Hi Felipe, Greg,
Is it possible to apply this ? USB is broken on 5.8 stable and 5.9-rc on

Hi,
I've updated the yaml and post it in the patch series v3[1].
But I still keep the vendor specific property mstar,irqs-map-range as I

The current implementation reduces the sampling rate by half

geni SE major version is greater than 2 and geni SE minor version

This implementation fails when the version is 3 or greater.

I expect Michael Ellerman will take the patch through his tree.
When using 128-bit interrupt-remapping table entry (IRTE) (a.k.a GA mode),
current driver disables interrupt remapping when it updates the IRTE
so that the upper and lower 64-bit values can be updated safely.
However, this creates a small window, where the interrupt could
arrive and result in IO_P
Currently, the RemapEn (valid) bit is accidentally cleared when
programming IRTE w/ guestMode=0. It should be restored to
the prior state.

Hi all,
Today's linux-next merge of the rcu tree got a conflict in:

Introduce tests to cover simple scenarios where user is watching
memory which can be accessed by kernel as well. We also support
_MODE_EXACT with _SETHWDEBUG interface. Move those testcases out-
side of _BP_RANGE condition. This will help to test _MODE_EXACT
scenarios when CONFIG_HAVE_HW_BREAKPOINT
Vector load/store instructions are special because they are always
aligned. Thus unaligned EA needs to be aligned down before comparing
it with watch ranges. Otherwise we might consider valid event as
invalid.

On powerpc, ptrace watchpoint works in one-shot mode. i.e. kernel
disables event every time it fires and user has to re-enable it.
Also, in case of ptrace watchpoint, kernel notifies ptrace user
before executing instruction.

When kernel is compiled with CONFIG_HAVE_HW_BREAKPOINT=N, user can
still create watchpoint using PPC_PTRACE_SETHWDEBUG, with limited
functionalities. But, such watchpoints are never firing because of
the missing privilege settings. Fix that.

Patch #1 fixes issue for quardword instruction on p10 predecessors.
Patch #2 fixes issue for vector instructions.

The fix uses HW_BRK_TYPE_PRIV_ALL for

There are couple of places where we set len but not hw_len. For
