FN layer via module parameter
  (to make it possible to use Fn key as another modifier key in xkb)
- hopefully final fix for quartz64-a pcie register/address ranges map
- added buffer support for af8133j magnetometer driver
- removed useless error messages
- sun4i-drm (pinephone) DRM driver fixes
  - rewritten patches that fix layer positioning and fixed additional bugs
    in the driver (reconfiguring planes while crtc was turned off led to
    corruption/stale framebuffer being scanned to the display)
- pinephone: fix power key getting stuck after resume, when pressed and
  released quickly enough (reported by Aren)

- resolved clock frequency incompatibility between the sensor drivers
2022-05-21:
- rebase on v5.18-rc8
- stupid ass schematic for pinephone pro is completely confusing, which is one
  reason why world facing camera didn't work up to now. See for yourself:
  This https://megous.com/dl/tmp/39cbd011289c6818.png apparently means that
  IMX258 is connected to MIPI1_TX1/RX1 lol https://megous.com/dl/tmp/5f25b00ef0166252.png
  MIPI_RX0 is isp0 MIPI1_RX1 is isp1. Just by reading the camera sheet in the
  schematic, I happily assumed that naming signals MIPI_RX0, they actually really
  are MIPI_RX0, but alas. Anyway, I moved IMX258 sensor node in device tree
  to isp1, so that increases chances that users who have working connection
  to the sensor over I2C will have a working camera now. :) Please test and
  report back.
- some cleanup and patch re-ordering in ppp branches
- drop A64 idle states from DT (these should be auto-added by TF-A when supported;
  you need to build TF-A properly, though! check p-boot/fw for example)

2021-10-26:
- workadound broken HDMI HPD on Pinephone
  - this should make Alt-DP mode work on pinephones where it failed previously
    (reaching only DP state 0x03)
  - HPD is now signalled to HDMI PHY via a software route instead of in hardware
    (hardware is confirmed broken by the product design team, exactly as I discovered

  device ordering issues)
- updated to the latest rockchip/for-next branch
2021-10-18:
- fix various Pinephone Pro issues that prevented suspending to ram and broke
  PMIC and cause PMIC, touchscreen and fusb interrupt storms

  from me for me for poweroff + some patches from pgwipeout split to q64-5.15 and
  q64dts-5.15 branches)
- rebase on v5.15-rc1+

2021-06-16:
- rebase on linus/master (5.13-rc6+)
2021-06-05:
- rebase on linus/master (5.13-rc5)
- add support for runtime calibration of minimum duty cycle of PWM backlight
  (until now it was hardcoded in device tree)
  - minimum brightness calibration instructions (default for lth_brightness is 10%,
    meaning is 'PWM duty cycle at the lowest brightness setting'):

  echo 1 > /sys/class/backlight/backlight/brightness
  echo 1 > /sys/class/backlight/backlight/device/lth_brightness
  echo 2 > /sys/class/backlight/backlight/device/lth_brightness
  echo 3 > /sys/class/backlight/backlight/device/lth_brightness

  ... increase values until you like the minimum brightness

  ... then make sure to restore this value after each boot by writing it to
  /sys/class/backlight/backlight/device/lth_brightness

2021-06-05:
- rebase on linus/master (5.13-rc4+)
2021-05-31:
- rebase on linus/master (5.13-rc4)

2021-05-20:
- rebase on linus/master (5.13-rc2+)
- fixed up booting with fw_devlink=on (see fixes-5.13)
- applied Samuel's time travel avoidance fix https://patchwork.kernel.org/project/linux-arm-kernel/patch/20210515021439.55316-1-samuel@sholland.org/
  - this should fix occasional stalls and system hangs
- revert fine tuned OCV based capacity reporting, PMIC is not reporting OCV correctly
  so kernel has garbage input for the OCV -> capacity conversion and thus produces
  garbage output too (this stops large jumps in capacity when plugging in a charger
  and in general makes capacity reporting saner)
- fixed "NOHZ tick-stop error: Non-RCU local softirq work is pending, handler #08!!!"
- wifi driver no longer prevents dynticks from working
- improved (well..., added) suspend/resume code to anx7688 driver :)
  - fixes some issues caused by this driver ignoring the suspend/resume cycle

2021-05-01:
- fixed suspend failure of light/proximity sensor
- raise the default minimum frequency for mbus devfreq governor
  (you can still lower it in sysfs for higher runtime power savings at the cost
  of some performance, see /sys/class/devfreq and tune it there for your distro)
2021-04-26:
- rebase on 5.12 final
- fixed behavior with dumb charger (DCP) being forced to 500mA on boot from anx7688
  driver
- disable lradc wakeup by default (lowers the power consumption in suspend)
2021-04-25:
- rebase on linus/master
- I've created a patch that disables touchscreen controller during system sleep
  reducing power consumption by about 40mW in sleep (and by 130mW when touching
  the screen in sleep)
  - before: https://megous.com/dl/tmp/0533207eed42258c.png
  - after: https://megous.com/dl/tmp/5d504d680415e2e3.png
  - those power spikes are touch controller checking if there's a finger touching
    the screen, and those dense spikes are when the finger is actually touching
    the screen
- Added Samuel's DRAM downclocking patches
2021-04-19:
- rebase on 5.12-rc8
2021-04-12:

  supply change, for userspace to gracefully handle this condition)
2021-03-11:
- linus/master update
2021-03-09:
- linus/master update
2021-03-04:

- fixed anx7688 fw flashing timeout
- added Samuel's patches:
  - allow to use RTC wakeup when powered off
  - NVMEM driver for RTC data registers
- pulled in some fixes from linux-next into fixes-5.11
- disable MMC runtime PM again (causes issues on H5/H6 https://megous.com/dl/tmp/1eec9b1c7f03ad93.png)
- used nvmem reboot driver (suggested by Samuel in RFC patch) for rebooting to FEL,
  eMMC bootloader, various p-boot boot configs on either eMMC or SD card's bootfs filesystems,
  boot menu, etc. via reboot() syscall with extra arg (see LINUX_REBOOT_CMD_RESTART2)
  (p-boot is also updated to support this mechanism, as of 2021-02-15)
2021-02-08:
- rebased on 5.11-rc7
2021-02-04:
- rebased on linus/master
2021-01-30:
- rebased on linus/master
2021-01-27:
- tested on all my boards
- make HDMI audio sound card initializa again on H3/H5
- fix rebase regression in stmmac driver that broke ethernet on PC 2
2021-01-25:
- rebased on top of v5.11-rc5
- fix 8723cs bluetooth DT to load pinephone BT config file correctly (add -pinephone postfix)

2020-12-11:
- rebased on top of linus/master
2020-12-07:
- rebased on top of 5.10-rc7
2020-12-05:
- modem power driver: add more powerup modes and change interface for dumb and fastboot powerup
  - you can now write 2, 3 or 4 to .../powered sysfs file to select differnt powerup mode from
    the normal one (1)
  - this is useful for selecting alternate userspace configurations early in boot to allow
    tracing the userspace processes from early on for reverse engineering, and in the near
    future, it will be used to switch between original and fully-FOSS userspace code
    running on the modem's APPS CPU on powerup
    - see https://xnux.eu/log/#028
2020-12-02:
- fix WiFi blocking suspend
- improve modem power driver interaction with kernel's autosleep
- shorten resume times from 1.2s to 400ms (wifi driver optimization)
2020-11-30:
- I improved the anx7688 driver to actually respect PD capabilities of the source,
  and don't overload it. This should make it more likely to work with the USB-C
  docks when docks are powered.
- Pine64 dock can provide either 500mA when powered from regular USB-A charger
  (regardless of what kind of charger it is, it can't use more current from it)
- With my 3A PD charger, Pine64 dock will advertise 2600mA and Pinephone will
  now respect this limit.
- rebase on linus/master (5.10-rc6 atm)
- increase I2C clock for sensors and touchscreen/anx7688 from 100kHz to 400kHz
- added patch from https://patchwork.kernel.org/project/dri-devel/cover/20200222024210.18697-1-yuq825@gmail.com/#23237865
  for easier GPU debugging (suggested by bshah)
2020-11-28:
- rebased on linus/master
- replaced my 60FPS fix with a more mainlineable and better working solution from Roman Beranek
- disable 8723cs CONCURRENT_MODE, enable wifi 802.11z TDLS

My kernel's main integration branch is 'orange-pi-$VER' (this one).
No other branch is supposed to work alone. My defconfigs are tested
and work on the boards I support. Read the README.md for more info.

Only my branches based on the current mainline kernel branch are
maintained (those are usually the -rc# kernels!). You can find the
current mainline version here https://www.kernel.org/ (mainline: ...)

My prebuilt kernels can be found at https://xff.cz/kernels/ You can
use them to test that your board works, or just run them without
bothering with building everything yourself. I run them on all my
boards.

My website is https://xnux.eu and may contain useful advice.

Good luck!

    97ab3e8e · rust: alloc: fix dangling pointer in VecExt<T>::reserve() · 
    Rust changes for v6.10

The most notable change is the drop of the 'alloc' in-tree fork. This
is nicely reflected in the diffstat as a ~10k lines drop. In turn, this
makes the version upgrades way simpler and smaller in the future, e.g.
the latest one in commit 56f64b370612 ("rust: upgrade to Rust 1.78.0").

More importantly, this increases the chances that a newer compiler
version just works, which in turn means supporting several compiler
versions is easier now. Thus we will look into finally setting a minimum
version in the near future.

Toolchain and infrastructure:

 - Upgrade to Rust 1.78.0.

   This time around, due to how the kernel and Rust schedules have
   aligned, there are two upgrades in fact. These allow us to remove one
   more unstable feature ('offset_of') from the list, among other
   improvements.

 - Drop 'alloc' in-tree fork of the standard library crate, which means
   all the unstable features used by 'alloc' (~30 language ones, ~60
   library ones) are not a concern anymore.

 - Support DWARFv5 via the '-Zdwarf-version' flag.

 - Support zlib and zstd debuginfo compression via the
   '-Zdebuginfo-compression' flag.

'kernel' crate:

 - Support allocation flags ('GFP_*'), particularly in 'Box' (via
   'BoxExt'), 'Vec' (via 'VecExt'), 'Arc' and 'UniqueArc', as well as in
   the 'init' module APIs.

 - Remove usage of the 'allocator_api' unstable feature.

 - Remove 'try_' prefix in allocation APIs' names.

 - Add 'VecExt' (an extension trait) to be able to drop the 'alloc'
   fork.

 - Add the '{make,to}_{upper,lower}case()' methods to 'CStr'/'CString'.

 - Add the 'as_ptr' method to 'ThisModule'.

 - Add the 'from_raw' method to 'ArcBorrow'.

 - Add the 'into_unique_or_drop' method to 'Arc'.

 - Display column number in the 'dbg!' macro output by applying the
   equivalent change done to the standard library one.

 - Migrate 'Work' to '#[pin_data]' thanks to the changes in the 'macros'
   crate, which allows to remove an unsafe call in its 'new' associated
   function.

 - Prevent namespacing issues when using the '[try_][pin_]init!' macros
   by changing the generated name of guard variables.

 - Make the 'get' method in 'Opaque' const.

 - Implement the 'Default' trait for 'LockClassKey'.

 - Remove unneeded 'kernel::prelude' imports from doctests.

 - Remove redundant imports.

'macros' crate:

 - Add 'decl_generics' to 'parse_generics()' to support default values,
   and use that to allow them in '#[pin_data]'.

Helpers:

 - Trivial English grammar fix.

Documentation:

 - Add section on Rust Kselftests to the "Testing" document.

 - Expand the "Abstractions vs. bindings" section of the "General
   Information" document.

  • x86-irq-2024-05-12

    6ecc2e79 · x86/irq: Use existing helper for pending vector check · 
    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.

  • timers-core-2024-05-12

    a3825a76 · Merge tag 'timers-v6.10-rc1' of https://git.linaro.org/people/daniel.lezcano/linux into timers/core · 
    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.

  • irq-core-2024-05-12

    382d2ffe · irqchip/gic-v3-its: Remove BUG_ON in its_vpe_irq_domain_alloc · 
    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
