I have just tested all gVisor syscall test cases with ptrace(Regs, FPRegs, TLS)
on Arm64 platform.
The test results are the same as before there was no patch.
My idea is that this kernel patch has no bad effects on gVisor.
Linux Kernel version: 5.7.0-rc6+
gVisor version:
When using mmap() on a prime imported buffer allocated by a
different driver (such as imx-drm) the later munmap() does
not correctly decrement the refcount of the original enaviv_gem_object,
leading to a leak.

kdb has to get messages on consoles even when the system is stopped.
It uses kdb_printf() internally and calls console drivers on its own.
It uses a hack to reuse an existing code. It sets "kdb_trap_printk"

kdb_printf() variant.

Software firmware nodes can provide a child node to its parent.
Since software node can be secondary, we need a mechanism to access
the children. The idea is to list children of the primary node first
and when they are finished, continue with secondary node if available.

Use div_u64 for 64-bit division, and change sample_ns type to
unsigned int. Otherwise, the module will reference __udivdi3

Hi Christoph,
Can you also update the kerneldoc comment too?

pm_runtime_get_sync() increments the runtime PM usage counter even
the call returns an error code. Thus a pairing decrement is needed
on the error handling path to keep the counter balanced.

Remove the variable mrp_ring_state from switchdev_attr because is not
used anywhere.
The ring state is set using SWITCHDEV_OBJ_ID_RING_STATE_MRP.

It is not allow to have the same net bridge port part of multiple MRP
rings. Therefore add a check if the port is used already in a different
MRP. In that case return failure.

When a MRP instance is deleted, then restore the port according to the
bridge state. If the bridge is up then the ports will be in forwarding
state otherwise will be in disabled state.

This patch series adds small fixes to MRP implementation.
The following are fixed in this patch series:
- now is not allow to add the same port to multiple MRP rings
- remove unused variable
- restore the port state according to the bridge state when the MRP instance
is deleted

Hi!
My window manager stopped responding. I was able to recover machine

I started writing nice report, when session failed second time. And
then third time on next attempt.
Any ideas?
I'll send this out before this locks up...
Best regards,
With pseudo NMIs support available its possible to configure SGIs to be
triggered as pseudo NMIs running in NMI context. And kernel features
such as kgdb relies on NMI support to round up CPUs which are stuck in
hard lockup state with interrupts disabled.
This patch-set adds support for
Introduce a new inter processor interrupt as IPI_CALL_NMI_FUNC that
can be invoked to run special handlers in NMI context. One such handler
example is kgdb_nmicallback() which is invoked in order to round up CPUs
to enter kgdb context.
As currently pseudo NMIs are supported on specific arm64
Setup IPI_CALL_NMI_FUNC as a pseudo NMI using generic interrupt framework
APIs. In case a plarform doesn't provide support for pseudo NMIs, switch
back to IPI_CALL_NMI_FUNC being a normal interrupt.

Add support to handle SGIs as regular NMIs. As SGIs or IPIs defaults to a
special flow handler: handle_percpu_devid_fasteoi_ipi(), so skip NMI
handler update in case of SGIs.
Also, enable NMI support prior to gic_smp_init() as allocation of SGIs
as IRQs/NMIs happen as part of this routine.
arm64 platforms with GICv3 or later supports pseudo NMIs which can be
leveraged to round up CPUs which are stuck in hard lockup state with
interrupts disabled that wouldn't be possible with a normal IPI.
So instead switch to round up CPUs using IPI_CALL_NMI_FUNC. And in
case a particular arm64
