The hcall H_GET_PERF_COUNTER_INFO with counter request value as
PROCESSOR_BUS_TOPOLOGY(0XD0), can be used to get the system
topology information. To expose the system topology information,
patch adds sysfs file called "processor_bus_topology" to the
"/sys/devices/hv_gpci/interface/" of hv_gpci pmu
The hcall H_GET_PERF_COUNTER_INFO can be used to get data related to
chips, dimms and system topology, by passing different counter request
values.
Patchset adds sysfs files to "/sys/devices/hv_gpci/interface/"
of hv_gpci pmu driver, which will expose system topology information

Hi, Laurent,
I ran into a boot hang regression with latest upstream code, and it
took me a while to bisect the offending commit and workaround it.
Now I have tested this patch series on an Intel RaptorLake Hybrid
platform (4 Pcores with HT and 4

Though ARM64 has the hardware to do tlb shootdown, the hardware broadcasting is
not free. A simplest micro benchmark shows even on snapdragon 888 with only
8 cores, the overhead for ptep_clear_flush is huge even for paging out one page
mapped by only one process:
5.36% a.out

The entire scheme of deferred TLB flush in reclaim path rests on the
fact that the cost to refill TLB entries is less than flushing out
individual entries by sending IPI to remote CPUs. But architecture
can have different ways to evaluate that. Hence apart from checking
From: Barry Song
This patch does some preparation works to extend batched TLB flush to
arm64. Including:
- Extend set_tlb_ubc_flush_pending() and arch_tlbbatch_add_mm()
to accept an additional argument for address, architectures
like arm64 may need this for tlbi.
- Rename
From: Barry Song
on x86, batched and deferred tlb shootdown has lead to 90%
performance increase on tlb shootdown. on arm64, HW can do
tlb shootdown without software IPI. But sync tlbi is still
quite expensive.
Even running a simplest program which requires swapout can
prove this is true,
From: Yicong Yang
Currently we'll flush the mm in flush_tlb_batched_pending() to
avoid race between reclaim unmaps pages by batched TLB flush
and mprotect/munmap/etc. Other architectures like arm64 may
only need a synchronization barrier(dsb) here rather than
a full mm flush. So add

Hi, Dan,
My full name is wuyunchan， but that is too long.
So I use the wuych as simplification.
I will change it to my full name,

Hello,
v2 of this series was sent in June[1], code changes since then only affect
patch #1 where the dev_err invocation was adapted to emit the error code of
dpaa_fq_free(). Thanks for feedback by Maciej Fijalkowski and Russell King.
Other than that I added Reviewed-by tags for Simon Horman and
