As done in commit 944a45abfabc ("arm64: kdump: Reimplement crashkernel=X")
and commit 4831be702b95 ("arm64/kexec: Fix missing extra range for
crashkres_low.") for arm64, while implementing crashkernel=X,[high,low],
riscv should have excluded the "crashk_low_res" reserved ranges from
the crash kernel memory to prevent them from being exported through
/proc/vmcore, and the exclusion would need an extra crash_mem range.
Just simply tested on qemu with crashkernel=4G with kexec in [1] mentioned
in [2]. And the second kernel can be started normally.
# dmesg | grep crash
[ 0.000000] crashkernel low memory reserved: 0xf8000000 - 0x100000000 (128 MB)

In get_crash_memory_ranges(), if crash_exclude_mem_range() failed
after realloc_mem_ranges() has successfully allocated the cmem
memory, it just returns an error but leaves cmem pointing to
the allocated memory, nor is it freed in the caller
update_crash_elfcorehdr(), which cause a memory leak, goto out
to free the cmem.

The crash memory allocation, and the exclude of crashk_res, crashk_low_res
and crashk_cma memory are almost identical across different architectures,
This patch set handle them in crash core in a general way, which eliminate
a lot of duplication code.
And add support for crashkernel CMA reservation for arm64 and riscv.
Also add support for arm64 crash hotplug.
This patch set is rebased on v7.1-rc1.
Basic second kernel boot test were performed on QEMU platforms for x86,
ARM64 and RISC-V architectures with the following parameters:
"cma=256M crashkernel=4G crashkernel=64M,cma"
For first kernel, there will be such log:
# dmesg | grep crash
[ 0.000000] crashkernel low memory reserved: 0xe8000000 - 0xf0000000 (128 MB)
[ 0.000000] crashkernel reserved: 0x000000023e600000 - 0x000000033e600000 (4096 MB)
[ 0.000000] crashkernel CMA reserved: 64 MB in 1 ranges
# dmesg | grep cma
[ 0.000000] cma: Reserved 256 MiB at 0x00000000f0000000
[ 0.000000] cma: Reserved 64 MiB at 0x0000000100000000
For second kernel, there will be such log:
[ 0.000000] OF: fdt: Looking for usable-memory-range property...
[ 0.000000] OF: fdt: cap_mem_regions[0]: base=0x000000023e600000, size=0x0000000100000000

Changes in v15:
- Unify the subject prefix formats as Huacai suggested.
- Fix powerpc pre-existing NULL pointer dereference [Sashiko [1]]
- Fix powerpc pre-existing __merge_memory_ranges() memory range
truncation [Sashiko [1]].
- Fix pre-existing arm64 CMA page leaks [Sashiko[2]].
- Fix pre-existing crash_load_dm_crypt_keys() Use-After-Free and
Double Free issue [Sashiko[3]].
- Fix vfree(headers) and uninitialized variables issue
and simplify the fix [Sashiko[2]].

lock, unify and simplify the fix of TOCTOU buffer overflow via memory
region padding [Sashiko[4]].
- Fix the arm64 crash dump issues in Sashiko[5].

I might be missing something but can't we just call
iio_val_s64_compose()? Likely even inline in sysfs_emit_at()?
It would match your call to iio_val_s64_decompose() below.
And the above makes me wonder if the compose()/decompose() are not the
only helpers we need? At least in terms of parameters? I mean, just
assuming we only have two integers instead of allowing s32* and opening
the door for misbehave :)?
Don't feel too strong about the above anyways!

* [PATCH v17 net-next 06/11] net/nebula-matrix: add common resource implementation
From: illusion.wang @ 2026-06-01 9:31 UTC (permalink / raw)
To: dimon.zhao, illusion.wang, alvin.wang, sam.chen, netdev
Cc: andrew+netdev, corbet, kuba, horms, linux-doc, pabeni,
vadim.fedorenko, lukas.bulwahn, edumazet, enelsonmoore, skhan,

In-Reply-To: <20260601093149.25905-1-illusion.wang@nebula-matrix.com>
The Resource layer processes the entries/data of various modules within
the processing chip to accomplish specific entry management operations,
this describes the module business capabilities of the chip and the data
it manages.
The resource layer comprises the following sub-modules: common,
interrupt, and vsi(txrx,queue not contained this time)
This patch provides the common part, including the conversion
relationships among vsi_id, func_id, eth_id, and pf_id. These
relationships may be utilized in the upper layer or the resource layer.
Key Assumptions:
- nbl_res_start() initializes VSI/Eth/PF data structures **only for
control devices** (`common->has_ctrl == true`).
- APIs like nbl_res_func_id_to_vsi_id() **are guaranteed to be called
only on control devices** by the framework's dispatch layer.

* [PATCH v17 net-next 11/11] net/nebula-matrix: add common dev start/stop operation
From: illusion.wang @ 2026-06-01 9:31 UTC (permalink / raw)
To: dimon.zhao, illusion.wang, alvin.wang, sam.chen, netdev

In-Reply-To: <20260601093149.25905-1-illusion.wang@nebula-matrix.com>
This patch wires up nbl_dev_start() and nbl_dev_stop() to configure
the MSI-X map, allocate vectors, and request/enable the mailbox IRQ.
It also replaces module_pci_driver() with explicit init/exit functions
that additionally create and destroy the driver's workqueue via
nbl_common_create_wq() / nbl_common_destroy_wq(), which is needed
because the new IRQ handler schedules work through
nbl_common_queue_work().

* [PATCH v17 net-next 09/11] net/nebula-matrix: add Dispatch layer implementation
From: illusion.wang @ 2026-06-01 9:31 UTC (permalink / raw)
To: dimon.zhao, illusion.wang, alvin.wang, sam.chen, netdev
Cc: andrew+netdev, corbet, kuba, horms, linux-doc, pabeni,
vadim.fedorenko, lukas.bulwahn, edumazet, enelsonmoore, skhan,

In-Reply-To: <20260601093149.25905-1-illusion.wang@nebula-matrix.com>
This patch introduces a control-level routing mechanism for the Dispatch layer,
supporting direct and channel routing paths based on declared control levels.
Routing is controlled by two components:
1. Interface-declared control levels (per operation)
Each operation interface declares its required control level:
- NBL_DISP_CTRL_LVL_MGT: management operations
- NBL_DISP_CTRL_LVL_NET: network operations
2. Upper-layer configured control levels (per PF driver)
The PF driver configures which control levels use the direct path
via nbl_disp_init().
Current state:
- Regular PF: configures NET_LVL at Dispatch layer.
NBL_DISP_CTRL_LVL_NET is wired in nbl_disp_init() but not yet used
by any operation. All operations declare ctrl=NBL_DISP_CTRL_LVL_MGT,
so they all fall through to the CTRL_LVL_MGT branch and use the
channel path. The direct path for NET_LVL is reserved for future
high-performance network operations.
- Management PF: configures both NET_LVL and CTRL_LVL.
Since every operation declares ctrl=NBL_DISP_CTRL_LVL_MGT,
test_bit(MGT, ctrl_lvl) is true for every op, so all ops resolve
to func (direct path), not msg_req (channel path).
Future work:
Update NBL_DISP_OPS_TBL to declare ctrl=NBL_DISP_CTRL_LVL_NET for
network operations, enabling direct path routing.
Message Handling Framework:
The Channel path is used by all current operations. This design
allows the framework to be extended later to support direct HW
access for high-performance network operations without changing
the channel layer or existing control-plane operations.
Resource Layer Locking Strategy (related to this patch):
Mutex protection in nbl_dispatch_mgt:
- configure_msix_map(): LOCKED (via NBL_OPS_CALL_LOCK_RET)
- destroy_msix_map(): LOCKED
- set_mailbox_irq(): LOCKED
- init_chip_module(): UNLOCKED
- deinit_chip_module(): UNLOCKED
- get_vsi_id(): UNLOCKED
- get_eth_id(): UNLOCKED
Design rationale for unlocked call sites:
1. init_chip_module() / deinit_chip_module():
- Called ONLY from control path (PF0)
- These are init/teardown functions that run sequentially
- No concurrent access possible because:
a) Called during driver probe/remove
b) Only one control device exists
- Safe to call without mutex
2. get_vsi_id() / get_eth_id():
- These are READ-ONLY operations
- They only query existing state, never modify it
- Even if called concurrently with locked operations:
a) Reading shared state without lock is safe on most
architectures (torn reads are acceptable for IDs)
b) The locked operations that MODIFY state are:
- configure_msix_map (allocates resources)
- destroy_msix_map (frees resources)
- set_mailbox_irq (modifies hw state)
c) Reading while writing is safe if:
- Writer holds lock (prevents concurrent writes)
- Reader doesn't care about torn reads (IDs are atomic)
Mutex purpose:
The ops_mutex_lock protects MODIFY operations on shared
resource state (MSI-X map allocation, hardware configuration).
It does NOT protect read-only queries or ctrl-path init/teardown.
This is a deliberate design choice: locking only the
critical sections minimizes contention while maintaining
safety for the common case (concurrent reads).

* [PATCH v17 net-next 08/11] net/nebula-matrix: add vsi resource implementation
From: illusion.wang @ 2026-06-01 9:31 UTC (permalink / raw)
To: dimon.zhao, illusion.wang, alvin.wang, sam.chen, netdev
Cc: andrew+netdev, corbet, kuba, horms, linux-doc, pabeni,
vadim.fedorenko, lukas.bulwahn, edumazet, enelsonmoore, skhan,
hkallweit1, open list
In-Reply-To: <20260601093149.25905-1-illusion.wang@nebula-matrix.com>
This patch adds the VSI (Virtual Station Interface) resource
implementation for the Nebula Matrix Leonis hardware.
This driver only supports little-endian architecture
HW layer overview:
The HW layer code is highly chip-specific and may benefit from
additional review since it cannot be cross-checked against other
implementations.
DP sub-init modules (called from nbl_dp_init()):

- dsch, ustore, dstore: Scheduling and Store modules
- dvn, uvn, uqm: Virtual Network and Queue Management
- nbl_shaping_init(): Traffic shaping configuration
Chip init sequence (nbl_hw_init_chip_module()):
1. nbl_dp_init() — All DP sub-modules above
2. nbl_intf_init() — Host adapter padpt flow control
- nbl_host_padpt_init() — Host padpt flow control registers
3. nbl_write_all_regs() — Bulk P4 register data loading
4. nbl_hw_set_driver_status() + nbl_flush_writes()

* [PATCH v17 net-next 03/11] net/nebula-matrix: add chip related definitions
From: illusion.wang @ 2026-06-01 9:31 UTC (permalink / raw)
To: dimon.zhao, illusion.wang, alvin.wang, sam.chen, netdev
Cc: andrew+netdev, corbet, kuba, horms, linux-doc, pabeni,
vadim.fedorenko, lukas.bulwahn, edumazet, enelsonmoore, skhan,
hkallweit1, open list
In-Reply-To: <20260601093149.25905-1-illusion.wang@nebula-matrix.com>
This patch adds chip-related register definitions for the Leonis
hardware and introduces nbl_write_all_regs(), which programs a large
set of P4 configuration tables at chip initialization time.
1. nbl_hw.h/nbl_hw_leonis.h
chip-related reg definitions
2. nbl_hw_leonis_regs.c
P4 configuration that will be invoked during chip initialization
These nbl_sec*_data are used to configure P4-related registers. The
driver’s functionality depends heavily on these register settings. But
they can be not marked __initdata. Because it will be called by
pci_driver.probe.They also should not be moved into firmware files,
as the software functionality is tightly coupled with these
configurations.If they were moved to firmware,users could easily end up
with mismatched versions of the firmware and the kernel driver module,
leading to functional inconsistencies or system malfunctions.

+ * nbl_write_all_regs - Write initial register values during probe
+ *
+ * Context: This function is called ONLY during PCI probe (single-threaded,
+ * before any interrupts or concurrent access are possible). The reg_lock
+ * is intentionally NOT acquired here because:
+ * 1. Probe runs before device is registered to subsystem
+ * 2. No other thread can access this device yet
+ * 3. reg_lock is a spinlock_t (safe in atomic), but acquiring it
+ * here is redundant since probe is single-threaded before
+ * device registration
+ * Note: SEC block sizes are multiples of NBL_SEC_BLOCK_SIZE (>= 2x for
+ * multi-block sections). flush_writes() is placed inside the loop at
+ * block boundaries for multi-block sections, and outside for single-block
+ * or sub-block sections.
+ *
+ * The 139 sections are intentionally identified by index rather than by
+ * name. The hardware block layout is fixed and documented internally;
+ * adding string names would increase the binary size without providing
+ * any functional benefit to the driver or to users.

* [PATCH v17 net-next 05/11] net/nebula-matrix: add channel layer
From: illusion.wang @ 2026-06-01 9:31 UTC (permalink / raw)

In-Reply-To: <20260601093149.25905-1-illusion.wang@nebula-matrix.com>
A channel management layer provides a structured approach to handle
communication between different components and drivers. Here's a summary
of its key functionalities:
1. Message Handling Framework
Message Registration: Functions (nbl_chan_register_msg) allow dynamic
registration of message handlers for specific message types, enabling
extensible communication protocols.
Message Sending/Acknowledgment: Core functions (nbl_chan_send_msg,
nbl_chan_send_ack) handle message transmission, including asynchronous
operations with acknowledgment (ACK) support. Received ACKs are
processed via nbl_chan_recv_ack_msg.
Hash-Based Handler Lookup: A hash table (`handle_hash_tbl`) stores
message handlers for efficient O(1) lookup by message type. The
entire table is removed via `nbl_chan_remove_msg_handler` during
driver teardown (per-message-type removal is not implemented
in this version).
2. Channel Types and Queue Management
Mailbox Channel: For direct communication between PF0 and Other PF.
Queue Initialization: Functions (nbl_chan_init_queue,
nbl_chan_init_tx_queue) allocate resources:
- TX descriptors: dmam_alloc_coherent()
- RX descriptors: dmam_alloc_coherent()
- TX/RX buffer metadata arrays (txq->buf, rxq->buf): devm_kcalloc()
Queue Teardown: nbl_chan_teardown_queue() stops queues, cancels
pending work items (clean_task), and destroys mutexes. It does NOT
free DMA memory, which is released automatically via devm on driver
remove.
IMPORTANT - Resource Lifecycle Design:
DMA memory allocated with dmam_alloc_coherent() is intentionally NOT
freed in nbl_chan_teardown_queue(). The queues are allocated once
during driver probe and freed only during driver remove (when all
devm_ resources are released). This assumes queues are NOT dynamically
torn down and recreated per-PF during normal operation.
Queue Configuration: Hardware-specific queue parameters (e.g., buffer
sizes, entry counts) are set via nbl_chan_config_queue, with hardware
interactions delegated to hw_ops.
3. Hardware Abstraction Layer (HW Ops)
Hardware-Specific Operations: The nbl_hw_ops structure abstracts
hardware interactions: queue configuration (config_mailbox_txq/rxq),
tail pointer updates (update_mailbox_queue_tail_ptr).

* [PATCH v17 net-next 07/11] net/nebula-matrix: add intr resource implementation
From: illusion.wang @ 2026-06-01 9:31 UTC (permalink / raw)
To: dimon.zhao, illusion.wang, alvin.wang, sam.chen, netdev
Cc: andrew+netdev, corbet, kuba, horms, linux-doc, pabeni,
vadim.fedorenko, lukas.bulwahn, edumazet, enelsonmoore, skhan,
hkallweit1, open list
In-Reply-To: <20260601093149.25905-1-illusion.wang@nebula-matrix.com>
This patch adds the nbl_interrupt module for management of driver-private
MSI-X indices, plus hw_ops callbacks to program the function MSI-X mapping
registers, configure MSI-X info, and enable mailbox interrupts.
Key interfaces:
- configure_msix_map: Allocates driver-private global MSI-X indices
(interrupt_net_bitmap / interrupt_others_bitmap)
and programs the hardware MSI-X mapping registers
(NBL_PCOMPLETER_FUNCTION_MSIX_MAP).
The actual PCI MSI-X vector allocation is done
by nbl_dev_alloc_msix_intr().
- destroy_msix_map: Releases MSI-X indices and tears down the mapping.
- set_mailbox_irq: Enables/disables a specific mailbox interrupt.
- configure_msix_info: Programs PADPT_HOST_MSIX_INFO and
PCOMPLETER_HOST_MSIX_FID_TABLE.
The patch does not use kernel MSI-X allocation primitives
(pci_alloc_irq_vectors, pci_msix_alloc_irq_at, irq_domain). It manages
a driver-private global index space and programs vendor-specific
MSI-X mapping registers.
Note: Mutual exclusion for configure_msix_map, destroy_msix_map, and
enable_mailbox_irq is handled by the dispatch layer; these functions
assume the caller already holds the necessary lock.

* [PATCH v17 net-next 04/11] net/nebula-matrix: channel msg value and msg struct
From: illusion.wang @ 2026-06-01 9:31 UTC (permalink / raw)
To: dimon.zhao, illusion.wang, alvin.wang, sam.chen, netdev
Cc: andrew+netdev, corbet, kuba, horms, linux-doc, pabeni,

In-Reply-To: <20260601093149.25905-1-illusion.wang@nebula-matrix.com>
This patch introduces the channel message ID enumeration and several
message parameter structures for the nebula-matrix driver.
To ensure compatibility, the msg ID values are fixed, and fields can
only be appended to existing structures, not removed. Additionally,
any newly added fields must be placed on new Data Words (DWs) to
maintain alignment and compatibility. For array-type fields,
the length of individual array members cannot be changed once defined.
When modifying request structures, if a new field is added, the
corresponding response function must define a new stack variable
of the updated request message structure. The newly added fields
should be initialized to invalid values, and a minimal copy of the
original data should be performed to preserve compatibility with
existing implementations.

* [PATCH v17 net-next 02/11] net/nebula-matrix: add our driver architecture
From: illusion.wang @ 2026-06-01 9:31 UTC (permalink / raw)
To: dimon.zhao, illusion.wang, alvin.wang, sam.chen, netdev
Cc: andrew+netdev, corbet, kuba, horms, linux-doc, pabeni,

In-Reply-To: <20260601093149.25905-1-illusion.wang@nebula-matrix.com>
This commit introduces the baseline driver architecture for the
nebula-matrix networking device. It establishes the Hardware, Channel,
Resource, Dispatch, and Device layers for device management.
our driver architecture:
Hardware (HW), Channel, Resource, Dispatch, and Device Layer
Struct Initialization/Deinitialization, and Operation Set Registration/
Unregistration
Our driver architecture is relatively complex because the code is highly
reusable and designed to support multiple features. Additionally, the
codebase supports multiple chip variants, each with distinct
hardware-software interactions.
To ensure compatibility, our architecture is divided into the following
layers:
1. Dev Layer (Device Layer)
The top-level business logic layer where all operations are
device-centric. Every operation is performed relative to the device
context. The intergration of base functions encompasses:
management(ctrl only for leonis pf0), network(net_dev,this time not
contained),common.
2. Dispatch Layer
The distribution from services to specific data operations is mainly
divided into two types: direct pass-through and handling by the
management PF. It shields the upper layer from the differences in
specific underlying locations.
It describes the processing locations and paths of the services.
3. Resource Layer
Handles tasks dispatched from Dispatch Layer. These tasks fall into two
categories:
3.1 Hardware control
The Resource Layer further invokes the HW Layer when hardware access is
needed, as only the HW Layer has OS-level privileges.
3.2 Software resource management
Operations like packet statistics collection that don't require hardware
access.
4. HW Layer (Hardware Layer)
Serves the Resource Layer by interacting with different hardware
chipsets.Writes to hardware registers to drive the hardware based on
Resource Layer directives.
5. Channel Layer
Handle communication between PF0(has ctrl func) and other PF,and provide
basic interaction channels.
6. Common Layer
Provides fundamental services

* [PATCH v17 net-next 00/11] nbl driver for Nebulamatrix NICs
From: illusion.wang @ 2026-06-01 9:31 UTC (permalink / raw)
To: dimon.zhao, illusion.wang, alvin.wang, sam.chen, netdev
Cc: andrew+netdev, corbet, kuba, horms, linux-doc, pabeni,
vadim.fedorenko, lukas.bulwahn, edumazet, enelsonmoore, skhan,
hkallweit1, open list
This patch series represents the first phase. We plan to integrate it in
two phases: the first phase covers mailbox and chip configuration,
while the second phase involves net dev configuration.
Together, they will provide basic PF-based Ethernet port transmission and
reception capabilities.
After that, we will consider other features, such as ethtool support,
flow management, adminq messaging, VF support, debugfs support, etc.

You should be able to easily support regulators through pmbus. I meant
something like:

I know. I mixed a bit. I related it to devm because then we don't need
the error handling and then we can just do `return dev_err_probe()`.

And the above is a bit why I still like dev_err_probe() even if
EPROBE_DEFFER is not to be handled. I like that we can just return
rather than:
dev_err()
return ret;
Also it unifies error logs with the same style (for printing error
codes).

One small thing, I think we should probably keep the smp_wmb(), and just
move it before the earlier pmd_populate().
IIUC, the ordering we want is still:
clear old PTEs
smp_wmb()
pmd_populate()
so another CPU cannot walk through the re-installed PMD and still observe
the old PTEs, right?

In fact I think the HDBSS is the first one with non-fixed size.

OK, I agree, it is better to keep this thing arch-specific. Doing a

如何使用 usbmon 收集原始文本跟踪信息
====================================
-与数据包套接字不同，usbmon 提供了一种接口，
-可以输出文本格式的跟踪信息。这样做有两个目的：
-第一，在更完善的格式最终确定之前，
-它作为工具间通用的跟踪交换格式；
-第二，在不使用工具的情况下，人们也可以直接阅读这些信息。

原始文本数据格式
================
-目前支持两种格式：原始格式，也就是 ``1t`` 格式，
-以及 ``1u`` 格式。``1t`` 格式在内核 2.6.21 中已被废弃。
-``1u`` 格式增加了一些字段，例如 ISO 帧描述符、
-``interval`` 等。它生成的行会稍长一些，
-但在其他方面是 ``1t`` 格式的完整超集。
-
-如果程序需要区分上述两种格式，
-可以查看 ``address`` 字段（见下文）。
-如果其中有两个冒号，就是 ``1t`` 格式；
-否则是 ``1u`` 格式。
-
-任何文本格式的数据由一系列事件组成，
-如 URB 提交、URB 回调、提交错误等。
-每个事件对应单独的一行文本，
-由使用空白符间隔的若干字段组成。
-字段的数量与位置可能取决于事件类型，
-但以下字段对所有类型都通用：
-
-下面按从左到右的顺序列出这些共有字段：
-
-- URB Tag。用于标识 URB，通常是 URB 结构体在内核中的地址
- （以十六进制表示），
- 但也可能是序号或其他合理的唯一字符串。
-
-- 时间戳（微秒），十进制数字。
- 时间戳的精度取决于可用时钟，
- 因此可能远差于
- 1 微秒（例如实现使用的是 jiffies）。
-
-- 事件类型。它表示的是事件的格式，而不是 URB 的类型。
- 可用值为：``S`` 表示提交，``C`` 表示回调，``E`` 表示提交错误。
-
-- ``Address`` 字段（以前称作 ``pipe``）。
- 它包含四个由冒号分隔的字段：
- URB 类型及方向、总线号、设备地址和端点号。类型与方向的编码如下：
-
- == == ==========================
- Ci Co 控制输入和输出
- Zi Zo 等时输入和输出
- Ii Io 中断输入和输出
- Bi Bo 批量输入和输出
- == == ==========================
-
- 总线号、设备地址和端点号使用十进制，但可能有前导零。
-
-- URB 状态字段。这个字段要么是一个字母，
- 要么是几个由冒号分隔的数字：
- URB 状态、``interval``、``start frame`` 和 ``error count``。
- 与 ``address`` 字段不同，除了状态外，其余字段都是可选的。
- ``interval`` 只会为中断和等时 URB 打印；``start frame`` 只会为
- 等时 URB 打印；错误计数只会在等时回调事件中打印。
-
- 状态字段是一个十进制数字，有时为负数，
- 对应 URB 的 ``status`` 字段。
- 对于提交事件，这个字段本身没有实际意义，
- 但为了便于脚本解析，它仍然存在。
- 当发生错误时，该字段包含错误码。
-
- 在提交控制包时，这个字段包含的是 ``Setup Tag``，
- 而不是一组数字。
- 判断 ``Setup Tag`` 是否存在很容易，因为它从来不是数字。
- 因此，如果脚本在这个字段里发现的是一组数字，
- 就会继续读取数据长度（等时 URB 除外）。
- 如果发现的是其他内容，比如一个字母，
- 那么脚本会先读取 ``Setup`` 包，再读取数据长度或等时描述符。
-
-- ``Setup`` 包由 5 个字段组成：
- ``bmRequestType``、``bRequest``、``wValue``、
- ``wIndex`` 和 ``wLength``。这些字段由 USB 2.0 规范定义。
- 如果 ``Setup Tag`` 为 ``s``，就可以安全地解码这些字段。
- 否则，说明 Setup 包虽然存在，但并未被捕获，此时各字段中会填入占位内容。

- 每个字段由三个用冒号分隔的十进制数字组成，

This looks wrong on a number of levels.
- If you want something generic, there is the existing dirty
log/bitmap. How this stuff is populated is none of the user's
business (trapping write accesses, dirty bit collection from the
PTs, or HW-generated log), and we don't need an extra feature for
it. Performance will obviously suck, but that's what you pay for
something abstracted and cross-architecture.
- If you want something architecture specific, then it can't be
generic, by definition. You get the raw speed and compatibility with
other arch-specific extensions.

Again, the generic framework exists, you just have to implement the
backend you want.
