Hi Nikolay,
Thanks for your comments.
The original intention is that I want to run a command to set single port into
QinQ mode,
the related commands are:
ip link set br0 type bridge vlan_protocol 802.1ad // this command will set all
ports under the bridge br0
ip link add link swp1 name

This patch uses the RVC support and encodings from bpf_jit.h to optimize
the rv64 jit.
The optimizations work by replacing emit(rv_X(...)) with a call to a
helper function emit_X, which will emit a compressed version of the
instruction when possible, and when RVC is enabled.
The JIT continues to

This patch makes the necessary changes to struct rv_jit_context and to
bpf_int_jit_compile to support compressed riscv (RVC) instructions in
the BPF JIT.
It changes the JIT image to be u16 instead of u32, since RVC instructions
are 2 bytes as opposed to 4.
It also changes ctx->offset and
This patch adds functions for encoding and emitting compressed riscv
(RVC) instructions to the BPF JIT.
Some regular riscv instructions can be compressed into an RVC instruction
if the instruction fields meet some requirements. For example, "add rd,
rs1, rs2" can be compressed into "c.add rd,
This patch series enables using compressed riscv (RVC) instructions
in the rv64 BPF JIT.
RVC is a standard riscv extension that adds a set of compressed,
2-byte instructions that can replace some regular 4-byte instructions
for improved code density.
This series first modifies the JIT to support

In previous discussion [1] and [2], we found that it is risky to
use max_pfn or totalram_pages to tell if 4GB mode is enabled.
Check 4GB mode by reading infracfg register, remove the usage
of the un-exported symbol max_pfn.
This is a step towards building mtk_iommu as a kernel module.

/proc/cpuinfo is great. It is omnipresent and since it is provided by

Hi Palmer:
Thanks for your reply.
Frankly, I didn't test ARCH_HAS_FAST_MULTIPLIER on RV32,
so I cannot put it in RISCV platform.
I am trying to comparing ARM64 with Riscv to find out more optimization
configurations.
I suggest to enable ARCH_HAS_FAST_MULTIPLIER on RV64 first.
If someone

Use kthread_create_worker to simplify the code and optimise
the manager struct: msm_drm_thread. With this change, we
could remove struct element (struct task_struct *thread &
struct kthread_worker worker), instead, use one point (struct
kthread_worker *worker).

This patch introduces two types of GPADL: HV_GPADL_{BUFFER, RING}. The
types of GPADL are purely the concept in the guest, IOW the hypervisor
treat them as the same.
The reason of introducing the types of GPADL is to support guests whose
page size is not 4k (the page size of Hyper-V hypervisor).
When PAGE_SIZE > HV_HYP_PAGE_SIZE, we need the ringbuffer size to be at
least 2 * PAGE_SIZE: one page for the header and at least one page of
the data part (because of the alignment requirement for double mapping).
So make sure the ringbuffer sizes to be at least 2 * PAGE_SIZE when
using
Both the base_*_gpa should use the guest page number in Hyper-V page, so
use HV_HYP_PAGE instead of PAGE.

When a guest communicate with the hypervisor, it must use HV_HYP_PAGE to
calculate PFN, so introduce a few hvpfn helper functions as the
counterpart of the page helper functions. This is the preparation for
supporting guest whose PAGE_SIZE is not 4k.

Since the hypervisor always uses 4K as its page size, the size of PFNs
used for gpadl should be HV_HYP_PAGE_SIZE rather than PAGE_SIZE, so
adjust this accordingly as the preparation for supporting 16K/64K page
size guests.

There will be more places other than vmbus where we need to calculate
the Hyper-V page PFN from a virtual address, so move virt_to_hvpfn() to
hyperv generic header.

Pure function movement, no functional changes. The move is made, because
in a later change, __vmbus_open() will rely on some static functions
afterwards, so we sperate the move and the modification of
__vmbus_open() in two patches to make it easy to review.

When communicating with Hyper-V, HV_HYP_PAGE_SIZE should be used since
that's the page size used by Hyper-V and Hyper-V expects all
page-related data using the unit of HY_HYP_PAGE_SIZE, for example, the
"pfn" in hv_page_buffer is actually the HV_HYP_PAGE (i.e. the Hyper-V
page) number.

Hyper-V always use 4k page size (HV_HYP_PAGE_SIZE), so when
communicating with Hyper-V, a guest should always use HV_HYP_PAGE_SIZE
as the unit for page related data. For storvsc, the data is
vmbus_packet_mpb_array. And since in scsi_cmnd, sglist of pages (in unit
of PAGE_SIZE) is used, we need
This patchset add the necessary changes to support guests whose page
size is larger than 4K.
Hyper-V always uses 4K as the page size and expects the same page size
when communicating with guests. That is, all the "pfn"s in the

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.
After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific

I'll take my word back.
It's not this patch problem, but by others.
I have 2 extra patches before the 3 patches so my system looks like
backports from ath.git 5.6-rc1 + linux kernel 4.4 (similar to OpenWrt)
On top of the working system, I cherry-picked these 5.
